  Jean Baptiste Joseph Fourier - LoveToKnow 1911
JEAN BAPTISTE JOSEPH FOURIER (1768-1830), French mathematician, was born at Auxerre on the 21st of March 1768.
Fourier was one of the savants who accompanied Bonaparte to Egypt in 1798; and during this expedition he was called to discharge important political duties in addition to his scientific ones.
In 1826 Fourier became a member of the French Academy, and in 1827 succeeded Laplace as president of the council of the Ecole Polytechnique.

Fourier was born at Auxerre in the Yonne département of France, the son of a tailor.
Joseph Louis Lagrange had shown how the roots of an algebraic equation might be separated by means of another equation whose roots were the squares of the differences of the roots of the original equation.
Fourier is also credited with the discovery in his essay in 1824 that gases in the atmosphere might increase the surface temperature of the Earth [1].

 Biography of Jean-Baptiste-Joseph Fourier
Baron Jean-Baptiste-Joseph Fourier (March 21 1768-May 16, 1830), born in poor circumstances in Auxerre, introduced the idea that an arbitrary function, even one defined by different analytic expressions in adjacent segments of its range (such as a staircase waveform), could nevertheless be represented by a single analytic expression.
Fourier was appointed as Prefect of Isèe by Napoleon in 1802 after a brief return to his former position as Professor of Analysis at the Ecole Polytechnique in Paris.
Fourier’s days in provincial government then ended and he moved to Paris to enter a life of science and scientific administration, being elected to the Académie des Sciences in 1817, to the position of permanent secretary in 1823, and to the Académie Française in 1826.

 "Fourier," Feature Article, August 2005
Fourier conceived the view that scientifically rigorous equations must be dimensionally identical—that is, each term in an equation must have the same dimension.
Fourier was born in Auxerre, France, in 1768.
He originally expressed his famous law as: "The force of the current in a galvanic circuit is directly as the sum of all the tensions, and inversely as the entire reduced length of the circuit." Reduced length is the equivalent length of a copper wire of a standard diameter.

Joseph Fourier was born in 1768 in Auxerre in the département of Yonne; a town steeped in history.
Fourier was warned and therefore prepared a token defence of the town at one gate and left by the other, heading towards Lyons (ostensibly to warn the Bourbons of the danger).
Fourier treated the initial distribution of temperatures around the ring as a superposition of many simple sinusoids that varied from peak to trough to peak an integer number of times along the circumference of the ring.

Jean Baptiste Joseph Fourier (March 21, 1768 - May 16, 1830) was a French mathematician and physicist who is best known for initiating the investigation of Fourier series.
He was born at Auxerre in the Yonne département of France, the son of a tailor, and was educated by the Benedictines.
Fourier left an unfinished work on determinate equations which was edited by Claude Navier, and published in 1831; this contains much original matter, in particular there is a demonstration of Fourier's theorem on the position of the roots of an algebraic equation.

 Fourier and the theory of heat   (Site not responding. Last check: 2007-10-15)
By 1800, alternatives to the caloric hypothesis appeared and, in 1811, Joseph Fourier (1768-1830) published a mathematical theory of heat conduction that was entirely independent of the caloric hypothesis.
Fourier's first step was to avoid speculation about "caloric." In this way, Fourier set the study of the theory of heat in the tradition of rational mechanics, basing it on differential equations that characterized the transmission of heat, equations that were independent of all physical hypotheses.
The heat transmitted between two molecules was proportional to the difference in their temperature and a function of the distance between them, which of course varied with the nature of the intervening substance.

 "Fourier--the Father of Modern Engineering," ME Online Web Exclusive, Aug. 9, 2005
Fourier sent in papers in 1808 and 1809 to meet criticisms, and eventually a prize problem on heat diffusion was proposed by the Institut de France for January 1812, to which he submitted a considerably revised and extended version of the 1807 paper.
Fourier's contemporaries accepted his revolutionary view of homogeneity, not because he had demonstrated its scientific rigor, but solely because he was able to solve many practical and theoretical problems that had never been solved.
Joseph Fourier's many contributions to modern engineering science are so critically important and so pervasive that he is rightly regarded as the father of modern engineering.
