In 1789 the first essay by Fourier on the numerical solution of algebraic equations. In 1794 the central university of teachers and teachers was established in Paris. Fourier he was one of his first students, soon after he was promoted to the faculty as a professor. He was later called in by the newly founded Polytechnic School, where he served as a professor of mathematical analysis.
Fourier He proved to be a discreet diplomat, and on his return to France Napoleon appointed him prefect of the department of Isère, with Grenoble as its capital, where he served from 1801 to 1814. There he wrote the work on the mathematical theory of heat conduction, which it was worth lasting fame.
His first project was presented to the Academy in 1807; a second, greatly expanded version, which received the Academy Award in 1812, was titled Théorie des mouvements de la chaleur dans les corps solides. The first part was printed in book form in 1822 under the title Théorie analytique de la chaleur. It was a masterpiece, not only because it covered the hitherto unexplored field of heat propagation, but also because it contained mathematical techniques that would later be developed in a special branch of mathematics: the Fourier analysis and Fourier integrals.
During the course of your career, Fourier wrote several articles on statistics, but his predilection was in the theory of algebraic equations on which he had just finished a draft for a book, Analyze the determined equations, and a long memoir, when he died in Paris on May 16, 1830.
