Everybody remembers numbers and computers remember numbers. People remember procedures and computers certainly remember procedures. But the other thing that's still important is that your perception as a human is affected subtly by all this stuff that you can't quite articulate.

All of your memories affect everything you do whereas with a computer, there's adaptive software and things, but it's more literal.

I meet so many people who are intimidated by arithmetic.

I hope climate science becomes the big thing. And then what I want is electrical engineers to solve the world's energy problems, energy distribution problems. I want mechanical engineers to make better transportation systems. I want chemical engineers to develop better solar panels, and so on.

The Big Bang banged, and for some reason we’re here. And that’s astonishing. And that we can understand that, that’s the most astonishing.

I feel that I've often pointed out that there are countless aspects of life and nature that scientists and scientific thinkers cannot explain.
