Think about the whole world of biological complex sciences. We still don't understand the way a protein folds the way it does.

I do have a concern however, humanity has a great way of adapting and I'm sure scientists of the future, probably after I leave this planet, earth will have a new way of dealing with the internet but I do have a concern in the transition period.

I don't know all the reasons for these achievements, but I know that I love what I do and I have never wanted to rest on my laurels.

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.

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.

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.

I came from Egypt and I owe Egypt a lot to what I am now.
