I have generally had few setbacks and few obstacles. I have been very fortunate in that things have been handed to me rather than my going out after them. There are a few roads that I didn’t take that I maybe could have. When I was a graduate student, maybe a second-year graduate student, I worked frequently at the Illinois State Library in Springfield, and one day, the director of that library called me into his office and said, “I have some news to tell you that is still very hush-hush, but I’m resigning from this job. I’m going to the Chicago Historical Society, and I’m going to recommend that you be appointed in my place.

The hard part was getting around this, this was a religion among physicists, and in fact even in the Bohr-Einstein debates, and with Schrödinger also, the universal religion was quantum mechanics makes correct predictions, period, no, off the table. What Bell's theorem and in particular our version of it, the Clauser-Horne-Shimony-Holt experimental prediction, showed that either that had to be wrong, nor Einstein's whole legacy had to be wrong. I think at the time people who were critical of doing the experiment didn't realise really what was at stake, that it was that cut and dried between two religious icons, if you will, the field of physics. Since I kind of was the inventor of the CHSH inequality and the CH inequality and all that, I knew exactly what it was all about. But it took a long time for that to filter in.

What I’ve got doesn’t hurt. I’ve been lucky. The treatment has been benign. I don’t know if I could concentrate if I was in pain. I’ve never had to stop.

According to Egyptian regulations, the chairman of the department, the dean of the faculty of sciences, the president of Alexandria University, and the minister of higher education, they all have to sign off.

How people need the possibility of sharing, of not being alone. It’s bad to be poor, but it’s difficult to be alone.

And with that film, I was proud because I decided the woman should not say what she feels but documentary images would speak for her.

I remember meeting the photographer Brassaï. I was a young photographer. He said, “Take your time, look at things. Look carefully.” I liked the idea that it’s not the act; it’s what you have in mind before you take a picture.

Poverty in the world. Injustice.

I was curious. Curiosity is a good thing. And I was curious about different people. And, as I said, I waited until something was strong enough to disturb me or inspire me to make a film.

I would like to be remembered as a film-maker [who] enjoyed life, including pain. This is such a terrible world, but I keep the idea that every day should be interesting. What happens in my days – working, meeting people, listening – convinces me that it’s worth being alive.
