A contemporary philosopher who is also a close friend once said to me. "It is utterly impossible for any human mind to both believe in god and understand the Mandelbrot set".
The Mandelbrot set is the most complex mathematical entity ever invented by a human mind and yet it is an entity of the most exquisite simplicity and very easily understood. A child can understand the Mandelbrot set.
I won't post a link because I don't know how to but there is plenty of source material online. If knowledge doesn't scare you look it up.
