No single number has been more celebrated than the Fibonacci sequence. Alternately kowtowed to as the Golden Ratio, the Divine Proportion, and That One Really Awesome Spiral, this famous number sequence has dazzled mathematicians and nerds for centuries—and practically spawned a cottage arts and design industry in its honor.

It is a sequence in which each number is the sum of the two numbers before it:  0, 1, 1, 2, 3, 5, 8, 13, etc. It produces numbers which roughly equal 1.6 when divided by the number just before them in the sequence. For example: In the pair 3 and 5,  5 divided by 3 is 1.6. In the pair 5 and 8, 8 divided by 5 is 1.6, and so on. Thus we have a sequence of number pairs with ratios that are roughly the same as the ratios of the pair just before them.

The Fibonacci sequence, which is the closest rational number approximation we have of the golden ratio of 1.6, leads us to famous images of the divine proportion in action, most notably this rectangle built on an increasing aspect ratio of the sequence. As you can see, each section has the same ratio as the smaller section.

If this symmetry makes you feel all zen, you’re in luck: The golden ratio pops up again and again throughout nature and often by design in art, architecture, and even film, as people have cottoned onto the mostly disprovable notion that it’s the ideal proportion.

10) These Fibonacci tuning forks

Apparently a regular set of tuning forks contains the first four numbers in the Fibonacci sequence, but this set is an all-Fibonacci upgrade: “The upgrade contains the following new tuning forks, and because they are not notes they are listed as Fibonacci number ratios. They are 5/8, 8/13, 13/21 and 21/34.”
