When I was a child, I thought of my Delta town as the center of the universe, but now I realize how little I know about the universe. As a child, I thought I was immortal, but now I recognize how limited a time we all have. As a child, success meant scoring A on every exam, but now I take it to mean good health, close family and friends, achieve- ments in my work, and helping others.

I thought in my Nobel Lecture I pointed that I was delighted that the Swedish Academy of Science did not quote anything about my current work right now, because the current work that my group is focusing on is actually both the time resolve electrons and possibly x-rays to be able to get the architecture of these molecules, the molecular structures themselves, of very complex biological systems. That's the ultimate goal.

Human resources are just tremendous in Egypt but we need the science base.

There are many, many books I've read and I think this is quite naïve actually because we all just try to uncover something. But the universe at large is full of questions that we still don't know anything about and there will be always young people brilliant who are going to make new discoveries.

I built on the efforts of a previous scientist, others will build on the work I'm doing and if I look at the whole scope from chemistry to biology to physics, it's just the list is too long to mention just one and it's not fair to the others.

There is a danger one has to really be knowing much more because you can't be too narrow on science.

When they called me with the Nobel call from Secretary General of the Swedish Academy it was twenty minutes to six and he said well that was well hope I'm not disturbing you but I am the Secretary General of the Swedish Academy. Of course you can imagine I was frozen in time when he said that but then he made a very famous statement, something to the effect that this is the last 20 minutes of peace of your life.
