BCS: 50 Years is a review volume edited by Leon Cooper, a 1972 Nobel Laureate in Physics, and Dmitri Feldman of Brown University, first published in 2010. The book consists of 23 articles written by outstanding physicists, including many Nobel prize-winners, and presents the complete theory of superconductivity - a phenomenon where the electrical resistance of some metallic materials suddenly vanish at temperatures near absolute zero. Background Sixty years ago, in 1957, John Bardeen, Leon Cooper and John Robert Schrieffer finally pieced together the puzzle of superconductivity, explaining in detail its mechanism and the associated effects. The BCS theory, named after the three scientists, won Professor Cooper the Nobel Prize in Physics in 1972, which he shared with John Robert Schrieffer and his teacher, John Bardeen.
