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.
I've been teaching physics since 2008, and I've spent 5 hard years becoming a physicist. We all here thought about these questions... -
PeroK replied to the thread News JWST may be shut down by DOGE.It seems like you guys are cooked. Cutting funding for science is the least of it.

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.
It seems that you're not here to learn, but to argue. Telling physiscists that they haven't realized the complexity of issue when you...

PeroK reacted to TensorCalculus's post in the thread Hello from an autodidact physicist wannabe with Like.
:welcome: I suspect you are at the start of your physics journey, and quite confident because you have not yet seen the masses you will...

PeroK reacted to Dale's post in the thread B What reference frame is used for the velocity v in the Lorentz transformation? with Like.
Not here. The place for questioning and doubting authoritative theories is the professional scientific literature. PhyscisForums is an...

PeroK replied to the thread B What reference frame is used for the velocity v in the Lorentz transformation?.There are different levels of "doubt". Suppose you started learning pure mathematics and immediately didn't understand mathematical...

PeroK replied to the thread Hello from an autodidact physicist wannabe.There are a lot of retired engineers, especially software engineers, who believe they have a grand unification theory. We get dozens of...

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...
