There was an interesting article in yesterday's NYT about Bill Nye (the science guy!) and how he's gone from science booster to science advocate—and what the difference is. (Though he's still very booster-y.) Here's an excerpt:

[Young people] have gone from watching him explain magnetism and electricity to defending the scientific evidence for climate change, the age of the earth and other issues they have seen polemicized for religious, political and even economic reasons.

He takes on those who would demand that the public schools teach alternative theories of evolution and the origins of the earth — most famously, in a video clip from the site that has been viewed some five million times. In it, he flatly tells adult viewers that “if you want to deny evolution and live in your world — in your world that’s completely inconsistent with everything we observe in the universe — that’s fine. But don’t make your kids do it, because we need them. We need scientifically literate voters and taxpayers for the future.”

Read the whole thing here—and let's be sure to ring him up the next time we have a debate on fluoride. He may be the only person we'd all listen to.
