! Moderator Note No, you posted it in the Lounge, but it's not appropriate for the Lounge. I moved it. ! Moderator Note That's not a consideration. This is a scientific topic, so it doesn't belong here. Please stop doing this. One thread per topic, posted in the appropriate area

! Moderator Note I concur. What's more, there isn't remotely enough rigor on which to build upon for this to be considered speculation. Timothy, if you want to learn things you are free to ask questions. But don't spam us with more of this nonsense

You got that right: it's math, not physics. So why bother with it? It's just math you made up, and has no applicability to physics. You choose the method that applies to the problem. It comes from understanding physics and the experience of having solved similar problems many, many times. You can evaluate and see what conservation laws can be applied, and what other equations can be applied. If you think you can solve a problem with mass*energy, go ahead and show that it works: derive the formula from known physics, and show that gives the correct answer. Tell us when it applies and when it doesn't, so others can test it (and make sure that whatever example you give isn't correct by accident) That's not a good enough citation. momentum is not kinetic energy. They are distinct concepts. You can check that KE is lost because you can calculate the KE for each object, and the values do not match. As in the example I gave.

I have imagined TFG et al. rooted for Cutler Beckett in the 2nd and 3rd Pirates of the Caribbean movies

! Moderator Note This doesn't really address the question of the OP, and is wandering into the territory of proselytizing, which is against the rules.

There is a shortage of teachers at the salaries being offered, under the current working conditions. Getting students to pay attention and engage is also a problem, and I would think that being online makes this harder. There have to be a number of reports on the challenges and benefits/problems of online instruction at this point.

Nah. There will still be some people, attached like remoras, who defend the actions. There are already those who are supporting the "TFG waved his hands and said 'abracadabra' so they aren't classified anymore" narrative, and some saying that a little bit of treason is OK (lots of overlap in those groups, of course) Some supporters will abandon him, as selling out his country will be the final straw. But the ones who can simultaneously believe that TFG was allowed to take the documents, and they were declassified by his incantation, the documents were returned and oh, by the way, everything was planted? Anyone who can believe such mutually exclusive things are probably sticking with him. (If TFG ever saw the movie, he probably rooted for Langella's character)

Why are you asking us? Shouldn’t you ask the person who has the details?

Kartazion has been banned for their repeated and persistent soapboxing.

That’s not what the not-paywalled bit says. Many documents are automatically de-classified on the date listed on the document (sometimes determined by some rule) but it doesn’t happen on a whim. Automatic declassification is the declassification of information based upon the occurrence of a specific date or event as determined by the original classification authority; or the expiration of a maximum time frame for the duration of classification established under the Order (25 years) … The presumption is that 25 year old information is declassified unless it clearly falls under one or more of the 9 exemption categories in section 3.3(b) of the Order and has been specifically exempted by an agency head or senior agency official. https://www.justice.gov/archives/open/declassification/declassification-faq Not being secret doesn’t mean it’s declassified.

It's not unique, though. A particular temperature profile could be generated by more than one arrangement of students. No. If you measure gravitational attraction from some distant mass, it doesn't tell you the composition of that mass. That's part of the equivalence principle.

They may have, at some point in the past, offered to pay someone on Tuesday for a nuclear cheeseburger today. Maybe $2 billion? What are the odds that TFG secretly tells his lawyers to object, and then when the DoJ says they can't release the warrant owing to the objection, he lies about it and screams coverup?

You might recall Nixon made a comeback as an "elder statesman" starting under the Reagan administration, so he was out of the White House but only out of politics for ~6 years. Copy machines exist. Who can say whether information has or hasn't already been shared?

The ice melt is accompanied by the solid earth rebounding since it's no longer being compressed by as much mass. The earth becomes less oblate, so it spins faster. But the water tends to spread out, so there is more mass near the equator, which would tend to slow it down. The current thinking is that the effect of the shape change is the larger one.

Do you mean the density of the two is equal?

Was it removed from the Archives, or never turned over in the first place? Back then there were still Republicans who respected their duty to the Constitution rather than having juts allegiance to their party. They were the ones who convinced Nixon he had to resign, because he was going to be impeached and convicted, which would be a bigger blow since it would detail all his crimes, and the coverup, and be in the public eye for longer. Trump's GOP is different. The vast majority of them either fall in line, or stay silent, when he makes his wild claims.

These things can be estimated. I once calculated that a large number of people (a million?) driving in the same direction would change the rotation rate by a tiny amount. Leaf growth would slow the rotation down in the spring and speed it up in the fall, with a larger effect in the northern hemisphere owing to the larger land area. The mountain growth has to come from mass moving from some other area; as the tectonic plates push up on the mountains, there is subduction somewhere else. I = 2/5 MR^2 for a sphere of uniform density, and since we're going for an order-of-magnitude estimate, we can use this. 2/5 * 6e24*6.4e6^2 = 10^38 kgm^2 and we know that Iw is going to be constant; the angular speed compensate for changes in the moment of inertia (I'm doing this without the morning caffeine having taken effect, so check my math) There are ~3 trillion trees in the world, and some don't shed leaves. Let's say 10^12 participate (north vs southern hemisphere) and they drop 10 kg of leaves 10m, on average. dI/dr is 2 * r dr, or ~10^8, and we have 10 kg, so our moment changes by ~10^9, meaning a part in 10^29 reduction in the rotation rate. Not measurable. The mass of mountains is much higher, but the change in elevation is smaller. Not sure what the area in question is, but keep in mind that people estimate the change in rotation rates after earthquakes, which move a lot of mass around, and these estimates are of order a few microseconds per day. https://www.jpl.nasa.gov/news/nasa-details-earthquake-effects-on-the-earth They also found the earthquake decreased the length of day by 2.68 microseconds. ... To make a comparison about the mass that was shifted as a result of the earthquake, and how it affected the Earth, Chao compares it to the great Three-Gorge reservoir of China. If filled, the gorge would hold 40 cubic kilometers (10 trillion gallons) of water. That shift of mass would increase the length of day by only 0.06 microseconds and make the Earth only very slightly more round in the middle and flat on the top. It would shift the pole position by about two centimeters (0.8 inch). Consider snowfall storing mass in higher latitudes for a few months and then melting. Droughts and floods likely have a bigger effect than the Three Gorges dam mentioned here. A bigger effect is possible if a mass is rotating, since that mass will have angular momentum. A hurricane/typhoon for example. ~200 million tons of water but rotating, some parts much faster than the earth. Any angular momentum it has has been traded with the earth's rotation.

Greg A was given more than the usual leeway, but enough is enough. Too much trolling and uncivil behavior, and absolutely no indication they were going to modify their behavior. <cue dean Wormer’s remark to Flounder> Banned.

Press release. Pretty sure some of my colleagues were tired of fielding calls on the topic https://www.cnmoc.usff.navy.mil/Portals/49/Short day press release_ngs_grc_220809_1.pdf In addition to the dip I mentioned (~1860-1900) there was an even bigger one back around 1660

So breast cancer and prostate cancer have NOTHING to with cancer. And that, somehow research into diseases is giving an ADVANTAGE to women. It does not matter a lot TO YOU. You shouldn't speak for others. I'm not sure of the relevance to your argument that rich people don't have the vice of owning yachts/multiple cars/big houses AND I said that poor people don't own them. I said nothing about the middle class. Who said anything about envy? Once again you try and change the argument, because your original argument is weak. Motivation wasn't the issue. It was who owns what, and whether rich people own stuff. You said they don't. And people "choose" not to be successful businessmen? Plenty of employed people can't afford home ownership. There's a sizable fraction of homeless who have jobs, and there are others who rent because housing costs are very high (we've been through these numbers already) Government is responsible for someone being unemployed? OK. Glad to hear you agree that Bush and Trump deserve the blame for their horrible employment stats, and Obama and Biden deserve credit for the huge improvements in them. Nobody said anybody needed two houses. That's just you, once again changing the argument. The fact is, though, that there are people with two (or more) houses. And we were talking about the rich in the US, not homeless in underdeveloped economies.

It’s funny (though not ha-ha funny) how you see being reminded of the rules, and to follow them, is viewed as a threat. If by “simple” you mean “incorrect” You’re acting like you have no agency here, when the truth is it’s a choice. You can do a little research and include support when you make a claim, as others have done in this thread, but you opt not to. You are responsible for your actions, and omission of actions. Nobody else.

! Moderator Note And the only place to discuss it is in its own thread. Advertising it in someone else’s thread is considered hijacking

Fine: prove it. Go find the data. It’s not hidden in the sunless area where most of your “information” comes from

That’s not what you were arguing, and death rate isn’t the only metric to use. Quality of life, for instance. What a convincing argument. I especially like how you backed it up with a credible source. Poor people don’t live in million-dollar homes, or own yachts. So the people who do, have these vices. Who said they did? Pretty sure they do. Poor people often don’t own homes, much less owning vacation homes.
