Some broad themes brought me where I am today. At a very young age, my hobby became thinking and finding connections.

What really makes it an invention is that someone decides not to change the solution to a known problem, but to change the question.

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

I think we have a society which is spending more and more of its money on healthcare as a percent of GDP as a percent of a lot of things. I think that's a measure of success.

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

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

We are in a race between knowledge and catastrophe. If we keep track of what is important, never lower our standards or forget why we are here, we have the ability to determine the fate of the world.
