Mystery
Ice fractal
The mathematics of chaos theory have been used to describe and model various aspects of the natural world (infamously, weather prediction) for the last four decades or so. The Mandelbrot Set is one of the most famous fractal patterns arising from these enquiries. I was amazed and delighted to find an echo of that man-made pattern (bottom left) appearing in the surface of a frozen loch.
