Ask a friend to draw a triangle — the one that comes immediately to their mind’s eye on hearing the word “triangle”. This is an experiment proposed by Eleanor Robson in her article Words and Pictures. What are the results? Do we differ from the ancient Mesopotamian scribe … or from each other?
Robson is arguing that even so basic a concept as a triangle is, in part, culturally determined. Are there modern cultural differences in the triangle, or other basic mathematical concepts?
