Music is more than meets the ears directly. Just as no sound exists in a vacuum, every space sculpts the sound within it. Like a site-specific equalizer, reflections, absorption, and resonances combine to give each venue a unique acoustic stamp.
A subway tunnel is “live” space, rich with reverberations that trap and reflect sound in a well of hard tile. True to their name, “dead” spaces do nothing: The only sound heard is what travels directly from instrument to ear. An open field is the ultimate dead space.
As you follow this wandering riff, listen to the changes wrought by environment. Distance is also a factor here—the sound you hear is recorded from the camera’s vantage. Which spaces sound live? Which sound dead? Do the acoustic changes affect the feeling of the music?
Saxophonist Michael Pearce plays with the Highwater Blues Band in the San Francisco Bay Area. Watch as the best teachers on the planet battle it out for the title of Iron Science Teacher. In this zany competition teachers will have ten minutes to create a science activity. This week's "secret" ingredient - Valentine gifts! Stepping is rhythmic movement that uses the hands and feet as an instrument. Known best among African American fraternities and sororities, stepping draws on a long African tradition of using the body to make music.
Synchronized movement and chants are coordinated by the leader, or step master. Sometimes improvising, always cultivating their own distinctive moves and rhythms, step teams reflect and reaffirm both the unity and the unique style of their group. NASA's Mars Exploration Rovers, Spirit and Opportunity, have long outlived their life expectancy of three months. Join us as we sum up the rover data and explain how this information changes our view of Mars. After a week of analyzing the data from the Huygens probe, do scientists think of Titan differently? What were the unexpected findings? Which hypotheses were wrong? Which were correct? Join us as we talk to mission scientists at NASA's Jet Propulsion Laboratory and get the latest on this enigmatic moon. After yesterday's historic mission to the surface of Titan, what happens next? What do the new pictures of Saturn's largest moon tell us, and what does it mean for our understanding of earth? After its long journey to Saturn's largest moon, Titan, the Huygens probe is released from the Cassini spacecraft. The Huygens probe completes its descent to Titan, capturing hundreds of images on its way. Join Senior Scientist Paul Doherty as he gives us background on this incredible mission and sets the stage for the first close-up images of this mysterious moon. Join Senior Scientist Paul Doherty as we receive the first images of Titan, Jupiter's largest moon, from the European Space Agency headquarters in Darmstadt, Germany. The Huygens probe, released from the Cassini spacecraft, descended to Titan and captured hundreds of images of this mysterious moon. This short preview clip of the larger B-Roll video has footage of the Exploratorium, inside and out, including scenes of children interacting with museum exhibits. This wobbly luminescent sculpture by Liz Hickok is both art work and a
simulation of how a San Francisco neighborhood might jiggle when the Big One strikes.
