In Tallinn, the ticket inspectors are still there though. And you can get fined if you are a local resident and should ride free, but forgot to "buy" your free ticket by swiping the RFID card in the bus. Even after several court rulings undoing such fines.

However, the idea of free public transport, is not that bad, if feasible. In Tallinn, it used to be heavily subsidized anyway, with only ~20% of the money coming from ticket sales (IIRC). They are also planning to extend this to railways within the city, which are operated by private companies - would definitely make some commutes quicker.

+ - Physicists Create Quantum Link Between Photons That Don't Exist at the Same Time->

Submitted by sciencehabit
sciencehabit (1205606) 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.""

An anonymous reader writes "At Google I/O 2013, Google gave a presentation called 'Voiding Your Warranty: Hacking Glass,' which will ultimately benefit Google as much as third-party developers.

Where end-users fear to tread, developers are called. Drawn to the challenge of rooting Android devices that would scare end-users, developers could not resist an invitation to the Google I/O session Voiding Your Warranty: Hacking Glass."

Submitted by astroengine
astroengine (1577233) writes "The mother of all cosmic collisions has been spotted between two galaxies containing a total of 400 billion stars, igniting the birth of 2,000 new stars per year! This incredible event was first spotted by the recently-retired Hershel infrared space observatory, a mission managed by the European Space Agency. This violent discovery isn't just awesome to look at, it could also help explain how massive, red elliptical galaxies evolved in the early universe."

+ - Will Robots Take Over the Data Center?->

Submitted by 1sockchuck
1sockchuck (826398) writes "Robotics are beginning to be integrated into data center management, creating the potential for a fully automated, robot-driven data center. What might a robot-controlled "lights-out" data center look like? The racks will be taller, as robotics systems can reach higher to manage servers. Robotic equipment would be mounted on rails that allow them to find and move hardware. Early examples of this are seen in tape libraries, but the concepts could be applied to other data center equipment. Amazon and Google are said to be among those looking at ways to create a fully automated data center. AOL says it has already built an unmanned data center. Data Center Knowledge looks at the challenges and opportunities in robot-controlled data centers, including how staff roles would evolve."

Submitted by asavin
asavin (2516080) writes "The latest results from CERN experiments observed a particle consistent with long-sought Higgs Boson.

"We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage," said ATLAS experiment spokesperson Fabiola Gianotti, "but a little more time is needed to prepare these results for publication.""

Solving that differential equation analytically (as opposed to numerically) will yield an analytic solution to this problem. Also, accounting for the initial conditions is part of solving an equation. A differential equation itself does not give an answer (neither exact or approximate) - you have to solve it using some method (which can be exact, approximate or numerical).

The right hand side of the closed form solution might also include integration (eg if there are some integrals which cannot be represented using elementary functions), infinite series etc and it would still count as an analytic solution (although I suppose it depends on the exact definition of "analytic solution"), even though evaluating it for some particular point in time (in this particular case) can not be done exactly (you would have to numerically evaluate the integrals etc).

Granted, as has been pointed out, GP has not provided us with an analytic solution to that equation.

Submitted by MistrX
MistrX (1566617) writes ""While there are plenty of ways to make carbon-based products from CO2, these methods usually require a lot of energy because the CO2 molecules are so stable. If the energy comes from the burning of fossil fuels, then the net result will be more CO2 entering the atmosphere. Now a material scientist at Michigan Technological University has discovered a chemical reaction that not only soaks up CO2, but also produces useful chemicals along with significant amounts of energy."

Submitted by

Fluffeh writes "The EU has accused Google of abusing its dominant position in advertising to benefit its own advertising services at the expense of competitors. In a twist however, rather than initiating formal proceedings, the EU has given Google a chance to settle the whole matter without much fuss. They outlined four changes that Google can make that will put it firmly back in the good graces of the EU. Google has been given "a matter of weeks" to propose remedies to the four issues — which all tie in with how search results are displayed, their format and their portability to other platforms. This matter has come before the EU based on complaints by a few small companies and Microsoft."

+ - Scientists Unravel the Mystery of the 'Dark Day' 1

Submitted by
Hugh Pickens writes
Hugh Pickens writes writes "BBC reports that 232 years ago a strange event occurred that remains shrouded in mystery to this day. On May 19, 1780 the sky turned yellow in New England and Canada, animals ran for cover and darkness descended, causing people to light candles and start to pray. By lunchtime night had fallen. With little scientific knowledge amongst the populace, people were afraid and some lawmakers in Connecticut believed it was the day of judgment. "There are some verses in Matthew that might have led them to believe that this is the second coming of Christ," says historian Mike Dash. "At the time, natural events — even birds fighting in the sky — were a sign of God's intentions. The Dark Day would have seemed like a warning to Man." A solar eclipse can be ruled out as there is a record of when these occur — and they only last for a matter of minutes, there is no record of volcanic activity in 1780 making a huge ash cloud an unlikely explanation, and a meteorite is equally unlikely. Now scientists may have found the answer in the trees. Academics at the University of Missouri's Department of Forestry analyzed tree trunks inland from New England, where westerly prevailing winds would originate and found signs of fire-scarred rings in tree trunks dating back to that period in the area that is today occupied by Algonquin Provincial Park. Eyewitness accounts in New England support the forest fire hypothesis as soot was spotted in rivers, and one letter noted that the air had the "smell of a malt-house or a coal-kiln". Whatever the cause in 1780, geography must have exacerbated the fear, says Dash with European settlers living on the edge of a vast unknown continent. "When it goes dark for them, there's no guarantee it is ever going to get light again," says Dash. "In those days it would be quite natural to think it was the Second Coming.""
