The enduring luster of gold, the conductivity of copper, the strength of steel—the special properties of metals have reshaped societies and defined eras; they have such an important role in human history that entire have been named after them.
Although it sometimes requires taking minute samples of an object, even that damage may be unacceptable for some artifacts.
The new method does not involve removing a sample of the object.
And how have metals enabled our modern hi-tech world?
