Fibonacci number series and Cauliflower in HD

Leonardo Fibonacci (c. 1170 c. 1250), an Italian mathematician, is credited with bringing the Fibonacci sequence to the attention of medieval Europe. Some scholars believe the famous number series to be known to the ancient mathematicians of India, possibly as early as the 4th century BC. The Fibonacci number series is the sum of previous two numbers with the first numbers being 0 and 1. Thus the sequence begins 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, etc. Curiously, this series often appears in nature, for example, sea shells, plants and even the orbit of some planets in the solar system. The higher up in the sequence, the closer two consecutive "Fibonacci numbers" of the sequence divided by each other will approach the golden ratio (approximately 1 : 1.618 or 0.618 : 1). Our video of the Romanesco cauliflower is a particularly interesting example of the Fibonacci series found in nature.
