Superconductor up close (using SEM)

We can easily build a true hoverboard with superconductors. Superconductors Superconductors are a perfect example for a Quantum Physics that is macroscopic, large and accessible to play with.  Superconductivity is created by having discrete energy levels AND by having a...

In 1911, Dutch physicist and Nobel Laureate Heike Kamerlingh Onnes discovered that when you cool the element mercury (Hg) in liquid helium to a temperature of -270°C (-454°F) , it exhibits a phenomenon of zero electrical resistance, which he then called superconductivity. For...

Do we understand what makes a superconductor? Yes, but not entirely. The phenomenology (or the quantitive description of the phenomenon) of superconductivity was quickly developed after first discovered in 1911 (e.g. by London, Abrikosov, Meissner) and scientists could soon describe...
