La proporción dorada de la vida cotidiana


Because of its aesthetic qualities, embodied in its unique ability to relate the parts to whole, golden ratios are used in the design of many modern household items, from coffeepots, cassette tapes, playing cars, pens, radios, books, bicycles, and computers screens, to tables, chairs, windows and doorways. It even comes into literature, in the page layout of medieval manuscripts and as the small winged Golden Snitch in the Harry Potter stories.

Other important rectangles also find their way into our daily lives. The continuous geometric proportion most perfectly expressed in the golden series is mimicked in the International Standard Paper Size (2), which employs the continuous geometric proportion of 2:√2::√2:1. Where as removing a square from a golden rectable produces another golden rectagle, folding a √2 rectangle in half produces two smaller √2 rectangles. Thus folding a sheet of A3 (2:√2) in half, fives you two sheets of A4 (each √2:1).

Scott Olsen. The Golden Section: Nature’s Greatest Secret. 2006. La proporción dorada es la base de un patrón que se repite tanto en la naturaleza (plantas, animales) como en cosas hechas por el hombre (pinturas, edificios, tamaños de papel). O también: la espiral perfecta. Fibonacci lo destajó en números, y Leonardo Da Vinci lo ilustraba bajo la menor provocación.
