Randall Munroe, you made my Monday. Possibly my entire week. I give you today's XKCD web comic (and don't neglect to check the mouseover text):
If anybody's wondering "is it kosher for you to put the entire comic in your column rather than a thumbnail and a link to XKCD?" The answer is yes, because Munroe shares most of his work using a Creative Commons Attribution-NonCommercial 2.5 License. That means anybody can reuse the content for noncommercial purposes as long as it's attributed to him.
I can't afford much time to read other people's blogs and comics and whatnot, but I always, always read XKCD. Munroe has also recently started a cool new blog called "What If?" in which he explores the physics of crazy what-if questions. Also genius.
We know you love reading about space exploration, but did you know you can make it happen?
