This is the first time that scientists have succeeded in masking an event

A team at Cornell University, with support from Darpa, the Pentagon’s out-there research arm, managed to hide an event moncler jackets for 40 picoseconds (those are trillionths of seconds, if you’re counting). They’ve published their groundbreaking research in this week’s edition of the journal Nature.

This is the first time that scientists have succeeded in masking an event, though research teams have in recent years made remarkable strides in cloaking objects. Researchers at the University of Texas, Dallas, last year harnessed the mirage effect to make objects vanish. And in 2010, physicists at the University of St. Andrews made leaps towards using metamaterials to trick human eyes into not seeing what was right in front of them.

Masking an object entails bending light around that object. If the light doesn’t actually hit an object, then that object won’t be visible to the human eye.

Where events are concerned, concealment relies on changing the speed of light. Light that’s emitted from actions, as they happen, moncler jackets is what allows us to see those actions happen. Usually, that light comes in a constant flow. What Cornell researchers did, in simple terms, is tweak that ongoing flow of light — just for a mere iota of time — so that an event could transpire without being observable.

The entire experiment occurred inside a fiber optics cable. Researchers passed a beam of green light down the cable, and had it move through a lens that split the light into two frequencies, one moving slowly and the other faster. As that was happening, they shot a red laser through the beams. Since the laser “shooting” occurred during a teeny, tiny time gap, it was imperceptible.

Sure, the team’s got a ways to go before they’re able to mask 30 seconds of action, let alone several minutes. But the research certainly opens up new possibilities. For one, masking super-quick events, like those that occur with data transmission, could help conceal covert computer operations.

In the words of Nature editors, the research marks “a significant step towards full spatio-temporal cloaking.” But it could be moncler jackets cheap decades before military personnel will basically be able to zap history, as it happens: According to Cornell scientists, it’d take a machine 18,600 miles long to produce a time mask that lasts a single second.

Hello from Sun Life Stadium, where Clemson fans are slowly starting to trickle in and blend in with the orange seats. There are Tiger tracks from Ft. Lauderdale to Miami, as Clemson is making its first appearance here in 30 years. Ticket sales for this game have been poor, and the Miami Herald reported that they were selling for as low as $11 on Tuesday afternoon on stubhub.com. According to the Herald, neither Clemson nor West Virginia had sold out their allotment of 17,500 tickets. Translated: This could look like a Miami home game.

The weather here is a little cool and is expected to be about 60 degrees at kickoff, and a Big Ten crew will be making the calls. This game has been overshadowed by the other BCS bowls, but hopefully it will deliver in entertainment with two of the country's more productive cheap moncler offenses. With a 2-5 record in bowl games and an 0-1 start to the BCS bowls, the pressure is on Clemson to represent the ACC -- same story, different team.
