It didn’t pin, it bounces, if it was flux pinning it would not bounce when you push it down.

Yeah, it's jumping back to a fixed position which isn't how I thought the Meissner effect worked. Since this seems to be posted by someone reputable though it's weird they missed that.

Flux pinning is distinct from the Meissner effect

Forgive me, I know little about these things, but what’s the relationship between this phenomenon and the quantum locking seen in other super conducting magnets, this looks as described as “pinned”, what would allow it to behave like the famous video of the magnets levitating around that circular track: https://youtu.be/Ws6AAhTw7RA

Superconductors will resist moving at any direction where the magnetic flux gets weaker, stronger, or changes direction. That's why they get described as "pinned".

Other diamagnets do that too, but in a decaying way that allows for movement. They usually rotate or move slowly sideways.

No other kind of magnetism show similar behavior. They either attract or repel all the way in.

Is this material safe to handle? It feels like this thing soon will start appearing all over ebay and aliexpress

Would that be legal, considering they have a patent (pending) for it? Not denying it won't appear anyway just curious

It is illegal in places that have rule of law.

This is to create a risk reduction mechanism for investing in capital to make this at scale, which will cost on the order of $100-500M to scale for world use through trial and error.

If IP is ignored, no business will invest in the initial experiments due to first mover disadvantage in game theory.

Earlier quoted context omitted.

A very large quantity of discoveries in science are a combination of "well, that's odd" and the "sheer luck" associated with the circumstances producing that statement. (This isn't a commentary on the truthfulness of the superconductor claims.)

Yes, but that doesn't answer the question ...

Yes it does, the answer is both, but with the caveat that there were people focused on rolling the dice of luck to search for this.

What I like most about this development is that, suddenly, folks with "CEO " or "Founder " in their Twitter bio look uncool, while folks with " " in their twitter bio are uber cool. Note to pedants: yes yes, the Venn diagram has an intersection.

People with in their bio have always been cooler

Not if you belive that

Folks with CEO or "Founder" in their bio have always looked uncool imo.
