You are welcome ^^

If you need help with math let me know :D

The butterfly in the Lorenz system refers to the shape of the chaotic attractor which looks like a butterly. The story about the butterfly wings that make a small initial differences or inexactness which then causes hurricane is not why the butterfly attractor is called the butterfly attractor. However the phenomenon driving the butterfly story is what drives the chaos in the butterfly attractor.

I hope that wasn't too confusing :3
