You have probably seen it in movies: When the moon is full, a man turns into a hairy, frightening creature and runs around the city, tearing people to pieces. You may laugh at stories of wolf men, but have you ever wondered where the association of a full moon with crazy goings-on came from?

你可能曾在电影中看到：月圆时分，一个男人变成毛茸茸的骇人怪物在城市里四处横行，把人撕成碎片。你也许对狼人的故事感到好笑，但你可曾好奇过满月与疯狂举动之间的联系从何而来？
