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
Atomic Sub Noah Talbot was the Human Sub (though this was changed to the Atomic Sub after the war). After World War II, the Atomic Sub became a member of the Roundtable of America with Knight Watchman and Ultiman. During the Criss-Cross Crisis (In which Earths A and B came into contact with one another), The Atomic Sub bravely sacrificed himself to save the two Earths, and was respected as a hero on both worlds. In the distant future, the remains of the Atomic Sub were used to construct the cyborg known as Bezerker. As well as super-strength and flight, the Atomic
