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...

In mm/dd/yy format, 9/16/25 is 32/42/52. In dd/mm/yy, it's 42/32/52, still Pythagorean, but not monotonically sequential.

PeroK replied to the thread RIP Robert Redford (89).That was one of the great Oscar travesties. Ordinary People over The Elephant Man and Raging Bull?! Best director and best picture?!

PeroK replied to the thread I Question about discussions around quantum interpretations.I'm back in London, so I'll read your paper today. I'm not convinced that a coin is a good analogy for a quantum system, like a spin...

PeroK reacted to Herman Trivilino's post in the thread I Energy*time uncertainty for particle decay with
Like.
I would love to see that if you can dig it up. -
https://www.newsweek.com/robert-redford-dead-hollywood-live-updates-2130559 Apparently Redford was a somewhat poor student, so was...

It might turn out to have a non-zero curvature. But if it truly has a zero curvature we will never be able to confirm that it is not...

PeroK replied to the thread I Energy*time uncertainty for particle decay.A lot of what passes for QM in non-specialist courses is a messy hybrid of QM and classical thinking, IMHO. If I could explain why...

PeroK replied to the thread I Energy*time uncertainty for particle decay.I found a video of an Indian physics professor exploding this myth for his students. He knew they would all have learned the "old"...

The position-momentum uncertainty principle is alive and well. I don't know the history, but certainly one still sees the erroneous...

PeroK reacted to PeterDonis's post in the thread I Energy*time uncertainty for particle decay with Like.
I note you say (classical). Those textbooks are not focused on QM; they might cover it, but they're not primarily QM textbooks. Which...

PeroK replied to the thread I Describing the Big Bang.The NG article is not worth reading. According to Introduction to Modern Cosmology by Liddle: The Big Bang model is reliable back to...
