The discoveries in physics — answers to frequently asked questions

At the turn of the XIX and XX centuries, physical and mathematical description of fundamental phenomena seemed almost complete. When the young Max Planck came to 70-year-old professor and told him that he decided to study theoretical physics, he replied: Young man, why do you want to spoil your life, because theoretical physics is almost over … Is it worth taking in such a hopeless thing …? There were, however, difficulties in describing the radiation of heated bodies in the framework of classical physics. To resolve this problem, Planck assumed that radiation is emitted in small portions — quanta. This hypothesis remained obscure for some time, and even the author himself considered it as a conventional mathematical technique of quantization. Gradually, accumulated experimental data on the scattering of light with a change in its wavelength convince skeptics of discreteness of electromagnetic energy. By the end of XX century, the description of the known fundamental phenomena seemed almost completed again…
