At the Giant Mirror, Senior Staff Scientist Paul Doherty demonstrates a simple way of locating a real image—an image that floats in space in front of the mirror. Senior Staff Scientist Thomas Humphrey invents a simple experiment to see if the Giant Mirror is spherical or parabolic, and then to see if it's perfectly spherical. By placing a Styrofoam ball at the center of curvature, he's able to prove that the mirror is out of pure sphericity by about one-quarter of one degree. Staff Neuroscientist Richard Brown demonstrates that the Giant Mirror reflects infrared radiation as well as visible light.
