Well the band wagon has turned 180, now it’s fashionable to point out the flaws. My issue with this kind of videos is really, where are you in the early days of the hype, when the public needed cautions the most? A convenient naysayer when all the actual hard works have been done elsewhere

OK, but where are they when the LK99 first came onto scene?

Documentation is different from demonstration. Text (with graph or animation interspersed to unpack unintuitive terms) wins for documentation. Video could be good for demo if presented in a no-nonsense manner.

Now let’s see which youtube “science channels” do a debunk on their own content pushed out a mere month ago.

The point is there are established conventions among the practitioners on how these are pronounced, and not getting them right says something about the youtuber who may otherwise appear as an expert.

You might be right on how the name ‘Schrieffer’ should be pronounced in its original tongue, but I’ve heard multiple former students and colleagues of Bob Schrieffer pronounce it otherwise to conclude that theirs is probably how Schrieffer himself intended his name to be pronounced.

Yeah, can’t wait to hear economists’ take, or The Economist’s…

Hi Joe Brian

It is waiting for reproducibility is what it is. It won’t matter much if it got published today in some no name journal – a journal is going to gamble just as this youtuber did, for the slim chance of this being true (not saying it isn’t)

Also, a quantum well is just particle in a box. Nothing fancy about it. Guy mentioned tunneling a lot but tunneling happens in metal, semiconductor, and insulator. Doesn’t really mean anything. In fact if you need to tunnel, that means there’s a chance to back scatter, so it won’t be superconducting.

Not to be snobbish or anything, but at this juncture I wouldn’t trust anyone who can’t pronounce arXiv (or Schrieffer for that matter) correctly to explain room temperature superconductivity to me. Hell I barely believe anyone with a materials/physics degree…

In general you’ll be happier if less fxxk is given to someone else’s opinion. I’m not sure how important “someone else” being a parent is, other then maybe the correlation with the time spent with them or the survival resources they had control over, etc.

In fact this goes all the way back to Hamilton when he invented quaternion, in which i,j,k are used as basis vectors (which are generalizations of the imaginary i). Later Gibbs dropped the scalar component and gave us the modern vector.

The “state” in “most likely state” refers to a macro state, which in the “packets of energy” example is specified by the pair (left total energy, right total energy). A macro state with more microscopic realizations (hence more likely – all microstates of the same energy being equally likely) has higher entropy by definition. The video could perhaps make the distinction between micro- and macro-states more clear, but doesn’t seem like a misconception
