“Enzymes are masters of chemistry. They evolved over billions of years to perform specific biological functions. They make complex materials with virtually no waste.”

“Pittsburgh was a wonderful place to grow up - diverse and complex, one could go from one culture to a completely different one in just a few blocks. It was a whole world in one city.”

“Most innovative things are not obvious to other people at the time. You have to believe in yourself. If you've got a good idea, follow it even though others tell you it's not.”

To use the money on a project that makes Britain and the world a far more dangerous place is politically irresponsible and economically obscene.”

“You see billions and billions of stars and recognize that you know some of those have planets, too, and maybe there's life out there, and this is just one of billions of galaxies... and so it gives you this huge perspective of how far we potentially have to go for real exploration.”
