Quantum mechanics also produces a relationship between observed quantities, but the principle of uncertainty suggests that the quantity observed is different in the atomic region.
Cause and effect are still related to quantum mechanics but require careful interpretation.
In quantum mechanics the provision of future characteristics such as newtonian mechanics is not possible, since the initial position and momentum of the particle can not be obtained with sufficient accuracy.
The future of the particle is unknown because the present is unknown. Quantities whose relationships are explored by quantum mechanics are: probability.
