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 are people who do not want humans around social media. They want social media to be used mostly by bots. They want the only ones on social media to be people who fund those who program the bots, etc.All politics.
Thanks for this educational contribution . Ricci' s curvature in fluid topology and string theory , node and categories , geometric entropies and combinatory too .
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.
I understood nothing other than a vector. M n high school guy and I came here to get some help understanding general relativity. But I was dumb all over
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
You have to know already what he is talking about. Then its quite entertaining. If you dont know what a manifold, metric, etc. is then its a waste of scarce life time.
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 th-cam.com/video/MOSv0FR7fRU/w-d-xo.html ) and then come back to this beautiful lecture and you will understand.
@@chymoney1 I grant you that but isn't it the point that we want to create a manifold with n-dimensions? To publicly dismiss the great John Morgan when one themselves is unable to understand the man is disappointing to say the least.
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.

Probably some of those are bad taps on phone screens. Or maybe people who are trying to indicate to YT they aren't interested in videos like this.
@@ian_b I pressed dislike because I dislike his rhetorical questions and such questions in general lol
Don’t care about them. They make themself hilariously.

Their brains overloaded then they disliked
J.W.Morgan is a great mathematician and a great lecturer too.
Thank you for sharing this well-structured and pointed lecture!
This video makes me smarter.I would like to know more things about ricci flow.thank you for uploading this

Riemann was a genius
He certainly was.
He was definitely underrated genius.
im completely in the dark with this... but im also intrigued and blown away by it.
Thank you for posting the lectures!
Just Beautiful.
Hey
Can anyone share the whole playlist of this lecture series?
What are the prerequisites for understanding this course? (I just finished the mathematic analysis and linear algebra course)
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.
@@JacobGaiter thank you
me:professor! prof: yes? me:how did i come here from a beach party video?
C'est un cours bien détaillé
C'est bon pour toi, non?
can anyone tell what is the prerequisite to read what is taught in the lecture?
aman ku Differential geometry and manifolds and some exposure to basic Riemannian Geometry.
What are the Prerequisites of these lecture series?
You should be familiar with some differential topology, mainly a large number of definitions.
Thank you very much!
Is there more lectures?
Part 2: th-cam.com/video/yqwlAOTUKGc/w-d-xo.html
So Ricci Flow is not a rapper?
Who is the speaker, great content and so well explained... thank you for posting
good lecture!
Nice
A primary school lecture in the Soviet Union comrades!
Stop talking nonsense.The Soviet Union was long dead by then!
I understood nothing other than a vector. M n high school guy and I came here to get some help understanding general relativity. But I was dumb all over

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

Watching 40 seconds of this and I already feel like I can skip a couple of grades. And I don't even know how to pronounce the topics name right.
very complicated
Ah yes i understand some of those words lmao.
never use water on a chalk board.....
Bir şey anlamadım ama olsun
The idea is evident, but the scripture does not make any sense. 🕯📜✍️🏼
Frustrating lecture. It will be more better to read books on this topic. But I appreciates at least he (Sir) dares to explain the Riemannian Geometry.

Rory Lewis well that’s because many people take the derivative without ever having to learn its convariant

@Cosmic Landscape And yet it has to do with social setup. Spencerianism and Trotskyism are setting us socially up on a manifold of negative curvature.
