A strange 300-foot pattern of circles and lines recently appeared in a farmer's field in the English countryside near Wiltshire, a place long associated with mysteries such as crop circles and Stonehenge. According to crop circle researcher Lucy Pringle the pattern contains a hidden code for a complex mathematical equation called Euler's Identity, considered by many to be among the world's most beautiful and elegant theorems.
This is not the first time that images and concepts from advanced mathematics have appeared in farmers' fields. Crop circle designs containing fractal patterns (such as the Mandelbrot set) have been created for many years.

"Dr. John Talbot, a mathematician at University College London, noted that the hoaxers actually made a mistake in creating Euler's Identity. Talbot, interviewed by The Independent Online noted an error in part of the equation and even found some very human humor in the supposedly alien pattern: "One of the discrepancies is that one part of the formula translates as 'hi' rather than 'i', which could be somebody’s idea of a joke." So either the aliens who traveled across the universe to make a pattern in an English farmer's field misunderstood Euler's Identity, or perhaps merry pranksters tossed a joke into their design for fun."
