This thread has highlighted that ultimately it is perhaps a matter of personal taste whether "nature is fundamentally probabilistic" or...

I think you have it somewhat backwards. In a typical quantum experiment, we prepare a system, it goes through some kind of process, and...

The obvious point is that you are not working on a specific problem, but on a grand unification of everything. If you were doing your...

Haha! I love both of course! :smile:

Physics books hopefully and not pulp fiction.

Hi everyone, I'm just a physics enthusiast. I took some first-year courses a long time ago, but I wasn't able to continue, so I don't...

Here it is (note that this is an Advanced, research-level paper). It might be useful to see that physics isn't just about having an...

The best model for the universe suggests that its expansion will continue forever. There's no evidence that the universe will...

My name is Anureet i am high schooler from India and i absolutely love physics a lot. Just want a community where i can discuss and...

:welcome:

Just to note that, in my opinion, that way of teaching/demonstrating the relativity of simultaneity is extremely clumsy, with several...

This is shown in Jackson's 2002 paper "From Lorenz to Coulomb and other explicit gauge transformations" (Am J Phys, 35:832-837)...

Hello and :welcome: ! I have recently searched for instances in physics that were suited to be an example of independent research. I...

Let me show you the alternative way to solve this problem, using vector components. We'll let ##\vec v_1## be along the positive...

Those are speeds. Speed, by definition, is the magnitude of a velocity. The original statement of the problem is sloppy in using...
