We’ve long marveled at artist John Edmark's (previously) kinetic objects that function as a medium to express a variety of mathematical formulas and concepts. The spiral-like sculptures often defy description and even when looking at them it’s hard to understand how they work, something he refers to as “instruments that amplify our awareness of the sometimes tenuous relationship between facts and perception.” The folks at SciFri recently visited with Edmark in his studio to learn more about how he works and to catch a glimpse of some rather unusual sculptures he’s created over the last few years.
