The worst thing that ever happened to America was the 19th Amendment.

There is no true understanding of Biology without Chemistry. And there's no true understanding of Chemistry without Physics.

There is a growing awareness that we're losing our technological competitive edge. I think there's an awareness that we're losing our leadership, and that maybe our self image over the past several decades has been a little bit delusional.

Here's what I'm wondering: if, digitally, you can remove red-eye, smooth over wrinkles, make people look thinner, then why don't we have the technology to make me sing better?

I want to create the airplane that flies in the rarified atmosphere of Mars. This is what galvanizes a generation to want to become scientists and engineers in the first place, not we need a scientist to develop a plane that's 20 percent more fuel-efficient than the one your parents flew.

But one of the coolest things about meteorites is that most were formed four-and-a-half-billion years ago, during the birth of our solar system, when, for reasons not yet known, a cloud of gas and dust was transformed into a sun with circling planets.

In modern times, if the sole measure of what’s out there flows from your five senses then a precarious life awaits you.
