we know the fish, we know the worm, we know the fly, but we don’t know the links between and we don’t know, when we go back to the branches in evolution, we really don’t know what happened there when they branched and how they divert and what is the major drive for evolution.

And in many, many parts of the world, if you’re going to deprive a parent of custody of their child, you better give them a lawyer. And we don’t. We have an unequal representation of people in our court system. And that does, I think, provide an injustice that we don’t pay enough attention to.

They have a lot of extreme physics going on inside them and scientists use them to test theories of relativity on a cosmic scale. Einstein’s theories are checking out pretty well so far.

We can’t delude ourselves into thinking that anything we or any other business does is “sustainable”. The best we can do is minimize the harm we do to the planet. We’ll do what we can to clean up our own house and convince other businesses and suppliers to use cleaner energy and more responsible materials, but it’s a never-ending summit. The work is never done.

The advice that I would give is try to find something that you like. Try to devote your energies to being very good at it. Try to achieve excellence. Don’t necessarily have as a goal success or getting prizes or whatever, but just doing very good work. And work hard. Keep working at it. Be patient. Realize that you don’t always see the benefits of what you’re doing, short-term. But in the end, the activities that I do, for example, scientific research, can be extremely rewarding. It’s really a very fascinating career.

Sherry offered me a list of research options: the one project that intrigued me the most consisted of finding out the environmental fate of certain very inert industrial chemicals – the chlorofluorocarbons (CFCs) – which had been accumulating in the atmosphere and which at that time were thought to have no significant effects on the environment. This project offered me the opportunity to learn a new field – atmospheric chemistry – about which I knew very little; trying to solve a challenging problem appeared to be an excellent way to plunge into a new research area.

For me, it was just a thrill. I just remember thinking at that time, this is the sort of thing I would like to do, if I could. I did not come from a family of scientists. My father was a lawyer, my older brother was a lawyer.

Although my years at Irvine were very productive, I missed not doing experiments myself because of the many responsibilities associated with a faculty position: teaching courses, supervising graduate students, meetings, etc. After spending seven years at Irvine as Assistant and then Associate Professor, I decided to move to a non-academic position. I joined the Molecular Physics and Chemistry Section at the Jet Propulsion Laboratory in 1982. I had a smaller group – only a few postdoctoral fellows – but I also had the luxury of conducting experiments with my own hands, which I enjoyed very much.

I had a number of very good teachers in high school, in fact. Some mathematics teachers that perhaps allowed me the freedom to go beyond the normal routine of the class and to explore some more advanced areas. The same thing happened in college. I was able to communicate with a few of my teachers and professors, and go beyond the normal expectations. And then, as I mentioned before, Professor Pimentel, my mentor for graduate studies, was really influential in terms of the influence that he had for me.

It’s easy to try to exaggerate the problems just to get more attention. So for me, it was very clear that the best way to deal with that was to do the best science that I was capable of doing.
