If you've ever caught yourself fantasizing about infinite series of irrational numbers while out in the woods, this video is for you. Or if you just like cool graphics. Cristobal Vila's Nature by Numbers: As you may've noticed, an important motif in the video is the Fibonacci Sequence. The series starts with 0 and 1. After those first two, you can calculate each subsequent number in the series by adding the previous two: 0 + 1 = 1, 1 + 1 = 2, 1 + 2 = 3, 2 + 3 = 5 . . . Thus 0, 1, 1, 2, 3, 5 . . . Among other things, the series is good for making a Fibonacci Spiral (from squares with side lengths defined by each number in the sequence) which sort of matches a Golden Spiral, which sort of matches a Nautilus shell. The complete explanation of the numbers behind the nature is available on the Vila's website, here.
