Vacuum tube technology is making a comeback, with physicists hoping to use miniature 'vacuum transistors' to make increasingly-smaller computers. The development comes just as the laws of physics are ...

A vacuum tube, known as the first electronic device, is used to switch, amplify, or commutate electric signals. In the past, vacuum tubes functioned as a main part of a diverse range of electronic ...

The transistor revolutionized the world and made the abundant computing we now rely on a possibility, but before the transistor, there was the vacuum tube. Large, hot, power hungry, and prone to ...

The transistor is one of the most profound innovations in all of human existence. First discovered in 1947, it has scaled like no advance in human history; we can pack billions of transistors into ...
