Bose–Einstein condensation NEW PROBLEMS
... Although interactions are extremely important in a real gas, the problems are made tractable and the essential physics is retained by assuming an ideal gas of noninteracting particles. We also assume that the states are non-degenerate. The chemical potential, which is a measure of the change of inte ...

... J. J. Thomson found electrons in atoms (1897) by extracting them from a gaseous discharge and bending them in magnetic fields. This let him find their charge/mass ratio. Thomson suggested (1898) that atoms consist of positively charged lumps of matter with electrons embedded in them. ("Raisin puddin ...

However, when we reach p = l, where l = 1, 2, 3, ..., the coefficient multiplying Ap+1 (or Al+1 ) is zero and the recursion is satisfied for non-zero Al+1 . The final catch is to notice that, in order for the series to terminate, we ha ...

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.
