Superconductivity and Cooling Devices

This week we take a look at some supercool science, as Dr Tim Jackson from Birmingham University describes how superconductors work, what they are, and how superconductors are helping astronomers get a clearer view of the universe. Also on the show, Dr Ed Tarte from Birmingham University will discuss applications of superconductors and SQUIDS in the non-invasive discovery of heart defects and observing brain activity in the unborn foetus, and Science Graduate of the Year Alex Mischenko talks about his new environmentally friendly cooling device. In Kitchen Science, Derek Thorne and Professor Ted Forgan show superconductivity in action with a frying pan, some liquid nitrogen and a very strong magnet...

  • Frying pans and Levitation

    This week Derek Thorne is with Professor Ted Forgan from Birmingham University and student helpers Cathy and Dan from Hills Road Sixth Form College in Cambridge. They're going to be using a frying pan and some liquid nitrogen to demonstrate the science of superconductivity.
