Looks legit to me. Thing gonna change alot

What are the implications in general of room temperature superconductors? I just know that they needed typically ultra low temperatures right? But what would be the practical implications?

Anything that uses electricity would use less electricity because you aren’t wasting it as heat.

So in theory you could have a ridiculous computer that runs 1000GW of power through it without heating up. Or a flying car. Or power cables that lose nothing during travel.

Naturally that’s why it doesn’t make sense. It’s too game-breaking to be possible in normal conditions.

Glitching something out by making it basically maximum cold makes sense because you’re making it fully still so that it stops messing with the current. Glitching something out by squeezing it until it can’t move makes sense. Leaving it in a normal room means it would have to be something completely crazy.

"In no case may a prize amount be divided between more than three persons." [1]

Sad state of affairs to expect a reward for brilliance and to have science bottlenecked by a merchant of death. Just the fact that the merchant of death gives "peace prizes" should have made the entire affair laughable a long time ago. Perhaps it's time to move on from this ancient and limited understanding of appraisal, awards.

I'm in no position to ever receive a Nobel prize, but I'm fairly certain I am moral enough to reject such a grandstanding award coming from such a troubled tradition. Yes, I just virtue-signalled calling immoral every recipient of the Nobel Prize, mostly out of sheer distaste for the ceremony, but also thinking of the terrible inefficiency which has plagued science and research in the last 122 years. How many discoveries were missed because following the course to unveil them was not "Nobel-worthy". How many scientists had their careers ruined for pursuing the Nobel award without being granted anything. Just the fact that only 1.8% of the Nobel Prize in Physics were awarded to women [2] shows the entire thing as the charade it is, no other context needed.

If this is true, I'm really curious why SK didn't bury them. Samsung foundries have been also rans for years, this seems like completely game changing technology. If it's real...

Automatic subtitled translation is "furiously" laughable. :)

Ooh, please share pre-prints if and when anyone sees one for this group

Hoverboards.

Is this actually true? It is not obvious to someone somewhat versed in physics how this is enabled by room temperature super conductors unless the entire riding surface is magnetized.

It does require a magnetized riding surface. Lexus made one!

Yes, it is obviously not very accurate (sample is not in a rage :)) but I'm sure many are excited about the possibilities and don't know Chinese (Mandarin?).
