Old Babylonian Mathematics and Plimpton 322
In breaking news, 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. 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 course, which will be hosted online and is sure to be a fascinating and powerful alternative to current fashions in undergraduate mathematics education! We will be announcing more about this in the near future.

A/Prof Norman Wildberger (Director)
N J Wildberger is a leading pure mathematics researcher and probably one of the world's most innovative and wellknown mathematical educators. With a BSc (University of Toronto 1979) and PhD (Yale University 1984), he has taught at Stanford University, the University of Toronto, and is currently in the School of Mathematics and Statistics at UNSW Sydney in Australia. He has an influential YouTube channel, several MOOCs, has helped make PD courses for teachers, and has contributed to the direction of the new senior mathematics curriculum in Australia. He is particularly interested in online education as well as the foundational basis of mathematics. Research / Teaching / MOOCs / YouTube / PD courses
