I’d tell them, “If you believe in something, go for it, but know that when you go for it there’s a price to be paid. Be ready to pay that price and you can contribute to the welfare of society, and society will acknowledge you and respect you for it. And don’t be afraid. Don’t be afraid.”

Getting rich slow isn't actually slower. It's slower in year one, but it might be faster in year seven.

Sensitivity. Be sensitive in every way possible about everything in life. Be sensitive. Insensitivity brings indifference and nothing is worse than indifference. Indifference makes that person dead before the person dies.

They encouraged me, the way I do others now, that if you really have something that you like to do, that’s what you probably should do. Despite what everybody says, that you can’t make a living, or that’s not practical, or a thousand reasons why you may not do this or this or this. If that’s what your heart says you should do, chances are that you ought to listen.

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.

As I was starting my academic career, it was almost considered to be a negative signal to your career to get involved in politics ... But to me that was a sign you were doing something useful.

So achievement, to me, is something that just comes with this attitude of doing your work the best you can in a passionate way. It’s not something that you have to expect. It’s something that’s a consequence of what you do, but it’s certainly important.

I did. As a kid, I liked music. I still like it a lot of course. I used to play the violin. I did contemplate, well, maybe that’s an option. I could become a musician. Somehow my parents got some advice that unless I was willing to spend eight or 10 hours a day just playing the violin that I should just give it up. To me, that was very bad advice because you could of course, get very involved in music without being a musician. Fortunately, even though I gave up eventually playing the violin myself, I never gave up my fondness for music. But if I had a chance again, I would not give it up. I would just do it as a hobby. I think that was just because I did not get the correct advice.

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.

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.
