/sci/ - Science & Math

Hi /sci/, I was wondering if any of you, could recommend me a good online lectures site (or a Youtube channel or whatever), about maths and physics as a reinforcement to my regular study schedule (and because I cant find any decent movie to watch).

I'm specially interested in multi-variable calculus, but what I've found on Youtube (UCBerkeley and MIT channel), seems too basic, and somehow different to the way I'm being taught this, which is heavily based on numeric topology (balls, etc), with a lot of pure abstract definitions.

Thanks (I know you'll probably tell me that I should keep my basic stuff to myself, but I guess a lot of people could find this information useful, specially my faculty, who I'll probably share your links with).

I'm doing Aerospace engineering , and it's actually a pain in the ass most of the time.
Basically a shitload of maths physics and fluid mechanics everywhere.
Actually during de first 2 years you'll rarely see or touch anything that flies or is supposed to.
And it's much more air than space oriented most of the time.
(at least where I'm studying)

As you might notice I'm a bit disappointed with the career, but it might have something to do with the fact I just came home after a fucking 4,5 h semestral exam.
