Crop Circles I

Crop circle is the greatest mystery which is still unfolded along with Bermuda Triangle. This mystery started  from 1500th century  and still continues. Crop circles are patterns that appear in fields. The pattern is created when certain areas of the crops are tamped down, but others are left intact. The edge is so clean that it looks like it was created with a machine.

Sometimes, these patterns are simple circles. In other instances, they are elaborate designs consisting of several interconnecting geometric shapes. Farmers have reported finding strange circles in their fields for centuries. The earliest mention of a crop circle dates back to the 1500s. Up till now,these crop circles appeared in 26 countries but most of the crop circles are appeared in southern England.

The sun sets on a field in southern England. When it rises again the following morning, that field has been transformed into an enormous work of art. A large section of the crop has been tamped into a pattern of circles, rings and other intricate geometric shapes. But who created it? Well That’s the mystery.

Are crop circles are creature of aliens? Are they a natural phenomenon, created by electrically charged currents of air? Or are they created by talented and very determined circlemakers? Believers and scientists each have their own theories, but the truth remains elusive.

In a 17th-century English woodcut shows a devilish creature making a crop circle. People who lived in that area called the creature the "mowing devil." Mentions of crop circles were sporadic until the 20th century, when circles began appearing in the 1960s and '70s in England and the United States. But the phenomenon didn't gain attention until 1980, when a farmer in Wiltshire County, England, discovered three circles, each about 60 feet (18 meters) across, in his oat crops. UFO researchers and media descended on the farm, and the world first began to learn about crop circles.

By the 1990s, crop circles had become something of a tourist attraction. In 1990 alone, more than 500 circles emerged in Europe. Within the next few years, there were thousands. Visitors came from around the world to see them. Some farmers even charged admission to their mysterious attractions in their own farm.

Crop circles can range in size from a few inches to a few hundred feet across. Most early crop circles were simple circular designs. But after 1990, the circles became more elaborate. More complex & specially bigger in size. Crops circles can be made to look like just about anything  smiling faces, flowers or even words. Crop circles are sometimes unique designs, but they can also be based on ancient motifs. 

Some of the more sophisticated patterns are based on mathematical equations. Astronomer and former Boston University professor Gerald S. Hawkins studied several crop circles and found that the positions of the circles, triangles and other shapes were placed based on specific numerical relationships. The specific placement of the shapes indicates that, whoever the circlemakers are, they have an intricate knowledge of Euclidean geometry (the geometry of a flat surface introduced by the mathematician Euclid of Alexandria).
