Is this accurate? Are non-supervisory police on salary, or are they wage employees, who make a lot of their money on overtime (time and a half)? Not sure it’s fair to say we “expect” them to work long hours. Also, on the list of dangerous jobs, there are only a couple that pay much more than policeman (on average). Most pay significantly less https://www.monster.com/career-advice/article/high-paying-dangerous-jobs

I think the US police problem is also linked to our incarceration problem, another difference between the US and Europe. (which may be in that video, which I can't watch ATM)

That's the whole point of "defund the police" - they are not trained for many of the jobs they are being asked to do, and money would be better spent on people trained to do those jobs. And we run into problems when people trained in the use of guns are asked to do jobs where guns are way down on the list of solutions to the problem. (When all you have is a hammer, and all that). You use the money to hire people trained for these other tasks. That way, fewer police are needed. Your bit about specialization points to this. I was reading recently how this has already happened. Once upon a time police were summoned for medical emergencies, and transported people to the hospital. But police are not trained to deal with medical emergencies. When we replaced police and police cars with EMTs and ambulances, we got a better result. https://twitter.com/JamieFord/status/1272273637173637120 "Defund the police" is applying that same rationale to other aspects of what is now police work. Don't send untrained people with guns into situations where guns won't help, and might make it worse. Send people trained in that particular situation. (BTW, I do more than 5 hours of training per year as a federal employee. If police aren't doing more than 5 hours then that's a broken system)

You don’t have to stop counting until you bring them back together. No timing required, though that’s not a big issue (if you do a measurement that lasts a day, who cares if you have a few nanoseconds of dilation. It has a negligible effect on the answer, if you do the experiment properly). You start and stop with the two systems next to each other. Yes, this has been done with clocks. Tom van Baak’s version was to bring some clocks up on Mt Rainier for few days while the family went camping, and compare to the clocks left at home. http://www.diyphysics.com/2012/03/15/tom-van-baaks-family-friendly-relativistic-time-dilation-experiment/ (I think someone linked to this recently, but I don’t recall which thread)

How does the rate of radioactive decay depend on Planck’s constant? Why not address the experiment I described, instead of trying to come up with a more complicated experiment?

We’ve done the equivalent experiment with clocks, several times.

That’s not how clocks work. That’s not even how these measurements work - we don’t care about this “rectangular pulse” We just count the decays. Discrete values. We have a radioactive sample. We measure 1000 dps at the reference system. Now we move the clock up such that the frequency changes, according to your theory, to 998 dps. GR predicts 1001 dps. Let the system sit there for an hour. Then we compare to the reference. From what you’ve said, your prediction is 120 decays fewer, what GR predicts is 60 more.

I’m talking about an atomic clock. What are you talking about? What relevance do those drawings have? If I have a clock running at a frequency F, and I count the number of “ticks”, I measure time. Now we take a clock, running at F, to some new height, H, above the reference clock. According to your earlier post, the frequency will be lower by a relative value 2gH/c^2. I can count the number of ticks at this new height, return it to the original height and compare it to a reference clock. GR predicts a higher frequency at H, and you predict a lower one. This is easily checked and trivially falsified.

How about addressing the clock experiment I have brought up twice.

So this implies that you think these other terms are constant, but hbar and c are variable. Why is this? Why aren’t you saying charge is variable, too? Why not? The effect is on rates, so one clock evolving at a faster rate will accumulate more phase. (i.e. time) This can be directly compared to a reference clock.

A shift in the frequency emitted by a photon means the transition in question has shifted by that amount, and you're saying the shift is in the opposite direction predicted by GR (you say the lower system has a higher frequency). Is that correct? 2 problems with this: 1. If the frequency shift is predicted to be two times as large, then what happens if you just don't send a signal, so there is no photon. You move a clock to a certain height and let it accumulate a difference in time, and then move it back to the reference point, and check. No photon to worry about, and there's a factor of 2 difference in the predicted effect. Easy to observe. (Yes, the experiment has been done.) Therefore, easy to disprove the conjecture. 2. I don't think this having asymmetric shifts is consistent with the Pound-Rebka effect. You have the photon shift of one value, but the resonance of the atom has shifted by a different value.

That's what you're trying to show, so it does not "follow" in that what joigus stated is part of standard electrodynamics. The speed of light can vary for other reasons, such as from the change in index when it's in a medium. It also deviates from the invariant value if you are in an accelerated frame of reference. OK, so what's the prediction about the net effect on time? How is gravitational redshift an "illusion"? Why do we get good agreement with the GR formula if there is this other effect of opposite sign?

As joigus said, you have given the definition of the fine structure constant. You haven’t presented any connection between GR and QM. Did they measure this? Did they do it in free space? The key here is “irrefutable proof” Science doesn’t deal in proof, and is never irrefutable. They will never pay out, since they have a way out of doing so.

You can’t summarize?

The devil’s in the details. How do you do this? Why are existing experiments insufficient to confirm relativity? Where does Yanchilin's formula come from? Why is it necessarily correct if GR is correct? How do you arrive at that interpretation? They measured the magnetic field near a black hole binary, not the permeability of free space.

No. Why would you think so? What are the mental gymnastics involved in such a question? Oh, FFS. It’s hardly an argument, when it contains intellectual dishonesty

Where did this red herring come from? We’re not talking about all criminal activity, we’re talking about police, who are supposed to protect and serve the public, and who should be held to a higher standard. We’re also talking about violent behavior. That’s not an instance of excessive force. I was short of straw before but now I have a lifetime supply. Sure. But you had only proposed screening for white supremacy Yes. If they had not tolerated such behavior, you might say...

Which wouldn’t have stopped George Floyd’s death, apparently. Zero tolerance for excessive force behavior, regardless of motivation, might have.

When one says “casts doubt”x it’s usually to deflect a claim. Does the motivation for police killing an unarmed, handcuffed, black man matter? Or are we only trying to stop white supremacist cops from taking black lives?

Was it alleged that he was? Does that make a difference?
