About 10 years ago, Mark Changizi started to develop research on human vision and how it could see changes in skin color. Like many academics, Changizi, an accomplished neurobiologist, went on to pen a book. The Vision Revolution challenged prevailing theories–no, we don’t see red only to spot berries and fruits amid the vegetation–and detailed the amazing capabilities of why we see the way we do.
If it were up to academia, Changizi’s story might have ended there. “I started out in math and physics, trying to understand the beauty in these fields,” he says, “You are taught, or come to believe, that applying something useful is inherently not interesting.”
