Revision as of 20:41, 15 March 2008

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.

Goals

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

Scope

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

Guidelines

Open tasks

  • 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.

Participants

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

Articles

Featured content

Candidates

New articles

Please feel free to list your new Golden Ratio-related articles here (newer articles at the top, please). Any new articles that have an interesting or unusual fact in them, are at least over 1,000 characters, don't have any dispute templates on them, and cite their sources, should be suggested for the Did you know? box on the Wikipedia Main Page.

Review and assessment

Peer review
Assessment

Templates

We need a stub template, and template to put in the talk pages of the related articles.

Categories

For articles dedicated to explain the properties or aspects of golden ratio.
(NOTE: Not for articles about stuff that happens to have golden proportions)
For articles dedicated to explain the properties or aspects of the Fibonacci numbers.
(NOTE: Not for articles about stuff that happens to be related to the Fibonacci numbers)
Proposals
  • Other proposed names for this category (propose here): Designs with golden proportions, works with golden proportions.
  • Category:Organisms in published studies of the golden ratios (virtually any organism has it, but this is only for organisms that have been specifically studied in diverse publications dedicated to the golden ratio)
    Some examples of organisms in published studies of the golden ratios: The nautilus, the human body proportion, the reproduction of rabbits (Fibonacci started by observing the rabbits), the reproduction of cows (Henry E. 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).
  • Category:Golden ratio in the universe (stars, orbits, planets, etc)
    • Other proposed names for this category (propose here): Golden proportions in astronomy

Resources

List of sources

Here is a list of recommended sources to be used in the related articles.

Writings of the historic researchers

  • PINGALA, Chandah-shāstra, the Art of Prosody. 450 or 200 BC.
  • FIBONACCI
    • Liber Abaci. 1202.
      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.
    • Practica Geometriae (1220), a compendium on geometry and trigonometry.
    • Flos (1225), solutions to problems posed by Johannes of Palermo
    • Liber quadratorum, ("The Book of Squares") on Diophantine equations, devoted to Emperor Frederick II. See in particular Fibonacci's identity.
    • Di minor guisa (on commercial arithmetic; lost)
    • Commentary on Book X of Euclid's Elements (lost)
  • PACIOLI, Luca. De divina proportione. Venice, 1509.
    The architectural treaty that guided the reinassanse artists.
  • KEPLER, Johannes A New Year Gift: On Hexagonal Snow. Oxford University Press, 92. ISBN 0198581203. Strena seu de Nive Sexangula (1611)
  • GHYKA, Matyla

    • Le nombre d'or. 1931.
    • The Geometry of Art and Life. 1946
    • A Handbook of Practical Geometry. 1952.
  • LE CORBUSIER
    • The Modulor. 1948.
      The book in which Le Corbusier proposes a system that uses units derivated from the human body and the golden ratio.
    • The Modulor 2. 1955

Scientific journals, courses and publications

  • KNOTT, Ron. Fibonacci's Rabbits. University of Surrey School of Electronics and Physical Sciences.
  • KNUTH, Donald. The Art of Computer Programming.
