Max Planck was told that there was nothing new to be discovered in physics. He was about to embark on a career in physics that would set that idea on its ear. Planck was an extremely successful ...

In 1899 Max Planck became a professor at the University of Berlin, after nine years at the University of Munich and Kiel University, in Germany. In his research there, he turned to a thermodynamic ...
