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
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…

I’m reblogging this as a counterpoint to a recent book by John Gribbin, “The Time Illusion,” claiming that the ‘block world’ picture of spacetime is settled science. In fact, it is not. There is no real physical evidence for the ‘block world’ model, and there are counterexamples to the claim that relativity requires such a model. The inability of the block world to provide a complete explanation for the 2nd Law of Thermodynamics is another reason to keep an open mind regarding alternative, ‘growing universe’ models.
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 a feature of the laws of the individual particles. So the arrow of time is built on top of whatever local laws of physics apply.”–Sean Carroll, https://www.wired.com/2010/02/what-is-time/
That is a common position, but it could very well be wrong. Specifically, what could be wrong with it is the claim that the arrow of time is “not to be found in the underlying laws of physics.” That claim comes from ignoring the possibility that there could be real, dynamical, irreversible collapse in quantum theory. If there is such collapse, that provides the missing link between physical…

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
