The Klein Project aims to present contemporary mathematics for secondary school teachers. Klein Project materials are intended to inform, entertain and feed the enthusiasm of secondary teachers for their subject.

A “Klein Vignette” is a short piece of writing about a single mathematical topic. It assumes the reader has some undergraduate mathematical knowledge, and at least a willingness to engage with mathematical writing. Klein Vignettes are not just “about” mathematics, they contain significant mathematics which is likely to be new to most secondary teachers.
