We’ve often said you can make a logic gate out of darn near anything. [The Action Lab] agrees and just released a video showing how he made some logic gates from chains and gears. Along the way, he ...

Phononic crystals (PnCs) are sophisticated materials distinguished by their periodic arrangement of inclusions, which effectively manipulate the diffusion of elastic and acoustic waves. These ...

With transistors and logic gates as our basic building blocks, we can begin to construct the actual circuits that make up computer memory. One of the simplest memory circuits is the AND gate, which ...
