Question about discussions around quantum interpretations
.
I don't agree with that at all. And I don't know how many physicists would. In all of physics you do calculations based on certain...

Energy*time uncertainty for particle decay

That said, I'd be wary of putting too much emphasis on either QM or SR, as presented in a general physics book. For me, both these...

I don’t know what “basic QM” is but am happy to have gained some insight into quantized energy, wave particle duality, the Schrödinger...

You have to go for it and learn and study matter waves if that's what the book does. Matter waves were part of an early version of QM...

My question came from a homework problem from Modern Physics, Serway Chapter 5, Matter Waves. Yes, not a real QM textbook.

Minimum mass of a block

I thought the point was that (depending on ##\mu## and ##\theta##) block B will initially slide down the slope, considerably...

I don't have a specific interpretation in mind. My point is that, generally, the evolution of a superposition can be considered the...

The assumptions of Statistical Physics say that the probability is extremely minuscule. How do we know it is true? We don't. But the...

Or, a fair coin coming up heads 200 times in a row. Or, a pack of cards being randomly shuffled into a given configration. Even these...

I think I see now where is the problem. Many people don't understand very well how randomness arises in classical deterministic...

Okay, that complicates things somewhat! Are we sure block B is not supposed to be sitting at the bottom of the ramp?

Yes, but those are probabilities that can be resolved by more knowledge. Determinism means you can get rid of the probabilities with...

I don't see the problem here. All the analysis is just to convince you that the simple approach works: calculate the force needed to...

I understand the argument. We possibly risk going round in circles and it becomes a debate about the definition of randomness. Here's...
