On the theory of brownian motion volume 324, issue 2, pages 3781, 1906, original citation. The ones marked may be different from the article in the profile. Albert einstein 18791955 was a renowned theoretical physicist of the 20th century, best known for his theories of special relativity and general relativity. He also made important contributions to statistical mechanics, especially his treatment of brownian motion, his resolution of the paradox of specific heats, and his connection of fluctuations and dissipation. President, fuller research corporation, vernon hill, illinois. List of scientific publications by albert einstein wikipedia. Einstein coefficients are mathematical quantities which are a measure of the probability of absorption or emission of light by an atom or molecule. Thus mass is oscillating spacetime, which results from the superposition of two countermoving spacetime waves. The einstein a coefficients are related to the rate of spontaneous emission of light, and the einstein b coefficients are related to the absorption and stimulated emission of light. We provide a semiclassical optics derivation of einsteins rate equations ere for a twolevel system illuminated by a broadband light field, setting a limit on their validity that depends on the spectral properties of the light field.
