I’ve seen similar things with a physical keyboard connected. There are plenty other Android apps that can handle connected keyboards corrected by not showing the on screen keyboard(OSK) (the now defunct RIF being one). Right now the only way to not have flashing OSK is to turn it off system wide under android settings, which is not ideal (because it won’t turn itself on automatically when the physical keyboard disconnects)
Thanks for the pointer, I actually have accessibility turned on via bitwarden (a password manager) and never thought that might be correlated. Will test when I get the chance.
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.
Mind you, the DFT calculation from the Griffin paper is not a proof of LK 99 being a superconductor in any way. What it showed is the (potential) formation of flat bands near the Fermi surface. Band dispersion is associated with the kinetic energy of the electrons, so materials with flat band (and therefore electrons with suppressed kinetic energy) at the Fermi surface are more susceptible to interaction effect (and strong interaction causes all sorts of nonintuitive quantum effects). I’m not a DFT expert in any sense, but from what I’ve heard, it is quite easy to “tune” your model to produce narrow (the limit of which being flat) bands from substitutions (e.g. the Cu substitution in this case) and such, which don’t necessarily lead to superconductivity.
So I’ll take the DFT papers (there are quite a few now) as saying, “hey you want some flat band? Here’s some. We’ve done our part. Now some other theorist, do your magic and conjure up some superconductivity”. It’s a cog in the full picture, if there is a full picture
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…
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…
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.
Why Do Cats Land on Their Feet? Physics Explains: As it turns out, felines can survive a fall from any height—at least in theory https://archive.is/j55HE
tl;dr: nothing specific to cats. It’s just an exercise of calculating “air friction” and terminal velocity. Same calculation would let a dog survive the fall no different.
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.
