The Importance of Superconductors in MRI Machines
Right now superconductors are primarily used in MRI machines where they make very strong magnetic fields. Because there's no resistance, you can run so much current through this that you can make these super strong electromagnets. Alex: "The actual implications on everyday life just were blew out of the water anything we could imagine"
Alex Kaplan shot to fame on Twitter last week for his thread on the LK-99 superconductor, and why it has the potential to be the most important physics discovery of our lifetime. Today he joins Dan Romero and Erik Torenberg to dig deeper into the LK-99 saga and its broader implications: why the material is so hard to replicate, the citizen journalist aspect and the democratization of science, condensed matter physics, a call for scientific ambition, and more.
