Shape of the Universe The shape of the universe is the local and global geometry of the universe, in terms of both curvature and topology (though, strictly speaking, it goes beyond both). When physicsist describe the universe as being flat or nearly flat, they're talking geometry: how space and time are warped according to general relativity. When they talk about whether it open or closed, they're referring to its topology.[1] Although the shape of the universe is still a matter of debate in physical cosmology, based on the recent Wilkinson Microwave Anisotropy Probe (WMAP) measurements "We now know that the universe is flat with only a 0.4% margin of error", according to NASA scientists. [2] Theorists have been trying to construct a formal mathematical model of the shape of the universe. In formal terms, this is a 3-manifold model corresponding to the spatial section (in comoving coordinates) of the 4-dimensional space-time of the universe. Two aspects of shape[edit] Local geometry (spatial curvature)[edit]

Culturomics Further reading[edit] References[edit] External links[edit] Culturomics.org, website by The Cultural Observatory at Harvard directed by Erez Lieberman Aiden and Jean-Baptiste Michel Tumblr Luddite fallacy Technological unemployment is unemployment primarily caused by technological change. Given that technological change generally increases productivity, it is a tenet held in economics since the 19th century that technological change, although it disrupts the careers of individuals and the health of particular firms, produces opportunities for the creation of new, unrelated jobs. The notion of technological unemployment leading to structural unemployment (and being macroeconomically injurious) is often called the Luddite fallacy, named after the early historical example of the Luddites.[1][1][2][3] Views[edit] [If] the Luddite fallacy were true we would all be out of work because productivity has been increasing for two centuries John Maynard Keynes used the term as early as 1930, stating: "We are being afflicted with a new disease of which some readers may not yet have heard the name, but of which they will hear a great deal in the years to come-namely, technological unemployment.
mylife Ten Miles Square - Big Bird and the Cultural Contradictions of Capitalism December 30, 2011 11:44 AMBig Bird and the Cultural Contradictions of Capitalism By Harold Pollack According to the Wall Street Journal: GOP presidential candidate Mitt Romney says he wants to reduce the deficit by bringing commercials to PBS. This is not the most important political or policy debate these days. Romney’s suggestion provides an obvious dog whistle to cultural conservatives, who seem to harbor an amazing hatred for public broadcasting. The irony here is that PBS and the national endowments are profoundly conservative enterprises. PBS provides a rare safe haven from the crude and cruddy world of commercial television, which is such a destructive force in so many ways in American life. There’s also the simple fact that most commercial television is relentlessly and depressingly bad. Sure, the federal government could save a little money by cutting back on subsidies to Sesame Street. Know-nothing attacks on PBS provide yet another sad sign of a mediocre time. Back to Home page
Welcome — Cincinnati State The Magazine - The Myth of American Productivity January/ February 2012The Myth of American Productivity Politicians say we have the most productive workers in the world. They don't know what they're talking about. By Michael Mandel In 1939, when John Steinbeck completed The Grapes of Wrath—a heart-wrenching tale of a family of sharecroppers forced out of their home during the Depression— roughly one-quarter of the U.S. population still lived on farms. But rather than viewing the decline of farming jobs as a tragedy, economists almost invariably count agriculture as a shining American success—the triumph of productivity. As the story of the American economy is usually told, the shrinkage of agricultural employment was a tough but essential part of the march toward higher incomes and a better standard of living. In a 2006 speech, University of Chicago professor Austan Goolsbee made the same point, explaining why the long-term decline in manufacturing jobs didn’t worry him. There are two big problems with this theory, however.
primenumbersturnmeon comments on Why is WTF posting child porn? WTF, WTF? New drug may keep you sober no matter how much you've had to drink Imagine a pill that could instantly sober you up no matter how much you've had to drink, or a hangover cure that worked minutes after swallowing it. Hardened drinkers rejoice: researchers are about to begin human trials on an "alcohol antidote" that may soon offer a cure to alcoholism, reports New Scientist. The drug is a chemical called dihydromyricetin, or DHM, and is derived from a Chinese variety of the oriental raisin tree, which has been used for at least 500 years in China as an effective hangover cure. "DHM will reduce the degree of drunkenness for the amount of alcohol drunk and will definitely reduce the hangover symptoms," said Jing Liang, lead researcher in the study. Liang first tested how well DHM alleviated drunken rats' clumsiness and loss of coordination by measuring how long it took them to right themselves after being laid on their backs. The rats were next tested within a maze to see how well DHM neutralized hangover symptoms.
US Cycle Tourist Russ Roca Victim Of Road Rage Last updated 05:00 12/01/2012 KENT BLECHYNDEN/Fairfax NZ SHOCKED: United States cycle tourists Russ Roca and Laura Crawford. "The whole thing was surreal,'' said Mr Roca. Have you been a victim of road rage? A road rage attack on an American cyclist in Wellington has been condemned as an embarrassment to New Zealand. Russ Roca, 33, was tackled to the ground and punched in the face by a motorist in Newtown on Tuesday. Roca and his partner, Laura Crawford, 32, of Oregon, have been riding the New Zealand Cycle Trail for more than a month without any problems from motorists. They were riding their collapsible bikes on a two-lane section of Riddiford St about 4.30pm when a man driving a silver sedan passed them "really really close, almost aggressively", he said. "So the natural reaction was to shout 'What's going on?' The motorist, described as a 30-something male of average build with black hair, pulled over and came at the cyclists, Roca said. "Laura swerved around him but I wasn't so lucky.
I don't know if anyone else noticed this.. Winter advisory issued as season's first serious snow storm takes aim at Chicago The season's first serious storm is expected to dump as much as 8 inches of snow on the Chicago area Thursday and Friday, and the National Weather Service says high winds and plunging temperatures could make traveling hazardous. Snow will start falling sometime Thursday morning, but the brunt of the storm could hit during the evening rush, according to the National Weather Service. Even the morning rush on Friday could be dicey because of plunging temperatures and blowing snow. The weather service has issued a winter weather advisory in effect from 9 a.m. Thursday until 9 a.m. "Strong winds will cause considerable blowing and drifting snow, especially in outlying and open areas. "Accumulating snow will likely make travel difficult for the afternoon commute Thursday, with travel conditions possibly becoming treacherous and even dangerous in open areas Thursday night into early Friday morning." "It'll be light to moderate snow that will last for 24 hours," Allsopp said.
