Copenhagen interpretation
1, A system is completely described by a wave function \psi, representing the state of the system, which grows gradually with time but, upon measurement, collapses suddenly to its original size.
2,The description of nature is essentially probabilistic, with the probability of an event related to the square of the amplitude of the wave function related to it. (The Born rule, after Max Born)
3,It is not possible to know the value of all the properties of the system at the same time; those properties that are not known with precision must be described by probabilities. (Heisenberg's uncertainty principle)
4,Matter exhibits a wave鈥損article duality. An experiment can show the particle-like properties of matter, or the wave-like properties; in some experiments both of these complementary viewpoints must be invoked to explain the results, according to the complementarity principle of Niels Bohr.
5, Measuring devices are essentially classical devices, and measure only classical properties such as position and momentum.
6,The quantum mechanical description of large systems will closely approximate the classical description. (The correspondence principle of Bohr and Heisenberg.)
