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?
The Serious Flaws In the Popular Dismissal of Free Will
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
Review: Unseen Reality; Kastner
Thanks Quine for your review!
Kastner’s is one of two “most important” books in physics and cosmology that I’ve read (and in my opinion of course) over the past 7+ years, the other being “Singular Universe” by R. Unger and L. Smolin. How many books have I read addressing the subject of “quantum mysteries”? Paradoxes of the “double slit experiment”, “action at a distance”, “the impact of the observer”, and so on. Except for hidden variables, mostly rejected for good reasons these days, all of the *explanations* are either mere speculative descriptions of phenomena taking place independently of their observation, or they explain them away. Dr. Kastner (building on the work of her mentor John Cramer) does actually explain these phenomena without hidden variables! Whether you like her hypothesis or not, it has to be a contender.
“Unseen Reality” is Kastner’s very good explanation for a popular audience familiar with the basic issues of…

More on Entropy and the Arrow of Time
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
Observation is Measurement, but Measurement is not necessarily “Observation”
“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”
The Arrow of Time from an Overlooked Physical Law
In this post, I'm going to disagree with the following statement by physicist Sean Carroll concerning the nature of time: "The weird thing about the arrow of time is that it’s not to be found in the underlying laws of physics. It’s not there. So it’s a feature of the universe we see, but not … Continue reading The Arrow of Time from an Overlooked Physical Law
