[火星] 中微子说意呆利你们的节操又掉了

http://news.sciencemag.org/scienceinsider/2012/02/breaking-news-error-undoes-faster.html?ref=hp


It appears that the faster-than-light neutrino results, announced last September by the OPERA collaboration in Italy, was due to a mistake after all. A bad connection between a GPS unit and a computer may be to blame.

Physicists had detected neutrinos travelling from the CERN laboratory in Geneva to the Gran Sasso laboratory near L'Aquila that appeared to make the trip in about 60 nanoseconds less than light speed. Many other physicists suspected that the result was due to some kind of error, given that it seems at odds with Einstein's special theory of relativity, which says nothing can travel faster than the speed of light. That theory has been vindicated by many experiments over the decades.

According to sources familiar with the experiment, the 60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer. After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed. Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.

意呆利..节操又甩了一地..

PS：前些天看了点资料，说二战时意大利是打酱油加搞笑的…确实挺有趣的…巫妖科普一下？

意大利的勇气在罗马帝国时代耗光了,剩下的就是爱情剧

连续两次世界大战意大利的表现都丢死人了……

去看袁腾飞讲的二战吧，意大利真是太搞笑了，非洲土人都打不过

墨索尼里想将意大利重新塑造为罗马,然而事实证明他不是凯撒,意大利也不是罗马.

浪漫的意大利飞行员觉得封闭式设计飞机回让他们感觉不到风吹到脸上的赶脚，所以直到二战战败意大利童鞋都没发明高速战机。。。

我很不明白，元首这么英明的人怎么会和意大利这种国家联盟。。。

你总是需要一个炮灰帮你挡住远处来增援的敌人的。

这个炮灰貌似不太管用。。。

看到这则消息我就理解了今天看到的笑话了...
话说大家都转去评论二战了
