Maths Clock: Telling time isn't easy

When we started learning how to tell time when we were young, we may have thought it was easy. Now maybe if we had started with the maths clock (image below), we would have thought otherwise.

I first saw this clock via my Twitter feed. It was first posted by @Frauenfelder and re-tweeted by @zen_habits.

This clock would really be a perfect gift for those who are serious mathematics enthusiasts.

Probably they should also make it into a watch. That way, whenever someone asks for time, you can show it to them… That way, you can safely assume that they won’t ever ask you for time again.
