Odds and Evenings
A podcast about mathematics, puzzles, numbers and games
About the show
Playing around with maths and puzzles was something that the two hosts spent their time at university doing together. Now in their late twenties with proper grown up jobs, Alaric and Alex carve out the occasional evening to sit back and smell the numbers. Not all of the mathematics is entry level, but they envisioned this podcast for those people whose science degrees may be long behind them, but who still get a kick out of recreational numbering.
If this is your first time listening, episode 4 is a good representation of the show as a whole and can be used as a jumping on point.
