anuttarasammyak replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.My 2X2 case study is an easy example to support it. Exchanging j=1,2 does not change the matrix elements. I suppose in n x n matrix... -
anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.Now we know that the stress tensors T, T1, and T+T1 are all symmetric in post #17.

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.You express one of stress tensor in surface integral and the other in volume integral. Then in angular momentum calculation you make the...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.We know the whole tensor is symmetric. In mathematics no symmetric tensor is expressed as sum of symmetric tensor and non symmetric...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.Thank you so much for very kind explanation. I still do not find the evidence of this division. The microscopic view denies the...

anuttarasammyak reacted to Klaus3's post in the thread A Conflicting results about Stress tensor symmetry on EM field with
Like.
Microscopically speaking the distinction doesnt exist. ##T## is supposed to account for contact forces. So forces between particles... -
anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.Say ##T_1## comes from EM, where does ##T##, which you say symmetric, come from ? I am not a specialist of materials at all so take it...

anuttarasammyak replied to the thread I Example of complete set of operators.Now I have got a right idea in the wording. Thanks.

anuttarasammyak replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.##A## and ##D## do not share eigenvalues as posted #14. Even so, is diagonalization by ##P## useful ? In case that real A is a normal...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.Can a body force have stress tensor part ? There seems to be contradiction in words. Maybe a contradiction causes another...

anuttarasammyak reacted to DrChinese's post in the thread I Physicists disagree wildly on what quantum mechanics says about real… with Like.
You’re probably thinking “duh”. But that’s actually the title of the article that was published yesterday. Physicists disagree wildly...

Local balance is simply the statement that results when you drop the integral signs, by saying that the integral equation is valid for...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.I see that "local balance" means taking a look at dyamical equations not in coordinate integral forms. Thanks. For simplicity let body...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.The two equations are equation of motion and equation of angular momentum. They evolve with time. What do you mean by "local balance"...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.According to post #3 Maxwell stress tensor in media, especially anisotropic media, seems to be your issue. Let me say about a tiny...
