Why I Like Maths - A Visual Explanation - Enter the Mandelbrot

It’s about patterns, logic, beauty and infinity.  The best way to demonstrate this is with fractals and specifically The Mandelbrot Set discovered as recently as 1980. 

The Mandlebrot set is a pattern that’s self replicating and unique, its simple and its complex  and its beautiful. It seemingly goes on forever.

It’s been called the definition of infinity and the “thumbprint of God”. I’m inclined to think the latter is true as you don’t have to look very far in the physical world to find Mandlebrot designs – carved in stone on Indian temples, under the microscope, in the fronds of the weedy sea dragon – the list is as endless as a fractal.

I’m not very good at mathematical writing but the best way to explain it that I’ve found is an article by Dave Dewey Introduction to the Mandelbrot Set - A guide for people with little math experience.

 identical to the whole. In fact, the Mandelbrot set is infinitely complex. Yet the process of generating it is based on an extremely simple equation involving complex numbers.

Fractals are a lot of fun for kids and there are a number of free on-line generators such as Easy Fractal Generator and  Fractal Poster.

Another good place to go is You Tube where in a series of 6 videos science fiction author Arthur C Clarke introduces the Mandelbrot set



Mathematics, Magic and Mystery


I love maths. Specifically I love numbers the way some people feel about art, music and literature. I love words too and most of my friends and family understand that but very few understand my fascination with mathematics.

It’s all about patterns and the concept of infinity – the thrill of a proof that falls into place or knowing a problem has taken to its infinite end. I first discovered the patterns when I learned to count and realised I could just keep going. Numbers were infinite and because there was a pattern to the way they were incremented, I could count all day if I wanted to (and when I was 4 I thought that was heaps of fun).

At school I discovered all sorts of different maths and once again there were patterns to formula, equations and proofs, infinite tendencies to infinity. The mind boggled when I first found out about imaginary and complex numbers. I was four all over again. The possibilities were endless.

At Uni I survived two years of Statistics by applying the patterns and most of the time it worked out right even if I hadn't learned the where and why. I late enrolled in a Maths degree but life got in the way of something I was doing for fun. As an adult maths constricted to become the tedious chore of juggling the budget and for a while the magic disappeared.

Mandlebrot - Mathematics Stack Exchange
Last month was, April 2014, was Maths Awareness Month (MAM), something I discovered thanks to Twitter (‪#‎MathAwarenessMonth‬). The theme for this year was Mathematics, Magic and Mystery, a tribute to mathematics writer Martin Gardner, “whose extensive writings introduced the public to hexaflexagons, polyominoes, John Conway’s Game of Life, Penrose tiles, the Mandelbrot set, and much more. “ (http://www.mathaware.org/index.html ) 2014 is the centenary of his death.


During MAM, I was too preoccupied following up on the wonderful maths relating posts that were appearing in cyberspace to blog about them but I intend to do something about that beginning with The Mandelbrot Set, which is the best way I can find to explain why I like maths.
