Welcome! Here you will find information about the latest, relativistic version of the transactional interpretation of quantum mechanics, 'RTI', blog posts, and an opportunity for informal discussion. The transactional interpretation (TI) is a new way of understanding what's behind the formalism of quantum physics. I have just completed the follow-up book to Understanding Our Unseen … Continue reading Welcome!

Important New Book on Math Education
Bernice Kastner is a math educator whose innovative approach has helped to transform classrooms and enable many students to gain confidence and mastery in math. (She also happens to be my mother.) Her new book, The Role of Language in Teaching Children Math, is now out: https://www.austinmacauley.com/us/book/role-language-teaching-children-math From the publisher: "It can be difficult to … Continue reading Important New Book on Math Education
A critical look at popular ‘retrocausation’ claims. Do they hold up?
In this publication, I address popular uses of the term 'retrocausation' in connection with quantum theory, and find that there is much that needs to be corrected and clarified. Much of the discussion in the literature on this topic involves inconsistencies and equivocation about what retrocausation really is, and about what it can do. In … Continue reading A critical look at popular ‘retrocausation’ claims. Do they hold up?
Interview with Adam Alonzi on RTI, Schrodinger’s Cat, Time’s Arrow, Free Will

Visit to Buenos Aires, Grupo de Filosofía de las Ciencias.
I had fun in Buenos Aires last summer with the great people in the Grupo de Filosofía de las Ciencias. Here is my talk on how to understand the emergence of classicality from the quantum level in the context of statistical approaches. https://youtu.be/kvXYmB2qj88
Why “making sense of quantum theory” by denying that theories are about the world does not really work
This post points out a little-known but powerful and important argument from Joe Henson regarding a proposed interpretation of quantum theory known as "Qbism". Qbism is currently advocated primarily by Fuchs, Mermin, and Schack. Henson's argument discloses a crucial fallacy in Qbism's claim to demonstrate that quantum mechanics is a local theory, where a 'local' … Continue reading Why “making sense of quantum theory” by denying that theories are about the world does not really work

What is the quantum/classical divide?
A talk given at the University of Buenos Aires in June 2017 on the difference between classical systems and quantum ones: https://www.youtube.com/watch?v=kvXYmB2qj88&feature=youtu.be (Note: Some of the slides were missing text here and there due to a compatibility issue; the correct version is provided here: Baires 2017 slides)
