White House: Use Metric If You Want, We Don't Care 795

Posted by Soulskill
from the not-yielding-an-inch dept.
Earlier this year we discussed a petition on the White House's 'We The People' site asking the administration to adopt the metric system as the standard system of measurement in the U.S. Today, the administration issued a disappointing response. Simply put: they're not going to do anything about it. They frame their response as a matter of preserving a citizen's choice to adopt whatever measurement system he wants. Quoting Patrick D. Gallagher of the National Institute of Standards and Technology: "... contrary to what many people may think, the U.S. uses the metric system now to define all basic units used in commerce and trade. At the same time, if the metric system and U.S. customary system are languages of measurement, then the United States is truly a bilingual nation. ... Ultimately, the use of metric in this country is a choice and we would encourage Americans to continue to make the best choice for themselves and for the purpose at hand and to continue to learn how to move seamlessly between both systems. In our voluntary system, it is the consumers who have the power to make this choice. So if you like, "speak" metric at home by setting your digital scales to kilograms and your thermometers to Celsius. Cook in metric with liters and grams and set your GPS to kilometers. ... So choose to live your life in metric if you want, and thank you for signing on."

Physicists Create Quantum Link Between Photons That Don't Exist At the Same Time 359

Posted by samzenpus
from the time-after-time dept.
sciencehabit writes "Physicists have long known that quantum mechanics allows for a subtle connection between quantum particles called entanglement, in which measuring one particle can instantly set the otherwise uncertain condition, or 'state,' of another particle—even if it's light years away. Now, experimenters in Israel have shown that they can entangle two photons that don't even exist at the same time. Anton Zeilinger, a physicist at the University of Vienna, says that the experiment demonstrates just how slippery the concepts of quantum mechanics are. 'It's really neat because it shows more or less that quantum events are outside our everyday notions of space and time.'"

Some Scientists Question Whether Quantum Computer Really Is Quantum 170

Posted by Unknown Lamer
from the qbits-all-the-way-down dept.
gbrumfiel writes "Last week, Google and NASA announced a partnership to buy a new quantum computer from Canadian firm D-Wave Systems. But NPR news reports that many scientists are still questioning whether new machine really is quantum. Long-time critic and computer scientist Scott Aaronson has a long post detailing the current state of affairs. At issue is whether the 512 quantum bits at the processor's core are 'entangled' together. Measuring that entanglement directly destroys it, so D-Wave has had a hard time convincing skeptics. As with all things quantum mechanical, the devil is in the details. Still it may not matter: D-Wave's machine appears to be far faster at solving certain kinds of problems (PDF), regardless of how it works."

3-D Printable Food Gets Funding From NASA 241

cervesaebraciator writes "According to Quartz, '[Anjan Contractor's] Systems & Materials Research Corporation just got a six month, $125,000 grant from NASA to create a prototype of his universal food synthesizer. But Contractor, a mechanical engineer with a background in 3-D printing, envisions a much more mundane — and ultimately more important — use for the technology. He sees a day when every kitchen has a 3-D printer, and the earth's 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor's vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.' No word yet on whether anyone other than the guy trying to sell the technology thinks it'll make palatable food."

Irish Judge Orders 'The Internet' To Delete Video 243

New submitter edanto writes "A young Irish man wrongly accused of jumping from a taxi without paying the fare has secured a judgement from an Irish court ordering the video removed from the entire Internet. Experts from Google, Youtube, Facebook, and others must tell the court in two weeks if this is technically possible. The thing is, the video is accurate, it is only a comment that wrongly identified Eoin McKeogh as the fare-jumper in the video that is inaccurate. It's not clear if the judge has made any orders about the comment."

cylonlover writes "Invisibility cloaks have been around in various forms since 2006, when the first cloak based on optical metamaterials was demonstrated. The design of cloaking devices has come a long way in the past seven years, as illustrated by a simple, yet highly effective, radar cloak developed by Duke University Professor Yaroslav Urzhumov, that can be made using a hobby-level 3D printer."

UN Says: Why Not Eat More Insects? 624

PolygamousRanchKid writes in with news about a U.N. plan to get more bugs in your belly. "The U.N. has new weapons to fight hunger, boost nutrition and reduce pollution, and they might be crawling or flying near you right now: edible insects. The Food and Agriculture Organization on Monday hailed the likes of grasshoppers, ants and other members of the insect world as an underutilized food for people, livestock and pets. Insects are 'extremely efficient' in converting feed into edible meat, the agency said. Most insects are likely to produce fewer environmentally harmful greenhouse gases, and also feed on human and food waste, compost and animal slurry, with the products being used for agricultural feed, the agency said. 'Insects are everywhere and they reproduce quickly,' the agency said, adding they leave a 'low environmental footprint.' The agency noted that its Edible Insect Program is also examining the potential of arachnids, such as spiders and scorpions."

New Flying Car Design Unveiled 233

Posted by samzenpus
from the better-late-than-never dept.
An anonymous reader writes "Terrafugia has unveiled plans to build a semi-autonomous, hybrid-electric, vertical-takeoff-and-landing vehicle for personal aviation. The new design, called TF-X, is in the works even as the company's first product, Transition, is still awaiting production because of technical and regulatory hurdles. Terrafugia's founder says the goal of TF-X, if it can get past the safety issues in both aviation and automotive industries, is to 'open up personal aviation to all of humanity.' But it will have a lot of competition from companies including AgustaWestland, Pipistrel, and the stealthy Zee.Aero, all of which are working on vertical-takeoff-and-landing vehicles for consumers."

They're not warranties. They don't warrant anything at all. They're just insurance. Once you get that clear, it's a straight choice on the basis of cost vs benefit. A real warranty penalises the manufacturer for shoddy goods or inadequate service by making them make good the deficit. That is not the case here.

Physicists Attempting To Test 'Time Crystals' 231

Posted by Soulskill
from the where's-The-Doctor-when-you-need-him dept.
ceview writes "This story at Wired seems to have lots of people a bit confused: 'In February 2012, the Nobel Prize-winning physicist Frank Wilczek decided to go public with a strange and, he worried, somewhat embarrassing idea. Impossible as it seemed, Wilczek had developed an apparent proof of "time crystals" — physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. ... [A] Berkeley-led team will attempt to build a time crystal by injecting 100 calcium ions into a small chamber surrounded by electrodes. The electric field generated by the electrodes will corral the ions in a "trap" 100 microns wide, or roughly the width of a human hair. The scientists must precisely calibrate the electrodes to smooth out the field. Because like charges repel, the ions will space themselves evenly around the outer edge of the trap, forming a crystalline ring.' The experimental set up is incredibly delicate (Bose Einstein Condensate), so it implies this perpetual motion effect can't really be used to extract energy. What is your take on it? It's unlike to upend anything, as the article suggests, because at a quantum level things behave weirdly at the best of times. The heavy details are available at the arXiv."

Stop Standardizing HTML 302

Posted by Unknown Lamer
from the remember-xhtml-2.0 dept.
pfignaux writes with an interesting view on the place of centralized standardization in modern browsers. From the article: "When HTML first appeared, it offered a coherent if limited vocabulary for sharing content on the newly created World Wide Web. Today, after HTML has handed off most of its actual work to other specifications, it's time to stop worrying about this central core and let developers choose their own markup vocabularies and processing." Instead, the author proposes that CSS, Javascript+DOM, the W3C's accessibility framework, and Web Components are sufficient to implement the rendering of smaller, domain-specific markups.

Trouble always comes at the wrong time.
