Rockefeller University

In this interview, Oscar Wallace (Wally) Greenberg recalls his experiences growing up in New Jersey as the child of Jewish immigrants from Eastern Europe and his accelerated education at Rutgers University and Princeton University, where his advisor was Arthur Wightman. He discusses his dissertation called “The Asymptotic Condition in Quantum Field Theory,” postdocs at Brandeis with S. S. Schweber and at MIT with Francis Low, and early work on high-energy limits and the general structure of quantum field theory. He reflects on his landmark proposal that quarks have a three-valued charge, later called color, as well as the delayed acceptance of the idea, his prediction of later measurements of the excited states of baryons, and his propensity not to promote his contributions. Greenberg also discusses his acceptance of a position at the University of Maryland, where he would spend most of his career, as well as visiting appointments elsewhere, and he offers anecdotes about his interactions with J. Robert Oppenheimer and Albert Einstein at the Institute for Advanced Study. The interview concludes with discussions of what remains unknown in particle physics and of cosmology as a “laboratory” with particle energies not available on Earth. A technical addendum to the interview lists 24 of Greenberg’s key contributions to physics.

Interview with William Marciano, Senior Physicist at Brookhaven National Laboratory. Marciano recounts his upbringing in Brooklyn and his early interests in science, and he describes his undergraduate work at RPI and then NYU. He explains his decision to remain at NYU for his graduate research to study under the direction of Alberto Sirlin, and his thesis research on dimensional regularization. Marciano discusses his postdoctoral appointment at Rockefeller University where he worked on the SU(5) model of Grand Unification, and the opportunities that led to his promotion there to a faculty position. He explains his short tenure at Northwestern before joining Brookhaven, where kaon physics was taking center stage, and where ISABELLE was being built. Marciano discusses the origins of the Lab's g-2 experiment, and he compares the demise of ISABELLE to that of the SSC, for which he served on the program advisory committee. He describes the success of RHIC, and he discusses his research focus on muon and neutrino physics for the Lab's AGS program. Marciano explains his proposal that led to DUNE at Fermilab and he surveys his long record of advisory work for the HEPAP community and how the United States has contributed to the LHC. He reflects on winning the Sakurai prize and his contributions in establishing the validity of the Standard Model at the level of its quantum corrections. Marciano describes his recent work in dark physics, and he surveys the current state of play in muon physics and the Intensity Frontier. At the end of the interview, Marciano compares the diffuse network of the U.S. National Lab system to the centrality of CERN in Europe, and he explains why his work on DUNE and CP violation has been so personally meaningful.

Interview with John K. Delaney, Senior Imaging Scientist at the National Gallery of Art. He discusses the datasets he has been analyzing during the pandemic, and he recounts his childhood in Boston. Delaney describes his experience at Rockefeller University and his interest in phototherapies and measuring porphyrins under the direction of Dave Mauzerall. He discusses his postdoctoral research at the University of Arizona to study rhodopsin molecules and following the changes in protein structure after excitation by light. Delaney describes his interests in biophysics and his subsequent postdoctoral position at Johns Hopkins as an NIH fellow working in the lab of Sriram Subramaniam, before taking a job in industry as an optical engineer. He explains the circumstances of his initial involvement at the National Gallery of Art and the Gallery’s realization of the value of spectroscopy for analysis and preservation of paintings. Delaney describes how he built an expertise on hyperspectral imaging. He explains why the Gallery supported this work and how a global community developed for this field. He explains the value of his work for art authentication and the opportunities he has pursued in public outreach. At the end of the interview, Delaney explains some of the key physics concepts that inform his work, and he describes his ambition to write a book on reflectance imaging spectroscopy of paintings.

In this interview, David Zierler, Oral Historian for AIP, interviews Anthony (Tony) Zee, professor of physics and a member of the Kavli Institute for Theoretical Physics at UC Santa Barbara. He recounts his family’s escape from revolutionary mainland China to Hong Kong, and then to Brazil where his father pursued economic opportunity in Sao Paulo. Zee explains the opportunities leading to his undergraduate study at Princeton, where John Wheeler was a formative influence, and he describes the connection from Wheeler to Steve Weinberg that allowed him to pursue his graduate studies at Harvard where ultimately he studied under Sidney Coleman. He discusses his postgraduate work at the Institute for Advanced Study where he worked with Michael Green and Bob Carlitz on hadron-hadron scattering. Zee explains his reasons for accepting his first faculty appointment at Rockefeller University and all of the contemporary excitement surrounding asymptotic freedom and renormalization. He describes his return to Princeton, where he stayed until he was denied tenure and he moved to Penn. Zee explains the origins of the ITP (before Kavli’s endowment made it the KITP) and his interest in coming to Santa Barbara after a brief appointment at the University of Washington. At the end of the interview, Zee describes the pleasures of writing popular physics books, he emphasizes the importance of reinventing oneself within and beyond the broad world of physics, and he shares that his big non-scientific ambition is to have a cartoon submission accepted in the New Yorker.
