The initial injection (iteration 1) is represented by the first triangle – which has an arbitrary area of 1. The next round adds 3 extra triangles, increasing the total area of the snowflake. This (principle) process continues until the changes in area of the triangle – after each iteration – changes the total area of the snowflake no more. In the diagram above the total area reaches 1.6, at around the 12th iteration.
- From this it can be inferred or deduced – due to its principle similarity – that the multiplier effect is a universal fractal phenomena, and that the Keynesian observation stands as further evidence that fractals are our reality – that reality is best understood by understanding fractal geometry.
- It is of interest to me (the author), and of my mathematician colleague’s, that the Koch snowflake fractal multiplier is 1.6. This 1.6 is very close to (but not the same as!) the Fibonacci or Golden ratio of 1.618.
A classroom demonstration:
(In class) the multiplier can be demonstrated by having the students pass on (for example) 50% of a piece of sheet paper(see the below photo) careful to save the other 50%. The 1st and largest half represents the initial injection, and the 11th and smallest half (the last the paper can be divided). The iterations multiply a factor of 2 times of the 1st half.
