3.9.2 Interpretation of Quantum Mechanics
Although the mathematical formulation of Quantum Mechanics is rigorous and sophisticated, its current description of reality is not sufficient, including many weired phenomena and conceptions such as the superposition of states, the wave-function collapse or quantum decoherence, and the wave-particle duality. One way of stating this is through the measurement problem: What constitutes a “measurement” which apparently causes the wave-function to collapse into a definite state? Unlike classical physical processes, some quantum mechanical processes, such as tunneling and entanglement, cannot be simultaneously “local”, “causal”, and “real”, but it is not obvious which of these properties must be sacrificed.
As we have already indicated in section 4.5.16, the Duality of Time provides a complete interpretation of Quantum Mechanics, and this will be elaborated further in chapter VI.
