  1.  @JonS  because you need to be in grad school to appreciate why his equation is such a banger. And his lectures on QM, where decides the Poisson Bracket is a commutator with some imaginary non-zero value are...pretty abstract.

  2. It’s not just schools, the burden at FFRDCs (e.g., aerospace corporation, JPL) is similar, if not more.

  3. You learn the bomb is live because it blocks the photon's path without blocking the photon. The photon takes all possible (2) paths from source to "B". If both paths are open, those amplitudes cancel and the photon has a probability of 0 of reaching B. If the live bomb blocks the path, there is no cancelation and a photon can reach B, but if the live bomb blocks the photon it explodes. Hence: if the photon reaches B, it means the live bomb blocked it without actually blocking it. idk, it's hard to describe in words.

  4. I think it "predicts" general relativity in the hbar -> 0 limit.

  6. actually, kinda. But the boundary is made up of complex numbers, and then at a point in the interior you pick a wavelength and add them as if they were waves with that wavelength propagating to that point, ....and then you FFT over all frequencies. maybe. something like that.

  10. The intro is bit misleading, in that it described the fusion as if it where in a plasma, but with orbitals filled. For a normal deuterium gas, D2, you have the nuclei in an orbital with some overlap at r=0. Normal D2 gas will fuse this way, at a really, really slow rate. With a muon serving in the role of an electron, the nuclei are 186 times closer, so the overlap of the wave function goes way up. The point, tho, is that temperature doesn't matter: we're not smashing D's into D's via internal kinetic energy, rather just letting quantum mechanics do its thing on a molecular orbital.

  35. they really don't. I didn't realize how bad it was until I lived there. One thing that I find fascinating about both Europe and the Commonwealth countries (where I also lived), is that they think they have free speech, and when you press them: they don't want free speech, and don't even know it.

  36.  @tubebrocoli  In the regular YDSE, one can put a delay on one of the slits, this changes that beams phase by pi, causing the former peak (trough) positions to shift to trough (peak) positions. In the DCQE, the blue (yellow) beam takes two (one) bounces to reach D3, and one (two) bounce to reach D4. The relative difference in number of bounces affects the peak position on the screen via entanglement. delayed-choicethe coherencelengththe cavityThisfrequencyshould detected It seems acausal, but the whole Heisenberg Uncertain principle leads to relativity violations, which is how we got stuck with quantum field theory.

  37. That’s what I thought….the peak was in X ray diffraction. Basically the FT of the crystal structure. But I wouldn’t call this stuff inelastic, which implies a single scattering event (at least to me). It’s just energy loss in media, which implies inelastic in the name.

  38. my (undergrad) standard model TA, a theorist, said 1 = pi = 2 = sqrt(2) = I = -1 (this was in case he had to evaluate a diagram) and no, it wasn't Terrence Howard.

  39. First they came for the flat earthers, and I said nothing because I wasn’t a flat earthed. No, really, if you didn’t see the assault on flerfs as a beta test of both software and user compliance, you were not paying attention.

  40.  @purplerpenguin  dark energy doesn’t lack confirmation, it has one and only one observable effect, and that effect has been observed. In my opinion, dark matter exists, too: since 1933, our galaxy 🌌 isn’t revolving around nothing. That it hasn’t been observed in particle scattering is problematic, but that’s part of being “dark”. 🤷‍♀️

  41.  @BorisEysbroek  that limit needs a name....a pun. I immediately went to Eddington-Finkelstein, and thought like the Epstein-[someone] limit, but EF are coordinates, and the Eddington limit is the limit. But Epstein by itself doesn't work.... How many named limits can you name in 30 seconds? I think I have 5.

  43. define "promising".

  44.  @aaronjennings8385  That's funny. Does AI know that "promising" figuratively means "it will likely deliver", but it's literally correct also for "lying con-job", as in both cases, promises are made.

  45. And the atoms don’t matter. You can swap them out for other like minded atoms…classically. Quantum wise, swapping out atoms is at most an unobservable change of phase.
