Superconductivity Superconductivity Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature. It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, in Leiden. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It is characterized by the Meissner effect, the complete ejection of magnetic field lines from the interior of the superconductor during its transitions into the superconducting state. The occurrence of the Meissner effect indicates that superconductivity cannot be understood simply as the idealization of
Heike ondo drums and the taru barrel in his or her ensemble, in intricate drumming techniques. Heike Ondo is accompanied by a kind of shamisen called the Heike Shamisen, which has a shorter neck than most shamisens in Japan, and thus, a higher range. The narrative is quite long and is rarely ever sung in its entirety; key excerpts are chosen for shorter performances. The song is sung by a main singer accompanied by a group of singers who know when to call out the kakegoe (see below). The dance that accompanies Heike Ondo is called Heike Odori (平家踊り). It is simple
