I understand the arguments about how the billions of dollars spent to put men on the moon could have been used to fight poverty and hunger on Earth. But, look, I'm a scientist who sees inspiration as the ultimate tool for doing good. When you use money to fight poverty, it can be of great value, but too often, you're working at the margins. When you're putting people on the moon, you're inspiring all of us to achieve the maximum of human potential, which is how our greatest problems will eventually be solved. Give yourself permission to dream.

Engineering isn't about perfect solutions; it's about doing the best you can with limited resources.

Just because you're in the driver's seat, doesn't mean you have to run people over.

Never underestimate the importance of having fun. I'm dying and I'm having fun. And I'm going to keep having fun every day because there's no other way to play it.

If we had to vanish tomorrow, what would we want as our legacy?

The best gift an educator can give is to get somebody to become self reflective.
