We are happy to offer teachers and educators “Quantum Levitation Booklet“, a complete experiment guide that includes theoretical background, quantitive experiments, data analysis and much more.
Superconductivity introduces one of the most technically difficult challenges for physicists - designing a measurement setup that will be sensitive to both low (& zero) voltages/resistance and to high voltages/resistance at the same time. The original graph from Onnes's publication from...
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...
