Exhibit developer Erik Thogersen backs away from the Giant Mirror. Watch his image change as he passes through the focal point, then continues on past the center of curvature. 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. Our host, Stephanie Chasteen, shares some fun facts and activities having to do with the science of sound.
Learn how to build a version of a Brazilian instrument called the cuica, which demonstrates principles of sound. This podcast was created collaboratively in a teacher workshop at the Exploratorium.
Terje Isungset is one of Europe's most accomplished and innovative percussionists. With over two decades experience in jazz and Scandinavian music his work travels far beyond traditional boundaries. He's become more like a cross between a sound artist and a shaman. Isungset crafts his own instruments from natural elements found in Norway such as arctic birch, granite, slate, and even ice. View a selection of video clips from three exhibits that are part of the new Outdoor Exploratorium collection at Fort Mason. This video captures the energy and excitement of traversing across the sea ice to the Offshore New Harbor Field Camp. In this video, ride in a special Mattracks truck across the ice sheet with geologist Christina Riesselman as she travels with ANDRILL Staff Scientist Richard Levy from McMurdo Station to the ANDRILL drill site. They investigate the truck’s special wheels, observe beautiful panoramas of the Transantarctic Mountains, and hear the drill running at the drill site.
