Super Cool - Mechanical Computer Doing Fourier Transforms

The Fourier transform has many applications in physics and engineering. Fourier transformation from the time domain to the frequency domain transforms differential equations into algebraic equations and convolution into multiplication. This often results in simplification of needed mathematical manipulations. The Fourier transform is reversible, being able to transform from either domain to the other. The term itself refers to both the transform operation and to the function it produces.
