In essence, we string theorists have been trying to work out the score of the universe, the harmonies of the universe, the mathematical vibrations that the strings would play. So musical metaphors have been with us in science since the beginning.

We can certainly go further than cats, but why should it be that our brains are somehow so suited to the universe that our brains will be able to understand the deepest workings?

...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance.

One of the wonders of science is that it is completely universal. It crosses national boundaries with total ease.

Science is the greatest of all adventure stories, one that's been unfolding for thousands of years as we have sought to understand ourselves and our surroundings.

When I give this talk to a physics audience, I remove the quotes from my 'Theorem'.

Nature's patterns sometimes reflect two intertwined features: fundamental physical laws and environmental influences. It's nature's version of nature versus nurture.
