We must develop as quickly as possible technologies that make possible a direct connection between brain and computer, so that artificial brains contribute to human intelligence rather than opposing it.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.

I think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

Why are we here? Where do we come from? Traditionally, these are questions for philosophy, but philosophy is dead.

Sometimes, I get afraid it has defined me, that sense of grief, loss and illness. But actually, it is about allowing myself to take hold and say: 'This is part of who I am, but not only who I am.'

My father was a Japanese prisoner of war, a survivor of the Thai-Burma Death Railway, built by a quarter of a million slave labourers in 1943. Between 100,000 and 200,000 died.
