So that's when I saw the DNA model for the first time, in the Cavendish, and that's when I saw that this was it. And in a flash you just knew that this was very fundamental.

I also became interested in chemistry and gradually accumulated enough test tubes and other glassware to do chemical experiments, using small quantities of chemicals purchased from a pharmacy supply house.

In my second year, after moving to the Medical School, I began the courses of Anatomy and Physiology. I had begun to see that I was interested in cells and their functions.

Innovation comes only from an assault on the unknown.
