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 ...

Reviews ordinary differential equations, including solutions by Fourier series. Physical derivation of the classical linear partial differential equations (heat, wave, and Laplace equations). Solution ...

I’m going to explore some delightful results from pure math, and a head-scratching way that the math appears in basic quantum physics. This may get a little math-y, but please bear with me. I’ll try ...
