I met my wife Anne who was a sociology student, and her influence together with activities associated with the student movement of the time opened up my interests amongst other things into the theatre, art, music, politics and philosophy.

Like many students, I found the drudgery of real experiments and the slowness of progress a complete shock, and at my low points I contemplated other alternative careers including study of the philosophy or sociology of science.

Scientific understanding is often beautiful, a profoundly aesthetic experience which gives pleasure not unlike the reading of a great poem.

My main efforts focussed on trying to identify the rate controlling steps during the cell cycle. Crucial for this analysis were wee mutants that were advanced prematurely through the cell cycle and so divided at a reduced cell size.

During the winter my attention was attracted to the changes in the stars and planets in the sky.

Therefore, I reasoned that study of the cell cycle responsible for the reproduction of cells was important and might even be illuminating about the nature of life.

Ever since Sir Isaac Newton's times, scientists have worked in the same sort of way: They show a great respect for experiment and observation, They don't cherry pick data, They take a skeptical approach to what they do. And then scientists work together to get a consensus as to what should be believed And that generates very reliable knowledge and that reliable knowledge drives innovation
