400 million years wisdom

四億年の知恵

 

シダ類はおよそ四億年前から地上に生息し、その形状を大幅に変える事なく大地、大気、太陽との関係性の中、光合成を繰り返してきた。シダは今でも容易に見ることが出来るが、近ずいて観察すると、その構成は実にユニークである。

羊歯植物はフラクタルと呼ばれる形状を備えており、一つの形、例えば三角形を何度も反芻する事で自形を成す。この原始的な形の仕組みは養分を葉の隅々まで届けることが、実に容易に出来ており、光を透射させる為の機能性などは、正に永年の「知恵」としか言いようがない。

 

400 million years wisdom

 

Ferns inhabit the earth from about 400million years ago.The shape has not changed drastically in the long years, and it has repeated photosynthesis in the relation to the Earth, the air , and the sun.

Ferns are still easy to see, but if you observe them closely , their composition is really unique. The fern plant has a shape called fractal, which forms one form, for example,

by repeatedly looking over a triangle.

The mechanism of this primitive form makes it really easy to deliver nourishment to easy corner of the leaf, and the function of transmitting light can be said only with wisdom accumulated over many years.
