What is light? How is it made? In this video, staff physicist Ron Hipschman will talk about and demonstrate light, it's features and various ways it can be made as well as how colors mix. Exploratorium neuroscientist Richard Brown discusses how we see color, how color vision evolved, why color vision varies from person to person, and how the scientific understanding of color vision has led to technologies such as color photography An inspiring conversation with Annea Lockwood, New Zealand-born experimental sound artist and musician known for her boundary-burning explorations of the world of natural acoustic sounds and environments.

Composer and performer Pauline Oliveros has been a pioneering figure in American music for over four decades. In this intimate talk recorded at the Exploratorium on February 21, 1985, Oliveros discusses her decision to quit teaching and flee to Italy with her accordion, her appreciation of the Grateful Dead's concert sound system, and the perils of the squeezebox. She also takes audience questions and performs "Rattlesnake Mountain" live. In this extensive talk from 1985, prolific American composer, musician, and self-proclaimed 'student' Anthony Braxton discusses many elements of his musical work. Because Braxton sees his musical output as part of larger constellations of culture, politics, and spirituality, his talk is huge in scope, and his language sometimes dizzies while it dazzles. He discusses his personal rejection of music for entertainment, and considers instead what music might do to further universal values. He also takes audience questions and plays excerpts of some of his recordings. This talk will amuse, awe, challenge, and inspire interested parties old and new. Join A, K. C. Cole, author of Something Incredibly Wonderful Happens: Frank Oppenheimer and the World He Made Up, in conversation with Exploratorium Director Dr. Dennis Bartels, eminent San Francisco Chronicle science writer David Perlman, Cinema Arts Director Liz Keim, and Exploratorium physicist Thomas Humphrey. A question-and-answer session followed the panel discussion.
Is water ice present or absent in a crater near the moon's south pole? NASA’s Lunar CRater Observing and Sensing Satellite (LCROSS) mission is seeking a definitive answer. Join Exploratorium staff for a special Webcast featuring live coverage of LCROSS crashing into the moon! Our team will be broadcasting live from the 36" Refractor Telescope at Lick Observatory on Mt. Hamilton, where we’ll watch the impact and investigate how this intentional crash could reveal the existence of water ice. In this panel discussion, the panelists will examine the impacts of climate change on Hawaiian ecosystems and populations. The panelists will include:
Phil McGillivary, Leon Geschwind, Amber Inwood, and Ku’ulei Rogers. As part of the ECHO Climate Change Symposium, join artist Xavier Cortada as he discusses some ways that the world is participating in actions around climate change.
