I first heard about fractals by listening to NPR. One I looked them up I was hooked on their beauty As I continued to research fractals I found out there was a lot to know.
The first thing to know is that fractals come from fractal geometry whose 'father' is Benoit Mandelbrot. There were former mathematicians that had ideas that helped lead to fractal geometry, but it was Mandelbrot who put it all together in the early 19702..
Three of the early mathematicians to know about are Sierpinski, Koch and Julia.
