At one time a scientist or engineer trying to solve a tough problem with electronic computation had the choice of an analog computer, a digital computer, or both together in a hybrid configuration.

(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...

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 ...

Our new tech editor for Analog looks at the evolution of “analog” and how it inadvertently spun off a pop music genre. Operational Amplifiers are exactly that—amplifiers that can perform mathematical ...

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 ...

The ancient question of whether or not it’s possible to construct a circle with the same area as a given square using only a drawing compass and straightedge was finally answered in 1882, where it was ...

"But take away the fancy GPS shells and the AGS, and its digital fire control system are no more accurate than mechanical analog technology that is nearly a century old." Yeah, and take away the fancy ...
