Roger Penrose

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

As for morality, well that's all tied up with the question of consciousness.

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.

I would've done anything to work with Satyajit Ray.

I'm a big action junkie. I grew up on the '80s action movies - the bad ones and the good ones.

I use computers and the Internet every day of my life, and yet I have absolutely no idea how they work. I'm like a labrador watching 'The Matrix.'
