Big mouth
Teachers must get credit, too—a lot of credit. They go to all sorts of measures to keep their pupils interested in learning, but they’re rarely recognized for it. The instructor below is a beautiful illustration of that. While demonstrating theorems and proofs in his class, he took things to the next level.
Here’s a sample theorem, “I have a large mouth.” This professor decided to poke fun at the topic instead of going through an intricate procedure, and he kept things light and enjoyable – he knows that’s what keeps students engaged. As a result, he proved that he had a big mouth by fitting his entire fist inside it.
