PeroK reacted to weirdoguy's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with
Like.
No, it proves you didn't understand both theory of relativity AND answers you've been given. Read them again. -
It's an old thread, but since it was revived, The attraction between objects with same charge sign is one of the reasons why the...

PeroK reacted to Steve4Physics's post in the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring with Like.
Yes, but the equilibrium position is not relevant. It’s essential to realise that to find the minimum value of ##F##, we must consider...

PeroK reacted to Lincon Ribeiro's post in the thread B Why is the 3 body problem unsolvable? And what will happen if someone solves it? with
Informative.
This is one of the most interesting problems in the history of physics, and, adding to other replies, there are several steps between... -
PeroK reacted to Dale's post in the thread I What does equiprobable mean in the context of thermal motion? with Like.
Here is a more realistic image: The main thing wrong with this image is that it is 2D and this kind of motion happens in 3D, and also...

PeroK replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.If ##m_2## does not move, then that gives a maximum possible extension of the spring, based on Hooke's law. That gives a maximum value...

PeroK reacted to haruspex's post in the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring with Like.
To move the other block, just, you need the point where the spring is at max tension. Since the other forces on m1 are constant (as...

PeroK reacted to russ_watters's post in the thread Study: Social media probably can’t be fixed with Like.
Topic restriction does help, and over time we've narrowed the focus, eliminating politics, philosophy, "theory development" and...

PeroK replied to the thread A Crisis for Newly Minted CompSci Majors -- entry level jobs gone.It all depends who's paying. If you are clever enough you get the customer to pay for the bug fixes!

PeroK reacted to sonnichs's post in the thread I Software for entering Mathematics Equations with Like.
Thank you for your replies. I can see the value of LaTex--a lot of people use it now. (I was born pre-sputnik) I am still looking thru...

PeroK reacted to Filip Larsen's post in the thread Study: Social media probably can’t be fixed with Like.
I know exchanging movie memes and preferences always seem to bring people together, but as the the OP (for once) I would like to...

PeroK replied to the thread Study: Social media probably can’t be fixed.If the platform cannot identify who wrote it, then it is responsible. Someone, for example, would be able to charge X with making a...

PeroK replied to the thread Study: Social media probably can’t be fixed.I've believed from the beginning that any platform, whether TV, print or Internet must ultimately be responsible for everything they...

You are welcome. However, now I feel compelled to iterate my position that this unfortunately this does not address any of the...

This is not, strictly speaking, a discussion of interpretations per se. We often see discussions based on QM as it was understood...
