Welcome to WikiProject Golden ratio. Some Wikipedians have formed this collaboration resource and group dedicated to improving Wikipedia's coverage of Golden ratio and the organization of information and articles on this topic. This page and its subpages contain their suggestions and various resources; it is hoped that this project will help to focus the efforts of other Wikipedians interested in the topic. If you would like to help, please join the project, inquire on the talk page and see the to-do list below.

• Categorize the articles about golden ratio and promote the global development of the topic.

• Golden ratio in the universe
• Golden ratio in human production
• The evolution of the use and knowledge of the golden ratio through history

• Categorize the works that have been recognized by featuring golden ratio in their design.
• Explain how these works feature golden ratio in their design in their respective articles.

Please feel free to add yourself here, and to indicate any areas of particular interest.

Dudeney), the number of petals in flowers, the sunflower spirals, the pine cones, species of Radiolaria (shaped like polyhedra) and viruses (such as the herpes virus, have the shape of a regular icosahedron).

    The sequence was first studied by Leonardo of Pisa, known as Fibonacci, this book. He considers the growth of an idealized (biologically unrealistic) rabbit population, assuming that: a)in the first month there is just one newly-born pair, b) new-born pairs become fertile from after their second month, c)each month every fertile pair begets a new pair, and c)the rabbits never die.
