Like.
You’re probably thinking “duh”. But that’s actually the title of the article that was published yesterday. Physicists disagree wildly... -
anuttarasammyak reacted to Klaus3's post in the thread A Conflicting results about Stress tensor symmetry on EM field with Like.
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...

anuttarasammyak reacted to Klaus3's post in the thread A Conflicting results about Stress tensor symmetry on EM field with Like.
This expression for the maxwell stress tensor only works for linear dielectrics or monopolar bodies. It is not necessarily symmetric for...

anuttarasammyak replied to the thread A Conflicting results about Stress tensor symmetry on EM field.Explicit expression of Maxwell stress tensor shows obvious symmetry. I do not understand your situation introducing other stress...

anuttarasammyak replied to the thread Calculating the Planck Length.Your estimation would show that we have minimum length, which is order Planck length, for our investigation of space. When we try to...

anuttarasammyak replied to the thread I Can one find a matrix that's 'unique' to a collection of eigenvectors?.I don't think that the diagonalization is possible in general. In the case of normal matrix A, it is.
