As a citizen, as a public scientist, I can tell you that Einstein essentially overturned a so strongly established paradigm of science, whereas Darwin didn't really overturn a science paradigm.

Only when creative people take ownership of cosmic discovery will society accept science as the cultural activity that it is.

I think we are all the sum of that which has happened in our lives. And if you're successful, it would be wrong to think that you'd be more successful had something been easier. That's not a given.

If you love what you do, you'll be your best at it compared to anything else you might have chosen as a career. Or at least you will love it more, and you won't lead a depressed day of your life.

I don't know why a beauty salon would have a cop's hat and the curling irons are not deadly unless they're still plugged in and they're hot. So I'm not quite sure about that. But I don't know who remembers anymore that you can ignite spray cans, plus there aren't really any spray cans anymore 'cause that was destroying the ozone layer.

They're not selling you one car, you have options. So when I think of space, I think of having options.
