No doubt, the most challenging class of questions in science is the origin of things.

If Mars formed life, then life on Earth could have been seeded by life on Mars, making every life form on Earth descended from Martians.

Let's invent a new tomorrow and then make it happen. Let's invent the city of tomorrow, the home of tomorrow, the transportation of tomorrow.

The day we stop exploring is the day we commit ourselves to live in a stagnant world, devoid of curiosity, empty of dreams.

Companies want to innovate. Companies that don't innovate wither on the vine. The connection between STEM fields (science, technology, engineering, and mathematics) and the financial stability of a nation is what needs to established.

I'm revealing information to people. I'm not creating it. And to the extent that people embrace it, I think they're empowered by it, because any time you have a bigger perspective today than you did yesterday, it's got to be only for the good of your mind, your body, your soul.

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.
