OK, it’s not identified as a roller coaster, and the implication is that you are starting from rest. You can use s = 1/2 at^2

Can you post the entire question, verbatim, please?

No. Temperature is a measure of the average kinetic energy of the particles in a substance. Photons are emitted by hot objects, with the spectrum depending on the temperature. You are referring to the time of last scattering. Photons existed before that time. They just didn’t travel very far before interacting.

In addition to my previous post, one should also note that auto workers took a pay cut when automakers struggled during the great recession “the UAW agreed to $11 billion in labor cuts, twenty-one thousand layoffs, a wage freeze for workers, a tiered wage system for new workers, a no-strike agreement until 2015, and the transfer of retirees’ health care and pension benefit costs from GM to the UAW, in order to save GM $3 billion. The union is still fighting to regain the ground they lost from these concessions.” https://jacobin.com/2023/09/united-auto-workers-uaw-strike-big-three-automakers-stock-buyback-shareholders

Anecdotes are not evidence. It should be expected that some auditors have police records, because a random sampling of the population will include people with police records. For your allegation to have merit, you would have to show a statistically significant deviation above the expected fraction*. If there are few auditors, as you have alleged, such a deviation could just be an artifact of a small sample size. Without knowing how many auditors there are, you can’t establish the fraction that have records. And there could be bias, because auditors might get arrested without a legitimate basis, owing to police overstepping, or due to attempts at intimidation because they don’t like being filmed. I’ve seen videos with such threats of arrest. * one-third of working-age men https://www.personnelchecks.co.uk/latest-news/criminal-record-checks-increasing#:~:text=Data from the Ministry of,someone with a criminal conviction.

The anecdotes I’ve run across for why heat waves are such an issue in Europe is the lack of AC. In the US it’s lacking the electrical capacity to run all of the AC And we fought a revolution so we don’t have to. Got rid of most of those superfluous vowels, like the u in colour or flavour.

It’s not only an issue of energy, but having a reaction mass to expel*. The longer the period of acceleration, the more mass you need, and this is inefficient because in the beginning, you’re accelerating all that mass. *unless you use photons, which is really inefficient

There have been numerous instances in the US of police summaries being in conflict with subsequently shared video evidence. In short, police will lie to cover their 6. Mandating body cameras has been one push to mitigate that, which would reduce the need for citizens to “audit” If the police are following the rules, they should not have any valid objection to being filmed. They’re supposed to be serving the public. The public has the right to film them in the US; there’s no ethical problem that I can see. Evidence?

The issue is that you are mixing two distinct effects. One is the acceleration of freefall, the other is closing speed, as Janus has explained

Evaporative coolers only work in low-humidity areas, but where they work, and water is available, sure, people should use them.

Snopes concludes it’s a fake, so if that’s correct, this is moot https://www.snopes.com/fact-check/titan-sub-transcript/ “Efficiency and brevity were a priority. There was absolutely no chitchat (such as "Enjoy the dive, gentlemen"). Often, the actual exchanges even omitted the verb, newspaper headline-style ("Bottom time up"), to save time and typing.” Scroll to the end to see all of David Pogue’s analysis (correspondent who went on a dive, and so has first-hand knowledge)

Three velocities. Two objects. The third is the result of the addition of the two objects' velocities.

I thought your point was that GNSS doesn’t rely on relativistic effects. If your point is that there are some relativistic effects that are small, that’s a very different claim. If that doesn’t change your point, you didn’t make your point very well.

The entire quote: “The main sources of relativistic effects on GNSS are relative motion between the satellite and the receiver, potential differences between the satellite and the receiver, and rotation of the Earth. The main relativistic effects on satellite navigation are [49, 51]:  time dilation  time differences because of differences of the gravity field  relativistic effects on frequency  relativistic path range effects  relativistic Earth rotation effects  relativistic effects due to the orbit eccentricity  acceleration of the satellite in the theory of relativity. There are more relativistic effects, but most of them are too small to be significant in satellite navigation” It’s clear you are quoting from a discussion of satellite navigation systems, your posturing to the contrary, but even without this, the fact that the author says “more” should tell you that there are relativistic effects that are big enough to matter. If you were referring to the motion of satellites (orbital mechanics), why are you citing a paper on GNSS?

“Overviews of treatment of relativistic effects on the GPS, GLONASS, Galileo and BeiDou satellite systems are given” GPS is a satellite navigation system. Did you not read the article you linked to? The one about relativistic effects in satellite navigation systems?

Here’s Wired’s take https://www.wired.com/story/mexico-congress-aliens-fake/

GPS most definitely depends on relativity; the clocks have to be adjusted for kinematic and gravitational time dilation to run at the same rate as the clocks on the ground.

Why 3? The velocity addition formula is for two objects. But if it works for two (and it does), it will work for three. That’s a math issue, and math works that way. And you have not provided evidence that there’s a problem.

The system you described can only exist if there is only one issue and everyone agrees on the approach. If that’s not the case, there will be representatives whose self-interest is not aligned with the voters’

I think this is untrue, as evidenced by the fact that there are people who don’t get elected, having an opposing viewpoint on some issue. The winner is aligned with a majority of voters, but not all. If there is more than one issue, you will have people whose interests align on one issue but not another. A wealthy representative’s self-interest would not align with poor constituents on some economic matters, for example.

Based on subsequent events, meaning you have the benefit of hindsight, and not acknowledging the reality of politics in general or the political views at the time. Compromises had to be made because not everyone agrees on what direction to go, or how to get there, or on what the priorities are, or acknowledging that different people have a different level of comfort with change. The 3/5 compromise was an echo of the debate on slavery in the Declaration of Independence, where a passage was stricken in order to get the southern vote. No compromise, no constitution, so any objection about slavery is moot. Yes! They included a provision to change the constitution, which was an acknowledgement that it was not a finished document.
