The article provides the reader with 
an introduction on the superconductivity. 
A review of this phenomena and 
mechanisms of zero resistance are presented. The article 
also describes high temperature superconductors 
near 90K. Superconductor below its critical 
temperature is discussed. The author gives 
consideration of phonon as particle too.
