What wrapping a rope around the Earth reveals about the limits of human intuition
If you tied a rope tight around the Earth’s equator and then added a single yard of slack, would the extra material make any noticeable difference to someone standing on the ground?

original Yes, actually.

(The video format is incompatible with NewsTalkers. It's short - 6 minutes - and very worthwhile.)

The answer comes as a surprise to most people, but the additional bit of rope raises it high enough off the ground for our eyes to easily discern it, and our feet to easily trip over. That fact might seem trivial, but the early 20th-century philosopher Ludwig Wittgenstein believed that this chasm between human intuition and physical reality revealed something important about the fallibility of our thinking. 

After all, if something that seems obvious to almost everyone can be totally false, what else might we be wrong about? 

This video from the Center for Public Philosophy at the University of California, Santa Cruz breaks down the mathematics behind Wittgenstein’s knotty example, and asks whether it should make us all feel a bit less certain about even our most deeply held beliefs.
