There are a lot of legislators who are afraid that kids will learn science and lose their faith.

If we wish to draw philosophical conclusions about our own existence, our significance, and the significance of the universe itself, our conclusions should be based on empirical knowledge. A truly open mind means forcing our imaginations to conform to the evidence of reality, and not vice versa, whether or not we like the implications.

I like to say that while antimatter may seem strange, it is strange in the sense that Belgians are strange. They are not really strange; it is just that one rarely meets them.

People are interested in science, but they don't always know they're interested in science, and so I try to find a way to get them interested.

Science has been effective at furthering our understanding of nature because the scientific ethos is based on three key principles: (1) follow the evidence wherever it leads; (2) if one has a theory, one needs to be willing to try to prove it wrong as much as one tries to prove that it is right; (3) the ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.

What science is all about is a process. It's like saying, "Well, is it important for people to know that World War II happened?" Well it's part of what makes us who we are. And so, there's basic bits of science we need to know.

The ultimate goal of physicists is to arrive at an equation that explains everything and could fit on a t-shirt. That may happen but the t-shirt would have to be 10-dimensional.
