Math
Miscellaneous
- Gower Twitter thread on thinking you've found a great result, but you made a mistake (2021).
- Shannon's math camp notes on analysis, etc.
Math Education
- My StackExchange question on synthetic division and whether it is every useful for anything.
Irrational Numbers
- I read that Kronecker opposed the use of irrational numbers because they can't be constructed from integers by a finite number of steps. But you can construct pi as the ratio not only as an infinite series, but as the ratio of circumference to diameter. What's wrong with that?
