I don't want to think about how many people have thought or still think that I'm crazy.

As we move towards 8 or 10 billion people on the planet, there's a little less gold per capita. Each one of us will continue to be fighting over an ever smaller percentage of total resources. This is not a happy thought

Tell me it's never been done. Because the only real laws in this world-the only things we really know-are the two postulates of relativity, the three laws of Newton, the four laws of thermodynamics, and Maxwell's equation-no, scratch that, the only things we really know are Maxwell's equations, the three laws of Newton, the two postulates of relativity, and the periodic table. That's all we know that's true. All the rest are man's laws

Education, actual learning - it is hard work. It's very personal. Your parents don't teach you anything. Your teachers don't teach you anything. The government doesn't teach you anything. You read it. You don't understand it; you read it again. You break a pencil and read it again.
