Crop circle - 15Sep09

Crop circles are patterns created by the flattening of crops such as wheat, barley, rye, or corn.

There is scant evidence that crop circles are anything but man-made hoaxes. Nevertheless various alternative hypotheses have been offered to explain the formation of crop circles such as the paranormal. It has also been suggested that ball lightning and vortices in the wind might rarely produce isolated indentations in crops.

The term crop circle was first used by paranormal researcher Colin Andrew[citation needed] to describe simple circles he was researching. While patterns involving complex geometries have been observed, the term circle has stuck as a generic term for crop patterns.

Bower and Chorley claimed to have started the crop circle phenomenon in 1978[6] and were awarded an Ig Nobel Prize in 1992 for their crop circle hoaxing.
麥田圈(Crop circle)是在麥田或其他農田上,透過某種力量把農作物壓平而產生出幾何圖案。此現象在1970年代後期才開始引起公眾注意。目前,有眾多麥田圈事件被他人或者自己揭發為有人故意製造出來以取樂或者招攬遊客。唯麥田圈中的作物「平順倒塌」方式以及植物莖節點的燒焦痕跡並不是人力壓平所能做到,也有麻省理工學院學生試圖用自製設備反向複製此一現象但依然未能達成,至今仍然沒有解釋該現象是何種設備或做法能夠達到。此點也是外星支持論者的主要物證基礎
