The Golden Rectangle and Usain Bolt

Successive Golden Rectangles dividing a Golden Rectangle into squares (Usain Bolt in Beijing 2008).

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.

Fibonacci numbers (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.

Usain Bolt (born 21 August 1986) is a Jamaican sprinter. He is the reigning Olympic champion over 100 meters and holds both world and Olympic 100 meters records with a time of 9.69 seconds. Bolt is also the world junior record holder in the 200 meters (19.93 seconds), and Jamaican national record holder in the 200 meters (19.67 seconds). His name and achievements in sprinting have earned him the media nickname "Lightning Bolt".
