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 surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is steered ...
