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)

This is a preprint version of this paper: AIP Conference Proceedings 1841, 020002 (2017) R. E. Kastner Abstract. Time-symmetric interpretations of quantum theory are often presented as featuring "retrocausal" effects in addition to the usual forward notion of causation. This paper examines the ontological implications of certain time- symmetric theories, and finds that no dynamical notion … Continue reading Is There Really “Retrocausation” in Time-Symmetric Approaches to Quantum Mechanics? →

I recently co-authored a paper with TI originator John G. Cramer, which refutes claims that absorption is not well-defined in TI. The paper can be found here: https://arxiv.org/abs/1711.04501

In a nutshell, the measurement problem (MP) is this: given an interaction among quantum systems (such as an unstable atom, atoms comprising a Geiger Counter, atoms comprising a vial of gas, a cat, a friend of Wigner, etc.), which of those interactions constitutes ‘measurement,’ and why? During the past several decades, worries about the MP … Continue reading On the Status of the Measurement Problem: Recalling the Relativistic Transactional Interpretation →

As living creatures on this planet, we go through our daily lives dealing with the unexpected (whether welcome or unwelcome), the surprising, the awkward, the astonishing, the frustrating. Even if we are able to 'go on a vacation' to try to escape from all the chaos, we never really leave it behind. (Is there ever … Continue reading Life Creates Disequilibrium–But How? →
