My advice to other disabled people would be, concentrate on things your disability doesn't prevent you doing well, and don't regret the things it interferes with. Don't be disabled in spirit, as well as physically.

Religion believes in miracles, but these aren't compatible with science.

No one undertakes research in physics with the intention of winning a prize. It is the joy of discovering something no one knew before.

The progress of the human race in understanding the universe has established a small corner of order in an increasingly disordered universe.

The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load.

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

There should be a better way to start a day than waking up every morning.
