Envision the world in 11 dimensions: A TED-Ed lesson to blow your 3D mind

Posted by:

In our three-dimensional world, all we can experience is length, width and height. Unless one of your friends is a hypercube, it’s hard to imagine just what it would look like to live beyond the 3D. Would you like it? Would you understand it? Would you even believe it was real?

In this spunky TED-Ed lesson, Alex Rosenthal and George Zaidan lead us into a mathematical playland and test the very limits of our imagination. Inspired by Edwin Abbott’s 1884 novella Flatland, they offer one way to conceive of a fourth, fifth or 11th dimension, and challenge us to open our eyes to a world outside what we’re built to perceive.
