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.

We cant live any more in a world which is based on stuff and not ideas. If you want to live with the world of stuff, were all doomed.

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

I'm a human entropy producer.

In some cases, inventions prohibit innovation because we're so caught up in playing with the technology, we forget about the fact that it was supposed to be important.

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

My biggest worry is I'm running out of time and energy. Thirty years ago I thought 10 years was a really long time.
