Well, it's not a funny picture...
If you want a detailed "splanation" to "edumacate" you, here it is, but you may want to read it all later when the coffee kicks in...
Under the Wave off Kanagawa (Kanagawa oki nami ura), also known as The Great Wave, from the series “Thirty-Six Views of Mount Fuji (Fugaku sanjūrokkei)”
Katsushika Hokusai’s much celebrated series, Thirty-Six Views of Mount Fuji (Fugaku sanjûrokkei), was begun in 1830, when the artist was 70 years old. This tour-de-force series established the popularity of landscape prints, which continues to this day. Perhaps most striking about the series is Hokusai’s copious use of the newly affordable Berlin blue pigment, featured in many of the compositions in the color for the sky and water. Mount Fuji is the protagonist in each scene, viewed from afar or up close, during various weather conditions and seasons, and from all directions.
THE FIBONACCI SEQUENCE, SPIRALS
The Fibonacci sequence exhibits a certain numerical pattern which originated as the answer to an exercise in the first ever high school algebra text. This pattern turned out to have an interest and importance far beyond what its creator imagined. It can be used to model or describe an amazing variety of phenomena, in mathematics and science, art and nature. The mathematical ideas the Fibonacci sequence leads to, such as the golden ratio, spirals and self- similar curves, have long been appreciated for their charm and beauty, but no one can really explain why they are echoed so clearly in the world of art and nature.
Spirals arise from a property of growth called
self-similarity or scaling - the tendency to grow in size but to maintain the same shape. Not all organisms grow in this self-similar manner. We have seen that adult people, for example, are not just scaled up babies: babies have larger heads, shorter legs, and a longer torso relative to their size. But if we look for example at the shell of the chambered nautilus we see a differnet growth pattern. As the nautilus outgrows each chamber, it builds new chambers for itself, always the same shape - if you imagine a very long-lived nautilus, its shell would spiral around and around, growing ever larger but always looking exactly the same at every scale.
Here is where Fibonacci comes in - we can build a squarish sort of nautilus by starting with a square of size 1 and successively building on new rooms whose sizes correspond to the Fibonacci sequence:
