Physicist JAMES TREFIL (pronounced "TRUFF-el"). His new book, "A Scientist in the City," (Doubleday) is a exploration of how the laws of nature and technology came together to make our cities. TREFIL starts by looking at cities as natural ecosystems, and then looks at the key scientific discoveries that made cities possible. TREFIL has written more than ten books on science, including, "1001 Things Everyone Should Know About Science." TREFIL is also a regular commentator for NPR, and he teaches at George Mason University.
