Battle to Save Nikola Tesla Laboratory :: peaceblaster. Published: May 4, 2009 In 1901, Nikola Tesla began work on a global system of giant towers meant to relay through the air not only news, stock reports and even pictures but also, unbeknown to investors such as J. Pierpont Morgan, free electricity for one and all. It was the inventor’s biggest project, and his most audacious. The first tower rose on rural Long Island and, by 1903, stood more than 18 stories tall. One midsummer night, it emitted a dull rumble and proceeded to hurl bolts of electricity into the sky. The blinding flashes, The New York Sun reported, “seemed to shoot off into the darkness on some mysterious errand.” But the system failed for want of money, and at least partly for scientific viability. Today, a fight is looming over the ghostly remains of that site, called Wardenclyffe — what Tesla authorities call the only surviving workplace of the eccentric genius who dreamed countless big dreams while pioneering wireless communication and alternating current.
Dr. Sonic Black Hole Traps Sound Waves :: peaceblaster. June 17, 2009 — A black hole created by Israeli scientists won’t destroy Earth, but it could make our planet just a little bit less noisy. Using Bose-Einstein condensates, the scientists created a black hole for sound. The new research could help scientists learn more about true black holes and help confirm the existence of as-yet to be discovered Hawking radiation. “It’s like a black hole because waves get sucked in and can’t escape,” said Jeff Steinhauer, a scientist at the Israel Institute of Technology and the corresponding author of the article recently posted on the ArXiv.org pre-print Web page.
“But in this case we use sound waves instead of light.” To create the sonic black hole, the scientists first had to create the Bose-Einstein condensate, a cloud of atoms cooled to almost absolute zero that acts like a light wave. The Israeli scientists actually created two clouds of rubidium 87 atoms cooled to 50 nano Kelvins and separated by a small gap. Continue Reading.

A General view of the CERN (European Organization for Nuclear research) on February 12, 2009 in Geneva, Switzerland. (Zunino Celotto/Getty Images) The European Organization for Nuclear Research (CERN) has managed to trap anti-hydrogen atoms for at least 16 minutes and believes this relatively stable form of antimatter will allow further studies of these rare and mysterious particles. Scientists running the ALPHA (Antihydrogen Laser Physics Apparatus) experiment at CERN in Geneva, Switzerland are building an antimatter trap, and their findings to date were published online in Nature Physics on June 5. “We’ve trapped antihydrogen atoms for as long as 1,000 seconds, which is forever,” said Joel Fajans from the University of California (UC), Berkeley in a press release.
The team trapped 112 antiatoms for up to 1,000 seconds, or 16 minutes and 40 seconds, and have caught 309 anti-atoms since their first successful capture in 2009. Technicolor (physics) Technicolor theories are models of physics beyond the standard model that address electroweak gauge symmetry breaking, the mechanism through which W and Z bosons acquire masses. Early technicolor theories were modelled on quantum chromodynamics (QCD), the "color" theory of the strong nuclear force, which inspired their name. In order to produce quark and lepton masses, technicolor has to be "extended" by additional gauge interactions. Particularly when modelled on QCD, extended technicolor is challenged by experimental constraints on flavor-changing neutral current and precision electroweak measurements.
It is not known what is the extended technicolor dynamics. Much technicolor research focuses on exploring strongly interacting gauge theories other than QCD, in order to evade some of these challenges. The mechanism for the breaking of electroweak gauge symmetry in the Standard Model of elementary particle interactions remains unknown. Forms. . Here, at the scale μ. Is small there. . And.

The candidate particle may not belong to the standard model of particle physics, physicists' best theory for how particles and forces interact. The observation was made by Fermilab's CDF experiment, which smashes together protons and antiprotons 2 million times every second. Physicists predicted that the number of these events – producing a W boson and a pair of jets – would fall off as the mass of the jet pair increased.
