PeroK reacted to Herman Trivilino's post in the thread A Charge to mass ratio of a photon with
Like.
Charge to mass ratio applies only to particles that have both charge and mass. It makes no sense to speak of the charge to mass ratio of... -
PeroK reacted to PeterDonis's post in the thread I Does action at a distance violate any conservation principles? with Like.
But such influences are not directly observable. All directly observable results are in accordance with standard QM. Standard QM obeys...

@Hornbein What guys like that could do with an upright bass is awesmacking. On electric bass I do like Chris Squire, but he has plenty...

PeroK reacted to vela's post in the thread Need a book on Modern Physics to supplement Griffiths QM with Like.
Then I think it would help, as @robphy suggested above, if you could give us an example of a roadblock you're running into. Maybe you...

PeroK replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.Nature laughs at the difficulties of integration!
-
Thank you, that's a big help. And 31 minutes I'll get back!

Yes. I've just come across "clanker" myself recently. I think it's awesome. And then I remember that we are going to have to live...

PeroK replied to the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it?.Even the two body problem only has an analytical solution in terms of the shape. There's no closed form solution for the position as a...

PeroK reacted to physicistwithaheart's post in the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it? with
Sad.
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are... -

PeroK reacted to JimWhoKnew's post in the thread A Eigenstates of the Klein Gordon Field Operator with Like.
The referenced derivation (stackexchange) uses the continuum expansion, but relies on the discrete commutation relations...

PeroK reacted to JimWhoKnew's post in the thread A Eigenstates of the Klein Gordon Field Operator with Like.
Welcome to PF (I should have written it in #2). ##a+a^\dagger## is proportional to ##\hat X## , so the eigenstates are just...

Speaking of research papers, it does seem like analysis and experiments on how the the current approach of step-wise reasoning or "chain...
