Photoelectric Effect Explained | Perimeter Institute for Theoretical Physics

Digital cameras, small enough to be embedded in our phones, have transformed photography and changed how we interact with the world and each other.

But did you know that this sophisticated piece of modern technology has its roots in the science that won Einstein a Nobel Prize?

Most smartphones today use a sensor called a complementary metal oxide semiconductor or CMOS. It's similar to a CCD or charge coupled device and works because of this one weird trick physicist discovered more than a century ago.

This video discusses how quantum mechanics, once an esoteric flight of fancy, now plays a role everywhere we look.
