"I’m a Professor of Mathematics at the University of Oxford but a few years ago I took over from Richard Dawkins as the Professor for the Public Understanding of Science. The title always makes me laugh a little bit because I think everyone expects I must know the whole of science and here I am to explain it to you all. But it got me thinking, certainly no scientists must know it all but maybe there might come a point when science knows everything about the universe. Maybe we could answer all the great unsolved problems about the universe."
