FYI - The Fibonacci Sequence

The Fibonacci sequence is a simple number pattern where each number is the sum of the two before it. It usually starts like this:

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

So:

• 0 + 1 = 1
• 1 + 1 = 2
• 1 + 2 = 3
• 2 + 3 = 5
  …and so on.

In simple terms, it’s a “build-on-the-last-two” pattern.

What makes it interesting is how often it shows up in nature. You can see Fibonacci-like patterns in things that grow or spread efficiently:

Sunflower heads are a classic example. The seeds spiral in two directions, and the counts of those spirals are often Fibonacci numbers like 34 and 55.

Pinecones and pineapples also show this pattern in their spiral scales. If you count them in different directions, you’ll often get Fibonacci numbers.

You’ll also see it in the way leaves grow around a stem, called phyllotaxis. This arrangement helps each leaf get the most sunlight without blocking others.

Even shells, like nautilus shells, follow a similar idea. They don’t match the sequence exactly, but they grow in a spiral that expands in a way closely related to Fibonacci growth patterns.

The key idea isn’t that nature is “following a rule,” but that this pattern naturally appears when things grow efficiently and evenly in limited space.
