The universe is so amazing and so limitless, who wouldn't want to study the universe?

There's no greater sign of the failure of the American educational system than the extent to which Americans are distracted by the possibility that Earth might end on December 21, 2012. It's a profound absence of awareness of the laws of physics and how nature works. So they're missing some science classes in their training in high school or in college that would empower them to understand and to judge when someone else is basically just full of it. Science is like an inoculation against charlatans who would have you believe whatever it is they tell you.

Many people feel small because they're small and the universe is big, but I feel big.

When you innovate, you create new industries that then boost your economy. And when you create new industries and that becomes part of your culture, your jobs can't go overseas because no one else has figured out how to do it yet.

(Space programs are) a force operating on educational pipelines that stimulate the formation of scientists, technologists, engineers and mathematicians... They're the ones that make tomorrow come. The foundations of economies... issue forth from investments we make in science and technology.

If humans one day become extinct from a catastrophic collision, there would be no greater tragedy in the history of life in the universe. Not because we lacked the brain power to protect ourselves but because we lacked the foresight. The dominant species that replaces us in post-apocalyptic Earth just might wonder, as they gaze upon our mounted skeletons in their natural history museums, why large headed Homo sapiens fared no better than the proverbially peabrained dinosaurs.

When you advance a frontier and you do tomorrow what's never been done today, you have to innovate to make that happen. You become an innovation culture. When I grew up, every time I turned around it was, "Oh, here's the longest bridge or the deepest tunnel or the fastest airplane." And I originally thought that was just kind of like a pissing contest with men with too much testosterone. And then I realized that to make the tallest building you have to innovate. To make the fastest train you have to design the train in a way that it's never been designed before.
