I made this years ago, but just realised it is not on this blog.
It contains snippets of bits of maths from 500BC up to the present day to adorn your classroom or corridor. The focus is on interesting, but accessible maths rather than historical completeness! Mostly inspired by the excellent Alex’s Adventures in Numberland (Alex Bellos) as well as Number Freak (Derrick Niederman)
Best printed A3 in colour. Here is the whole thing as a pdf, and here as a word doc
