Quantum Spin Doctors Dissect Exotic States of Matter
... Under quantum mechanics, particles sometimes behave like waves, and waves sometimes behave like particles. While it is possible in classical mechanics to characterize the state of a particle completely—using properties such as mass, charge, velocity, and position—in quantum mechanics such certainty ...

It follows that these, the laws of quantum mechanics, cannot be the whole story; either the measurement postulates cannot be separated off from the dynamics, or the state is incomplete.4 Bohr's way out of this dilemma was to c ...
