Benasque 2009
I’ve never made it to Benasque, and am always profoundly jealous of those who have gone:
Dear Colleague,
We are pleased to inform you that following a very successful editions of Benasque 1998, 2000, 2003, 2005, and 2007, we are organizing another workshop of the similar type in June 2009. This is to invite you to apply using the electronic form that you can find on the website specified below. We encourage you to apply as soon as possible and not later than the end of March 2009. The number of participants at the Benasque Centre at any given time is limited to about 50. We will do our best to accommodate most of the applicants,however, in some cases we may be unable to find suitable time slots for all of them, i.e. we cannot guarantee acceptance.
Budget permitting, we expect to offer a modest allowance to some participants. Preference will be given to those staying for the whole duration of the workshop.
We do hope to see you in Benasque!
Ignacio Cirac and Artur Ekert

Physics World Article
For subscribers to Physics World, an article I wrote The Race to Build a Quantum Computer has appeared in the February edition. Unfortunately unless you have a subscription you’ll have to pay to read the article…or better yet, pick up a copy of the magazine!

What do you do when your industry is shifting under your feet? Taking the lead with radical steps is one strategy. The New York Times did just that this afternoon when it announced that it has released a new Application Programming Interface (API) offering every article the paper has written since 1981, 2.8 million articles. The API includes 28 searchable fields and updated content every hour.

Different meanings of Bayesian statistics – Statistical Modeling, Causal Inference, and Social Science1. Surprising results from conditional probability. For example, if you test positive for a disease with a 1% prevalence rate, and the test is 95% effective, that you probably don't have the disease.
2. Bayesian data analysis as a way to solve statistical problems. For example, the classic partial-pooling examples of Lindley, Novick, Efron, Morris, Rubin, etc.
3. Bayesian inference as a way to include prior information in statistical analysis.
4. Bayes or Bayes-like rules for decision analysis and inference in computer science, for example identifying spam.
5. Bayesian inference as coherent reasoning, following the principles of Von Neumann, Keynes, Savage, etc.
6. [added at Larry's suggestion; see comments] Bayesian inference as a method of coming up with classical statistical estimators. -
"A new startup company is in the works at the University of Washington, based on inexpensive, portable solar cells that could go far beyond the standard rooftop model. Conventional solar cells are made from expensive silicon, but the UW group, led by materials science and engineering professor Alex Jen, has come up with a way to harness solar energy using thin polymer film–akin to really thin cling wrap"

"Yes, they were real. No, they didn't carry malaria. And they definitely didn't qualify as a swarm. But they sure did get a lot of attention.
That's the word from a reliable source after the Microsoft chairman set the tech world, ahem, abuzz by opening a jar of mosquitos at the TED conference today — reportedly telling the crowd that not only poor people should experience the problem. We made a few calls and found out that the jar contained a relatively modest collection of mosquitoes: more than a few, but probably fewer than ten." -

As Comet Lulin moves into the northern sky in mid February to rise around midnight, it should at least be spotted by comet watchers with binoculars and a good sky chart. Tracking observations indicate that the comet officially designated C/2007 N3 (Lulin) has now swung by the Sun and is approaching Earth on a trajectory that will bring it within half the Earth-Sun distance in late February.

SciRate Page For 0902.0402In this work we describe how a single artificial multi-level Cooper Pair Box molecule, interacting with a superconducting microwave coplanar waveguide resonator, when suitably driven, can generate extremely large optical nonlinearities at microwave frequencies, with no associated absorption.
The World is Such a Wonderful Place
The view from my plane window this afternoon (thank you United Airlines for making me take this Delta Airlines flight):
Check out those lenticular clouds!
One of my fondest memories was on a trip with my father to the Sacramento in a small plane, and on the trip back falling asleep and waking up with spectacular Mt. Shasta right, and I mean right, outside the window.

"We document widespread changes to the historical I/B/E/S analyst stock recommendations database. Across seven I/B/E/S downloads, obtained between 2000 and 2007, we find that between 6,580 (1.6%) and 97,582 (21.7%) of matched observations are different from one download to the next. The changes include alterations of recommendations, additions and deletions of records, and removal of analyst names." Got clean data?

"When they analyzed these data-200 million of them-in exactly the same fashion that Bachelier had analyzed data almost a century earlier, they made a startling discovery. The pdf of price changes was not Gaussian plus outliers, as previously believed. Rather, all the data-including data previously termed outliers-conformed to a single pdf encompassing both everyday fluctuations and “once in a century” fluctuations. Instead of a Gaussian or some correction to a Gaussian, they found a power law pdf with exponent -4, a sufficiently large exponent that the difference from a Gaussian is not huge"

"In a paper appearing in Physical Review A, Panos Aliferis, who is at the IBM Watson Research Center, and John Preskill of the California Institute of Technology, rigorously establish a lower bound for the fault-tolerance threshold for one of Knill’s constructions that has relatively small overhead requirements. Their results indicate that fault-tolerant computation should definitely be possible with this scheme, if the error probability per logical operation does not exceed 0.1%."

"One intriguing idea getting shuttled around President Obama’s inner circle could end up pouring significant cash into the innovation hubs of Seattle and Boston. This idea, hatched at the Brookings Institution in Washington D.C., calls for building a national network of two dozen or more centers of excellence in cleantech R&D, with annual budgets of as much as $200 million from competitive research grants, to jumpstart innovation in alternative energy."

"As we reported last week, Woodman is the Microsoft solutions adviser who got a tattoo of the company's unofficial "Blue Monster" logo last year, only to find himself among the 1,400 people laid off by the company Jan. 22. Some Microsoft critics commenting on our post and on BoingBoing questioned Woodman's judgment for getting the tattoo.
Here's the remarkable part: In a follow-up post, Woodman not only speaks glowingly about Microsoft but he goes out of his way to defend the past actions that helped shape its reputation. " -
