Invention Of The Transistor By John Bardeen, Walter Brattain And William Shockley In 1947

Almost every piece of equipment that stores, transmits, displays or manipulates information to his heart full of electronics silicon chip. These chips of each house of thousands, even millions of transistors.

The history of the transistor 1800 begins a dramatic scientific discoveries, scientists such as Maxwell, Hertz, Faraday, Edison and electricity could be harnessed for human use. Inventors such as Braun, Marconi, Fleming and DeForest to apply the information for the development of electrical equipment such as radio.

Their work was created by Bell Labs, whose scientists challenge was to use this information to create practical and useful electronic devices for communication. Teams of Bell Labs scientists, such as Shockley, Brattain, Bardeen, and many others .-- responded to this challenge and came up with the information age. They stood on the shoulders of great inventors, to produce 19 century greatest invention of our time: the transistor.

The transistor was invented in 1947 at Bell Labs by a team led by physicists John Bardeen, Walter Brattain and William Shockley. Initially, the team has not been high on the list of possible applications of this little device. This is not surprising that the first computers were built in 1940 and 1950, some scientists have seen in them the seed of a technology that, in just a few decades to penetrate almost all spheres of human life. Before the digital explosion, the transistors are a vital part of improving the existing analog systems, such as radios and stereos.

When it was put in computers, however, the transistor has become an integral part of the dotcom boom. They are also capable of mass-produced by millions sliver of silicon semiconductor chips. And 'this almost unlimited capacity to integrate on-chip transistors, which has fueled the information age. Today, these chips are not only part of the computer. They are also important in many devices such as cameras, cell phones, copiers, jumbo jets, modern cars, manufacturing equipment, electronic scoreboards, video and games. Without the transistor would not have the Internet and space travel.

Years after its creation, the transistor replaced the large, fragile vacuum tubes that had been used to enhance and change the signals. The transistor became the building block of all modern electronics and the foundation for microchip and computer technology.
