Art and physics collide in this expansive exploration of how knowledge can be translated across disciplinary communities to activate new aesthetic and scientific perspectives.Leaning Out of Windows shares findings from a six-year collaboration by a group of artists and physicists exploring the connections and differences between the language they use, the means by which they develop knowledge, how that knowledge is visualized, and, ultimately, how they seek to understand the universe. Physicists from TRIUMF, Canada's particle physics accelerator, presented key concepts in the physics of Antimatter, Emergence, and Invisible Forces to artists convened by Emily Carr University of Art Design; the participants then generated conversations, process drawings, diagrams, field notes, and works of art. The &34;wondrous back-and-forth&34; of this process allowed both scientists and artists to, as Koenig and Cutler describe, &34;lean out of our respective fields of inquiry and inhabit the infinite spaces of not knowing.&34;From this leaning into uncertainty comes a rich array of work towards furthering the shared project of artists and scientists in shaping cultural understandings of the universe: Otoniya J.
