In mathematics, the Fibonacci numbers are the numbers in the following sequence: 0,1,1,2,3,5,8,13,21,34,55,89,144,…
If you trace the squares of a piece of graph paper using the Fibonacci sequence you will create a pattern like this one:
The side of each square equal the sum of the previous two squares. The squares become progressively larger following the Fibonacci sequence.
Copy this pattern on to a piece of graph paper and continue to add squares, following this sequence until you run out of room.
Next draw a spiral starting at the first number one and getting progressively larger as it arcs through each square. It should grow smoothly and touch two diagonally opposite corners on each square in the sequence.
Congratulations! You have created your very own Fibonacci spiral.
The rectangle that is formed by your Fibonacci sequence is known to mathematicians and artists as the golden rectangle. click here to learn more about the golden rectangle.
WHAT IS THE CONNECTION BETWEEN THE SPIRALS IN PLANTS AND THE FIBONACCI SPIRAL IN MATHEMATICS?

Warning: There is a great deal of misinformation about the Fibonacci spiral on the Internet. The Fibonacci spiral is not found in nautilus shells, ram's horns, spiral galaxies or spider webs.
Occasionally, you might find a few numbers from the Fibonacci sequence in a ram's horn or a sea shell but no known animal consistently forms spirals in this manner the way plants do. Click here to visit an excellent website that debunks the most common myths about the Fibonacci spiral.
Spirals are beautiful and amazing in their own right but they do not hold the key to all the secrets of the universe as some would have you believe. Enjoy them for their beauty and mystery and let them inspire you to create magnificent art.
