The jiggle is bizarre. If it's not Meissner, that's a hoax. If it's Meissner, the effect is strongly biased towards one end and the repulsion is very strong. It also rotates with the magnet. If it's a hoax- at this point, wtf. Would be the end of all scientific reputibility in SK for life.

Okay someone help my dumb butt understand this

I had a toy with a bird that could hover on it's beak with a magnet. How the motherfrick does something reacting to a magnetic field prove they've created worlds greatest superconductor that will change the world?

Like I'm pretty sure my grandma who gave it to me bought it in Puerto Rico. There's no way that dumb poor country created a superconductor that will change the world as we know it and sold it as a tourist trap toy

It doesn't.

There are basically 2 ways stuff that isn't a magnet can react to a magnet. Most stuff is attracted towards it, but there is also stuff that is repelled by magnetic fields. Superconductors are super duper repelled by magnetic fields. So when you put one in a field it doesn't like to move around.

Nerds call that repelling property diamagnetism. And just because you can make a piece of rock that is kind of diamagnetic doesn't mean it's a superconductor.

  • Regular magnets can't do true levitation, it's just repulsion but with something physically stopping the floating bit from flying off

  • Diamagnets can levitate, but will freely rotate separate from the magnet

  • Superconductors are locked in place and will stay at the same position relative to the magnet, unless you poke it or whatever

:marseysal: but this does kinda look like #3.

Also, was your toy the balancing bird? Because that has nothing to do with magnets, grandma lied to you.

I guess lead/copper wouldn't normally react to a magnet, but since they did their superconductory thing to it, its now magnetic because of super conduction?

Lead and copper :marseybongcop: both react :marseywebshit: to magnets. They just do it with so much loss that it looks more like a temporary flutter than true levitation.

What r the implications if any 4 quantum computing

The discovery of a new mechanism for making other ambient pressure superconductors is much more important than this particular material.

What r the implications of ambient pressure sc in general on quantum?

I'm worried 4 my crypto bags if we're about to get quantum cracked

Yes, a room temperature SC could make large scale quantum computing possible which would easily nullify the public/private key cryptography of all banks, payment processors and blockchain nonsense

not permanently, rsa and ecc will die but cryptography will survive, even asymmetric. And symmetric crypto is mostly unaffected.

Ok got ya, that makes sense but I guess a video like this still doesn't prove it's made out of something that wouldn't react to a magnetic field
