Development of Fourier Analysis. In 1748 Leonhard Euler used linear combinations of “normal modes” to describe the motion of a vibrating string. If the configuration at some point in time is a linear combination of normal modes, so is the configuration at any subsequent time. - . Solving the . Diffusion Equation. Joseph Fourier.
