November 23, 2019 ## 1, 1, 2, 3: It's Fibonacci Day!

Today's date, November 23, can be represented as 11/23, or 1, 1, 2, 3—the beginning of the Fibonacci sequence of numbers. Likewise, as the leaves on the Queen Victoria agave in today's image spiral out from the center, they also express the Fibonacci sequence. This unique sequence of numbers was introduced to Europe in 1202 by the Italian mathematician Leonardo of Pisa (posthumously named Fibonacci) in his revolutionary work, the 'Liber Abaci.' The book begins by describing the Hindu-Arabic numeral system or 'Modus Indorum’—0 1 2 3 4 5 6 7 8 9—and shows how its application could simplify trade and make calculations faster and easier (most of Europe at this time used Roman numerals).

In the third section of his book, Fibonacci goes on to describe various mathematical problems, including a thought experiment about increasing rabbit populations that results in the Fibonacci sequence. The sequence is determined by adding the previous two numbers together to establish the next number: 1, 1, 2, 3, 5, 8, 13, 21, 34, etc. Since then, mathematicians, scientists, and artists have been studying and applying the Fibonacci sequence and the Fibonacci numbers that make it up. While Fibonacci gets the credit for describing the number sequence, he wasn't the first to discover it. Research published in 1985 posits that ancient Indian mathematicians had been aware of and wrote about the sequence more than a thousand years before Fibonacci's work.

https://en.wikipedia.org/wiki/Fibonacci_number翻譯此頁

Fibonacci numbers are named after Italian mathematician Leonardo of Pisa, later known as Fibonacci. They appear to have first arisen as early as 200 BC in work by Pingala on enumerating possible patterns of poetry formed from syllables of two lengths.

Every 3rd number is a multiple of 2 (2, 8, 34, 144, 610, ...) Look at the number x 4 = 3. Every 4th number is a multiple of 3 (3, 21, 144, ...) Look at the number x 5 = 5. Every 5th number is a multiple of 5 (5, 55, 610, ...) And so on (every nth number is a multiple of x n).

The hint was a small, jumbled portion of numbers from the Fibonacci sequence. The sanctity arises from how innocuous, yet influential, these numbers are. A new number in the pattern can be generated by simply adding the previous two numbers. Starting from 0 and 1 (Fibonacci originally listed them starting from 1 and 1, but modern mathematicians prefer 0 and 1), we get:0,1,1,2,3,5,8,13,21,34,55,89,144…610,987,1597…We can find …
