Science Friday Video Picks

The weekly public radio program, Science Friday, features a video pick of the week as part of its broadcast. In this example, linked below, "artists Michelle McSwain and Ryan Warnberg (known collectively as MRI) demonstrate how to paint with light. The premise: combine LED lights with long photographic exposures. Vision expert Stephen Macknik, of the Barrow Neurological Institute, explains how our visual system prevents us from seeing the world as light paintings." Other videos document the effects of space travel, beach-ready robots, and many other subjects both ordinary and extraordinary.
