Atomic, molecular, and optical physics electron is treated quantum mechanically. In low speed collisions the approximation fails. Classical Monte-Carlo methods for the dynamics of electrons can be described as semi-classical in that the initial conditions are calculated using a fully quantum treatment, but all further treatment is classical. Atomic, Molecular and Optical physics frequently considers atoms and molecules in isolation. Atomic models will consist of a single nucleus that may be surrounded by one or more bound electrons, whilst molecular models are typically concerned with molecular hydrogen and its molecular hydrogen ion. It is concerned with processes such as ionization, above threshold ionization and excitation
What the Bleep Do We Know!? to measure the position and momentum of subatomic particles... this only applies to sub-atomic particles—a rock doesn't need you to bump into it to exist. It's there. The sub-atomic particles that make up the atoms that make up the rock are there too." Hobbs also discusses Hagelin's experiment with Transcendental Meditation and the Washington DC rate of violent crime, saying that "the number of murders actually went up". Hobbs further disputed the film's use of the ten percent of the brain myth. David Albert, a philosopher of physics who appears in the film, has accused the filmmakers of selectively editing
