I am not one of the new media experts working all the time with my computers and the PowerPoint's and things of that sort. So, I'm an old fashioned still in this regard but these are the moment where I really can be creative, if I am, to be left alone with just a book and piece of paper and to be thinking.

Everybody thinks some times that science is done as a master plan and that somebody like me came from Mars and figured out everything and so on, but that's really not the way it worked.

Scientists contribute in a variety of ways and I don't think I can singular one even including [Albert] Einstein, that I can say that he's the best. We don't work like the best basketball player and the best musician and so on. Science is a collective effort.

If you like, there is a Guinness time. The reason for that it's fundamental. It is not that we have to keep shortening the time. It turns out all molecular and biological systems have speeds of the atoms move inside them, the fastest possible speeds are determined by their molecular vibrations and this speeds is about a kilometre per second.

For me to sit down here, even as a Nobel Laureate and make a prediction about which science I think that will be a mistake.

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

Although the Nasser revolution of 1952 was secular, the culture remained deeply religious - but it was a faith of moderation and tolerance. Women made up nearly half my class at university, and my senior academic adviser there was a woman. In Alexandria, my friends were Christians and Muslims.
