A Great Physicist's Visions of a Future for Tiny Objects

One of my favorite Feynman contributions is a now-legendary talk entitled "There's Plenty of Room at the Bottom," which he delivered at Cal Tech in 1959. You can easily find it online. The "plenty of room" that Feynman referred to is the possibility of putting lots of information, and lots of action, into very small spaces. In the years since, parts of his vision have been realized and surpassed, but not all of it. His central insight, simple yet profound, was that atoms, though very small, are usable building blocks.
