Atoms of Space


"It all starts from the idea that space—like matter—is made of discrete elements. And that the structure of space and everything in it is just defined by the network of relations between these elements—that we might call atoms of space. It’s very elegant—but deeply abstract ... And what we’re seeing here is the emergence of space and everything in it by the successive application of very simple computational rules. And, remember, those dots are not atoms in any existing space. They’re atoms of space—that are getting put together to make space. And, yes, if we kept going long enough, we could build our whole universe this way ... all this is built from pure computation. But like fluid mechanics emerging from molecules, what emerges here is spacetime—and Einstein’s equations for gravity ... Our computational rules can inevitably be applied in many ways, each defining a different thread of time—a different path of history—that can branch and merge ... But as observers embedded in this universe, we’re branching and merging too. And it turns out that quantum mechanics emerges as the story of how branching minds perceive a branching universe."

Morphic Resonance


"The sudden appearance of all the Laws of Nature is as untestable as Platonic metaphysics or theology. Why should we assume that all the Laws of Nature were already present at the instant of the Big Bang, like a cosmic Napoleonic code? Perhaps some of them, such as those that govern protein crystals, or brains, came into being when protein crystals or brains first arose. The preexistence of these laws cannot possibly be tested before the emergence of the phenomena they govern."

Electric Universe


"The watcher’s eyes are likely to swivel forward in a sequence of stately turns as the screen’s pixel glows: each quarter-ounce mass of eyeball tugged by six flat muscles, in a glissando slide within the slippery fat lining the orbital cavity. The eye blinks, the widened pupils are in position, and the incoming electromagnetic waves roar in. Ripping through the thin layer of the cornea, they decelerate slightly, with their outermost edges forming a nearly flat plane as they travel inward, carrying the as-yet-undetected signal from the screen deep into the waiting human. The waves continue through the liquid of the aqueous humor and on to the gaping hole of the pupil. The human may have squinted to avoid the glare, but human reflexes work at the rate of slow thousandths of a second and are no match for these racing intruders. The pupil is crossed without obstruction. The stiff lens just below focuses the incoming waves even more, sending them into the inland sea of the jellylike vitreous humor deeper down in the eye. A very few of the incoming electric waves explode against the organic molecules in their way, but most simply whirl through those soft biological barriers and continue straight down, piercing the innermost wrapping of the eyeball, till they reach the end-point of their journey: the fragile, stalklike projection from the living brain known as the retina. And deep inside there, in the dark, barely slowed from their original 670 million mph, the waves splatter into the ancient, moist blood vessels and cell membranes, and something unexpected happens. An electric current switches on."

Atomic Poetry


 "We must be clear that when it comes to atoms,
language can be used only as in poetry.
The poet, too, is not nearly so concerned with
describing facts as with creating images
and establishing mental connections."

A Space-Time Event


"There is nothing mysterious about space-time. Every speck of matter, every idea, is a space-time event. We cannot experience anything or conceive of anything that exists outside of space-time. Just as experience precedes all awareness and creative expression, the visual language of our photographs should ever more strongly express the fourth dimensional structure of the real world.
...
I feel all things as dynamic events, being, changing, and interacting with each other in space and time even as I photograph them.
...
What you see is real - but only on the particular level to which you've developed your sense of seeing. You can expand your reality by developing new ways of perceiving."

Wynn Bullock (1905 - 1975)

"To be" is to Inter-Be

"If you look deeply, you will see that there is a cloud floating in this sheet of paper. Without a cloud, there will be no rain; without rain, the trees cannot grow; and without trees, we cannot make paper. The cloud is essential for the paper to exist. If the cloud is not here, the sheet of paper cannot be here either. So we can say that the cloud and the paper inter-are. 'Interbeing' is a word that is not in the dictionary yet, but if we combine the prefix 'inter-' with the verb 'to be,' we have a new verb, inter-be.
...
If we look into this sheet of paper even more deeply, we can see the sunshine in it. If the sunshine is not there, the forest cannot grow. In fact, nothing can grow. Even we cannot grow without sunshine. And so, we know the sunshine is also in this sheet of paper. The paper and the sunshine inter-are. And if we continue to look, we can see the logger who cut the tree and brought it to the mill to be transformed into paper. And we see the wheat. We know the logger cannot exist without his daily bread, and therefore the wheat that became his bread is also in this sheet of paper. And the logger’s father and mother are in it too. When we look in this way, we see that without all these things, this sheet of paper cannot exist.
...
Looking even more deeply, we can see we are in it too. This is not difficult to see, because when you look at a sheet of paper, the sheet of paper is part of our perception. Your mind is in here and mine is also. So we can say that everything is in here with this sheet of paper. You cannot point out one thing that is not here – time, space, the earth, the rain, the minerals in the soil, the sunshine, the cloud, the river, the heat. Everything co-exists with this sheet of paper. That is why I think the word inter-be should be in the dictionary. 'To be' is to inter-be. You cannot just be by yourself alone. You have to inter-be with every other thing. This sheet of paper is, because everything else is."

The Heart of Understanding

Postscript. As is likely obvious to even casual visitors to my humble blog during the last week, I am currently immersed in the world of cymatics (although my wife thinks of it as more of an obsession). "Cymatics" refers to the study of sound and vibration; specifically, when the two are combined in a way that creates complex patterns in different media such as sand, water, or - what Swiss physician Hans Jenny (who coined the term) liked to use - corn starch in water. For example, if a metal plate is covered with a thin layer of flour or sand and is made to vibrate at specific frequencies, so-called standing-wave Chladni patterns appear in which the flour or sand collects along "nodes" (i.e., lines or points that undergo minimal vibration), while areas that undergo the greatest motion (i.e., the "anti nodes") are effectively left empty as the vibration pushes the flour or sand away. Chladni patterns are named after physicist Ernst Chladni who performed the first such experiments in the late 1700s.

I thank my left-brain/day-job as a physicist for introducing me to cymatics in the late 1990s when I stumbled across this paper describing what (at the time, were never before seriously studied) complex emergent patterns in vibrating layers of small granular media (e.g., cylinders filled with BBs from a toy shotgun). One line from this paper immediately grabbed my attention when I first read it and that still haunts me (both as physicist and photographer): "These excitations [called "oscillons"] have a propensity to assemble into 'molecular' and 'crystalline' structures." I remember musing, Whoa!, pump energy into an otherwise static structureless pile of 'things' and get self-organized geometric patterns?!? It was during my (absurdly slow, pre-Google days) search for related experiments that I discovered Jenny's work on cymatics, the underlying dynamics of which has a far-from-superficial overlap with the physics of oscillons.

So, having known about cymatics for about 25 years - and having even posted about it briefly in 2006 on this same blog! - why has it taken me so long to photograph it? I have no easy answer to that, just as I cannot explain why I never photographed my dad-working-as-an-art-restorer when he was still alive, which is something that - 23 years after his passing - I now profoundly regret (see Postscript 1 in this post from 2010). The creative process and the muse that guides our path are both mysterious and ultimately unknowable, which is as it should be. So, I'll leave it at that. But, whatever the reason(s) for my flurry of recent purchases of frequency generators, vertical vibration generators, lights, and more plates, goblets and petri dishes than any sane photographer has reason to own (and our kitchen cupboards have room for), I am - at the moment (and for the foreseeable future) - completely and utterly "obsessed" with cymatics. The reason is simple enough to state: cymatics is a quintessentially perfect amalgam of all three of my aesthetic and intellectual passions - physics, photography, and mysticism

The first two separately play obviously critical roles. The physicist-side of my brain is giddy over the vast phase space waiting to be explored: vibration frequency + medium (type + mix type) + vessel (type + diameter + depth) + ... And the photographer side is not too far behind: light (type + source(s) + directionality) + angle-of-view + f-stop + exposure time + ... But it is the idea of "cymatics as creative bridge" between seen and unseen, between energy and pattern, and between physical and spiritual that I resonate most deeply with, and is most ripe with creative possibilities. (For example, it has not escaped my attention that, in a "mystical" sort of way, the energy that the universe ineffably pumps into an otherwise structureless bag full of 'elemental things' gives rise to an emergent multidimensional dynamic cymatic-like sentient geometry called "Andy")

Since I've only started exploring the cymatics-scape universe, I have no idea what patterns await to be discovered and/or how long the search will keep my interest. But, given that I'm still looking for synesth-scapes after being mesmerized by reflective patterns in my mother-in-law's Nambe-like metal salt and pepper shakers in 2009,  cymatics may take a while 😊

For those still reading this, here is a link to a newly revised version of Hans Jenny's opus, Cymatics: A Study of Wave Phenomenon and Vibration. This version includes both volumes of the original work, as well as new chapters that include a biographical sketch of Hans Jenny, a non-technical primer on the physics of cymatics, and commentaries by researchers, sound therapists, designers, and artists. Indeed, I strongly recommend perusing the entire CymaticSource website, since it is a veritable storehouse of additional information, books and videos. (I am not affiliated with this website in any way. But, having recently purchased the aforementioned reprint of Jenny's revised Cymatics volume, I can personally attest to its quality - it is a stunningly beautiful book.)

Multitudinousness Minds


"Mahamati, since the ignorant and simple-minded, not knowing that the world is only something seen of the mind itself, cling to multitudinousness of external objects, cling to the notions of being and non-being, oneness and otherness, bothness and non-bothness, existence and non-existence, eternity and non-eternity, and think that they have a self-nature of their own, all of which rises from the discriminations of the mind and is perpetuated by habit-energy, and from which they are given over to false imagination. It is all like a mirage in which springs of water are seen as if they were real. "

Near Symmetry of Nature



"So our problem is to explain where symmetry comes from. Why is nature so nearly symmetrical? No one has any idea why. The only thing we might suggest is something like this: There is a gate in Japan, a gate in Neiko, which is sometimes called by the Japanese the most beautiful gate in all Japan; it was built in a time when there was great influence from Chinese art. This gate is very elaborate, with lots of gables and beautiful carving and lots of columns and dragon heads and princes carved into the pillars, and so on. But when one looks closely he sees that in the elaborate and complex design along one of the pillars, one of the small design elements is carved upside down; otherwise the thing is completely symmetrical. If one asks why this is, the story is that it was carved upside down so that the gods will not be jealous of the perfection of man. So they purposely put an error in there, so that the gods would not be jealous and get angry with human beings. We might like to turn the idea around and think that the true explanation of the near symmetry of nature is this: that God made the laws only nearly symmetrical so that we should not be jealous of His perfection!"

Vibration of Quanta


"The quanta of gravity, that is, are not in space; they are themselves space. The spin networks that describe the quantum structure of the gravitational field are not immersed in space, they do not inhabit a space. The location of single quanta of space is not defined with regard to something else, but only by the links, and the relation these express.
...
Space is a spin network whose nodes represent its elementary grains, and whose links describe their proximity relations. Space-time is generated by processes in which these spin networks transform into one another, and these processes are described by sums over spin foams. A spin foam represents a history of a spin network, hence a granular spacetime where the nodes of the graph combine and separate. This microscopic swarming of quanta, which generates space and time, underlies the calm appearance of the macroscopic reality surrounding us. Every cubic centimeter of space, and every second that passes, is the result of this dancing foam of extremely small quanta.
...
In the world described by quantum mechanics there is no reality except in the relations between physical systems. It isn’t things that enter into relations but, rather, relations that ground the notion of ‘thing’. The world of quantum mechanics is not a world of objects: it is a world of events. Things are built by the happening of elementary events: as the philosopher Nelson Goodman wrote in the 1950s, in a beautiful phrase, ‘An object is a monotonous process.’ A stone is a vibration of quanta that maintains its structure for a while, just as a marine wave maintains its identity for a while before melting again into the sea."

Surging and Ebbing


"All mass possesses inertia, all force tends to persist. Owing to this universal property and condition, a body, be it at rest or in motion, tends to remain in the same state, and a force, manifesting itself anywhere and through whatever cause, produces an equivalent opposing force, and as an absolute necessity of this it follows that every movement in nature must be rhythmical. It is borne out in everything we perceive—in the movement of a planet, in the surging and ebbing of the tide, in the reverberations of the air, the swinging of a pendulum, the oscillations of an electric current, and in the infinitely varied phenomena of organic life. Does not the whole of human life attest to it? Birth, growth, old age, and death of an individual, family, race, or nation, what is it all but a rhythm?  All life-manifestation, then, even in its most intricate form, as exemplified in man, however involved and inscrutable, is only a movement, to which the same general laws of movement which govern throughout the physical universe must be applicable."

The Unimaginable Universe


"On the back part of the step, toward the right, I saw a small iridescent sphere of almost unbearable brilliance. At first I thought it was revolving; then I realized that this movement was an illusion created by the dizzying world it bounded. The Aleph’s diameter was probably little more than an inch, but all space was there, actual and undiminished. Each thing (a mirror’s face, let us say) was infinite things, since I distinctly saw it from every angle of the universe. I saw the teeming sea; I saw daybreak and nightfall; I saw the multitudes of America; I saw a silvery cobweb in the center of a black pyramid; I saw a splintered labyrinth (it was London); I saw, close up, unending eyes watching themselves in me as in a mirror; I saw all the mirrors on earth and none of them reflected me; I saw in a back yard of Soler Street the same tiles that thirty years before I’d seen in the entrance of a house in Fray Bentos; I saw bunches of grapes, snow, tobacco, lodes of metal, steam; I saw convex equatorial deserts and each one of their grains of sand...
...
I saw in a closet in Alkmaar a terrestrial globe between two mirrors that multiplied it endlessly; I saw horses with flowing manes on a shore of the Caspian Sea at dawn; I saw the delicate bone structure of a hand; I saw the survivors of a battle sending out picture postcards; I saw in a showcase in Mirzapur a pack of Spanish playing cards; I saw the slanting shadows of ferns on a greenhouse floor; I saw tigers, pistons, bison, tides, and armies; I saw all the ants on the planet...
...
I saw a Persian astrolabe; ... I saw the rotted dust and bones ... I saw the circulation of my own dark blood; ... I saw the Aleph from every point and angle, and in the Aleph I saw the earth and in the earth the Aleph and in the Aleph the earth; I saw my own face and my own bowels; I saw your face; and I felt dizzy and wept, for my eyes had seen that secret and conjectured object whose name is common to all men but which no man has looked upon — the unimaginable universe."

Zen Compositions


"The harder we try to catch hold of the moment, to seize a pleasant sensation..., the more elusive it becomes... It is like trying to clutch water in one's hands - the harder one grips, the faster it slips through one's fingers.
...
But you cannot understand life and its mysteries as long as you try to grasp it. Indeed, you cannot grasp it, just as you cannot walk off with a river in a bucket. If you try to capture running water in a bucket, it is clear that you do not understand it and that you will always be disappointed, for in the bucket the water does not run. To “have” running water you must let go of it and let it run.
...
Trying not to grasp is the same thing as to grasp since it's motivation is the same, my urgent desire to save my self from a difficulty. I can not get rid of this desire since it is one and the same desire as the desire to get rid of it."

Alan Watts (1915 - 1973)

Postscript. My last post explained what my recent series of "autumnal abstracts" has to do with quantum mechanics. This post is meant to convey the complementary explanation of what my autumnal abstracts have to do with Zen. Leaving aside the unintentional recursivity of the word "complementary" (since the concept has a formal meaning in quantum mechanics), here is an alternative summary of how using knee-high waterproof boots to get "up close and personal" to patterns of leaves in the creek - ostensibly to get better compositions - failed miserably. As I explained in the last post, no matter how slowly I approached a clump of leaves, invariably, the ripples induced in the water by my boots would dislodge one or more of the key elements of whatever composition I saw in my mind's eye. By the time I stood over the spot where I saw the original pattern, most of the leaves were gone. Here is where the Zen side of story begins...

The first day I donned my boots, it took me about a dozen attempts to learn how to "minimally disturb" whatever it was that caught my eye; to emphasize, not one, two or a few tries, but an embarrassingly many attempts. It was vastly harder than I anticipated. At some point - after my 3rd or 4th failure - I dejectedly poked my tripod into the water, angry with myself at being unable to do such a "simple” thing. So there I stood, knee-deep in water, immersed in a euphonious Siren call of delicately beautiful patterns I so wished to capture but which vanished the instant I approached them, when the absurdity of it all finally struck me like a Zen-master's cane! I doubled over with laughter, as multiple versions of Alan Watt's "the harder we try to catch hold of the moment..." aphorisms leapt to mind.

Adding to this genuinely Zen-like moment was the fact that two joggers just happened to be close enough to see and hear me. They both turned in unison to see what the source of the absurd laughter was. Without breaking stride or uttering a word, they just stared at what from their perspective must have seemed a "not quite all there and possibly drunk photographer" and ran off into the woods. I laughed for a few more moments, resolved to remember this little creek's Zen lesson, and resumed searching for interesting and evanescent patterns.

So, are my (still ongoing) "autumnal abstracts" a lesson in quantum mechanics? in Zen? or something else entirely? In the end, it's all just a matter of perspective 😊

Quantum Compositions


"Science no longer is in the position of observer of nature, but rather recognizes itself as part of the interplay between man and nature. The scientific method ... changes and transforms its object: the procedure can no longer keep its distance from the object ... Every experiment destroys some of the knowledge of the system which was obtained by previous experiments.
...
Our scientific work in physics consists in asking questions about nature in the language that we possess and trying to get an answer from experiment by the means at our disposal. In this way quantum theory reminds us, as Bohr has put it, of the old wisdom that when searching for harmony in life one must never forget that in the drama of existence we are ourselves both players and spectators. It is understandable that in our scientific relation to nature our own activity becomes very important when we have to deal with parts of nature into which we can penetrate only by using the most elaborate tools.
...
Since the measuring device has been constructed by the observer … we have to remember that what we observe is not nature itself but nature exposed to our method of questioning. Our scientific work in physics consists in asking questions about nature in the language that we possess and trying to get an answer from experiment by the means that are at our disposal."

Werner Heisenberg (1901 - 1976)

Postscript. At the end of my last post, I promised to explain what my recent series of "autumnal abstracts" (which I started in mid September) has to do with quantum mechanics (yes, quantum mechanics). The simplest explanation (sure to induce a mild groan in readers) is that since my left-brain "day job" is anchored on my being a physicist, physics in general, and quantum mechanics in particular, is never far from my thoughts 😉 But no, that's not the full explanation. The real connection is part whimsy and part serious (the serious part is expertly summarized by one of the founding fathers of quantum mechanics, Heisenberg, above). As I explained in my previous post, I've recently been "rewarding" myself after long work days by driving to a local trail that runs along a shallow leaf-strewn creek, and spend however much time remains before the sun goes down searching for intimate compositions of leaves, rocks, and reflections within the water.

For my first few outings, I had no issues. I would park myself on the little bridge I need to cross to get to the trail from where I leave my car, set up a tripod, and use a telephoto zoom to isolate patterns of interest. Here is a taste of what I see from the bridge:


Of course, I didn't limit myself to just standing on the bridge. I prowled around the area surrounding the bridge, and explored different perspectives made accessible by positioning myself somewhere along the left and right banks of the creek. And, indeed, in this way, I usually walked away with at least few decent keepers. But I also noticed that the best compositions (at least in my mind's eye) were always just beyond my reach. I needed to get into the water! And that's where quantum mechanics comes in ...

The solution was simple enough. I put on a pair of knee-high waterproof boots, tucked in my pants, grabbed a waterproof (well, water resistant) tripod, and started composing "up close and personal" in the water; or so I thought. I immediately ran into an unexpected "quantum mechanics"-like problem: after seeing some pattern of interest (say, some combination of leaves, rocks and reflections), I would naturally walk over to get a better look and see where to best anchor my tripod. But no matter how slowly I approached, invariably, the ripples induced in the water by my boots would dislodge one or more of the key elements of whatever pattern caught my eye. By the time I got to the original composition, the pattern was either gone and/or replaced by another only less than half as good. This happened over and over again, no matter how slowly - ever, so slooooowly - I walked toward some entangled leaves. A text-book (albeit, whimsical) example of the well-known, but no less mysterious, quantum mechanical "observer effect." The analogy actually runs a bit deeper: while observer-induced perturbations also happen in "classical" physics, the difference is that quantum mechanics does not allow the observer to reconstruct what the "true state of the system" was after observing it; the act of observing the state irretrievably scrambles it. Just as, in my case, "seeing and moving toward a" pattern of leaves irretrievably destroys it. (BTW, at the risk of overloading most readers of a photography blog, it is worth mentioning that entanglement - a subtle nod to which appeared in the phrase "entangled leaves" - is another inherently quantum behavior that is best left for a future post) 😊

Subjective Feels


"Supporters of strong emergent materialism point to the fundamental differences between the subjective psychological reality and the objective physical (or neural) reality. The former includes qualitative experiences that feel like something and exist only from the first-person point of view; the latter consists of physical entities and causal mechanisms that involve nothing subjective or qualitative about them and exist from the third-person point of view or objectively. Nothing we can think about or imagine could make an objective physical process turn into or 'secrete' subjective, qualitative 'feels.' It is like trying to squeeze wine out of pure water: it is just not there, and there can be no natural mechanism (short of magic) that could ever turn the former into the latter."

Patterns of Organic Energy


"'Wu Li' was more than poetic. It was the best definition of physics that the conference would produce. It caught that certain something, that living quality that we were seeking to express in a book, that thing without which physics becomes sterile. 'Wu' can mean either 'matter' or 'energy.' 'Li' is a richly poetic word. It means 'universal order' or 'universal law.' It also means 'organic patterns.' The grain in a panel of wood is Li. The organic pattern on the surface of a leaf is also Li, and so is the texture of a rose petal. In short, Wu Li, the Chinese word for physics, means 'patterns of organic energy' ('matter/ energy' [Wu] + 'universal order/organic patterns' [Li]). This is remarkable since it reflects a world view which the founders of western science (Galileo and Newton) simply did not comprehend, but toward which virtually every physical theory of import in the twentieth century is pointing!"

Ontology of Materialism


"What we observe is not nature itself, but
nature exposed to our method of questioning.
...
The ontology of materialism rested upon
the illusion that the kind of existence,
the direct 'actuality' of the world around us,
can be extrapolated into the atomic range.
This extrapolation, however, is impossible...
Atoms are not things.
...
Whenever we proceed from the known into the unknown
we may hope to understand, but we may have to learn
at the same time a new meaning
of the word 'understanding."

String Theory


"For me, the most beautiful aspects of physics are not the complicated math equations or even the ability of predicting how things will happen. What attracts me to physics is what it teaches us about the bigger picture. The general philosophical lessons that are embedded in physical laws are what excite me. For example, the fact that all particles and forces get unified within string theory teaches us about the unity underlying our universe. The amazingly vast collection of solutions to equations of string theory suggests that there may be many universes besides ours. What happened before the big bang, or was there a time before big bang? The 'duality symmetry' in string theory, which exchanges small spaces with large spaces, suggests that perhaps as we go back in time the universe was effectively getting bigger instead of smaller. This suggests we came from other universes. Physics teaches us deep facts about our universe and our place in it. I hope I can add a little to this beautiful story. That is my goal."

Psycho-Physical Events


"Reality, according to Heisenberg, is built not out of matter, as matter was conceived of in classical physics, but out of psycho-physical events – events with certain aspects that are described in the language of psychology and with other aspects that are described in the mathematical language of physics – and out of objective tendencies for such events to occur. ‘The probability function…represents a tendency for events and our knowledge of events’  ... The deepest human intuition is not the immediate grasping of the classical-physics-type character of the external world. It is rather that one's own conscious subjective efforts can influence the experiences that follow. Any conception of nature that makes this deep intuition an illusion is counterintuitive. Any conception of reality that cannot explain how our conscious efforts influence our bodily actions is problematic. What is actually deeply intuitive is the continually reconfirmed fact that our conscious efforts can influence certain kinds of experiential feedback. A putatively rational scientific theory needs at the very least to explain this connection in a rational way to be in line with intuition."

Hidden Reality


"'It is a mystery to me,' he told me, 'why we have quantum mechanics when there is only one state of the universe.' In other words, why should there be probabilities of alternative conditions of our universes when we inhabit only one condition? And do those other potential conditions actually exist in other universes somewhere?
...
Some people believe that there is no distinction between the spiritual and physical universes, no distinction between the inner and the outer, between the subjective and the objective, between the miraculous and the rational. I need such distinctions to make sense of my spiritual and scientific lives. For me, there is room for both a spiritual universe and a physical universe, just as there is room for both religion and science. Each universe has its own power. Each has its own beauty, and mystery.
...
Since Foucault, more and more of what we know about the universe is undetected and undetectable by our bodies. What we see with our eyes, what we hear with our ears, what we feel with our fingertips, is only a tiny sliver of reality. Little by little, using artificial devices, we have uncovered a hidden reality. It is often a reality that violates common sense. It is often a reality strange to our bodies. It is a reality that forces us to re-examine our most basic concepts of how the world works. And it is a reality that discounts the present moment and our immediate experience of the world."

Qualitative Forms


"We have written the equations of water flow. From experiment, we find a set of concepts and approximations to use to discuss the solution - vortex streets, turbulent wakes, boundary layers. When we have similar equations in a less familiar situation, and one for which we cannot yet experiment, we try to solve the equations in a primitive, halting, and confused way to try to determine what new qualitative features may come out, or what new qualitative forms are a consequence of the equations. Our equations for the sun, for example, as a ball of hydrogen gas, describe a sun without sunspots, without the rice-grain structure of the surface, without prominences, without coronas. Yet, all of these are really in the equations; we just haven't found the way to get them out.
...
The next great era of awakening of human intellect may well produce a method of understanding the qualitative content of equations. Today we cannot. Today we cannot see that the water flow equations contain such things as the barber pole structure of turbulence that one sees between rotating cylinders. Today we cannot see whether Schrodinger's equation contains frogs, musical composers, or morality - or whether it does not.
...
