PeroK reacted to jjson775's post in the thread I Energy*time uncertainty for particle decay with
Like.
My question came from a homework problem from Modern Physics, Serway Chapter 5, Matter Waves. Yes, not a real QM textbook. -
PeroK replied to the thread What Determines the Minimum Mass of Block B for Movement on an Inclined Plane?.I thought the point was that (depending on ##\mu## and ##\theta##) block B will initially slide down the slope, considerably...
-
PeroK replied to the thread I Question about discussions around quantum interpretations.I thought I was taking more an experimental view of establishing which components appear to influence the probabilities of the outcomes...
-
PeroK replied to the thread I Question about discussions around quantum interpretations.I don't have a specific interpretation in mind. My point is that, generally, the evolution of a superposition can be considered the...

PeroK reacted to JimWhoKnew's post in the thread B Is a table levitating possible, even at a minuscule probability? with Like.
The assumptions of Statistical Physics say that the probability is extremely minuscule. How do we know it is true? We don't. But the...

PeroK replied to the thread B Is a table levitating possible, even at a minuscule probability?.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...

PeroK reacted to Demystifier's post in the thread I Question about discussions around quantum interpretations with
Informative.
I think I see now where is the problem. Many people don't understand very well how randomness arises in classical deterministic... -
PeroK replied to the thread What Determines the Minimum Mass of Block B for Movement on an Inclined Plane?.Okay, that complicates things somewhat! Are we sure block B is not supposed to be sitting at the bottom of the ramp?
-
PeroK replied to the thread I Question about discussions around quantum interpretations.Yes, but those are probabilities that can be resolved by more knowledge. Determinism means you can get rid of the probabilities with...

PeroK replied to the thread What Determines the Minimum Mass of Block B for Movement on an Inclined Plane?.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...
-
PeroK replied to the thread I Question about discussions around quantum interpretations.I understand the argument. We possibly risk going round in circles and it becomes a debate about the definition of randomness. Here's...
-
PeroK replied to the thread I Question about discussions around quantum interpretations.The question is whether those uncontrollable stochastic features are fundamental to the statistics of the outcomes? Standard QM allows...

PeroK reacted to A. Neumaier's post in the thread I Question about discussions around quantum interpretations with Informative.
Yes. The evolution of the radiated system in a homogeneous medium is generally assumed to be unitary, with an effective dynamics...
-
PeroK replied to the thread I Question about discussions around quantum interpretations.If I understand what you're saying, that sounds like the complement of @Demystifier argument. We start with a macroscopic system that...

PeroK replied to the thread I Question about discussions around quantum interpretations.I didn't realise it was impossible to prepare a single radioactive atom and measure its decay time. If so, then I'd need a different...
