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.
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.
