Fun Fibonacci facts:
- the first published use of the term “golden section” (which later became more commonly known as the “golden ratio”) to describe the number phi[1] was by Martin Ohm, the brother of Georg Ohm who the unit is named after.
- Binet’s closed form series solution for the Fibonacci numbers[2] is really cool because it involves three irrational numbers yet every term of the resulting series is of course an integer.
[1] (1+sqrt(5))/2
[2] F(n)=(phi^n - psi^n)/ sqrt(5) (n=0,1,2,…) where phi=(1+sqrt(5))/2 and psi=(1-sqrt(5))/2
