Abstract

Interview with Hiranya Peiris, Professor of Astrophysics at University College London and Director of the Oscar Klein Centre and Professor of Cosmo-Particle Physics at Stockholm University. Peiris describes her dual affiliation, she discusses diversity in STEM over the past year, and she surveys the current interplay between theory and observation in her field. She recounts her childhood and family heritage in Sri Lanka and the circumstances that led her family to relocate to the United Kingdom. Peiris describes her interests in math and science the opportunities that led to her enrollment at Cambridge as an undergraduate and a formative experience at JPL in California. She explains her decision to pursue a PhD at Princeton, where she worked with David Spergel on WMAP. Peiris discusses her postdoctoral appointment as a Hubble fellow at the University of Chicago to continue to work on WMAP, and her subsequent work as a Halliday fellow at Cambridge. Peiris discusses her work on the Lyman-alpha forest and her faculty appointment at UCL where cosmology was just coming into maturity. She conveys the excitement as WMAP results were becoming available and her contributions to the search for dark matter. Peiris explains why the LSST project is so significant, what it was like to win the Breakthrough Prize, and the gratitude she feels by having eminent physicists as mentors. At the end of the interview, Peiris emphasizes the importance of following inquiry into the most fundamental questions surrounding gravity and space time, and why Stephen Hawking remains an intellectual inspiration to her.

Abstract

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.

Abstract

Extensive interview covering early life and family in New York and Maine; schooling and early interests in astronomy in New York City; observing Halley's comet in 1910; World War I and college years at Harvard University majoring in chemistry; medical degree from Cornell University; contacts with Henry Norris Russell and Harlow Shapley, and decision to move into astronomy; graduate work at Princeton; postdoctoral work and staff position at Mt. Wilson in the 1930s; interests in instrumentation and planetary atmospheres; the role of the Schmidt Camera in spectroscopy; planetary spectroscopy and the nature of the interstellar medium; founding of the FAR (Fund for Astronomical Research); World war II and work in optics for the National Defense Research Committee (NDRC) of the Office of Scientific Research and Development (OSRD); travels to Britian during the war; decision to leave astronomy after the war; move to Rochester for biophysical research; return to astronomy in 1952. The second interview concentrates on his contacts with Henry Norris Russell and activities during World War II.
