Wikipedia:Articles for deletion/Rational trigonometry
Contrary to the nomination statement, there *are* reliably published third party sources: The New Scientist article, and the MAA review. However, the sources are all about the event of the book's publication, their existence does not distinguish this book from an enormous number of other mathematics books, and our article is not actually focused on the book but on its contents. I think the most relevant guideline is : this theory made a brief popular media splash when it appeared, but has not been demonstrated to have the enduring notability required to make it an encyclopedic topic rather than a news topic. Incidentally, the idea of simplifying certain calculations by using squared distances rather than Euclidean distances is a very useful one, but is far older than Wildberger's work (e.g. Cayley wrote about squared distances in 1860), so the usefulness of this idea cannot be used as a justification for keeping an article focused on Wildberger's contributions: it's not his contribution, even if he briefly popularized it
