This article compares treatments of the Stern–Gerlach experiment across different physical theories, building up to a novel analysis of electron spin measurement in the context of classical Dirac field theory. Modeling the electron as a classical rigid body or point particle, we can explain why the entire electron is always found at just one location on the detector (uniqueness) but we cannot explain why there are only two locations where the electron is ever found (discreteness). Using non…

Matthias Egg (2021) argues that scientific realism can be reconciled with quantum mechanics and its foundational underdetermination by focusing realist commitments on ‘effective’ ontology. I argue in
The Fundamentality of Fields
There is debate as to whether quantum field theory is, at bottom, a quantum theory of fields or particles. One can take a field approach to the theory, using wave functionals over field

The Disappearance and Reappearance of Potential Energy in Classical and Quantum Electrodynamics
The Hamiltonian of quantum electrodynamics includes an interaction term that represents potential energy of matter. The presence of this potential energy in quantum electrodynamics is at odds with
Possibility of small electron states
Some authors have claimed that there exists a minimum size (on the order of the Compton radius) for electron states composed entirely of positive frequency solutions to the free Dirac equation. Other


On Bohmian Mechanics, Particle Creation, and Relativistic Space-Time: Happy 100th Birthday, David Bohm!
Some more recent developments and extensions of Bohmian mechanics are described, concerning in particular relativistic space-time and particle creation and annihilation.
Studies in History and Philosophy of Modern Physics
Recent discussions of emergence in physics have focussed on the use of limiting relations, and often particularly on singular or asymptotic limits. We discuss a putative example of emergence that

In this letter, we review a manifestly covariant Lagrangian formulation for the dynamics of a classical particle with intrinsic spin and elementary electric and magnetic dipole moments. We then
