We see the universe the way it is because we exist.

I am damned if I'm going to die before I have unraveled more of the universe

There are grounds for cautious optimism that we may now be near the end ofthe search for the ultimate laws of nature.

Because there is a law such as gravity, the Universe can and will create itself from nothing.

Then we shall... be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason - for then we would know the mind of God.

The fact that no one understands you doesn't mean you're an artist.

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.
