omega tau - English only

How do scientists uncover phenomena and explain their connections? How do engineers design machines, methods and infrastructure? At omega tau, experts give detailed answers. Over the last ten years, we have produced over 350 episodes in which we dug deeper, until we ran out of questions. Join us on our journey through the world of science and engineering: the closer you look and listen, the more interesting things get.


episode 285: Superconductivity

Guest: Pierre Bauer    Host: Markus Voelter    Shownoter: Kolja Dummann

Superconductivity, the ability of a material to carry electrical current with zero resistance, is a surprising property of nature, which man has been able to exploit in many ways, in particular, for high-performance magnets. Those are used in magnetic resonance imagers, but also in colliders and fusion reactors. In this episode we discuss the basics of superconductivity and its uses with Pierre Bauer, a superconductor engineer at ITER.
