I am going to start posting here occasionally about physics and perhaps some  philosophical  items, and selected rants.

My latest reading on the foundations of quantum mechanics  discusses the rift between the positivists and the realists.  I think the basic issue is whether the variables that describe the location, momentum ,and energy of a particle or system are not defined until a measurement is made or whether they have "real" values independent of a measurement.  Non locality, the fact that an action at one place can influence a particle at a distance instantly, has been established by several experiments.  What may be open to question is whether the non locality affects the wave function for a particle or the particle itself.  More later
