max Planck;Max Karl Ernst Ludwig Planck;Childhood;University; Planck started his physics study at University of Munich in 1874. During his whole scientific career, he only conducted several experiments with Jolly. Before long, he diverted his attention from experiments to theoretical physics. In 1877, he transferred to another school in Berlin. There he studied under Hermann von Helmholtz, Gustav Robert Kirchhoff and Karl Weierstrass. When it came to Hermann, Planck once said: “He prepares nothing before class and always makes some mistakes while calculating so that students find it boring to attend his class.” As to Gustav, he said: “He teaches carefully, but his class is very tedious（冗长的）.” Even so, Planck still developed a sincere friendship with Hermann. Under the influence of Hermann, who was the founder of thermodynamics（热力学）, Planck regarded thermodynamics as his working field.;After graduation;Black body radiation; Physicists are always striving to use the existing knowledge to explain phenomena and principles which are newly found. So a German physicist named Wien（维恩）and a British physicist named Rayleigh（瑞利）successively（相继地）put forward the theoretical formula which could calculate the intensity of radiation according to the wavelength. But they both got a rebuff（碰钉子）. ;The Quantization of Energy; As a physicist, nothing could be more inspiring than the fact that his own theory was confirmed by the experiment. However, Planck was in a dilemma. In a long period of time in history, not only the physics domain but also the science and philosophy domain all held the view that all natural progresses were continuous. ;After 1920;Max Planck;Thanks for watching!
