Amen. I've long thought that probability should be a basic part of high school mathematics; it's far more relevant to the typical person's life than, say, trigonometry is.
Supermassive Black Hole Is Thrown Out of Galaxy 167
DarkKnightRadick writes "An undergrad student at the University of Utrecht, Marianne Heida, has found evidence of a supermassive black hole being tossed out of its galaxy. According to the article, the black hole — which has a mass equivalent to one billion suns — is possibly the culmination of two galaxies merging (or colliding, depending on how you like to look at it) and their black holes merging, creating one supermassive beast. The black hole was found using the Chandra Source Catalog (from the Chandra X-Ray Observatory). The direction of the expulsion is also possibly indicative of the direction of rotation of the two black holes as they circled each other before merging."

Actually, no.
The moon is lumpy and thus doesn't have a uniform gravity field. Objects in low orbits are slightly perturbed and don't take very long to hit the surface.
An object high enough to make the Mascons not matter is also high enough that Earth perturbs its orbit, and again, takes a short time (months, usually) to either get pulled completely out of orbit or hit the surface.
There are no stable orbits around the moon.
In Defense of the Classic Controller 251
Kotaku has an opinion piece by Leigh Alexander singing the praises of classic, button-rich controllers for the level of precision and complexity they offer. While the Wii Remote and upcoming motion-control offerings from Microsoft and Sony are generating a lot of interest, there will always be games for which more traditional input devices are better suited. Quoting:
"With all this talk about new audiences — and the tech designed to serve them — it's easy to get excited. It's also easy to feel a little lost in the shuffle. For gamers who've been there since before anyone cared about making games 'for everyone,' having that object in our hands was more than a way to access the game world — it was half the appeal. Anyone who's ever pulled off a chain of combos in a console fighter can tell you about the joy of expertise and control. ... Gamers may suffer some kind of identity crisis as the familiar markers of their beloved niche evolve — or disappear entirely. The solution to that one's easy: Get over it. Like it or not, it's clear that gaming's not a 'niche' anymore, and its shape will change. The more pressing issue is whether or not controller-less gaming will truly make the medium richer. Making something 'more accessible' doesn't necessarily make it better."
