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 ...

But it's not 1995 any more. Numerical calculations aren't out of reach of beginning students. They aren't even out of reach for physics faculty. Now we have the following excellent tools.

Numerical calculations are grand. Of course, they are just another form of normal calculations - like I have said before.
