Did the pranksters (or ETs or Gaia or the military, etc.) behind this recent crop circle, known as the Wilton Windmill, encode hidden mathematical messages in the pattern? The Daily Grail's Richard Andrews reveals that the mathematically beautiful Euler's Identity equation is encoded in 8-bit binary within the formation. Not only that, but Andrews posits that a minor error in the encoding could be seen as an (unintentional?) reference to the Planck constant. Of course, that would be very punny as many crop circle artists use a plank to flatten the crops.
