In my late teenage years, I began to think, well now I have to get serious. The world is a serious place and this is kid's stuff and now I have to find a real job, and I didn't know and I played with the idea of being an engineer. I didn't know what that meant but Sputnik had just been launched and the world was saying, there must be engineers in the world and so, okay, I'll be an engineer. The... I thought of an architect. I don't know, really, what that entailed but that seems to be a respectable thing and maybe I'll be an architect. And somehow, the roulette wheel of these things ended up and I thought, I'll be an oceanographer. I don't know where that came from but it got me and the university that I went to, one of the reasons I chose that university, Johns Hopkins in Baltimore was that they had an oceanography department. So I arrived there, as an 18-year-old and they said, 'Well, what do you want to do?' And I said, 'I want to be an oceanographer' and the admissions person said, 'Well, yes, we have a graduate department in oceanography, but there is no undergraduate. So you have to... like medical school, you have to take a kind of version of pre-med for this and there are two divisions in oceanography. There's biological oceanography and geological oceanography. What do you want?' Well, I had biology in high school so I thought, well, I'll try geology. So I signed up for that program and I enjoyed it but I didn't really enjoy it.
