As soon as I got set up at Princeton, which in those days was really easy and you didn't have starting grants. You used the department microscopes, which were excellent. You used the department balances, which were primitive. And chemicals mostly were available, but if they weren't, they ordered them for you. And so I guess my attitude then, and starting up again was, I've got to…  I've got to just wallow in the developmental aspects of slime molds and see what I see. So I had this feeling that I knew it was chemotaxis but there were so many other things. What makes it so that some cells turn into spores, and some cells turn into stalk cells, and etc, etc? So there's this tremendous number of interesting biological questions which they need answering. So I dove in. After about a year or so, I got a grant from the NSF. The NSF had just started up and I got a grant from the NSF. And they wrote to me and said, please write us a letter at the end of your progress report. So I wrote them a letter. And the letter said, well, things didn't really work out too well this year. We tried this, and it didn't work. And we tried that, and it didn't work, and that was more or less my report. I got this priceless reply, which said, don't worry about it. That's the way research goes sometimes. And I continue to think that it's too bad we lost that.

[Q] It's changed?

Yes, you're just always are boasting about what you've done.
