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. — Roger Penrose Copy Share Image
As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on. — Roger Penrose Copy Share Image
Ordinary photons do have spin, they have a notion of helicity so they spin around their direction on motion. — Roger Penrose Copy Share Image
My father himself was a human geneticist who was recognized for demonstrating that older mothers tend to get more Down syndrome children, but he… — Roger Penrose Copy Share Image
A computational device is incapable of developing a mind. We got consciousness not just by being clever. — Roger Penrose Copy Share Image
It is hard to see how one could begin to develop a quantum-theoretical description of brain action when one might well have to regard… — Roger Penrose Copy Share Image
It may well be there is something else going on in the brain that we don't have an inkling of at the moment. — Roger Penrose Copy Share Image
As for morality, well that's all tied up with the question of consciousness. — Roger Penrose Copy Share Image
I used to make polyhedra with my father. There were no clear lines between games and toys for children and his professional work. — Roger Penrose Copy Share Image
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… — Roger Penrose Copy Share Image
Some people take the view that we happen by accident. I think that there is something much deeper, of which we have very little… — Roger Penrose Copy Share Image
My older brother is a distinguished theoretical physicist, a fellow of the Royal Society. — Roger Penrose Copy Share Image
