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.

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.

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.

Syria is the proud heir of an ancient civilization that has a unique spectrum of minorities that encompasses Muslims and Christians of various denominations. There are at least ten such ethnic and religious groups.

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 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.
