Logic gates can be combined to perform any computation. There are millions of them in a computer chip. But let’s see a very simple application of the AND gate.

YouTuber Steve Mould has created a great demonstration of computer logic gates using water, tubes, and 3D printed components. This innovative approach provides a tangible and visual way to ...

Since all logic functions can be made from NAND gates, it should therefore be possible to go as far as to make any device based upon logic, even up to a fully functional computer. He estimates the ...

In this example, the logic gate count will be sum of gate counts of 8-bit multiplier, 16-bit adder and 8-bit subtractors by re-writing it as ((V-G)* á + G). In this example A = 1, C = 3 and B can be ...

“We think of electronic currents as doing computation, but any substrate can act like a computer, including gears, pipes of water, and cells,” Voigt said. “Here, we’ve taken a colony of bacteria that ...

One of the most basic elements of computing is the logic gate, and researchers at Kobe University have turned to the animal kingdom to create a physical model of them — using soldier crabs.

Biological systems have caught the attention of computer scientists, who have been turning everything from RNA molecules to entire bacterial colonies into logic gates. So far, however, these ...
