Look up at the stars, not down at your feet.
I’m not religious in the normal sense. I believe the universe is governed by the laws of science. The laws may have been decreed by God, but God does not intervene to break the laws.
I think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We’ve created life in our own image.
One cannot really argue with a mathematical theorem.
It would be very difficult to explain why the universe should have begun in just this way, except as the act of a God who intended to create beings like us.
One does not have to appeal to God to set the initial conditions for the creation of the universe, but if one does He would have to act through the laws of physics.
The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.
Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.
We should seek the greatest value of our action.
The human failing I would most like to correct is aggression. It may have had survival advantage in caveman days, to get more food, territory or partner with whom to reproduce, but now it threatens to destroy us all.
Science is beautiful when it makes simple explanations of phenomena or connections between different observations.
Not to take this web of dualities as a sign we are on the right track would be a bit like believing that God put fossils into the rocks in order to mislead Darwin about the evolution of life.
The downside of my celebrity is that I cannot go anywhere in the world without being recognized. It is not enough for me to wear dark sunglasses and a wig. The wheelchair gives me away.
Government works best under the glare of public scrutiny. Absent such scrutiny, abuses occur.
Science is not only a disciple of reason but also one of romance and passion.
Time and space are finite in extent, but they don’t have any boundary or edge. They would be like the surface of the earth, but with two more dimensions.
Before we understand science, it is natural to believe that God created the universe. But now science offers a more convincing explanation.
Scientists have become the bearers of the torch of discovery in our quest for knowledge.
I believe in universal health care. And I am not afraid to say so.
There are no black holes – in the sense of regimes from which light can’t escape to infinity. There are however apparent horizons which persist for a period of time.
