| Copenhagen interpretation | has competing theory Copenhagen interpretation |  |
| has definition The view of quantum mechanics holding that prior to the measurement, a system has no physical existence and is describable only in terms of the probability of each possible result of a measurement. After a measurement the physical system exists in one and only one of its possible states. | |
| is an instance of quantum mechanics interpretation | |
| quantum mechanics | has applicability microscopic scales of atoms and subnuclear particles but not restricted to this | |
| has constraint certain quantities (e.g. energy, angular momentum, light) can only exist in certain discrete amounts, called quanta. | |
| has implication physical systems must be described in terms of probabilities. | |
| has equation Any physical system, such as an atom, may be viewed as existing as a combination of its possible states, each of which has a certain probability. | |

| has author or reasearch group | |
| has domain a field of research | |
