Today was busy, and I only fit in about an hour of study, which I dedicated to the next video in 3Blue1Brown’s Lockdown Math series. It turned out not to be closely related to the previous three videos. Instead, it was about the silly idea of an imaginary interest rate and its relationship to a real application in physics. I didn’t find the discussion as enlightening as the previous ones, and I’m afraid my mind wandered. I did learn a bit, though.
For dessert, I watched the video below, an old favorite of mine that I recently rediscovered. I think it’s delightful.
I remember that! Thank you. I love the expressions on the faces of the other people.
