Max+Planck+A3

Max Planck is known for inventing the Quantum Theory. Certain radiation effects could neither be explained by classical mechanics, nor by the theory of electromagnetism. So Max Planck's quantum theory deals with the tiniest things we know, the particles that atoms are made of, which we call "subatomic" particles. Around 1900, Max Planck from the University of Kiel made observations of the radiation of heated materials. He tried to make conclusions from the radiation to the radiating atom. On basis of experimental data, he developed a new formula that later on showed amazing agreement with accurate measurements of the spectrum of heat radiation calle dthe "Black body radiation" which became the basis of the quantum theory. The result of this formula was said that energy is always emitted or absorbed in discrete units, which he called quanta. Planck developed his quantum theory further and resulted in a universal constant, which came to be known as Planck's constant. This quanta discovery revolutionised physics, because it contradicted conservative ideas about the nature of radiation and energy.
