Today’s date, 5/8/13, is mathematically very interesting… did you notice?

These three numbers are a part of the Fibonacci series! In the Fibonacci series, each number is the sum of the two previous ones: 0, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 and so on… The ratio between a Fibonacci number and the previous one gets closer and closer to φ, the “golden number”. The properties of φ makes it appear in many contexts in nature…

To see how pine cones, terminal buds, flowers and other natural shapes are related to the Fibonacci series, have a look at this set of videos, they are great!
