How can a wind-powered sailboat move faster than the wind? Why do the America's Cup sails look like airplane wings? With the beginner in mind, Exploratorium senior scientist Paul Doherty introduces the basic physics of sailing and sail design. See the subtle, mesmeric effects revealed by slow-motion observation of three iconic exhibits: Circling Wave Umbrella, in which spinning fabric forms pockets of swirling air; Rift Zone, a miniature geothermal landscape created by air bubbling through fine sand; and Vortex, a swirling vortex of water in a hydrodynamic dance with gravity. NPR, or Neighborhood Public Radio is an artists collective and community radio project founded in 2004 by multimedia artists and educators Lee Montgomery, Jon Brumit and Michael Trigilio.
Acting as a traveling band of guerilla broadcasters, NPR personnel have hosted thematic broadcasts from San Francisco to Serbia, including a stint at the 2008 Whitney Biennial. What is Neighborhood Public Radio? Imagine a storefront community radio station open to you. You get access to the airwaves regardless of your qualifications or message.
We caught up with the founders of the now-decentralized NPR team, in Oakland, Chicago and San Diego to talk about the technical, social and political aspects of broadcasting, and about their tattoos.
As a special treat for our listeners we thought it would be fun to ask Lee, Jon and Michael to create a new Audio-Art piece for our Podcast series. The idea was simple. They would each create a composition that was no more than 5 minutes long, and we would layer all three parts together to create a single new work. Visit the link at the bottom to hear the results.
View a selection of video clips from three exhibits that are part of the new Outdoor Exploratorium collection at Fort Mason. SETI is a scientific effort seeking to determine if there is intelligent life outside Earth. We were at Aricebo Radio Observatory in March 2003 when scientists listened to the most promising transmissions from UC Berkeley’s SETI@home search. Join the Exploratorium’s Ron Hipschman and special guest Dan Werthimer, chief scientist and principal investigator for the SETI Institute’s efforts, including Arecibo Observatory’s search of artificial radio signals coming from other stars. How can a mathematical equation frame the question of life in the universe? We’ll talk with Frank Drake, one of the founders of the SETI Institute, about his famous equation and how it frames the search for signs of intelligent life in the universe. Watch as Exploratorium staff and local teachers compete for the title of Iron Science Teacher. Each contestant has 10 minutes to make a science lesson out of a secret ingredient. In this special Halloween edition, today's secret ingredient is: Plastic Bags! Our team of middle school students from the Aim High program investigates new technologies that use our unique physical traits as tools for identification. Vox Unlocks tunes into voice recognition Why do many things sound different underwater? How are echoes made? Can you feel or see sound? Join us as we delve into the mysteries of sound. This webcast will feature an Aim High student demonstrating how to make a membranophone; Exploratorium physicist Dr. Paul Doherty modeling sound with ringing aluminum rods, corrugated plastic whirlies, and a slinky; and Marco Jordan, lead educator in the Exploratorium's Outreach program, demonstrating sound science with a "whine" glass and a singing bowl. Our annual tradition of robot races and wrestling with a high tech twist, the Robot Races are produced in conjunction with the San Francisco Robotics Society. Watch the 'bots battle it out with hosts Leo Laporte and SFRSA President David Calkins.
