There is something we find beautiful about
The most famous fractal is probably the Mandelbrot set, named for Benoît Mandelbrot, the French-American mathematician who coined the term "fractal" in 1975. The Mandelbrot set is a 2-dimensional object created through a mathematical equation. Mathematicians had first pondered how to turn it into a 3-dimensional object, a "Mandelbulb," more than 20 years ago, but they didn't figure out how to do it until recently. The result is above. Quite pretty, don't you think?
