Arts/Sciences#11: Evelina Domnitch & Dmitry Gelfand
Lecture & Sonolevitation performance
Dmitry Gelfand and Evelina Domnitch (Portable Palace) create sensory immersion environments that merge physics, chemistry and computer science with uncanny philosophical practices. During the past decade, they have collaborated with numerous scientific research facilities, including the Drittes Physikalisches Institut (Goettingen University, Germany), the Institute of Advanced Sciences and Technologies (Japan), and the Department of Physics and Astronomy at the Vrije Universiteit (The Netherlands). From 2008 to 2011, the duo was member of the Optofonica Lab for Immersive Art-Science co-founded by TeZ in Amsterdam and is now setting up their own new organisation Synergetica.
After the lecture, Dimitri and Evelina will perform Sonolevitation, an acoustic levitation performance.
A 15 kHz acoustic vibration is vertically reflected at a precise distance from its source, generating a standing wave that levitates leaves of gold. The air between the intonator and the reflector is evenly divided into alternating areas of dynamic acoustic pressure and vacuous anti-nodal pockets. Within these pressureless voids, fluids and solids can be suspended and spun by the surrounding sound fields. An evocation of the weightless, frictionless environment commonly found in outer space is coupled with an extended opto-aural awareness of space-time itself: the floating objects modulate the frequency and amplitude of the standing wave that levitates them, consequently influencing one another’s motion -- each part is an inseparable, co-emergent reflection of the whole.
