An analog computer is a system that provides information in continuous form. These computers can only represent physical quantities such as pressure, weight, voltage pressure, speed, and more.

Early computers could perform fairly complex calculations just by arranging a few analog circuits. By choosing appropriate resistor and capacitor values, arithmetic summers, integrators, and ...

Many of the most exciting properties of materials arise due to interactions between electrons. Correlations between electrons' spins are involved in magnetism and may be responsible for ...

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 ...

Analog computers were largely phased out once digital systems began to hit the scene, but they’re still used in certain situations because they’re well-suited to complex simulations. Now, a research ...

Scientists have been working toward developing a novel mathematical approach that will help advance computation beyond the digital framework. Your computer performs most tasks well. For word ...

Physicists have invented a new type of analogue quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve. New research published in Nature ...
