Editing Chinese mathematics (section)

== Qin dynasty ==
Not much is known about [[Qin dynasty]] mathematics, or before, due to the [[burning of books and burying of scholars]], circa 213–210 BC. Knowledge of this period can be determined from civil projects and historical evidence. The Qin dynasty created a standard system of weights. Civil projects of the Qin dynasty were significant feats of human engineering. Emperor [[Qin Shi Huang]] ordered many men to build large, life-sized statues for the palace tomb along with other temples and shrines, and the shape of the tomb was designed with geometric skills of architecture. It is certain that one of the greatest feats of human history, the [[Great Wall of China]], required many mathematical techniques. All Qin dynasty buildings and grand projects used advanced computation formulas for volume, area and proportion.

Qin bamboo cash purchased at the antiquarian market of [[Hong Kong]] by the [[Yuelu Academy]], according to the preliminary reports, contains the earliest epigraphic sample of a mathematical treatise.
