You should chose your heroes a-la carte. Picking and choosing from one and then another, thereby assembling a kind of composite hero. That way when you discover something reprehensible about any one of them it matters nothing to you because that's not the part of them that piqued your interest.

Science is not a subject you took in school. It's life. We are wrapped by it, in it, with it.

NASA was invented as a response to Cold War steps. There are those who presumed that we went to the moon because we're explorers. We went to the moon because we were at war with the Soviet Union. And so when it became clear that they (Soviet Union) were not going to the moon, we're done with the moon.

We need more science in the world. Train me.

Need a distraction today? Not only does 12 + 1 = 11 + 2, but the letters "twelve plus one" rearrange to give you "eleven plus two."

In America, there are people who don't read science fiction but still think about tomorrow, so it's not only the force of science-fiction that makes you a tomorrow thinker.

The caricature of science is that we hold tight to the theories we have, and shun challenges to them. That's just not true. In fact, we hold our highest rewards for those scientists who can prove others wrong. And by the way, they are famous in their own lifetimes. We don't wait until they're dead.
