  2. That reminds me of the Chris Rock routine we’re here sick of dads getting extra props for staying with their family. “So what, that’s what you’re supposed to do”.

  8. I saw the zodiacal light once, from Death Valley...and then Vandenberg launched a rocket right in front of it and that was that.

  9. As a repatriated ex-pat: America has a phenomenal train system. It just moves freight, because Americans make stuff, and if we need to get some where, we do it at 550 knots. Europeans put people on trains so they can take 6 weeks of vacation from their 35 hour work weeks.

  10. Well, they would make an exotic atom, with the p bound to the alpha-bar (or are we doing atoms?), and since the overlap is large the p would pick off a p-bar, or an n-bar... modeling the strong force a pion (+,0,-) exchange...they don't care about anti--since their anti is (-,0,+)...which is the same thing. That would release a lot of energy. Whether it would unbind the spectating anti-T or -3He sounds like a long messy painful traditional nuclear physics calculation...the kind that makes particle physicists run for higher energy.

  13. You programmed index of refraction. Tunnel requires that the kinetic energy in the barrier is negative.

  18. regarding plant pronouns, should we refer to 420 as "she/her"? I mean think that is a thing.

  20.  @randallbsmith  Yes. Yukawa posited a ~100 MeV particle (based on range, hbar time c = 200 MeV x fermi) and then the muon was discovered. Eureka! ....then not Eureka. But the pion saved the day, and that it had +, 0. - versions was quite nice for symmetry reasons.

  22. a self-organized-critically video would be nice, or one on power-laws, or phase-transitions/renormalization/ long range order from short-range interaction....

  23. Search term: The Glauber State. A coherent plane wave, the ones we use in undergrad EM problems, is not an eigenstate of the number operator, which is quantum-sprecht (QS) for: there is no fixed number of photons, usually. They must be using a “Fock State”, such as |1>, which is QS for one photon. 🤷 quantum optics is hard.

  24. Ok, I looked it up. It replaces the neutron with a bound proton and electron. we already have a bound p/e pair: the hydrogen atom, and the Bohr radius is the Compton wavelength of the electron divided by the fine structure constant for a reason. So you can't confine and electron to the volume of a proton w/o making positrons/electron pairs. Moreover, no neutron would break many observed isospin facts, and the would then break quark flavors. Also neutron stars and white dwarfs would be screwed up. but the most important thing is that there is absolutely no need for it.

  25. That didn’t happen, tho.

  26. Yes! But the Coulomb central force is exactly solvable super degenerate (read: easy), and spin and relativistic effects are tiny perturbations. In nuclei, you have a non-coulomb central force (it's a mix of repulsion and attraction). the spin-spin and spin-orbit terms are of the same size, and there's a non-central (tensor) force, and individual spin-orbit and helicity terms. Back to atoms, you can treat the electron orbits as independent...each one just see a central force electric charge, in nuclei, each nucleon sees all the nearby nucleons...so it's a many body problem. for charge particles, only charge matters, but in nucleons there's a strong force, and then there's another one that cares if you're a proton or neutron, in a way that is independent of being a proton or neutron---and protons and neutrons lose their identity in a nucleus....the colored ball picture is wrong...they're all in entangled states of being part proton, part neutron. No matter how big an atom is, it's a sum of 2-body interactions. The strong force has 3 and even 4 body interactions that cannot be broken down further---it's just a huge mess. Finally: quantum field theory effect (the Lamb shift) are tiny corrections to atomic orbitals. In the effective field theory of the strong interactions, the nucleus is full of virtual pions, sigmas, even kaons... so as messy as you can imagine, it is far worse...while an atom is basically Laguerre and Legendre polynomials.

  27.  @DocKobryn  quantum number are easy, the exact wave function are not. After some thought….and my PhD was 30 years ago, and useless, it looks like the alphas orbit it each other in a D wave (L=2) and the neutrons do the same, and they combine with equal weight with m = -2, …., +2 and +2, …, -2 which gives a spin zero nucleus. So while they are in a relative dumbell shape, the over thing is perfectly spherically.

  28. don't degrade yourself. It's a slippery slope. Next thing you'll be OK with a Peace Prize, living in a VAN DOWN BY THE RIVER

  29. that's BS. JPL nails it every time. Wannbe's don't. And MPL is on Dan Golden's "better, faster, cheaper" ...which was stupid from the jump.

  30.  @ivanminevski714  part of the problem is that The Founding Fathers didn't know how massive the federal government would be. It really was "united" "states".

  36. basically all conserved quantum numbers are opposite, baryon/lepton number charge, colors, (idk about the weak sector, there's probably a twist)--so the anti quarks are anti-red and so on (which is cyan, idk...I like the faux color model). Anyway, a neutron is a charged object with a charge distribution and a magnetic moment. Does anyone complain that anti-hydrogen (made at CERN) is neutral?

  37. and our models don't care about our coordinates. Kinda of a big deal, really.

  43. Moving objects don't shrink. People looking at moving objects see them as they are: smaller, but only because they measure the object's ends different times. The object itself not only hasn't shrunk, it's not even moving, it puts it all on the moving observer's messed up coordinates. Motion is relative.

  44. LIGO is space is LISA, and I think SIM for a while. Idk, it's been around since the 90's.

  45. Also: A scientist should not be using the political term "Climate Deniers"...esp. not a German, but that's a hole nutha thing. A more accurate term would be "climate catastrophe denier". Ofc, "climate catastrophe" is unscientific, and it is now appearing in formerly reputable publications like Scientific American. Furthermore: climate scientist who advocate policy to non-policymakers are being unscientific, they are engaging in politics, and we know that corrupts. A scientist job is say "we're gonna die if we do X". Here's what happens when we do "Y +/- dY" or "Z +/- dZ". Elected officials then choose X, Y, Z, ..., and the People choose the elected officials. Once the scientist skips the middle and tells the ppl who to choose--s/he's lost objectivity, and it is a scientific fact s/he will be biased. So it's antiscience to deny your own bias. They become bias-denier.

  46.  @Biga101011  I know former funders at senior NSF levels--s/he was a pro: pay attention to climate change when Obama was president, drop it like it's got when he left...b/c like NASA, NSF is executive branch.

  47.  @wheressteve  you have a point. Permitted stairs have limited rise/run metrics, and escalators violate those at the ends for sure.

  48. does the effect get saturated? I mean 1850 GPa is a lot, I think. Pascal is an SI failed unit.

  49. because a state can be messier than the most certain state. In telecom/radar there is a minimum time (duration of signaL) * bandwidth product >= 1 (same Fourier math as here), but people like to put information in their signals, and the product is called the signal's "sophistication", e.g. a "chirp", "phase-coding" and so on. Also: triangle inequality.

  50. draw the quark diagram: (-p; +n) -->( -u -u -d; +d +d, +u)....now annihilate a u pair and a d pair: -u +d, which is a pi-. now the weak interaction changes flavors so (changing notation): pi- = u-bar + d -> W -> mu minus + (neutrino) -> positron + (neutrinos).... why it doesn't;t decay into a positron 1st is a whole left handed "thing". and no, it's not a stupid question.
