Is space like a chessboard? - 0 views

  •  
    "While studying graphene's electronic properties, professor Chris Regan and graduate student Matthew Mecklenburg found that a particle can acquire spin by living in a space with two types of positions -- dark tiles and light tiles. The particle seems to spin if the tiles are so close together that their separation cannot be detected. "An electron's spin might arise because space at very small distances is not smooth, but rather segmented, like a chessboard," Regan said."

YouTube - Bill Nye - Greatest Discoveries - 1: Astronomy - 0 views

  •  
    Bill Nye and the Discovery Channel give you the greatest discoveries in science. In this episode, Nye covers Einstein's theory of general relativity, demonstrates how Hubble determined that the universe is expanding, and discusses the 20th-century advancements that help us understand gamma ray bursts, black holes, pulsars, and quasars. Highlights include Edmond Halley, whose discovery of comets orbiting the sun proved that gravity works in space, and Alexander and Caroline Herschel, whose map of the sky brought new understanding of the universe.

Space Skydiver Suit Revealed : Discovery News - 0 views

    "Austrian skydiver Felix Baumgartner wants to attempt a record-breaking free fall from 120,000 feet above the Earth. It's not the kind of jump a person can do with a conventional sky-diving suit and helmet. After all, Baumgartner will break the speed of sound during his fall. He will need life-support."

YouTube - Asteroid Discovery From 1980 - 2010 - 1 views

  •  
    "View of the solar system showing the locations of all the asteroids starting in 1980, as asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones. The final colour of an asteroids indicates how closely it comes to the inner solar system. Earth Crossers are Red Earth Approachers (Perihelion less than 1.3AU) are Yellow All Others are Green Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video. As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner. At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths. Currently we have observed over half a million minor planets, and the discovery rates snow no sign that we're running out of undiscovered objects. Orbital elements were taken from the 'astorb.dat' data created by Ted Bowell and associates at http://www.naic.edu/~nolan/astorb.html"

YouTube - The Known Universe by AMNH - 0 views

  •  
    The Known Universe takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum, is part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

Artificial cooling of Earth could reverse global warming - Technology & Science - CBC News - 0 views

  •  
    "A report released late Thursday in London and discussed Friday at the U.N. climate conference in South Africa said that - in theory - reflecting a small amount of sunlight back into space before it strike's the Earth's surface would have an immediate and dramatic effect. Within a few years, global temperatures would return to levels of 250 years ago, before the industrial revolution began dumping carbon dioxide into the air, trapping heat and causing temperatures to rise."

    Throw-away Buildings Thermal Window Failure: How it Happens Virtually all glass condominium towers feature window wall systems (floor-to-ceiling walls of glass) enclosing the entire facade. Window walls yield spectacular views, but owners who buy a condo unit for the view may not realize that they're relying on a couple of panes of glass separated by less than an inch of insulated space to protect them from the elements. That insulated barrier will degrade over time, even as energy costs increase. On some buildings, five per cent of the thermal windows may have failed before they're even delivered to the construction site. Another 10 - 15 per cent will fail by the 20-year mark as they're exposed to the physics of heat expansion. By the 25 year-mark, a growing number will fail every year.

BBC News - Science news highlights of 2009 - 0 views

  •  
    It was the year we learned of a spectacular smash-up in space, and scientists working on the world's biggest physics experiment delighted at collisions of an entirely different sort. There were shockwaves, too, in Copenhagen, as the summit failed to reach a consensus on tackling climate change, instead merely noting a deal struck by major powers including the US and China. The BBC's science reporter Paul Rincon looks back at the twists and turns of a year in science and the environment.
