Every atom in your body came from a star that exploded. And the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: you are all stardust.

You couldn't be here if stars hadn't exploded, because the elements - the carbon, nitrogen, oxygen, iron, all the things that matter for evolution - weren't created at the beginning of time. They were created in the nuclear furnaces of stars, and the only way they could get into your body is if the stars were kind enough to explode. So, forget Jesus. The stars died so that you could be here today.

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

Neutrinos alone, among all the known particles, have ethereal properties that are striking and romantic enough both to have inspired a poem by John Updike and to have sent teams of scientists deep underground for 50 years to build huge science-fiction-like contraptions to unravel their mysteries.

We live at a very special time . . . the only time when we can observationally verify that we live at a very special time!

Celebrate our brief moment in the sun

What people believe impacts on what they do. And it's not as if religion is universally bad. Of course it's responsible for many peoples doing good actions.
