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.

Miscellaneous:  Between The Folds Preview (Clip)
Running Time:
00:02:02
The film Between the Folds is a 2009 work by filmmaker Vanessa Gould. Between the Folds chronicles ten artists and scientists who have devoted time to the unlikely medium of modern origami. Vanessa Gould, who has degrees in physics and architecture, explores the expression of mathematics through origami. She became captivated by the art and science of transforming sheets of paper into three-dimensional geometric shapes and exposed a hidden subculture. The film will screen at the Exploratorium on Saturday, October 18th, at 2pm.
