There is huge demand for artificial intelligence technologies.

Facebook is at the forefront. It's the company that can fundamentally change the way information is being exchanged and processed. It can be the basis for artificial intelligence to develop over time.

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.

Facebook can be an accumulation of different intelligences. Ask a question, translated into many languages and somebody, somewhere in the world, will have an answer.

Exploring is an innate part of being human. We're all explorers when we're born. Unfortunately, it seems to get drummed out of many of us as we get older, but it's there, I think, in all of us. And for me that moment of discovery is just so thrilling, on any level, that I think anybody that's experienced it is pretty quickly addicted to it.

Influenced by him, and probably even more so by my brother Theodore (a year older than me), I soon became interested in biology and developed a respect for the importance of science and the scientific method.

Choosing my career was always based on job satisfaction rather than financial security. I wanted to get a job in science; I enjoyed being a surgeon and I now enjoy being an academic and having a media career.

For science must breathe the oxygen of freedom.
