"The Meissner effect (or Meißner–Ochsenfeld effect) is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state when it is cooled below the critical temperature. This expulsion will repel a nearby magnet. " - from wikipedia. I had to look it up.
I’m not even smart enough to understand this headline
Superconductor. It’s baa-aaack!
I never did have to pay out the 100:1 odds (or whatever I was offering) to anyone from day 1 of the previous announcement…
I have no more faith in this one, so I’ll go 100 to 1 odds again, that this will not result in room temperature super conductors. Anyone want to take me up on this?
If it turns out I’m wrong I promise I’m good for it (if room temperature super conductivity is a thing I’ll happily give away all of my life’s savings, as money will quickly become meaningless), who wants to give me their money?
I’ll bet you one upvote, and I’ll pay it right now!
If you’re confident why not throw out 1M:1? I’ll take that bet with you. 100:1 sounds like you’re not that confident.
Because I hold out hope it’ll happen some day.
And within a decade of that day, if it comes from easily fabricated materials, money will mean nothing, and I don’t care to fight with the crazies who will try to be hoarding it. A few thousand, or hundreds of thousands, would probably be easy to acquire, millions feels like too much work, even if it is worthless. I’m thinking about my future (dream) spare time (also a dream), and I don’t want to commit future me to coming up with those amounts. I’m sure future me will have a few hundred for anyone if anyone ever took me up on my offer.
So my offer stands at 100:1, because I’m serious about paying out on it when it happens, when else do you get genuine offers at those odds? Give me your dollars.
And how is this different than LK-99, which was pretty conclusively proven to not be superconductive?
Lots of geaphs instead of a photo of a hovering piece of metal. And they are more careful with wording, ‘possible Meissner effect’ is less headline-catching than ‘wow we discovered a superconductor’
Yeah, the last one was sensationalized to the point it felt like dishonesty (and, quite possibly, was). But when something like this comes up, it’s still important to put it out there. The more eyes on it, the better.
It has already replicated, with two separate labs in China confirming the results. When LK-99 was announced, it was still awaiting replication. The chemical difference appears to be that this thing has sulphur where LK-99 did not.
A potential “room-temperature” semiconductor?
Not another one :p
Oh no, a potential revolution in technology, again. How tedious.
copper substituted lead apatite is literally what lk-99 was. Obviously the exact number and process could be different but colour me extremely skeptical after how that played out.
Call me when it gets past being a headline in some tech journal.

There are many room-temperature semiconductors, for example silicon.
Meissner effect is related to superconductors
Pretty much all my semiconductors operate well above room temperature! (relatively)
