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.

We're living in a literary age, at least in America, that is marked by a sense of distance, a coolness, in all senses of that word. To be too obviously, unapologetically emotional is to risk being considered foolish, or at the very least not serious.

I credit my parents for many things that had never seemed remarkable when I was growing up, and one of those things is how nonthreatened they were by my constant search for backup parents - other mothers and fathers would have bristled at this, but they never did. So I was always looking for other parental stand-ins, and I always found them.

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 don't have to depend upon your creative work for money, you'll never really have to compromise... Knowing that is hugely liberating as well as artistically clarifying... Being practical about where your money comes from means you can be romantic about your writing... I believe that a healthy society is one that supports its artists, but I also know that that privilege, of being only an artist, is afforded to just a small number. Most of us have to find something else - or live a highly disciplined life, which I'm not willing to do.

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.
