Like.
No, you couldn't, because any such effects would just end up being entangled with everything else, and in any given branch, there would... -
gentzen reacted to PeterDonis's post in the thread Undergrad "The wavefunction never collapses" with Like.
No, you end up in all branches. You do not end up in just one. So there can't be any "hidden variable" that "determines" that you end up...

I would recommend you to actually read the original EPR paper! It is eminently readable! In EPR they define a necessary (not...

I don't even know what this means. In the sense that the measurement interaction is what entangles the particles with the measuring...

gentzen reacted to DaveE's post in the thread High School Reducing loss of energy for Lasers with Like.
Alta used either 257nm or 244nm from a large frame ion laser, I don't recall. Diodes have a tough time with the shorter wavelengths...

gentzen replied to the thread High School Reducing loss of energy for Lasers.I always associate the MEBES e-beam mask writers (and the corresponding file format) with Etec. But they also had the ALTA advanced...

gentzen replied to the thread High School Reducing loss of energy for Lasers.No, high end masks are written by e-beam lithography, either by VSB (variable shaped beam) machines, or by electron multi-beam (grey...

gentzen replied to the thread Graduate How valid is the indivisible interpretation of quantum mechanics?.The discussion did not just "feel" more substantive. What I have watched so far (~1h 43min) was factually a lot more substantive than...

gentzen replied to the thread Undergrad Particles' Intrinsic Properties in QFT.What is your point? I already agreed with Roberto Pavani that one can interpret the word "intrinsic" (including connotations) in a way...

gentzen replied to the thread Undergrad Particles' Intrinsic Properties in QFT.As I said, I don't see why "frame-covariant properties" should be considered to depend on "a particular choice of frame". I already...

gentzen reacted to Matterwave's post in the thread Undergrad Particles' Intrinsic Properties in QFT with Like.
Expanding a little. States in QFT live in a Hilbert space. The irreducible subspaces of that Hilbert space has certain symmetries...
-
gentzen replied to the thread Undergrad Particles' Intrinsic Properties in QFT.I see. But then it mostly boils down to how one wants to interpret the word "intrinsic" (including connotations) and how one wants to...
-
gentzen replied to the thread Undergrad Particles' Intrinsic Properties in QFT.So you mean, only a scalar property can be intrinsic to the particle? I don't see anything wrong with a Lorentz covariant vector like...

gentzen reacted to FactChecker's post in the thread A question about quantum entanglement with Like.
IMO, you are putting words into my mouth. I reasonably thought that we were discussing the SR theory of what is happening now, locally...

You can certainly debate anything, but SR is generally formulated on the constancy of the speed of light and the equal validity of all...
