Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits.
