It seems to me that we must make a distinction between what is "objective" and what is "measurable" in discussing the question of physical reality, according to quantum mechanics. The state-vector of a system is, indeed, not measurable , in… — 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
