6    Fourier Transform

The French scientist Joseph B. Fourier (1768–1830) developed the first important development in the theory of heat conduction presented to The Academy of Sciences in Paris in 1807. To induce Fourier to extend and improve his theory, the Academy of Sciences in Paris assigned the problem of heat propagation as its prize competition in 1812. The judges were Laplace, Lagrange, and Legendre. Fourier became a member of the Academy of Sciences in 1817. He continued to develop his ideas and eventually authored the applied mathematics classic Théorie Analytique de la Chaleur (or Analytical Theory of Heat) in 1822. Fourier got much due credit, for his techniques revolutionized methods for the solution of partial differential ...
