Wellwellwell! I don't know how I have to complain, since I could not yet read the full article, but I'm sure I will :-).

It's funny to see how people get more and more humble in the desperate attempt to save their stupid ideas... At the beginning was the brave and bold aim to cloak something in free space (in a sphere or a cylinder). This requires inhomogeneous, anisotropic, magnetic materials; hopeless!! So one reduces to one polarization, now we have inhomogenous, anisotropic materials; still hopeless! At this point one downgraded the pretension: instead of cloaking in free space, we make a "carpet cloak" and hide an object behind an invisible dent in a mirror. But if that shall be continuous, we still need inhomogeneity and this is very hard. So now instead of a dent we take a cone and then it is claimed to work ... for ONE polarization. But of course the cloak can't work at all incident angles... irony of fate: everything is now made from birefringent media, the antithesis of what the metamaterials dogma was at the beginning!

Hi Luzi, can you please send me the paper. We are writing a project based on sulfates and carbonates, and all this BS sounds great for the introduction (The authors used Calcite as birefringent material)

"collective wisdom" to define what a "galaxy" is. Is it really a good approach ? It does not seem any sociologist is involved in the process. http://arxiv.org/PS_cache/arxiv/pdf/1101/1101.3309v1.pdf

You needed models to create the intricate network of bonds based on the homeowners’ payments, models to predict prepayment rates, and models to predict defaults. You needed the Internet to sail these bonds back and forth across the world, massaging their content to fit an investor’s needs at a moment’s notice. Add to all this the complacency, greed, entitlement, and callous stupidity that characterized banks in post-2001 America, and you have a recipe for disaster.

Well, I have to quote one of the 21st century classics on this one: "I'm sorry mr Musk I can't hear you because of all the Latin chanting. In the meanwhile can you hand me another goat to drain? I'm quite behind on my blood pentagram drawing" - Paul N., AD 2014.

given that they apparently can't decide between two moral options (probably such as humans), should we be more concerned about their stupidity or their intelligence http://arxiv.org/abs/1411.2842

I personally don't even trust people to make "moral" choices in conditions of warfare. History is way too full of examples.
