Segre Gino

Dr. Segre is physics professor at the University of Pennsylvania. His uncle, Emilio Segre, was a winner of the 1959 Nobel Prize for the discovery of the antiproton. An older brother is a physicist, and an additional “six or seven” cousins do physics, too. But Dr. Segre, 68, has a second profession: he writes popular books about the history of science. His most recent book, “Faust in Copenhagen: A Struggle for the Soul of Physics,” about a 1932 conference at Niels Bohr’s Institute for Theoretical Physics, has just been published, drawing praise from reviewers.
