OMG, We're All Going to Die!

But not because of this.
Movie Theaters Will Fry Us All with Infrared to Stop Pirates
Fry us all? Oh, please.
Sharp, at the request of Japan’s National Institute of Informatics, has developed a method to ruin the camcorder footage shot by pirates in movie theaters. By placing mega IR lights behind the screen (which are invisible to the human eye, of course), the light can tunnel through tiny holes that are already in screens for the passage of sound.
CCDs are sensitive to IR, which is why there is usually a filter in place (unless you remove it). But the filter isn’t perfect, so adding more IR should screw up the picture. Until someone figures out that they can put another (perhaps better) IR filter on the lens. Oh, crap, did I say that out loud?
Bonus picture (I know Matt did this already, but I finally had my camera at a place with an electric stove). The burner was still black to the naked eye when this image was recorded.

The Onion: Nadir Of Western Civilization To Be Reached This Friday At 3:32 P.M.
Experts predict that the penultimate catastrophe will occur at approximately 7:15 p.m. Thursday night, when the social networking tool Twitter will be used to communicate a series of ideas so banal they will instantaneously negate the three centuries of the Renaissance.

As I hurtled down the highway, a pair of golden arches crept over the horizon, and the proverbial lightbulb smacked me in the forehead. To gauge the creep of cookie-cutter commercialism, there’s no better barometer than McDonald’s – ubiquitous fast food chain and inaugural megacorporate colonizer of small towns nationwide.

Many more in the included links.
This does not include* any mention of the vendor gift index; Tuesday’s Lab Snacks included mini Lorna Dunes. They were tasty. (He who opens the package gets first choice). And it was a partial order, so possibly more to come.
*UPDATE: Now it does. I’ve been linked to by Kottke!

What causes the colors of metals like gold?
If an energy level (like the 3d band) holds many more electrons (than other energy levels) then the excitation of electrons from this highly occupied level to above the Fermi level will become quite important. Gold fulfills all the requirements for an intense absorption of light with energy of 2.3 eV (from the 3d band to above the Fermi level). The color we see is yellow, as the corresponding wavelengths are re-emitted. Copper has a strong absorption at a slightly lower energy, with orange being most strongly absorbed and re-emitted. In silver, the absorption peak lies in the ultraviolet region, at about 4 eV. As a result, silver maintains high reflectivity evenly across the visible spectrum, and we see it as a pure white. The lower energies (which in this case contain energies corresponding to the entire visible spectrum of color) are equally absorbed and re-emitted.

To give it its full mathematical description, a Gömböc is a three-dimensional, convex and homogeneous object with exactly one stable point of equilibrium and one unstable point of equilibrium. Requiring it to be homogeneous amounts to saying that you’re not allowed to cheat: the material from which the Gömböc is made has to be uniform throughout, so you’re not allowed to use weights, as those found in roly-poly toys, or other irregularities to get the Gömböc to self-right. Convexity means that the Gömböc is not allowed to bulge inwards, in other words, the straight line connecting any two points on the Gömböc has to lie entirely within the Gömböc. It’s easy to create a non-convex shape with one stable and one unstable equilibrium point, hence the restriction to convexity.
I have this mental image of Dieter describing the Gömböc. I don’t know why.
Your three-dimensional, convex homogeneity has grown tiresome. Now is the time on Sprockets vhen ve dance!

175 Times. And Then the Catastrophe.
The laws of thermodynamics, unfortunately, have no regard for human life at all. They cannot be brushed off or bargained with, and if you do not pay attention to them they can cut you down.

Stone Age satnav: Did ancient man use 5,000-year-old travel chart to navigate across Britain
When did a chart become satellite navigation?
It’s considered to be one of the more recent innovations to help the hapless traveller.
But the satnav system may not be as modern as we think.
On the contrary. I think the satnav system is precisely as old as we think.
He analysed 1,500 prehistoric sites in England and Wales and was able to connect all of them to at least two other sites using isosceles triangles – these are triangles with two sides the same length.
This, he says, is proof that the landmarks were deliberately created as navigational aides. Many were built within sight of each other and provided a simple way to get from A to B.
Or, settlements were quasi-equally spaced, as the terrain allowed, because most people making a new settlement probably wouldn’t choose a site too close to an existing settlement, for fear of conflict.
Mr Brooks added: ‘The sides of some of the triangles are over 100 miles across, yet the distances are accurate to within 100 metres. You cannot do that by chance.
I wouldn’t be at all surprised if you could. Given the kind of packing restrictions present, I’d bet a semi-random distribution of sites would yield many such triangles.
