Progress in science depends on new techniques, new discoveries and new ideas, probably in that order.

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.

The modern computer hovers between the obsolescent and the nonexistent.

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.

Living most of the time in a world created mostly in one's head, does not make for an easy passage in the real world.

Innovation comes only from an assault on the unknown.

I completed the first three years of primary school in one year and was admitted to the local school the age of six directly into the fourth year, some two years younger than all my contemporaries.
