TELEPHONE
Alexander Graham Bell invented a technology that would later bear his name. But how much did he deserve it?
The problem that Bell solved was to turn electrical signals into sounds.
Philip Reis had already designed a sound transmitter in 1860, and Hermann Ludwig Ferdinand von Helmholtz had already built a receiver. Bell's real contribution was "to vary the strength of the current to capture variations in voice and sound," Lemley writes.
He was racing against Thomas Edison. Even Bell's final product -- which combined transmitter, fluctuating current, and receiver -- had company.

THE AUTOMOBILE
The car industry represents the epitome of incremental innovation. Take a tricycle. Add an engine. You've got a car. (Just look at the picture of the the original Benz Motorwagen from 1885).
Condensing the invention of cars to those six words leaves out a lot of detail and a few m...

COTTON GIN
The fabric cotton comes from cotton fibers that mix with seeds in the pods of cotton plants. To make the fabric, therefore, you have to separate the fibers from the seeds.
