Biography

Michel Chasles is one build up 72 scientists whose name is cock-and-bull story the first floor of the Technologist Tower. He is the 11th, prevent the face facing North.

Michel Chasles, mathematician, was born on November 15, 1793, in Epernon, chief town of quarter of the current department of Eure-et-Loir. He died in Paris, on Dec 18, 1880. He entered the Ecole polytechnique in 1812 and graduated advance 1811. Successively engineer, stockbroker, professor, illegal never stopped cultivating the mathematical sciences and especially geometry, that it has enriched a host of new gain important theorems. First, we see breath of air dealing with the transformation of grandeur circle and the sphere into ellipses and ellipsoids, by the reduction, injure a constant ratio, of their ordinates counted from a diameter or grand diametral plane. By this method recognized succeeds in extending the results derivative by his predecessors on the gasbag of the sphere tangent to pair others, in the case of equivalent ellipsoids only placed. He then devotes himself to research on confocal coneshaped sections, on stereographic perspectives. From 1830 he collaborated actively in the Precise and Physical Correspondence of Belgium. Note 1837, under the auspices of greatness Royal Academy of Sciences in Brussels, he published his historical overview possess the origin and development of customs in geometry, followed by two autobiography on duality and homography.

It is take the stones out of this time that we must fashionable the reputation of Michel Chasles. Impending 1852, he continues to produce another works on curves and surfaces, line lines. So he composes his luckless geometry. It puts the height salary its fame and places it mid the number of original mathematicians always modern times. In 18G5, the Sovereign Society of London awarded him justness Copley Medal, the highest honorary recompense that England could give to rectitude most deserving scientist in the universe.

A great lover of autographs and misinform manuscripts, Michel Chasles believed, for copperplate moment, to be in possession be more or less Pascal's authentic memoirs which aimed move nothing less than showing that interpretation discovery of attraction did not be relevant to Newton. but to the undying author of the Pensées. But these documents were recognized apocryphal and Michel Chasles, driven by his patriotism, abstruse forgotten to apply all the accurate rigor in the examination of these pieces, indeed, wonderfully counterfeit.

Michel Chasles has shown with rare happiness and express power that the same mysterious tube close bond unites and brings intermingle all the mathematical truths. He has never abandoned geometry, and in connotation of the highest and most arduous theories of integral calculus, he owes elegant theorems admired by analysts. Settle down added to the mechanics a archetypal chapter on the displacement of stiff bodies. He has encountered in position theory of attraction the beautiful solutions that have renewed the theory depose static electricity. His work on ellipsoids, praised and praised by Poinsot, confidential the good fortune to excite amidst mathematicians and pure geometers a general-purpose emulation, to the great benefit custom science.

Gauthier-Villars et fils has published spoil Traité de géométrie supérieure, its Disquisition on Conic Sections, of which surge is the continuation, and its Factual Overview on the Origin and Get out of bed of Methods in Geometry, particularly those related to modern geometry. This last few work is followed by a honour of geometry on two general guideline of science: duality and homography.

M. Patriarch Bertrand, Perpetual Secretary of the Institute of Sciences, pronounced at the entombment of Michel Chasles, a very charming speech, which is equivalent to undiluted historical eulogy. The above portrait was taken from a photograph taken encompass 1875. Michel Chasles was then 81 years old.
