Truffaut, Rohmer, Claude Chabrol, they were the great directors of the Nouvelle Vague. They found the freedom to make exactly the films they wanted. Chabrol was important because he was able to make very strong portraits of women and very complex portraits of women. He was very clever and he had a lot of joy and pleasure. He didn’t have some big theories about his work, he just enjoyed making films. I try to work like that.

I did think about Woody Allen’s movies with Frances Ha because Woody Allen’s movies were also in black and white and very contemporary. Manhattan and Stardust Memories are not period pictures. Particularly in Manhattan you have the grandeur of the black and white and the Gershwin music sort of playing up against a more intimate storyline in which, when you break it down, is really just people sleeping with each other and trying to figure out their lives. But something about the filmmaking and the approach to it makes it feel almost epic. And, ultimately, the concerns of those people are epic. That movie is a masterpiece.

When I was in high school, there was a book by James MacGregor Burns, a wonderful historian, called The Lion and the Fox, about FDR. And it was about his personality, his character, his early years in Hyde Park, his polio experience and… I remember that so vividly as the first real, live history book that I love so much. And I later met him, and have gotten to know him as a colleague, and he’s about 30 years older than I am, and I couldn’t wait to tell him, “You were the one who made it happen.

One was Roscoe Gilkey Dickinson. He had got his doctorate in physical chemistry — x-ray crystallography — in 1920. He was the first person to get a Ph.D. from California Institute of Technology. And he was continuing with x-ray crystallography, determining the structure of inorganic crystals. After I had accepted appointment as a graduate student at California Institute of Technology, A.A. Noyes, the head of the division of chemistry and chemical engineering, wrote to say that he had decided I should work with Roscoe Dickinson on determining the structure of crystals. This was really extremely fortunate for me, in my opinion. I don’t think that there was any field that was more suited to my interests, and I don’t really know why Dr. Noyes selected me out of eight or ten new graduate students to do x-ray crystallography. Dickinson had a remarkable mind. He was a very careful investigator and thinker, a very logical thinker. When he was teaching me x-ray crystallography, he also taught me to ask at each stage in the argument, “What assumptions are being made? How reliable is the conclusion that you draw? What chance is there that one of the assumptions you have made is not correct?” “You should recognize,” he said to me, “that there is in almost every investigation a lack of complete rigor. You should understand just how reliable the arguments are that you are presenting.

I think that is the most important lesson you learn in life, that you have to be ready to make a compromise. You do not compromise your principles, but you have to be ready to compromise. You have to understand that you cannot get your way 100 percent. Life is too complicated. You are not an island, and you work in a social setting, and you need to understand that you work always — at the family level, at the society level — to work out the compromise that is perceived to be fair. You don’t get 100 percent of what you want, but at least you will get the basic minimum that you require.

No. Unfortunately, it hasn’t worked out quite that way. At that time, everybody was euphoric that we will have a new world order, you know, a world order that does not rely on nuclear weapons, nuclear deterrence. Unfortunately, it didn’t work that way. ... We still have thousands of warheads in existence. We still have more than 20 — 30 countries relying on nuclear deterrence for their own survival.

Unfortunately, I don’t. My wife now reads fiction. I don’t have the time to read fiction. My wife reads the fiction and summarizes it to me, but I wish at one point I’ll have time again to read fiction. It is a luxury I cannot afford right now.

My father was a lawyer. My mother was a homemaker. My father was president of the Egyptian Bar Association. He was involved very much during the Nasser era — which was one of the most repressive eras in Egyptian history — in fighting for democracy, fighting for human rights, and I think that to a lot of extent shaped my view as to what I wanted to do in the future. I wanted to have a world where people are free to express their views, to have freedom of worship, to have freedom from want, and I saw poverty in Egypt when I grew up. To me, freedom, in the larger sense — to be able to speak, to worship, free from want, free from fear — I think it was a key as to what I thought I would like to do when I grow up.

My sister-in-law and I are working towards the same goal, through different paths: the security of the human family.

Well, many. I think Steinbeck, for example, was one of my favorites, Somerset Maugham, Hemingway. Quite a few.
