An evening pause: I especially like the trick where you pick up a penny from the bottom of a dish filled with water, without getting wet.
New computer simulations suggest that the spiral arms of galaxies are not only a natural phenomenon but that they are a persistent one.
The day of reckoning looms: An audit of California’s fiscal state has found it to be $127 billion in the red.
Were California’s state government a business, it would be a candidate for insolvency with a negative net worth of $127.2 billion, according to an annual financial report issued by State Auditor Elaine Howle and the Bureau of State Audits. The report, which covers the fiscal year ending June 30, 2012, says that the state’s negative status — all of its assets minus all of its liabilities — increased that year, largely because it spent more than it received in revenue.

None of this is a surprise. California voters chose Jerry Brown and the Democrats to lead them into more debt.
Astronomers watch the central supermassive black hole of a galaxy eat something, either a planet or a brown dwarf.
Astronomers were using Integral to study a different galaxy when they noticed a bright X-ray flare coming from another location in the same wide field-of-view. Using XMM-Newton, the origin was confirmed as NGC 4845, a galaxy never before detected at high energies. Along with Swift and MAXI, the emission was traced from its maximum in January 2011, when the galaxy brightened by a factor of a thousand, and then as it subsided over the course of the year. “The observation was completely unexpected, from a galaxy that has been quiet for at least 20–30 years,” says Marek Nikolajuk of the University of Bialystok, Poland, lead author of the paper in Astronomy & Astrophysics.
By analysing the characteristics of the flare, the astronomers could determine that the emission came from a halo of material around the galaxy’s central black hole as it tore apart and fed on an object of 14–30 Jupiter masses. This size range corresponds to brown dwarfs, substellar objects that are not massive enough to fuse hydrogen in their core and ignite as stars. However, the authors note that it could have had an even lower mass, just a few times that of Jupiter, placing it in the range of gas-giant planets.

An evening pause: An apropos song I think for April Fools. That’s Stephen Sondheim on the piano, accompanying Bernadette Peters.
James Hansen is retiring from NASA and will dedicate his time to global warming activism.
All that is really changing is that Hansen will no longer work for the government. The activism has been going on for a very long time.
Also, it is interesting how this New York Times article seems very unaware of this fact, which makes all of Hansen’s global warming claims very suspect. Might the Times not want the public to know this annoying detail?
Does this make you feel safer, or more free? Since 2011 Homeland Security has been claiming that it has the authority to inspect private safety deposit boxes without warrants.
Are your indoor tomato plants probable cause for an armed raid?
Yes, if it was up to most police departments and governments today.
