Reflections:  Testing the Giant Mirror's Sphericity (Clip)
Running Time:
00:04:49
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.
