You do realize that “speculation” as used on SFN means you have some kind of evidence. It’s not a WAG, and the plural of anecdote is not evidence. What you have is a narrative, and are cherry-picking information to support it. Your story, for example, suggests that the children were not supervised, which is a funding issue, if you don’t have the staff to do this. It’s not an inherent discipline problem. And how, pray tell, does having an online teacher solve the issue of students running off?

If they are tilted along an axis of latitude, which is what is typical, this is still the case. (I’m ignoring any effect from being raised off the ground, which has minimal impact)

“in my area teachers make a decent wage” is something you asserted as fact. (BTW, I was able to easily find that where I went to school the 2019 entry salary was about $46k, median is ~$70k and salaries top out at ~$100k. This ranks them in the upper third in the state. They report new union contracts in the local paper) I agree that salary is only one component of hiring and retaining teachers, but an important one. Teaching online doesn’t solve the issue of being underpaid. What is your evidence that the lack of “methods to control the classroom” is the missing component? I don’t recall this being an issue when & where I was in school. What is different?

! Moderator Note The material here doesn’t meet our requirements for speculations. Too vague and broad. We need some actual way to test the idea - a model, specific predictions. Arguing against Popper isn’t an acceptable substitute, and should be a separate discussion.

I disagree. There is no interference pattern because it’s just one electron. But there is interference, and the electron will hit the screen only in a spot that corresponds to an interference maximum. That the electron might not land along its classical trajectory (i.e. not the m=0 location) is IMO remarkable. And yes, this experiment has been done, in showing that the interference pattern shows up after repeated single electrons passing through the double slit.

"he doesn't say how he knows" And neither did you.

Or just someone who is informed. What is that "decent wage"? On average across the United States, a high school teacher working in a public school earns $65,930 a year. The average occupation in the U.S. that requires at least a college degree pays $92,175 a year – according to government labor force data for May 2019. https://www.usatoday.com/story/money/2020/09/29/states-with-the-most-underpaid-teachers/42699495/ (as you note, teaching often requires other courses beyond just a college degree)

Let's say a person on a planet in space is in frame O, and a rocketship is carrying a passenger in frame O' The rocketship (O') is traveling at speed v with respect to O They want to look at an event that's taking place (an explosion on an asteroid) at point x and time t in the O frame. They would use the Lorentz transform to find the location (x', t') in the O' frame. Notice that the details of the motion of the asteroid (it's moving at speed w with respect to O) doesn't matter. We know it's at point x at time t

It's more of an authoritarian/narcissistic thing, perhaps popularized recently in the US. I'm sure if other dictator/dictator wannabes (or their disciples) get voted out of office outside the US, some of them would try the same tactic. You are glossing over the controversy. One needs to look at the details more carefully. The Soviets "won" on the third try at the last three seconds, which never should have happened. Lots of shenanigans involved to get to that point. https://en.wikipedia.org/wiki/1972_Olympic_Men's_Basketball_Final#Controversy

If the body is at rest in O', then it is moving at v with respect to O But since the transform is essentially looking at a snapshot, the speed of the object doesn't matter if we are just transforming a single point described by (x,t) in O and finding its coordinates in O' Or you can get the transform the function x(t) and get x'(t') (this would have the object's velocity information in it)

Depends also on your reference year Real GDP or Gross Domestic Product (GDP) at constant (2011-12) prices … First Revised Estimate of GDP for 2019-20 of ₹ 145.69 lakh crore. https://statisticstimes.com/economy/country/india-gdp.php Matches up pretty well.

Or you can use the country’s own currency, the rupee

The x and t are the coordinates in the O frame, and v is the relative speed of the two frames. x and t can have any value; they are unrelated to v. edit: xpost with MigL

Energy is released only if a stronger bond is formed. If all you’re doing is breaking a bond, it requires an input of energy.

My own favorite is laser cooling and trapping, which uses photons (the electromagnetic interaction) to manipulate atoms and molecules. Related are various kinds of electrostatic and magnetic traps for ions and neutral atoms, respectively.

! 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?
