The "architect" in bees-worker bees. The nest they built is a strict hexagonal cylinder-a flat hexagonal opening at one end and a closed hexagonal cone at the other end, which consists of three identical diamonds. Interestingly, no matter what kind of beehive, all obtuse angles of the rhombus forming the chassis are equal to 109 degrees 28 minutes, and all acute angles are equal to 70 degrees 32 minutes. This data is exactly the same as that confirmed by mathematicians that "the largest diamond-shaped container needs the least materials". Ants are also very good at calculating. British scientist Henston once did an interesting experiment: he cut a dead grasshopper into three pieces according to the volume of "4,2, 1". When the ants found these three pieces of food for 40 minutes, the ratio of the numbers gathered at the food end was exactly "4,2, 1". The spider's gossip web is a complex and beautiful octagonal geometric pattern. Even with a ruler or compass, it is difficult for people to draw things like cobwebs. When a cat sleeps in winter, it always hugs its body into a ball. There is math in it. Because the sphere minimizes the surface area of the body, it also gives off the least heat. The mole is almost blind, but the tunnel it digs underground always turns 90 degrees. Red-crowned cranes always migrate in groups in the shape of "human", and the included angle of this "human" shape is always 1 10 degrees. According to scientists, half the angle of the herringbone is exactly the angle of the diamond crystal. Is this a coincidence or a tacit understanding of nature? It is still a mystery.
