Old Babylonian Mathematics and Plimpton 322
Daniel Mansfield and N J Wildberger's new paper which gives a new interpretation to Plimpton 322 has appeared on Aug 24 in Historia Mathematica online via Science Direct to huge international interest, including the New York Times, Science Magazine, The Guardian, The Times India, Le Monde, Newsweek and hundreds of other papers and journals around the world. Plimpton 322 is a famous Old Babylonian (OB) clay tablet from the time of Hammurabi around 1800 B.C.E. containing 15 rows of Pythagorean triples, such as (119, 120, 169). In our paper, entitled Plimpton 322 is Babylonian exact sexagesimal trigonometry, we give a dramatic new interpretation of what this tablet was originally intended to be. This repositions not only the history of trigonometry but also the role of OB mathematics. And it reveals rational trigonometry to have deep roots in antiquity. You can learn more about our work in the YouTube series Old Babylonian Mathematics, the first video of which is here. 
The Wild Egg Team
Wild Egg Pty Ltd (ABN 25107619787) is a small Australian company aimed at mathematics education across a wide spectrum. It is particularly focused on Rational Trigonometry, how to promote a more computational and logically solid foundation for undergraduate mathematics, and supports N J Wildberger's YouTube channel Insights into Mathematics. It is based in Sydney and directed by A/Prof N J Wildberger, a pure mathematician, with assistance from Krista Ruffolo, an engineer turned mathematics educator.
Wild Egg has published the best selling and highly original book Divine Proportions: Rational Trigonometry to Universal Geometry. This book outlines a new approach to the education and use of trigonometry. Wild Egg also provides a comprehensive selection of screenshot pdfs that cover many of Norman's YouTube Playlists: including MathFoundations, WildLinAlg, UnivHypGeom, AlgTop, DiffGeom and more. It will soon offer coordinated audio podcasts to make it easier to access and learn from Wildberger's hundreds of lectures.
Our approach to mathematics is rigorous, conceptual and computationally focussed, and elevates mathematical precision and understanding to new levels. We believe that mathematics should be grounded on a firm bedrock of explicit examples and concrete computations, and that students learn best when each step is careful, clear and concise.
In addition, Wild Egg is excited to be developing the world's first Algebraic Calculus One course, which will be hosted online at OpenLearning and is sure to be a fascinating and powerful addition to undergraduate mathematics education! We will be announcing more about this in the near future, but you can join us by becoming a Patron of Norman's YouTube channel at patreon.com.
