(Phys.org)—A team of scientists from several research centers in South Korea, has succeeded in building a logic circuit that is based on switchable magnetism, rather than electronics. They describe their research and a ...
(Phys.org)—By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to ...
