Hypernova: 0 I just can’t believe it, But before Reverand Evans sees it, Gotta get this telegram off to the IAU. Supernova, supernova, your models are best it’s plain to see. You’ve got a great big Cray, And it does, what you say, In three dimensions and non-LTE Supernova, supernova, will we ever know you? You live so far away, Beyond the Milky Way, I bet you’ve still got a secret or two. Hi Stan, It’s been awhile. I think the last time we shared together I was still a graduate student and you had either just gone to Santa Cruz or were about to go. Now you are turning 60, and I remember your 30th birthday back at Kellogg. Those were different times: I remember your HP-35 that was stolen. I think it was worth $350. I was still using my trusty slide rule. We all had cardboard boxes full of computer cards and God help us if we dropped one. We used to type them up on the IBM keypunch machines, duplicate them in those big klunky card duplicators (which invariably ate a few), and submit them to the operators for batch jobs on the IBM 360 or run them through the RJET for remote calculations on Berkeley’s CDC 6600. I remember that you and I set up all the statistical model reaction rate calculations that anyone would conceivably (at that time) want from mass 20 on up, and that you took them to Livermore to run. They had LRLTRAN running on CDC 7600s back then, and although most of the results were accessible, some got scrambled up on the tapes and we had to redo them. So much for technology. Kellogg was a great place to work during those years. Pre-Nobel Willy was our leader and BAZ helped with any programming issues. There were technical visits from people like Fred Hoyle, Vickie Weisskopf, Aage Bohr, and other leading scientists. Nucleosynthesis was the business and we all – experimentalists, nuclear modelers, and stellar dynamics folks – worked hard at it. Socially the place had its moments. I remember some good parties and some of our social times at work: lunches at the Greasy, the Athenaeum, or sometimes at the Continental Burger. One time we drank too much beer at the Athenaeum when we went there to watch Billy Jean King beat Bobby Riggs at tennis. But all the time, people were serious about doing the best they could to discover and understand the evolution of the elements. When I first met you, I had just begun my thesis research and was learning about the statistical model of the nucleus, nuclear transitions, nuclear level densities, and thermonuclear reaction rates. You arrived as a postdoc and joined me as a somewhat more experienced mentor and colleague. You were sort of a big brother to me on the reaction rate project. While I was able to teach myself the physics and to evaluate the importance and relevance of alternative models for our work, you had the ability to organize and to get things going. In our work together, this was the most valuable capability I learned from you. I was always OK at solving specific problems, but watching and working with you taught me how to take a big problem, to break it down into bite-size chunks, to analyze the relationships between and importance of the chunks, and to set about their accomplishment. Much thanks. Well, since those days Willy won a Nobel Prize, Supernova 1987 A occurred (and I saw you in the media), and you’ve gone on to a great career in theoretical high energy astrophysics. With the progress of computer technology and power, I’m sure your rotating massive star models are formidable. Congratulations! I left nuclear astrophysics and came to Oak Ridge thinking “Energy is the moral equivalent of war.” I did plasma physics for magnetic fusion for a number of years and, as the fusion program waned, took up charged particle beam dynamics for accelerator physics. It’s challenging and fun work and I am always applying the skills you helped me learn. It was wonderful to share a couple years of work with you. Thanks for being a great colleague and mentor, and congratulations on a great career! Sincerely, Jeff Holmes (Oak Ridge) I am an old friend of Stan's, from his (and my) Rice days.
