HI! I'm in need of some help to come with an interesting physics-related topic for a short, five-minute presentation. We'll be graded by our ability to speak well rather than our physics knowledge, so I want to talk about something simple, straight-to-the-point and not too much technical (no quantum-related topics!).
My initial thought was to talk about evolution of timekeeping devices, but then I thought it is too dense of a topic and more related to History than Physics.
Anyway, some insights about a cool topic would be greatly appreciated!
