A great commentary on generic TV commentary. Who else but the BBC would do this?

"Video: A new way to unfold the Earth's surface produces a new kind of map A new technique for unpeeling the Earth's skin and displaying it on a flat surface provides a fresh perspective on geography, making it possible to create maps that string out the continents for easy comparison, or lump together the world's oceans into one huge mass of water surrounded by coastlines. See a gallery of the new maps "Myriahedral projection" was developed by Jack van Wijk, a computer scientist at the Eindhoven University of Technology in the Netherlands. "The basic idea is surprisingly simple," says van Wijk. His algorithms divide the globe's surface into small polygons that are unfolded into a flat map, just as a cube can be unfolded into six squares. Cartographers have tried this trick before; van Wijk's innovation is to up the number of polygons from just a few to thousands. He has coined the word "myriahedral" to describe it, a combination of "myriad" with "polyhedron", the name for polygonal 3D shapes. Warping reality The mathematical impossibility of flattening the surface of a sphere has long troubled mapmakers. "Consider peeling an orange and trying to flatten it out," says van Wijk. "The surface has to distort or crack." Some solutions distort the size of the continents while roughly preserving their shape - the familiar Mercator projection, for instance, makes Europe and North America disproportionately large compared with Africa. Others, like the Peters projection, keep landmasses at the correct relative sizes, at the expense of warping their shapes. An ideal map would combine the best properties of both, but that is only possible by inserting gaps into the Earth's surface, resulting in a map with confusing interruptions. Van Wijk's method makes it possible to direct those cuts in a way that minimises such confusion. Maps of significance When generating a map he assigns a "weighting" to each edge on the polyhedron to signal its importance, influencing the pl

Grand Khan Guyuk In a letter dated 1246 from Grand Khan Guyuk, pictured, to Pope Innocent IV, Genghis Khan's grandson demands that the Pontiff travel to central Asia in person Vatican Archives Although scholars have had access to the secret archives since 1881, they remain closed to the general public The Holy See's archives contain scrolls, parchments and leather-bound volumes with correspondence dating back more than 1,000 years.

Some have called it the car that will save General Motors: the Chevy Volt, a plug-in electric sedan set to launch in three test markets (in California, Michigan, and the Washington, D.C., area) by the end of 2010. GM's Chevy brand was one of the charter sponsors of this week's South by Southwest Interactive Festival in Austin, Texas, and it brought a Volt along for the ride. Why, exactly? The 12,000 SXSWi attendees, most of whom are all about the latest high-tech craze, are exactly the people Chevy thinks will want a Volt.

bwahhahaaah---psuedo-science concepts distilled into chemistry symbols. i want a building block set made with these for the next generation of budding scientists.

"It's a hoax," said coal company CEO Don Blankenship, "because clearly anyone that says that they know what the temperature of the Earth is going to be in 2020 or 2030 needs to be put in an asylum because they don't." On the other side of the debate was environmentalist Robert Kennedy, Jr. "Ninety-eight percent of the research climatologists in the world say that global warming is real, that its impacts are going to be catastrophic," he argued. "There are 2 percent who disagree with that. I have a choice of believing the 98 percent or the 2 percent." To social scientist and lawyer Don Braman, it's not surprising that two people can disagree so strongly over science. Braman is on the faculty at George Washington University and part of The Cultural Cognition Project, a group of scholars who study how cultural values shape public perceptions and policy

A new strain of mosquitoes in which females cannot fly may help curb the transmission of dengue fever, according to UC Irvine and British scientists. Great idea or frankensketter?

"Here is an innovation borne of the need to make solar modules that are more able to capture more sunlight in regions like New York (or Germany) that have relatively low level insolation. Normally that means that it takes more panels to make the same power, which means it simply costs more to make the same electricity in upstate New York than in the Southern California desert. Prism Solar Technologies in Highland, NY has innovated a breakthrough holographic thin-film (Holographic Planar Concentrator™) that makes possible a very parsimonious use of crystalline PV cells to counteract that problem for Northern region"

Soon the word "hella" may not be associated with California surfers as much as with scientists in lab coats. A physics student is petitioning to add "hella" to the International System of Units (SI) as the official designation of 10 to the 27th power, or a trillion trillions.
