Lecture 33 - Stimulated Absorption
... Today we will work through the concepts of spontaneous and stimulated emission, first propounded by Einstein in 1916-1917: i. Spontaneous emission is just like radioactive decay, with less energetic byproducts: an atom in an excited state has a finite probability of decay per unit time, a decay prob ...

As Sakurai indicates [4], the proposed electrostatic AB effect may be understood as an example of the energy-frequency relation E = h, according to which the rate of phase generated depends on the energy. If we can arrange for the electrostatic potential energy qV of a charged particle to differ al ...

Bohr–Einstein debates
The Bohr–Einstein debates were a series of public disputes about quantum mechanics between Albert Einstein and Niels Bohr. Their debates are remembered because of their importance to the philosophy of science. An account of the debates was written by Bohr in an article titled ""Discussions with Einsteinon Epistemological Problems in Atomic Physics"". Despite their differences of opinion regarding quantum mechanics, Bohr and Einstein had a mutual admiration that was to last the rest of their lives.The debates represent one of the highest points of scientific research in the first half of the twentieth century because it called attention to an element of quantum theory, quantum non-locality, which is absolutely central to our modern understanding of the physical world. The consensus view of professional physicists has been that Bohr proved victorious, and definitively established the fundamental probabilistic character of quantum measurement.
