Max Planck 
Origin and Development of the Quantum Theory [EPUB ebook] 
Being the Nobel Prize Address Delivered Before the Royal Swedish Academy of Sciences at Stockholm, 2 June, 1920

You may know that the Quantum Theory revolutionized our perception of matter on the atomic scale, but did you know that its founder, Max Planck, himself didn’t believe it?This short read is Planck’s address to the Royal Swedish Academy of Sciences after winning the Nobel prize. He displays how his Quantum Theory came into existence. It was not the result of a single lab experiment and a conclusion, but an inspection of overwhelming evidence from various works of immortal names like Bohr, Hertz, Ostwald, Einstein, and others.Planck unveils secrets in the scientific community, explains why his own theory was inconceivable to the classical physicist, and first mentions the famous dispute between Quantum Theory and Relativity in this eye-opening book."After some weeks of the most intense work of my life, clearness began to dawn upon me, and an unexpected view revealed itself in the distance.""The quantum would have to play a fundamental role in physics, heralding the advent of a new state of things, destined to transform completely our physical concepts." ~Max Planck
