For example, [[bronze]] is the alloy of [[copper]] and [[tin]].  Alloy creation played an important role in early human [[history]]: the discovery of the value of bronze, for example, spurned an increase in human tool development and metallurgy, spurning cultural, scientific, and technological advances. This period of history, known as the [[Bronze Age]], occurred very early in the history of the world.  Another important alloy, [[steel]], has defined the modern [[Industrial revolution|industrial era]].
