Space Between Philosophy and Physics
Khriplovich and Lamoreaux (1997, §2) suggest a very interesting argument that CPT provides the correct notion of “complete reversal” in physics. The background assumption is that “complete reversal” should have…
Detlef Dürr, Shelly Goldstein, and Nino Zanchí once gave a very interesting argument for hidden variables. I’ll give their argument a careful reconstruction. But first, here’s what they say. According…
In Time and Chance, David Albert writes that since the Schrödinger equation involves a first (instead of a second) derivative, “the dynamical laws that govern the evolutions of quantum states in…
A well-known particle physicist’s adage: Ever since the fundamental paper of Wigner on the irreducible representations of the Poincaré group, it has been a (perhaps implicit) definition in physics that an elementary particle…
In quantum mechanics, certain unitary operators have been understood since the time of Wigner in terms of spacetime symmetries. Why? The foundation for this kind of thinking has an interpretive and…
