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 ...

Gate!, a fun and educational toy that [BKriet] ultimately donated back to the class (that’s a hot move in our book). ... Here’s a big set of PCB logic gates, but really, ...

Using DNA and harmless gut bacteria, scientists at Imperial College London have built biological logic gates that could lead to the development of a new generation of microscopic biological ...

Logic gates take two inputs, compare them, and then output a signal based on the result. They can, for example, output a 1 if both incoming signals are a 1 or a 0, or if either or neither of them ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...

Logic gates process information that we call bits, which come in the form of 0s and 1s. To create the fastest logic gate ever, the researchers used two synchronized laser pulses as the input signals.

A chip that contains one logic gate or a small number of logic gates. Although thousands of gates are routinely placed on a single chip, discrete logic chips with only one or two gates are also ...

A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 ...

Boolean algebra is the combination of logic and algebra, initially developed by George Boole, for whom the subject is named, in the 1840s and '50s, and later refined by other logicians through the ...
