For their “Inspire Her Mind” campaign, Verizon recently released this ad demonstrating some of the subtle ways girls are discouraged from learning more about science, math, and hands-on subjects.

In mathematics, a Fourier series  is a way to represent a wave-like function as a combination of simple sine waves. More formally, it decomposes any periodic function or periodic signal into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex exponentials).
