Hi,

I don't remember seeing these videos recommended here in the past.  Grant
Sanderson's 3blue1brown website (and youtube channel) is filled with
beautiful, insightful, perfectly lucid videos on a variety of topics in
math and physics.

Here are two that I have been watching lately.

This one is about Feynman's proof that orbits are ellipses:

And this one, with Professor Steve Strogatz, presents a elegant solution of
the brachistochrone problem:
