The complimentary principle and the determinism of quantum physics
Complimentary principle: all entities in our physical word exhibit both wave and particle properties, these two aspects are complimentary. Better we know one aspect of the particle, worst is our knowledge about the other.
Example: If we know the position (particle aspect), we have no idea about the momentum which determines the wavelength (wave aspect)
classical Newtonian determinism (mechanistic view) does not hold!
- strong argument against predetermined Universe
In quantum mechanics the future becomes a statistical (or probabilistic) issue
We have only probabilities for predicting each of the possible futures (nature will select among them, with probabilities revealed by the theory of quantum mechanics)
