Why?
Because its the definition of a symmetry, you only change the configuration space

SimoBartz
configuration space?
you mean the space of the degrees of freedom=
?
and conjugate momentum

Sorry phase space. If x,p to X,P you must have H(x,p)=H(X,P)
SimoBartz
SimoBartz
ah ok
it makes sene
sense
thankyou!

You aren’t allowed to modify the hamiltonian

this conversation is really helpful for me, i'm an autodidact in physics

Once again, a full unfying model would incorporate the em field in the phase space thus reinstating rotation invariance. One such model would be QED in QFT.
Cool, you’re really motivated to arrive this far on your own!
SimoBartz
SimoBartz
yes i understand what you mean now. It should be like considering the em field as a system with its own degree of freedom coupled with the dipole

I’m sorry though I’ll have to leave (it’s 2:00 am in my timezone :p). Why don’t you leave your question in the chat and I’ll answer them tomorrow?

I don’t know how to render math on these apps though
