I belonged to a small minority of boys who were lacking in physical strength and athletic prowess. ... We found our refuge in science. ... We learned that science is a revenge of victims against oppressors, that science is a territory of freedom and friendship in the midst of tyranny and hatred.

The average student emerges at the end of the Ph.D. program, already middle-aged, overspecialized, poorly prepared for the world outside, and almost unemployable except in a narrow area of specialization. Large numbers of students for whom the program is inappropriate are trapped in it, because the Ph.D. has become a union card required for entry into the scientific job market.

The Ph.D. system was designed for a job in academics. And it works really well if you really want to be an academic, and the system actually works quite well. So for people who have the gift and like to go spend their lives as scholars, it's fine. But the trouble is that it's become a kind of a meal ticket - you can't get a job if you don't have a Ph.D.

The world is just - it's wonderful when you look at all the detail. It's just amazing. Nothing is boring if you look at it carefully.

Theory said one thing and the experiment said something different, so that was the stimulus that started me going, that there was something there to be explained, which wasn't understood and to try to see why that experiment gave the answer it did, so it was a big opportunity for a young student starting to have actually an experiment which contradicted the theory, so that's was my chance to understand that.

That's, of course, the beautiful thing about science - that it's all about things we don't understand, not just the things we do understand.

People who travel in China tell me that the mood there is still very upbeat, because their media is different from our media. Chinese media emphasize how well things are going and suppress the bad news and publish the good news.
