As three laws were good enough for Newton, I have modestly decided to stop there. The only way to discover the limits of the possible is to go beyond them into the impossible. If there were no hazards there would be no acheivement, no sense of adventure. Few great men remain great when one gets up close to them. Dust moving at 50 kilometres a second can get through a surprising thickness of metal.

It is very difficult not to feel a certain affection towards someone who likes you. No Utopia can ever give satisfaction to everyone.
