This is a self-study project on solving the Schrodinger equation numerically. It starts from the simplest textbook case I could check by hand and builds up, one new idea at a time, to a problem I ...

A tool for ham radio operators to continuously monitor, log, and publish measurements of powerline interference (QRM). It records audio from a radio receiver, detects the characteristic pulse-train ...

We introduce the heat method for solving the single- or multiple-source shortest path problem on both flat and curved domains. A key insight is that distance computation can be split into two stages: ...
