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.

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 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.

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.

When I give a lecture on Egypt there are thousands of people in the lecture hall, so obviously they would like to go to science and they would love to do science, but you really have to get the correct science base in order for them to interact.

You should have some time to think and that's very important.
