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 understand ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Cells of all organisms process numerous signals originating from the internal biological processes or from the environment to produce the appropriate cellular response. Designed gene regulatory ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

Digital gates are fundamentally analog in nature. They use transistors. Sure, these transistors are operated at their conduction extremes (which is why they are called “digital”), but during the logic ...

Electronics is the manipulation and processing of information using electrons, so it shouldn’t be hard to imagine what the emerging field of atomtronics is attempting to do. The idea is to manipulate ...

Oscillators, also called astable multivibrators, are electronic devices that generate a periodic signal. They are employed in a large number of applications such as clocks, oscillophones, musical ...
