I*ve been a fan of Pilot Waves for many years. We*ve made great
   progress in the Copenhagen and other popular interpretations of
   Quantum Mechanics, such as many worlds, but a lot of these are
   based on a perceived need to distance ourselves from Maxwell * a
   perceived *break* with the past, as all old formulas get their
   new (but not necessarily improved) Quantum Mechanical
   equivalent. As we get closer to making practical devices using
   quantum level technologies, having a proper understanding of
   quantum mechanics is crucial for us to continue. The analoges of
   electricity, pressure, behavior of fluids, etc * all lining up
   nicely with each other in practical engineering fields (a water
   computer is no more difficult than an computer of electrons;
   space is the main issue) * all are primarily expressed in waves,
   and rightly so. Excess emphasis on the perceived *spookiness* of
   quantum level interactions does help fund the almost religious
   mystique of all things *quantum*; it has become a magic word in
   many circles*. but it simply means *counting how much/how many*.
   The idea of separate little things we can count is *very* useful
   and helpful * and indeed, for many things, we can *count* and
   act *as if* things are isolated from other things. but they*re
   not. The complex interaction of all things is obvious from the
   very nature of the beginnings of the Universe; we were once all
   one and there is no *nothing* inbetween things, even though we
   are often taught that in school. There is a *something* in the
   *middle* of things * there always is. This doesn*t mean the path
   will be easy; we may still depend on a particle zoo view of
   things simply because so much wonderful work and research has
   been done in that area * and there is no reason to abandon it
   all. But an understanding of the *context* within which this
   *apparent* particles are living in * * as expressions of waves *
   not *clouds* of statistics* raising math to a level that
   Pythagoras*s followers would fully recognize as their religion *
   will most definitely benefit future research and technologies,
   in my opinion. Kenneth Udut Naples, Florida USA Via :
