The more I teach, and the more I play music, the more I think the role of the professor is primarily to teach students how to become experts at practicing.

Been trying to understand the inscribed square problem. Here is that journey.

Let's start with a closed loop that forms a cow and instead of a square, try to form a rectangle. If the diagonals have the same midpoint and length, then we have a rectangle. (1/n)

New* video! If you’ve ever wondered what topology is, this problem is one of the best examples I know of to give an authentic sense of what it’s all about: https://t.co/YKZXcjoJ8l

Here's a fun little "magic trick." Can you figure out how it works? Hint: even and odd numbers. I was thinking you could roll a die to determine how much to count each time. (I saw the trick was credited to Martin Gardner—true? Source?) https://t.co/mXfD765mcW
