... Stars are not born in isolation, but in clusters. This is what astronomical observations of our galaxy (the Milky Way) and other galaxies tell us. The birthplace of stars are the so-called ‘‘molecular clouds’’, i.e., vast, cold volumes of gas (mostly molecular hydrogen and helium, and also complex o ...

... A one-piece cylinder is shaped with a core section protruding from the larger drum. The cylinder is free to rotate around the central axis shown in the drawing. A rope wrapped around the drum, which has radius R1 = 1.0 m , exerts a force F1 = 5.0 N to the right on the cylinder. A rope wrapped around ...

... In either case taking the commutator with the number operator is like taking the time derivative and dividing by the energy of the mode. If a commutator vanishes it vanishes identically for each mode separately. Clearly this cannot happen by just taking a time derivative so neither the electric or t ...
