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.
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.
