A conundrum indeed.... :cool: I still don't understand how you can use methods of semiclassical analysis in physics; what does it mean... -
gentzen replied to the thread Graduate So, if RQM isn't consistent; what makes us believe that QFT is?."An Introduction to Hilbert Space and Quantum Logic" by David W. Cohen Seems to be a slim little book, which introduces the math of QM...

gentzen replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.Of course people want to make clear sense of Bohr's obscure words. So they are happy to write things like: But the problem with Bohr is...

Aharonov has been a favorite since at least 2009, now he is 94 -
gentzen replied to the thread Graduate Časlav Brukner, Richard Healey, and von Weizsäcker on the wave function.I have now carefully read section 7 and 8, and then also section 6 which gets referenced there. In my opinion, the stuff that Englert...

gentzen replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.Sounds more like Bohr's "this a meaningless question" to me than Bohr's complementarity. Actually, I think Demystifier interprets...
-
gentzen replied to the thread Graduate So, if RQM isn't consistent; what makes us believe that QFT is?.I didn't even notice that there was a question. But I am actually quite happy that I didn't notice it. Asking three unrelated questions...

gentzen replied to the thread Undergrad Nobel Prize in Physics 2026 predictions.I would love that one, because … well, Aharonov and his academic lineage deserve it :smile:
-
gentzen replied to the thread Graduate So, if RQM isn't consistent; what makes us believe that QFT is?.Relativistic quantum mechanics is not consistent, because it does not allow the creation or destruction of particles. And one can "show"...

gentzen replied to the thread Graduate So, if RQM isn't consistent; what makes us believe that QFT is?.Yeah, distributions, weak solutions, and all that stuff turned out to be interesting and mathematically relevant. And there may be...

Same with me. :smile: Thanks! :smile: That's my way of thinking, in terms of analogies. That's probably the reason why I prefer the... -

Informative.
It was the great achievement of Roy Glauber (and also George Sudarshan) to come up with a framework that gives an absolute meaning to... -
gentzen replied to the thread Undergrad Young's slits with incandescent light source.To this part I can mostly agree. Still, I can see other members here disagree with me, because they would use the word photon...
