Cities are known to produce a lot of light pollution, making it a challenge for astronomy enthusiasts to view the heavens within city limits. For us in the SF Bay Area, these issues apply, however, exciting results can still be attained between sky gazing and learning about how we all fit into this big thing we call "space". Urban Astronomer Paul Salazar, The Exploratorium's very own Adam Esposito and more demonstrate how to deal with the parameters and the unforgettable experiences that await with simple to no equipment, the right conditions, and some decent timing.

At the southern end of the Golden Gate Bridge, a construction project to rebuild the elevated freeway ramp formerly known as Doyle Drive is underway. Senior bridge engineer John Walters tours us through some of the new seismic technologies being installed, including a seismic joint designed to handle several feet of longitudinal movement and a spherical bearing that allows for three-dimensional movement. Walters also points out a temporary structure built over the historic Presidio Pet Cemetery to protect the grave sites while providing a platform for the construction overhead.

John Cage was one of the most influential composers in modern American music. He raised fundamental questions about the nature of music, and invigorated, provoked, and perplexed audiences throughout his long career. In this lecture from 1987, excerpts of his work are played and discussed. Afterwards, Cage takes questions and shares his thoughts on subjects ranging from the origins of his impulse to make music-"Many composers hear music before they write it, but I write music in order to hear it"-to using chance to create without ego or intention. He asks why we should listen to music instead of just listening to the sounds around us, and answers: "There's no reason."
