The dinosaurs never saw that asteroid coming. What's our excuse?

I object to religion in science classrooms not because it's religion but because it's not science.

Any time scientists disagree, it's because we have insufficient data. Then we can agree on what kind of data to get; we get the data; and the data solves the problem. Either I'm right, or you're right, or we're both wrong. And we move on. That kind of conflict resolution does not exist in politics or religion.

Science literacy is a vaccine against the charlatans of the world that would exploit your ignorance.

One should not be too distracted by definitions. Ideas transcend definitions.

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.

If you seek only easy problems to solve, then ultimately, there'll be nothing about you to distinguish yourself from others.
