Introversion

When you find an impossible number
And multiply it by itself plus a constant number
You get another impossible number.
Keep doing it and you get a set.
The set doesn't exist. But it has meaning.

It's called a Mandelbrot set.
Mandelbrot means a type of bread
Because 'brot' is bread in German.
But that's just his name.

When you keep calculating numbers in the set, you find that it collapses
into itself. Put the numbers on a cartesian plane
With y and x axes

And you get a picture. Like this one.

It's a fractal.

It has no boundaries, because the more you look into it
The more you find.
