LRO's First Photos of the Moon
The Lunar Reconnaissance Orbiter (LRO) recently sent back its first photos of the moon, which you can see over at Bad Astronomy. What’s remarkable is how good the resolution on the photos is:
This image, taken in the Mare Nubium region of the Moon, shows a heavily cratered area. The scale here is amazing: the whole image is 1400 meters across, or just under a mile. That’s like looking out your airplane window… if you were over the frakking Moon!
When LRO settles into its final orbit, it will be able to resolve objects only 18 inches across. I can’t wait to see the shots of the Apollo landing sites (which I mentioned earlier).
MIT Hopes to Exorcise ‘Phantom’ Traffic Jams
A really interesting article from Wired about how “phantom” traffic jams, which are without any real cause, form. One of the more amazing parts of the article is how mathematicians use preexisting formulas to solve traffic problems:
The mathematics of such traffic jams are strikingly similar to the equations that describe detonation waves produced by explosions, said Aslan Kasimov, a lecturer in MIT’s Department of Mathematics. Realizing this allowed the reseachers to solve traffic jam equations that were first theorized in the 1950s. The MIT researchers even came up with a name for this kind of gridlock - “jamiton.” It’s a riff on “soliton,” a term used in math and physics to desribe a self-sustaining wave that maintains its shape while moving.
