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.  Given that I have been, for a long time, working with another philosopher of physics on a scientifically-technical philosophical paper that forcefully argues some of the same points, I will not comment on those items I agree with, so as not to give anything away from unpublished work.

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.

Thoughts on a Fractured Reality

There is some discussion going on in the blogosphere (and youtube) about whether the world we live in is pluralistic or monistic.  Critical Animal’s blog (click here) contains a list of some of these blog posts.  As with most ideas, I am of many minds about the issue.  While I think I would prefer a world that is as envisioned by the zeitgeist of the Enlightenment, axiomatically and formally structured from the bottom up, it is becoming very difficult to see how the world could be anything other than pluralistic.  What I will do in the following is lay out why it seems to me that the world is pluralist, and then lay out why I think the human mind has such a natural bias toward mosism.  On the latter point, I think most readers will agree with me that the commonsense disposition —the disposition of any ole jane or joe on the street— is one inclined toward a single truth, possibly slightly more nuanced, in the axiomatic manner I described; and so I will spend some time explaining why this is probably the case.

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.

Examining and Thinking Through “The Simplest Possible Universe”: Part II

This is the second in a series of blog posts about a work done by Dr. David Lee Cale, professor at West Virginia University.  Cale, a polymath, is chiefly a philosopher, trained in physics, political science, mathematics, economics, and numerous other disciplines, holds a Ph.D. in philosophy, an M.B.A., a B.A. in political science, and is ABD in economics, and is a notable ethicist.  The work of his being examined is “The Simplest Possible Universe,” a monograph that synthesizes ancient Greek and Scholastic styles of thinking with modern physical insight.  The work is striking, in that its brand of creativity is not common in modern intellectual enterprises.  Retaining the good sense and substance of modern physics, Cale employs modes of thinking that are on loan from times nearly forgotten.  The objective of this blog series is to deconstruct the monograph, examine its components, and assess the merits of each, redoubting where possible.  At the end, if efficacious, an attempt at resynthesis of the project, consequent upon the conceptual retooling, will be made.  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

Einstein, Poincaré, and Kant: Between Galison and Yourgrau

I find something deeply puzzling about Peter Galison’s Einstein’s Clocks, Poincaré’s Maps: Empires of Time.  In particular, this wonderful book develops the contextual settings in which the relativistic physics of Einstein’s and Poincaré’s physics were conceived, as well as the intellectual link that existed between them.  In brief, Galison makes clear the role that technology played in formulating the ideas of Einstein and Poincaré.  The hope of Europe was to establish a synchronized system of clocks, for economic reasons (e.g., train services without collisions due to timing issues), political reasons (e.g., von Moltke maintained that a strong relationship existed between German national unity and einheitzeit), and general technology concerns (e.g., inductance in wires can cause incredible and varying lag times in signal transmission, as a function of distance and current among other variables, in telegraphy).  Poincaré, having been educated at the École Polytechnique, possessed the “factory stamp” that their students possessed: even the mathematicians were essentially “mechanicians”. Einstein, educated at one of Europe’s leading technology universities and working in a patent office, machine patents abound, and Poincaré being thoroughly immersed in problems dealing with telegraphy (electrodynamics) and clock synchronization, Galison makes the claim that relativity theory is largely a product of the machine-minded science of the nineteenth century.   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
