Interview with Lyman A. Page, Jr., James S. McDonnell Distinguished University Professor of Physics at Princeton. Page recounts his childhood in Palo Alto and then in Maine, and he explains why his experience at Phillips Exeter Academy was too structured for his sensibilities. He describes his undergraduate education at Bowdoin, where he discovered his interest in physics and general relativity in particular. Page discusses his research at the cosmic ray station at the South Pole with Martin Pomerantz to look for neutrons and muons, and he describes his subsequent sailing adventures along the East Coast and to Jamaica. He describes the circumstances leading to his connection with Rai Weiss and his admission to graduate school at MIT. Page discusses what it was like to work with Weiss just as the LIGO endeavor was beginning, and how this fed into his dissertation research and work on COBE under the direction of Steve Meyer. He explains the circumstances leading to his appointment to the Princeton faculty at the behest of Dave Wilkinson, and he describes his increasing efforts to measure anisotropy and to discover new aspects of the universe. Page describes his collaboration with David Spergel on WMAP, and he discusses his contributions to measuring the Hubble constant and serving as an advisor to LIGO. He explains his love for statistical mechanics and its usefulness for microwave background research, and at the end of the interview, Page discusses his current work searching for B-modes at the Simons Observatory and why the future in fine-scale anisotropy is an exciting path for fundamental discovery.
