The search for lost technologies

For centuries, historians and scientists have bemoaned the loss of ancient technologies such as Greek fire and Damascus steel. In an article for io9.com, Alasdair Wilkins discusses both lost technologies, as well as the lost Apollo mission schematics.

Wilkins writes:

Greek fire. Damascus steel. These are two technological innovations whose secrets are said to be lost to time. Even the original schematics for the Apollo missions have disappeared into the mists of history, forever hidden inside hopelessly obsolete computers. How do we lose technologies that were once so important? Some say that they aren't really lost, and are working on rediscovering them.
