I have so much that I want to do. I hate wasting time.

To my mathematical brain, the numbers alone make thinking about aliens perfectly rational.

Jesus loves you, but everyone else thinks you're an ass.

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.

If I have questions about the universe on my mind when I go to bed, I can't turn off. I dream equations all night.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

Many people find the universe confusing - it's not.
