Steven Weinberg on quantum troubles

Post date: Jan 5, 2017 3:48:31 PM

It is interesting to read Weinberg on the "Trouble with Quantum Mechanics". He gives a charmingly old-fashioned discussion of the problem, and his piece reads more like something from a philosopher of physics, rather than a physicist.

It is all Copenhagen, or instrumentalists, or many-worlds, or GRW. No discussion that we now know much more about the way wavefunction collapse happens, or weak measurements, or the debates about quantum Bayesianism, or anything past, say, 1988. The entire literature of quantum discoveries for the past 30 years is a closed book.
