Of death, my father has always said that the best conditions are the ones in which you have plenty of time to prepare - to say what you need to say; to arrange your estate - and the ones in which you get to choose, or at least have some knowledge of, how and when it might happen. One can't elude death, but one can have a good death.

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.

I know I'm a better editor than I was when I began, twenty years ago. I'm less scared of the text, I'm less scared of the writer, and, crucially, I no longer believe that I have to leave my mark on every story.

I always wanted to be a scientist. I don't really have any writer friends. The process of being a writer is much more interior than being a scientist, because science is so reactionary. I think that all research scientists think of themselves as belonging to a grand tradition, building on work that has been worked on since the very beginning of science itself. Whereas I'm not sure writers think of themselves in the same way.

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 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.
