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.**We are on a winter hiatus, come back for more new episodes in February, 2014!

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.

Science in the City:  Inner Voice (Clip)
Running Time:
00:03:33
We all have an inner voice that pipes up now and then: "Don't eat that cake," it says, or "Where are my keys?" Does this type of self-talk serve any purpose? Recent research suggests that it does, helping us to build motivation and control impulses. Here, one man confronts the power—and the limitations—of his inner voice.

Science in the City:  Synesthesia: The Smell of a Sound, The Taste of a Color (Clip)
Running Time:
00:05:30
Monday is spiky. The number nine is orange. The letter F smells like smoke. Roughly one percent of people experience such blending of the senses, known as synesthesia. In this episode we meet Bryan Alvarez, a doctoral candidate at the University of California at Berkeley, who is researching the neural mechanisms of synesthesia in an effort to explain why only some of us experience this cognitive crosstalk.
