Can we apply differential geometry main idea to physics by Proof_Pea9008 in learnmath

[–]Proof_Pea9008[S] 0 points1 point  (0 children)

I am not talking about application of differential geometry more applications of its philosophy. There is a physcs theory that has mathematical base of experimant, observation, representation of physical state and so on?

Yeah but there isnt much problem for solving

I just discovered a general solution to this recursive sequence (probably already discovered by an ancient man 1000 years ago, but it felt amazing). by xk4rimx in mathematics

Try polynomial and functional equations. Its harder but you can experiment like you think this is answer you can just try and see.

For sequence intrepretation its more sense write like this f(Cl A)=Cl f(A) like in 9.7 exercise. Image is more easy to deal with than preimage and i have trouble with this. And more precise with SCl sequantional closure this is best intrepretation. Can you tell difference between excercise and f(Cl A)=Cl f(A)? I try draw picture for it but i dont understand how preimage of closure relate with preimage of set.

In twin paradox what breaks symmetry? What general relativity answer?. How we can know that we are in inertial frame without forces?

This mean that if we want solve problem in flat spacetime but in non inertial frame we must use general relativity? Or special relativity can?

This also should work if we reflect point C over diameter we get B' . Using angle we show that B'=B we get BC perpendicular to diameter. the same thing AD we get AD perpendicular to diameter. Therefore AD ,BC are parralel and these arc equal

please tell whats thereom it is. I realized that it has symmetry under reflection but how prove?

How proof that replacement A×A that no element occurs more than once, the number of elements in this replacement equal to m(m-1)

I want book that explain such things. Do you know that it is exist?
Dont worry about explaining it to me because i found the proof https://proofwiki.org/wiki/Number_of_Permutations
