Multi-word Results
| atomic theory |
any of several theories concerning the structure, properties, or behavior of atoms. [2 definitions] |
| big bang theory |
the theory that the universe originated at a fixed point billions of years ago in a cosmic explosion of a mass of hydrogen atoms, and that it has been expanding ever since. (Cf. steady state theory.) |
| Darwinian theory |
Charles Darwin's theory that plants and animals evolved from early primitive life forms with variation caused by natural selection and survival of the fittest. (See evolution.) |
| domino theory |
a theory that if one event occurs, such as the fall of one country under Communist control, a chain of related events will be triggered thereby, such as the fall of neighboring countries. |
| field theory |
in physics, a mathematical description of the effects of physical fields on the distribution and behavior of matter. |
| game theory |
mathematical analysis of strategies for maximizing gains and minimizing losses, applied to games of strategic competition and to corporate, military, and other decision-making problems. |
| kinetic theory |
in physics, the theory that the particles of all matter are in constant motion and that temperature is dependent on the speed of such motion. |
| quantum theory |
a theory in physics that energy radiates or is absorbed in discontinuous quantities, each a multiple of indivisible units or quanta. |
| set theory |
the study of the mathematical properties of, and relations between, sets. |
| steady state theory |
the cosmologic theory, no longer in favor, that new matter is continuously created, causing the universe to expand without requiring cycles of explosion and contraction. (Cf. big bang theory.) |
| theory of games |
see "game theory." |
