XKCD comic on Fourier series sparks recognition among mathematicians

XKCD publishes comic on Fourier series and Gibbs phenomenon

XKCD releases a comic addressing Fourier series approximations and the Gibbs phenomenon, the mathematical phenomenon where overshoots persist at discontinuities even as more terms are added to the series expansion.

“If you've done Fourier series approximations of functions, you had three reactions to today's XKCD comic: First, of course, was a smile of recognition. Then came a 'wait a minute' as you realized that the Gibbs phenomenon doesn't get smaller as you add more terms to the Fourier expansion; it just concentrates itself at the corners.”
