Can we create new senses for humans? | David Eagleman
As humans, we can perceive less than a ten-trillionth of all light waves. “Our experience of reality,” says neuroscientist David Eagleman, “is constrained by our biology.” He wants...

We are built out of very small stuff, and we are embedded in a very large cosmos, and the fact is that we are not very good at understanding reality at either of those scales, and that's because our brains haven't evolved to understand the world at that scale. Instead, we're trapped on this very thin slice of perception right in the middle. But it gets strange, because even at that slice of reality that we call home, we're not seeing most of the action that's going on. So take the colors of our world. This is light waves, electromagnetic radiation that bounces off objects and it hits specialized receptors in the back of our eyes. But we're not seeing all the waves out there. In fact, what we see is less than a 10 trillionth of ...
