In 1655 the English mathematician John Wallis published a book in which he derived a formula for pi as the product of an infinite series of ratios. Now researchers from the University of Rochester ...

I had planned for part 2 of this series about π to be about the classical area formula for the circle, but then something new came up. Well, by new I mean a new proof of something old, and it's a ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
