we know the fish, we know the worm, we know the fly, but we don’t know the links between and we don’t know, when we go back to the branches in evolution, we really don’t know what happened there when they branched and how they divert and what is the major drive for evolution.

They have a lot of extreme physics going on inside them and scientists use them to test theories of relativity on a cosmic scale. Einstein’s theories are checking out pretty well so far.

we can select one gene out of those 20,000 genes, and completely destroy that one particular gene so that we can understand the function of that particular gene. I got very interested in that technology. It was 1992 or 1993 when I graduated from my Ph.D. school. So I decided to study — I decided to learn about knockout mouse technology. But at that time in Japan, only a few scientists were working on knockout mouse technology

We still have a long way to go, we still have many obstacles and many challenges to face. It’s far from perfect, and it may never be, but I think as long as we do the best we can to improve conditions, then people will be benefited.

I have a lot of respect and admiration for President Carter. It was a delight when I got the Nobel Peace Prize to get a letter from him. It meant a lot to me, getting that letter from a man who is my idol in many ways. ... He always has the courage to express his views, his convictions. He doesn’t hesitate to run against the current. He has always had a moral certitude. He looks at the ethics and morality of his action, and that’s key. Whatever we do in life, whether privately or publicly, we need to have a compass. We need to be sure that what we do is not only good for us, but good for the people at large. That’s ethics. That’s morality. I think we need to always know that our work is not just good for us in the short term, but it’s morally correct. And when I talk about morality, I don’t talk about religion. I talk about a moral code, a moral value, which I think we all have, being honest, being fair, being correct. These are values I think we all share.

I think it’s more modeling. I never bring in my children and say, “Listen, these are the values you should follow in life.” I think it’s a modeling by my wife and me. I think we give them a good life. They saw how we go through life: a difficult time, a hard time, good time. I am very happy. I think they are good kids. If I have hope, it’s because I look at my children.

One of my mentors, Tom Frank, a professor of law at NYU, he was really instrumental in making me understand that we need to look at the global picture, and we always need to not take anything for granted, but go very much through a process of critical thinking before we formulate our views. So he was, I think, instrumental in shaping my views as to how to pursue my career in the future.

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.

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.

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.
