Researchers illuminate the hidden properties of light By Euan McKirdy, CNN Updated 0715 GMT (1515 HKT) May 18, 2016 Story highlights "We thought it was impossible for a photon to send you halfway round," scientist Paul Eastham says Light, it seems, doesn't necessarily conform to the rules we thought it did (CNN)When it comes to understanding light, it turns out we're more in the dark than we thought. Researchers in Ireland have reported that they discovered a "new form" of light, and, in a press release, say that their discovery "will impact our understanding of the fundamental nature of light." The discovery was published in the scientific journal "Science Advances." The recent discovery by physicists at Ireland's Trinity College Dublin could alter our established thinking of how a key aspect of light -- its angular momentum -- is understood. Angular momentum is a measurement of how something rotates around its own axis , which light is known to do. Essentially, as photons -- tiny particles of light -- travel through space, they twist and turn around their axes. Previously it was thought that light's angular momentum was a constant, but the team at Trinity discovered that under certain conditions, it only spins around its axis half as much as it should. Light, it seems, doesn't necessarily conform to the rules we thought it did. This could mean big things, the researchers say. "It's a bit like a tiny, light merry-go-round at a playground. It goes round and round, which is more or less they way people understood light to work. We thought it was impossible for a photon to send you halfway round, but it turns out, it's not," lead researcher Paul Eastham told CNN. "What I think is so exciting about this result is that even this fundamental property of light, that physicists have always thought was fixed, can be changed," he said. "But this science is in a very early stage -- the next stage is to work out the consequences, how this could be used in everyday life," Eastham said. Eastham suggested that the discovery could have implications for telecommunications and privacy. The nature of these newly found photons are by nature harder to crack, meaning they could deliver data without such a high threat of a third party snooping. It could be used in fiber-optic cables to improve speed and security.

Director of CRANN Stefano Sanvito called the work "fundamental scientific research that challenges our understanding of light. "The topic of light has always been one of interest to physicists, while also being documented as one of the areas of physics that is best understood. This discovery is a breakthrough for the world of physics and science alike."

"这有点像超小的旋转木马。它一直转一直转，让人们或多或少了解光是如何运作的。 我们认为光子只转一半是不可能的，但结果，它就是发生了。"主要研究员Paul Eastham 在CNN说道。 "这个光性质的结果真的是令人太兴奋了，物理学家们以为的既定事实是可以被改变的。" 他说。 "但这项研究还是在非常早期的阶段，下一步是实践这份结果，要怎麽将其应用在我们的 日常生活。"Eastham说道。 Eastham认为这个发现可以对通讯和隐私科技有所帮助。这些新发现的光子性质本质上是 难以被破解的，代表说资料传输时可能不会再受到第三方监听的威胁了。也可能用在改善 光纤缆线的速度及安全性。 ========================================================== 大概就酱 其实也没说什麽内容 有物理性的能解释下吗? 4.完整新闻连结 (或短网址): ※ 当新闻连结过长时，需提供短网址方便网友点击 http://goo.gl/rSsaUO 5.备注: ※ 一个人一天只能张贴一则新闻，被删或自删也算额度内，超贴者水桶，请注意 光子在某种状况下，角动量只会绕轴转一半 <--重点部分的翻译 跨拢谋 有人能解释一下吗? 话说发现隐藏属性 GM会不会抓啊? -- 不要因为有配着伟人照片，就随便相信网路上流传的名言佳句。──胡适 不要相信胡适。──爱因斯坦 --
