The Golden Rectangle and
golden ratio and Grand Canyon.
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.
