A friend of mine (way older than me) has been following The Theoretical Minimum video lessons by Leonard Susskind. I have read all the questions here about resources on Classical Mechanics and note that I am not searching for books, but just video lectures.
Now, he'd like some more.
Specifically, he enjoyed the Classical Mechanics lessons (Lagrangian, Hamiltonian) and before moving to GR he wants to follow some deeper lessons.
I have no idea if and where such video (free) lessons could be found, and if they are at par with Susskind's lectures. My only concern is not to suggest a course (or some courses) that assumes too much knowledge from the spectator (I don't think he knows anything about differential geometry, for example, but I know he could manage to follow additional courses).
