Sorry to post it in feedback , i thought i was in math section. But when i posted it in Math section mathmale is removing it thinking it is vulgar :( :(

ganeshie8 · Answer

haha thats hilarious, post it again - provide below link : http://en.wikipedia.org/wiki/Hairy_ball_theorem

anonymous · Answer

I gave him the link, He says there are minors here and it could distract them. Well it's okay anyways , since this is not in our syllabus (obviously). i was looking it for fun to learn something

anonymous · Answer

I came across it here:- https://www.youtube.com/watch?v=B4UGZEjG02s There are some pretty-nice videos of minutephysics watch them in spare time

ganeshie8 · Answer

topology is very hard subject... @BSwan did topology I guess...

anonymous · Answer

Yes I love challenging things :)

anonymous · Answer

I have understanding of some vectors, but i need to learn advanced material on it to digest the things

ganeshie8 · Answer

its an interesting video, ty for pointing it to me :)

Hairy ball theorem says this :
Any smooth vector field on a sphere has a singular point.

anonymous · Answer

Yes it kindoff fits in my intution

anonymous · Answer

Forgive me for the typos i am making

ganeshie8 · Answer

vector fields and other stuff will be taught in vector calculus(calc III)... check out this video : http://ocw.mit.edu/courses/mathematics/18-02-multivariable-calculus-fall-2007/video-lectures/lecture-19-vector-fields/

anonymous · Answer

Yes i will certainly see it! thanks :)

ganeshie8 · Answer

But the usual(recommended) order of learning calculus is this : Single variable calculus (CalcI and II) : http://ocw.mit.edu/courses/mathematics/18-01-single-variable-calculus-fall-2006/video-lectures/ Multivariable calculus (CalcIII) : http://ocw.mit.edu/courses/mathematics/18-02-multivariable-calculus-fall-2007/video-lectures/ Differential equations : http://ocw.mit.edu/courses/mathematics/18-03-differential-equations-spring-2010/video-lectures/

good luck ! :)

anonymous · Answer

thank you so much

anonymous · Answer

I have one more question , will tag you in math section , really basic but interesting one

ganeshie8 · Answer

sure :)

anonymous · Answer

still wanna info ?
but u cant go through topology unless u have good back ground in real analysis so ?
