There is nothing bigger or older than the universe.

Gravity is so strong that space is bent round onto itself, making it rather like the surface of the earth. If one keeps traveling in a certain direction on the surface of the earth, one never comes up against an impassable barrier or falls over the edge, but eventually comes back to where one started.

Perhaps we could write code to optimize code, then run that code through the code optimizer?

Someone told me that each equation I included in my book would halve the sales. I did put in one equation, Einstein's famous equation, E = MC squared. I hope that this will not scare off half of my potential readers.

The moment you understand the whole Universe, is the moment you slightly begin to understand the way God's mind works

The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.

We are in danger of destroying ourselves by our greed and stupidity. We cannot remain looking inwards at ourselves on a small and increasingly polluted and overcrowded planet.
