We'd walk in the canyons, and we'd often walk with Bethe, and Von Neumann, and Bacher. It was a great pleasure.

The closest to inspiration was my beloved fifth grade teacher, Mrs. Ponti, who I’m delighted lived long enough to get that book’s dedication. I exchanged Christmas cards with her for the rest of her life. She was a wonderful woman. I think the main way she inspired was by respecting students’ interests. She herself knew very little science. Science was not formally taught at all, as far as I can remember, at grade school level. She realized there were a group of us who were interested in science, so she would let us sit by ourselves in the back of the classroom once a week for a couple hours, and she got books for us and discussed science. So I suppose she was a very good model for good students.

I did have — definitely — one heroic figure who impressed me very much indeed, and that was the great Antarctic explorer, Shackleton. Shackleton I always admired because he was a tough man and a very good leader. And whenever he was in difficult circumstances, which he frequently was, he seemed to have the great ability to inspire his men and lead his party safely out of those conditions. So certainly Shackleton, I would have said, more than anything, was a role model for me.

I had really good teachers in high school. Probably I connected the best with an English teacher that I had my junior year in high school, Miss Sanchez, Jan Sanchez — God bless her. I’m still in touch with her, had lunch a couple of years ago, and we email each other and still exchange, recommend books to each other: “What novel are you reading lately? I read this book — you want to read this.” That kind of thing. But she really was the first time — I remember it was in her class that I read The Grapes of Wrath , which was the first time I had read a novel in English where I felt like I got it at the time. I had the, I felt really connected to the writer and to the story. I told her how much I loved that book and what it meant to me, and I think I saw part of my own family, and a lot of the Afghans in that story — people who would, they become uprooted and homeless and kind of drifting around trying to find a new home. So Jan Sanchez was probably my favorite teacher in high school, and although I never shared with her any of my writing, she came to one of my book readings as a surprise. I hadn’t seen her in over two decades, and she showed up, and she goes, “Remember me?” Obviously, I knew immediately who she was, and it made me so proud that she had read my book and she had loved it. I felt like I had done good. You know, when your teacher comes up to you, even if you are middle-aged and have your own family, having your teacher come up to you and pat you on the back is still a pretty special feeling.
