	Jean-Baptiste Joseph Fourier - Wikipedia
		Jean-Baptiste Joseph Fourier (Auxerre, 21 maart 1768– Parijs, 16 mei 1830) was een bekend Frans wis- en natuurkundige.
		Fourier claimde dat alle functies van een variabele, of ze nu continu of discontinu zijn, kunnen worden uitgeschreven als een reeks van sinussen van veelvouden van deze variabelen.
		Fourier werd geboren in Auxerre als zoon van een kleermaker en ontving onderwijs in de krijgsschool van Auxerre.

	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.
		By 1807, despite official duties, Fourier had written down his theory of heat conduction, which depended on the essential idea of analyzing the temperature distribution into spatially sinusoidal components: but doubts expressed by Laplace and Lagrange hindered publication.
		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.

	Joseph Fourier
		Joseph Fourier was a young scientist in the employ of Napoleon.
		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.
		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 served from 1798 to 1802 as secretary of the Institut d'Égypte, established by Napoleon to explore systematically the archeological riches of that ancient land.
		Fourier proved himself a tactful diplomat, and upon his return to France Napoleon appointed him perfect of the department of lsère, with Grenoble as its capital, where he served from 1801 to 1814.

	Joseph Fourier
		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.

		Fourier sem a necessária autoridade para deixar seu posto e salvar-se do perigo, lá ficou até 1801, quando os franceses, depois de Trafalgar, finalmente reconheceram que os britânicos e não eles deviam regenerar os Egípcios.
		Em dezembro de 1789 Fourier foi a Paris para apresentar, na Academia, suas pesquisas para a solução de equações numéricas, assunto que o interessou pelo resto da vida.

	SURFING THE WAVELETS
		The advent of the Fourier Series in the early 1800's by Joseph Fourier (1768-1830) provided the foundations for modern signal analysis, a well as the basis for a significant proportion of the mathematical research undertaken in the 19th and 20th centuries.
		In his principal composition, "The Analytic Theory of Heat", Joseph Fourier established the partial differential equations governing heat diffusion and solved it by using an infinite series of trigonometric functions, the Fourier series.
		This is due to the Fourier transform being based on the assumption that the signal to be transformed is periodic in nature and of infinite length.

		In it, Fourier developed the theory of the series known by his name and applied it to the solution of boundary-value problems in partial differential equations.
		Fourier's masterpiece was his mathematical theory of heat conduction stated in Theorie Analytique de la Chaleur (1822).
		This work brought to a close a long controversy, and henceforth it was generally agreed that almost any function of a real variable can be represented by a series involving the sines and cosines of integral multiples of the variable.

		Het is kenmerkend voor de dubbelzinnigheid die Fourier's leven kenmerkte en de complexiteit van deze periode dat hij een confrontatie met Napoleon vermijdde toen die opweg was naar zijn exil te Elba en Grenoble zou aandoen.
		Na Napoleon's en zijn terugkeer naar Paris kreeg Fourier de post van prefect van het departement van de l'Isère (Grenoble) aangeboden welke hij tegen zijn zin aanvaarde.Het is tijdens deze periode te Grenoble dat zijn belangrijkste wetenschappelijk werk tot stand zou komen.
		En in de tweede plaats was er het ongenoegen van Biot omdat Fourier had nagelaten bij zijn afleiding van de transportvergelijkingen hem te citeren.

	The Fourier Theorem
		A second Excel program FOURIER can be used to visualize the resulting waveform and spectrum for up to twelve sine waves consisting of a fundamental and any combination of harmonics up through the eleventh.
		Fourier Analysis--the mathematical decomposition of a waveform into its component frequencies--is beyond the scope of this course.
		For example, the “BATMAN” wave shown above (also shown on page 85 of the coursepack) was displayed using FOURIER from a combination of a fundamental (1 volt, 0 degrees, 1000 Hz), and a second (0.5 volt at 90 degrees), fourth (0.3 volt at 90 degrees), and sixth harmonic (0.1 volt at 90 degrees).
