Hangouts with Chess
I was walking in the park today and I saw those cool chessboard tables and I figured it would be nice to be able to replicate the experience over hangouts, especially with the cold weather coming so I made a virtual chessboard you can play with over hangouts. Thanks +Bobbi Jo Woods and +matthew rappaport for helping me test. You can find the chessboard here:

Feel free to make yourself a copy and have fun playing 1 on 1 or crowd sourcing your next move ;)

PS If the pieces are everywhere restore to the first revision and you'll have a board ready to go!

JPMorgan Chase recently donated an unprecedented $4.6 million to the New York City Police Foundation.

The gift was the largest in the history of the foundation and will enable the New York City Police Department to strengthen security in the Big Apple.

A great shot of the Northern Lights by Omar Smith, I think it'd be a shoe in for the Royal Observatory's Astronomy competition's Earth and Space category. Check out his flickr page for more amazing photos ;)

Finding another Earth is the biggest goal of exoplanetary astronomy right now (besides trying to find a cooler name than "exoplanetary astronomy", which you can't, because it's so damn cool). We've made amazing strides toward that goal, and I strongly suspect the first one will be found in observations made by NASA's Kepler observatory.

Part of that search will involve trying to figure out how many planets like Earth (in size and mass) are out there to begin with. An astronomer, examining Kepler data, has come up with a number: he has calculated that as many as 1/3 of all Sun-like stars in the galaxy have Earth-sized planets orbiting them at the right distance to support life.

In the post linked below I go over how he figured that out, and mention one or two places where his calculations may be off. But the end result is that his fraction of 1/3 matches other, independent calculations. We may actually be converging on knowledge of just how many other warm, wet Earths are out there, orbiting alien stars. And the number may very well be in the billions.
