Perhaps thats because QFT does not reduce to ordinary QM: https://arxiv.org/abs/1712.06605 Thanks Bill

When I was younger, I would grind through the details. I even taught myself Rigged Hilbert Spaces (it took some time) to understand Dirac's methods from his textbook and von Neumann's in his textbook, which was just an extension of Hilbert spaces I studied in my math degree. In hindsight...

Dale's answer is, as usual, excellent. However, after reading the link I posted a natural question is what is the wave function of a photon? That is quite deep: https://arxiv.org/pdf/0708.0831 Thanks Bill

If you want the gory technical detail, see: https://digitalcommons.usu.edu/cgi/viewcontent.cgi?article=3211&context=physics_facpub Be a bit wary, though, if you want to verify all the math. While a worthwhile exercise, some people have found it 'hard' going. You may need to post a question...

I think it's fine as is. It is obviously 't Hoof's view and those following the thread should become acquainted with it, if they aren't already. Personally, I think he is on the wrong track; incomplete would be a better description (which was Einstein's final view), but it is only one of the...

I would prepare by actually studying AI, which, while of course time-consuming, fortunately can be done by anyone from home (with reasonable preparation in calculus, linear algebra, and probability): https://www.colorado.edu/cs/academics/online-programs/ms-artificial-intelligence-coursera Of...

Available in Audible as well as one of the 10 free books if you are a member, as I am. Thanks Bill

FIRE is viable here. I did it, and I know others who have. In fact, getting a job over 50, or even 45, is next to impossible if you're laid off, so, as a practical matter, regardless of marriage (especially with children), it's a wise choice. Those into it; mostly these days dollar-cost...

Having worked for the Child Support Agency for 15 years, take my word for it: marriage is a lottery fraught with danger. I would only ever suggest it, and having a family, to those into FIRE (financially independent, retire early), and I'd advise waiting to have children until both are...

Actuaries of my acquaintance tell me it is no longer 'the best job in the world' it was in the past. Some senior Fellows of the Actuarial Society are jumping ship and moving to Data Science and AI. At a local university (Bond University), the Actuarial Science degree has a double major in...

The answer depends on the interpretation; for example, in Bohmian Mechanics, particles are separate in the classical sense. In the formalism of Quantum Field Theory, two entangled particles are a single 'excitatIon' of the quantum field. If you observe it with the particle number operator, you...

It's chapter 3. It's based on the classical POR, specifically that the probabilities are frame-independent (it breaks down relativistically). Thanks Bill

Can you let us know where you live? I know Australia well, the US fairly well, and have an OK knowledge of the UK. In Australia, we now have actual degrees in Quantum Physics eg: https://www.uts.edu.au/courses/bachelor-of-advanced-science-physics-and-quantum-technology Personally, though, I...

One issue rhat confuses some is what is called specialist math here in Australia included a significant amount of classical mechanics when I did it way back when. I suppose one could call it mathematical physics. These days it is one of a number of choices that can be taught at the teachers...

My bad for implying that's the only possible definition. Thanks Bill
