"You can't just claim that science isn't real when it doesn't align well with your political or financial interests."
At a March 26 hearing of the U.S. House Committee on Science, Space, and Technology, Republican congressmen took turns attacking President Obama's top science advisor, John Holdren. On climate change, their statements became increasingly heated, accu...

You know, retirement planning and investment isn't rocket science nor quantum mechanics... You should apply as much mental rigor to your 401k.
After Waze’s success validated the power of crowd knowledge, a startup called FeeX wants to apply it to a different problem area of our lives -- retirement plans. FeeX, a company aiming to help peo...

Can it be true?  The quantum heat engine has become self-aware and found its own off-switch? "... announcing my second retirement as Chief D-Wave Skeptic...."   Let's see.....
A few days ago, a group of nine authors (Rønnow, Wang, Job, Boixo, Isakov, Wecker, Martinis, Lidar, and Troyer) released their long-awaited arXiv preprint Defining and detecting quantum speedup, which contains the most thorough performance analysis of the D-Wave devices to date, and which seems ...

Sexiest ashtray ever... But really, we have to wait til March now because of the high demand? I'm already dreaming about how fast my code will run...

Any advice out there how I should spec a new macpro to run python code as fast as possible? More cores, or more ram (or solid state hard drive) or more GPUs? I really just run global optimization routines to find Maximum quantum fisher information under decoherence through SciPy and OpenOpt. Variables tend to be 10 - 1000. Already using analytical gradients to speed up search. Would love to utilize multi-threading or parallelization to run multiple searches if that's possible.

Let's play spot the difference in the concepts of two papers. Other than one has 9 authors and the other 2. And one obviously appeared publicly 3 months before the other was submitted... oh, and one suggests that there is some sort of fundamental trade-off between estimating phase and diffusion, whereas the other establishes that there is not (in the optimal case). Cat -> pigeons.

Joint estimation of phase and phase diffusion for quantum metrology

Received 26 September 2014 Accepted 03 March 2014 Published 14 April 2014
Abstract: Coherent ensembles of $N$ qubits present an advantage in quantum phase estimation over separable mixtures, but coherence decay due to classical phase diffusion reduces overall precision. In some contexts, the strength of diffusion may be the parameter of interest.

Thanks Gabriel. Our analysis was for fixed state and measurement, with the trade-off coming from interrogation time. I had wondered about optimal states and measurements. I guess now I don't have to :)

Hatchet job of the year! I miss reading the Sunday Times at home in Ireland. I would always relish the AA Gill reviews. I still remember his description of British soap operas as "a low budget, low brow, lowest common denominator slice of rubbish culture." Must have been before reality TV....

I think we should all try this stuff and write a paper together afterwards. 
Dr. Rick Strassman in his book DMT: the Spirit Molecule, claims that DMT, which is one of the most powerful psychedelic drugs, can provide a reliable and regular access to the other planes of existence.  He claims that DMT may actually be a gateway to parallel universes. In fact, these uni

I'm always a little frightened when the public is allowed to invoke the argument, "It's against Nature" to affect govt policy-- whether they are talking about GM crops or gay marriage. It's like some sort of intellectually lazy self-comforting catch-all. 'Natural' would be for some bigger hairier creature to come along and make you its lunch, and hopefully before you voted.
 
NYTimes: A Lonely Quest for Facts on Genetically Modified Crops

When a bill to ban genetically engineered crops on the island of Hawaii was introduced, doubts nagged at Greggor Ilagan, a councilman, about what the risks were, if any, of the crops.

Plus infinity. Along those lines we recently found "There's a Hair in My Dirt! A Worm's Story" by Gary Larson which is a kids picture book that is all about how we make nature out to be pastoral when the truth is more complicated. Best subversive "kids" book out there.

It would be great if they actually stayed open til 7 as is reported on google. Rather than at 4:57pm the slightly surly boy working there Announces to everyone coming in, sorry guys we are closed....,
