There ought to be something very special about the boundary conditions of the universe and what can be more special than that there is no boundary?

Equations are just the boring part of mathematics. I attempt to see things in terms of geometry.

We live in the most probable of all possible worlds.

The downside of my celebrity is that I cannot go anywhere in the world without being recognized. It is not enough for me to wear dark sunglasses and a wig. The wheelchair gives me away.

Time and space are finite in extent, but they don't have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.

So great a contribution to physics was Two New Sciences that scholars have long maintained that the book anticipated Isaac Newton's laws of motion.

I think the universe was spontaneously created out of nothing, according to the laws of science. It has no beginning and no end.
