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.

Subject(s): physics, astronomy Astrophysicist Paul Coleman and expert ocean navigator Kalepa Baybayan visited the Exploratorium as advisors to our Polynesian Navigation project—a large-scale Web resource (launching April 2010) that will feature the astounding navigation practices of the Pacific Islanders, who were expertly navigating the Pacific thousands of years before the arrival of Europeans.
Paul Coleman works at the University of Hawaii Institute for Astronomy, where he concentrates on the large-scale structure of the universe. Kalepa Baybayan is an expert navigator who mentors Hawaiian youth in native navigation practices. Both men are native Hawaiians. We spoke with them about traditional navigation practices, the balance between science and spirituality from a native perspective, and the benefits of being grounded in one’s culture.
