Precursor of projective geometry
Monge considered the problem of representing three-dimensional objects on a plane for purposes of engineering and such, but he quickly realised that his ideas can yield great insights in pure geometry as well. A particularly illustrative and important case where Monge anticipates the projective geometry of Poncelet is the theory of poles and polars. Polar reciprocation with respect to a circle associates a line with every point and a point with every line as follows. Consider a line that cuts through the circle. It meets the circle in two points. Draw the tangents to the circle through these points. The two tangents meet in a point. This point is the pole of the line. Conversely, the line is the polar of the point. Thus we can deal with lines that cut through the circle and, equivalently, points outside the circle. But what about a line outside the circle (or, equivalently, a point inside the circle)? Let L be such a line. For every point on L there is a polar line through the circle, as above. We claim that all these polar lines have one point in common, so that this point is the natural pole of L. Monge proves this by cleverly bringing in the third dimension. Imagine a sphere that has the circle as its equator. Every point on L is the vertex of a tangent cone to this sphere. The two tangents to the equator are part of this cone and the polar line is the perpendicular projection of the circle of intersection of the sphere and the cone. Now consider a plane through L tangent to the sphere. It touches the sphere at one point P. Every cone contains this point (because the line from any point on L to P is a tangent to the sphere and so is part of the tangent cone). Thus, for every cone, the perpendicular projection of the intersection with the sphere goes through the point perpendicularly below P, and this is the pole of L, and L is the polar of this point.

Mises à jour gratuites en ligne. Extrait : Edmond (ou Edmund) Halley (29 octobre 1656, Haggerston, borough de Hackney à Londres - 14 janvier 1742, Greenwich) est un astronome et ingénieur britannique. Ingénieur et scientifique pluridisciplinaire, il est surtout connu pour avoir le premier déterminé la périodicité de la comète de 1682, qu'il fixa par calcul à 76 ans environ. Lors du retour de cette comète en 1758, elle fut baptisée de son nom. C'est l'une des rares comètes qui portent un autre nom que celui de leur découvreur. La date de sa naissance est incertaine : Halley croyait pour sa part qu'il s'agissait du 29 octobre 1656. Il naquit dans le village de Hackney, petit village des environs de Londres, aujourd'hui absorbé par la capitale. De sa mère nous ne connaissons que le nom, Anne Halley, née Robinson. Son père se prénommait également Edmond, et c'était un riche savonnier et marchand de sels qui avait bâti sa fortune sur les récentes horreurs de la peste bubonique, qui avait donné aux londoniens le goût de l'hygiène corporelle. Cet homme n'eut jamais peur de co...http://booksllc.net/?l=fr ... Read more

Non illustré. Mises à jour gratuites en ligne. Extrait : Le Panthéon est un monument de style néo-classique situé Place du Panthéon sur la montagne Sainte-Geneviève, dans le 5 arrondissement de Paris, au cœur du quartier latin. Il est entouré notamment par l'église Saint-Étienne-du-Mont, la bibliothèque Sainte-Geneviève, l'université de Paris I (Panthéon-Sorbonne) et l'université de Paris IV, l'université de Paris II (Panthéon-Assas), le lycée Louis-le-Grand, la mairie du 5 arrondissement et le lycée Henri-IV. La rue Soufflot lui dessine une perspective à partir du jardin du Luxembourg. Construit à l'origine au siècle comme une église pour abriter la châsse de sainte Geneviève, ce monument a maintenant vocation à honorer des personnages et rappeler des événements ayant marqué l'Histoire de France. Ses différentes destinations successives, sa décoration, les inscriptions et les symboles qui y figurent, permettent de parcourir la construction - lente et contrastée - de la nation française. Ce monument est ouvert au public et géré par le Centre des monuments nationaux. Dôme du Panthéon Intérieur du PanthéonEn 1744, se trouvant à Metz et souffrant d'une grave maladie, Louis XV fait le vœu, s'il survit, de créer une église dédiée à sainte Geneviève. Rétabli et de retour à Paris, il charge le marquis de Marigny, directeur général des bâtiments, d'édifier le monument en lieu et place de l'ancienne abbaye Sainte-Geneviève, alors en ruines. En 1755, le marquis de Marigny confie la responsabilité des plans à l'architecte Jacques-Germain Soufflot, qui avait envoyé de Rome ...http://booksllc.net/?l=fr ... Read more

Non illustré. Mises à jour gratuites en ligne. Extrait : Georges Jacques Danton, né le 26 octobre 1759 à Arcis-sur-Aube et mort guillotiné le 5 avril 1794 (16 germinal an II) à Paris, est un avocat et un homme politique français. Danton est une des figures emblématiques de la Révolution française tout comme Mirabeau avec qui il partage un prodigieux talent oratoire et un tempérament impétueux, avide de jouissances (les ennemis de la Révolution l'appellent le Mirabeau du ruisseau), ou comme Robespierre, à qui tout l'oppose, le style, le tempérament et le type de talent. Il incarne la « Patrie en danger » dans les heures tragiques de l'invasion d'août 1792 quand il s'efforce de fédérer contre l'ennemi toutes les énergies de la nation : pour vaincre, dit-il, « il nous faut de l'audace, encore de l'audace, toujours de l'audace et la France sera sauvée ! ». Comme Robespierre, il s'est vite constitué autour de sa personne une légende. Et s'est déchaînée entre historiens robespierristes et dantonistes une polémique idéologique et politique qui a culminé sous la IIIe République. Pour les premiers, Danton est un politicien sans scrupules, vénal, capable de trahir la Révolution, pour les seconds, il est un ardent démocrate, un patriote indéfectible, un h...http://booksllc.net/?l=fr ...
