freshphotons: “The camera lucida (light chamber) transforms sound waves directly into light emissions. In a transparent chamber filled with a gas-enriched fluid, several ultrasound transformers produce a constantly changing sonochemical environment. The ultrasound waves’ propagation through the fluid brings about the formation of tiny bubbles whose implosions achieve temperatures that are as hot as the surface of the sun. As a result, sound waves in the form of light are emitted. Evelina Domnitch, Dmitry Gelfand” Aside: I met Dmitry Gelfand at the Perimeter Institute for a workshop yesterday. He should be the Fresh Photons mascot. So amazing.
