In a world filled with things, you might think that settling on what the most important thing of all would be rather difficult. That, however, isn’t the case.
Modern innovation is solely dependent on the transistor and it’s invention and continual improvement thanks to Moore’s law. For those of us unfamiliar with this modern engineering marvel, it is a three-terminal solid-state electronic device. In essence, it allows us to control the current or voltage between two of the terminals by applying an electric current or voltage to the third terminal. For non-engineers, this functionality may seem befuddlingly simple to be the root of all modern innovation, but yet, that is the case – for many fascinating reasons.
Amplifiers, computers, cell phones, nearly everything electronic relies on this three terminal electrical invention. The three-terminal aspect...
