Old Babylonian Mathematics and Plimpton 322
A series on the remarkable mathematics from the Old Babylonian period from 1900 B.C.E to 1600 B.C.E. This culture had a rich mathematics that we are just now learning more and more about. Their sexagesimal arithmetical system is powerful and unique, but there were other aspects to their mathematics that are well worth learning about.
This series is presented by Daniel Mansfield and N J Wildberger. One of the main aims is to explain our new understanding of the famous tablet Plimpton 322 as the world's first and most exact trigonometric table! Along the way we will learn quite a bit about this culture and its mathematical thinking.
