Location: Helix, floor 3
Artist Lambert van Erp designed this construction as an image and material representation of the Golden Ratio. Ever since Fibonacci, Phi (often written as Fi in Dutch) has stood for beauty and harmony in ratios and dimensions in art, architecture and nature. In this sculpture the Golden Ratio has been applied consistently: in the height of the wooden parts from top to bottom, also in the length of the steel pipes from bottom to top and in the diamater of the vertical pipes and the more horizontal connecting pipes. Therefore Van Erp gave his work the title "Fi".
In 1175 Leonardo Pisano (Leonard of Pisa) was born as son to Bonacci; in mathematical writings his name was changed to Fibonacci. He was educated in North Africa and in 1202 he wrote 'Liber Abaci' ('The book on the abacus') about algebra and Roman numerals, including the figure zero. This work introduced the numerical system to Europe. Fibonacci is often considered the first western mathematician to publish original work since Greek antiquity. Fibonacci is best known for his Fibonacci series. The ratio of two consecutive Fibonacci numbers approaches the Golden Ratio. In the limit this ratio even equals it.
The Fibonacci series consists of numbers, each following term being equal to the sum of both immediately preceding terms: 1-2-3-5-8-13-21-34 etc. More important however is that the ratio of two consecutive terms approaches the value 0,618, which is the Golden Ratio.
TU/e rector Rutger van Santen purchased Lambert van Erp's work in 2006.
