Superconductors . --superconductors . Again, in the '80s, we were led to believe that around the corner, we would have desktop room-temperature superconductors .
superconductors so they're the people who still are interested in it you are
In a superconductor , they're massive.
And Paul Chu discovered the high temperature superconductor YBCO.
They die off the surface of the superconductor .
that could power future technologies from superconductors to batteries.
And indeed, in a superconductor , photons are massive.
So what if we live in a cosmic superconductor ?
--any development that's on the path to room-temperature superconductors .
And I have studied a wide range of materials from superconductors , to ferroelectrics, from borides, to oxides.
But that means the magnetic field lines basically get repelled by the superconductor .
So if you have a quantum theory-- if you develop quantum mechanics in that superconductor -- you'll describe electromagnetism as a short-range force.
Sciences the universe is much simpler than a frog or than a high temperature superconductor it's the same everywhere the same number of galaxies of different
- Astronomy with superconductors on the top of a mountain in the middle of the world's oldest and darkest and driest desert.
And then on top of it, you apply a superconductor .
Well, nowadays, we have high-temperature superconductors so we can do need experiments in high school physics classes, because we can put a superconductor now
And, for example, if you have a superconductor in dry ice, and you put a magnet above it, the magnet will levitate.
Because it turns out magnetic fields cannot pierce the superconductor .
Well, for you, if you live in that superconductor , electromagnetism is a short-range force, because electric fields and magnetic fields, when they enter the superconductor , die off--
It means we live inside of a cosmic superconductor .
This is just a material you may have heard of high temperature superconductor .
a list of a few that I put down last night, room temperatures superconductors .
So these sensors transduce the microwave heat into electrical resistance, and then we're able to measure that on the superconductor very, very accurately.
Well, now, I want you to imagine that you live in this superconductor .
And now, you I ask you, what are the laws of physics in that superconductor ?
But it didn't for the physicists of the time until finally, someone began to think about, well, what if what if we live in a cosmic superconductor ?
If we could solve the problem and generate 90 degree superconductor
--I would have bet everything I had that by 40 years, we would have spools of wire for room-temperature superconductors .
And I want to talk about, in particular, a really cool application for superconductors to assist us in the trapping of this basketball in Mars orbit.
But as far as I know, when you're developing electronics, there's conductors and superconductors
