·柯布西耶着迷，促使他真正的进入了一项“关于比例尺度研究的内容与精神”的领域。

After abstraction, everything in nature is invariably generalized by mathematical geometry. Even if an ordinary plant, its trunk, branches, leaves and veins grow and combine in a more varied and ingenious way, is it possible that there is some mathematical connection that intervenes in natural things? This idea fascinated Le Corbusier and led him to enter the realm of the content and spirit of the study of proportional scales.

Suppose a person is 1.75m tall and raises his arms to nearly 2.2m high, which is equivalent to two stacked 1.1m squares, try to embed the third square in it and test it in the way of right-angle trajectory. This phenomenon, similar to the Fibonacci sequence, gives a human scale to the rational and boring numbers through the association of mathematical geometry.
