Light, Shadow, and Geometry

"The phenomenon which I have now briefly mentioned appears to me to partake of the character of the marvelous, almost as much as any fact which physical investigation has yet brought to our knowledge. The most transitory of things, a shadow, the proverbial emblem of all that is fleeting and momentary, may be fettered by the spells of our "natural magic," and may be fixed for ever in the position which it seemed only destined for a single instant to occupy.

This remarkable phenomenon, of whatever value it may turn out in its application to the arts, will at least be accepted as a new proof of the value of the inductive methods of modern science, which by noticing the occurrence of unusual circumstances (which accident perhaps first manifests in some small degree), and by following them up with experiments, and varying the conditions of these until the true law of nature which they express is apprehended, conducts us at length to consequences altogether unexpected, remote from usual experience, and contrary to almost universal belief. Such is the fact, that we may receive on paper the fleeting shadow, arrest it there, and in the space of a single minute fix it there so firmly as to be no more capable of change, even if thrown back into the sunbeam from which it derived its origin."

- Henry Fox Talbot (1800 - 1877)

Luminous Beings

"'Don’t try to hurry,' he said. 'You’ll know in due time and then you will be on your own, by yourself.' 'Do you mean that I won’t see you any more, don Juan?' 'Not ever again,' he said. 'Genaro and I will be then what we always have been, dust on the road.' I had a jolt in the pit of my stomach. 'What are you saying, don Juan?' 'I’m saying that we all are unfathomable beings, luminous and boundless. You, Genaro and I are stuck together by a purpose that is not our decision.' 'What purpose are you talking about?' 'Learning the warrior’s way. You can’t get out of it, but neither can we. As long as our achievement is pending you will find me or Genaro, but once it is accomplished, you will fly freely and no one knows where the force of your life will take you.' 'What is don Genaro doing in this?' 'That subject is not in your realm yet,' he said. 'Today I have to pound the nail that Genaro put in, the fact that we are luminous beings. We are perceivers. We are an awareness; we are not objects; we have no solidity. We are boundless. The world of objects and solidity is a way of making our passage on earth convenient. It is only a description that was created to help us. We, or rather our reason, forget that the description is only a description and thus we entrap the totality of ourselves in a vicious circle from which we rarely emerge in our lifetime.'"

Light Prancing

"The artist’s world is limitless.
It can be found anywhere far from
where he lives or a few feet away.
It is always on his doorstep."

- Paul Strand (1890 - 1976)

Postscript. These images were all captured within minutes of each other in a garage near a local farmer's market this past weekend, as I was waiting for my wife to gather our grocery bags to go shopping. I have written before about how mesmerizing the "abstract cacophony" of shimmering reflections off car's hoods and hubcaps are to a photographer's eye 😊 What is hard to express in words (though I'm obviously trying, obliquely), is how joyful these few minutes' worth of prancing back and forth in-between park cars inevitably are to my soul (I look forward to my "light prancing" almost as much as the delicious recipes my wife cooks up with what we gather at the market!) My only regret (as usual) is that all I had with me was an iPhone.

"Light makes photography.
Embrace light.
Admire it.
Love it.
But above all, know light.
Know it for all you are worth,
and you will know
the key to photography."

- George Eastman (1854 - 1932)

Action Potential

"At this moment, in this place, the shifting action potential in my neurons cascade into certain arrangements, patterns, thoughts; they flow down my spine, branch into my arms, my fingers, until muscles twitch and thought is translated into motion; mechanical levers are pressed; electrons are rearranged; marks are made on paper.

At another time, in another place, light strikes the marks, reflects into a pair of high-precision optical instruments sculpted by nature after billions of years of random mutations; upside-down images are formed against two screens made up of millions of light-sensitive cells, which translate light into electrical pulses that go up the optic nerves, cross the chiasm, down the optic tracts, and into the visual cortex, where the pulses are reassembled into letters, punctuation marks, words, sentences, vehicles, tenors, thoughts.

The entire system seems fragile, preposterous, science fictional."

Web of Time

"This web of time, the
strands of which approach
one another, bifurcate,
intersect or ignore each
other through the centuries,
embraces every possibility.
We do not exist in most of them.
In some you exist and not I,
while in others I do,
and you do not"

- Jorge Luis Borges (1899 - 1986)

A Vast Pattern

"Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I too can see the stars on a desert night, and feel them. But do I see less or more? The vastness of the heavens stretches my imagination - stuck on this carousel my little eye can catch one - million - year - old light. A vast pattern - of which I am a part... What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little about it. For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?"

- Richard Feynman (1918 - 1988)

Perceive the Inconceivable

"What dreaming does is

give us the fluidity to

enter into other worlds by

destroying our sense of

knowing this world.

He called dreaming a journey

of unthinkable dimensions,

a journey that, after making us

perceive everything we

can humanly perceive,

makes the assemblage point

jump out side the

human domain and

perceive the inconceivable. "

- Carlos Castaneda (1925 - 1998)
The Art of Dreaming

A Magical Illusion

"You have seen that the universe is at root a magical illusion and a fabulous game, and that there is no separate 'you' to get something out of it, as if life were a bank to be robbed. The only real 'you' is the one that comes and goes, manifests and withdraws itself eternally in and as every conscious being. For 'you' is the universe looking at itself from billions of points of view, points that come and go so that the vision is forever new."

- Alan Watts (1915 - 1973) 

The Sentinel

"Think of such civilizations,
far back in time against the
 fading afterglow of creation,
masters of a universe so
young that life as yet had come
only to a handful of worlds.
Theirs would have been
a loneliness of gods
looking out across infinity
and finding none to
share their thoughts."

- Arthur C. Clarke (1917 - 2008)

 The Sentinel

This Place is a Dream

"This place is a dream.
Only a sleeper considers it real.
...
A man goes to sleep in the town
where he has always lived,
and he dreams he's living
in another town.

In the dream, he doesn't remember

the town he's sleeping in his bed in.
He believes the reality of the dream town.

The world is that kind of sleep.
...

We began as a mineral.

We emerged into plant life

and into animal state,
and then into being human,

and always we have
forgotten our former states,

except in early spring when we
slightly recall being green again.

That's how a young person turns

toward a teacher. That's how a baby leans

toward the breast, without knowing the secret

of its desire, yet turning instinctively.

Humankind is being led along an evolving course,

through this migration of intelligences,

and though we seem to be sleeping,

there is an inner wakefulness

that directs the dream,

and that will eventually startle us back

to the truth of who we are."

- Rumi (1207 - 1273)

Postscript. The triptych consists of three "quick grabs" with my iPhone during the trip my family and I took to the Pacific Northwest this past summer (e.g., see this blog entry). The left- and right-most images show the play of sunlight (reflected off the door of our car) with the pavement as we were going to breakfast one day in Sequim, WA. The middle panel shows a similar play of light (this time reflected off a kettle on our stove) with the stucco walls of the kitchen in the cabin we rented in the northern cascades. Most of my photography is quasi-deliberate, by which I mean that most of my images arise during planned "expeditions" (such as to a local park, or hikes on a family vacation 😊 using my "real" camera. But some of my favorite images - such the ones in this triptych - are captured purely by happenstance, and when my conscious "attention" lies elsewhere (such as on, say, getting breakfast at a restaurant or the first sip of coffee in the morning). Of course, any distinctions I may choose to draw among these various states of being and attention are, of course, at best illusory, and, at worst, utterly meaningless. Even as my "eye" looks toward the path to a restaurant or at the handle of a coffee kettle, my "I" never ceases to revel at the magic of light, color and form that surrounds us in each moment in time and space!

Why is the sky blue?

"[Why is the sky blue?] ... It’s a question every toddler asks, but it is also one that most great scientists since the time of Aristotle, including da Vinci, Newton, Kepler, Descartes, Euler, and even Einstein, have asked... One of the things I like most about this explanation—beyond the simplicity and overtness of the question itself—is how long it took to arrive at correctly, how many centuries of effort, and how many branches of science it involves.

Aristotle is the first, so far as we know, to ask the question about why the sky is blue, in the treatise On Colors; his answer is that the air close at hand is clear and the deep air of the sky is blue the same way a thin layer of water is clear but a deep well of water looks black. This idea was still being echoed in the 13th century by Roger Bacon. Kepler too reinvented a similar explanation, arguing that the air merely looks colorless because the tint of its color is so faint when in a thin layer. But none of them offered an explanation for the blueness of the atmosphere. So the question actually has two, related parts: why the sky has any color, and why it has a blue color.

...

The sky is blue because the incident light interacts with the gas molecules in the air in such as fashion that more of the light in the blue part of the spectrum is scattered, reaching our eyes on the surface of the planet. All the frequencies of the incident light can be scattered this way, but the high-frequency (short wavelength) blue is scattered more than the lower frequencies in a process known as Rayleigh scattering, described in the 1870’s. John William Strutt, Lord Rayleigh, who also won the Nobel Prize in physics in 1904 for the discovery of argon, demonstrated that, when the wavelength of the light is on the same order as the size of the gas molecules, the intensity of scattered light varies inversely with the fourth power of its wavelength. Shorter wavelengths like blue (and violet) are scattered more than longer ones. It’s as if all the molecules in the air preferentially glow blue, which is what we then see everywhere around us.

Yet, the sky should appear violet since violet light is scattered even more than blue light. But the sky does not appear violet to us because of the final, biological part of the puzzle, which is the way our eyes are designed: they are more sensitive to blue than violet light.

The explanation for why the sky is blue involves so much of the natural sciences: the colors within the visual spectrum, the wave nature of light, the angle at which sunlight hits the atmosphere, the mathematics of scattering, the size of nitrogen and oxygen molecules, and even the way human eyes perceive color. It’s most of science in a question that a young child can ask."

This Explains Everything (John Brockman, ed., 2013)

 

A Moment or Two to Just Be

"While I sit here, I don’t beg to be somewhere else; I’m not pulled away by the future or by the past. I sit here, and know where I am. This is very important. We tend to be alive in the future, not now. We say, ‘Wait until I finish school and get my PhD; then I’ll really be living.’ Once we have it – and it wasn’t easy to get – we say to ourselves, ‘I have to wait until I have a job for my life to really begin.’ Then after the job a car, and after a car a house. We aren’t capable of being alive in the present moment. We tend to postpone being alive to the future, the distant future, we don’t know when. It’s as if now is not the moment to be alive. We may never be alive at all in our entire life. The only moment to be alive is in the present moment."

- Thich Nhat Hanh (1926 - )

Postscript. The picture above was captured not with my "real" camera but with my iPhone, whose ability to capture scenes such as this continues to impress. I was on a short "day job" related trip to the beautiful town of Newport, RI, and had a few precious moments of magic hour light at the Sachuest Point National Wildlife Refuge (just a few miles from the center of town). I was initially despondent over having not taken my real camera (and rationalized the "complexities" of mixing business with pleasure; what, with a laptop and pounds of technical notes already stuffed into my carry-on). I then got even more melancholy over having neglected to take my other "real" camera that I bought specifically for this purpose (an absurdly tiny but equally as absurdly capable digital camera I wrote about earlier this spring). But then I remembered Thich Nhat Hanh's sage advice (quoted above). Stilling my mind as best I could, and clutching my iPhone, I managed to find a moment or two to just be. 

Universal Causation

"But the scientist is possessed by the sense of universal causation. The future, to him, is every whit as necessary and determined as the past. There is nothing divine about morality; it is a purely human affair. His religious feeling takes the form of a rapturous amazement at the harmony of natural law, which reveals an intelligence of such superiority that, compared with it, all the systematic thinking and acting of human beings is an utterly insignificant reflection. This feeling is the guiding principle of his life and work, in so far as he succeeds in keeping himself from the shackles of selfish desire. It is beyond question closely akin to that which has possessed the religious geniuses of all ages."

- Albert Einstein (1879 - 1955)

Energy Field

"Colors are not possessions;

they are the intimate revelations
of an energy field…
They are light waves with
mathematically precise lengths,
and they are deep,
resonant mysteries with
boundless subjectivity."

- Ellen Meloy (1946 - 2004)
The Anthropology of Turquoise

The Matrix of All Matter

"I regard consciousness as fundamental, matter is derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness. There is no matter as such; it exists only by virtue of a force bringing the particle to vibration and holding it together in a minute solar system; we must assume behind this force the existence of a conscious and intelligent mind. The mind is the matrix of all matter."

- Max Planck (1858 - 1947)

Patterns

"To live on a day-to-day basis is insufficient for human beings; we need to transcend, transport, escape; we need meaning, understanding, and explanation; we need to see over-all patterns in our lives. We need hope, the sense of a future. And we need freedom (or, at least, the illusion of freedom) to get beyond ourselves, whether with telescopes and microscopes and our ever-burgeoning technology, or in states of mind that allow us to travel to other worlds, to rise above our immediate surroundings.

We may seek, too, a relaxing of inhibitions that makes it easier to bond with each other, or transports that make our consciousness of time and mortality easier to bear. We seek a holiday from our inner and outer restrictions, a more intense sense of the here and now, the beauty and value of the world we live in."

- Oliver Sacks (1933 - 2015)

Postscript #1. The triptych consists of images I captured one day last summer after my wife parked her car in a garage near a local farmer's market. I was mesmerized by the "organized cacophony" of shimmering reflections off other car's hoods and hubcaps that arranged - and revealed - themselves to anyone interested in looking. Though I lamented not having my "real" camera, I was happy to have my iPhone to capture this lovely visual feast! Yet another gentle reminder that we must always be on alert to the universe's ceaseless wonders. And, though I rarely talk about the "nuts-and-bolts of photography on my blog (and much prefer posting images and musings than highlighting what f-stop I used), here's a small - hopefully useful - foray into the "nuts-and-bolts" department: to better prepare for unpredictable contingencies (i.e., for when I'm out and about without my usual shoulder and/or back-breaking warehouse-in-a-bag assortment of cameras, lenses, and filters), I recently purchased a tiny - almost babyish-looking - camera; albeit one that is fully functioning! Since it is designed to fit in even a child's pocket (!), I've resolved to always have it on my person when leaving the house for any reason. For those of you curious, it's Canon's G1X Mark III, which is best described as an ultra-miniaturized mirrorless version of their (older) 80D DSLR. While its fixed-lens is neither particularly bright nor sharp, the sensor is effectively the same one used on the 80D; yep, an APS-C sensor in a body that fits inside a shirt pocket! You can check out a review here. So far, I'm loving it, though have yet to post any pictures captured by it. But I suspect that'll soon change :)

Postscript #2. For those of you saddened by not having Oliver Sacks' sage wisdom around anymore (though his books forever enshrine his genius), there is a wonderful new biography available, called Oliver Sacks: His Own Life. Highly recommended!

Geometry and Space

"It is well known that geometry presupposes not only the concept of space but also the first fundamental notions for constructions in space as given in advance. It only gives nominal definitions for them, while the essential means of determining them appear in the form of axioms. The relationship of these presumptions is left in the dark; one sees neither whether and in how far their connection is necessary, nor a priori whether it is possible. From Euclid to Legendre, to name the most renowned of modern writers on geometry, this darkness has been lifted neither by the mathematicians nor the philosophers who have laboured upon it."

- Bernhard Riemann (1826 - 1866)

Light of Skye

 "The light of love, the purity of grace,
The mind, the Music breathing from her face,
The heart whose softness harmonised the whole —
And, oh! that eye was in itself a Soul!"

- Lord Byron (1788 - 1824)

Postscript. As photo-safari opportunities have dwindled (and though I do have a growing backlog of house-studio-facilitated abstracts to work on, as time permits), much of my "photo time" nowadays consists of discovering and reworking old images. This one is from the summer of 2009, captured during the first trip my wife and I took to Scotland; specifically, South Ronaldsay, one of the preternaturally beautiful Orkney Islands off Scotland's northeastern coast. The light there, as in all of Scotland, is not entirely of this world!

Waves

 "You are a function of what the whole universe is doing in the same way
that a wave is a function of what the whole ocean is doing."

- Alan Watts (1915 - 1973)

Vibrant Hum

"At a certain point, you say to the woods, to the sea, to the mountains, the world, Now I am ready. Now I will stop and be wholly attentive. You empty yourself and wait, listening. After a time you hear it: there is nothing there. There is nothing but those things only, those created objects, discrete, growing or holding, or swaying, being rained on or raining, held, flooding or ebbing, standing, or spread. You feel the world's word as a tension, a hum, a single chorused note everywhere the same. This is it: this hum is the silence. Nature does utter a peep - just this one. The birds and insects, the meadows and swamps and rivers and stones and mountains and clouds: they all do it; they all don't do it. There is a vibrancy to the silence, a suppression, as if someone were gagging the world. But you wait, you give your life's length to listening, and nothing happens. The ice rolls up, the ice rolls back, and still that single note obtains. The tension, or lack of it, is intolerable. The silence is not actually suppression: instead, it is all there is."
