These videos have totally increased my understanding of vector calculus - I'm no longer just doing the trick but I'm actually manipulating the maths. Thanks MIT.
It does - there is a generalized Stoke's theorem of which the Divergence Theorem, Green's Theorem, Stoke's theorem as it appears here, and the Fundamental Theorem of Calculus are all special cases. This generalized theorem works in any dimension!
Great video. I kept wanted to walk away instead of spending 50 minutes on YT, but each new topic was very relevant. Ended up watching the whole damn thing. Thanks p.s. I agree. That chalk is pretty sweet.
The ideas for the proof of the Stoke theorem make me remember the way Maxwell argued about the existence of micro currents in a magnetic shell (a kind of imaginary surface) which cancel each other so that they're equal as a single current circumventing the magnet, and thats why you can recreate a magnet with just a single electric current in a loop... then i realized that the Stokes theorem is used in Maxwell equations... wow hehe
This is unfair to your teacher because on any material that you have previously previewed, you would understand it much more quickly. So your teacher acted as a first learning of the material, and this video acted as a second viewing of the material. That is why you feel like it is so much easier to understand.
However, I watched these videos first and then attend the lectures in my own university only to find that professors at MIT indeed conveys knowledge in a much more easy-to-understand way. I'm not saying that my own professor is inferior to any other professor in academic field; what I want to claim is that my professor frequently and unintentionally complexify the knowledge and in turns scares the students "away" and I think is the point is that lecturers should be reminded that using geometric interpretation or other intuitive approach doesn't contradict with rigorous mathematics.
EPIC AUTO-BLACKBOARD @ 2:35 And that chalk sounds really soft, the stuff my teacher uses is all hard and you can hear the scratching ;_; Oh and thanks, this is really helpful for my final next week :P
Thanks.That's gonna be interesting. I was wondering how the concepts such as curl(F) can be extended to high-dimensional scenarios and also whether all the geometrical interpretations remain.
Actually as you seen in the lecture curl is defined as the cross product between the del operator and the vector field.The problem here is that the cross product is defined only in 3D(and 7D ),so I am also wondering how curl generalizes to higher dimension other than 7D
I didn't know it had some special meaning in 7D, but there is a way to cross product n-1 vectors in n-dimensional space. And this may align with the generalized Stokes' Theorem in n-dimensions
Theres a problem on the website about this: look ocw.mit.edu/courses/mathematics/18-02sc-multivariable-calculus-fall-2010/3.-double-integrals-and-line-integrals-in-the-plane/part-b-vector-fields-and-line-integrals/session-64-curl/MIT18_02SC_pb_64_comb.pdf
Do you think he purposefully stopped erasing boards while they were coming down simultaneously so that the students wouldn't cheer? Because throughout the lecture series it seemed to progressively happen less and less which makes me sad.
It does actually, there's a generalized Stokes' Theorem for an n-dimensional surface and (n-1)-dimensional boundary. The thing is, it uses more complicated terms but it aligns with Stokes' on 3D space (and even the Fundamental theorem of calculus in 1D!)
@@00TheVman the way it was described to me was Stoke’s theorem generalized is “The change of something on the outside is the same as the sum of the change of everything inside” or essentially if you find the change in a boundary it’s the same as the sum of all exterior derivatives, which gives nice formulas in lower dimensions like the Fundamental Thrm of calculus, Stokes, and Divergence

The camera work on these lectures is great.
the guy who filmed these videos must by now be the best engineer of all times...
I have a math degree and I still enjoy these lectures. Auroux is a great lecturer.

I love these lectures. He makes it so easy.
Great video.

p.s. I agree. That chalk is pretty sweet.
thank you!!!!! so in love with this class :)
thank you al lot prof. Denis Auroux... you are a great lecturer
Man I wish my college had those blackboards. Nah, I kid - MIT rocks! I wish I had this professor!
The ideas for the proof of the Stoke theorem make me remember the way Maxwell argued about the existence of micro currents in a magnetic shell (a kind of imaginary surface) which cancel each other so that they're equal as a single current circumventing the magnet, and thats why you can recreate a magnet with just a single electric current in a loop... then i realized that the Stokes theorem is used in Maxwell equations... wow hehe
what other lectures does this amazing lecturer have?
Seemed sooo difficult in class today......now i understand why they are so good at MIT. Such a great teacher....Make it look easy.

48:14 that guy totally knew he was blocking the camera
38:08 very impressive proof
EPIC AUTO-BLACKBOARD @ 2:35
And that chalk sounds really soft, the stuff my teacher uses is all hard and you can hear the scratching ;_;
Oh and thanks, this is really helpful for my final next week :P
Guaranteed everybody watching this has a final tomorrow
No, I don't
dude i am in 9th class learning this for fun
Quality teaching!
Thanks ❤️🤍
Top teacher.💯💯 Usually scholars don't teach that well.😅😅😅
This is helpful ❤️🤍
19:40 if you turn the volume down everything he says changes its meaning
Thanks.That's gonna be interesting. I was wondering how the concepts such as curl(F) can be extended to high-dimensional scenarios and also whether all the geometrical interpretations remain.
He writes nicely.

question, why does curl come out twice the rotational speed
Theres a problem on the website about this: look

Do you think he purposefully stopped erasing boards while they were coming down simultaneously so that the students wouldn't cheer? Because throughout the lecture series it seemed to progressively happen less and less which makes me sad.
I wonder if Stoke's theorem generalizes well to even higher, say, n, dimensional space.
It does actually, there's a generalized Stokes' Theorem for an n-dimensional surface and (n-1)-dimensional boundary. The thing is, it uses more complicated terms but it aligns with Stokes' on 3D space (and even the Fundamental theorem of calculus in 1D!)

what is the text book for this course
We used m,n, and p.
Genius. Fantastic.
20:55 Does that.......make sense? hehe
As viewed from above
I can assure that, he has that frenchy accent specially when saying zero
@HikariOfTheAzureSky
Google says France, yes.
He is very interesting
yes
Cilindet
is he french?
Yes, definitely
Cross product is easy.
@fprecoiil math is easy if you have a good professor

"Except that at that time we called things M&Ns"
....a huge lecture hall..but the instructor has to use chalkboard to write notes!!!
Is it just me who hears poof everytime he says proof
@Brotrr and a sweet ass chalkboard
I have a math degree and I still enjoy these lectures. Auroux is a great lecturer.
