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 ...

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, ...

Marcus du Sautoy argues that mathematics is the driving force behind modern science: Joseph Fourier’s insightful maths. This ten part history of mathematics from Newton to the present day, reveals the ...
