THOMAS EDISON LIKED to say that he never failed. He succeeded every now and again with an invention that would change the world. The rest of the time, he tried thousands of other things with only one fault—that they would never work.

Ranking innovations is more art than science. Modern inventions tend more toward improving than transforming: an app that connects the world in a better way, planes that fly farther, faster.
