Fibonacci's Spiral

'Fibonacci's Spiral'
Exhibited as part of Intersections installed at the
Market Place Art Centre, Armagh, April 2012

 


1, 1, 2, 3, 5, 8, 13, 21, ... is the beginning of Leonardo Fibonacci's number sequence. This recurrent sequence was originally published in 1202 in Fibonacci's book Liber Abaci. The sequence is also related to the golden ratio and pi. The golden ratio and pi are approximated by the ratio of consecutive Fibonacci numbers, with the approximation increasing in accuracy further along the sequence. Fibonacci's numbers can be seen throughout nature, in for instance the breeding habits of rabbits, snail shells and spiral galaxies. The artwork uses a triangular construction of Fibonacci's sequence, which gives two spiral arms instead of the usual one.

The artwork utilises both colour and texture.
