Vibrating Universe


"Gravitational waves are fundamentally different. Not only is a gravitational wave a side-to-side, lateral wave like light, not a longitudinal wave like sound, but it isn’t a ripple through objects in spacetime; it passes through spacetime itself. When a gravitational wave passes by, spacetime squeezes and contracts. This oscillation influences matter, which exists in spacetime – but doesn’t require matter to be able to travel. It’s quite demeaning to gravitational waves to call their detection ‘hearing the sound of black holes in space’ as some have done. By comparison, sound is a trivial local effect. Gravitational waves make the universe itself vibrate."

Paradoxes and Contradictions


"We can pull atoms apart, peer back at the first light and predict the end of the universe with just a handful of equations, squiggly lines and arcane symbols that normal people cannot fathom, even though they hold sway over their lives. But it's not just regular folks; even scientists no longer comprehend the world. Take quantum mechanics, the crown jewel of our species, the most accurate, far-ranging and beautiful of all our physical theories. It lies behind the supremacy of our smartphones, behind the Internet, behind the coming promise of godlike computing power. It has completely reshaped our world. We know how to use it, it works as if by some strange miracle, and yet there is not a human soul, alive or dead, who actually gets it. The mind cannot come to grips with its paradoxes and contradictions. It's as if the theory had fallen to earth from another planet, and we simply scamper around it like apes, toying and playing with it, but with no true understanding."

Dissolved Into The Picture


"I have for many years searched for the possibility of letting the viewer 'stroll' in the picture, forcing him to forget himself and dissolve into the picture.
...
A frightening depth of questions, weighted with responsibility, confronted me. And the most important: what should replace the missing object? The danger of ornamentation was clear, the dead make-believe existence of stylized forms could only frighten me away.
...
It took a very long time before this question (What should replace the object?) received a proper answer from within me. Often I look back into my past and am desolate to think how much time I took for the solution. I have only one consolation: I could never bring myself to use a form which developed out of the application of logic—not purely from feeling within me. I could not think up forms, and it repels me when I see such forms. All the forms which I ever used came “from themselves,” they presented themselves complete before my eyes, and it only remained for me to copy them, or they created themselves while I was working, often surprising me. "

Esse Est Percipi


"...neither our thoughts, nor passions, nor ideas formed by the imagination, exist without the mind, is what everybody will allow. And to me it is no less evident that the various sensations or ideas imprinted on the sense, however blended or combined together (that is, whatever objects they compose) , cannot exist otherwise than in a mind perceiving them … The table I write on I say exists, that is, I see and feel it; and if I were out of my study I should say it existed-meaning thereby that if I was in my study I might perceive it, or that some other spirit actually does perceive it ... or as to what is said of the absolute existence of unthinking things without any relation to their being perceived, that is to me perfectly unintelligible. Their esse is percipi, nor is it possible they should have any existence out of the minds or thinking things which perceive them. [Berkeley, The Principles of Human Knowledge, quoted by JLB]
...
With the continuities of matter and spirit denied,
with space denied, I do not know by what
right we retain that continuity which is time.
Outside each perception (real or conjectural),
matter does not exist;
outside each mental state,
spirit does not exist;
neither then must time exist
outside each present moment.

...
[We] are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity ... The mind is a kind of theater, where several perceptions successively make their appearance; pass, repass, glide away, and mingle in an infinite variety of postures and situations ... The comparison of the theater must not mislead us. They are the successive perceptions only, that constitute the mind; nor have we the most distant notion of the place, where these scenes are represented, or of the materials of which it is composed. [Hume, A Treatise of Human Nature, quoted by JLB]"

Time and Space

"Because of the hazy, nondefinite character of quantum physics (called the Heisenberg uncertainty principle), at the dimensions of the Planck length, space and time churn and seethe, with the distance between any two points wildly fluctuating from moment to moment, and time randomly speeding and slowing, perhaps even going backward and forward. In such a situation, time and space no longer exist in a way that has meaning to us."

A Dizzying Trance Sublime and Strange


"The everlasting universe of things
Flows through the mind, and rolls its rapid waves,
Now dark—now glittering—now reflecting gloom—
Now lending splendour, where from secret springs
The source of human thought its tribute brings
Of waters,—with a sound but half its own,
Such as a feeble brook will oft assume
In the wild woods, among the mountains lone,
Where waterfalls around it leap for ever,
Where woods and winds contend, and a vast river
Over its rocks ceaselessly bursts and raves.
...
Thou art pervaded with that ceaseless motion
Thou art the path of that unresting sound—
Dizzy Ravine! And when I gaze on thee
I seem as in a trance sublime and strange
To muse on my own separate fantast,
My own, my human mind, which passively
Now renders and receives fast influencings,
Holding an unremitting interchange
With the clear universe of things around;"

- Percy Bysshe Shelley (1792 - 1822)
Mont Blanc: Lines Written in the Vale of Chamouni

The word "dizzy," when used as a verb, means "to make giddy"; and giddy, in turn, is "an adjective that describes a feeling of dizziness or lightheadedness. It can also refer to a feeling of excitement or euphoria that causes a person to feel unsteady or unstable. Giddy can be used to describe physical sensations, emotional states, or even situations that are overwhelming or disorienting [ref]." It is with these nuanced interpretations that the words "dizzy" and "giddy" often popped into my mind during our trip to Iceland, which is filled with dizzying landscapes that evoke giddy awe. As some of my earlier images from our recent trip have already hinted, Iceland is replete with dissonant scales of time and space. Distant mountains are just as likely to appear as illusory nearby foothills, as nearby crags are to easily fool you into believing they are remotely distant. (Neither of which may even be true, as Borges might have once said in some other world.) Iceland's landscapes tend to induce trance-like states of "giddy anxiety" - unabashed awe, really - unless, and until, visitors somehow find a way to calibrate Iceland's a priori incommensurate scales of time and distance. 

The image above conveys a bit of this mysterious tension. Look at the picture but first use a finger to block out the small cluster of white buildings in the lower right. The remaining part of the image appears to be a "landscape" like any other, with a trace of a distant (but otherwise “normal”) mountain range. Now, remove your finger and let your eyes absorb the complete scene. Assuming your reaction is in any way like mine, you will experience a sense of "dizzying vertigo" as your brain's visual cortex tries desperately to make sense of the dissonant scales of size and distance; and leaves you grappling with the absurdity of the mountains having instantly grown tenfold in height! I lost count of the number of times I felt this way looking at Iceland's landscapes through my camera's viewfinder.

The Original Mystery


"Let us consider, for a moment, the world as described by the physicist. It consists of a number of fundamental particles which, if shot through their own space, appear as waves, and are thus… of the same laminated structure as pearls or onions, and other wave forms called electromagnetic which it is convenient, by Occam’s razor, to consider as travelling through space with a standard velocity. All these appear bound by certain natural laws which indicate the form of their relationship.

Now the physicist himself, who describes all this, is, in his own account, himself constructed of it. He is, in short, made of a conglomeration of the very particulars he describes, no more, no less, bound together by and obeying such general laws as he himself has managed to find and to record. 

Thus we cannot escape the fact that the world we know is constructed in order (and thus in such a way as to be able) to see itself. This is indeed amazing. Not so much in view of what it sees, although this may appear fantastic enough, but in respect of the fact that it can see at all.
 
But in order to do so, evidently it must first cut itself up into at least one state which sees, and at least one other state which is seen. In this severed and mutilated condition, whatever it sees is only partially itself. We may take it that the world undoubtedly is itself (i. e. is indistinct from itself), but, in any attempt to see itself as an object, it must, equally undoubtedly, act so as to make itself distinct from, and therefore false to, itself. In this condition it will always partially elude itself

It seems hard to find an acceptable answer to the question of how or why the world conceives a desire, and discovers an ability, to see itself, and appears to suffer the process. That it does so is sometimes called the original mystery. Perhaps, in view of the form in which we presently take ourselves to exist, the mystery arises from our insistence on framing a question where there is, in reality, nothing to question.
...
Thus the world, whenever it appears as a physical universe*, must always seem to us, its representatives, to be playing a kind of hide-and-seek with itself. What is revealed will be concealed, but what is concealed will again be revealed.

* unus = one, vertere = turn. Any given (or captivated) universe is what is seen as the result of a making of one turn, and thus is the appearance of any first distinction, and only a minor aspect of all being, apparent and non-apparent. Its particularity is the price wo pay for its visibility."

Limited Piece of the Whole


"A human being is a spatially and
temporally limited piece of the whole,
what we call the 'Universe.'
He experiences himself and his
feelings as separate from the rest,
an optical illusion of his consciousness.
The quest for liberation from this bondage
[or illusion] is the only object of true religion.
Not nurturing the illusion but only overcoming
it gives us the attainable measure of inner peace."

Little Ripples

 

"The waves of the sea, the little ripples on the shore, the sweeping curve of the sandy bay between the headlands, the outline of the hills, the shape of the clouds, all these are so many riddles of form, so many problems of morphology.
...
Our own study of organic form, which we call by Goethe's name of Morphology, is but a portion of that wider still Science of Form which deals with the forms assumed by matter under all aspects and conditions, and, in a still wider sense, with forms which are theoretically imaginable.
...
We rise from the conception of form to an understanding of the forces which gave rise to it... in the representation of form we see a diagram of forces in equilibrium, and in the comparison of kindred forms we discern the magnitude and the direction of the forces which have sufficed to convert the one form into the other.
...
We have come to the
edge of a world of which
we have no experience, and
where all our preconceptions
must be recast."

Known and the Unknown


"Reality for me is the known, it is of sense-brain-mind. Existence is the unknown, for no one has created any existence. I experience reality. I believe in existence. Its signals of light and sound as well as all its other signals assail my senses. I don’t know what light or any of the other signals are except that they are manifestations of existence. If I photograph in such a way that I meaningfully evoke a sense of the known and the unknown, I feel I have succeeded."

Wynn Bullock (1902 - 1975)

Postscript. This diptych contains far too many "meanings" and associations than I can possibly make explicit using mere words. And yet, apart from images and words (as accompanied by omnipresent sounds, smells, tastes, and feelings & intuitions), what is our "world" if not an ever-churning ineffable broth of shared-but-solitary experiences that we wish to communicate some vestiges of to others? This past week, my wife and I had the honor and privilege of settling our youngest child (Josh) into college. It was simultaneously a most joyous and beguilingly melancholy affair, as all parents with college-age offspring know all-too-well. The images in the diptych above were taken a day after we waved to Josh one last time during our "settling-him-in visit" as he headed off to his dorm, at a beach not too far from his college. I was drawn to the fleeting patterns of sand and weeds as they self-organized by the gentle lapping of the waves, only to disassemble and re-organize into myriad other related shapes and geometries as each new wave rolled in. What are we if not conscious bits of "sand and weeds" trying to retain (and understand?) our own transient patterns in the vast - and vastly unknown - phantasmagoric "reality" we call life? What future manifestations of the "pattern" we now call "Josh" will the "waves" of life sculpt in future times? And so, here are some loose associations that this diptych will for me henceforth always be accompanied by whenever my eyes gaze upon it: rhythms (of waves, of winds, and life's energies); ephemerality; yin/yang; known & unknown; memories, longing, and anticipations; the simultaneity of past, present, and future; and - simply and irreducibly - a bird leaves its nest as Josh goes away to college.

The Behavior of Things


"Electrons, when they were first discovered, behaved exactly like particles or bullets, very simply. Further research showed, from electron diffraction experiments for example, that they behaved like waves. As time went on there was a growing confusion about how these things really behaved ---- waves or particles, particles or waves? Everything looked like both.

This growing confusion was resolved in 1925 or 1926 with the advent of the correct equations for quantum mechanics. Now we know how the electrons and light behave. But what can I call it? If I say they behave like particles I give the wrong impression; also if I say they behave like waves. They behave in their own inimitable way, which technically could be called a quantum mechanical way. They behave in a way that is like nothing that you have seen before. Your experience with things that you have seen before is incomplete. The behavior of things on a very tiny scale is simply different. An atom does not behave like a weight hanging on a spring and oscillating. Nor does it behave like a miniature representation of the solar system with little planets going around in orbits. Nor does it appear to be somewhat like a cloud or fog of some sort surrounding the nucleus. It behaves like nothing you have seen before.

There is one simplification at least. Electrons behave in this respect in exactly the same way as photons; they are both screwy, but in exactly in the same way….

The difficulty really is psychological and exists in the perpetual torment that results from your saying to yourself, "But how can it be like that?" which is a reflection of uncontrolled but utterly vain desire to see it in terms of something familiar. I will not describe it in terms of an analogy with something familiar; I will simply describe it. There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time. There might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot of people understood the theory of relativity in some way or other, certainly more than twelve. On the other hand, I think I can safely say that nobody understands quantum mechanics. So do not take the lecture too seriously, feeling that you really have to understand in terms of some model what I am going to describe, but just relax and enjoy it. I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this, you will find her a delightful, entrancing thing. Do not keep saying to yourself, if you can possible avoid it, "But how can it be like that?" because you will get 'down the drain', into a blind alley from which nobody has escaped. Nobody knows how it can be like that."

Radiance and Instability


"Current-borne, wave-flung, tugged hugely by the whole might of ocean, the jellyfish drifts in the tidal abyss. The light shines through it, and the dark enters it. Borne, flung, tugged from anywhere to anywhere, for in the deep sea there is no compass but nearer and farther, higher and lower, the jellyfish hangs and sways; pulses move slight and quick within it, as the vast diurnal pulses beat in the moondriven sea. Hanging, swaying, pulsing, the most vulnerable and insubstantial creature, it has for its defense the violence and power of the whole ocean, to which it has entrusted its being, its going, and its will.

But here rise the stubborn continents. The shelves of gravel and the cliffs of rock break from water baldly into air, that dry, terrible outerspace of radiance and instability, where there is no support for life. And now, now the currents mislead and the waves betray, breaking their endless circle, to leap up in loud foam against rock and air, breaking....

What will the creature made all of seadrift do on the dry sand of daylight; what will the mind do, each morning, waking?"

- Ursula K. Le Guin (1929 - 2018)

Quantum Objects


"Quantum objects present us with a choice of languages, but it’s too easily forgotten that this is precisely what it is: a struggle to formulate the right words, not a description of the reality behind them. Quantum objects are not sometimes particles and sometimes waves, like a football fan changing her team allegiance according to last week’s results. Quantum objects are what they are, and we have no reason to suppose that ‘what they are’ changes in any meaningful way depending on how we try to look at them. Rather, all we can say is that what we measure sometimes looks like what we would expect to see if we were measuring discrete little ball-like entities, while in other experiments it looks like the behavior expected of waves of the same kind as those of sound travelling in air, or that wrinkle and swell on the sea surface. So the phrase ‘wave–particle duality’ doesn’t really refer to quantum objects at all, but to the interpretation of experiments – which is to say, to our human-scale view of things."

Ripples


"The surface of the quieted river, as I think now, is like a window looking into another world that is like this one except that it is quiet. Its quietness makes it seem perfect. The ripples are like the slates of a blind of a shutter through which we see imperfectly what is perfect. Though that other world can be seen only momentarily, it looks everlasting. As the ripples become more agitated, the window darkens and the other world is hidden.the surface of the river is like a living soul, which is easy to disturb, is often disturbed, but, growing calm, shows what it was, is, and will be."

- Wendell Berry (1934 - )

A Participatory Universe


"Spacetime in the prequantum dispensation was a great record parchment. This sheet, this continuum, this carrier of all that is, was and shall be, had its definite structure with its curves, waves and ripples; and on this great page every event, like a glued down grain of sand, had its determinate place. In this frozen picture a far-reaching modification is forced by the quantum. What we have the right to say of past spacetime, and past events, is decided by choices – of what measurements to carry out – made in the near past and now. The phenomena called into being by these decisions reach backward in time in their consequences ... back even to the earliest days of the universe. Registering equipment operating in the here and now has an undeniable part in bringing about that which appears to have happened. Useful as it is under everyday circumstances to say that the world exists “out there” independent of us, that view can no longer be upheld. There is a strange sense in which this is a 'participatory universe'."

Deep Infinity


“Deep, deep infinity! 

Quietness. 

O dream away from the 
tensions of daily living; 
to sail over a calm sea at 
the prow of a ship,
toward a horizon that always recedes;
to stare at the passing waves and listen to
their monotonous soft murmur;
to dream away into unconsciousness ..."

- M.C. Escher (1898-1972)

Ripples, Waves, and Rhythms


"To Nature nothing can be added; from Nature nothing can be taken away; the sum of her energies is constant, and the utmost man can do in the pursuit of physical truth, or in the applications of physical knowledge, is to shift the constituents of the never-varying total. The law of conservation rigidly excludes both creation and annihilation. Waves may change to ripples, and ripples to waves; magnitude may be substituted for number, and number for magnitude; asteroids may aggregate to suns, suns may resolve themselves into florae and faunae, and floras and faunas melt in air: the flux of power is eternally the same. It rolls in music through the ages, and all terrestrial energy—the manifestations of life as well as the display of phenomena—are but the modulations of its rhythm."

(1820 - 1893)

Undulating Shadows


"There is, one knows not what sweet mystery about his sea, whose gently awful stirrings seem to speak of some hidden soul beneath; like those fabled undulations of the Ephesian sod over the buried Evangelist St. John.  And meet it is, that over these sea-pastures, wide rolling watery prairies and Potters’ Fields of all four continents, the waves should rise and fall, and ebb and flow unceasingly; for here, millions of mixed shades and shadows, drowned dreams, dreaming still; tossing like slumberers in their beds; the ever-rolling waves but made so by their restlessness." - Herman Melville, Moby Dick

Rhythmic Waves

"The same stream of life that runs through my veins night and day runs through the world and dances in rhythmic measures. It is the same life that shoots in joy through the dust of the earth in numberless blades of grass and breaks into tumultuous waves of leaves and flowers. It is the same life that is rocked in the ocean-cradle of birth and of death, in ebb and in flow. I feel my limbs are made glorious by the touch of this world of life. And my pride is from the life-throb of ages dancing in my blood this moment." - Rabindranath Tagore (1861 - 1941)

Transcendental Mirrors


"Bodies of still water are
themselves like minds;
transcendental mirrors, 
Platonic cameras
to catch and hold 
the phenomenological long enough 
for the onlooker to grasp its reality,
the eternal thing behind it."

- David Mason Greene

"There is, one knows not what sweet mystery about his sea, whose gently awful stirrings seem to speak of some hidden soul beneath; like those fabled undulations of the Ephesian sod over the buried Evangelist St. John.
