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
Nikolai Kasterin Since 1930 he was a consultant for various scientific institutions including CAGI, Angarsrtoy and the National Institute of Building Materials. Kasterin authored more than forty scientific publications in theoretical physics. He was also known for his works opposing special relativity. Nikolai Kasterin Nikolai Petrovich Kasterin (1869–1947) was a Russian physicist, student of Aleksandr Stoletov. His 1903 doctoral dissertation, portions of which were published in German in the Proceedings of the Royal Academy of Sciences in Amsterdam under the sponsorship of Heike Kamerlingh Onnes, is considered to be a pivotal contribution to multiple scattering theory (MST) by such experts as Paul
