Now, almost twenty years since my last job in book publishing, I know that there are far more socially inept people in book than in magazine publishing. At the time, however, I just didn't feel I was enough: smart enough, savvy enough, well read enough, educated enough, charming enough. Much of this was probably because I was very naive, and didn't really know how to behave in an office. This made me a terrible assistant, which in turn made me a terrible junior book editor.

My father collected turtles when he was young. My parent's wedding album, there's two pictures of them getting married and the rest are just pictures of turtles. I remember they had Galapagos tortoises that they had somehow imported illegally and a bunch of other turtles too. I like the animals themselves. They're so self-possessed and self-contained and there's something wise and mysterious about them. I also like that they are prehistoric animals.

I was fortunate to be at that school in an era in which encounters between students and teachers were encouraged; there were a number of teachers who lived on campus, and they'd regularly invite students over for dinner on the weekends. I hope it's still like that: being treated seriously by an adult you admire is a great gift. Children, like adults, want respect - but it's only when you're older that you realize how few people actually extend it.

I have one friend to whom I've told more than I've ever told anyone, and yet there are significant territories I have and will never let him access - in large part because I'm trying to protect him, and one of the responsibilities of loving someone is protecting him or her, even if who you're protecting them from is yourself.

When you're young, your perception of what it means to be a writer is often less about the writing and more about what seems to be the accompanying life: speeches and travel and hanging out with other writers. You think that when you get published, your life will clarify itself to you somehow. But when you don't get published until you're middle-aged you know who you are already, and your life expands to make room for your writing, rather than orbiting around it. You realize that there's no one way to be a writer, and that the job is less of an identity and more of a vocation.

I wanted to write about the time when science became modern, around the 1950s. Right after physicist J. Robert Oppenheimer, science started being so politicized and used as such a political weapon. When my father, who is a scientist, tells me about those years, I get a competing portrait of people who were expected to behave normally and be decent respectable members of society and who were also allowed this freedom to think in big and expansive ways. Now, when you think about people who work in labs, they're allowed to be socially inept in a very fundamental way.

Witing is essentially interior work, and many writers are interior personalities. Having a job forces you out of the world of your work, and into the one in which you get to observe people. Yes, you can imagine all this, but as a fiction writer, you can never observe enough the rhythms of how humans move through the world. A job demands that you structure your time much more carefully. You learn how to be resourceful, and that in turn provides a certain intensity of focus.
