Science is one of a handful of things that defines us as a very special species. It is amazing how far we have been able to get and how accurate our predictions are. I think understanding how the universe was born is very important. It really gives us a perspective on many things.

It is hard to think of practical applications of the black hole. Because practical applications are so remote, many people assume we should not be interested. But this quest to understand the world is what defines us as human beings.

I'm just focused on exploring new opportunities.

Big Internet companies on average are capable of generating revenue of $1 million per employee, and that compares to 10 to 20 percent of that which is normally generated by traditional offline businesses of comparable size.

Facebook is a platform inside a platform.

The problem is that modern fundamental physics is so far from you and me. The mathematics has become so much more complicated that you need at least 10 years to understand it. Fundamental physics has advanced so far from the understanding of most people that there is really a big disconnect.

Fundamental physics is like an art more or less. It's completely non-practical, and you can't use it for anything. But it's about the universe and how the world came into being. It's very remote from your daily life and mine, and yet it defines us as human beings.
