We also had an very helpful German-to-English translator in Benjamin Unger who kindly did not translate all of the speeches for me.

CORRECTIONS
- 01:24 I say "square numbers" when I mean "even square numbers". First corrected by TheSamuelWells
- A few people have noted that the "clarinet" is actually a "soprano saxophone". I am very sorry to all the music nerds.
- Let me know if you spot anything else!

Filming and editing by Alex Genn-Bash
Written and performed by Matt Parker and Ayliean MacDonald
Blocky animations by William Marler
