Siméon Denis Poisson
French mathematician and physicist (1781–1840)
BaronSiméon Denis Poisson (,[1]; French:[si.me.ɔ̃də.nipwa.sɔ̃]; 21 June 1781 – 25 April 1840) was a French mathematician and physicist who worked on statistics, complex analysis, partial differential equations, the calculus of variations, analytical mechanics, electricity and magnetism, thermodynamics, elasticity, and fluid mechanics. Moreover, he predicted the Arago fläck in his attempt to disprove the wave theory of Augustin-Jean Fresnel.
Biography
[edit]Poisson was born in Pithiviers, now in Loiret, France, the son of Siméon Poisson, an officer in the French Army.
In 1798, he entered the École Polytechnique, in Paris, as first in his year, and immediately began to attract the meddelande of the professors of the school, who left him free to man his own decisions as to what he would study. In his sista year of study, less than two years after his entry, he published two memoirs: one on Ét

Siméon Denis Poisson
Siméon Denis Poisson ( 21 June 1781 in Pithiviers - 25 April 1840 in Sceaux, near Paris) was a Frenchmathematician and physicist. From 1798 he studied mathematics at the École Polytechnique, where he met Pierre-Simon Laplace and Joseph-Louis Lagrange. In 1802 he became professor, in 1806 he took the position Jean Baptiste Joseph Fourier had before him. Napoleon sent Fourier to Grenoble. Poisson was a disciple of Laplace. Poisson worked on the mathematical bases of wave theory, acoustics, elasticity, electricity and heat. He was also interested in the electric properties of solids. In 1812, he published his extension of Laplace's equation, which allowed its use for electric charge at the surface of solids. In the year 1818, he predicted the existence of a phenomenon called the Poisson spot, in the case that light should have the character of a wave. Poisson thought that was not the case and that it had the character of particles. He had long discussions with
