Astronomical photometry

Interview with John Thorstensen, Professor of Physics and Astronomy at Dartmouth and President of MDM Observatory. Thorstensen narrates the story of George Wallerstein bugging his thesis committee at Caltech and he discusses his current work on cataclysmic binary stars. He surveys all of the exciting developments in the world of observational astronomy and he explains some of the administrative considerations in the way Astronomy and Physics is divided at Dartmouth. Thorstensen describes his undergraduate education at Haverford, where he pursued his interests in astronomy, and he explains his reasons for attending Berkeley for graduate school to work with Stu Bowyer on X-ray sources. He discusses the opportunities that led to his faculty appointment at Dartmouth and he explains his increasing involvement with the MDM collaboration. Thorstensen describes his formative collaboration with Joe Patterson and the evolution of Astronomy developing into its own discrete program at Dartmouth. He explains the value of both photometric and spectroscopic applications and the value in using digital detectors. At the end of the interview, Thorstensen discusses his recent interests in white dwarf binaries, the contributions of amateur astronomers in making significant discoveries, and some of the surprises he has experienced during his career studying cataclysmic binaries. 

Interview covers Sandra Faber's childhood experiences; parental background; early reading; early preference for steady state model; relationship between questions and answers in science; confusion over being a woman and being a scientist; lack of female role models in science; education at Swarthmore and the influence of Sarah Lee Lippincott there; graduate work at Harvard; husband's job; graduate work at the Department of Terrestrial Magnetism; influence of Vera Rubin; early results of dark matter by Morton Roberts in the late 1960s; thesis work on photometric studies of elliptical galaxies; community's attitude toward excess mass in rotation curves in the late 1960s; motivation for work on the Faber-Jackson relationship between luminosity and velocity dispersion; motivation for work with the Seven Samurai (Burstein, Davies, Dressler, Faber, Lynden-Bell, Terlevich, and Wegner) on peculiar velocities; attitude of the community toward the Seven Samurai work on peculiar velocities; attitude toward the big bang assumption of homogeneity; attitudes toward the horizon problem, the inflationary universe model, missing matter, the flatness problem; discussion of what types of problems can be addressed in cosmology; attitude toward Center for Astrophysics (CfA) red shift surveys by de Lapparent, Margaret Geller, and John Huchra; importance of understanding how large-scale structure is formed; issues of gender in science and the experience of being a woman in science; the ideal design of the universe; the question of whether the universe has a point.
