♦ I believe everyone should have a broad picture of how the universe operates and our place in it. It is a basic human desire. And it also puts our worries in perspective.
♦ Time travel used to be thought of as just science fiction, but Einstein’s general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.
♦ I have noticed even people who claim everything is predestined, and that we can do nothing to change it, look before they cross the road.
♦ We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.
♦ The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C – not much good for defrosting the pizza, let alone cooking it.
♦ I believe in universal health care. And I am not afraid to say so.
♦ Obviously, because of my disability, I need assistance. But I have always tried to overcome the limitations of my condition and lead as full a life as possible. I have traveled the world, from the Antarctic to zero gravity.
♦ Intelligence is the ability to adapt to change.
♦ It is no good getting furious if you get stuck. What I do is keep thinking about the problem but work on something else. Sometimes it is years before I see the way forward. In the case of information loss and black holes, it was 29 years.
♦ Science is not only a disciple of reason but, also, one of romance and passion.
♦ I want to know why the universe exists, why there is something greater than nothing.
♦ Evolution has ensured that our brains just aren’t equipped to visualise 11 dimensions directly. However, from a purely mathematical point of view it’s just as easy to think in 11 dimensions, as it is to think in three or four.
♦ Most sets of values would give rise to universes that, although they might be very beautiful, would contain no one able to wonder at that beauty.
♦ For millions of years, mankind lived just like the animals. Then something happened which unleashed the power of our imaginations, we learned to talk.
♦ My expectations were reduced to zero when I was 21. Everything since then has been a bonus.
♦ Women. They are a complete mystery.
♦ Life would be tragic if it weren’t funny.
