A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

The concept of optical computing is reintroduced with an important new twist — optical computing not as a digital machine, but as an analog engine able to serve as a hardware accelerator for existing ...

Today, most of what we think of as a computer uses digital technology. But that wasn’t always the case. From slide rules to mechanical fire solution computers to electronic analog computers, there ...

When your only tool is a hammer, everything starts to look like a nail. That’s an old saying and perhaps somewhat obvious, but our tools do color our solutions and sometimes in very subtle ways. For ...

In 1961, the best general purpose desktop computer money could buy was the Pace TR-48. At just 400 pounds and $25K, the only downside was that it was a little tough to program. That's because the ...

Editor’s Note: This article came about from another article called “Circuits without wires” in which a comment by Arthur Glazar led to my discovery of this gem of an article, thanks to my colleague ...

A new study shows that metamaterials can be designed to do "photonic calculus" as a light wave goes through them. A light wave, when described in terms of space and time, has a profile that can be ...

The Antikythera Mechanism was salvaged out of a shipwreck in 1900. It's the original HotHardware -- the first known example of an analog computing device. Scientists estimated it was made in 100 BC.

Could updated analog computer technology – popular from about 1940-1970 –be developed to build high-speed CPUs for certain specialized applications? Researchers at the Defense Advanced Research ...
