In December 1957 a paper submitted to the Physical Review journal was published under the simple title “Theory of Superconductivity.” The three authors were J. Bardeen, L. N. Cooper, and J. R. Schrieffer, all from the Department of Physics, University of Illinois, Urbana, Illinois, USA. This paper provided the first proof of zero electrical resistance in 26 metallic elements and many alloys and compounds. Although superconductivity as a physical phenomenon was first observed by Kamerlingh Onnes in 1911, it was not until the advent of quantum mechanics in the 30’s that later theorists were able to give convincing explanations based on the transformations of antisymmetric wavefunctions into symmetric wavefunctions or changing quantum states of fermions into quantum states of bosons. Wherever and whenever electrons become Cooper pairs they act as Bose-Einstein condensates and easily move through the crystal lattices of conductors without losing energy in the form of heat.
However, at high temperatures, the forces that bound the Cooper pairs were overtaken by the forces of thermal vibrations of the crystal lattices. Consequently, the superconducting states disappear. Fortunately, in the 80’s certain types of ceramic materials were found to be superconducting at much higher temperatures. Nonetheless, these newly discovered high temperature superconductivities await the next theoretical enlightenments for providing the second proof of zero drag. Whoever discovers the proof will certainly become the most famous and the richest person(s) on this planet. The temperature convergence of superconductivity might be the same as the temperature of cold fusion. Therefore, a subtle physical connection exists between them. Whoever finds one will also finds the other.
