Below are some nerdy illustrations from my Fourier Series/Partial Differential Equations class that I think are really neat. A vibrating string or membrane's motion depends on position and time (a partial differential equation, or PDE for short). To find a solution to the PDE we use the given boundary conditions and initial conditions. I get kind of excited anytime math has interesting physical meaning.
