Life, uh, finds a way. And more often than not, that way is analog, not digital. Even the impulse-like action potentials in the brain are more complex than computers’ 1s and 0s — and digital ...

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 ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

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 ...

Researchers from MIT design a new analog compiler (Yes, that's right: analog.) that could pave the way to efficient and accurate simulations of organs and biological organisms. Kristopher Sturgis Last ...

We are big fans of the Falstad circuit simulator. Sure, it isn’t perfect, but there’s nothing else like it when you want to whip up a simple circuit. But we were blown away when we saw a more or less ...

With the incredible variety of projects submitted to our Op-Amp Contest, you’d almost forget that operational amplifiers were originally invented to perform mathematical operations, specifically ...

Celebrated physicist Richard Feynman first proposed it in 1982, and now it exists: the first universal, digital quantum simulator. Austrian scientists, who published how they created the mind-blowing ...

I'm sure nearly everyone has by now heard that Google “proved” the D-Wave 2 they operate jointly with NASA (mainly paid for by Google) can operate “up to ∼ 10 8 times faster”. If not, you might want ...

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 ...
