Fibonacci Forgot the Number Squares. First, what are the Fibonacci numbers? The Fibonacci numbers are a sequence of numbers in mathematics named after Leonardo of Pisa. Fibonacci wrote a book in 1202, called Liber Abaci (“Book of Calculation”). He introduced the number pattern to Western European mathematics. Mathematicians in India already knew of it.^{[1]}^{[2]}

Here we start with #1.This is because zero was not considered a number in the remote past. In the more modern series, number one repeats. Each number after that is equal to adding the two numbers right before it together. For example, 1 + 1=2. Then 1 + 2 = 3. Next, 2 + 3 =5. Next, 3 + 5 = 8. This sequence can go on forever. Note: Five breaks the consecutive number series of 1,2,3. It skips number “4”. Therefore, I call five the 1st distinct Fibonacci number. It is also the first central number of the 1st number square of the series. It sits at the center of the 3 x 3 number square.

A Fibonacci spiral created by drawing a line through the squares in the Fibonacci tiling. This one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34; see Golden spiral.

What Fibonacci Forgot is Key to Understanding

We just mentioned the centrality of #5 in number squares. Number 13 is at the center of the 5 x 5 square. All evenly numbered squares have 4 numbers at the center. The 4 x 4 square is the 1st such square. Its 4 numbers of 7,6,10 and 11 total 34. This is yet another Fibonacci number that comes from the heart of number squares. The most remarkable is the 3 x 3 number square. It actually frames the infinite Fibonacci series by using repeated fives. Many blogs on DSOworks.com are about this very topic. Here are just two internal links.

What Fibonacci forgot is the heart of the entire matter. It time to place some teeth into this prehistoric series of numbers. Numbers squares can be a guiding light to an uplifting future.
