Who dislikes a video like this? It seems to me anybody who finds such a specific video on mathematics would be content to have a lecture of any form about it.

These lectures require quite a bit of tensor calculus. I recommend xylyxylyx or eigenchris, they each have comprehensive series on this subject and cover quite a bit more than the scope of this lecture too.

If you want to understand general relativity, if you know multivariable calculus, I would recommend starting with Leonard Susskind's lecture on GR.

These are graduate level topics usually done in Differential Geometry--iii course. So if you dont understand anything its ok. I would suggests the following good reference for differential geometry and relativity but still you need to go through a lot of stuffs in order to get it: books.google.de/books/about/An_Introduction_to_Riemannian_Geometry.html?id=oV4qBAAAQBAJ&printsec=frontcover&source=kp_read_button&redir_esc=y#v=onepage&q&f=false

Конечно. Если у вас есть осмысленный вопрос в этой области, или же лишь знаете названия и смысл главных понятий (хотя-бы и приблизительно) тогда вы найдёте и с пользой отслушаете. Что же касается языка доклада, кажется, что без него продвигаться в науке весьмя затруднительно. Сам доклад производит впечатление сверки часов. Докладчик даёт отчёт о том, что почти всем слушателям известно. Суть в методике представления. Попадает под "сверка часов".

Interesting that you first say you are unable to understand a beautiful lecture but then offer advice ... huh!? Covariant Derivatives are a fundamental requirement for undergraduate-level electrical engineering curriculums. First view this video (miss the comedy at the beginning of the video kzbin.info/www/bejne/g4C2p2N8h5yZiLc ) and then come back to this beautiful lecture and you will understand.

You are not a divulgator, man! And I understand you don't mean to be one. Otherwise you wouldn't have forgot to tell what the prerequisites are for understanding your lecture. You appeared to me - I apologize for that - as just someone who likes writing on a blackboard as fast as possible. Why, prof, why are you doing that?. You intented to help the uninitiated? Clearly no. In what way you can help those who have some knowledge in the field? Who can read all that in a book? Is yout video better a a book (maybe written by you)? Really, I don't get it. I'd like if you explained it to me.

@Cosmic Landscape Nothing intrinsically bad about "hyperbolicity". The problem is with people, who use it to get away with (what was it one was getting away in an English idiom?...) by using it in dynamical systems and control theory. Otherwise is so full of beautiful symmetries. Some people got carried away by the insight and think they are gods, which I don't like.
