Liquid Vortex


"My soul is an entangled knot,
Upon a liquid vortex wrought
By Intellect in the Unseen residing,
And thine doth like a convict sit,
With marline-spike untwisting it,
Only to find its knottiness abiding;
Since all the tools for its untying
In four-dimensional space are lying,
Wherein they fancy intersperses
Long avenues of universes,
While Klein and Clifford fill the void
With one finite, unbounded homoloid,
And think the Infinite is now at last destroyed. "

James Clerk Maxwell (1831 - 1879)

Electromagnetic Phenomena


"We shall never know what Faraday would have achieved had he mastered mathematics, but, paradoxically, his ignorance may have been an advantage. It led him to derive his theories entirely from experimental observation rather than to deduce them from mathematical models. Over time, this approach gave him a deep-seated intuition into electromagnetic phenomena. It enabled him to ask questions that had not occurred to others, to devise experiments that no one else had thought of, and to see possibilities that others had missed. He thought boldly but would never commit himself to an opinion until it had withstood the most rigorous experimental testing. As he explained in a letter to Ampère: I am unfortunate in a want to mathematical knowledge and the power of entering with facility any abstract reasoning. I am obliged to feel my way by facts placed closely together."

Entropic Melodies


"The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations - then so much the worse for Maxwell's equations. If it is found to be contradicted by observation - well, these experimentalists do bungle things sometimes. But if your theory is found to be against the Second Law of Thermodynamics I can give you no hope; there is nothing for it to collapse in deepest humiliation."

Arthur Stanley Eddington (1882 - 1944)

Postscript. One of the first major publications that some of my work was featured in was Black & White magazine, way back in issue #41 (Feb 2006). The images were from what I called my "entropic melody" series. But the "melody" part applies equally to the images (as in "living melodies of otherwise visibly decaying parts") as it does to the - still ongoing - process of creating them (on a vastly different space and time scale). Though I like to think of my "synesthetic landscape" series as my longest "in progress" portfolio, the truth is that - having started "only" in 2009 - it takes a back seat to something I believe I'll never tire of: finding "life" in lifelessness. And so, on a recent "long weekend" vacation with my wife and youngest son (also a photographer), and armed with this spur-of-the-moment self-reflection, I found my eye and lens trained not (entirely) on the natural beauty in the West Jefferson area of North Carolina (of which there is plenty to be had, to be sure!), but rather on the regions' splendors of human-created and now neglected decaying beauty. Looking over the 30 or so "keeper shots" I returned home with, no less than 25 of them are of nothing but "withered but beautifully decrepit" sentinels - and occasional palimpsests - of  times past. And, for the photographer, a glimpse of a longer-term "melody" playing out in an always evolving aesthetic landscape. I will be featuring a few of my favorites from this short-much-too-short trip in the coming days.

Our Quixotic Purpose


"We all behave like Maxwell’s demon. Organisms organize. In everyday experience lies the reason sober physicists across two centuries kept this cartoon fantasy alive. We sort the mail, build sand castles, solve jigsaw puzzles, separate wheat from chaff, rearrange chess pieces, collect stamps, alphabetize books, create symmetry, compose sonnets and sonatas, and put our rooms in order, and all this we do requires no great energy, as long as we can apply intelligence. We propagate structure (not just we humans but we who are alive). We disturb the tendency toward equilibrium. It would be absurd to attempt a thermodynamic accounting for such processes, but it is not absurd to say we are reducing entropy, piece by piece. Bit by bit. The original demon, discerning one molecules at a time, distinguishing fast from slow, and operating his little gateway, is sometimes described as “superintelligent,” but compared to a real organism it is an idiot savant. Not only do living things lessen the disorder in their environments; they are in themselves, their skeletons and their flesh, vesicles and membranes, shells and carapaces, leaves and blossoms, circulatory systems and metabolic pathways - miracles of pattern and structure. It sometimes seems as if curbing entropy is our quixotic purpose in the universe."

Time, Process, and Eternity


"Happy is the man who can recognize in the work of to-day a connected portion of the work of life and an embodiment of the work of Eternity. The foundations of his confidence are unchangeable, for he has been made a partaker of Infinity. He strenuously works out his daily enterprises because the present is given him for a possession.

Thus ought man to be an impersonation of the divine process of nature, and to show forth the union of the infinite with the finite, not slighting his temporal existence, remembering that in it only is individual action possible, nor yet shutting out from his view that which is eternal, knowing that Time is a mystery which man cannot endure to contemplate until eternal Truth enlighten it."

(1831 - 1879)

Escher, Paul Klee, and a Turtle, Oh My...

...to which the tagline can read: a snapshot of the corner shelf in the study of a photographer prone to a gentle madness (where the "madness" refers to the deep passion for books, and is part of the title of a book - not shown - that describes that passion). My home, much to wife's dismay, is filled with books; all kinds of books; a veritable (countable) infinity of books, though a demonstrably smaller infinity than, say, the infinity represented by the categories one can imagine by which these books can all be distinguished, and that they collectively represent an intertwined wisdom about. Short books, and long; dime-store paperbacks and coffee-table-sized hardcovers; textured papers and glossy; those with pictures and others with only text; books about history and culture; philosophy, art, religion and Zen; the collected works of Chekov, Ellery Queen, Stanislaw Lem, and Philip K. Dick (with scattered books and tapes by Alan Watts); travelogues about conquests of Everest, Antarctica, and Ayahuasca; biographies of Maxwell, Dirac, and Feynman, as well as Ansel, Cartier-Bresson, and two Westons (Edward and Brett); books on self-organized vortices of consciousness and anything else mused on by Hofstadter; Christopher Alexander's magnum opus; and more books on physics and photography than most dreams can conjure over a dozen or more nights!

Borges famously introduced a ridiculously wondrous taxonomy of all knowledge in his 1942 essay "The Analytical Language of John Wilkins" (which he claims to have taken from an ancient Chinese encyclopedia, Celestial Emporium of Benevolent Knowledge). The categories of animals alone includes: 

"Those that belong to the emperor;
Embalmed ones;
Those that are trained;
Suckling pigs;
Mermaids (or Sirens);
Fabulous ones;
Stray dogs;
Those that are included in this classification;
Those that tremble as if they were mad;
Innumerable ones;
Those drawn with a very fine camel hair brush;
Et cetera;
Those that have just broken the flower vase;
Those that, at a distance, resemble flies."

And to this whimsical classification I introduce another that leads directly to the title of this blog: an image of the books (and of whatever else might fall onto your camera's sensor) that sits directly in front of you as you work on your images on a computer. Arbitrary? To be sure. Meaningful? Only to the extent that it is a well-formed query that has a definite answer; it may even provide a glimpse of what "interests one" most, right now, as in "I need this and that reference to be by my side." If we are what we read (and eat, and see, and do, ...) then surely our most immediate literary/visual companions are what we are at this moment (so long as they assembled on the shelf by themselves).

So my soul, right now, evidently needs these 15 books to be within easy reach as I muse and ponder and tinker with tones and forms on my computer: 9 are related to photography, 3 to art, and 1 each to mathematics, physics, and an "uncategorizable" category onto itself (best defined by its title: The Art of Looking Sideways); well, these books and an image of an old, wise sea turtle who - like a Zen sage -  quietly reminds me of the transience of all categories and classifications, and that, eventually, even my desire to look sideways will drift into a timeless void.

What do you, kind reader, find on your easy-to-reach shelf of books and memorabilia?

The Click of the Shutter Button...and A Deep Mystery

Physics is replete with "revolutions" in world-view that emerged after someone was brilliant enough - and brave enough - to question the foundations of "common wisdom." Witness Copernicus and his assertion that the Earth was not the center of the universe; Newton and his realization that the same force that binds us, as physical beings, to this planet is the same one that keeps the planets in their orbits; James Clerk Maxwell and his curiosity about the relationship between electricity and magnetism; Einstein and his stubbornly persistent analysis of the deep meaning of simultaneity; and Louis de'Broglie (along with a handful of others, including Einstein) puzzling over the difference between particles and waves. The list goes on and on, of course. In each case, a seemingly mundane - but sincere - questioning of an "obvious" fact (as Tommy Lee Jones says to the Will Smith character in the movie Men in Black, as he tries recruiting Smith's character to join MIB: "Everybody knew the Earth was flat...") led to a radical conceptual reordering of how we think of the universe, and our role in it.

While I do not propose any such radical reconceptions of our world in this humble little blog entry, I am going to suggest that the "creative act of photography" affords us an opportunity to ask a disarmingly trivial question (that may indeed alter how we perceive and interact with our environment, and ourselves). I will preface the question by first positing that one of the deepest mysteries confronting science today (apart from questions pertaining to the standard model of physics, string theories, or loop quantum gravity) is the nature and origin of consciousness. Consciousness is something we all, presumably, possess; yet is something about which - apart from knowing we possess it, and guessing that our experience of it is "pretty much the same" as that of any other humanly conscious creature - we have little or no real understanding.

Three of the more cogent (and often widely disagreeing) discussions of consciousness are (1) Consciousness Explained (by Daniel Dennet), (2) The Conscious Mind (by David Chalmers), and (3) I am a Strange Loop (by Douglas Hofstadter). None of these, of course, "explains" consciousness; but all are great at stimulating further discussion.

My particular interest, at least for purposes of this blog entry, is that aspect of consciousness that has to do with intentionality; i.e., the (apparently) willful decision to "act" (such as when we decide to "press the shutter" of a camera). Before I ask that question, however, consider this "simple" experience: I am holding a ball in my hand, which, at some point in time, for whatever reason, I decide to throw up in the air a few inches, and catch again. A trivial everyday act. Yet an utter mystery, as far as both fundamental physics and our understanding of consciousness is concerned. Just as there is no "physics" (of which I am aware), no equations or simulations, that accounts for why a small sphere located at some space-time position (x,y,z,t) suddenly "decides" to move against the gravitational field; there is no theory of consciousness that "explains" why I chose to throw up a ball. Oh, I certainly register the fact that the ball has been thrown - i.e., I am "conscious" of having done so after I've done it - but I have utterly no idea why I chose to throw it at the time I threw it. Bejamin Libet has studied this fascinating phenomenon in the laboratory (see Mind Time), and has found that consciousness is actually far from a vehicle of willful intentionality; indeed, its real purpose may be to negate possible actions, not - as we have been taught by convention - to create them.

Why am I choosing the words I'm typing now, and not others? How are they forming in my mind (and, while we are on the subject, what is mind?) I am aware of having "written", but I am at a complete loss as to explaining why I chose the words I did; nor am I able to "explain" why they emerged when they did. They "come out of me," as if by magic; and I have little, or no, "control" over what they are or when they will form. My conscious self reflects back on their existence, but appears blissfully unaware of the process by which they were created.

So what does all of this have to do with photography? Everything, really; the creative act of photography is a microcosm of our general state of conscious experience. In my previous blog entry ("Experiential Flow in Photography"), I wrote of how the best photography is usually done when the photographer is in a state of flow; in which many of the attributes of "self awareness" - or consciousness itself - vanish. In truth, though, every single photograph is a result of (at least an instant's worth) of a "lack of consciousness." When I press the shutter, at that instant, I am completely unaware of why I have done so. It is important to understand exactly what I mean by this. I do not mean that I have idea of what I am doing. Clearly, I am out taking photographs, and I am fully aware of this, even as I press the shutter. But when my finger physically moves down on the shutter button to initiate capture, I have absolutely no idea why that act did not occur a microsecond before or a microsecond after. Indeed, if Libet's research is to be believed, the best I can say is that I become aware of having pressed the shutter button only after I have done so, but in no other way has my consciousness been an active participant in the process that led up to pressing the button.

The act of taking a picture thus presents the photographer with both a puzzle (about who we really are, apart from the role we play in helping the universe take a picture of itself) and an opportunity to learn something about the universal core of the creative process and consciousness itself.

What I sometimes do (when I can retain enough of my self-awareness to remember to do this;-) is to try to minimize the time between which I have pressed the shutter and at which I become conscious of having pressed the shutter. This is not at all as "easy" at it may sound. It requires a razor-sharp Zen-like focus on the process and the moment; and is, at heart, obviously antithetical to the "photographic flow" process, as described in my earlier blog entry. It harbors a bit of a paradox: the deeper one is immersed in the "flow," the less able one is to "reflect" on the process and "understand" the unconscious instant of capture; on the other hand, the "easier" it is to reflect on the process, the less likely it is that the process being reflected upon is the one of deepest interest (i.e., "flow"). Paradox - unavoidably it seems - always lurks around questions about consciousness; and just as mysteriously, it lies at the very heart of the creative process.
