Gabriela Barreto Lemos – Quantum Photography – Brazil

Quantum photography technique that allows you to record images without light passing through the object.

Typically, a beam of light interacts with an object; In this same beam, the image of that object is formed, which is recorded on a camera, on paper or directly into the eye. This research used two quantumly entangled photon beams. An infrared photon was directed at a silicon wafer engraved with the image of a cat. The other photon, red, was sent on a different trajectory, did not pass through the silicon plate and was detected by an EMCCD (electron-multiplying charge-coupled device – a photographic camera with sensitivity to very low intensity light). The image of the cat engraving was recorded by the camera, which only detected the red light, which did not touch the engraving. It is the first time that an image has been captured in a beam of light that has not interacted with the object that produced the image.

The experiment, led by researcher Gabriela Barreto Lemos, was carried out at the Institut für Quantenoptik und Quanteninformation in Vienna, 2014.

The technique has potential for applications in indirect image capture, from medicine to quantum computing.

Skin-awareness
The immersive space morphs and alters with light and becomes solid, its pressure composing and decomposing the self-awareness of skin. The dancer’s body is extended and manipulated as a conscious entity, exceeding the physiological object. The constant feedback between the body’s trajectory and interaction with the environment changes the nature of the object itself.

Pyroclastic Trails
The work shows volcanic rocks rising from the ground that create trails of pixels. The layering of tezontle is generated by a software by modifying the size, speed, trajectory and selection of rocks from a database of photogrammetric 3D scans. Made in November 2019 in collaboration with UNAM’s Instituto de Geografía during a residency for Connecting the Dots, the work is related to research on the impact of mining activities in extinct volcanoes of Sierra de Santa Catarina located south of Mexico City. The video also shows Orbiting Bauxite and 3542 of the Meteors body of works.

Supraspectives
In the process of creating Supraspectives, the artist duo Quadrature has gathered the data of 590 (recent & former) spy satellites, whose trajectory the installation follows. A third of them can be considered space trash, as they are obsolete or damaged, but still, they continue overflying us. The installation calculates the paths of all those satellites in real time and speculatively reconstructs the view they are capturing, offering artistically intervened images of what the satellites could be observing. Mainly satellites passing near the exhibition venue are selected, combined with other specially interesting or suggestive satellite images. Additionally, a specifically built motorized antenna on the roof connects live with the satellites overflying Tabakalera, transforming their real radio signals into sound. Everytime the installation connects with a satellite, the screen shows the data relative to it, such as country of origin or year of launch.

Convergenze parallele

Convergenze parallele is an audiovisual installation in which airborne dust particles passing through a beam of light are tracked, visualized, and sonified in realtime by a custom software system. The installation reacts to air movements in the exhibition space, allowing the viewer to see and hear the amplified movement of dust particles. “Convergenze parallele” explores the poetic potential of revealing and transforming the imperceptible. The custom software uses a video camera to capture the activity of dust articles passing through the beam of light. It then analyzes the video signal to track the location of individual dust particles, and reveals each particle’s trajectory in the image-processed projection. The physical particles draw traces of their otherwise invisible motion on the digital screen. At random intervals, the software artificially saturates the system by briefly activating the fan-a cloud of dust fills the beam of light and creates dense and stunning patterns of particle trajectories and sound.

the Indistinct Notion of an Object Trajectory

Ryota Matsumoto’s drawings develop and demonstrate the hybrid/multi-layered process where varying scale, juxtaposition of different forms, intertwined textures/tones are applied to reinvent and question the spatial conditions of architectural drawings. His work explore a hybrid drawing technique combining both traditional media (ink, acrylic, and graphite) and digital media (algorithmic processing, scripting and image compositing with custom software ) .

Re-projection: Hoosac

Influenced by the utopian projects — and notable failures — of innovative artists and designers such as Buckminster Fuller, Frederick Kiesler, and Charles Eames, Tobias Putrih likens his works to experiments, or design prototypes. His use of cheap materials, including egg crates, cardboard, and plywood signify both a sense of potential and impending collapse. Many of the artist’s works reference the architecture and spectacle of the cinema: a space suspended between fantasy and reality, image and environment. With Re-projection: Hoosac Putrih distills the cinema to its most basic element: fishing line stretched across the gallery mimics the conical trajectory of a beam of light. A spotlight hits the strands of monofilament which in turn become a screen, reflecting an image in illuminated dots. Inspired by the Hoosac Tunnel just east of North Adams — a storied, engineering marvel that draws ghost-hunters to the area — Putrih’s tunnel is, likewise, both real and a representation, an optical trick that invites both wonder and investigation.

Shooting Thoughts
Филип Вилас-Боас
filipe vilas-boas has created an interactive projection called ‘shooting thought’ which enables people to generate star constellations by sending thoughts through their mobile device. these ideas connect to lasers and become shooting stars that follow any possible path that paris’ saint-eustache church’s architecture allows. the project was co-commissioned by art, culture et foi and nuit blanche paris.The pillars are the launch-pads that send the stars past arches and vaults to their destinations on the ceilings. each one reaches its on place, at its own speed and with an individual trajectory. ‘shooting thoughts’ means each person who engages with the lasers, can send their own star and be part of the display.

Impermanence Trajectory: the limbic nest.

Earlier AUJIK referred to this in terms of natural and unrefined computation but after German AI scientist Jurgen Schmidhuber introduced the more comprehensive view of Panacomputationalism it’s been adapted.In this manifestation called ‘Impermanence Trajectory: the limbic nest’, this idea is explained through a sacred rock located at an ancient Yamabushi(4) area called Ishiyama.A rock consist of approximately ten trillion trillion atoms in a kilogram of matter, electrons scattering and bouncing back and forth making it a very vivid space with a vast computational potential.
