Fields
Main article: Fields of science Fields of science are widely-recognized categories of specialized expertise within science, and typically embody their own terminology and nomenclature. Each field will commonly be represeneted by one or more scientific journal, where peer reviewed research will be published The Meissner effect The Meissner effect is the expulsion of a magnetic field from a superconductor. Walther Meissner and Robert Ochsenfeld discovered the phenomenon in 1933 by measuring the magnetic field distribution outside tin and lead samples. The samples, in the presence of an applied magnetic field, were cooled below what is called their superconducting causes a magnet to levitate above a superconductor Superconductivity is a phenomenon occurring in certain materials generally at very low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field . It was discovered by Heike Kamerlingh Onnes in 1911. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical<<Table of Contents Science refers to any systematic knowledge-base or prescriptive practice that is capable of resulting in a prediction or predictable type of outcome. In this sense, science may refer to a highly skilled technique or practice | Next>>
