Atoms can be stacked in different ways to create a variety of simple lattice types. There are three common types of lattice structure that most metals belong to (Fig. 4.1): face-centred cubic (fcc), body-centred cubic (bcc) and close-packed hexagonal (cph)....

It would have been relatively easy for a person with knowledge of metals to melt down bronze objects and forge them into, oh, say, coins—bronze was used to make money back then—or mold the bronze into anything else of value, for that matter.We're very fortunate that the device ended...
