Physics atoms and molecules. The three areas are grouped together because of their interrelationships, the similarity of methods used, and the commonality of their relevant energy scales. All three areas include both classical, semi-classical and quantum treatments; they can treat their subject from a microscopic view (in contrast to a macroscopic view). Atomic physics studies the electron shells of atoms. Current research focuses on activities in quantum control, cooling and trapping of atoms and ions, low-temperature collision dynamics and the effects of electron correlation on structure and dynamics. Atomic physics is influenced by the nucleus (see, e.g., hyperfine splitting), but intra-nuclear
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
