Since 2002, Segrè has published four books on the history of science. Written together with Bettina Hoerlin, Segrè's "Pope of Physics: Enrico Fermi and the Birth of the Atomic Age" is a biography of the famous Italian physicist Enrico Fermi, whose colleagues referred to him as the Pope due to his infallibility. Fermi has a rich legacy of scientific advances, and is best known for his leadership in building the atomic bomb. "Pope of Physics" was reviewed by The Wall Street Journal and Nature. Segrè's Ordinary Geniuses is a dual biography of Max Delbruck and George Gamow, two physicists who made major contributions to the field of biology with their 'pioneering' spirits and practical jokes. Ordinary Geniuses was reviewed by Jeremy Bernstein in The Wall Street Journal and Jonathon Keats in New Scientist. Segrè's book Faust in Copenhagen recounts how a group of 40 physicists assembled at Niels Bohr's Copenhagen Institute focusing on the discovery of the neutron. On the final night of the meeting, the younger physicists mount a skit that was a parody of Goethe's Faust, adapted to the world of physics. By Segre's description, ‘What the physicists didn’t realize was that within a year, Hitler’s ascent to power would change their world and within a decade their studies of the atomic nucleus would force them to make their own Faustian bargains.’ Faust in Copenhagen was reviewed in the Sunday New York Times book section by George Johnson. Segrè's A Matter of Degrees: What Temperature Reveals about the Past and Future of our Species, Planet and Universe explores temperature’s many mysteries, from the causes of fevers in humans to the origin of the universe. Marcia Bartusiak reviewed Matter of Degrees in The New York Times. The Pope of Physics: Enrico Fermi and the Birth of the Atomic Age will be published on October 18, 2016. Written with Bettina Hoerlin, The Pope of Physics explores the life and career of Enrico Fermi.
Scientific research
Segrè’s research has ranged across several major scientific topics within high-energy theoretical physics, including electroweak interactions to develop better understand of symmetry violations.. Within astrophysics his research contributions have ranged from baryon asymmetry to pulsar kicks. His work includes:Pulsar Velocities and Neutrino Oscillations ; Pulsar Kicks from Neutrino Oscillations ; and Implications of Gauge Unification for the Variation of the Fine Structure Constant.
Personal life
Segrè is married to Bettina Hoerlin, a former Philadelphia Health Commissioner. She is the daughter of Los Alamos physicist Hermann Hoerlin and Kate Tietz Schmid. Hoerlin has chronicled her parents meeting and departure from Nazi Germany in her book ‘Steps of Courage’. Together they have seven children, nine grandchildren and live in Philadelphia.
