The Supernova Song

Su-per nova, su-per nova; Super-no-va over you.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. Don C. has pictures of the young, handsome Professor Woosley,

including some from the early 70's when Stan and other Rice-types

(including me), along with Dave Arnett and Don (both then at Rice)

and Willie Fowler, spent a summer as visitors at the Institute of

Theoretical Astronomy in Cambridge while it was still Fred Hoyle's

territory. I only went one summer, and shared a flat with Stan and

another Rice graduate student. There is a particular picture of the

"Rice mafia" as Fred H. called it, coming out of either the Red

Lion or the Green Man at lunch. (1971 Grantchester, Cambridge)

Stan in his 20's was prone to let his guard down a bit more and be a bit less, well, dignified in those days than the serious scholarly

persona I suppose he maintains today. Indeed, back in his youth, as I recall all too clearly, he was wont to recite, nay, to sing

(if you dare apply that word) -- alas, repeatedly -- part of the lyrics of an Arlo Guthrie song, the refrain to which went more or less :

"Aye doan' want a pickle, jes' wanna ri-ide my mo-ter-sick-el. –

An' Iiiiiii doan' wan-awn-na di-eee, just wanna ri-ide my mo-ter-cy-i."

Usually took a bit of bitters to get him there, which wasn't such a problem then as now.

You might want to ask him about that song. Very suave. It was frequently sung in public,

somewhat unabashedly, often in the locale of a pub or an after-hours balties or kebab joint,

and at least once whilst drinking wine sitting under a bridge by the Cam in the middle of a very

bad downpour which had trapped us there on our way back to the flat on foot from dinner in town.

Fortunately, we'd thoughtfully purchased some wine before departing the source. I reminisce that,

at that juncture, he could just as easily have become a professional vagabond as the accomplished

astrophysicist. An existential point of departure, commemorated by the Pickel Song. In hindsight, I expect it was cheap wine.

You may also wish to inquire whether he has ever, ever, ever again enjoyed a big ol' glass of mead with his chile. (Yes, mead.)

?DEAR STAN:

THIS IS A SPECIAL DAY, ENJOY IT! IT WILL ONLY HAPPEN EVERY SIXTY YEARS.

WHAT IS VERY SPECIAL ABOUT TODAY IS:

1) YOU WILL BE SURROUNDED BY ADMIRERS, RESPECTED COLLEAGUES, DISRESPECTED

COLLEAGUES, COMPETITORS AND A FEW FRIENDS;

2) THESE PEOPLE LOVE YOU IN SPITE OF THE FACT THAT YOU HAVE FILLED ONE

CUBIC METER OF THEIR FILING CABINETS WITH EXCITING AND OBSCURE DOCUMENTS

(PURPORTING TO EXPLAIN SUPERNOVAE) WRITTEN BY

WOOSLEY AND WEAVER,WEAVER AND WOOSLEY. WEASLY AND WOOVER, HEGER AND

WOOSLEY, HOOSLEY AND WEGER AND ON AND ON … … … … … … … … …

3) YOU WILL NOT BE OBLIGED TO PRESENT ANOTHER TALK (THAT IS MORE LIKE A

MOVIE) OF 800 DENSE VIEWGRAPHS OF REMARKABLE COMPLEXITY IN 15 MINUTES;

4) YOU WILL BE OBLIGED TO BE KINDER AND MORE GRACIOUS THAN USUAL---A BIG JOB!!;

5) YOU WILL NOT HEAR ME SING "ROSE OF SAN ANTONIO" IN YOUR HONOR (WHICH I

LEARNED IN BASTROP, TEXAS WHEN YOU WERE ONE YEAR OLD) OR HEAR A SCI-FI

SPEECH BY ME OR SUFFER A ROAST BY ME ALTHOUGH I HAD TAKEN AN OATH TO DO SO.

THE OTHER FIVE SPECIAL FEATURES OF TODAY WILL BE ANNOUNCED LATER THIS YEAR WHEN

YOU WILL BE EXPOSED TO THE DOUBLE JEOPARDY THAT QIAN AND I WILL CITE YOUR PAPERS

AND CLAIM TO BELIEVE IN THEM.

P.S. PLEASE EXCUSE OUR ABSENCE

BUT NAOMI BROKE HER HIP AND WE

HAD TO BOW OUT. WILL TRY TO VISIT

IN NOT TOO DISTANT A TIME.

P.P.S. LUV FROM NAOMI AND ME TO

YOU AND YOUR FAMILY.

There is a house…

Type I’s are still a puzzle.Type II’s are still undone.Our knowledge of exploding starsCould fill a maas and some.

There is a house in Santa Cruz,They call the rising sun.Its been a home to many poor souls, The flame, it never dies.And, God knows, we’re some.

We still hope for a supernovaeIn our galaxy, close by,We had so much fun in the LMCWe’d like another try.

Now mothers, tell your children,

The models tell us this is so,And physics never lies.

Our grandfather was Don Clayton.Tom Weaver was our mum.Old Willy smiles down on us all,Glad that the work gets done

Stan turned to hypernovae –Not violent enough were type II’s.Neutrinos and disks and powerful jetsTo make something that HETE can view.

We need to make some fluorine,So we can brush our teeth.We’re sure that Colgate has an idea,That Stan can work out in brief.

We’ll carry on a-workin’As Stan has always done.And we hope to have as much successAs Stan has clearly won.

With Petra, Willy, and Mandy,He lives there still today,At least for several weeks at a time,Until he next goes away.

Happy B-day from all of us.
