Sun 3°00' Aries

Sun Aspects
Sun trine Pluto orb +1°15'
Sun sextile Moon orb +3°18'
Sun conjunction Mercury orb +9°26'
Sun sesqui-quadrate Saturn orb -2°01'
Planets: Sun

The Sun represents vitality, individuality, will-power and creative energy and honours. For a woman, it also represents her father, and later her husband. The Sun is one of the most important symbols in the birth chart, as much as the Ascendant, then the Moon (a bit less for a man), the ruler of the Ascendant and the fast-moving planets.

It's element is fire; it is hot and dry, it governs Leo, is in exaltation in Aries and is in analogy with the heart. It represents the boss, authority, beside the father and the husband ; the age of the Sun goes from 20 years old to about 40, following the Venus age when one is aware of his seductive power.

Temperament : Bilious

Characterology : Emotive, Active, Secondary, passionate type.

Sun in Aries

Your entourage is amazed by your energy, your courage and your boldness. Your reactions are quick, even instantaneous. Your enthusiasm prompts you to follow your natural impulses, even though you are not aware of all the consequences of your actions. Above all, you want to live each moment intensely, without fearing the future. Your enterprising spirit is supported by an acute sense of confrontation. Present! This is Aries answering the call. Any call, provided that there is some degree of new-ness or some challenge. If Aries’ dynamism and enterprising spirit are underlined, it is because the sign is more inclined to commit itself in the present and to start from scratch. This ability to take action on the spot in response to any stimulation also applies to the area of your relationships: you say outloud what you deem necessary to say, even if it means foolishly upsetting several persons. It is black or white, yes or no… often without balance! Beginning and undertaking are situations where you feel that you are in your element. Your qualities can also be expressed when you are bogged down in inextricable and complicated relationships: you know how to simplify things but you should beware not to do so in a caricatured manner.

Sun Dominant

If the Sun is part of your natal chart's planetary dominants, in astrology, you are said to be a Solarian: you loathe pettiness and Machiavellian manoeuvre, and you are fond of natural nobleness as well as of direct and honest attitudes. You endeavour to get out of muddled or dark situations as quickly as possible. Your need for transparency may lead you to make cut-and-dried judgments such as yes or no, and black or white. However, your honesty commands your entourage's consideration. At times, you come across as authoritarian. It is true that you never want to be thought of the notable absentee, and that you manage to make people pay attention to you, as well as to your plans and your assessments. To this end, the Solarian sometimes develops a great talent for placing himself under the spotlight without missing a single opportunity to arouse interest. Some other Solarians, although more discreet, still manage to be the focus of any debate, even in situations of exclusion. It is your way of being present even though you are actually not there... More than other people, you appreciate the esteem extended to you. It is useless to cheat with you, since in all areas you consider establishing enduring relationships only with those who love you, admire you, respect you, or express some degree of affection to you. Your will to straighten out your inter-personal relationships is your strength and sometimes, your Achilles' heel. You cannot achieve anything behind the scenes. Therefore, your comportment is marked with heroism, and your stands are devoid of ambiguity, in the sense that your commitments are unfailing, and your rebuffs, final.

Interpretation of the 3° Aries symbolic degree

"A man takes a walk in a forest where many plants of various species grow. Another man with shaggy hair hides behind the shrubs." (Janduz version)

Pragmatic, modest, and unsophisticated character. In spite of a great natural wisdom, one has no inclination for studies. One is driven by the sense of honour and by genuine generosity. The man hidden in the shrubs is not necessarily ill-intentioned. He may just be an original and independent person who prefers to remain out of the mainstream. In this lifetime, one can expect at least one major encounter which brings about crucial events, the positive or negative outcomes of which depend on the natal chart. All occupations related to security such as the police, the military, or the law are highly favoured. If in the natal chart, Mars is on this degree and forms hard aspects with the Sun and the Moon, he may portend a violent death.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

Moon quintile Mercury orb +0°44'
Moon semi-square Neptune orb +1°21'
Planets: Moon

The Moon represents instinctive reaction, unconscious predestination, everyday mood, sensitivity, emotions, the feminine side of the personality, intuition, imagination. For a man, she represents his mother and later his wife, and his relationship with women in general. For a woman, the Moon is almost as important as the Sun and the Ascendant. Her element is water, she is cold and moist, she rules Cancer, is in exaltation in Taurus and is in analogy with the stomach.

She symbolizes the mother, wife, the crowd, the Moon is associated with birth and childhood. Tradition also matches her with the end of life, after Saturn the old age, it is thus customary to go back to one's place of birth to die: the end of life meets the very beginning.

Temperament : Lymphatic

Characterology : Emotive, non Active and Primary type or Non-Emotive, non Active and Primary, Nervous or Amorphous type.

Moon in Gemini

On the day and at the time of your birth, the Moon was in the sign of Gemini. You easily adjust to all kinds of situations because your outgoing nature integrates the characteristics of your environment very quickly. You communicate your emotions, you share your pleasures, your joys… and your sorrows. Your lunar sign belongs to the Gemini-Sagittarius axis that is decidedly open on the external world. You display strong assimilation abilities and you readily adopt your entourage’s habits. Besides, your life setting does not necessarily have the stiff side that others may need to feel safe. You put up with rhythm changes and your balance is not upset by unforeseen events and contacts. On the contrary, you loathe solitude and you are very comfortable when you have to exchange and to relate to others. There is a danger that you very cautiously avoid: your adaptation capacity must not turn you into a chameleon and it is important that you pay due attention to your needs and your personal rhythms.

Moon Dominant

If the Moon is part of your natal chart's planetary dominants, in astrology, you are said to be a Lunarian: the driving force behind your actions is mainly the pursuit of well-being and tranquillity. Your sensitive and romantic self lives on those periods of rest during which you let your imagination wander at will. This is your way of finding inspiration and balance. Nothing is allowed to disturb your feeling of fulfilment and security within a harmonious cell, be it a family or a clan. More than other people, the Lunarian is attached to those moments during which one forgets one's worries and lets oneself cast adrift aimlessly, with no other goal than to be lulled into an ambiance, a situation, or a perfect moment. Many people do not understand such absences and their meaning, which is to regain strength. These people readily describe you with such unflattering terms as apathy and nonchalance. Never mind! Some inspirations require surrendering as well as striking a balance derived from alternate action and passivity. Your qualities are expressed to the fullest in situations which demand familiarity and privacy. Your capacities to respect and blend into your environment is at least as valuable as some other people's aggressive dispositions. However, you are well-advised to avoid indolence and renunciation out of laziness or indifference.

Interpretation of the 6° Gemini symbolic degree

"At the edge of a lake surrounded by mountains, two young women holding hands watch a swan swimming towards them." (Janduz version)

Contemplative, pleasant, and generous character. Even though the horizon is quite limited, life is stable, quiet, and devoid of uncertainties. One is blessed with numerous loyal friends, a nice entourage, and a happy marriage. In a female chart, this degree may indicate special loving ties with a sister or a twin, or the birth of twins.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

Sun conjunction Mercury orb +9°26'

Planets: Mercury

Mercury represents communication, logical and rational mind, intellectual skills. Earth is its element, it is cold and dry, and it rules Virgo and Gemini, is in exaltation in Virgo and is in analogy with the arms, hands, nervous system.

It represents tradesmen, lawyers, messengers; the age of Mercury goes from 8 or10 years old to about 15..

Temperament : Nervous

Characterology : Emotive, non Active and Primary type or Non-Emotive, Active and Primary, Nervous or Sanguine type.

Mercury in Pisces

Mercury describes your relationships, your communication skills and the way you relate to the external world. However, other astrological elements also influence these areas. The sign your Mercury occupies is significant only if Mercury is part of your planetary dominantes. In your chart, Mercury is in Pisces. You are connected to the world through your intuition. Contacts are established, and broken up, according to your sensitivity. Your perceptiveness is amazing. You soak into your environment in order to grasp its subtle games and you feel that you know things without learning them. You assimilate them unconsciously and you very sharply pick up hints and unformulated thoughts. Some sort of sixth sense.

Mercury Dominant

If Mercury is part of your natal chart's planetary dominants, in astrology, you are said to be a Mercurian: the tradition points out the importance of communication. From idle but enriching chatters to observation gift, such a dominant endows you with a wide range of expression. Human beings have one thousand facets and one thousand masks they wear according to circumstances and the fortunes of the game of life. You take the role of an observer who is avid for novelties, discoveries, and surprises. Everything catches your attention and becomes an opportunity for new encounters, relationships, and learning. The world amazes you, amuses you sometimes, and stimulates your curiosity. Because the most important thing is to discover, and because you consider that each new situation is packed with potentialities, you try to fill the gaps in your knowledge. Although your open-mindedness may scatter your centres of interest, it also enables you to carefully avoid sticking to only one immutable and rigid view. The slightest sign enables you to perceive the other side of the coin, as well as the infinite complexity of people and of situations. On the human plane, you seek the dialogue and the information without which you know that you are not able to fully grasp the nature of your interlocutor. This keen interest in the Unknown sharpens your inter-relational skills. All these qualities are traditionally associated with Mercury.

Interpretation of the 23° Pisces symbolic degree

"Under a dark sky enlightened by a moon crescent and a flash of lightning, two men are wrestling." (Janduz version)

Assertive, courageous, and discerning character endowed with physical and intellectual strength. One is free to use one's personal qualities at the service or justice and the collective good, or on the contrary, in the pursuit of reprehensible goals. In both cases, many hurdles and setbacks disrupt one's happiness and success. However, thanks to one's fortitude, one can overcome ordeals with flying colours. It is in the dark hours of the night that danger lurks.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

On the chessboard of your sentimental life, quite strange games enfold. Your affectivity is subtle, fabulous and unusual: love reinvents everything and anything becomes possible when your heart is sincere. You dream of a complete fusion and of giving yourself totally. No rules, no moral or social code is more important than the feeling of shared passion and than living for your partner. Your affective life is complex, sometimes mysterious: you don’t know why you love, or why you don’t love any more… Your sentimental life obeys a different logic than that of the external world. Love is elusive and fragile. Nothing is easier than to destroy a feeling and to forget a passion. Your sensitivity responds to an unknown call, a strange signal. Therefore, you may shift from intense and absolute feelings to cruel indifference. Although you don’t know why, you are being transformed. The most difficult thing is to love a real being and not a shadow. You give yourself to persons who can understand and respect the fragile realm of your affectivity.

Venus Dominant

If Venus is part of your natal chart's planetary dominants, in astrology, you are said to be a Venusian: you are a sensual and emotional person particularly receptive to the natural likes and dislikes aroused by your contact with people. You are prone to frequent instinctive aversions and true passions which are exclusively driven by the feeling of love. The heart has its reasons which Reason knows nothing of... Your balance is based on the richness of your affective life. Without love, the Venusian is resourceless, lost, and deprived of any reason for living. You have an obvious and strong will to charm and to arouse the attachments without which you cannot properly function. Every area of your life is thus marked by your affectivity. The danger is that you may "be taken in" by charm. In such cases, you would prefer to keep your emotions under better control. Thus, hyper-sensitivity has its own inconveniences. Nevertheless, better than anyone else, you know how to play with feelings and attractions. Although you are sometimes caught in the traps of an over sensitive emotionalism, feelings remain your best assets in many circumstances. There is another aspect to the Venusian dominant. According to the Tradition, this planet rules the Arts, and you are endowed with some degree of artistic dispositions, ranging from good to excellent.

Interpretation of the 12° Pisces symbolic degree

"A soldier is ready to shoot at no particular target with his bow while a woman drifts down the river in a small boat without oars." (Janduz version)

Boastful, coward, and selfish character prone to exaggeration. Unless the natal chart clearly indicates that one has courage, high ideals, and strong will, one shows strength when there is no danger and hides away when the situation requires real bravery.

Mars 22°25' Sagittarius

Mars Aspects
Mercury square Mars orb +1°08'
Mars inconjunction Neptune orb -0°14'
Mars sextile Uranus orb -2°34'
Planets: Mars

Mars represents the desire for action and physical energy, sexuality, strength. For a woman, Mars corresponds to the kind of man she's attracted to (but not especially in marriage which is rather symbolized by the Sun, Mars is the lover, not the husband). Fire is its element, it is hot and dry, and it rules Aries and Scorpio (along with Pluto), is in exaltation with Capricorn and is in analogy with the muscles and the spleen.

It represents the soldiers, sportsmen, warriors, surgeons, blacksmiths... ; the age of Mars goes from 42 to 50 years old.

Temperament : Bilious

Characterology : Emotive, Active, Primary type. It is a Choleric.

Mars in Sagittarius

The planet Mars indicates how you react to life concrete stimulations. It also describes your fighting spirit, your abilities to stand for yourself and to take action. With Mars in Sagittarius, your dynamism is aroused when you have to go ahead, to discover new life settings and to broaden your horizon. You have the soul of an adventurer! Your nature is straightforward, direct and enthusiastic and it is difficult for you to tell lies and to follow the tortuous paths of diplomacy. You do not fear danger and your scope of action has no limit. Because you feel concerned about all things, you readily commit yourself in collective struggles or actions. You feel that it is important to go beyond your limitations and to take action, especially in favour of events that are not related to you personally. You always inscribe an element into a wider content. This is how original solutions may emerge, even if it means that you have to exercise more pragmatism: reality may be impossible to ignore.

Mars Dominant

If Mars is part of your natal chart's planetary dominants, in astrology, you are said to be a Marsian: in your hand-to-hand struggle for life, you demonstrate an acute and active sense of confrontation with the world, with other people, and with your own destiny. You need to take action and to fight for your projects and your desires. You perceive all situations with deep intensity, and you react to the here and now without bothering to step back in order to ensure that events are under your control. You take up challenges with excessive foolhardiness as a consequence of your impulsiveness. However, better than anyone else, you know how to mobilise your resources in case of crisis. You take action whenever it is necessary to do so, and you are present in a timely manner. With Mars, your attitudes are dictated by the realities of the moment, by your emotions, and by everything which proved to have worked in the past. When this dominant is not well integrated, it may bring about an aggressive or impulsive behaviour. Therefore, you must learn to control your hyper-sensitivity and your fits of temper. You are also endowed with Marsian qualities: the fighting spirit and the taste for duel without which one may find oneself overwhelmed by events. When this willpower is well channelled, its precious energy enables to cope with all sorts of contingencies. There are a thousand ways to win, and a thousand challenges to take up with the enthusiasm and the dynamism which make life so worthy. A certain idea of life which is wild, passionate, and in tune with events.

Interpretation of the 22° Sagittarius symbolic degree

"A dagger with the hilt encrusted with precious stones pierces a heart caught in a wire screen." (Janduz version)

Selfish, jealous, and conceited character. One has difficulties in understanding that self-centredness harms relationships with friends or lovers, and that other people's aspirations must be given due consideration. This degree indicates unhappiness in love. If the natal chart concurs, there is a danger caused by a heart condition or a violent accident.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

Jupiter 11°39' Pisces

Jupiter Aspects
Venus conjunction Jupiter orb +0°28'
Moon square Jupiter orb -5°20'
Planets: Jupiter

Jupiter represents expansion and power, benevolence, large vision and generosity. Its element is Air, it is hot and moist, and it rules Sagittarius and Pisces (along with Neptune), is in exaltation with Cancer and is in analogy with the hips and endocrinal system.

It represents the governors, magistrates, professors, religious men too; the age of Jupiter goes from 50 to 55 or even 70 years old.

Temperament : Sanguine

Characterology : Emotive, Active, Primary type; it is an extrovert Choleric. Actually the humid version of Mars, inclined to action like him.

Jupiter in Pisces

The planet Jupiter symbolizes expansion, broadness and generosity. Jupiter is associated with the functions of synthesis, enthusiasm and optimism. In your natal chart, his house position is more important than his sign position because, like Saturn, Uranus, Neptune and Pluto, he is a slow planet. Many people born in the same period have Jupiter in the same sign. This is the reason why the sign occupied here is less meaningful than when it is occupied by the so-called fast planets, i.e. the Sun, the Moon, Mercury, Venus and Mars. Therefore, some caution is to be exercised as you read what follows. Jupiter in Pisces increases your natural generosity and your dedication capacity. Your empathy is strong and you are inclined to offer your strength and your enthusiasm to the most deprived people and to give unlimited assistance to others. Your imagination is powerful and your feelings may flare up easily: with your sensitivity on the alert and your unbridled affectivity, you belong to the category of people who intuitively detect other people’s sufferings and most valuable qualities of the heart, as if you were a human radar.

Jupiter Dominant

If Jupiter is part of your natal chart's planetary dominants, in astrology, you are said to be a Jupiterian: because this planet brings about a keen interest in social and professional success, the Tradition considers it to be beneficial. Indeed, you know how to adjust to events and to jump at the chance when it arises. The members of you entourage gladly entrust you with high responsibilities because they are often impressed by your learning skills and your adaptation abilities as you deal with new structures and new languages. What is the secret of your good star? It is your self-confidence which wins public support. Now, what is the secret of your charm? Definitely, enthusiasm, euphoria, and exaltation. Exaggeration also. When this dominant is well integrated, it is a factor of affluence and optimism, and a certain degree of joviality enables you to easily fit into various spheres. It constitutes your main asset to manage your life. However, you must at times curb your desire for integration, lest your sense of opportunity turns into extreme opportunism. Here also, the key to success lies in a correct estimate of everyone's chances and possibilities. Although management is one of your forte, and you can adjust your objectives to current realities better than other people, you lack the hindsight which enables you to avoid short-term vagaries and daily fluctuations. If you strive too much to adapt, you run a risk of betraying yourself. This is the other traditional side of the coin with "The Greater Benefic"!

Interpretation of the 11° Pisces symbolic degree

"A young man in a nice suit stands between two cones and fiddles with his wristwatch. One of the cones is intact, and the other one has its top cut off." (Janduz version)

Indecisive, anxious, and ambitious character. If one is born in a wealthy family, after a reversal of fortune, one strives to recover one's social status. If one has modest origins, one is capable to rise to an important position and to achieve some degree of fame. In both cases, one must not aim at the top since this degree indicates limitations, and any attempt to reach the summit results in accidents or health conditions.

Saturn in Scorpio

The planet Saturn symbolizes contraction, effort, time, limitation and concentration. Saturn eliminates anything that is not authentic, sooner or later. It is impossible to cheat him as he gives an irresistible desire to form a coherent whole with oneself, in responsible and wise ways. He is the great purifier. He represents our limitations but also our truth. In your natal chart, the house position where Saturn is posited is more important than his sign position because, like Jupiter, Uranus, Neptune and Pluto, he is a slow planet. Many people born in the same period have Saturn in the same sign. This is the reason why the sign occupied here is less meaningful than when it is occupied by the so-called fast planets, i.e. the Sun, the Moon, Mercury, Venus and Mars. Therefore, some caution is to be exercised as you read what follows. Saturn in Scorpio reinforces your resistance. Your demand for precision and your will to comprehend all things may make you seem a bit tough or harsh to your entourage. Because you are fond of precision, you are interested in exact sciences; your capacity to understand mysteries is strengthened. You learn to control your instincts, even though it may be detrimental to your spontaneity.

Saturn Dominant

If Saturn is part of your natal chart's planetary dominants, in astrology, you are said to be a Saturnian: you gladly leave to other people the decision to take life as it comes. As far as you are concerned, you prefer to take advantage of your experiences in order to discover, to grow, and to question yourself.

Interpretation of the 20° Scorpio symbolic degree

"At the top of a hillock, a bull paws the ground violently. In the field below, a horse gallops freely." (Janduz version)

Tenacious, passionate, and agile character. Since one cannot bear any form of constraint, one is determined to struggle for freedom, one's own as well as that of other people. Youth is plagued by hardships, but the sufferings undergone in early life turn into a powerful spur to later become a brilliant champion of law and social reforms. One may also be an excellent acrobat.

Uranus 19°51' Aquarius

Uranus Aspects
Saturn square Uranus orb -0°10'
Mars sextile Uranus orb -2°34'
Planets: Uranus

Uranus represents individual freedom, originality, independence, marginality, avant guard inspiration, ultra modernism. Fire is its element, it is dry, and it rules Aquarius, is in exaltation with Scorpio and is in analogy with the brain and the nerves.

It represents inventors, odd characters, revolutionaries.

Temperament : Nervous to the extreme

Characterology : Emotive, Active, Secondary type; it is a Passionate type.

Uranus in Aquarius

The planet Uranus symbolizes originality, independence and cerebral energy bursting suddenly. Uranus triggers the irresistible need for freedom that we have in ourselves. Uranus tends to break the constraints that have become unbearable and gives us the courage and the will to get rid of what has become a burden; when he is well aspected, he also indicates genius. In your natal chart, Uranus’ house position is more important than his sign position because, like Jupiter, Saturn, Neptune and Pluto, he is a slow planet. Many people born in the same period have Uranus in the same sign. This is the reason why the sign occupied here is less meaningful than when it is occupied by the so-called fast planets, i.e. the Sun, the Moon, Mercury, Venus and Mars. Therefore, some caution is to be exercised as you read what follows. The sign positions of Uranus, Neptune and Pluto have a collective meaning. They do not influence your personality, unless they are involved in numerous aspects or when they emphasize a personal point of your natal chart such as your Ascendant’s ruler, an angular planet, i.e. a planet near the Ascendant, the Midheaven, the Nadir or the Descendant. In such cases, the activity of the slow planet is very highlighted. Uranus in Aquarius is in his own sign and, according to the Tradition, he is most potent and at his best: you are freedom-oriented and your desire to revolutionize the world in your fields of interest is irresistible. You are attracted by avant-gardist areas such as higher technologies, astrology etc…

Uranus Dominant

If Uranus is part of your natal chart's planetary dominants, in astrology, you are said to be a Uranian: personal values are prevailing. Inner certainties fuel an inflexible will and a desire to call attention on yourself as well as to follow your beliefs through. This planet prompts you to behave with determination, to put forward your own truth, and to start your personal revolution. More than other people, you are willing to keep some degree of autonomy in all circumstances, and you often display an individualistic nature. In order to achieve your ideal of freedom and independence, you may act like a despot as you try to convince and to impose your views, whether smoothly or forcefully. Regardless of the flexibility of your comportment, some situations demand an absolute firmness as well as uncompromising, frank and straightforward attitudes. People may criticise you for your intransigence and say that you are a hardliner. Outsider's opinions don't matter! The most important thing is that you act in all conscience and reach your primary objectives. More than anyone else, you know how to use your willpower and to focus your energy on a precise aim, relentlessly, whatever the consequences might be. In the chapter of qualities, let's mention a definite sense of responsibility, an innovative mind open to techniques and modern ideas, as well as a natural self-discipline which overcomes many an obstacle. Therefore, people are well-advised not to hound you into a corner.

Interpretation of the 19° Aquarius symbolic degree

"In the street, a man shows a newspaper featuring Human Rights on the front page. A priest preaches in a church." (Janduz version)

Hard-working, withdrawn, and altruistic character. After a few ordeals, one achieves a wealthy and independent position in religion or humanitarian work owing to one's merits and dedication to the public good. One readily lends assistance to people and, as a result, one receives providential assistance. This degree indicates longevity and professional changes rewarded by success and security.

Neptune Aspects

Saturn trine Neptune orb -2°37'
Mars inconjunction Neptune orb -0°14'
Moon semi-square Neptune orb +1°21'
Planets: Neptune

Neptune represents escapism, impressionability, daydreaming, delusions, carelessness, deception or intuition, dishonesty or inspiration, telepathy. Water is its element, it is moist, it rules Pisces, is in exaltation in Cancer, though some authors say it is Leo, and is in analogy with the vegetative system.

It represents dreamers, mediums, magicians, merchants of illusion, drug addicts.

Temperament : rather Lymphatic

Characterology : Emotive, non Active, Primary or Secondary type; it is a Sentimental, or sometimes Amorphous type.

Neptune in Cancer

The planet Neptune symbolizes extreme receptivity, intense emotional sharpness, impressionability and inspiration; it is the planet of mediums, mystics and religious faith. In an astrological chart, it indicates dilution, vagueness, understanding one’s environment through emotions and the absence of clear and determined limits and structures. In your natal chart, Neptune’s house position is more important than his sign position because, like Jupiter, Saturn, Uranus and Pluto, he is a slow planet. Many people born in the same period have Neptune in the same sign. This is the reason why the sign occupied here is less meaningful than when it is occupied by the so-called fast planets, i.e. the Sun, the Moon, Mercury, Venus and Mars. Therefore, some caution is to be exercised as you read what follows. The sign positions of Uranus, Neptune and Pluto have a collective meaning. They do not influence your personality, unless they are involved in numerous aspects or when they emphasize a personal point of your natal chart such as your Ascendant’s ruler, an angular planet, i.e. a planet near the Ascendant, the Midheaven, the Nadir or the Descendant. In such cases, the activity of the slow planet is very highlighted. Neptune in Cancer increases tenfold your emotionalism and your natural nostalgia. Your musings are huge and fruitful. You are inspired and supported by your feelings. Your inner life is splendid.

Neptune Dominant

If Neptune is part of your natal chart's planetary dominants, in astrology, you are said to be a Neptunian: your intuition is highly developed. You are of a contemplative nature, and you are particularly receptive to ambiances, places, and people. You gladly cultivate the art of letting-go, and you allow the natural unfolding of events to construct your world. You follow your inspirations, for better or for worse. At times, you display an extraordinary clairvoyance gift. You seem to be able to read your subconscious like a book, and you track down subtle underlying mechanisms, flaws, or open breaches. This innate intuition might explain the strokes of good luck which the Neptunian is sometimes credited with. However, you may also be the victim of illusions and misleading intuitions. You are an idealist, and you let your deepest aspirations prevail over the realities of the moment. Then, you set off in quest of some quixotic objective, living like a Don Quixote who relentlessly pursues an impossible dream. You have a great talent for psychology and the mysteries of the human soul. Since you instinctively perceive people's intents and motivations, as you swim in the complexity of human nature, you feel in your element. The subtlety of your perceptiveness is the source of both special affections and irrevocable rejections. What is the danger of such a dominant? If it is not offset by other influences in your natal chart, you may not have an iron will. Your trump card is your instinct, which may be developed to the extent that it becomes clairvoyance.

Interpretation of the 22° Cancer symbolic degree

"A man sleeps in a field, in broad daylight, near another man who yawns and stretches himself, while two marauders steal their working tools." (Janduz version)

Carefree, neglectful, and lazy character. Nevertheless, owing to sheer good luck, brilliant success and happiness are achieved around mid-life. One must then put up every effort in order to make them last, because otherwise, one is most likely to end up in poverty and loneliness.

Pluto 1°44' Я Sagittarius

Pluto Aspects
Sun trine Pluto orb +1°15'
Moon opposite Pluto orb -4°33'
Mercury trine Pluto orb -8°10'
Planets: Pluto

Pluto represents deep transformations, mutations and eliminations, sexuality and magnetism, power and secrets, destruction with a view to regeneration, the phoenix rising from the ashes. Its element is indefinite; burning (like lava in fusion ?), it rules Scorpio, is in exaltation in Pisces and is in analogy with the sexual organs and excretion.

It represents dictators, sadistic people, violent characters, is instinctive and powerful but also mysterious with hidden strengths.

Temperament : rather Bilious

Characterology : Emotive or non-Emotive, Active, Primary type; it is a Passionate Choleri typec.

Pluto in Sagittarius

The planet Pluto symbolizes deep disruptions and upheavals, domination and sexual instincts, and the inner power we have in ourselves. Pluto destroys in order to reconstruct and he provokes painful crises that are needed in metamorphosis. Pluto is our deepest instincts’ brutal force. It is the hidden and unconscious violence that can explode in us with incredible intensity before being projected in our actions; in itself, the planet is not negative: the might and the intensity of its energy are beyond the conceivable but it can be funnelled. Pluto is the only possibility we have at our disposal to overcome our inner blocks and to eliminate outgrown situations that have become inextricable. Pluto’s energy is valuable because of its usefulness for the irreversible destruction of what constitutes a problem and not because of its negative side and its perversity. Pluto allows to reconstruct and to regenerate parts of our personality or whole stretches of our life, provided that we manage to funnel his wild energy and to step back. It is impossible to tame this energy, given its essence. However, it is possible to take advantage of it for a precise aim, through a temporary identification of some parts of us with this energy. In such a case, the outcome is our final evolution and even, our transformation. In your natal chart, Pluto’s house position is more important than his sign position because, like Jupiter, Saturn, Uranus and Neptune, Pluto is a slow planet. Many people born in the same period have Pluto in the same sign. This is the reason why the sign occupied here is less meaningful than when it is occupied by the so-called fast planets, i.e. the Sun, the Moon, Mercury, Venus and Mars. Therefore, some caution is to be exercised as you read what follows. The sign positions of Uranus, Neptune and Pluto have a collective meaning. They do not influence your personality and they are not to be really taken into account, unless they are involved in numerous aspects or when they emphasize a personal point of your natal chart such as your Ascendant’s ruler, an angular planet, i.e. a planet near the Ascendant, the Midheaven, the Nadir or the Descendant. In such cases, the activity of the slow planet is very highlighted. Pluto in Sagittarius prompts you to discover and to conquer. Your appetite for power may be satisfied abroad.

Pluto Dominant

If Pluto is part of your natal chart's planetary dominants, in astrology, you are said to be a Plutonian: you sometimes feel like a foreigner who does not belong to the world, to its laws, and its concerns. The rules of life in society are not necessarily yours. You are interested in what is unknown and in the subtle laws of a hidden order. So, you take malicious pleasure in ridiculing the patterns you find too simplistic or too rigid. You also revel in underlining the limits of explanations you deem too common. There is something unconventional about the way you are, the way you think, and the way you act. What is your specificity made of? Is it an extraordinary partner? A life off the beaten path? Or do you only distance yourself from conventional morals? In any case, you have the feeling, sometimes quite vague, that you come from nowhere, and that you do not belong to any definite group... In short, it means that you cannot be simplified in order to conform to existing models. The gap between you and ordinary mortals is also an element of your strength. Your deep clear-sightedness, firstly, enables you to put things into perspective and to grant them only the attention they deserve. Your other remarkable asset is your capacity to intervene from behind the scenes, to secretly organise events, and to bring about the desirable outcome without seeming to impose or to dictate anything. However, you must still overcome one of the major difficulties of this dominant, which is to get people to accept your difference and to smoothly fit into your environment.

Interpretation of the 1° Sagittarius symbolic degree

"A man in uniform brandishes a sword while a child shoots stones with a catapult." (Janduz version)

Authoritarian, quarrelsome, and stubborn character. The natural aggressiveness must be canalised in an occupation requiring a great deal of energy and stamina such as the military, the Bar, or any sport. One may be involved in numerous lawsuits.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

Chiron 15°23' Я Libra
Asteroids: Chiron

Chiron is almost renowned and used everywhere. Most astrologers consider it as a kind of "mediator" between Saturn and outer planets. Consequently, Chiron is of Saturn's nature and at the same time is influenced by Uranus, the first slow-moving planet. Astrologically, it symbolizes wisdom, patience and the faculty to reduce others' sufferings: it is said to be the "great healer" of the zodiac. Like all the secondary bodies, it must be in close conjunction with planets or angles in order to fully express its action.

Interpretation of the 15° Libra symbolic degree

"A man walks between two women with arms entwined." (Janduz version)

Cheerful, caring, but frivolous character prone to self-leniency and fickleness. Romance and marriage are most likely to be the sources of setbacks and misfortunes. However, should the natal chart concur, this degree may describe a loving heart and a long-lasting happiness shared with one's soul mate.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

Asteroids: Ceres

Ceres, the biggest of the four minor asteroids used besides Chiron, is associated with the mythological goddess of growing plants and harvest and also symbolizes physical constitution, vitality and fertility. She's also known as Demeter, according to the astrologer Zipporah Dobyns, linked to the symbolism of the mother but in a less emotive and more physical way than the Moon. Ceres is thought to be the ruler of Virgo, in exaltation in Gemini, in exile in Pisces and in fall in Sagittarius. Keywords associated with Ceres could be order, practical sense, worry, precision, modesty, method, sobriety, motherhood, fertility, the Earth: a kind of a more cerebral Moon...

Asteroids: Pallas

Pallas is sometimes used in modern Astrology: she represents intelligence, abstract and global thinking talents. It is usually considered to be a determining element in political strategy.

Asteroids: Juno

Juno is the asteroid corresponding to the adaptation to the marital partner and to the defence of individual rights; it is thus used in the field of marriage.

Asteroids: Vesta

Vesta is rarely used and brings the ability to efficiently devote oneself to a cause.

True North Node 26°05' Я Capricorn
North Node

The North Node (True Node here) represents the goals that must be achieved during life, in the karmic sense according to some traditions. Its position in house indicates in what field an effort is necessary in order to evolve. The North Node is often called the Dragon's head, it is usually considered beneficial, a bit like Jupiter with the planets. The Lunar nodes are fictional points and not actual heavenly bodies: they are the intersections of the Moon with the Ecliptic (the path made by the Sun in its orbit as seen from the Earth). The axis of the Lunar nodes moves 19 degrees each year, namely a bit more than three minutes each day.

The South Node is diametrically opposed to the North Node, therefore it faces it (it's not drawn here, it's the same symbol but upside down). It symbolizes what has already been achieved or acquired, in a karmic sense: it's the past from which it's advised to move on in order to progress. The South Node is rather negative, of a Saturnian nature: the experience through suffering.

Interpretation of the 26° Capricorn symbolic degree

"A man walks at the edge of the forest towards a modest house surrounded by a vine stock." (Janduz version)

Withdrawn, enduring, and honest character. One revels in solitude and quiet activities such as reading and writing. Although one is very skilful in one's field of competence, one is unwilling to compete with others and contents oneself with a simple life devoid of conflicts.

N.B.: symbolic degrees belong to a branch of fatalistic astrology. Their interpretation must be regarded with the utmost caution, especially given the fact that different authors give different meanings to symbolic degrees. This is the reason why they are not included in our Astrotheme reports.

True Lilith 20°36' Я Leo

Lilith or the Dark Moon (True Lilith here) represents the uncrossable threshold, taboos, the individual's provocative and fascinating side, including on a sexual level. She symbolizes violence and "untameability", the radical and deep-seated refusal to submit. The keywords for Lilith can be sterility, sadism, perversity, castration, sadomasochism, eroticism, orgasm, forbidden fantasies, marginality, cruelty; redemption, illumination, rebelliousness... Lilith's opposite point is called Priapus; it is the Lunar perigee, the position where the Moon is closest to the Earth. It symbolizes man's primitive nature, the horror hidden in our deepest self; masochism, extreme sensuality, impulsiveness, irrationality and excess. Physically speaking, the Dark Moon is the focal point unoccupied by the Earth: it is not a concrete body but a mathematical point.

Interpretation of the 20° Leo symbolic degree

"A man emerging from the mist holds a key in one hand and raises the other hand towards a moon-shaped face, above which a snake sleeps." (Janduz version)

Compassionate, diplomatic, and far-sighted character. The sleeping snake symbolises introspection, penetrating intelligence, as well as wisdom. The raised hand calls attention upon the great mysteries of life. Success can be achieved in human sciences, mathematics, astronomy, or any intellectual pursuit requiring method and riddle-solving talents.

The Part of Fortune is an ancient concept, used by Ptolemy and other astrologers before him. Firstly, it has nothing to do with fortune! In modern astrology, it is actually used to enhance a planet or angle when in close conjunction with it: it thus amplifies the meaning associated to the point affected by its presence. It is calculated in the following way:

Part of Fortune = AS + Moon - Sun (it is the Moons position when the Sun rises)

The classical Part of Fortune, of which the calculus method is unchanged whether in a diurnal or nocturnal chart, is usually distinguished from the diurnal/nocturnal Part of Fortune which is calculated by the formula AS + Sun - Moon for a nocturnal chart, and AS + Moon - Sun in a diurnal chart.

We currently use the latter formula for our astrological programmes.

Ascendant or House I

The First House or Ascendant represents one's behaviour in the eyes of others, and also one's health. It corresponds to the way the individual acts in the world. It is the image of the personality seen by others and the person's visible behaviour expressed outwardly. The 1st House is in analogy with Aries and thus Mars too, and then the Sun. It is an angular house, the most important one with the Midheaven, maybe even more so due to its link with the body and health.

Midheaven or House X

The Tenth House still called the Midheaven, is the highest point amidst the houses, at the top of the chart, in the South, and relates to destiny in general and career (and not daily work as meant by the Sixth House). The Midheaven represents our achievements and goals in the social sphere, our social position in society, and becomes more and more important as we get older. It is in analogy with Capricorn and Saturn. The Tenth House is the most important angular house along with the Ascendant.

House I (AC)

The First House or Ascendant represents one's behaviour in the eyes of others and also one's health. It corresponds to the way the individual acts in the world. It is the image of the personality as seen by others and the person's visible behaviour expressed outwardly. The 1st House is in analogy with Aries and thus Mars too and then the Sun. It is an angular house, the most important one with the Midheaven, maybe even more so due to its link with the body and health; the Ascendant is as important as the Sun in a natal chart.

House II

The Second House is the sphere of material security, the money we earn, our possessions, also in a symbolic meaning (close people etc). It is in analogy with Taurus and Venus. It is a succedent house, quite important.

House III

The Third House is the sphere of social and intellectual apprenticeship, studies, relationships with close people and surroundings, short trips, light-hearted and quick contacts, correspondences. It is in analogy with Gemini and Mercury. It's a cadent house, less important than the angular and succedent ones.

House IV (IC)

The Fourth House also called Immum Coeli is the sphere of inner emotions, family, the father, home and roots, but also the home one creates. It's Home Sweet Home, security and cocoon. It is in analogy with Cancer and the Moon. It's an angular and important house.

House V

The Fifth House is the sphere of pleasures and love affairs (but not commitment or marriage), creations and entertainments, children, arts and game. It is in analogy with Leo and the Sun. It's a succedent and quite important house.

House VI

The Sixth House is the sphere of apprenticeship and effort in the work environment, daily life, health on a daily basis and not operations or long-term diseases, relationships with co-workers or subordinates, desire for improvement, analysis and detail. It is in analogy with Virgo and Mercury. It is a cadent house, less important than the angular and succedent ones.

House VII (DS)

The Seventh House also called the Descendant (in front of the Ascendant) is the sphere of partnership, marriage, contracts, relationships with others, the outer world. It is in analogy with Libra and Venus, and Saturn to a lesser extent. It is an angular and important house.

House VIII

The Eighth House is the sphere of emotional security, the depths of the self, secrets and paranormal, transcendence, sexuality, mysteries, upheavals, surgical operations, others' money (investments, inheritances), crises, transformation after evolution, death. It is in analogy with Scorpio and Pluto, and Mars to a lesser extent. It is a succedent and quite important house.

House IX

The Ninth House is the sphere of high studies, both physical and mental journeys (philosophy, spirituality), rebelliousness, changes of scenery, desire for dealing with the unknown. It is in analogy with Sagittarius and Jupiter. It is a cadent house, less important than the angular and succedent ones.

House X (MC)

The Tenth House still called the Midheaven, is the highest point amidst the houses, at the top of the chart, in the South, and relates to destiny in general and career (and not daily work as meant by the Sixth House). The Midheaven represents our achievements and goals in the social sphere, our social position in society, and becomes more and more important as we get older. It is in analogy with Capricorn and Saturn. The Tenth House is the most important angular house along with the Ascendant.

House XI

The Eleventh House is the sphere of friendship and protection, projects, search for social acceptance and security, collective and humanitarian actions. It is in analogy with Aquarius and Uranus, and Saturn to a lesser extent. It's a succedent and quite important house.

House XII

The Twelfth House is the sphere of hidden things, enemies, closed or remote places (hospital, prison, convent etc.), ordeals, secrecy, solitude, long-term illnesses but also sincere devotion and genuine compassion. It is in analogy with Pisces and Neptune.

Biography of Pierre-Simon Laplace

Pierre-Simon, marquis de Laplace (March 23, 1749 - March 5, 1827) was a French mathematician and astronomer whose work was pivotal to the development of mathematical astronomy. He summarized and extended the work of his predecessors in his five volume Mécanique Céleste (Celestial Mechanics) (1799-1825). This seminal work translated the geometric study of classical mechanics, used by Isaac Newton, to one based on calculus, opening up a broader range of problems.

He formulated Laplace's equation, and invented the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. The Laplacian differential operator, widely used in applied mathematics, is also named after him.

He restated and developed the nebular hypothesis of the origin of the solar system and was one of the first scientists to postulate the existence of black holes and the notion of gravitational collapse.

He is remembered as one of the greatest scientists of all time, sometimes referred to as a French Newton or Newton of France, with a natural phenomenal mathematical faculty possessed by none of his contemporaries.

He became a count of the First French Empire in 1806 and was named a marquis in 1817, after the Bourbon Restoration.

Early life
Unfortunately, many details of the life of Laplace were lost when the family château burned in 1925.

Laplace was born in Beaumont-en-Auge, Normandy in 1749.

According to W. W. Rouse Ball (A Short Account of the History of Mathematics, 4th edition, 1908), he was the son of a small cottager or perhaps a farm-labourer, and owed his education to the interest excited in some wealthy neighbours by his abilities and engaging presence. Very little is known of his early years, for when he became distinguished he had the pettiness to hold himself aloof both from his relatives and from those who had assisted him. It would seem from a pupil he became an usher in the school at Beaumont; but, having procured a letter of introduction to d'Alembert, he went to Paris to push his fortune. However, Karl Pearson is scathing about the inaccuracies in Rouse Ball's account and states,

Indeed Caen was probably in Laplace's day the most intellectually active of all the towns of Normandy. It was here that Laplace was educated and was provisionally a professor. It was here he wrote his first paper published in the Mélanges of the Royal Society of Turin, Tome iv. 1766-1769, at least two years before he went at 22 or 23 to Paris in 1771. Thus before he was 20 he was in touch with Lagrange in Turin. He did not go to Paris a raw self-taught country lad with only a peasant background! In 1765 at the age of sixteen Laplace left the "School of the Duke of Orleans" in Beaumont and went to the University of Caen, where he appears to have studied for five years. The 'Ecole militaire' of Beaumont did not replace the old school until 1776.

His parents were from comfortable families. His father was Pierre Laplace, and his mother was Marie-Anne Sochon. The Laplace family were involved in agriculture until at least 1750, but Pierre Laplace senior was also a cider merchant and syndic of the town of Beaumont. Pierre Simon Laplace attended a school in the village run at a Benedictine priory, his father intending that he would be ordained in the Roman Catholic Church, and at sixteen he was sent to further his father's intention at the University of Caen, reading theology.

At the university, he was mentored by two enthusiastic teachers of mathematics, Christophe Gadbled and Pierre Le Canu, who awoke his zeal for the subject. Laplace never graduated in theology but left for Paris with a letter of introduction from Le Canu to Jean le Rond d'Alembert. According to his great-great-grandson, d'Alembert received him rather poorly, and to get rid of him gave him a thick mathematics book, saying to come back when he had read it. When Laplace came back a few days later, d'Alembert was even less friendly and didn't hide his opinion that it was impossible that Laplace could have read and understood the book. But upon questioning him, he realized that it was true, and from that time he took Laplace under his care. Another version is that Laplace solved overnight a problem that d'Alembert set him for submission the following week, then solved a harder problem the following night. D'Alembert was impressed and recommended him for a teaching place in the École Militaire.

With a secure income and undemanding teaching, Laplace now threw himself into original research and, in the next seventeen years, 1771-1787, he produced much of his original work in astronomy.

Laplace further impressed the Marquis de Condorcet, and even in 1771 Laplace felt that he was entitled to membership in the French Academy of Sciences. However, in that year, admission went to Alexandre-Théophile Vandermonde and in 1772 to Jacques Antoine Joseph Cousin. Laplace was disgruntled, and at the beginning of 1773, d'Alembert wrote to Lagrange in Berlin to ask if a postion could be found for Laplace there. However, Condorcet became permanent secretary of the Académie in February and Laplace was elected associate member on 31 March, at age 24.

He married Marie-Charlotte de Courty de Romanges in his late thirties and the couple had a daughter, Sophie, and a son, Charles-Émile (b. 1789).

Analysis, probability and astronomical stability
Laplace's early published work in 1771 started with differential equations and finite differences but he was already starting to think about the mathematical and philosophical concepts of probability and statistics. However, before his election to the Académie in 1773, he had already drafted two papers that would establish his reputation. The first, Mémoire sur la probabilité des causes par les événements was ultimately published in 1774 while the second paper, published in 1776, further elaborated his statistical thinking and also began his systematic work on celestial mechanics and the stability of the solar system. The two disciplines would always be interlinked in his mind. "Laplace took probability as an instrument for repairing defects in knowledge." Laplace's work on probability and statistics is discussed below with his mature work on the Analytic theory of probabilities.

Stability of the solar system
Sir Isaac Newton had published his Philosophiae Naturalis Principia Mathematica in 1687 in which he gave a derivation of Kepler's laws, which describe the motion of the planets, from his laws of motion and his law of universal gravitation. However, though Newton had privately developed the methods of calculus, all his published work used cumbersome geometric reasoning, unsuitable to account for the more subtle higher-order effects of interactions between the planets. Newton himself had doubted the possibility of a mathematical solution to the whole, even concluding that periodic divine intervention was necessary to guarantee the stability of the solar system. Dispensing with the hypothesis of divine intervention would be a major activity of Laplace's scientific life. It is now generally regarded that Laplace's methods on their own, though critical to the development of the theory, are not sufficiently precise to demonstrate the stability of the Solar System, and indeed, the Solar System is now understood to be chaotic, although in practice fairly stable.

One particular problem from observational astronomy was the apparent instability whereby Jupiter's orbit appeared to be shrinking while that of Saturn was expanding. The problem had been tackled by Leonhard Euler in 1748 and Joseph Louis Lagrange in 1763 but without success. In 1776, Laplace published a memoir in which he first explored the possible influences of a purported luminiferous ether or of a law of gravitation that did not act instantaneously. He ultimately returned to an intellectual investment in Newtonian gravity. Euler and Lagrange had made a practical approximation by ignoring small terms in the equations of motion. Laplace noted that though the terms themselves were small, when integrated over time they could become important. Laplace carried his analysis into the higher-order terms, up to and including the cubic. Using this more exact analysis, Laplace concluded that any two planets and the sun must be in mutual equilibrium and thereby launched his work on the stability of the solar system. Gerald James Whitrow described the achievement as "the most important advance in physical astronomy since Newton".

Laplace had a wide knowledge of all sciences and dominated all discussions in the Académie. Laplace seems to have regarded analysis merely as a means of attacking physical problems, though the ability with which he invented the necessary analysis is almost phenomenal. As long as his results were true he took but little trouble to explain the steps by which he arrived at them; he never studied elegance or symmetry in his processes, and it was sufficient for him if he could by any means solve the particular question he was discussing.

On the figure of the Earth
During the years 1784-1787 he published some memoirs of exceptional power. Prominent among these is one read in 1783, reprinted as Part II of Théorie du Mouvement et de la figure elliptique des planètes in 1784, and in the third volume of the Méchanique céleste. In this work, Laplace completely determined the attraction of a spheroid on a particle outside it. This is memorable for the introduction into analysis of spherical harmonics or Laplace's coefficients, and also for the development of the use of the potential, a name first used by George Green in 1828.

Spherical harmonics

In 1783, in a paper sent to the Académie, Adrien-Marie Legendre had introduced what are now known as associated Legendre functions. If two points in a plane have polar co-ordinates (r, θ) and (r ', θ'), where r ' ≥ r, then, by elementary manipulation, the reciprocal of the distance between the points, d, can be written as:

This expression can be expanded in powers of r/r ' using Newton's generalized binomial theorem to give:

The sequence of functions P0k(cosф) is the set of so-called "associated Legendre functions" and their usefulness arises from the fact that every function of the points on a circle can be expanded as a series of them.

Laplace, with scant regard for credit to Legendre, made the non-trivial extension of the result to three dimensions to yield a more general set of functions, the spherical harmonics or Laplace coefficients. The latter term is not now in common use. Every function of the points on a sphere can be expanded as a series of them.

Potential theory
This paper is also remarkable for the development of the idea of the scalar potential. The gravitational force acting on a body is, in modern language, a vector, having magnitude and direction. A potential function is a scalar function that defines how the vectors will behave. A scalar function is computationally and conceptually easier to deal with than a vector function.

Alexis Clairault had first suggested the idea in 1743 while working on a similar problem though he was using Newtonian-type geometric reasoning. Laplace described Clairault's work as being "in the class of the most beautiful mathematical productions". However, Rouse Ball alleges that the idea "was appropriated from Joseph Louis Lagrange, who had used it in his memoirs of 1773, 1777 and 1780".

Laplace applied the language of calculus to the potential function and shows that it always satisfies the differential equation:

- and on this result his subsequent work on gravitational attraction was based. The quantity has been termed the concentration of and its value at any point indicates the "excess" of the value of there over its mean value in the neighbourhood of the point. Laplace's equation, a special case of Poisson's equation, appears ubiquitously in mathematical physics. The concept of a potential occurs in fluid dynamics, electromagnetism and other areas. Rouse Ball speculated that it might be seen as "the outward sign" of one the "prior forms" in Kant's theory of perception.

The spherical harmonics turn out to be critical to practical solutions of Laplace's equation. Laplace's equation in spherical coordinates, such as are used for mapping the sky, can be simplified, using the method of separation of variables into a radial part, depending solely on distance from the centre point, and an angular or spherical part. The solution to the spherical part of the equation can be expressed as a series of Laplace's spherical harmonics, simplifying practical computation.

Planetary inequalities
This memoir was followed by another on planetary inequalities, which was presented in three sections in 1784, 1785, and 1786. This deals mainly with the explanation of the "great inequality" of Jupiter and Saturn. Laplace showed by general considerations that the mutual action of two planets could never largely affect the eccentricities and inclinations of their orbits; and that the peculiarities of the Jovian system were due to the near approach to commensurability of the mean motions of Jupiter and Saturn: further developments of these theorems on planetary motion were given in his two memoirs of 1788 and 1789. It was on these data that Delambre computed his astronomical tables.

It had been observed that since ancient times the Moon's overall orbital speed was changing over time. In 1693, Edmond Halley had shown that the rate of the drift in position was increasing, an effect known as the secular acceleration of the Moon. Laplace gave an explanation in 1787 in terms of changes in the eccentricity of the Earth's orbit. However, in 1853, John Couch Adams went on to show that Laplace had only considered the radial force on the moon and not the tangential, and hence had failed to explain more than half of the drift. The other half was subsequently shown to be due to tidal acceleration. However, Laplace was still able to use his result to complete his "proof" of the stability of the whole solar system on the assumption that it consists of a collection of rigid bodies moving in a vacuum.

All the memoirs above alluded to were presented to the Académie des sciences, and they are printed in the Mémoires présentés par divers savants.

Celestial mechanics
Classical mechanics

Newton's Second Law

Laplace now set himself the task to write a work which should "offer a complete solution of the great mechanical problem presented by the solar system, and bring theory to coincide so closely with observation that empirical equations should no longer find a place in astronomical tables." The result is embodied in the Exposition du système du monde and the Mécanique céleste.

The former was published in 1796, and gives a general explanation of the phenomena, but omits all details. It contains a summary of the history of astronomy. This summary procured for its author the honour of admission to the forty of the French Academy and is commonly esteemed one of the masterpieces of French literature, though it is not altogether reliable for the later periods of which it treats.

Laplace developed the nebular hypothesis of the formation of the solar system, first suggested by Emanuel Swedenborg and expanded by Immanuel Kant, a hypothesis that continues to dominate accounts of the origin of planetary systems. According to Laplace's description of the hypothesis, the solar system had evolved from a globular mass of incandescent gas rotating around an axis through its centre of mass. As it cooled this mass contracted and successive rings broke off from its outer edge. These rings in their turn cooled, and finally condensed into the planets, while the sun represented the central core which was still left. On this view Laplace predicted that the more distant planets would be older than those nearer the sun.

As mentioned, the idea of the nebular hypothesis had been outlined by Immanuel Kant in 1755, and he had also suggested "meteoric aggregations" and tidal friction as causes affecting the formation of the solar system. Laplace was probably aware of this, but, like many writers of his time, he generally did not reference the work of others.

Laplace's analytical discussion of the solar system is given in his Méchanique céleste published in five volumes. The first two volumes, published in 1799, contain methods for calculating the motions of the planets, determining their figures, and resolving tidal problems. The third and fourth volumes, published in 1802 and 1805, contain applications of these methods, and several astronomical tables. The fifth volume, published in 1825, is mainly historical, but it gives as appendices the results of Laplace's latest researches. Laplace's own investigations embodied in it are so numerous and valuable that it is regrettable to have to add that many results are appropriated from other writers with scanty or no acknowledgement, and the conclusions - which have been described as the organized result of a century of patient toil - are frequently mentioned as if they were due to Laplace.

Jean-Baptiste Biot, who assisted Laplace in revising it for the press, says that Laplace himself was frequently unable to recover the details in the chain of reasoning, and, if satisfied that the conclusions were correct, he was content to insert the constantly recurring formula, "Il est aisé à voir que..." ("It is easy to see that..."). The Mécanique céleste is not only the translation of Newton's Principia into the language of the differential calculus, but it completes parts of which Newton had been unable to fill in the details. The work was carried forward in a more finely tuned form in Félix Tisserand's Traité de mécanique céleste (1889-1896), but Laplace's treatise will always remain a standard authority.

Main article: Society of Arcueil
In 1806, Laplace bought a house in Arcueil, then a village and not yet absorbed into the Paris conurbation. Claude Louis Berthollet was a near neighbour and the pair formed the nucleus of an informal scientific circle, latterly known as the Society of Arcueil. Because of Laplace and Berthollet's closeness to Napoleon, they effectively controlled advancement in the scientific establishment and admission to the more prestigious offices. The Society built up a complex pyramid of patronage.

Laplace and Napoleon
An account of a famous interaction between Laplace and Napoleon is provided by Rouse Ball:

"Laplace went in state to beg Napoleon to accept a copy of his work, and the following account of the interview is well authenticated, and so characteristic of all the parties concerned that I quote it in full. Someone had told Napoleon that the book contained no mention of the name of God; Napoleon, who was fond of putting embarrassing questions, received it with the remark, 'M. Laplace, they tell me you have written this large book on the system of the universe, and have never even mentioned its Creator.' Laplace, who, though the most supple of politicians, was as stiff as a martyr on every point of his philosophy, drew himself up and answered bluntly, 'Je n'avais pas besoin de cette hypothèse-là.' 'Napoleon, greatly amused, told this reply to Lagrange, who exclaimed, 'Ah! c'est une belle hypothèse; ça explique beaucoup de choses.' "

Black holes
Laplace also came close to propounding the concept of the black hole. He pointed out that there could be massive stars whose gravity is so great that not even light could escape from their surface (see escape velocity). Laplace also speculated that some of the nebulae revealed by telescopes may not be part of the Milky Way and might actually be galaxies themselves. Thus, he anticipated the major discovery of Edwin Hubble, some 100 years before it happened.

Analytic theory of probabilities
In 1812, Laplace issued his Théorie analytique des probabilités in which he laid down many fundamental results in statistics. In 1819, he published a popular account of his work on probability. This book bears the same relation to the Théorie des probabilités that the Système du monde does to the Méchanique céleste.

Probability-generating function
The method of estimating the ratio of the number of favourable cases, compared to the whole number of possible cases, had been previously indicated by Laplace in a paper written in 1779. It consists of treating the successive values of any function as the coefficients in the expansion of another function, with reference to a different variable. The latter is therefore called the probability-generating function of the former. Laplace then shows how, by means of interpolation, these coefficients may be determined from the generating function. Next he attacks the converse problem, and from the coefficients he finds the generating function; this is effected by the solution of a finite difference equation.

Least squares
This treatise includes an exposition of the method of least squares, a remarkable testimony to Laplace's command over the processes of analysis. The method of least squares for the combination of numerous observations had been given empirically by Carl Friedrich Gauss (around 1794) and Legendre (in 1805), but the fourth chapter of this work contains a formal proof of it, on which the whole of the theory of errors has been since based. This was affected only by a most intricate analysis specially invented for the purpose, but the form in which it is presented is so meagre and unsatisfactory that, in spite of the uniform accuracy of the results, it was at one time questioned whether Laplace had actually gone through the difficult work he so briefly and often incorrectly indicates.

Inductive probability

While he conducted much research in physics, another major theme of his life's endeavours was probability theory. In his Essai philosophique sur les probabilités (1814), Laplace set out a mathematical system of inductive reasoning based on probability, which we would today recognise as Bayesian. One well-known formula arising from his system is the rule of succession. Suppose that some trial has only two possible outcomes, labeled "success" and "failure". Under the assumption that little or nothing is known a priori about the relative plausibilities of the outcomes, Laplace derived a formula for the probability that the next trial will be a success.

where s is the number of previously observed successes and n is the total number of observed trials. It is still used as an estimator for the probability of an event if we know the event space, but only have a small number of samples.

The rule of succession has been subject to much criticism, partly due to the example which Laplace chose to illustrate it. He calculated that the probability that the sun will rise tomorrow, given that it has never failed to in the past, was

where d is the number of times the sun has risen in the past times. This result has been derided as absurd, and some authors have concluded that all applications of the Rule of Succession are absurd by extension. However, Laplace was fully aware of the absurdity of the result; immediately following the example, he wrote, "But this number is far greater for him who, seeing in the totality of phenomena the principle regulating the days and seasons, realizes that nothing at the present moment can arrest the course of it."

Laplace's demon

Main article: Laplace's demon
Laplace strongly believed in causal determinism, which is expressed in the following quote from the introduction to the Essai:

“ We may regard the present state of the universe as the effect of its past and the cause of its future. An intellect which at a certain moment would know all forces that set nature in motion, and all positions of all items of which nature is composed, if this intellect were also vast enough to submit these data to analysis, it would embrace in a single formula the movements of the greatest bodies of the universe and those of the tiniest atom; for such an intellect nothing would be uncertain and the future just like the past would be present before its eyes. ”

This intellect is often referred to as Laplace's demon (in the same vein as Maxwell's demon). Note that the description of the hypothetical intellect described above by Laplace as a demon does not come from Laplace, but from later biographers: Laplace saw himself as a scientist that hoped that humanity would progress in a better scientific understanding of the world, which, if and when eventually completed, would still need a tremendous calculating power to compute it all in a single instant.

Laplace transforms
Main article: Laplace transform#History
As early as 1744, Euler, followed by Lagrange, had started looking for solutions of differential equations in the form:

In 1785, Laplace took the key forward step in using integrals of this form in order to transform a whole difference equation, rather than simply as a form for the solution, and found that the transformed equation was easier to solve than the original.

Other discoveries and accomplishments

Amongst the other discoveries of Laplace in pure and applicable mathematics are:

Discussion, contemporaneously with Alexandre-Théophile Vandermonde, of the general theory of determinants, (1772);
Proof that every equation of an even degree must have at least one real quadratic factor;
Solution of the linear partial differential equation of the second order;
He was the first to consider the difficult problems involved in equations of mixed differences, and to prove that the solution of an equation in finite differences of the first degree and the second order might be always obtained in the form of a continued fraction; and
In his theory of probabilities:
Evaluation of several common definite integrals; and
General proof of the Lagrange reversion theorem.

Surface tension
Main article: Young-Laplace equation#History
Laplace built upon the qualitative work of Thomas Young to develop the theory of capillary action and the Young-Laplace equation.

Speed of sound
Laplace in 1816 was the first to point out that the speed of sound in air depends on the heat capacity ratio. Newton's original theory gave too low a value, because it does not take account of the adiabatic compression of the air that results in a local rise in temperature and pressure. Laplace's investigations in practical physics were confined to those carried on by him jointly with Lavoisier in the years 1782 to 1784 on the specific heat of various bodies.

Political ambitions
According to W. W. Rouse Ball, as Napoleon's power increased Laplace begged him to give him the post of Minister of the Interior. However this is disputed by Pearson. Napoleon, who desired the support of men of science, did make him Minister of the Interior in November 1799, but a little less than six weeks saw the close of Laplace's political career. Napoleon later (in his Mémoires de Sainte Hélène wrote of his dismissal as follows:

Géomètre de premier rang, Laplace ne tarda pas à se montrer administrateur plus que médiocre; dès son premier travail nous reconnûmes que nous nous étions trompé. Laplace ne saisissait aucune question sous son véritable point de vue: il cherchait des subtilités partout, n'avait que des idées problématiques, et portait enfin l'esprit des `infiniment petits' jusque dans l'administration. (Geometrician of the first rank, Laplace was not long in showing himself a worse than average administrator; since his first actions in office we recognized our mistake. Laplace did not consider any question objectively: he sought subtleties everywhere, only conceived problems, and finally carried the spirit of "hair-splitting" into the administration.)

Although Laplace was removed from office it was desirable to retain his allegiance. He was accordingly raised to the senate, and to the third volume of the Mécanique céleste he prefixed a note that of all the truths therein contained the most precious to the author was the declaration he thus made of his devotion towards the peacemaker of Europe. In copies sold after the Bourbon Restoration this was struck out. (Pearson points out that the censor would not have allowed it anyway.) In 1814 it was evident that the empire was falling; Laplace hastened to tender his services to the Bourbons, and in 1817 during the Restoration he was rewarded with the title of marquis.

According to Rouse Ball, the contempt that his more honest colleagues felt for his conduct in the matter may be read in the pages of Paul Louis Courier. His knowledge was useful on the numerous scientific commissions on which he served, and probably accounts for the manner in which his political insincerity was overlooked; but the pettiness of his character must not make us forget how great were his services to science.

He died in Paris in 1827. His brain was removed by his physician, François Magendie, and kept for many years, eventually being displayed in an roving anatomical museum in Britain. It was reportedly smaller than the average brain.

Asteroid 4628 Laplace is named for him.
He is one of only seventy-two people to have their names on the Eiffel Tower.

Astrological portrait of Pierre-Simon Laplace (excerpt)

Disclaimer: these short excerpts of astrological charts are computer processed. They are, by no means, of a personal nature. This principle is valid for the 47,403 celebrities included in our database. These texts provide the meanings of planets, or combination of planets, in signs and in houses, as well as the interpretations of planetary dominants in line with modern Western astrology rules. Moreover, since Astrotheme is not a polemic website, no negative aspect which may damage the good reputation of a celebrity is posted here, unlike in the comprehensive astrological portrait.


Your Comprehensive Astrological Portrait

Here are some character traits from Pierre-Simon Laplace's birth chart. This description is far from being comprehensive but it can shed light on his/her personality, which is still interesting for professional astrologers or astrology lovers.

In a matter of minutes, you can get at your email address your astrological portrait (approximately 32 pages), a much more comprehensive report than this portrait of Pierre-Simon Laplace.

N.B.: As this celebrity's birth time is unknown, the chart is drawn for 12:00 PM - the legal time for his/her place of birth; since astrological houses are not taken into account, this astrological profile excerpt is less detailed than those for which the birth time is known.

The dominant planets of Pierre-Simon Laplace

When interpreting a natal chart, the best method is to start gradually from general features to specific ones. Thus, there is usually a plan to be followed, from the overall analysis of the chart and its structure, to the description of its different character traits.

In the first part, an overall analysis of the chart enables us to figure out the personality's main features and to emphasize several points that are confirmed or not in the detailed analysis: in any case, those general traits are taken into account. Human personality is an infinitely intricate entity and describing it is a complex task. Claiming to rapidly summarize it is illusory, although it does not mean that it is an impossible challenge. It is essential to read a natal chart several times in order to absorb all its different meanings and to grasp all this complexity. But the exercise is worthwhile.

In brief, a natal chart is composed of ten planets: two luminaries, the Sun and the Moon, three fast-moving or individual planets, Mercury, Venus and Mars, two slow-moving planets, Jupiter and Saturn, and three very slow-moving planets, Uranus, Neptune and Pluto. Additional secondary elements are: the Lunar Nodes, the Dark Moon or Lilith, Chiron and other minor objects. They are all posited on the Zodiac wheel consisting of twelve signs, from Aries to Pisces, and divided into twelve astrological houses.

The first step is to evaluate the importance of each planet. This is what we call identifying the dominant planets. This process obeys rules that depend on the astrologer's sensitivity and experience but it also has precise and steady bases: thus, we can take into account the parameters of a planet's activity (the number of active aspects a planet forms, the importance of each aspect according to its nature and its exactness), angularity parameters; (proximity to the four angles, Ascendant, Midheaven, Descendant and Imum Coeli or Nadir, all of them being evaluated numerically, according to the kind of angle and the planet-angle distance) and quality parameters (rulership, exaltation, exile and fall). Finally, other criteria such as the rulership of the Ascendant and the Midheaven etc. are important.

These different criteria allow a planet to be highlighted and lead to useful conclusions when interpreting the chart.

The overall chart analysis begins with the observation of three sorts of planetary distributions in the chart: Eastern or Western hemisphere, Northern or Southern hemisphere, and quadrants (North-eastern, North-western, South-eastern and South-western). These three distributions give a general tone in terms of introversion and extraversion, willpower, sociability, and behavioural predispositions.

Then, there are three additional distributions: elements (called triplicity since there are three groups of signs for each one) - Fire, Air, Earth and Water - corresponding to a character typology, modality (or quadruplicity with four groups of signs for each one) - Cardinal, Fixed and Mutable - and polarity (Yin and Yang).

There are three types of dominants: dominant planets, dominant signs and dominant houses. The novice thinks astrology means only "to be Aries" or sometimes, for example, "to be Aries Ascendant Virgo". It is actually far more complex. Although the Sun and the Ascendant alone may reveal a large part of the character - approximately a third or a half of your psychological signature, a person is neither "just the Sun" (called the sign) nor just "the first house" (the Ascendant). Thus, a particular planet's influence may be significantly increased; a particular sign or house may contain a group of planets that will bring nuances and sometimes weaken the role of the Ascendant, of the Sun sign etc.

Lastly, there are two other criteria: accentuations (angular, succedent and cadent) which are a classification of astrological houses and types of decanates that are occupied (each sign is divided into three decanates of ten degrees each). They provide some additional informations.

These general character traits must not be taken literally; they are, somehow, preparing for the chart reading. They allow to understand the second part of the analysis, which is more detailed and precise. It focuses on every area of the personality and provides a synthesis of all the above-mentioned parameters according to sound hierarchical rules.

Warning: when the birth time is unknown, which is the case for Pierre-Simon Laplace, a few paragraphs become irrelevant; distributions in hemispheres and quadrants are meaningless, so are dominant houses and houses' accentuations. Therefore, some chapters are removed from this part.

For all paragraphs, the criteria for valuation are calculated without taking into account angles and rulerships of the Ascendant and of the Midheaven. The methodology retains its validity, but it is less precise without a time of birth.

Elements, Modalities and Polarities for Pierre-Simon Laplace

The predominance of Water signs indicates high sensitivity and elevation through feelings, Pierre-Simon Laplace. Your heart and your emotions are your driving forces, and you can't do anything on Earth if you don't feel a strong affective charge (as a matter of fact, the word "feeling" is essential in your psychology). You need to love in order to understand, and to feel in order to take action, which causes a certain vulnerability which you should fight against.

Pierre-Simon Laplace, Fire is dominant in your natal chart and endows you with intuition, energy, courage, self-confidence, and enthusiasm! You are inclined to be passionate, you assert your willpower, you move forward, and come hell or high water, you achieve your dreams and your goals. The relative weakness of this element is the difficulty to step back or a kind of boldness that may prompt you to do foolish things.

Earth qualities are under-represented in your chart, with only 0.00% instead of the average 25%. Deficiency in Earth may indicate that you have no interest in material and concrete values. It is likely that you live too much in your heart or in your mind, or even in your enthusiasm! The fact remains that you may end up in tricky situations, due to your lack of good sense or forethought: material life is unavoidable even if you are rather idealistic, dreamy, or easily content. You must tackle concrete life necessities, for fear of... being forced to cope with them, later, in much more unpleasant ways!

The twelve zodiacal signs are split up into three groups or modes, called quadruplicities, a learned word meaning only that these three groups include four signs. The Cardinal, Fixed and Mutable modes are more or less represented in your natal chart, depending on planets' positions and importance, and on angles in the twelve signs.

The Mutable mode is the most emphasized one in your natal chart, Pierre-Simon Laplace, which indicates a mobile character that is curious and thirsty for new experiences and evolution. You are lively and flexible, and you like to react quickly to solicitations, but don't confuse mobility with agitation, since this is the danger with this configuration - and with you, stagnation is out of the question. Security doesn't matter as long as you are not bored. You optimize, you change things, you change yourself... all this in a speedy way.

The twelve signs are divided into two polarities, called active or passive, or sometimes masculine and feminine, positive and negative, Yang and Yin. This classification corresponds to two quite distinct tonalities, the first one bringing extraversion, action, self-confidence and dynamism, the second one, introversion, reactivity, reflection and caution. None is superior to the other, each group has its own assets and shortcomings. Odd signs - Aries, Gemini, Leo, Libra, Sagittarius and Aquarius - belong to the first group, whereas even signs - Taurus, Cancer, Virgo, Scorpio, Capricorn and Pisces - belong to the second group.

N.B.: this dominant is a minor one. It is not essential that you read its meaning in the beginning. You can get back to them later on, once you have read more important interpretations.

According to the disposition and qualities of your planets and angles, you are rather influenced by Yang energy, the active polarity, Pierre-Simon Laplace: more concerned about actions than reflection, you sometimes rush without standing back and without the deepness that is needed. However, your spontaneity prompts you to take fresh starts, even after repeated failures caused by your rashness.

Each sign contains 30 degrees and can be divided into three equal parts: the decanates. The Tradition indicates that specific meanings can be associated to each of the three decanates. Their sphere of activity is usually limited to the Sun sign, however, it is even more interesting to observe the distribution of all the planets in the chart to get an idea of the respective importance of the three decanates, which can complement the description of the personality.

These meanings must be considered with the greatest caution. Indeed, they are minor characteristics that can only underline other outstanding traits of character.

Traditionally, the first decanate highlights the characteristics of the sign where a planet is located. The two other decanates correspond to sub-dominant planets, depending on the nature of each sign. This system leads to a multiplication of meanings and it is impossible to have a clear understanding: here, we prefer to give only the meaning of one decanate in comparison with the other two, within the birth chart as a whole. Again, the greatest caution is needed with regard to this minor indication as it is not always reliable: it is not essential that you read these texts in the beginning. You can get back to them later on, once you have read more important interpretations

The first decanate, which means the part between 0° and 10° of any zodiacal sign, prevails in your natal chart, Pierre-Simon Laplace: this decanate is traditionally linked to vitality and physical constitution, and may indicate that you efficiently express your concrete energy on the material and sensual planes.

Dominants: Planets, Signs and Houses for Pierre-Simon Laplace

The issue of dominant planets has existed since the mists of time in astrology: how nice it would be if a person could be described with a few words and one or several planets that would represent their character, without having to analyse such elements as rulerships, angularities, houses, etc!

The ten planets - the Sun throughout Pluto - are a bit like ten characters in a role-play, each one has its own personality, its own way of acting, its own strengths and weaknesses. They actually represent a classification into ten distinct personalities, and astrologers have always tried to associate one or several dominant planets to a natal chart as well as dominant signs and houses.

Indeed, it is quite the same situation with signs and houses. If planets symbolize characters, signs represent hues - the mental, emotional and physical structures of an individual. The sign in which a planet is posited is like a character whose features are modified according to the place where he lives. In a chart, there are usually one, two or three highlighted signs that allow to rapidly describe its owner.

Regarding astrological houses, the principle is even simpler: the twelve houses correspond to twelve fields of life, and planets tenanting any given house increase that house's importance and highlight all relevant life departments: it may be marriage, work, friendship etc.

In your natal chart, Pierre-Simon Laplace, the ten main planets are distributed as follows:

The three most important planets in your chart are Venus, Pluto and Uranus.

With Venus among your dominant planets, one of your first reflexes is... to please! Your look, your charm, and your seduction are omnipresent elements in your behaviour.

Your approach to things is connected to your heart, and for you, no real communication can flow if your interlocutors exude no sympathy or warmth. Cold and logical reasoning, clear thoughts and good sense are not important to you: if there is no affective bond with your environment, no connection can be established with the Venusian that you are, and nothing happens.

You have a strong artistic side, and you never neglect subjective but clear concepts such as pleasure, beauty, and also sensuality. However, sometimes to the detriment of efficiency, durability, logic, and... detachment.

With Pluto as a dominant planet in your chart, you are a magnetic and mighty predator, like the Scorpio sign ruled by this planet, who needs to exert pressure on others in order to "test" them. You are always ready to evolve, to risk destruction for reconstruction - including your own - to live more intensely whilst imposing your secret authority on things and on people you encounter.

You may come across as wicked, cruel or too authoritarian, but actually you only follow your instinct, you sound people out, and you like to exert your domination simply because your vital energy is too powerful to remain inside. You are inclined to be passionate, with hidden motivations. You are sometimes misunderstood but one of your great Plutonian assets is to go successfully through each life ordeal with ever growing strength.

Uranus is among your dominant planets: just like Neptune and Pluto, Uranian typology is less clearly defined than the so-called classical seven planets that are visible to the naked eye, from the Sun to Saturn. However, it is possible to associate your Uranian nature with a few clear characteristics: Uranus rhymes with independence, freedom, originality, or even rebelliousness and marginality, when things go wrong...

Uranus is Mercury's higher octave and as such, he borrows some of its traits of character; namely, a tendency to intellectualize situations and emotions with affective detachment, or at least jagged affectivity.

Therefore, you are certainly a passionate man who is on the lookout for any kind of action or revolutionary idea, and you are keen on new things. Uranians are never predictable, and it is especially when they are believed to be stable and well settled that... they change everything - their life, partner, and job! In fact, you are allergic to any kind of routine, although avoiding it must give way to many risks.

In your natal chart, the three most important signs - according to criteria mentioned above - are in decreasing order of strength Pisces, Sagittarius and Gemini. In general, these signs are important because your Ascendant or your Sun is located there. But this is not always the case: there may be a cluster of planets, or a planet may be near an angle other than the Midheaven or Ascendant. It may also be because two or three planets are considered to be very active because they form numerous aspects from these signs.

Thus, you display some of the three signs' characteristics, a bit like a superposition of features on the rest of your chart, and it is all the more so if the sign is emphasized.

Pisces is among your dominant signs and endows your personality with unlimited sources of emotions, dreams, imagination, and sensitivity, to the extent that you literally swim in a cloudy ocean of delightful impressions. These impressions are so intense and overwhelming that you don't really need to take action concretely, to show your dynamism or your willpower, since you already live so intensely with your feelings - you are as keen as a radar, always on the alert! That is why some people may not like your carelessness, and the lack of clarity in your opinions or actions; however they quickly notice your artistic talents, your poetic or artistic side, and your total lack of wickedness. Besides, you feel compassion for people in pain - empathy is one of your great qualities. Thanks to your flexibility, your intuition, and your generosity, you may spend an important part of your life helping others. And if you are creative or if you have well-known artistic talents, everybody will forgive your little flaws: absent-mindedness, lack of energy or of will, too dreamy temperament...

Sagittarius, an adventurous and conquering fire sign, is dominant in your chart: you are enthusiastic, enterprising, optimistic, very sociable, and mobile - you have itchy feet, both physically and mentally. Nobody gets bored with you because you are always planning things and suggesting excursions, at least... when you are around and not already gone on a trip! Obviously, so many movements for one man may scare people off, and some of them may even criticize your brutality or your tendency to loose your temper, but you are so warm and genuine, so expansive, isn't this a good thing? And all the more so, since your sense of humour is overwhelming...

With Gemini as a dominant sign, your qualities include being lively, curious, mobile, clever, and flexible: you often make others dizzy, and you may come across as a dilettante - a bit inquisitive, shallow, and insensitive because you may be too intellectualizing. However, your natural curiosity, a nice quality, and your quick humour, allow you to demonstrate to everyone how much they may gain from your company, and that your apparent flightiness hides an appetite (particularly mental) for life, which itself conceals a terrific charm!

After this paragraph about dominant planets, of Pierre-Simon Laplace, here are the character traits that you must read more carefully than the previous texts since they are very specific: the texts about dominant planets only give background information about the personality and remain quite general: they emphasize or, on the contrary, mitigate different particularities or facets of a personality. A human being is a complex whole and only bodies of texts can attempt to successfully figure out all the finer points.

Your sensitivity

Pierre-Simon Laplace, you tend to hold emotions at bay, as if they were dangerous. You observe with curiosity what is occurring and you strive to objectively, logically and impersonally analyze facts in order to form correct judgments. Contacts and communication are very important to you, Pierre-Simon Laplace, you make use of, even over-use, words, with deep humour because it is an additional way for you to be detached from your feelings. You may come across as superficial because you keep on talking without committing yourself. You need to be constantly on the move, to discover and to communicate in order to avoid boredom. When you are alone, you can spend lots of time with books to nourish your mind that is so avid for knowledge. However, be careful not to miss feelings because you favour intellectual sensations...

Your intellect and your social life

Your thinking process works on a rather instinctive and intuitive mode, Pierre-Simon Laplace. You “feel” more than you understand, as if your reasoning were not active. Your strong receptivity and your natural empathy make you an understanding, pleasant, warm and benevolent person although you may be neglectful, even heedless. You are shy and anxious and you prefer to withdraw and to isolate yourself in a quiet place in order to give free rein to your inspiration, rather than to assert yourself. Despite your lively imagination, it may be hard for you to get out of the flow of your mystical and irrational thoughts, with the result that you become even more worried and impressionable. You must develop your logic, rational mind and your willpower, so as to gain self-confidence and creativity. Try and see...

Your affectivity and your seductiveness

In your chart, the Sun is in Aries and Venus, in Pisces. Paradoxical association: the enthusiasm and the spring freshness of the Aries Sun echo the subtlety and the distance of a Piscean Venus. Your aspirations (solar), prompt you to be carried away by your heart impulses and to exchange with spontaneity … but your desires (Venusian) obey different rules that are elusive, and sometimes, irrational. Between the beginning and the end, the frontier is often tenuous and the balance is fragile. Your affective behaviour may seem disconcerting because you can abruptly shift from enthusiasm to renunciation. This is because your senses do not follow your ideals, because your desires do not match the patterns that appeal to you, as sincere as they may be. Your loved one does not necessarily resemble the conceptualized ideal you dream of. Attraction – or repulsion – is based on ineffable impressions that short-lived and sudden impulses cannot erase nor construct. Although you may show a certain naivety, your senses quickly discriminate between the one-night-stand illusory enthusiasm and the essential harmony without which two persons drift apart, sooner or later. Love is not simple! And if it were, indifference would rapidly triumph over the wildest feelings.

Compassion and self-sacrifice: you are fond of this romantic mode and you are willing to express your feelings, the intensity of which is unlimited, Pierre-Simon Laplace. With excitement and imagination, you dream your amorous relationships as much as you actually live through them. The line between the concrete world and your huge hopes is so tenuous that you don't know anymore where it is, although your particularly rich sensuality prompts you to experience your feelings concretely. You want to share communion and passion with your partner. The lyrical flights of your feelings break from your heart as waves that you do not attempt to control because they give you a real, almost voluptuous and carnal joy. You give a lot – sometimes too much - without reservation, almost without propriety, totally revealing your vulnerability during your amorous exchanges because you are sure of the quality and the might of your feelings: they are so powerful and overwhelming that you are aware that nothing can resist them.

Your will and your inner motivations

Your natural energy is cut-and-dried. It may prompt you to take the driver’s seat wherever you are. Were it not for the strange feeling of sympathy you arouse, you would seem to be arrogant. Charging ahead is not devoid of drawbacks. Your courage and your restlessness may hurt you and cause you to doubt, all of a sudden. As a consequence, your courage, your honesty, your enthusiasm and your straightforwardness may turn into aggressiveness, rebellion and vulnerability that were never suspected. Fortunately, the level of your dynamism is very high and your instinctive and pugnacious side, your particularly profuse energy will not leave you helpless for too long. The fire in your blood will put you back on the saddle towards new stampedes and conquests, as ambitious and glorious as they are perilous.

Because you are born under this sign, you are courageous, honest, enthusiastic, dynamic, swift, extroverted, straightforward, effusive, warm, impulsive, adventurous, bold, martial, competitive, but you may also be gullible, domineering, self-centered, impatient, foolish, thoughtless, childish, irascible, reckless, primary and a blunderer.

In love, Sir, more often than not, your passions are strong and varied. Far from being roadblocks, obstacles have a stimulating effect. You like quick victories and your love life is a series of conquests and of break-ups, as boredom often puts an end to the initial love that made you move mountains.

Your sexuality is powerful and prevails over feelings. You may marry early or on impulse, but it does not prevent you from having a rich and varied love life. Usually, you have few children.

Your ability to take action

Pierre-Simon Laplace, you are a real Goliath and you often excel in sport; your thirst for conquests prompts you to constantly launch new challenges. The enthusiasm you put in your undertakings is perfectly well supported by your moral concepts and an idealism compatible with the values of the society you live in. You are pragmatic, enterprising and sometimes, naive. You do not pay attention to details and you launch various great adventurous projects that are all doomed to success. In a few rare cases, you can funnel your huge energy into more philosophical, even spiritual or religious enterprises, where your entire fieriness works wonders. On the sexual plane, your ardour and your spontaneity are your main assets. The danger is that you may spread yourself too thin in the sense that you may forget about faithfulness, particularly during the extensive faraway travels you are so fond of.

Astrological studies describe many of the character traits and they sometimes go deeper into the understanding of a personality. Please, always keep in mind that human beings are continuously evolving and that many parts of our psychological structures are likely to be expressed later, after having undergone significant life's experiences. It is advised to read a portrait with hindsight in order to appreciate its astrological content. Under this condition, you will be able to take full advantage of this type of study.

The analysis of an astrological portrait consists in understanding four types of elements which interact with one another: ten planets, twelve zodiacal signs, twelve houses, and what are called aspects between planets (the 11 aspects most commonly used are: conjunction, opposition, square, trine, sextile, quincunx, semi-sextile, sesqui-quadrate, quintile and bi-quintile. The first 5 aspects enumerated are called major aspects).

Planets represent typologies of our human psychology: sensitivity, affectivity, ability to undertake, will-power, mental process, aptitude, and taste for communication etc., all independent character facets are divided here for practical reasons. The twelve signs forming the space where planets move will "colour", so to speak, these typologies with each planet being located in its particular sign. They will then enrich the quality of these typologies, as expressed by the planets. The Zodiac is also divided into twelve astrological houses. This makes sense only if the birth time is known because within a few minutes, the twelve houses (including the 1st one, the Ascendant) change significantly. They correspond to twelve specific spheres of life: external behaviour, material, social and family life, relationship, home, love life, daily work, partnership, etc. Each planet located in any given house will then act according to the meaning of its house, and a second colouration again enriches those active forces that the planets symbolize. Finally, relations will settle among planets, creating a third structure, which completes the planets' basic meanings. A set of ancient rules, which has stood the test of experience over hundreds of years (although astrology is in evolution, only reliable elements are integrated into classical studies), are applied to organize the whole chart into a hierarchy and to allow your personality to be interpreted by texts. The planets usually analysed are the Sun, the Moon, Mercury, Venus, Jupiter, Saturn, Uranus, Neptune and Pluto, which means two luminaries (the Sun and the Moon) and 8 planets, a total of 10 planets. Additional secondary elements may be taken into account, such as asteroids Chiron, Vesta, Pallas, Ceres (especially Chiron, more well-known), the Lunar nodes, the Dark Moon or Lilith, and even other bodies: astrology is a discipline on the move. Astrological studies, including astrological portrait, compatibility of couples, predictive work, and horoscopes evolve and become more accurate or deeper, as time goes by.

Precision: concerning the horoscopes with a known time of birth, according to the Tradition, we consider that a planet near the beginning (called cuspide) of the next house (less than 2 degrees for the Ascendant and the Midheaven, and less than 1 degree for all other houses) belongs to this house: our texts and dominants take this rule into account. You can also choose not to take this shift into account in the form, and also tick the option Koch or Equal houses system instead of Placidus, the default houses system.

Warning: In order to avoid any confusion and any possible controversy, we want to draw your attention upon the fact that this sample of celebrities is very complete and therefore, it also includes undesirable people, since every category is represented: beside artists, musicians, politicians, lawyers, professional soldiers, poets, writers, singers, explorers, scientists, academics, religious figures, saints, philosophers, sages, astrologers, mediums, sportsmen, chess champions, famous victims, historical characters, members of royal families, models, painters, sculptors, and comics authors or other actual celebrities, there are also famous murderers, tyrants and dictators, serial-killers, or other characters whose image is very negative, often rightly so.

Regarding the latter, it must be remembered that even a monster or at least a person who perpetrated odious crimes, has some human qualities, often noticed by his/her close entourage: these excerpts come from computer programmes devoid of polemical intentions and may seem too soft or lenient. The positive side of each personality is deliberately stressed. Negative sides have been erased here - it is not the same in our comprehensive reports on sale - because it could hurt the families of such people. We are hoping that it will not rebound on the victims' side.

Numerology: Birth Path of Pierre-Simon Laplace

Testimonies to numerology are found in the most ancient civilizations and show that numerology pre-dates astrology. This discipline considers the name, the surname, and the date of birth, and ascribes a meaning to alphabetic letters according to the numbers which symbolise them.

The path of life, based on the date of birth, provides indications on the kind of destiny which one is meant to experience. It is one of the elements that must reckoned with, along with the expression number, the active number, the intimacy number, the achievement number, the hereditary number, the dominant numbers or the lacking numbers, or also the area of expression, etc.

Your Birth Path:

Your Life Path is influenced by the Master Number 11, Pierre-Simon, which indicates a strong, demanding, and uncompromising destiny. It is all about revelation and early calling. You feel that you are entrusted with a mission, with the certainty that no setback could endanger it, and your own certitudes prevail over any other motivation. You have a lot of strength, and sometime, intransigence. Short-lived fashions and life vagaries cannot weaken your beliefs. You pursue a set direction, in quest of an extraordinary destiny, with the help of your intelligence, your inspiration and the natural influence you have over people. Even though your entourage may not always understand your secret determination and perceive you mainly as an impatient person, your fortitude overcomes many a doubt and obstacle. You can sacrifice everything for the sake of your deep aspirations.

N. B.: when the birth time is unknown, (12:00 PM (unknown)), these portrait excerpts do not take into account the parameters derived from the time, which means, the domification (Ascendant, astrological houses, etc.). Nonetheless, these analyses remain accurate in any case. Regarding the sources of the birth data in our possession, kindly note that the pages we publish constitute a starting point for more detailed research, even though they seem useful to us. When the sources are contradictory, which occurs rarely, after having analysed them, we choose the most reliable one. Sometimes, we publish a birth date just because it is made available, but we do not claim that is it the best one, by no means.
