A Model of Plant Leaves Based on the Fibonacci Sequence
One of the most beautiful and widely appreciated concepts in mathematics is the Fibonacci sequence. It appears in the forms and growth patterns of plants, seashells, and many other natural objects. More recently, it has even found applications in Topological Quantum Computation through the concept of the Fibonacci anyon.
Recently, I happened to discover an item called the “Fibonacci Tree” being sold online as a desk ornament or educational toy. Although the product itself does not seem to come with a mathematical explanation, it appears to be an object whose beauty can be appreciated simply by displaying it on a desk.
With that in mind, I would like to give a brief introduction to it below.
古くからある、誰にも親しまれる美しい数学の一つにフィボナッチ数列がある。植物や貝類などの形態に現れる他、最近では、トポロジカル量子計算(Topological Quantum Computation)における「フィボナッチ・アニオン(Fibonacci Anyon)」にも利用されるようである。
最近、偶然だが、ネット上で「フィボナッチツリー」なるものが、文具かおもちゃとして発売されているのを知った。数学的な説明などはないが、机上において美しさを味わうことができるように思う。そこで、以下の通り、簡単にご紹介します。
