The Philosophy of Vacuum Part 25. Physicists will find it extremely interesting, covering, as it does, technical subjects in an accessible way. For those with the necessary expertise, this book will provide an illuminating and authoritative exposition of a many-sided subject." -John D. Barrow, Times Literary Supplement. | Vacuum or Holomovement 233 emerging from this consideration is that in the hologram the local features of the original object are carrried non-locally. Thus what is local in one representation the original object becomes non-local in another the hologram and vice versa. But the relation between these two frames of reference is such that the structural content is the same in both frames. What makes the object frame more fundamental to us is that the object has meaning for us in the classical world which we take to be a preferred frame. Normally this is taken to be a Newtonian frame. Clearly this is not an absolute frame. It is preferred simply because of its utility and not because it has any absolute significance. Relativity has explained all that. Relational properties actually play an important role in quantum mechanics. One can see this most clearly in the causal interpretation see Bohm and Hiley 1987 . To explain this idea let us first recall that measurement in quantum theory is in general active and not passive. This point can be brought out most clearly again through the causal interpretation but it is already implicit in the usual approach. It arises because of the nature of the quantum potential which is such as to cause the system and the measuring apparatus temporarily to fuse to form an inseparable whole before the apparatus finally evolves into one of its distinct final states. Each of these final states is correlated to a final state of the system which is in general different from its initial state. It is as if the measured properties of the particle are in general created by the measurement itself. The properties not being measured also undergo uncontrollable and unpredictable changes and it is this that is ultimately responsible for the uncertainty principle. In other words in quantum mechanics measurement is a transformation in which both system and apparatus actually participate. Thus although the particles have intrinsic properties the .
