For years, researchers have debated the causes of Crop Circles. Several theories on who or what is making the strange patterns that appear mysteriously overnight in farmers’ fields have been put forward in past decades.
According to researchers, the first crop circles was reported near the small town of Tully, Australia. Back in 1966, a farmer allegedly saw a flying saucer rise up from a swampy area and disappeared. Curious, he went to explore and spotted a circular area of flattened grass, which according to him had been made by the alien spacecraft. Though this story is more a UFO report than a crop circle one, the flattened circular designed really caught the attention of researchers.
The number of weird patterns created by flattening of crops has significantly increased from the 1970s to current times. Moreover, crop circle designs have become more complex than ever. Some designs have up to 2,000 different shapes. According to mathematical analysis the use of construction lines to govern the pattern are indispensable, although exactly how crop circles are created remains mysterious.
In July 1996, one of the most complex crop circles was spotted in England. The design was that of a fractal pattern called a Julia Set. Unlike the usual simple circle design, this one was unmistakably different and demonstrated intelligence which rose the question whether that intelligence was terrestrial or extra-terrestrial?

In the August 2011 issue of Physics World Richard Taylor, director of the Materials Science Institute at the University of Oregon explained that there is a possibility that crop-circle artists might be using GPS, lasers or microwaves to design these unique crop-circle art.
“It may seem odd for a physicist such as Taylor to be studying crop circles, but then he is merely trying to act like any good scientist – examining the evidence for the design and construction of crop circles without getting carried away by the side-show of UFOs, hoaxes and aliens,” said Matin Durrani, editor of Physics World.
