Chinook at night, with a photobomb by the Andromeda Galaxy!

College is not trade school. Who’s really complaining? The people really who are pissed off are the 22- and 23-year-olds who thought were going to get out of school and get some swell job and now have to figure out where to get it. It’s spoiled brats who thought they bought their ticket. It’s an absurd one-to-one expectation to think that a college degree guarantees a job. That’s not the reality anymore, and it hasn’t been for a long while.


Red Sox to sign Mark Prior.

Jon Heyman tweets “#redsox signing mark prior. cant hurt. once great. rooting for him to come back.”

I think his use of “can’t hurt” is a subtle mockery of Mark Prior’s career.

Yeah, I’ll take a ticket for that train, thanks!


Check out this - blue! - Martian sunset

What explains the weird coloration - blue at the center, rosy pink at the edges - of this picture of a sunset? Well, first of all, it wasn’t snapped on this planet; it was taken by the Spirit Martian rover in 2005, at the Gusev crater. For the science behind the colors, read this excerpt by Robert Krulwich:

Sunshine, as you know, contains many different wavelengths of light. If you catch a beam of light in a prism (Newton did this) it breaks into a rainbow of colors — reds, violets, blues. When the sunshine on Mars hits the clouds of fine dust floating through the air, it also breaks into different colors. Martian dust is exactly the right size to absorb the blue wavelengths of light and scatter red wavelengths all over the sky. That’s why if you are standing on Mars and look away from the setting sun, most of the sky is rosy, pink, and various shades of red.

But now look straight at the setting sun. On Mars, the beams of light streaming toward you, having lost their red waves, show the wavelengths that haven’t scattered off. That remaining light is predominantly blue. So when you look straight at the sun on Mars, you see a haze of blue. Look away from the sun, and the light is red.
