Glossary
121 terms across 8 fields I actually work in. Every entry opens with one sentence that stands on its own, then explains the thing properly, shows a worked example where the arithmetic matters, and names the misconception that trips most people up. No definition here is a guess — anything I could not state accurately was cut instead.
