In 1921 he was able to give a very precise definition of the quantity of heat and the most satisfactory mathematical statement of the law of thermodynamics. Then in 1926 he collaborated with one of his student’s [[Werner Heisenberg]] to develop a mathematical formulation that would describe Heisenberg’s first laws of the new quantum theory (matrix mechanics). This was Born’s most well known work. Born died January 5, 1970 in Göttingen, Germany. | In 1921 he was able to give a very precise definition of the quantity of heat and the most satisfactory mathematical statement of the law of thermodynamics.
