I have a PhD in material science and worked with superconductors, here are two things that is often misunderstood: 1) it takes a undergrad to make and measure a superconductor but a Nobel laureate to explain it. 2) in theory if you understand the mechanism of something you can improve it. In material science however almost always all you need is a trial and error approach to end up with a good result. Conclusion: the…

It's a feedback loop. Experimental results suggest new theories, which suggest new experiments to test those theories.

Because if true it will be the most important discovery of this century?

The most important discovery of the century will probably be whatever finally lets us make human level AI.

That may be the last science Nobel awarded to a human

Einstein did experimented a lot too, even if it’s generally not as highlighted as his thought experiments.

This first sentence is vague. Are you saying things must be made before they can be explained, as the sentence reads?

Or is there a typo and this should be “and a Nobel laureate to explain it”?

I don't know much physics, but is there a reason we should be hoping for superconductivity specifically rather than a cheap material that's just a very very good conductor? Also, even if LK-99 were superconductive, that wouldn't imply it would be useful for computing, right? Surely there are materials that are better conductors than silicon but have mechanical and other physical quirks preventing us from using then for chips.

"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…

"This makes me way more excited this discovery miiight be for real." I agree it is a strong indicator, that there might be more to it, when there is already fighting about the rewards. It is a shame though, if it really works, there should be enough fame (and money) for everyone involved. I mean, a worldwide lossles energy grid, high speed trains, fusion plants and floating cars do sound nice .. assuming the material…

It's only a superconductor at milliamps, so we'll need another material for your high energy examples. The biggest deal would be providing a trajectory to materials science.

If it would be reliable working at milliamps, I am sure it can be put to practical use in my sci fi scenarios eventually (1000 cables with 1 milliamps each should add up to 1 amp?). Of course, unless it all just is a quirky side effect, that can never be put to practical use.

Time to invest in lead futures?

Or buy car batteries while they're still affordable.

Lead is less abundant in the Earth's crust than cobalt or neodymium, or even lanthanum.

There is a lot more than just silicon wafers in our computers. Let's start with all those traces on board. Right now they are made of copper. But what if they could conduct with 0 resistance?
