Transactional Interpretation

Updated 7/8/26: The published version can be found here: https://www.mdpi.com/1099-4300/28/7/777 The orthodox debate on state symmetrization in QM is, in my view, divorced from the actual physics involved.

I was inspired to write this post after seeing a post by Hammurabi Rubio (a guest post for Romaric Jannel) with a fun revisiting of Wittgenstein’s “beetle in the box” metaphor for language: “Suppose everyone had a box with something in it: we call it a ‘b…

because there seems to be ongoing puzzlement about the quantum/classical divide.

This is a draft of my latest work deconstructing the conventional “Received View” of symmetrized states.

This post offers a paper a wrote a few years ago for a workshop in beautiful Buenos Aires in which we explored the puzzle of distinguishability and indistinguishability in physics.

This animation is based on my publication Maxwell’s Demon Is Foiled by the Entropy Cost of Measurement, Not Erasure, https://www.mdpi.com/2673-9321/5/2/16 (preprint version: https://philsci-archive.pitt.edu/25388/) The Demon gets ready to violate the 2nd…

This paper shows that once we take into account that gas molecules are quantum systems, we find that there is an entropy cost to measuring their positions, and that this is what prevents a Maxwell’s Demon from violating the second law of thermodynamics.
