eso0847 - Astronomers Dissect a Supermassive Black Hole with Natural Magnifying Glasses eso0847 — Science Release 12 December 2008 Combining a double natural "magnifying glass" with the power of ESO's Very Large Telescope, astronomers have scrutinised the inner parts of the disc around a supermassive black hole 10 billion light-years away. Articles on "Electricity" Why three prongs?Why do wall outlets have three holes? "Grounding" and safety. Right Angle CircuitryDo Lenz' Law and the Right Hand rule still work... after you've been turned INSIDE OUT by that greasy black Fog? "Static Electric" misconceptionsA list of things which gave me a warped view of Electrostatics. Once I recognized their existence, I was able to fight free of them.
Cosmos is a fantastic show about ideological conversion more than it’s about science Like Carl Sagan before him, Neil deGrasse Tyson is constructing a cult of personality. Also like Sagan, that personality is not his own. In both its versions, Cosmos has had to serve a number of masters — they’ve both had to educate, to entertain, and to bring in advertising. By far their most defining goal, however, the one that most differentiates them from both the Planet Earths and Bill Nyes of the world, is ideological. Cosmos was, and very thankfully still is, an unabashed attempt to exalt the scientist and to advance the scientific worldview in its entirety, with as few tactful omissions as possible.
Homeschooled children have higher graduation rates, more social prowess (NaturalNews) Homeschooling, once steeped in negativity and subject to eyebrow-raising naysayers, is fast-sweeping the nation as an alternative educational method that comes with higher graduation rates than traditional schooling.(1) In fact, there are approximately 2.2 million students in the United States who receive home education, and experts note that its popularity has continued, rather than waned, through the years. These students have been found to score up to 30 percentile points above public-school students on standardized academic achievement tests.(2) With homeschooling, children are taught under the direction of family members who maintain that learning at home allows youngsters to obtain customized instruction that public schools do not regularly provide, while simultaneously strengthening family relationships in a safe environment.(2) Higher graduation rates, test scores among homeschooled children Homeschooled children more prepared socially for real-world scenarios (1)
NASA discovers portals (but don’t book your ticket yet) Madeleine L’Engle called them tesseracts. The Syfy channel calls them wormholes. Gamers call them portals. Whatever you call them, they are fictional doorways to faraway places: another planet in the solar system … another star in the galaxy … another restaurant where the service doesn’t suck quite so bad. But today they’re perhaps a little less fictional than yesterday. At least according to a Science@NASA post: Hidden Portals in Earth’s Magnetic Field, which says they are real, sort of. Teardrop from Heaven: Aurora Australis Posted on 18/07/2012 by Daniel We may have been the last folk to see the Aurora in Antarctica, but when it came, it was unforgettable. Aurora Australis seen from Concordia Station 18 July 2012 Credit: ESA/IPEV/ENEAA/A. Kumar & E. Bondoux Incredible displays of coloured light, termed Aurora, are produced by collisions, when electrically charged particles travelling from the sun impact with charged particles in the atmosphere, as they enter the atmosphere.
