Ralph Merkle, Robert Freitas and others have a theoretical design for a molecular mechanical computer that would be 100 billion times more energy efficient than the most energy efficient conventional ...

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 ...

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 ...

Mechanical keyboards can turn typing into a premium experience, but picking the right one takes some care. Here are eight ...

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 ...

The mechanical computers of yesterday may have been enormous, difficult to program, and amazingly clunky—but they sure were beautiful to watch in action. Released theatrically by Popular Science on ...
