Trivia
The names, facts, and curiosities every mathematician collects.
Mathematics has a history, a cast of characters, and a stock of names, constants and famous results that every mathematician picks up eventually, mostly by accident.
These questions cover notation and where it came from, constants and their values, famous theorems and open problems, and the people behind them. They are short by design — a warm-up, or a way to fill in the gaps nobody teaches directly.
