ALBERT EINSTEIN
Quantum theory of radiation of different one of the most prominent scholars of XX century. - Albert Einstein (18791955) Einstein first introduced the concept of the quantum physics of light. Before him, no one imagined that the light field is a collection of elementary light fields of photons , or light quanta emitted by independent bodies and regardless well absorbed by them. He created the quantum theory of light and spread the ideas of quantum theory to the physical processes that are not directly related to light.
In 1905, there was a remarkable work of Einstein's theory of photoelectric effect - electrons from atoms by irradiation. 15 this work it was shown that the photoelectric effect can only be explained by assuming that the light is a collection of particles - photons that hitting the electron pull it out of the atom. Next, the quantum theory of radiation of different one of the most prominent scholars of XX century. - Albert Einstein (18791955) Quantum theory of radiation of different one of the most prominent scholars of XX century. - Albert Einstein (18791955) Important to study the properties of atoms and their particles is most well-known works of Einstein - theory of relativity and the quantum theory of the nature of energy.
In 1905, Einstein published a paper on the Brownian motion. Other works have contributed to the development and justification of the quantum Bose-Einstein statistics , which, together with the Fermi-Dirac statistics has played a very important role in quantum theory. Einstein is also the author of theory of specific heat of solids. In 1921, for his services to Theoretical Physics , and especially for his discovery of the laws of the photoelectric effect , Einstein was awarded the Nobel Prize. Scientific papers of Einstein played a big role in the development of modern physics - quantum electrodynamics , nuclear physics and nuclear physics , elementary particle physics , cosmology , astrophysics.
