Even if you don’t understand the physics of superconductors (and I don’t) this still looks pretty cool.
If you want to learn more about the underlying physics on your commute, you can try listening to the final chapter of the best of the Feynman lectures as an audio book. I did. I’m not sure it helped. I kept feeling something pass over the top of my head, but perhaps some small bit of it stuck.
