Query: Models of measurement for quantum fields and for classical continuous
  random fields   A quantum field model for an experiment describes thermal fluctuations
explicitly and quantum fluctuations implicitly, whereas a comparable continuous
random field model would describe both thermal and quantum fluctuations
explicitly. An ideal classical measurement does not affect the results of later
measurements, in contrast to ideal quantum measurements, but we can describe
the consequences of the thermal and quantum fluctuations of classically
non-ideal measurement apparatuses explicitly. Some details of continuous random
fields and of Bell inequalities for random fields will be discussed.
