A Brief Tour of Cold,hases of matter. The chapter reviews the race to liquefy the atmospheric gases including oxygen, nitrogen, argon and ending with the liquefaction of helium and the discovery of superconductivity. James Dewar’s liquefaction of hydrogen and the development of his “Dewar flasks” is also mentioned. The
