There's a fundamental question that everyone has to answer: What fraction of your life do you spend in service to your fellow man? It's not something that science helps you answer at all. It's one of these questions like, Who are you gong to marry? Science doesn't really help you with the question.
My dad spent most of the '50s and early '60s actually acting as sort of an advance man for the Justice Department, as a civil rights lawyer. So it was actually reading his papers after he passed away a few years ago that first started me thinking about this... What fraction of your life do you spend in service to your fellow man?
Just being able to trade financial commodities is a serious limitation because financial commodities represent only a tiny fraction of the reality of the real commodity exposure picture. We need to be active in the underlying physical commodity markets in order to understand and make prices.
In financial services, the front end of the world operates at super-high speeds: comparative advantages are measured in fractions of nanoseconds. And yet back end processes - the amount of time you have to wait when you sell a stock before cash hits your account - can take days.
As more speed afoot was constantly demanded for big league ball, I noticed the many infield bounders which the runner beat to first only by the thinnest fractions of a second.
Since stepping down as laboratory director in 1999, I have devoted an increasing fraction of my time to international issues. I am involved with energy, environment, and sustainability issues, particularly as they involve new energy sources free of greenhouse gases.
I took my first acting class at age 6 because I found out that's what Carol Burnett was doing - acting. Also she had an imaginary friend as a kid and went to UCLA, two things we have in common. I will always admire her and hope one day, I can make someone laugh a fraction as hard as she's made me bellyache.
