Superconductivity -- alchemy for the 21st Century?

An exciting talk and demonstration about superconductivity and its potential practical applications by Ben Williams, Oxford Physics. Superconductivity is a weird property of some materials that has exciting applications both in the lab and outside, in new technologies. The only problem is, we don't quite know what makes superconductivity work! In this talk, you'll see superconductivity in action and find out how, just like modern-day alchemists, physicists are looking to turn the mundane into the magical!
