IntroductionTJust as a quantum particle has both a virtual and a physical dimension, so does a work of digital art, which exists as both invisible code and visual display. The dual nature of matter in quantum mechanics is mirrored by the dual nature of a work of digital art. Just as a photon is both a particle and a wave, a work of digital art is both a set of

instructions and the execution of those instructions. Digital art, software art, or any work of art that utilizes media as its medium- is both a set of structural relations (a system of process) and a set of discrete objects in space. This is conceptual dualism rather than physical dualism. But how does one make sense of diametriclly opposite models of the same thing without suffering a bit of cognitive dissonance? Neil’s Bohr, one of the father’s of quantum mechanics, points the way out: embrace the paradox.

2.0 The Paradoxical Nature of Matter and Complementarity

The infamous “double slit experiment” shows that when a beam of light, composed of individual photons, passes through two slits cut through a screen it produces a wave like interference pattern on a second distant screen. These interference patterns are identical to those produced by waves as they lap over each other. But that is impossible given our classical understanding of an individual particle. The ontology of individuality says that no two particles can occupy the same point in space and time. The fundamental point/mass of classical physics is a hard irreducible “thing” that occupies space and moves through time. According to the classical physics the observed
interference in the two-slit experiment is the result of some atoms going through one slit and some going through the others, resulting in collisions when they meet again at the screen.

.

The “double slit experiment” has another surprise in store. If we modify the light source and shoot one photon at time at the double slits, we will still see the exact same wave like interference pattern on the distant screen. But for this to be possible each photon would have to pass through both slits. Clearly this is impossible if we believe subatomic particles to be “objects” with distinct physical properties.

As if that weren’t strange enough, if you try to determine which slit the photon passes through the wave
pattern disappears. The detector interacts physically with the photon, such that its position becomes fixed. The wave of probability disappears and is replaced by the registration of a single particle. The quantum world violates our expectations at every turn. Our classical logic, which separates the world into binary categories of “either/or” stumbles when we encounter quantum phenomenon, which stubbornly resists being, pinned down.

An electron can be reduced to a fixed mass point in space: a particle; or a field of probability- the quantum wave function. These alternate states of being are mutually exclusive yet equally valid, depending on oneʼs frame of reference. Our frame of reference, which includes our position, momentum, and choice of measurement
apparatus, must be included in any description of a sub-atomic particle. No single frame of reference is capable of a “complete description” because other perspectives have an equal claim on the “truth”, hence we have electrons behaving in contrary fashion- either particle or wave-depending upon the scale of our observation. We
cannot exhaust the ontological possibilities of the “thing” being described

Niels Bohr, paradox and complementarity

Unable to square the circle of contrary atomic description, physicist Neils Bohr proposed something radical: embrace the paradox. Bohr proposed the notion of Complementarity in order to deal with the cognitive dissonance caused by the paradoxical nature of matter.

Complementarity tells us we can hold two simultaneously contradictory descriptions about the same phenomenon by acknowledging their mutually exclusive contexts. Columbian physicist Jairo Roldan describes the elusive notion of complementarity this way: “Two experiences or phenomena will be complementary if they are mutually excluding and they have the same quantum object” [1]. The conceptual dualism of complementarity applies directly to the behavior of electrons.

According to physicist Paul Davies: From the quantum angle, an electron is not simply an electron. Shifting energy patterns shimmer around it, financing the unpredictable appearance of photons, protons, mesons, and even other electrons. In short all the paraphernalia of the subatomic world latches on to an electron like an intangible, evanescent cloak, a shroud of ghostly bees swarming around the central hive.

Davies describes the electron as a complex system rather than a point mass in space as Newtonian mechanics might have us believe. Nevertheless, Newton’s mechanical principles are in fact just as correct, only they have a limited frame of reference. From within the classical world electrons are best treated as individual particles. This is
Newton’s world. But from the sub-atomic perspective of quantum mechanics, electrons dissolve into fields.

All matter, as it turns out, has a dual nature: both particle and wave, depending upon how we choose to measure it. The dual nature of matter is a product of our interactions with matter, rather than some intrinsic property of a “reality” with an objective, independent existence. “Virtual states are part of the realm of potentiality in physical
reality because they contain the future empirical possibilities of the universe” [3]. This is eerily reminiscent of ethe way invisible software contains the potential for the future “empirical” (quantifiable) audio-visual outputs it displays in response to human interaction.

Complementarity is the conceptual tool we use to simultaneously hold both descriptions of matter, particle and wave, as equally “real”, but mutually exclusive because of the independence of their contexts. From the sub-plank length quantum perspective, subatomic particles and the observer –along with their experimental apparatus — must be considered a new system rather than separate “individuals”. It is the context of the observer that determines what description to use. A model of discrete parts makes sense when describing the mechanics of the heart, but it tells us nothing about the mystery of “life” itself. Life, like intelligence or the color red, is an emergent effect that cannot be reduced to their constituent components: cells or photons. But quantum mechanics reveals something much more fundamentally odd about the character of “reality”: the observer cannot look at a quantum particle without affecting it.

The process of measurement translates the virtual to the physical. When the ensemble of quantum mechanical possibilities (the wave function ) breaks down, one of the various possible outcomes becomes reality. When detection happens, new information is put into the world. This is not an epistemological issue, but rather ontological. There is a virtual invisible dimension to reality that directly affects the material “visible” dimension in a way that is impossible to completely quantify.

La duplice natura dell’arte digitale

“Software is an abstraction that is experienced through its instantiation during runtime” [5]. Conceptual dualism and holism are paradigms that appear again and again in works of digital theory, which must balance the discrete states of bits…

“”By its very nature, digital representation requires the breaking apart of phenomena and their representation by symbolic bits. …with the dynamic processes of systems.“In that a discrete data object (datum) can be considered a (unity), it is a unity having parts (or the potential for parts) and yet is simultaneously a part. The datum is a prehension of its antecedents and concomitants and, by degrees, acts to prehend a larger system which prehends itself”.

Scott Snibe’s “Fuel” is downloaded to the user’s desktop where it turns the IP nodes of your network into a field of glowing stars that react in real time to your on-line activity. The immaterial information provided by the separate and discrete nodes of your network are recontexualized and processed into a single visual display. Geographically distinct components are linked into a single viewing space through the interaction of human input with Snibe’s software. On one level, there is the ontological dualism of material data vs. material visualization, but there is also the ontological dualism of part versus whole, object versus system.

The project “A-Volve” by Christa Sommerer & Laurent Mignonneau, translates the physical input of visitors interacting with a giant touch-screen into a digital ecosystems of strange luminous creatures fighting for survival. With multiple visitors drawing on the same giant tabletop screen, we have the input of many human components with the artists’ designed algorithms that lurk invisibly behind the scenes. These algorithms function as the ʻlaws of natureʼ and hence have both an ephemeral existence as concepts and an empirical existence through their affects on the behavior of “things” in the world.

There is a peculiar relationship between the mostly hidden backend of code which constitute a convergence of language and mathematics- and the multi-sensory “display” it can produce: an identity in the sense of a
sameness in different instances (code/results), each of which takes a very different form yet, on one level, is one and the same. (Christiane Paul)

The manipulation of invisible data into a visible display is at the heart of the web based work of Robert Hodgin. His web site, “Flight 404” , explores the dynamic variability and liquidity of form of digital physics.

Some digital artists exploit the medium’s dual ontology by deploying multiple levels of interactivity in a single project. The result is a blurring of boundaries between the virtual world of the Internet and the physical world of our bodies. The same blurring of boundaries– the same ontological dualism—appears in quantum mechanics, which describes a photon as both quantum wave and sub-atomic particle.

“one trees” by Natalie Jerimenko consists of hundreds of trees planted around the San Francisco Bay area linked together through the internet to virtual trees, creating a “networked instrument” that monitors the health of the environment. As “one trees” is not simply an object we can locate in any one place, though it has object like
components, but also needs to be understood as the sum of the interactions of these components: the biological trees planted in different locations in physical space, along with their digital tree counterparts in cyberspace, and the human social network that is created by the project’s human participants. “one trees” reveals another conceptual dualism: “art can be propositional and computational as much as visual or metaphoric”.

Reynald Drouhin “des frags” asks the visitor to upload an image from their computerʼs library. After the visitor selects amongst several options, “des frags” executes its program. “des frags” criss-crosses the globe in a mere instant, tearing through ““web windows” – a continuous breakage whose splinters, far-away and indeterminate, are recomposed….”(Drouhin). A few minutes later an original work of art is sent to the visitor by e-mail. The result is an abstract mosaic suitable for printing on a single sheet of paper- or, as Drouhin calls it, a “Defragmentation of the Internet by Images”.

Because the visitor’s collaboration with ”des frags” produces a physical object, the work offers the experience of crossing the boundary between the virtual world (a world of possibilities) and the physical world. This is not unlike our interactions with a quantum system in that the collapse of the quantum wave function- a virtual entity- produces a “observable outcome” – a physical entity.

Quantum tunneling is the idea that all objects also have a wave like character that is spread out in time and space. Throw a tennis ball at a wall until the end of time and eventually it will pass through the other side, as if violating the laws of physics. Yet there is no violation, only a statistical rarity. What some might call a miracle is perfectly plausible within the bounds of quantum physics. Victoria Vesna’s “quantum tunneling” plays on the idea that “objects” – including the visitors to her installationalso have a dual wave-like nature that goes urecognized except at the quantum level.

A “tunnel” connects two identical spaces in which images of the audience are projected and distorted. The visitor swipes a finger over a specified surface, leaving a genetic trace. While doing so, the visitor’s image is captured and presented in conglomeration with the face of another visitor. The recognizable faces are juxtaposed and become distorted. When another visitor passes through the tunnel, the facial images are again disturbed and altered, fractured into particles and waves.

Conclusions

What good is analytic reduction when entanglement –a form of strong coupling- lends more reality to a composite system that to its parts.” But what is really meant by this notion of “more reality”? In quantum terms, “reality” simply means a quantum state according to our definition”.

But perhaps it is more useful to say that “holism” constitutes another “order of reality”. The composite or higher (hierarchical nesting) “order of reality” of holism that we find in works of interactive media art and entangled
quantum particles, is a challenge to the reductive “either/or” logic of classical physical dualism. Holism is an ontological property that emerges from conceptual dualism. There are material “things” we can clearly measure and is also the relationship between these “things” as a non-material condition that is equally “real”, but much more difficult and at times impossible to fully quantify. Both aspects of reality are equally valid depending upon our perspective and our context. In order to grasp the immaterial materiality of digital media we need the “both/and” logic of conceptual dualism of complementarity.

A work of interactive media — like a quantum system– is both material and immaterial, static (the code) and the dynamic interpretation that code (the running program), just as a photon is both a measurable object (a particle) and a swarm of virtual particles (the probabilistic wave function). Roy Ascott proposes “art has shifted its concern from the behavior of forms to forms of behavior”. Clearly art has not forsaken its interest in form, but it is equally true that new kinds of art, such as interactive digital media, require a new set of criteria.

This does not invalidate formalism, nor does quantum mechanics invalidate Newtonian mechanics. It all depends on the context of the observer. Different criteria apply in different contexts. The emergence of complex phenomena, such as cognitive thinking, exists at the level of the system, rather than the level of the object. We require conceptual bifocals. Complementarity is a model for understanding the conceptual dualism of both the physical and the virtual.
