The Transistor Turns 65

The humble transistor turns 65 this weekend. The tiny device is the solid state descendant of the vacuum tube (or "valve" in the UK), and was used in radio and audio amplifiers. Now the equivalent of many millions of transistors are present in every central processing unit in cars, washing machines, smartphones and computers.

65 years ago William Shockley, John Bardeen and Walter Brattain ... worked together to create the world's first point-contact transistor, a direct precursor to the electronic component that powers every thing from radios and microwaves, to super computers and smartphones.
