Flashes in the Dark


"These considerations lead me to believe that the first human interaction with extraterrestrial life will consist of contact with organisms similar to, if not identical to, earth bacteria or viruses.
...
It is living, breathing, walking, and talking. Only we cannot see it, because it is happening too slowly. Rock has a lifespan of three billion years. We have a lifespan of sixty or seventy years. We cannot see what is happening to this rock for the same reason that we cannot make out the tune on a record being played at the rate of one revolution every century.
...
The rock, for its part, is not even
aware of our existence because
we are alive for only a brief
instant of its lifespan. To
it, we are like flashes
in the dark.
..."

Mysterious Animal


"In sixteenth-century South America, the name [Carbuncle, from the Latin carbunculus , ‘a little coal’] was given by the Spanish conquistadors to a mysterious animal - mysterious because nobody ever saw it well enough to know whether it was a bird or a mammal, whether it had feathers or fur. The poet-priest Martín del Barco Centenera, who claims to have seen it in Paraguay, describes it in his Argentina (1602) only as ‘a smallish animal, with a shining mirror on its head, like a glowing coal . . .’ 

Another conquistador, Gonzalo Fernández del Oviedo, associates this mirror or light shining out of the darkness - two of which he glimpsed in the Strait of Magellan - with the precious stone that dragons were thought to have hidden in their brain. He took his knowledge from Isidore of Seville, who wrote in his Etymologies: 'It is taken from the dragon’s brain but does not harden into a gem unless the head is cut from the living beast; wizards, for this reason, cut the heads from sleeping dragons. Men bold enough to venture into dragon lairs scatter grain that has been doctored to make these beasts drowsy, and when they have fallen asleep their heads are struck off and the gems plucked out.'

Here we are reminded of Shakespeare’s toad (As You Like It, II, i), which, though ‘ugly and venomous, Wears yet a precious jewel in his head . . .’  Possession of the Carbuncle’s jewel offered fortune and luck. Barco Centenera underwent many hardships hunting the reaches of Paraguayan rivers and jungles for the elusive creature; he never found it. Down to this day we know nothing more about the beast and its secret head stone."

Agencies of Magic


"A retired English working-man is sitting at his table with his wife and a friend, a returned British sergeant-major from India. The sergeant-major shows his hosts an amulet in the form of a dried, wizened monkey’s paw... [which has] the power of granting three wishes to each of three people... The last [wish of the first owner] was for death... His friend... wishes to test its powers. His first [wish] is for 200 pounds. Shortly thereafter there is a knock at the door, and an official of the company by which his son is employed enters the room. The father learns that his son has been killed in the machinery, but that the company... wishes to pay the father the sum of 200 pounds... The grief-stricken father makes his second wish -that his son may return- and when there is another knock at the door... something appears... the ghost of the son. The final wish is that the ghost should go away. In these stories, the point is that the agencies of magic are literal-minded... The new agencies of the learning machine are also literal minded. If we program a machine... and ask for victory and do not know what we mean by it, we shall find the ghost knocking at our door."

Imperceptible Chains


"If man made himself the first object of study, he would see how incapable he is of going further. How can a part know the whole? But he may perhaps aspire to know at least the parts to which he bears some proportion. But the parts of the world are all so related and linked to one another, that I believe it impossible to know one without the other and without the whole.

Man, for instance, is related to all he knows. He needs a place wherein to abide, time through which to live, motion in order to live, elements to compose him, warmth and food to nourish him, air to breathe. He sees light; he feels bodies; in short, he is in a dependent alliance with everything. To know man, then, it is necessary to know how it happens that he needs air to live, and, to know the air, we must know how it is thus related to the life of man, etc. Flame cannot exist without air; therefore to understand the one, we must understand the other.

Since everything then is cause and effect, dependent and supporting, mediate and immediate, and all is held together by a natural though imperceptible chain, which binds together things most distant and most different, I hold it equally impossible to know the parts without knowing the whole, and to know the whole without knowing the parts in detail."

- Blaise Pascal (1623 - 1662)

Musings on the Creative Process: Left-Brain / Right-Brain Blending


 "It's always seemed like
a big mystery how nature,
seemingly so effortlessly,
manages to produce so much
that seems to us so complex.
Well, I think we found its secret.
It's just sampling what's
out there in the
computational universe."

- Stephen Wolfram (1959 - )

I apologize beforehand for what might seem like a long and bizarre excursion away from photography; but please bear with me as the following musings are very much in the vein of exploring the "creative process" of photography (well, at least, a glimpse of the creative process I've recently been immersed in!). Specifically, those aspects of the creative process that lie at the cusp of traditional left/right brain functions. Leaving aside the reality of such a dichotomy (e.g., see this recent paper), let us posit that left-brain processes focus more on logic and analytic thinking, and that right-brain processes focus on art and intuition more. Of course, all of us continually engage both sides throughout our waking hours, albeit with our own unique rhythms of shifting/combining focus and modulating relative emphasis. In my case, I live in two - usually quite separate - worlds, deliberately broken up into "what I do during my work week" (employed, as I am, as a physicist at a federally funded research & development center) and "what I do during essentially all available off hours" (which, among other things, has resulted in this photography blog and more fun with my cameras, lenses, filters, and tripods than I deserve in the 45+ years I've been doing photography). Occasionally, as I'm about to do here, I combine my two sides; though not always for the better - you, kind reader, can judge whether I've strayed a bit too far in this case.

"Working with mental images activates a different mode
of consciousness which is holistic and intuitive." 
Henri Bortoft (1938 - 2012)

So many ideas come to mind as I ponder this question: Goethe's Holistic Seeing; Bohm's Implicate Order; and Alexander's (opus on fundamental organizing principles of "life forms") Nature of Order, all come to mind. But I will leave the discussion of these approaches for a later entry. For now, these ideas will have to serve merely as backdrops of my explanation of how I've partly fused my "left-brain/right-brain" activities over the last week or so (I promise to keep it short :). 

At its core, my usual "right brain" approach to photography cannot be simpler: I pick up my camera bag and tripod, head out for a walk to a local park (or just go downstairs to a "studio" I've set up for to experiment with color abstracts), and start shooting. If something catches the eye, I shoot. That's about it. And the less ("left-brain") thinking that is involved, the better (though it sometimes leads to thinking about thinking, which I've written about before). The only important - and almost entirely unconscious - action I take is to choose the time I press the shutter (I've assuming that such minutiae as f-stops, exposure times, filters, and the like are "automatic" and add little to the story I'm trying to tell here). OK, so far, so good.

"So the relationship of each moment in the whole to all the others
is implied by its total content: the way in which it
'holds’ all the others enfolded within it." 
David Bohm (1917 - 1992) 

This is where my several-week-old left-brain machinations come in. While looking over a portfolio of recent abstracts (including those "discovered" in marble and crystals), I ran across a number that fell into the "whole contains other wholes" pictures I described above. I was sitting at the same PC that facilitates both my left-brain (Photoshop) and right-brain (Mathematica) activities, and reflected the same basic type of question I normally reserve for my left-brain: "How can I find the 'best' image?" - meaning one that best satisfies my desire to show "interesting parts" of an image, but in such a way that the whole is still implicitly within sight, "just barely out of reach." I had earlier experimented with breaking up images into thirds and looking for "interesting juxtapositions" (e.g., exchanging the 1st and 2nd panel interchanged, but leaving the 3rd panel fixed). And, while that did lead to some interesting variations, it was also a painstakingly long process. These preliminary experiments were akin to a kind of improvisational play,  wherein I manually dissected each image and created select juxtapositions of interest. Noting that something interesting can actually be found by following this method, my left-brain finally clicked into action.

While the process is still "simple" (relatively speaking), and can - and will - easily be improved upon in coming days and weeks, I wrote a Mathematica function that automatically breaks an image into thirds (i.e., my 3-word alphabet of 'panels' to be used in  constructing new triptychs); applies all possible combinations of (1) leaving the orientation of a given panel unchanged (or as 'original = O'), (2) flipping a panel in the horizontal direction ('HF'), (3) flipping a panel in the vertical direction ('VF'), and (4) rotating a panel 180 deg (i.e., perform a vertical rotation = 'VR'); and assembling the new panels into a triptych with a bit of white space between and on the outside perimeter of the whole image. (90 deg rotations are not allowed, because in order to retain the same aspect ratio, the panels would all need to be square.) The Mathematica function is constrained to not create any triptychs in which the original panel order is left unchanged, since my goal is to find combinations of individually interesting images - in this case, panels - in which the whole, or original image, is only implicit and not directly observable. A bit of counting shows that, with this constraint, there are a total of 320 possible 'panel exchange + rotation/flip' combinations. This is significantly more than I can create by hand, but is easily doable in a few seconds by feeding my Mathematica function a starting image of choice. More specifically (since it is hard to visually digest 320 images at once), I had Mathematica display a smaller array of 16 random triptychs out of the complete set that my right-brain can inspect - and select interesting variants of - "at a glance." 

"No pattern is an isolated entity. Each pattern can exist in the
world only to the extent that is supported by other patterns:
the larger patterns in which it is embedded, the patterns of the
same size that surround it, and the smaller patterns
which are embedded in it."

- Christopher Alexander (1936 - ) 

Two such arrays are displayed at the top of this post, along with - on the right hand side - one of the images I like best. By design, all of the randomly constructed triptychs share the two most important qualities I am searching for: (1) each of the panels is "interesting" (since this cannot be expected to be true of just any image, the starting image must already be specially selected), and (2) the starting image is visible only implicitly, since the viewer is allowed to see only the juxtaposed panels, not in their original order). As for what makes triptych x more/less interesting than triptych y? That's where the right brain jumps back into the process, as it subjectively selects one out of many - just because; though, because of the way my left-brain constructed the samples from which my right-brain is asked to choose (leaving out the "real" image), the right-brain is faced with - what for me, is - an intoxicating aesthetic tension between parts and an implicit whole. Indeed, the pleasure I get from finding and viewing "interesting images" of this sort are a direct analogue of the creative process by which they are spawned. In the same way as (I've just described) my left-brain helps me sort, dissect, operate-on, and create a multiverse of same-but-different sets of images that my right-brain generated the 'starting set' for (by intuitively capturing the original image) - my right-brain now delights in teasing apart the tension between the parts and wholes of images that my left-brain constructed for me (thus revealing "interesting" sets of images otherwise invisible to my own eye). 

Importantly, at least as far as photography - and aesthetics - are concerned, both sides of this creative process are fueled by search, discovery, and selection. That is, a search for a place and time to take a photograph, discovering an image, and selecting how and when to capture it. The only difference between my usual photography and the (admittedly laborious seeming) process described above is the space over which the search, discovery, and selection is conducted: i.e., a meta-space of images constructed out of images already taken vs. the physical world in which an original set of images is captured. The extra delight (I continue to have as I experiment with left-brain / right-brain blending) is that - at least temporarily - both sides of my brains are actively engaged in pursuit of an unchanging goal: to find "interesting images" :)

Here some additional "discoveries" in my left-brain constructed multiverse of meta-images (with more sure to follow)...

Crystalline Physiology


"Molecular biologists usually characterize life by objective properties like self-reproduction, variability and selection, adaptation, and metabolism. These characteristics do not constitute the definition of life but are properties of what we have previously recognized as living (on the Earth) on intuitive and subjective grounds. I think there is no objective definition of life (especially of extraterrestrial life) but only a subjective definition: we will decide that a system is 'living' when we will have relations with it (essentially based on communication) which will appear to us sufficiently rich, interesting, complex. Since any type of communication needs a physical support, the system considered must itself have (or be) a complex physical structure. The living systems on Earth have a hierarchical structure of the following type: living system ... organs ... cells ... 'central memory' (DNA). The transition from one stage to another in this scheme may be contingent and have no logical necessity. One could treat the problem at any of these levels. But molecular biologists are used to building the macroscopic from the microscopic. Since there is no other well established working method, I will thus restrict myself to the aim of finding a model of 'central memory.' It will be required to have the fundamental characteristics of DNA: to be stable, to contain rich information, and to diffuse, thanks for a reading mechanism, this information into the surrounding medium (protein synthesis in the case of the cell). These will be the minimal characteristics of ... model for a crystalline physiology. The places of possible occurrence in nature of this kind of physiology, terrestrial and extraterrestrial rocks, interplanetary dust, white dwarfs and neutron stars are then discussed."

Mathematical Structure



"A famous thorny issue in philosophy is the so-called infinite regress problem. For example, if we say that the properties of a diamond can be explained by the properties and arrangements of its carbon atoms, that the properties of a carbon atom can be explained by the properties and arrangements of its protons, neutrons and electrons, that the properties of a proton can be explained by the properties and arrangements of its quarks, and so on, then it seems that we're doomed to go on forever trying to explain the properties of the constituent parts. The Mathematical Universe Hypothesis offers a radical solution to this problem: at the bottom level, reality is a mathematical structure, so its parts have no intrinsic properties at all! In other words, the Mathematical Universe Hypothesis implies that we live in a relational reality, in the sense that the properties of the world around us stem not form properties of its ultimate building blocks, but from the relations between these building blocks. The external physical reality is therefore more than the sum of its parts, in the sense that it can have many interesting properties while its parts have no intrinsic properties at all."

- Max Tegmark (1967 - )
