These talks will be self-contained presentations of mathematical concepts and theorems. They are intended to be accessible to all mathematics students. Coffee, tea and drinks will be provided.

A research topic causing some hot debate in the field of mathematics education is Ethnomathematics - relationships between culture and mathematics. Once strand of the research is historical, another is sociological, but the one for this lunchmaths is the anthropological strand. Researchers claim that artefacts such as indigenous maps, string games, and weaving patterns result from mathematical activities. The problem for those of us in mathematics education is how best to use ideas about ethnomathematics in improving mathematics teaching. At the heart of this problem is the question in the title.
