More about the Exploratorium website: Science in the City
Urban environments like San Francisco are full of mysterious natural and human-made phenomena. Why are there so many one-footed pigeons? Where does the sewage go? Why is our “summer” in May and September? The Exploratorium is “taking it outside" to explore these and other questions in engineering, ecology, optics, waves, geology, architecture, weather, and more. Look for new episodes once a month.

Science in the City:  Golden Gate Bridge Dynamics (Clip)
Running Time:
00:06:27
Admit it: Hasn't the Godzilla inside you always wanted to grab the Golden Gate Bridge and shake it silly? Finally, you can. In honor of the iconic span's 75th birthday, Exploratorium exhibit developer Dave Fleming presents a dynamic model of the Golden Gate Bridge. What happens to the bridge during an earthquake? How about strong winds and heavy traffic? The model dances and wiggles realistically, displaying the same vibrational modes and motions that occur in the actual bridge.

Science in the City:  Owls (Clip)
Running Time:
00:05:00
Take a stroll in Golden Gate Park at dusk and if you’re lucky, you’ll hear a sound perhaps unexpected: the hooting of wild owls. Jessie Bushell of the San Francisco Zoo debunks some common myths about owls while introducing us to several rescued owls currently living at the zoo—from a 3-ounce northern saw-whet owl that was hit by a snowmobile to a 10-pound Eurasian eagle owl confiscated from a smuggler.

The end of an era is near: In movie theaters across the country, film projectors are rapidly being replaced by digital projectors. Paul Clipson, projectionist at the San Francisco Museum of Modern Art, gives us what may be a last-chance look at the tools and techniques—including lightning reflexes—at work in 35 mm film projection.

Science in the City:  A Record of the Moment (Clip)
Running Time:
00:05:09
In this age of iPods and MP3s, the vinyl record (still) stands as an object of curiosity and ongoing admiration. What’s the real difference between a 78 and a 45? Why do they call it “cutting a record” when an album is recorded? Music enthusiast Wade Wright of San Francisco takes us back in time to explain the history and technology of vinyl records.

Science in the City:  Homemade Fog with Liquid Nitrogen (Webcast)
Running Time:
00:11:47
Well, we tried our live webcast experiment and had some technical difficulties-there are always potential hazards when you make live programs. Nevertheless, here is the show, and we hope you enjoy it! Since there is rarely fog in the winter in San Francisco, Exploratorium Senior Science Educator, Scientist Eric Muller will create fog using Liquid Nitrogen just outside the Museum.

Science in the City:  Rebuilding Doyle Drive (Clip)
Running Time:
00:03:50
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.
