While physics and mathematics may tell us how the universe began, they are not much use in predicting human behavior because there are far too many equations to solve. I'm no better than anyone else at understanding what makes people tick, particularly women.

There is no prescribed route to follow to arrive at a new idea. You have to make the intuitive leap.

Science is not only a disciple of reason but, also, one of romance and passion.

If aliens visit us, the outcome would be much as when Columbus landed in America, which didn't turn out well for the Native Americans.

I believe that the long-term future of the human race must be space and that it represents an important life insurance for our future survival, as it could prevent the disappearance of humanity by colonizing other planets.

Only a very few would allow creatures like us to exist. Thus our presence selects out from this vast array only those universes that are compatible with our existence. Although we are puny and insignificant on the scale of the cosmos, this makes us in a sense the lords of creation.

We got through all of Genesis and part of Exodus before I left. One of the main things I learned from this exercise was not to begin a sentence with "And." When I pointed out that most sentences in the Bible began with "And," I was told that English had changed since the time of King James. In that case, I argued, why make us read the Bible? But it was in vain. Robert Graves at that time was very keen on the symbolism and mysticism in the Bible.
