Well, gauge theory is very fundamental to our understanding of physical forces these days. But they are also dependent on a mathematical idea, which has been around for longer than gauge theory has. ↗

In the book, I make the point that here we have string theory and here we have twistor theory and we don't know if either one of them is the right approach to nature. ↗

The basic theory in twistor theory is not to add extra dimensions. ↗

Whether the ice caps melt, or expand - whatever happens - the anthropogenic global warming theorists claim it confirms their theory. A perfect example of a pseudo-science like astrology. ↗

If you ask almost any of them, 'Do you stand behind your theory? Is this the answer?' I think almost everyone would say, 'No, no, no. I'm just trying to expand the range of possibilities.' We really don't know what's going on. ↗

I don't think Obama understands basic economics. Not economics that work. He may understand some theory that someone in Princeton sat and dreamed up, but it's not working. ↗

I studied economics and made it my career for two reasons. The subject was and is intellectually fascinating and challenging, particularly to someone with taste and talent for theoretical reasoning and quantitative analysis. ↗

Theory helps us to bear our ignorance of facts. ↗

Everything that people lob at you who don't know you, it all hurts. When you're doing something as simple as making music, which really, theoretically, shouldn't hurt anyone - I mean, it's a song! Step back for five seconds and laugh. ↗
