The universe and the Laws of Physics seem to have been specifically designed for us. If any one of about 40 physical qualities had more than slightly different values, life as we know it could not exist: Either atoms would not be stable, or they wouldn't combine into molecules, or the stars wouldn't form heavier elements, or the universe would collapse before life could develop, and so on...

The universe doesn't allow perfection.

The universe is governed by science. But science tells us that we can't solve the equations, directly in the abstract.

I don't have much positive to say about motor neuron disease, but it taught me not to pity myself because others were worse off, and to get on with what I still could do. I'm happier now than before I developed the condition.

Among physicists, I'm respected I hope.

Sometimes I wonder if I'm as famous for my wheelchair and disabilities as I am for my discoveries.

In effect, we have redefined the task of science to be the discovery of laws that will enable us to predict events up to the limits set by the uncertainty principle.
