Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of ...

In this paper we offer a method for constructing functions with many gaps in their supports and in the supports of their Fourier transform. As a result we answer a question of Benedicks [Ben1] and we ...

By using an optical frequency comb as a light source for Fourier transform spectroscopy, scientists show that well-resolved absorption and dispersion spectra can be recorded simultaneously ...

To help get your mind around the concept, [Jez Swanson] has this interactive Fourier transform visualizer that really drives home the important points.
