A steel bar pivots. A spring stretches. Then, with a small shove, the whole setup flips into a new state and stays there until the next push. “We typically think of memory as something in a computer ...

Today, if you want to teach kids the art of counting to one, you’re going to drag out a computer or an iPad. Install Scratch. Break out an Arduino, or something. This is high technology to solve the ...

Researchers have developed a kirigami-inspired mechanical computer that uses a complex structure of rigid, interconnected polymer cubes to store, retrieve and erase data without relying on electronic ...

To the uninitiated like me, it would seem that a “fire control” computer used by the United States Navy in 1953 must have had something to do with extinguishing blazes that would break out onboard a ...

In the 19th century, British mathematician Charles Babbage invented the “difference engine,” a mechanical computer that had an enormously complex arrangement of levers, ratchets and gears. Had this ...
