  1. I never understood how the Fukushima accident affected Germany. Are sixty foot tsunamis and M9.0 earthquakes a thing there? 9.

  2. What amazes me is that tiny dimensions were proposed by a man named "Klein".
    293
  3. That works for scientists now, too.

  4. aerospace is way more fun than physics.

  5.  @thedoctor9573  chemistry is: the physics of atoms and molecules at low energy.

  6. A meme of the 1970's SF punk band "The Tubes" would have been gold, or George Carlin deconstructing "down the tubes"...."What tubes? Where are these tubes?"

  7. that's just a descope.

  8. If dark matter is a fudge, we need to call it Dark Chocolate Matter (DCM).
    86
  9. This is depressing. The students I knew from LSND basically made a discovery that disrupts the Standard Model, knocking on a Nobel Prize, yet none of them could get decent jobs.
    74
  10. people who don't go to the ER do even better.

  11. Nice, but I would prefer a Chubbyemu collab: Physicist tried to unify gravity and quantum mechanics by adding extra dimensions: This is what happened next

  12. FYI: JPL just launched the Wide Swath Ocean Altimeter, which will map these turbulent gyres at a much smaller scale than every before. Basically, the gyres have a small parabolic shape (inches high, miles wide) that are measurable with a radar altimeter.

  13. Random thermal motion is not useless. For instance, it keeps you from freezing solid.

  14.  @ferrallc1  You mean the Nobelly^1 Prize in Economics. [1] Product does not contain real Nobel.

  16. But they were non fermi lab people off lab. So when the next LA bum assaults me, should I also call fermi lab?

  17. Why did you have to go trigger the Elon haters? Watching them congratulate themselves on their "witty" Elon roasts is no way to start a Tuesday.

  20. do any photons really travel at "c", tho? I mean at 1 Hydrogen atom per cc in space, then the index of refection minus one is ~1/2N_A (Avogadro's number) ..and that is NOT zero, so v is zero point 9 [24 times]....for a time dilation of ~ 10^24 < infinity. or a 1 ms delay of the CMB photons. Small, but not zero.
    29
  21. Sounds more like a drinking solution.
    25
  22. after years at DESY, I can say Germans do not understand Americans. For instance, we had a challenge for locals: how long does it take to build a potato gun (kartoffel-kannon?) in HH? in the states, it's 1 hour to get the parts, and the build time depends on the mix of theorist/experimentalist. It took them a day to see if it was even possible.

  26. isn;t flat spacetime stable? What makes the universe expand then? I mean that was a seriously sick surprise prediction of GR, and at a time when people were debating if it was just the milky way peppered with weird spiral nebulae, or were those spiral nebulae extragalactic distant "island universes".

  27. Future AI will probably cancel you for trying to fool its ancestor.

  33.  @XH13  what about room temp superconductors?
    14
  34. Touch grass. It got weird
    14
  35. oh, CS ppl can't do differential geometry. These are ppl who comfortable defining a "vector" as a series of floating point numbers in RAM with a fixed byte-offset. It's sinful.
    14
  36. somebody had to fill in The Chart of Nuclides, The Periodic Table, and whatever O-chem has....most science research is a grind that doesn't make the news. Regarding your last statement--I saw a talk on mesophysics, where stuff is too big to be a single "thing", and too small for a thermodynamic description to be meaningful. During Q&A, Steve Koonin called a uranium atom "macroscopic".
    12
  37. the way y'all get triggered by Elon is so cringe.
    12
  38. but is she left-handed?

  40.  @TheEulerID  it's not chemistry until it forms a molecule.
    12
  41. actually, you saved me. I was offended by 1 > 2, but since the whole thing is mod 2, it really said 1 > 0, and I can now fall asleep to Sabine videos and still respect myself in the morning, again.

  43. In LA, a third world alpha city, I can get fiber installed within 3 days...in which time I can schedule and get a CAT-scan and an MRI.
    11
  44. And the defense demands it be judged by a jury of its peers.
    11
  45. Idk, In the us if you’re on a jury, the judge can prohibit you from reading blogs during the trial. Worse, if the case hinges on QM interpretation, and the defense brings in a many worlds expert for testimony, you can’t go with your hidden variables interpretation and must go with the testimony. Ofc, the defense would have thrown you out during selection.
    11
  46. But the authority figures get to decide what is evidence, or did you miss that?
    10
  47. they're a doublet...unified above the GUT scale.
    10
  48. well they are massless, so the minimum energy is 0, which means "pocket sized" or smaller. Note that LIGO watched a mirror move 1/1000-th the diameter of a proton, and about 10^30 gravitons passed through each antenna.
    10
  49.  @adamgroszkiewicz814  perhaps he was thinking on the micro, like what the birds sing, or which worm to have for dinner?
    10
  50. There are no reference frames at c. Also: a photon is a quantum of field excitation. It has no inherent energy nor wavelength. Those properties depend on the motion of an observer…..who can make it anything they want from greater than zero to less than infinity

  51. why you guys hating on Elon so much?

  52.  @bitskit3476  it’s the active ingredient in bud lite

  53. The only reason to think antimatter would exhibit antigravity is that they both have "anti" in their name. We would have been spared this concern had it been called "conjugate matter". edit: still, it's a good experiment

  54. Or I was told to post this by my supe at you tube. They was to by the fbi what to post, cause democracy and stuff

  57. magnetic fields don't penetrate superconductors 😞
    8
  58. quick English note (as someone who lived in DE, this is a classic mistake): "143 nm is just about in the UV" means it is NOT in the UV, but really close...like UV starts at 120 nm or something. I believe you meant: "143 is barley in the UV". I know, they sound identical, but they are not. E.g, in a race "You barely won" means you won by a smidge, "you just about won" means a silver medal.

  69. How do you get tenure at a good university when the FFC is decades out (publish, ofc, but publish what?)? And when it is built, it will need 10,000+ student and post docs...how many 2 year post docs can you do in a row, bouncing around academia? Do you check any hiring boxes? Is your PhD going to be searching through "used" data for a bump--with ML, ofc, so your advisor can get tenure? js/
    7
  70. So I read that the 1st LIGO detection (which was a ridiculously tiny measurement), involved a GW with a graviton occupation number on the order of 1e30. So we're not seeing gravitons anytime soon.

  76. I don't believe in burning books, but if I did, that would be the 1st one. He's a crackpot that can do math. But seriously: you will gain no insight into the wonders of physics reading him, nor watching his yt channel.
    7
  77. one way to do that is look at the mirror nucleus, which would be carbon-10. The nuclear force is symmetric under p, n -> n, p interchange, with any difference resulting from electric effects (and chiral symmetry breaking.,..but there's alway a caveat in any nuclear physics statement)
    6
  78. QCD has 8 gauge bosons. They all point indifferent directions in an 8 dimensional space that doesn't matter, but it's still is 8. (Unlike the weak force, where there are 3 abstract directions that do matter, and other complications).

  79.  @Thomas-gk42 north is the top. Look at a map.

  80. It starts in a pure state: |resin>|hardener>, and then goes to a mixed state: |r><r| + |h><h|, makes perfect sense.

  81. room temperature superconductors have left the chat.

  82. Well axions are an old theory, and weren’t introduced to solve dark matter. So this is a cheap experiment that may have have a huge payoff….very much like a lottery ticket.

  94. It’s the coefficient, or weight, of the position eigenstate |x> in the state |psi> = sum over all X of psi(X)|x>? Maybe. All I know for sure is that Born was Olivia Newton John’s grandfather.

  96. omg, this is so true with "what is an atomic orbital".

  97. but the climate catastrophe needs more than CO2, it needs all kinds of positive feedback loops to go from pleasant warming to certain existential threat.
    5
  98.  @aupotter2584  no. The standard model is QCD, 3 color charges for quarks or 3 anti color anti quarks and 8 color/anti color gluons binding them together, with the experimental fact that all observed states are colorless….leaving 3 quark baryons (and anti versions), and also q qbar mesons. The strong force is then the residual force between baryons and mesons, with the mesons acting as force carriers that bind baryons. In regular nuclear physics the baryons are just neutrons and protons (see: hypernuclei for more), and a plethora of meson “currents”. Nuclear structure is so far removed from QCD, it’s hard to link them….maybe in the EMC effect or Color Transparency….but idk what the status of those are. It would be like learning about maxwells eqs from the vanderwalls force….too many complications.

  109. 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.

  110. 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.

  120.  @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.

  123. 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.
    4
  124. 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.
    4
  125. That didn’t happen, tho.

  126. 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.
    4
  127.  @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.

  136. 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?

  143. 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.

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

  145. 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.

  148. does the effect get saturated? I mean 1850 GPa is a lot, I think. Pascal is an SI failed unit.
    3
  149. 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.
    3
  150. 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.

  153. 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.

  156. 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.

  160. 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.

  186.  @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.
    3
  187. 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.

  247.  @TheLivirus  the synchrotron I saw was from 28 GeV positrons going around Hamburg. But on second thought… it may have been a black and white camera. Since the visible spectrum is so far below the critical frequency for any reasonable source …power would go like the cube root of frequency….which is pretty mild, so white is reasonable. Cherenkov has number of photons proportion to frequency, power as the square of frequency, and it is most certainly blue (and UV)…. But I have on,y done Cherenkov and bremstrahlung professionally…and the latter was in the few GeV range, far from visible. Regarding the color..idk my atomic and molecular lines, but it comes from solar wind ionizing or exciting atmospheric gases, and then in recombination or deexcitation, characteristic lines are emitted (scintillation) but note: it depends strongly on pressure and temp, because the mean collision time can be much less than the excited atom/molecule lifetime, and collisions quench the emission. Oh, and I worked in gas scintillation, since it is background noise for gas Cherenkov detectors. So I worked in everything but synchrotron. Except for the fact that DESY used synchrotron emission to polarize the positron beam via the Sokolov Ternov effect.

  278.  @ManuelGarcia-ww7gj  the experiments I reference are called deep inelastic scattering…where the electorn or positron (or muon…eg leptons) beam interacts with individual constituent or sea quarks. Lepton number and quark number is conserved, so there’s no path to annihilation with photon exchange. However, an e+ and a down quark can exchange a W boson which turns them into an electron neutrino and an up quark, respectively. But: the rate it which this occurs is tiny (weak force is weak), and the detectors aren’t able to detect it. Nevertheless, the inverse reaction is observed in neutrino deep inelastic scattering…but I’m not to familiar with it….though the combination of the two methods is how we confirmed the quark content of protons and neutrons.

  322.  @GeoffryGifari  no, way too complicated. And it ps repulsive in the d, not everywhere. Basically it’s Paulo exclusion principle, the lack of pp and nn means it’s not np + pn, so it must be pn - np, which changes sign on interchange. That means the spin state needs to symmetric, and that’s spin 1…so the over all wave function changes sign when particles are interchanged.

  329. that depends on your definition of new physics. A change to relativity would certainly be new physics. Some unknown WIMP would be a new particle following old physics, which is often called new physics, but it's really "new stuff in the old physics"...unless it's interacting field didn't transform as a representation of the Lorentz group, which brings us back too modifying relativity.

  331. Changing gravity is symmetry breaking gone too far (for my tastes, but my taste could be unphysical...I laughed at the higgs mechanism once). I've also liked some kind of right handed weak interaction analog, making WIMPS, otherwise...why would the weak interaction be left-handed? Idk, maybe that's been ruled out.' Nevertheless, most of our existence requires the weak interaction to break all kinds of symmetries....with out it: all quarks would be stable, and all leptons...now try to imagine what that would do to the periodic table of elements, and "Isotopes" would be called "SU-6-topes"...a real mess.

  334. Exactly. So weird that it makes no sense. It's a spin-0 nuclear after all. After some thinking and looking at Clebsch-Gordan tables, I'm guessing , the 2 alphas are in an L=2 state (D-wave), and so are the neutrons l=2. With |Mm> referring to the alpha, neutron z-projection, the CG tables says: (|2, -2> - |1, -1> + |0, 0> - |-1, 1> + |-2, 2>) / sqrt(5) is spin zero. ...ofc that violates the Pauli-exclusion principle since neutrons are fermions, while alphas are bosons....no, never mind....the neutron spins are antisymmetric.

  337. btw, napkin calculations go like this: 1) energy ~ radius/beam ...so this are fixed. Let's say 7000 Gev. 2) Lorentz factor ~ energy/mass = 7000/0.105 ~ 70,000 = gamma 3) lab lifetime = gamma * tau = 70K x 2.2 us = 1/7 second = T 3b) compare to LHC, which I think is around 10 hours? ..idk HERA was much longer. 4) Total energy in LHC beam: 350 MJ = E 5) Power required to just replace muon decays: E/T = 2.5 GW...which powers 1000 cities? idk, kw-hours/month is a stupid unit...I might have goofed. Synchrotron losses go as 1/m^4 (iirc), so muons lose about 6000x protons (while electrons: ~ 10 Trillion x). so lepton storage rings topped out w/ LEP.

  339. I've gone though many understandings of HUP. The math way (operator algebra) is the simplest, but least illuminating. Finally I decided on "what is momentum?". For a wave function it's the derivative of the wave function (and mostly the phase part, which is ignored on many YT presentations). Of course, the position is the wave function (squared) itself. Can you draw a function that has an exact position (a delta function) and also has a constant derivative over all space (exp(ikx))? No, you can't. So why is momentum the derivative? Emily Noether, that's why: the derivative generates translations, and translation symmetry is what conserves momentum. When you come at from a classical view, mass times velocity, which is how we all started, that connection is lost.

  370.  @mikemondano3624  one of the bigs....I think Poincare? We had newtons laws, thermodynamic, EM, and in Lagrangian, Hamilton, and Hamilton-Jacobian formalisms. Given the correct initial conditions: all could be predicted. At this point, they didn't understand chaos , which is still classical, so infinite precision can transform it from chaos to basic dynamics. The addition of relativity didn't change that. Of course, if you think classically, it's very difficult to come up with a microscopic theory of matter. Without the Pauli exclusion principle, it really should collapse. And then ofc, full blown quantum mechanics is totally different. And QFT--yikes, and all that led to the Standard Model , which is awesome, but leaves some questions. When particle physics entered cosmology and computers allow us to model galaxy-clusters (or bigger or smaller sized) systems...here we are.

  380.  @Thomas-gk42  that depends on the results of double beta decay experiments.

Imagine a world where there are no flavor changing weak currents. We would not exist. The periodic table would be hell.

While Swiss Francs per TeV is nice (11:20), I suggest a purer unit, we could even call it a Hossenfelder, and we use gold to connect physics to finance: 1 Ho = (1 Mole of Gold atoms) / (MW-hr) A mole of gold is trading at 10,885 Swiss Francs.... now we can make this unit dimensionless by multiplying by [Yes, that guy aging: c^2], so nuclear at $80 / MW-hr is a nice and neat: nuclear power --> 4/3 Ho.

  469. It's true nothing is fluctuating. Eigenstate like the vacuum are called "stationary" for a reason. Nevertheless, to get from the vacuum now to the vacuum later, you need to take all possible paths....that conserve energy an momentum...so there is no energy popping in and out of existence per Heisenberg, that description is a left-over from old fashion perturbation theory and was sent to the waste bin of history by Feynman, Schwinger, & Tomonaga a long time ago.

  473.  @henriksundt7148  well I remember reading in the LA Times (so a while ago), when the EPA declared CO2 to be a "pollutant", and that was that. Zero push back. It was now a fact. In contrast: when HHS (or USDA?) declared ketchup to be a "fruit & vegetable" for the school kids--there was opposition. Both are instances of "Unelected agency declares [common substance] to be [something], with major ramifications to: people" Obviously a limnic eruption (just regular years ago--Lake Nyos, 1986) is a different situation.

Peace Prizes accordingly. 2) OK, Ante-Cold-Bellum: What is the biggest threat to world peace? The remaining super power. Who dat? USA. What's their problem? Capitalist, white, christian, nationalist, colonialist, imperialist, etc, etc. (sound like a lecture at the Kennedy School of Government). What the best way to end that threat? Elect a non-white (non-chrsitian (no-capitalist (foreign born (....etc)))), with the 1st one being the most important. So it's not what he did (nothing), it's what he represented: a destabilization of the identity of the greatest threat to world peace: boom, peace prize.

Connecting 2:46 (diffraction through a slit), and 7:00 (interference)...Nick Lucid said the wave going through the slit doesn't behave any differently than the unblocked portion of that wave; rather, the wave that cancels the spread downrange (which is always there) is blocked by the barrier, leaving the now uncanceled part of the initial plane wave...spreading out.

  501. btw: E=hf does not define the energy of a photon...a photon doesn't have an inherent energy, because it doesn't have a frequency nor a wavelength. Those are properties that exist only on the reference frame in which it is considered. Any single photon can have any energy the open interval (0, infinity)...the limit is how fast can you imagine your inertial frame is moving, and I can imagine any speed on (-c, c) [also, open].

  503. A normal graviton is just a quantum of non-flat spacetime metric, so it's not some missing particle, it's gravity at a scale we can't probe experimentally. When you have a lot of real gravitons (like 10^30 of them), well, LIGO sees those. Any massless spin-2 particle gives the Einstein field eqs. Torsion in the metric of spacetime is not new. I've seen it, but never studied it. GR is a field theory, where the field is the spacetime metric--if you quantize that, I mean what is an operator valued metric?...you get infinities. So there's not much new here, unless it's renormalizable (I guess it is?), and it makes testable differences from GR, and if it doesn't: can we at-least calculate things in the highly non-linear region, i.e: what's the singularity in a black hole?--or is it like QCD, a beautiful theory for some, but to quote Fredrick Zacharison, "an ugly disgusting mess that makes me want to vomit" when you try to calculate the simplest bound states (e.g., a proton).

Multiverse, eternal inflation (even though I like it), mirror antimatter universes-idk, it just seems to makes noobs think physics is full-of**it.

  513. @ tensors are geometric objects that are eigenstates of rotations, which gets complicated (racah algebra) fast. And a scalar is NOT a number! It’s a geometric object that rotates trivially. Shame on Sabine for implying otherwise.
    1
  514.  @edwardmacnab354  exactly, it's just a number, and a number is not a scalar. Scalars rotate under the trivial representation of SO(3), while numbers don't rotate at all. But there is an argument to promote it to a scalar, as it's sometimes related to the trace for a tensor (dyad): Tr[<(v - <v>)(v - <v>)>] where you subtract the mean <v> to make it Galilean invariant (don't start on relativistic temperature).

  637. Ok, I am offended. As a recovering nuclear physicist, A nuclear transition is a gamma ray, I don't care if it's keV. Inner shell atomic transitions are X-rays. Ofc there is some overlap, but we can deal with that.

  638. In each case, the only constant is a "infinitesimal probability of decaying in the next infinitesimal time period", leading to exponential decay of a large sample. That decay has a time constant tau (it the 1/e life, as opposed to the more human 1/2 life). What that means is the energy of the excite state (or parent nucleus) has an uncertainty ~ h/tau. For a 4By 1/2 life U-238 nucleus, that is pretty tiny. The mass is well known. For a Delta Baryon (tau ~ 5 x 10^(-24) seconds), the mass uncertainty is ~ 100 MeV, or about 1/8th the average mass. See "Breit-Wigner distribution". For atomic transitions, see: "natural line width". without these energy uncertainties, you'd never excite a state, because the photon would never have the exactly correct energy to infinity digits.

  640. the graviton is irrelevant. It's not a particle, it's a quantized gravity wave. We know gravity waves exists (one set moved a silicon mirror <100 zm in 2015), and that wave would have 10 Mmol of gravitons, if GW are quantized)...so we won't be observing them, ever. There's still the problem of electro-nuclear unification.

  643. no, but I just did. How does that get published? 1) a proton is a ground state of |uud>, so the title is sus.  Spin flip excitations are called "Delta baryons", and lesser known orbital excitations fall under N*(nnnn) where 'nnnn' is the mass in MeV/c^2. See: The PDB (pdg dot gov). Then they bring in general relativity? I don't get that at all. The pop sci view of a proton with sea quarks and gluons popping in and out of existence is misleading. Protons are static--all free protons are identical at all times, though they are loaded with gluons and q-qbar pairs. (they might be modified in nuclei, though--EMC effect is still a thing). They also might evolve in scattering (Color Transparency). Also: they are spherical. any other shape violates parity and time reversal (see: Neutron EDM). They do have a direction (spin/magnetic moment)...but that's not a vector direction.

  651. This is too complicated. The top layer of the atmosphere is going to be at a temp that has sigma * T^4 over 4pi matching the solar constant over 2pi-R. That is the temp at 1 optical depth, the questions is: how many optical depths from the surface to the emission layer? More optical depths means a hotter surface.

  652. 8:44 not the gradient of the magnetic field, but the electric field….which accelerates linearly. Magnetic fields are for circular machines, and we don’t use electrons because the energy lost to synchrotron radiation is huge vs. protons. But, protons are bags of garbage so you don’t really know what you’re colliding….while electron/positrons are pure.

  653.  @Mentaculus42  1) if you can do electromagentics, that is good. Many a spy satellite actively uses some part of the EM spectrum, and I tell you, these engineers just don't understand it deeply 1b) there's also the passive blackbody domain. 2) In simulation, engineers are terrible at uncertainties, e.g you sim the 99.7% success in your Mars landing and ask them : what the uncertainty on that? Boom: blank stares. 3) Hypersonic reentry? does quantum degeneracy (identical particles) mean the Apollo reentry code doesn't work on Mars? Yes. Do aerospace engineer understand that? No. How many mars rovers go long before they figure it out? 4) Star tracking: does special relativity matter? Yes it does, do AE understand it? No. Same for GPS. 5) does knowledge differential geometry make a better interfermometric synthetic aperture radar processor, in FORTRAN, yes it does. 6) GN&C: flight software loves quaternion, hates "direction cosine" matrices. Do AE understand representation theory of Lie group (and hence: quanternions) No. They do not. 7) plasmas and ionosphere stuff: forget about it. Saha equation is a mystery to them. 8) Kramers-Kronig relation--does it come up in AE? Yes. Do AE's understand it? No...same for Fokker-Planck fluctuation dissipation theorem and other forms of noise. They just see colors (white, brown, pink, blue)....we see: physics. 9) they can't do anything "coordinate-free", everything needs a reference frame and "components"--yuck. It inhibits understanding. So that's just off the top of my head. I am sure there's more reasons why a giant DoD prime or FFRDC would want someone who knows physics on staff.

  671. By time-of-flight? (A tried and true method in particle detection). Since you don't know which slit it went through, the distance it traveled is uncertain. Even in single slit diffraction, the lateral momentum spread is inverse to the slit width (and you don't know where it went through the slit). It always works out.
    1
  672.  @mobatyoutube  basically. For the diffraction slit it's just trigonometry. Lasers get more complicated (say in the delayed quantum eraser) because the photon doesn't start when it comes out of the laser, it's been bouncing around that cavity for some time (leading to the coherence length), and can really be anywhere within that length....which is why the erasure seems to happen after detection).

  780. no, it's not forgotten. Assuming that talking about an idea is the same as supporting it is a standard tool, possibly with some twists, used to silence debate. It's basically a cloaked ad hominem. It is used daily, and applied liberally when needed. Here's a hypothetical (with a twist, since we go from ideas to basic word association): A comedian tells a joke about a neglected US territory's landfill problem that has been growing since it was hit by a hurricane 4 years ago; the comedic twist occurs when were led to believe the subject matter is major environmental problem that has the word "island" in it (oh, and the Territory is also an island). The crowd, being not to bright, boos the joke due to the negative word association. Nevertheless, the entire incident is used as an ad hominem "proving" the subject believes unacceptable things about the citizens of the US Territory. It's easy to do, and it works on dumb people, emotional people, and reasoned smart people with deep biases.

Classically there is a field, e.g. from a bar magnet...it definitely makes a force, but when you get down to the quantum level, there is a minimum excitation of the field, which we call a particle. Then when you want to do a calculation, you can't solve for the field configuration so you approximate it with 1 or more "virtual" particles.

  818.  @GeoffryGifari  Both my copies of Halzen and Martin we stolen years ago. Wikipedia has a nice page on using virtual particles in the static limit to recover 1/r^2, with Yukawa being modified w/ exp(-r/m). Basically it's a math technique, where you start w the 19th C Green's function, which gets Fourier transformed into Feynman's propagator (FT of a delta function is 1/q^2...or something like that). S my point was, that it is too technical for noobs, and just leads to confusion--but you're not a noob. The concept is very useful in Deep Inelastic Scattering, and the "Rosenbluth Separation", where the kinematics has a free parameter to dial the virtual photon's longitudinal polarization and then extract electric and magnetic responses as a function of length scales...also Hofsteler (not Leonard ;-)) won a Nobel for related work. For gravitons, I saw a Kip lecture where the LIGO detection (measuring a 1e-18m wiggle !) was a wave with 1e30 gravitons..so we won't see them until we can see the Planck Length, hence I don't worry too much about them.

  845.  @GeoffryGifari  (1) is my favorite question, and no AI has ever got it right. In the chiral limit, p and n are two states of the same particle. P is isospin up, and n is isospin down, and the nuclear force depends on the dot product of isospin…which is called an isoscalar force….the math is the same as the math of spin or magnetic moments in zero field….and the chiral symmetry breaking is like turning on a weak field that slightly differentiates the two states…e.g the neutron is slight more massive than the proton. But not much. Anyway, there are 4 n p combos that are isospin states, which, like quantum spin of two,electrons are divided up into: Isospin 1, symmetric under particle interchange pp nn (pn + np) / sqrt 2 And isospin 0, antisymetric under interchange: (pn - np) / sqrt 2 So the isospin force is repulsive, and the anti symmetric one has a 0 factor, leaving other attractive forces working, hence the deuteron is isospin 0. The isospin 1 wave functions are not bound. So here the AI question: There is no helium-2 isotope, nor an di-neutron: what is the spin of the deuteron? Btw: try to answer it. It’s simple, but don’t feel bad, many PhDs have failed. Not nuclear physics PhDs, but others.
    1
  846.  @GeoffryGifari  on (2), electromagnetism is 137 times weaker than the strong force, and the you need to square that to get and energy difference. So less than one part in ten thousand. It only starts to matter in large nuclei, which pick up a factor of Z squared, and the nucleus is bigger than the range of the strong force. T and He3 are mirror nuclei, so have the exact same structure….in the chiral limit. But chiral symmetry breaking…which just means down quarks are heavier than up quarks, makes neutrons heavier than protons….that means the density of final states is go for the decay, the decay happens. HE3 is heavily studied because it can be polarized, so it’s a stand in for a stable polarized neutron target. See proton Spin crisis and the Bjorken Sum rule….both of which are backed by brutal theory….way harder than high energy particle physics…(it’s called medium energy physics, and doesn’t get as much press. Btw, I’ve been out of it for 25 years, so my info may be dated. I do 🛰️ stuff now…more job opportunities).

  847. a graviton is a quantized amount of curvature in the metric. It's not really a big deal. Since the LIGO detection that moved a mirror 1/1000 of a proton size had about 1000000000000000000000000000000 gravitons in it, they won't be detected individually.

  864. Fun Fact, on weaker gravity at higher altitude: the gradient of the gravitational field is captured in the tidal tensor, which is diag(-1/2, -1/2, 1), so the fact that a fiducial volume of air above weighs less (because g is smaller), is EXACTLY, canceled by the fact that the volume is larger because the line-of-force diverge as you go up (1/2 in 2 transverse directions cancels -1 in the longitudinal direction), so the total weight of the fiducial volume is the same. This is because div(g)=0 in space.

And we're not talking about refraction, which is a relation between two angles, easily derivable from continuity of the wave vector across the boundary--but that's not relevant to the speed discussion. regarding interactions: what kind of interaction? ppl are saying the light scatters. How does that work? If it's scattering, why doesn't it scatter? Are we talking forward scattering?
    1
  869.  @VonJay  I need to pay attention to your words? for real? There's no angle. The incidence is normal, and the light enters the medium and slows down. Are you assuming a changing E field induces a B field (and vice versa), and that leads to the propagation of light?

  872.  @rodschmidt8952  and it's traveling slower than light. Now on this thread I've been told I'm "ignorant" for not knowing the opposite of what you said it true (that non-linear QED effects, which should occur above the Schwinger Limit are observable at all magnetic field strengths, which would mean a photon doesn't need to be in a medium to have a finite n-1.) Personally, I've worked with both real and virtual photons (both near shell and deeply-virtual..polarized, even) in the GeV range, optical/IR quantum light, and classical EM from hundreds of MHz to sub-THz, and photons from atomic/molecular scintillation, Cherenkov radiation and its weird cousin: Transition Radiation,...and interferometry (both amplitude and intensity, the latter with pions, tho)..oh and with the photon's hadronic content as in VMD/diffractive rho & phi production/pomerons..oh snap, and with parity violating photon/Z-boson interference coupling to the strange sea, so I think I have a decent understanding.

  873.  @a64738  well Fermat's principle says it takes the longest path (in time), but if you change increasing time to (fixed) frequency times increasing phase, the extremal path has stationary phase so amplitudes add coherently for that path...this works classically (e.g, Fresnel Zone in telecom) and quantum (Feynman path integral). regarding index of refraction, idk if it works in space, one retort that the atom spacing is>> wavelength was a legit complaint--it's not measurable anyway...but ppl talk about light traveling at c in material, and the phase shift makes it look slower. It's true, but saying light travels slower is fine too. Now if you toss Maxwell's eq and use Jeffimenko's (equivalent) version: there is no light propagation, there is just causality propagation where light is only caused by charges and currents on the past light cone, not by changing fields from the prior cycle. rn I prefer Jeffimenkos's Eq, even though I can't stand "c is the speed of causality" posts...but all views have their regions of application, so it's best to know all of them (which I do b/c I've been doing it for 45 years...shit I'm a decade older than Sabine...I musta twin paradoxed, cause I look good).

Didn't tailgate me after that. the other problem in LA is that any police activity could lead to a pedestrian running across your lane....and that's easier to deal with at 50mph than the standard 85.

  944. A good look at this problem is when is it rn on Earth (x=0 Mly)?, easy, it's t_e=2025 AD. So E_0 = (2025, 0) Ok, so when is it right now at Andromeda (x= +2.5 Mly)? easy, it's t_a = 2025 AD. So E_1 = (2025, 2.5M) Now the paradox. When is it on Earth, right now at Andromeda? That is, at event E_1, now, 2,500,000 ly away, what's the simultaneous date on Earth? Since Andromeda is closing at 300 km/sec (0.1%c) = 1 ly/kY, you get: t'_e = 2500 AD + (2500 kly)(1 ly/kly) / [1 ly/ly]^2 = 4525 AD. Yikes, so right now in andromeda, it is the year 4525 AD now.

  963. so lets do an analogy with positronium, radius goes as 1/alpha x reduced Compton wavelength -> coupling constant / electron mass. Now we look at bound nu/nu-bar: mass is a factor of 4e-6. idk about the weak coupling, but if I go by parity violation in atoms, squared, that's a factor of 1e22...so a bound neutrino should have a radius on the order....no, I am not going to square it, 1e11 /4e-6 = 2e16..times a0 -> 1200 km, with a binding energy that is micro. now put that quadrupole mass moment in a gravitation field: I think it's falling apart.

Wtf? Any this scientists the has all kinds of stupid advice on what to do because the president listens to him and holds a press conference every day and when we get a new president the scientist says he felt he could finally speak freely which makes no sense because he was given a mic and a national stage every day for months then he lies to congress, which can be a crime depending on who you are, about how he made the monster that everyone was scared of but the worst part is when ppl who you thought were smart deified this guy and you’re all wtf?

  980.  @bacca71  don't capacitors automatically lose 1/2 their energy?
    1
  981.  @bacca71  the 1/2 is fundamental and taught in basic physics. From hyper physics: The problem of the "energy stored on a capacitor" is a classic one because it has some counterintuitive elements. To be sure, the battery puts out energy QVb in the process of charging the capacitor to equilibrium at battery voltage Vb. But half of that energy is dissipated in heat in the resistance of the charging pathway, and only QVb/2 is finally stored on the capacitor at equilibrium. The counter-intuitive part starts when you say "That's too much loss to tolerate. I'm just going to lower the resistance of the charging pathway so I will get more energy on the capacitor." This doesn't work, because the energy loss rate in the resistance I2R increases dramatically, even though you do charge the capacitor more rapidly. It's not at all intuitive in this exponential charging process that you will still lose half the energy into heat, so this classic problem becomes an excellent example of the value of calculus and the integral as an engineering tool.
