The recent disclosure of Nano man lead me to this guy Gerald Hawkins.

He studied a number of crop circles and noticed that they pointed out geometric theories that we're in any text book.

It's no wonder that farmers with fields in the plains surrounding Stonehenge, in southern England, face late-summer mornings with dread. On any given day at the height of the growing season, as many as a dozen farmers are likely to find a field marred by a circle of flattened grain.

Plagued by some enigmatic nocturnal pest, the farmers must contend not only with damage to their crops but also with the intrusions of excitable journalists, gullible tourists, befuddled scientists, and indefatigable investigators of the phenomenon.

Indeed, the study of these mysterious crop circles has itself grown into a thriving cottage industry of sightings, measurements, speculations, and publications. Serious enthusiasts call themselves cereologists, after Ceres, the Roman goddess of agriculture.

Most crop deformations appear as simple, nearly perfect circles of grain flattened in a spiral pattern. But a significant number consist of circles in groups, circles inside rings, or circles with spurs and other appendages. Within these geometric forms, the grain itself may be laid down in various patterns.

Explanations of the phenomenon range from the bizarre and the unnatural to the merely fantastic. To some people, the circles—which began appearing nearly 3 decades ago—represent the handiwork of extraterrestrial visitors. Others attribute the formations to crafty tradesmen bent on mischief after an evening at the pub, pranksters commemorating a recent movie, or even hordes of graduate students driven by a mad professor. To a few, the circles suggest the action of numerate whirlwinds, microwave-generated ball lightning, or some other peculiar atmospheric phenomenon.

These scenarios apparently suffered a severe blow in 1991, when two elderly landscape painters, David Chorley and Douglas Bower, admitted to creating many of the giant, circular wheat-field patterns that had cropped up during the previous decade in southern England. The chuckling hoaxers proudly displayed the wooden planks, ball of string, and primitive sighting device they claimed they had used to construct the circles......

Rare video of Gerald Hawkins lecturing on his crop circle theories



He was more famous for his amazing book on Stonehenge called 'Stonehenge Decode'
In which he claimed the 56 Aubrey holes which circle Stonehenge could be used to predict lunar eclipses a result which is strongly debated

But the ancients of Europe were fascinated by lunar and solar cycles; amazing Golden Hats attest to this.

It's been suggested they may also have been used to calculate eclipses
