From a thermodynamics point of view, if you want your grades to be in better order, you will need to expend energy. ;) (best of luck)

Here's a privacy implication that should creep everyone out. I would be "good" for peering through windows - or, at least sound proof windows.

I am reading this Quanta Magazine article. And I ran into this paragraph that surprised me: If the muon sat isolated from other particles, its g-factor would be exactly 2. But quantum theory requires that all other particles influence the g-factor. As the muon wobbles, it releases particles...

Comparing a surveillance drone that is silent but visible vs. one that is invisible but noisy, I think the silent one would have the stealth advantage. If this thing was in a room with you, you would know it - and you would quickly spot it. It's hard enough making fan blades relatively quiet...

Some of those shots are not just from the drones - but from the onboard cameras that survived and are continuing to broadcast while the ship bobs in the water. The ship is mostly empty of fuel - so it is floating very high. It will be interesting to see how long it will continue floating. As...

When they develop a model with a cockpit, we'll have you check that out for us.

In an article from Northwestern University, engineers have designed a blurry drone and built a prototype. The photo below is a screenshot from the video that accompanies the article: Yes. That's it hovering in front of the plant - that ghostly torus-like thing. Per the article: To design...

Right after High School, I went to Lowell Technological Institute (LTI). Their admissions standards were moderate - but they failed more than half of every Freshman class. Let's take a look at the notion that you can use "absolute grading" to compare yesterday's college Freshmen with today's...

The Starship Flight 13 mission is expected to launch no earlier than 6:45pm (local time) today. Space Flight now coverage. If all works out, this Starship will deploy 20 V3 starlink satellites.

Anything you want. The Physics is all yours. It isn't real Physics. But you may want to make yourself (and any other occupants) similarly "unchangeable" or else the high G's on impact will leave you unpleasantly "changed".

This question is asked in the context of lack of measurable requirements makes absolute grading harder to defend. I think that @kuruman response gives you the clue to this. He creates hard measurable course objective himself and then grades to that teacher-imposed standard. He said: "In other...

There are a couple of issues here. The first is that when you ask a question about "probabilities" and leave the data collection method unspecified or up to the responder, you are leaving the question so open that even if I said "knowledge between generations is 45% and difficulty is 35%", that...

As part of your experiment, you were firing off photons or electrons one at a time. For this question, we don't really need the double slit. We can just fire off photon or electrons at a screen. If one of those particles was not fired off, it is not part of the experiment. So, within the...

You haven't made it clear whether this is college or high school. From your links, I am suspecting college - but I cannot tell for sure. I think that the first thing that needs to be said is that grades (numbers or A, B, etc) are a terse way of describing some part of the learning situation...

That's a good question - because it can tip you off to the nature of QM. If you could somehow manage to detect the fact that the screen was struck by a photon or electron, but kept the location of the strike completely unmeasured and unrecorded, then there would be no precise screen location...
