"I don't care much for equations myself. This is partly because it is difficult for me to write them ..." — Stephen Hawking

We lived in a tall, narrow Victorian house, which my parents had bought very cheaply during the war, when everyone thought London was going to be bombed flat. In fact, a V-2 rocket landed a few houses away from ours. I was away with my mother and sister at the time, but my father was in the house.

Many badly needed goals, like fusion and cancer cure, would be achieved much sooner if we invested more.
