Day 70
Challenge: Work only with numbers today.
A snail's shell is ALL about numbers.
This is incredible, if not amazing!
AND hard to keep inside my head.
BUT worth a try.
IF you are mostly a visual learner, I suggest doing a quick Websearch for the topic:

The Fibonacci Sequence [1,1,2,3,5,8,13,21,34,55,84 . . . ]
The numeric steps that lead to the golden ratio are known as the Fibonacci Sequence. The Fibonacci Sequence can be demonstrated by building a plane formation of squares. Start with one square, then add additional squares next to and equal in size to the widest side of the existing rectangle (or initial square). As more and more squares are added, the squares get larger and larger and the ratio between the short and the wide side of the resulting rectangle gets closer and closer to the Golden Ratio of 1.61803399…, but never exceeds it. The ratio is an irrational number, it is never exhausted. The sizes of the squares that you add represent the Fibonacci Sequence. The number in the Fibonacci Sequence is always the total of the previous two numbers, thus the sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, etc. The eventual ratio of the square size to its immediate predecessor represents the Golden Ratio.
What is one of the most amazing revelations is that you see the Fibonacci numbers everywhere in nature. These numbers are Nature's way of counting. Consider the numbering of the growing and living things in nature: 5 teeth in children (each side), 8 teeth of adults, 5 fingers, 5 toes, petals in flowers, seeds on flower heads, and spirals in sunflowers, [and spirals in snails !!!] more often than not match Fibonacci numbers.
