ABSTRACT
Gleick, James Quantum mechanics taught that a particle was not a particle but a smudge, a traveling cloud of possibilities. . .
Heisenberg, Werner We can no longer speak of the behaviour of the particle independently of the process of observation. As a final consequence, the natural laws formulated mathematically in quantum theory no longer deal with the elementary particles themselves but with our knowledge of them. Nor is it any longer possible to ask whether or not these particles exist in space and time objectively. . .
