Few experiences on the road are more perplexing than phantom traffic jams. Most of us have experienced one: The vehicle ahead of you suddenly brakes, forcing you to brake, and making the driver behind you brake. But, soon afterward, you and the cars around you accelerate back to the original speed—and it becomes clear that there were no obstacles on the road, and apparently no cause for the slowdown. Because traffic quickly resumes its original speed, phantom traffic jams usually don’t cause major delays. But neither are they just minor nuisances. They are hot spots for accidents because they force unexpected braking. And the unsteady driving they cause is not good for your car, causing wear and tear and poor gas mileage.
Mathematical model shows how hundreds of starlings coordinate their movements in flight.
A flock of starlings flies as one, a spectacular display in which each bird flits about as if in a well-choreographed dance. Everyone seems to know exactly when and where to turn. Now, for the first time, researchers have measured how that knowledge moves through the flock—a behavior that mirrors certain quantum phenomena of liquid helium.
Scientists have researched the effectiveness of deep learning techniques for discovering exotic particles and found some significant improvements over previous methods. They believe deep learning could help analyze data from the Large Hadron Collider.
London's tech economy is booming as apps and games made there entertain the world and experts predict the first global trillion-dollar company will rise in the UK, most likely in big data. What is the secret to this rapid success?
If you have ever been near a train when it starts to move, you see (and hear) something interesting. The engine car at the front starts to move and in doing so, you get this wave of compressing couplings between all the cars. There is some interesting physics here.
Supercomputing: The Behind-the-Scenes Star of the Summer Blockbuster Wired As I watch more and more movies, I notice just how convincing CGI is becoming, and this is largely due to the amount of computational power used to render the films.
VentureBeat Google whips up a Chrome app to let data scientists work together VentureBeat “There, the computation needs are usually minimal (and parallel compute resources are easily mixed in when needed) and the data are rarely sensitive.
Gary Bamford's insight:
Must check this one out - could be the answer to undecipherable spreadsheets.
A chance discovery about the 'wonder material' graphene -- already exciting scientists because of its potential uses in electronics, energy storage and energy generation -- takes it a step closer to being used in medicine and human health.
Martin Plenio – Towards quantum technologies Youris.com The idea is that information—represented by physical quantities such as the spin or the polarisation of an individual photon—can be transmitted with the help of so-called quantum entanglement.
Extrasolar planet HD189733b rises from behind its star. The new work presented here shows this planet has 20 times more methane than previously thought. Image Credit: ESA The search for life is largely limited to the search for water.
