Entanglement



"Indeed, it is the quantum entanglement between the 'object' and the 'agencies of observation,' in this case, between the atom and the apparatus that is precisely what we need to attend to in making the interference pattern evident. Once again we see evidence for the ontological priority of phenomena over objects. If one focuses on abstract individual entities the result is an utter mystery, we cannot account for the seemingly impossible behavior of the atoms. It’s not that the experimenter changes a past that had already been present or that atoms fall in line with a new future simply by erasing information. The point is that the past was never simply there to begin with and the future is not simply what will unfold; the 'past' and the 'future' are iteratively reworked and enfolded through the iterative practices of spacetimemattering—including the which-slit detection and the subsequent erasure of which-slit information—all are one phenomenon."

Collective Field


"Intelligence ... is not something to be tested, but something to be recognized, in all the multiple forms that it takes. The task is to figure out how to become aware of it, to associate with it, to make it manifest. This process is itself one of entanglement, of opening ourselves to forms of communication and interaction with the totality of the more-than-human world, much deeper and more extensive than those which can be performed in the artificial constraints of the laboratory. It involves changing ourselves, and our own attitudes and behaviors, rather than altering the conditions of our non-human communicants.
...
Each thing organizes the space around it, rebuffing or sidling up against other things; each thing calls, gestures, beckons to other beings or battles them for our attention; things expose themselves to the sun or retreat among the shadows, shouting with their loud colors or whispering with their seeds; rocks snag lichen spores from the air and shelter spiders under their flanks; clouds converse with the fathomless blue and metamorphose into one another; they spill rain upon the land, which gathers in rivulets and carves out canyons.
...
The 'real world' in which we find ourselves, then—the very world our sciences strive to fathom—is not a sheer 'object,' not a fixed and finished 'datum' from which all subjects and subjective qualities could be pared away, but is rather an intertwined matrix of sensations and perceptions, a collective field of experience lived through from many different angles. The mutual inscription of others in my experience, and (as I must assume) of myself in their experiences, effects the interweaving of our individual phenomenal fields into a single, ever-shifting fabric, a single phenomenal world or 'reality.'"

Mathematical Beauty


"The harmony of the
world is made manifest
in Form and Number,
and the heart and soul
and all the poetry of
Natural Philosophy are
embodied in the concept
of mathematical beauty."

- D'Arcy Wentworth Thompson (1860 - 1948)

Postscript. As may be the case with many of you, my day-job constraints leave me precious little time to devote to purely aesthetic pleasures (notwithstanding those that occasionally overlap with more mathematical pursuits). Sometimes, as now, even my weekend time is filled mostly with staring at gibberish on a computer screen, and pounding away at my keyboard to produce picture-less reams of technical reports (even as I day-dream of month-long photo-safaris in far-away lands). Thus, the short walks my wife and I take through our neighborhood after breakfast each day have become immeasurably important physical and spiritual oases for me. The simple pleasure of encountering beautifully haphazard arrangements of natural forms rejuvenates and nourishes my soul. The images in the triptych above were taken no more than a few minutes apart during a walk that itself lasted less than a half hour. But what a joy it is to stumble upon such humble transcendent beauty hiding in plain sight! The great polymath Thompson's book, On Growth and Form (the first edition of which came out in 1917, and which to this day remains an extraordinarily beautiful book to read) is essentially a 1100+ page erudite argument that biology can be reduced to mathematics (a sentiment that a much younger version of myself would have been happy to accept): "It behooves us always to remember that in physics it has taken great men to discover simple things. They are very great names indeed which we couple with the explanation of the path of a stone, the droop of a chain, the tints of a bubble, the shadows in a cup. It is but the slightest adumbration of a dynamical morphology that we can hope to have until the physicist and the mathematician shall have made these problems of ours their own." For those of you interested in exploring (taking a deep-dive, really, into) the broader entanglement of art and science, here are some slides I used for a 2017 presentation at a Humanities and Technology Association conference (held that year in Newport, RI). This lecture is one of three I've given in (relatively) recent years during which I wore both of my hats, as physicist and photographer. The other two lectures were given at the American Center for Physics (College Park, MD in 2009) and at the Morrison House (Alexandria, VA in 2011).
