I have listened to the first 8 lectures (lecture 5 got messed up technically, hopefully will be repeated).
There is no theory in them a graduate student of mechanics does not know, yet still very interesting! He often shows where sloppy thinking may lead into mistakes.
I guess using sympy mechanics will avoid these pitfalls, but then the lectures may help to understand some 'counter intuitive' result of sympy mechanics.
