Fractal and chaos IA ideas: self-similarity, dimension and sensitive dependence

Fractals and chaos look like advanced mathematics, but the core ideas sit on top of the syllabus: geometric series give the perimeter and area of a snowflake curve, logarithms give a fractal dimension, and a simple quadratic iterated over and over can behave unpredictably.

The danger is a beautiful but descriptive IA: pictures of the Mandelbrot set and a history of Benoit Mandelbrot earn few marks. Choose one object and ask a precise question about it that you can calculate, measure or prove.

The Koch curve after three stages, made of 64 segments each one twenty-seventh of the original length, with its length and dimension
The Koch curve after three stages: length grows by 4/3 at every stage, so it is unbounded, while the curve stays in a finite region.

Frequently asked questions

Is a fractal IA suitable for SL?

Yes. Snowflake curves, Sierpiński shapes and box-counting dimension need only geometric series and logarithms. Keep the question precise and the calculations your own.

How do I avoid a fractal IA that is just pictures?

Ask a question with a numerical answer (what is the dimension, where does the period double, what is the limit of the area) and spend your pages calculating, testing and reflecting on that answer.
