Superconductors are materials that have no resistance to the flow of electricity. The first superconductor was discovered in 1911 when Heike Kamerlingh Onnes cooled Mercury down to 4 degrees Kelvin (-452F, -269C), the temperature of liquid helium. Later John Bardeen, Leon Cooper and John Schrieffer developed a theory of how superconductivity worked. Dubbed “BCS Theory” after the scientists’ last names, it described superconductivity for elements and simple alloys at temperatures close to absolute zero (0 Kelvin, −459.67F, −273.15C); however, BCS theory doesn’t quite explain how superconductivity works at higher temperatures and with more complicated materials. Such an all encompassing theory still eludes modern science and this is a major focus of physics research today. Striped superconductors or “Superstripes” are leading the way in high-temperature superconductivity research.
