Transistors are at the heart of every gadget — but as futurist Ray Kurzweil once predicted, "Our computers aren't going to be these distinct rectangular devices we carry around. We are going to merge ...

AI machine learning uses so much computing power and energy that it's typically done in the cloud. But a new microtransistor, 100X more efficient than the current tech, promises to bring new levels of ...

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 ...

Did you know that the first half of the 20th century was dominated by vacuum tubes? Be it radio, television, telephone networks or computers, vacuum tubes were the basic component for all electronics.

Way back in the salad days of digital computing (the 1940s and '50s), computers were made of vacuum tubes -- big, hot, clunky devices that, when you got right down to it, were essentially glorified ...
