They're at the grocery checkout. They kill cancer cells. They're in pointers that drive cats crazy and in the fiber networks that connect us to the internet. Lasers are so ubiquitous it's hard to imagine a world without them. So you'd think we would know who the inventor was, right? Turns out it's not so easy. There's the guy who wrote down the initial idea, two other guys who got a patent for it, and then another guy who actually built the first laser. We spoke to Nick Taylor, author of Laser: The Inventor, the Noble Laureate, and the Thirty-Year Patent War about this story and what it tells us about how inventions happen.
