	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.

		The Fourier transform, named after Jean Baptiste Joseph Fourier, is an integral transform that re-expresses a function in terms of sinusoidal basis functions, i.
		In mathematics, a Fourier series, named in honor of Joseph Fourier (1768-1830), is a representation of a periodic function (often taken to have period 2π — in a sense, the simplest case) as a sum of periodic functions of the form which are harmonics of ei x.
		Fourier reported on an experiment by M. de Saussure with a fl box exposed to the Sun, and in which if thin glass is put on top of the box the temperature inside of the box increases [1] (http://www.wmconnolley.org.uk/sci/fourier_1827/fourier_1827.html#text).

		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.

		Joseph Fourier was a young scientist in the employ of Napoleon.
		The basic thesis of his theory was that if one had a complete set of functions, any arbitrary function could be accurately described by a linear combination of the various members of this complete set of functions.
		Fourier analysis is extremely important in modern mathematics and the ideas are the basis upon which will describe the wavefunction of complex systems such as molecule and solids.
