  1. You do not have an adequate understanding of relativity to contribute here.
  2. How does assembly theory deal with/explain the Miller-Urey experiment?
  3. Go ahead. But as I had said, this assumes there is no substance being presented, i.e. the label is all there is.
  4. Not a fan of this style. It's lazy, for starters, to tag things with a label. Almost like you don't have an argument and have to rely on the flash of name-calling. It also implies that it's fashion, like someone is going along with the crowd, and not that the position is sincerely held. "Particularly and sadly on a science forum." Oh, the irony. How about substantive discussion instead of name-calling?
  5. What equation(s) have you learned that would apply to simple harmonic motion, that depend on amplitude, position and period? (people aren't going to do the work for you)
  6. Moving clocks actually run slow. Read what else Janus wrote. One effect in play is "Time dilation, which always has the moving source clock tick slow" Kinematic time dilation has been experimentally confirmed many times. To deny that it happens is ludicrous. If you synchronize two clocks and move one, and then bring it back to the source, it will indicate less time has elapsed. In such a demonstration the clocks would be co-located and at rest when the comparisons are made, so there is no doppler shift to cause confusion. Time dilation is a very real effect. It's important to define what you mean by perceive. One needs to distinguish between the raw data (what do my eyes see) and the underlying physics (what do I measure), as I mentioned earlier and the explanation I linked to. The doppler shift will make the two not be the same; the changing travel time of the light has an effect. A measurement requires that you remove this confounding effect. Once the effect of that travel time is factored out, during the trip C will conclude that A and B are running slow. A and B will see C's clock as running slow. When C reaches the destination and stops, next to B, C's clock will have run slow (C has undergone an acceleration, which allows one to distinguish between the effects; they are not symmetrical) Yes. If you are collecting pulses of light as your measurement, it's why the raw data disagree coming from A and B during the trip. But you can't make a conclusion about what the clocks are actually doing of you are excluding data that is in transit. You have to collect all the data to make a valid measurement. If you wait until all the pulses arrive, the time on A and B will agree, as they must.
  7. CUD, SCUT, DUCT, BUST
  8. Source? I see summaries, but the only purported links I can find are in Russian, so I have to wonder where this originated. Also, opinion is just opinion. Aiding in defense is not aggression.
  9. An important point. They must still be entangled for the explanation I gave to hold. The measurement has to happen after the second electron reaches its destination. Holding the electron has to happen in such a way that you aren’t collapsing the wave function (i.e. breaking the entanglement)
  10. It’s not a guess. In the train’s frame of reference, moving clocks (e.g. the tower clock) run slow, because time runs slow. The tower clock ticks normally in the frame of the tower. There is no valid absolute statement you can make about time and ticking (e.g. “The clock ticks as normal” or “Einstein’s clock is actually ticking slower” ) since all measurements are relative. This is well-established physics. There is no illusion here. If you want to peddle an alternative idea, do it in speculations. Moving clocks tick slower, but you have to distinguish between measurement and observation, because light has a finite travel time. Janus has made multiple posts that explain this better than I can one example https://www.scienceforums.net/topic/120625-are-relativistic-effects-directional/?tab=comments#comment-1123814
  11. The military's 2021 report said no evidence of aliens had been found. Scott W. Bray, the deputy director of Naval intelligence, told lawmakers that they still haven't uncovered anything "nonterrestrial in origin," even though there are incidents they can't explain. Why do people keep mentioning aliens when the reports say that there is no evidence of aliens?
  12. “nobody does it” is a pretty lame excuse. Passing the buck. Not giving your income to people outside you group is also an applles-to-oranges situation, so it ends up just being a distraction; an irrelevant argument. Nobody has a huge bonfire with the cash they earn as celebration, either. Who cares? It has nothing to do with the situation In the US equal pay for equal work is the law, which is why they were able to sue and force a settlement. Can you prove they couldn’t have gotten more? You haven’t backed any of your arguments up yet. This is just so much bloviating So what? We were discussing US soccer, not other countries.
  13. I had that happen with a paper in a journal, with a technical editor, who should have known better.
  14. Why bring it up as a discussion point if nobody does it? If things were different, they’d be different. I was citing the facts of the matter, which includes their fight to get equal pay, which is what they sued and negotiated for. You said you’d be in the middle no matter what gender you chose, which isn’t the case when one gender makes 20% more than the other. The middle of the curve for one is not the middle for the other.
  15. Because left to themselves, schools were biased. Legislation was necessary in order to promote equal access, using the lever of eligibility for federal funding. That continues.
  16. Does anyone do this? What the players make and what the national team makes are separate issues, and the disconnect was a reason behind the lawsuit and negotiation for equal pay. U.S. women’s soccer games have generated more revenue than U.S. men’s games over the past three years https://www.cnbc.com/2019/06/19/us-womens-soccer-games-now-generate-more-revenue-than-mens.html There’s no gender wage gap in G7 countries? https://data.oecd.org/earnwage/gender-wage-gap.htm
  17. What is <i|j> when i ≠ j ? (They are orthogonal; yes, it’s because you’ve got a diagonal matrix so you have eigenvalues and eigenvectors)
  18. Scientists play around with ideas that don’t necessarily work out, but reveal things nonetheless - excluding lines of thought, advancing ideas that might apply elsewhere. There’s a lot of “what if” that happens. There’s no inherent problem with “just asking questions” on either side of the aisle.
  19. Because of the Kronecker delta in the first highlighted equation https://en.wikipedia.org/wiki/Kronecker_delta Which is there because <i|j> is in the preceding equation. Do you see why that is?
  20. One could Google this.
  21. No, it was not proposed to be an illusion. The clock ticked slower because time slowed down, owing to relative motion. Sure. It isn’t brought up because it’s irrelevant to the thought problem.
  22. That’s probably a regulatory classification because one deals with the public. But having to evacuate is an indication that something went wrong, and not according to plan, because if it did, you wouldn’t have core damage and a release of contaminants I imagine the SL-1 incident didn’t require much in the way of evacuation because it was remotely located, but it’s hard to argue it operated the way a reactor is supposed to. It, too, exposed design flaws. But this also shows that there have been more reactor problems than the three that hit the news from 1979 onward.
  23. Right, but you don’t have to do it that way. If you went to the lab next door, your field could be at any arbitrary angle to the other measurement. Up and down are relative to however you set up the quantization axis where you do the measurement. If the spin was aligned with the N pole in your lab on earth, measuring along that axis - however it is aligned with regard to anything else - will give you your down spin in the lab at M87.
  24. Up and down are dictated by the local magnetic field You have to transport the electron in such away that you don’t collapse the wave function, but beyond that it doesn’t matter. The spin is undetermined, and what matters is the field when you do the measurement.
