Friday was Arts et Metiers museum day. It houses many old scientific instruments and artifacts. A replica of Lavoisier's lab, many old meter bars, examples of how domes were erected, a scale model of the enlargement of the head of the Statue of Liberty, and lots more interesting items of scientific interest. They even have the pre-beta model of the ipod, the Sony walkman! Pictures are at random of various items in the museum. There is also a working Foucault pendulum. How did they figure out that the earth rotates just from a pendulum? Beyond my brain. It was a very interesting place to visit. They also had a fullsize model of the plane Louis Bleriot flew across the English Channel in 1909. Imagine, 6 years from the first flight, Bleriot flys across the Channel, approximately 22 miles.
