The Transistor

The transistor is one of two most important inventions of the last century. Without the transistor’s invention, most of the electronic devices on which you’re so hopelessly dependent would not exist. The modern age rely on the transistor – personal computers, televisions, smartphones, tablets, phablets, laptops, routers and foot massagers suffused with billions of them.
Transistors are to electronic devices what cells are to our bodies.
