The Time Problem in “Cosmology from Quantum Potential”

Ahmed Farag Ali and Saurya Das recently published a paper in Physics Letters B, “Cosmology from Quantum Potential,” in which they discuss the reasonableness of a liquid quantum potential contra big bang.  You can imagine something like this:

quantum potential

I whole-heartedly believe a number of their “interpretations” in the paper are correct.  However, I also find some of their thoughts extremely puzzling, in light of drawing certain interpretations to their logical conclusion, as one philosopher, Kant, has hundreds of years ago.  I will give a little technical breakdown of the paper —just bear with me through the math/math-speak, which I only include for the sake of the clarity that my colleagues in the sciences would prefer—, and then discuss issues I see.  Continue reading

Distinguishing between Types of Science: Unmixing Metaphysics and Pragmatic Science

I get questions regularly about the bizarre nature of contemporary physics.  I am sure practicing physicists with PhDs get these more regularly than I, yet I occupy an interesting and rare position in the academic disciplinary landscape: I’ve studied science, particularly physics, into the graduate level, and I am actively developing my expertise in the history and philosophy of science, particularly physics, as well as being a lifelong student of more traditional philosophy (e.g., analytic, contemporary, and Eastern).  The question most regularly asked of late has been: What are physicists talking about with all of this “non-verifiable” theory; it sounds like philosophy?  By this, they mean the fact that there is this apparent post-empirical turn, and the lack of requirement of empirical data to substantiate proposed theory.  I’d like to spend some length explaining my thoughts on this, including a suggestion to all practicing scientists, regardless of discipline.

Feynman on the Necessity of Philosophy for the Progress of Physics

Serendipity often leads to some of our most fruitful realizations, creative ideas, and understanding —and are even responsible for our most citation-worthy bits of supporting information.  Such is the case to be discussed here.  It so happened that, just after writing the blog in response to Neil deGrasse Tyson’s ignorant position on philosophy, I read Richard P. Feynman’s The Character of Physical Law to unwind.  The Nobel laureate was always notoriously, even devilishly, anti-philosophy. Continue reading

Teleology and Immaterial Substance after the Physico-Chemical Turn in the Life Sciences

I am posting a paper (click here) I have been playing with for a little while.  I generally don’t post anything that I might publish, but, with some added input and further vision in formulating it, I may be able to turn this into something worth publishing.  The essence of the paper is on vitalism and how teleology has not been stripped out of the original nascent formation (i.e., romantische Naturphilosophie) of the biological discipline.  The paper grew out of my reading of Timothy Lenoir’s The Strategy of Life: Teleology and Mechanics in nineteenth-Century German Biology. Continue reading

Einstein at Leyden (1920): Making Sense of His Reversion to Ether

Einstein is often touted as the physicist to annihilate the idea of the ether.  This is peculiar, because it is as though the world stopped listening to his opinion on the matter prior to his reflections on general relativity (GR).  Einstein never got too excited about proclaiming that an ether, after the conception of GR, is necessary; but he did, nonetheless, make clear arguments, the details, philosophical and historical, I will try to fill in —if only even a few of them.  Continue reading

“Nomos and Physis”: Duquesne University’s 7th Annual Graduate Conference in Philosophy

There was a very nice turnout at Duquesne University’s 7th Annual graduate conference in philosophy (themed “Nomos and Physis”).  A big thanks goes to the Duquesne Department of philosophy and Matt Lovett for running such a well-organized event.  The spread of papers presented was diverse array of subtopics: Phenomenology and Nature; Nature In Itself, Nature for Us; Nature in Ancient Philosophy; Contemporary Ontologies and Nature.  The general sentiment around the room seemed to be that the questions, discussion, and commentary was productive.  Probably the most fascinating element of the conference —I know not if it was by design or happenstance— was that the papers reflected holistic approaches to philosophical considerations pertaining to Nature.   Continue reading

The Mystery of the Varying Cosmological Constant (and What to Possibly Do about It)

I recently read an article by Jesus Mosterin, called “The Unity of Particle Physics and Cosmology?” (pg. 165-176 in The Problem of the Unity of Science edited by Agazzi and Faye). The article is very interesting, because it proposes something I hadn’t heard before, namely, that the Casimir effect might be the phenomenon that is the conceptual key to unifying quantum and cosmological scales.  The idea is that vacuum energies associated with a cosmological constant, Λ, might be the cause of the effect (there are numerous interpretations); but there is/are a problem(s), which has been noted by Steven Weinberg, Alan Guth, and others.  In particular, the one that immediately comes to the fore is the problematic nature of the consequences of a varying cosmological constant.  (Keep in mind that the early universe seemed to have an enormous vacuum energy present, while, now, all we have is this rinky-dink Casimir effect of quantum mechanical origin.)  Continue reading
