Reconstruction of the Stone circles at Avebury, Wiltshire

Reconstruction (after J. Britton) of the Stone circles at Avebury, Wiltshire - The Great stone circle, it is said, was approached by two avenues of 200 stones each, which took a sinuous course south-east and south-west and represented a snake transmitted through a circle. Stukeley put its foundation at 1859 BC, the year of the death of Sarah, Abraham's wife (!!). The present village of Avebury has grown up amidst the stones of his ancient temple'.

Fibonacci spiral and Phi, artwork

Fibonacci spiral and Phi, computer artwork. The constant Phi, written to 866 decimal places, is calculated as (1 + square root of five, divided by 2). Also seen is a spiral within squares whose sides decrease in length by a factor of 0.168. This number (phi) is derived from the golden ratio Phi (1.618). The spiral is formed by drawing a quarter circle in each box. It resembles that seen in nature, such as the shape of a snail's shell or the segmentation of a pine cone. The Fibonacci spiral was named after the Italian mathematician Leonardo Fibonacci (1170- 1230), and is also known as an equiangular or logarithmic spiral
