Thursday, March 14, 2013

Today is March 14, or "3/14," the first three digits of Pi. It's a day celebrated around the (geek) world as "Pi Day." Pi, of course, is the ratio of the circumference to the diameter of a circle. It was first recorded by Archimedes, but you can replicate his discovery ...

Monday, March 11, 2013

Here are some of the things Reza Farazmand knows. He knows how we dream.

He knows how we hurt ...

He knows how little we know.

Guy Builds Solar-Powered Death Ray In His Backyard (Yawn)

Saturday, March 09, 2013

Aatish, a guy I follow on Twitter, tosses this stuff off like it's no biggie, but that's because he's a physics grad student. He knows things I don't know. And because I don't know them, what he finds mildly amusing makes me gasp. Really.

Here's an example. He mentions ...

What Happened When Humans Met An 'Alien' Intelligence? Sex Happened

Friday, March 08, 2013

We have dreamed about it for so long. We've told stories, made movies, imagined what it would be like when we humans have our first "close encounter" with an intelligent alien, a creature about our size, who can gaze back, talk (even if we can't understand what's being said) who ...

What happened to the future? In the '60s and '70s, says astrophysicist Neil Tyson, kids thought about going to space, exploring; tomorrow seemed so, so near. But no longer. Our worl...

Before we get to today's topic (flower blooming), let's take a Sloth Break. I know this isn't usual, but hey, I think everybody should see this adorable baby sloth named Matty giving his human caretaker, Claire, a flower. If you've already seen it, jump ahead to my essay. But if ...

Thursday, February 28, 2013

My pal Erik Olsen at The New York Times has just described an extraordinary new way to look at people. You point a camera at someone, record the image and then, using an "amplifier," you can discover things you've never seen before.
