Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...

Imaging spectropolarimetry techniques represent a blend of spectroscopy, imaging, and polarimetry to provide comprehensive information on the optical properties of targets. These methods enable the ...

A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...
