Architect Gaudi once said: "The straight line belongs to human beings and the curve belongs to God. So in his building, it is rare to find a straight line.

People's eyes are straight, any problem is measured by a ruler, and there is no straight line in nature-everything in nature is bent by gravity-so human views must be wrong; God (nature) sees everything with curved eyes, which conforms to the characteristics of nature and is therefore necessarily correct.
