I recently co-authored a paper with Transactional Interpretation (TI) originator John G. Cramer, which derives the Born Rule (quantum probability rule) for radiative processes (emission and absorption) in a simple and transparent way, based on the Wheeler-Feynman-Davies'absorber' theory of radiation. It also shows that absorption is indeed perfectly well-defined in TI (contrary to skeptical claims … Continue reading Paper with John Cramer on Absorption in TI →

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? →

Let me begin by stating up front: I do not claim to know whether we do or do not have free will. We may have free will, or we may not. The only strong claim I wish to make here is the following: if we do not have free will, it is not for the … Continue reading The Serious Flaws In the Popular Dismissal of Free Will →

This is somewhat technical. It's for those interested in the puzzle of how we get the irreversible processes we see all around us from laws that are supposedly reversible. The trick: they are not all reversible. A crucial part of the physics of Nature involves an irreversible step that has long been neglected. The paper … Continue reading More on Entropy and the Arrow of Time →

“By final [state], we mean at that moment the probability is desired—that is, when the experiment is “finished.” –Richard P. Feynman, Feynman Lectures, Vol. 3 The challenge of defining measurement is evident in the excerpt from Feynman’s famous Lectures in Physics, quoted above--when is the experiment 'finished'??. This remark arises in his discussion of when … Continue reading Observation is Measurement, but Measurement is not necessarily “Observation” →
