Like.
Then you should leave assessments of difficulty to them! Even tests of Bell inequality violations are hard to realize, in the sense that... -
PeterDonis reacted to Demystifier's post in the thread I Question about discussions around quantum interpretations with Like.
You mean a local hidden-variable theory cannot reproduce all of QM's predictions. A non-local hidden-variable theory can.

PeterDonis reacted to A. Neumaier's post in the thread I Question about discussions around quantum interpretations with Like.
Yes. That's the part where interpretations differ. This is because standard QM ignores all preparation issues and detection issues...

Yes. The evolution of the radiated system in a homogeneous medium is generally assumed to be unitary, with an effective dynamics...

My arguments are not specific to a particular setting. In an ion trap, one can prepare a single ion in an excited state and wait until...

This is simply wrong. A probe of a pure, weakly radioactive, crystalline substance consists in the traditional models of a huge number...

PeterDonis replied to the thread I Energy*time uncertainty for particle decay.I'm not sure you can even do basic QM if you don't know at least some linear algebra.

PeterDonis replied to the thread I Energy*time uncertainty for particle decay.That wouldn't make the question answerable. Also, a homework question is best posed based on an actual homework question, i.e...

PeterDonis replied to the thread Help me understand why “Block Universe” is not scientifically proven.If you can find a published reference (textbook or peer-reviewed paper), we can discuss this in a new thread. I'm closing this thread...

Me again. Just felt like writing again to appreciate your patience, and to kind of explain where I was coming from after you've helped...

PeterDonis replied to the thread I Gravitational self-interaction: another attempt to replace Dark Matter.This has nothing to do with what the paper under discussion in this thread is proposing. Please don't clutter the thread with off topic...

PeterDonis replied to the thread A Twistors and celestial holography.Oops, that's true. @Physics Detective sorry I got mixed up about that. But it's still true that this is an "A" level thread, so...

PeterDonis reacted to PeroK's post in the thread I What Are the Limits of the Universe According to Cosmologists? with Like.
The NG article is not worth reading. According to Introduction to Modern Cosmology by Liddle: The Big Bang model is reliable back to...

PeterDonis replied to the thread A Twistors and celestial holography.You did mark this thread as "A" level. [Edit: sorry, I was mixed up about that, see later post.] That means it involves graduate level...
