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.

I think I'm a reporter's editor. Being a good reporter is a specific skill, one I admire and don't possess myself - I appreciate people who know how to ask the right questions, who are excellent researchers, who know how to assemble information, and I enjoy working with them to shape their information into an article. Good reporters tend to be receptive to editing, and to a more collaborative form of writing in general, and you always end up learning more from how they work than you expect you will.

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'm not sure a person ever really reveals the whole of himsels or herself to another person, and I'm not sure we should. Or rather, just because you don't, it doesn't mean you can't have a meaningful relationship with another person. It's important to remember that this idea of confessing your most shameful, embarrassing stories and self to someone else as an expression of love and intimacy is a relatively recent phenomenon, and a new definition of what it means to be close to someone. After all, the self is by its nature secretive.

If you start asking how do we make life meaningful and life never ends, then you get into sort of these terrible sort of metaphysical quandaries and it gets really, really bleak looking.

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.

To be a scientist you have to be willing to live with uncertainty for a long time. Research scientists begin with a question and they take a decade or two to find an answer. Then the answer they get may not even answer the question they thought it would. You have to have a supple enough mind to be open to the possibility that the answer sometimes precedes the question itself.
