Now on ScienceBlogs: Rhodes Secretary: Wall Street Megabonuses Draining Our Young Talent
Speculations on astronomy, astrophysics, news I find interesting, theoretical issues, science and science policy. I will digress into computational physics, science fiction and general issues and basically whatever I feel like whenever. And, of course, cats.
Still working on an analytic exact approximate solution to the herding problem.
So you want to be an astrophysicist?
Random info.

There is a radical proposal in Iceland to restore the economy and rescue the nation from bankruptcy: expand the tax base to recover revenue from the extensive underground economy.

Ethan at Starts With A Bang did a nice post the other day on an old chestnut - why you can't touch your toes if you're backed against a wall.

Hubble multicycle large proposals were due today...
Julianne tests the conjecture of proposal number invariance under simple scaling.
Looks to be annoyingly close to correct with about 40 proposals in by the deadline.
I still think we need to check the proposal success probability as a function of proposal rank number.

Yup, the LCROSS crash did kick up some water.
NASA shows proof.

A couple of years ago, a group of California theorists came up with a whacky theory for a new kind of thermonuclear supernova.
It would be just like regular type Ia supernovae, but fainter and faster, and a bit more mixed up, as evidenced by its new label: the 0.Ia supernova, a perfect mallogos of a neologism.
So now someone had to go and find one, with plenty more to come.
