see the video lecture: "Practicing 18th-century Science Today". http://www.ucl.ac.uk/sts/chang/
Hasok Chang is the author of the book _Inventing Temperature_. Educators of science will find his ideas about teaching and communicating science and the notion of "complementary science" interesting and provocative. Lecture includes video from two experimental demonstrations. The first is on the boiling point of water and the second is a basic voltaic cell. He argues that there are important aspects of such familiar phenomena which have never been adequately explained. Harry
