The largest newspaper in the United States is only reaching 1 percent of population. We are kind of assuming that 'Wall Street Journal,' 'USA Today,' and other newspapers are very important. Yes, they're extremely important, but only to 1 percent of the population on a daily basis.

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.

Google never knew how successful key words would be. Facebook didn't know how successful Zynga would be.

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.

I think top scientists need to be compensated at a different scale in society. Somebody with experience will tell you that true scientists are not motivated by money - they are motivated by the quest itself. That is true. But I think an additional recognition will not hurt.

I have this ratio that if you divide age of entrepreneur by market cap of company. For Facebook it's one. Every year of his life Zuckerberg has been making $1 billion for investors.

Kai-Fu's Innovation Works is the top very-early-stage fund in China. We are proud to be an investor, and hope that IW will help to produce in China companies on the scale of Facebook, Zynga, or Groupon.

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.

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.

You have to travel globally today to know what's going on and maintain an edge.

There is huge demand for artificial intelligence technologies.

Facebook didn't know how successful Zynga would be.

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.

Facebook is a platform inside a platform.

I have invested in four social networks. More than any other. But that's in Russia and Poland.

I'm trying to learn from various corners of the world.

Google never knew how successful key words would be.

We've only made three investments: Facebook, Groupon, and Zynga.

One of the companies that we've invested in is called Facebook. In only two years, between 2009 and 2011, the information exchanged between people increased 28 times. And that cannot be explained by new people joining Facebook.
