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.

People think of these eureka moments and my feeling is that they tend to be little things, a little realisation and then a little realisation built on that.

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.'

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