Looming over San Francisco since 1973, Sutro Tower's antennae transmit and receive radio and television signals to the nine-county SF Bay Area. Perched above Twin Peaks, the tower has become a local icon, now revered as much as it was abhorred when first built. Visit the tower with us to find out what’s on it, what’s underneath it, and its history, including its transformation from eyesore to icon. What is Community Radio? The DJs and station managers at KPOO, KUSF in Exile, Mutiny Radio and Radio Valencia give us some insight into community radio in the Bay Area, how it works and the challenges they face.
http://radiovalencia.fm/ Join Exploratorium staff scientist Ron Hipschman as we visit Dan Werthimer, Director of the SETI Research Center at UC Berkeley. SETI conducts experiments searching for electromagnetic signatures of intelligent extraterrestrial civilizations, spanning wavelengths from radio to visible light, over ten orders of magnitude in characteristic time scale. How can a bugle make so many notes even though it has no valves? We’ll find out about how waves can fit into pipes, strings and rods in this webcast.
Join Ron Hipschman at a live webcast where he’ll investigate sound waves, interference, beats, and harmonics. What is sound? How high a pitch can you hear? Can two sounds add up to no sound? Explore these questions and more in this resonant presentation. Watch the Exploratorium's construction process from December 2010 to November 2012 in under two minutes. Come see for yourself—doors open at Pier 15 on April 17, 2013.

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.
