### Fibonacci Day: Celebrating the Golden beauty of nature | FlipScience

As far as dates go, 11/23 happens to be of particular significance to mathematicians and number nerds, according to Mikael Angelo Francisco, years of writing and editorial experience under his belt.

 November 23 (11/23) is Fibonacci Day, a special day in honor of the European mathematician who discovered the numerical sequence that manifests itself (rather spectacularly) all throughout nature.

It’s widely recognized as Fibonacci Day, because the numbers on the date match the first four numbers in the famed Fibonacci sequence.

In the Philippines, we tend to write dates the same way Americans do, so this can apply to us as well. (Think about it: It actually makes more sense for Filipinos to celebrate this than Thanksgiving Day.)...

A hare-raising tale The Fibonacci sequence is sophisticated in its simplicity. After the first two numbers (0 and 1), each succeeding number is the sum of the two numbers before it.

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144…

This interesting sequence was first observed and described by Leonardo of Pisa, more commonly known as Leonardo Fibonacci. “Fibonacci” is short for “filius Bonacci” (“son of Bonaccio”). Fibonacci accomplished quite a few things, including making the Hindu-Arabic numeral system more popular with European audiences via his book Liber Abaci (“The Book of Calculations”)...

The Fibonacci number in nature
Take any two successive numbers in the sequence, and their ratio will be almost exactly the same as the Golden Ratio (1.6). The Golden Ratio (also called the “divine proportion”) is regarded as a universal standard of beauty. To maximize aesthetic appeal, craftsmen base the length and width/breadth of their creations on the Golden Ratio. Consider the size and composition of many Greek temples (which tend to be 1.618 times as long as they are wide) or the Egyptian pyramids (as the base length of a pyramid is 1.618 times its height).

The Fibonacci sequence also manifests constantly in nature, almost without fail.
