The Golden Rectangle and
golden ratio and Galapagos Islands.
Successive Golden Rectangles dividing a Golden Rectangle into squares
A golden rectangle
is a rectangle whose side lengths are in the golden ratio, one-to-phi, that is, approximately 1:1.618.
A distinctive feature of this shape is that when a square section is removed, the remainder is another golden rectangle, that is, with the same proportions as the first. Square removal can be repeated infinitely, which leads to an approximation of the golden
or Fibonacci spiral.
(0,1,1,2,3,5,8,13,21,34...) are a sequence of numbers named after Leonardo of Pisa, known as Fibonacci.
The first number of the sequence is 0, the second number is 1, and each subsequent number is equal to
the sum of the previous two numbers of the sequence itself.
The Galápagos Islands are an archipelago of volcanic islands distributed around the equator, 972 km west of continental Ecuador in the Pacific Ocean. The islands are famed for their vast number of endemic species and the studies by Charles Darwin during the voyage of the Beagle that contributed to the inception of Darwin's theory of evolution by natural selection.
