New Paper Claims Neutrino Is Likely a Faster-Than-Light Particle 8

Posted by timothy

HughPickens.com writes Phys.org reports that in a new paper accepted by the journal Astroparticle Physics, Robert Ehrlich, a recently retired physicist from George Mason University, claims that the neutrino is very likely a tachyon or faster-than-light particle. Ehrlich's new claim of faster-than-light neutrinos is based on a much more sensitive method than measuring their speed, namely by finding their mass. The result relies on tachyons having an imaginary mass, or a negative mass squared. Imaginary mass particles have the weird property that they speed up as they lose energy – the value of their imaginary mass being defined by the rate at which this occurs. According to Ehrlich, the magnitude of the neutrino's imaginary mass is 0.33 electronvolts, or 2/3 of a millionth that of an electron. He deduces this value by showing that six different observations from cosmic rays, cosmology, and particle physics all yield this same value within their margin of error. One check on Ehrlich's claim could come from the experiment known as KATRIN, which should start taking data in 2015. In this experiment the mass of the neutrino could be revealed by looking at the shape of the spectrum in the beta decay of tritium, the heaviest isotope of hydrogen.

But be careful. There have been many such claims, the last being in 2011 when the "OPERA" experiment measured the speed of neutrinos and claimed they travelled a tiny amount faster than light. When their speed was measured again the original result was found to be in error – the result of a loose cable no less. "Before you try designing a "tachyon telephone" to send messages back in time to your earlier self it might be prudent to see if Ehrlich's claim is corroborated by others."

Boston Elementary, Middle Schools To Get a Longer Day 47

Posted by timothy
from the am-I-being-detained dept.
Many public elementary- and middle-school students in Boston may soon have a longer time to spend in school each day. A change, announced Friday by Boston mayor Martin J. Walsh, though yet to get final approval from the city's school committee and teachers' unions' full membership, would add 40 minutes to the schedule at schools not already under an extended schedule. Currently, most elementary school students have a 6-hour day, and middle school students' is 10 minutes longer, which means that high schools will now have by default the shortest day (six and a half hours) in the Boston public school system. From the Boston Globe's coverage: Teachers in the 60 schools would get an annual stipend of $4,464 for the expanded schedule, the mayor’s office said. The plan would be rolled out over three years, beginning with about 20 schools in the 2015-2016 school year, the statement said. Officials said it wasn’t clear which schools would be in the first group. Once fully rolled out, the plan, which would add up to about an extra month of learning per year for 23,000 students, would cost about $12.5 million per year. How long is the school day in your neck of the woods, and do you think it should be any longer?

First Airbus A350 XWB Delivered, Will Start Service in January 24

jones_supa writes The wait is finally over for aviation aficionados wanting to book a flight aboard the Airbus A350 XWB. Qatar Airways, the global launch customer of the plane, accepted delivery of their first A350 of 80 in order, during a ceremony at Airbus' headquarters in Toulouse, France, on Monday morning. This particular A350-900 will enter regular commercial service in January, operating daily flights between its Hamad International Airport hub in Doha, Qatar and Frankfurt, Germany. There are three different iterations of A350 XWB being built: the A350-800, the A350-900 and the A350-1000, which seat 270, 314 and 350 passengers, respectively, in three-class seating. The "XWB" in the name means "extra wide body." The A350 is the first Airbus with both fuselage and wing structures made primarily of carbon-fiber-reinforced polymer. Curious what it was like to be on the Tuesday delivery flight? Jeremy Dwyer-Lindgren was onboard that flight and chronicled the landmark trip in photographs.

New submitter Siddharth Srinivas writes Bharti Airtel Ltd, India's largest telecommunications carrier by subscribers, will soon start charging users extra money for using services such as Skype, as Indian operators look to boost their data network and revenues. The Telecom Regulation Authority of India (TRAI) is no stranger to Net Neutrality, having sent a note to the ISPs in 2006 suggesting a position for Net Neutrality. TRAI had also recently rejected a proposal by Airtel and other operators the right to charge for free services such as Whatsapp. Consumers await TRAI's response to Airtel's new pricing. With no laws enforcing net neutrality in India. India's Net Neutrality discussions have just begun, with proponents rapidly trying to increase awareness.

from the aren't-you-glad-those-are-machines dept.
As reported by Reuters, Korean manufacturing giant LG's Seoul headquarters have been raided over allegations that LG employees sabotaged dishwashers made by rival Samsung. The Samsung machines were "on display at two stores in September ahead of the IFA electronics show in Berlin." From the article: On Friday, investigators searched the Seoul offices of LG Elec's home appliance head, Jo Seong-jin, and others and secured documents and computer hard disks related to the IFA fair, Yonhap News Agency said. They also combed through LG Electronics' home appliance factory in the southeastern city of Changwon, the report said. ... Samsung sued LG Electronics employees after the incident in Germany, and LG said the company has counter-sued Samsung employees on Dec. 12. Media reports have earlier said prosecutors banned LG's Seong-jin from leaving the country ahead of the Consumer Electronics Show (CES) to be held January 6-9.

An anonymous reader writes isoHunt, the group now best known for launching The Old Pirate Bay, has shared an update a week after debuting The Open Bay. The Pirate Bay, the most popular file sharing website on the planet, still isn't back following police raids on its data center in Sweden, but its "cause" is very much alive. So far, 372 "copies" of The Pirate Bay have been created thanks to the project. The torrent database dump, which combines content from isoHunt, KickassTorrents (via its public API), and The Old Pirate Bay, has seen 1,256 downloads to date.

Lizard Squad Targets Tor 71

Posted by Soulskill
from the reasons-"torget"-should-be-a-word dept.
mrspoonsi tips news that Lizard Squad, the hacker group who knocked Xbox Live and the PlayStation Network offline on Christmas morning, has now turned its attention to Tor. After tweeting that they were targeting a Tor-related zero-day flaw, the group is now in control of 3,000 exit nodes — almost half of them. "If one group is controlling the majority of the nodes, it could be able to eavesdrop on a substantial number of vulnerable users. Which means Lizard Squad could gain the power to track Tor users if it infiltrates enough of the network."

No, they can't legally sell them in the USA anymore without some serious engineering changes. They got a waiver on some of the safety regulations that has expired. They also had a limited contract with Lotus for the bodies.

So to do a new run of roadsters, they would have to do a lot of engineering and essentially make a new car. Right now, they don't have the capacity in engineering or production to make more models; they're struggling to get the Model X out, and they've got their eyes on the III.

I wouldn't be surprised if they make a new Roadster eventually, but I would put it at five years out at the earliest.

Besides, given the performance of the P85D, I'm not sure how much more there would be besides a different body shape.

Paul Graham: Let the Other 95% of Great Programmers In 403

Posted by Soulskill
from the giveme-your-tired,-your-poor,-your-huddled-hackers dept.
An anonymous reader writes: Y Combinator's Paul Graham has posted an essay arguing in favor of relaxed immigration rules. His argument is straight-forward: with only 5% of the world's population, the U.S. can only expect about 5% of great programmers to be born here. He says, "What the anti-immigration people don't understand is that there is a huge variation in ability between competent programmers and exceptional ones, and while you can train people to be competent, you can't train them to be exceptional. Exceptional programmers have an aptitude for and interest in programming that is not merely the product of training."

Graham says even a dramatic boost to the training of programmers within the U.S. can't hope to match the resources available elsewhere. "We have the potential to ensure that the U.S. remains a technology superpower just by letting in a few thousand great programmers a year. What a colossal mistake it would be to let that opportunity slip. It could easily be the defining mistake this generation of American politicians later become famous for."

The absent ones are always at fault.
