Fibonacci numbers “always make mathematicians happy,” said Tara Holm, a mathematician at Cornell University. Their appearance in McDuff and Schlenk’s work, she added, was “some indication ...

The Fibonacci sequence is a series of numbers where each number is the sum of the two preceding ones. It is closely related to the golden ratio, which appears in various natural and artistic contexts.

The key Fibonacci ratio of 61.8% is found by dividing one number in the series by the number that follows it. For example, 21 divided by 34 equals 0.6176, and 55 divided by 89 equals about 0.61798.
