Demystifier reacted to A. Neumaier's post in the thread Undergrad Physicists disagree wildly on what quantum mechanics says about real… with
Like.
See, e.g., the discussion in the last two sections of D. Wallace, The quantum theory of fields, and his Reading List in Philosophy of... -
Demystifier reacted to Chiara's post in the thread Undergrad On the Quantum Mechanics of Entropic Forces with Like.
He showed in his paper that the entropy of black holes, their temperature, and their mass/energy, taken together, imply the field...
