When the allied armies arrived near Paris on 30 March 1814, Dandelin was in the opposing French army and was wounded on that day. Napoleon abdicated on 6 April, but in the following year he returned for the 100 days. During Napoleon's time back in control of France, Dandelin worked at the Ministry of the Interior under the command of Carnot . After Napoleon was defeated at Waterloo, Dandelin returned to Belgium. He became a citizen of the Netherlands in 1817. Dandelin's early mathematical influence was Quetelet , who was two years younger than him, and his early interests were in geometry. Dandelin has an important theorem on the intersection of a cone and its inscribed sphere with a plane, discovered in 1822, named after him. This theorem shows that if a cone is intersected by a plane in a conic , then the foci of the conic are the points where this plane is touched by the spheres inscribed in the cone.

Dandelin studied at Ghent, then in 1813 he entered the Ecole Polytechnique in Paris. However his career was to be very much influenced by the political events of these turbulent times. In 1813 Dandelin had volunteered to fight the British. In March 1814 the Treaty of Chaumont united Austria, Russia, Prussia and Britain in the aim of defeating Napoleon.

Branch of Science Engineers Branch of Science Mathematicians ... Barile Dandelin, Germinal-Pierre (1794-1847) This entry contributed by Margherita Barile Belgian mathematician and engineer who served in the French and Belgian armies. In the Belgian army, he was in charge of building fortifications. He was only 20 years old when he was awarded the by Lazare Carnot , who at that time was Napoleon's Minister of the Interior. In 1816, Dandelin participated in the construction of two telescopes in Namur. He entered the Royal Academy of Brussels in 1822, thanks to a brilliant geometrical work on the parabolic focal curve, where he presented a new elegant proof of a theorem found by his friend Quetelet, which characterized the foci of conic sections with the points of tangency of what are nowadays known as the Dandelin spheres In a curious paper that he published in 1826, Dandelin transferred the same result to the plane sections of a hyperboloid of revolution, where he also re-demonstrated the theorems of Pascal and Brianchon In 1825, the University of Liège assigned him a professorship for a discipline called "exploitation of mines"; the research in this area took him to Germany and England. Later he taught physics at the University of Namur. His fields of interest ranged from projective geometry and algebra to astronomy and mechanics.

BROWSE ALPHABETICALLY LEVEL: Elementary Advanced Both INCLUDE TOPICS: Basic Math Algebra Analysis Biography Calculus Comp Sci Discrete Economics Foundations Geometry Graph Thry History Number Thry Physics Statistics Topology Trigonometry lassically, conic sections (the ellipse parabola , and hyperbola ) are defined by the intersection of a plane with a cone We take the case of an ellipse; the other cases are quite similar. As a conic section, an ellipse is the intersection of a cone and a plane whose angle to the vertical is larger than that of the generator of the cone. That is, it is the curve that results when a plane slices right through one of the nappes of the cone. In plane geometry, however, an ellipse is the locus of points in the plane, the sum of whose distances from two fixed points, called the foci, remains constant. At first glance it is not obvious that these are definitions of the same mathematical object. To show that they are, Dandelin peformed an ingenious construction. call V Now draw the two tangents to the circle that intersect at V . Then the points of tangency are equidistant from V The standard proof of this fact is straightforward, but we'll content ourselves with noticing that it follows more or less immediately from the symmetry of the situation. Indeed, if we rotate the above figure about its axis of symmetry, we get an immediate extension to the case of a sphere inscribed in a cone:

Three basic concepts in Dandelin's hyperboloid model List of illustrations: picture 1 picture 2 picture 3 picture 25 ... More info How did I find out about Monsieur Dandelin and how I reacted to his work I was first introduced to Monsieur Germinal Pierre Dandelin in Math 309, 1997 Spring by Prof. Bill Casselman . We were studying astronomical math and Dandelin's 3D proof of conic sections properties was a perfect sculpture to initiate our interest. The 3D proof involves a cone with one or two spheres inscribed inside and a cutting plane. Depending on the position of the spheres and the cutting plane with respect to the conic section, one can easily comprehend (when one sees the picture) why the sum/difference of the distance between any given point on the conic curve and the two focal points are constant. (If you are interested in reading more about this, please refer to Xah's conic section page Intrigued by Dandelin's unique geometric approach, I got hold of a copy of his papers

Table of Contents Conic Sections Intersections of parallel planes and a double cone, forming ellipses parabolas , and hyperbolas respectively. Code for above graphics Mathematica Notebook for This Page History Description ... Related Web Sites History Appollonius was the first to base the theory of all three conics on sections of one circular cone, right or oblique. He is also the one to give the name ellipse, parabola, and hyperbola. A brief explanation of the naming can be found in Howard Eves, An Introduction to the History of Math. 6th ed. page 172. (also see J.H.Conway's newsgroup message, link at the bottom) In Renaissance, Kepler's law of planetary motion, Descarte and Fermat's coordinate geometry, and the beginning of projective geometry started by Desargues, La Hire, Pascal pushed conics to a high level. Many later mathematicians have also made contribution to conics, espcially in the development of projective geometry where conics are fundamental objects as circles in Greek geometry. Among the contributors, we may find Newton, Dandelin, Gergonne, Poncelet, Brianchon, Dupin, Chasles, and Steiner. Conic sections is a rich classic topic that has spurred many developments in the history of mathematics. Description Hyperbola ellipse , and parabola are together known as conic sections, or just conics. So called because they are the intersection of a right circular cone and a plane.
