It's always a pleasure to talk with Jeffrey Mishlove. In this interview we talked about the Transactional Interpretation and related ideas: https://youtu.be/E6NNWdVCQZU
I gave a talk on the Transactional Interpretation and how it solves quantum paradoxes at the "Copenhagen and Beyond" Conference at Chapman University, CA (Oct. 18, 2019). The title was "Quantum Paradoxes: To Resolve or To Acquiesce?" It can be found here: https://digitalcommons.chapman.edu/cib-2019/cib/schedule/10/
A recent paper by Frauchiger and Renner has brought to light a serious problem with conventional approaches to quantum theory, by deriving a contradiction using those approaches. In FR Paradox Kastner 10.17.19 I argue that the paradox shows that quantum theory leads to absurdities and inconsistencies unless there is a clear physical criterion for 'measurement'. … Continue reading Latest incarnation of the Schrödinger Cat Paradox forces a new view of quantum theory
The so-called 'quantum eraser' is an experiment that has prompted widespread confusion. In fact, it is nothing more than a photonic version of the EPR experiment. Nothing is erased, and there is no necessary retrocausation or 'temporal nonlocality,' beyond standard EPR correlations. I attempt to clear up the confusion in this paper, which has now … Continue reading The ‘Delayed Choice Quantum Eraser’ Neither Erases Nor Delays
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
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?

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
This post is a critique of an interpretational approach to quantum theory known as "Qbism." Qbism is currently advocated primarily by Fuchs, Mermin, and Schack. Here, I discuss a little-known but powerful and important argument from Joe Henson regarding Qbism. Henson's argument discloses a crucial fallacy in Qbism's claim to "save locality" in quantum theory; … Continue reading Why “making sense of quantum theory” by denying that theories are about the world does not really work
