The magic words 'on the Internet,' if inserted into nearly any sentence, seem to protect it from normal critical scrutiny.

Another random thing I do is the search for extraterrestrial intelligence, or SETI. And you may be familiar with the movie 'Contact,' which sort of popularized that. It turns out there are real people who go out and search for extraterrestrials in a very scientific way.

Many of the things the slow food people honor were innovations within historical times. Somebody had to be the first European to eat a tomato.

With cult foods, there is an underlying assumption that the best cooking ideas came generations ago. Yet culinary innovation is nothing to be ashamed of. When a chef tells me he is cooking with his grandmother's recipe, I always wonder why. Did talent skip the past two generations?

Until I was 16, I read nothing but science fiction. I loved William Gibson and I still do. But my favourite book when I was growing up, for a long time, was 'Snow Crash' by Neal Stephenson, which I must have read about a dozen times when I was a teenager.

In the lab, we're discovering that nature can do chemistry we never dreamed was possible.

Just because you put super great musicians together, it doesn't mean you're going to have that chemistry as a band.

When I got to MIT, I discovered a really interesting Master's program called the Science and Technology and Policy Program - it taught people with a background in STEM how to think about science and tech from a policy perspective. It was a great way to understand how to communicate science to a policymaker or a layperson.
