## AI overview

A guest post introduces harmonic functions through familiar examples involving voltage, temperature, potential energy, fluid dynamics, random walks, and electrical circuits. It begins by relating harmonic motion to oscillations and then connects higher-dimensional harmonics to Laplace's equation.

## Source excerpt

This is a guest post by my friend and colleague Samantha Davies. Samantha is a math Ph.D student at the University of Washington, and a newly minted math blogger. Go check out her blog, With High Probability. If I said "let's talk about temperature and voltage", you might be interested, but few would react the same if instead I suggested an umbrella term: harmonic functions. Harmonic functions are often introduced as foreign operators that follow a finicky set of rules, when really they're extremely natural phenomena that everyone has seen before.
