A history of Quantum Mechanics

The neutron was not discovered until 1932 so it is against this background that we trace the beginnings of quantum theory back to 1859 In 1859 Gustav Kirchhoff proved a theorem about blackbody radiation A blackbody is an object that absorbs all the energy that falls upon it and, because it reflects no light, it would appear black to an observer...
