This t-shirt depicts a Fibonacci spiral made up of the numbers in the Fibonacci series.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144… ah, we could go on and on – maybe forever – starting with 0 and 1, the next number is always the sum of the last two. The Fibonacci sequence is naturally-occurring in the whorls of flower petals and pine cone seeds (count them!) and the distribution of leaves around a stem and branches around a tree. In fact, Nature is full of rough logarithms, from the spirals of seashells to the shapes of hurricanes and our own Milky Way.
