All men are mortal. Socrates is a man. Therefore, Socrates is mortal. Logical arguments like this one have been studied since antiquity. In the last few decades, however, logic research has changed ...

A team of researchers at Aalto University in Finland has found a way to use nanowires to build all-optical logic gates—a major step toward building a light-based computer. In their paper published in ...

A couple of weeks ago, I wrote an article about a digital and analog circuit simulator called ksimus. One of my readers asked what the difference was between ksimus and ktechlab so I thought I'd take ...

MIT Press recently published Fundamental Proof Methods in Computer Science, a book by Konstantine Arkoudas and David Musser, a professor emeritus of computer science at the Rensselaer Polytechnic ...

Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of ...

A depiction of a logic gate constructed within a gel medium, which is ingeniously formed from three self-trapped beams of light. This innovative approach not only highlights the potential of using ...

Zadeh had observed that conventional computer logic couldn’t manipulate data that represented subjective or vague ideas, so he created fuzzy logic to allow computers to determine the distinctions ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

Remember how Jay Keasling said, “ Don’t be surprised if one day your computer has biological parts “? Well, researchers aren’t there yet, but they’re getting closer, as John Timmer details over at Ars ...
