Material With Negative Refractive Index Created
holy_calamity writes "The race to build a material with a negative index of refraction for visible light has been won by researchers in Germany. The advance could lead to super-lenses able to see details finer then the wavelength of visible light, or the previously predicted invisibility cloak for visible light." From the article: "[The researcher] determined the refractive index of the material by measuring the 'phase velocity' of light as it passed through. His measurements show the structure has a negative refractive index of -0.6 for light with a wavelength of 780 nm [the far red end of the visible light spectrum]. This value drops to zero at 760 nm and 800 nm, and becomes positive at longer and shorter wavelengths."
Now that this has been invented, can we get a patch for Sneak King?

Thank you sincerely very much for your informative reply [informative in contrast to the some or all other replies, everything is very likely relative to something else, as you obviously suspect]. You should be rewarded with lots of +1, up to the total maximum of +5, but I think you'll appreciate my thanks far more than the total score given by thousands of slashdot idiots. Not to mention that this score is capped to a maximum of +5, which may cause a feeling of under appreciated. Or perhaps not, there is no way to know. I'am terrible sorry to have no relevant information to return. This is because I am (1) only interested in this subject and (2) by far not an expert. At the moment I can only think of one bit of information that might - or might not - be usefull to you: "Smoking sigars is healthier than smoking sigarettes". [which might be due to (Although "due to" is now a generally acceptable synonym for "because," "due to the fact that" is a clumsy and wordy substitute that should be avoided in formal writing. "Due to" is often misspelled "do to.") the fact I am currently smoking a sigar].
I suspect that some selective breeding many, many years ago resulted in the higher than average IQ that people of German descent seem to possess. Unfortunately some negative traits were also passed along. For example, my father's side of the family is 100% German. Many of the descendents of my great-great-grandfather are very intelligent, but about 3/4 of them have inherited a serious hearing defect.
I'd love to see a study comparing the average IQ's of people from various ancestries.
