In August I spoke at the Chautauqua Institution as part of their celebration of Darwin and Linnaeus. I posted the written version of my talk back then, but I’ve just received the audio recording and thought some folks might prefer listening to it instead. I actually prefer it too, because whenever I give talks, I look at what I’ve written and revise it as I talk. You can listen to the talk right here on the handy Odeo player I’ve embedded at the bottom of the post. Or you can download it to listen offline.

Nicole write: “I got it 6 years ago when I was a freshman in college, starting a double major in physics and astronomy. I was drawn to the colorful and artistic interpretation of a binary star. Maybe one day I’ll find the film picture of when it was first taken. Today I’m a grad student in astronomy, contemplating a second tattoo!”

The National Academy of Sciences has a survey they’d like people to fill out to help them figure out what kinds of educational materials about science, engineering, and medicine they should publish in print and on the web.

I just took it, and can assure you it’s quick and painless. And along the way they pointed me to some pdf’s that look helpful.

Update: In case my linking above wasn’t clear, here’s the survey

Attention, lovers of science: clear your 2009 calendar.

The Coalition On The Public Understanding of Science (COPUS), a grassroots network, is putting together a massive celebration of science stretching across all 12 months of the year. Museums, scientific societies, and other groups will be presenting lectures, science cafes, special blogs, exhibits, and the occasional Banana Slug String Band concert. Every month will have a theme, from evolution (February, the month of Darwin’s birthday) to astronomy (July, in celebration of the 400th anniversary of the summer Galileo first trained his telescope to the sky). And if you want to join the happening, COPUS wants to hear from you.

Whenever I lose my watch, I take my sweet time to get a new one. I savor the freedom from my compulsion to carve my days into minute-size fragments. But my liberty has its limits. Even if I get rid of the clock strapped to my wrist, I cannot escape the one in my head. The human brain keeps time, from the flicker of milliseconds to the languorous unfurling of hours and days and years. It’s the product of hundreds of millions of years of evolution.

Keeping track of time is essential for perceiving what’s happening around us and responding to it. In order to tell where a voice is coming from, we time how long it takes for the sound to reach both ears. And when we respond to the voice by speaking ourselves, we need precise timing to make ourselves understood.
