Using Science to Achieve Invisibility

Clip: Season 46 | 3m 21s | Video has closed captioning.

How do we see objects? By intercepting waves of light bouncing off of them and into our eyes, each reflected at a different angle. One way to achieve invisibility is to bend the paths of light using lenses, mirrors, or metamaterials with unique reflective properties. There are a lot of problems still to be solved—and valuable applications awaiting those who succeed.
