Some people though that mathematics is fun, challenging, or brain-tearing, but how about beautiful?

Some of you may have already know about fractals – a geometry so elaborate that in any scale of magnification, the shape is still basically the same. A non-ideal example is trees: zooming in (looking at the branches) gives you a “mini-tree” shape; do that again and you get more mini-mini-trees, and so on. Real fractal trees look like trees even when you zoom in infinitely many times. Read more »
