摘要

A few thousand years ago a Greek philosopher utilized the polished surface of a mineral surface to get his valuable messages across to the public. Although this communication method was convenient at that time it was unpractically and expensive. We find it still nowadays but in a more remote area of humanness communications as it is e.g. for the grave yards.
