[If you’re interest in Michael Polanyi, who was a world-class physical chemist and an Anglican philosopher of science who in about 1955 wrote Personal Knowledge, a paean of praise to the beauty and precision of science and at the same time a systematic deconstruction of old-style scientific “objectivism,” inspiring Kuhn but much better (if you ask me), go to per caritatem and check out a number of lucid Polanyi posts there — and here.]
I have a new motto for this post, from the Cartalk guys, who claimed to be (supposedly) quoting Albert Einstein! “Once you can convert all the matter in the universe into something that is nothing, the rest is easy….” The mass-energy questions asked below convert into matter-field questions, and these ain’t little questions!
This weblog and the lively conversations we’ve had here over the past few months have propelled me into some intense productivity on my own work. Thanks!
I’ve been working on several scholarly essays concerning Plato’s Ion and Aristotle’s Poetics, and once these are scheduled for publication, I’ll start resuming my posts here on Plato’s Ion. (This just gives you some more time to absorb the ideas on literary theory in the Ion posts — and in the good stuff under “Pages.” Of course I’ll welcome comments on what’s already here, in the meantime.)
Then there’s everything I’ve learned from the physicists — and from the molecular biologist! — who’ve engaged so generously with me here: on quantum mechanics (for 60 fact-packed pages!), on Plato, on the paradigm shift from Newton to Einstein, on the soul, on method in science, on “ink-and-paper vs Hamlet,” and on “gnomes with shovels“!
I’ll have a posting for you soon on the Higgs Boson, detailing what you’ve taught me and how I want to use it in a book for general readership about the science/cultural studies divide. It will also be about how we might find our way through this dreadful “social construction of reality” impasse, an impasse I believe arises strictly within the context of our own Anglo-American intellectual tradition — and because of its particular and distinctive precoccupations.
Our habitual framework of assumptions leads us into misunderstandings when we are assimilating thought that evolved on the Continent, concerning what is being claimed (our word) about “reality” and what “exists.” (The denial of “an external world” emerges during the assimilation into our context, I take it, and does not occur in the original Continental contexts, so when Sokal and Brimont attacked some prominent French thinkers, they were the wrong targets if “social constructionism” was the enemy.)
But right now, until my Higgs Boson post appears, I’d like to address another question to those in the sciences, a question which arises for me when I am contemplating the standard theory, and especially the Higgs field, and remembering what Gavin and David said about the “medium,” as it were, through which electro-magnetic and other quantum waves propagate (i.e. “the universe,” they seemed to say).
Now, it seems that finding the Higgs boson would help to clarify what “mass” is. I get that. But what in the world, then, is “energy”?
In other words, is it the case that the question of what energy “is” has been clarified already for the physics community?
Like, for instance, is it true that even where we have those “vacuums” out in “deep space,” nonetheless all of it is thought to be “filled” with the Higgs energy field? And, I gather, with all of the other quantum energy “waves,” which in a sense seem to diffuse away into infinity? (This is why wave-particle duality is observed even when the wave is split and sent over large distances before being recombined and measured, and why entanglement phenomena manifest even when the pair of particles are separated by very large distances?)
And all of this leads me to the whole question of “being without any mass,” like photons. What does “massless” mean? How can a photon be massless and yet manifest as a particle? How can a massless particle make a “ping” on a screen? (Or is that just what happens with electrons and other particles with mass?)
Energy, I’m assuming (right?), is by definition without mass, since energy converts into mass, and vice versa. E = Mc^2.
And, okay, I’m sorry, but if energy is massless and if it fills “empty” space, in what sense then are we still saying that the science of physics is an empirical science? A science that deals strictly with “physical reality”? How can energy be taken to be a physical and empirical thing, if it has no mass and takes up no space in any material sense? (At least until it is converted into a particle with mass….) Yes, I know that you have plenty of evidence that energy exists, but how is it a material thing? And if it is, then how are we defining material or physical reality these days? (Not the way it’s done on some of the science blogs….)
Okay, I’ve done some research and I see mass vs energy comes down to the difference between fermions and bosons? So deep space is filled with a boson wave field?
Thanks for any insights and any good links you can give me on this — which I realize to be the sort of question that only a humanist, most likely, would ask…. (Maybe this kind of consideration is the reason that it seems more physicists today self-identify as “Platonists” or as “positivists,” than as “realists”?) P. S. Found a fascinating piece on mass-energy equivalence in the Stanford Encyclopedia of Philosophy — see the section on Philosophical Interpretations.
And don’t suppose, my gentle readers, that I’ve forgotten about the “soul,” either, or about the issues involving theism vis-a-vis science. I’m just getting everything “set up” here, to tackle these inquiries you’ve made, with some degree of precision….
