We live in a democracy in which we all have a chance to vote. But does voting mean that the views of the majority are truly represented when it can be shown (mathematically) that all voting systems have flaws? In this talk we use mathematics to look at these flaws and answer associated questions (eg. voting trends and gerrymandering). For a bit of light relief we will see how the same principles work in the Eurovision Song Contest.A lecture by Chris Budd OBE, Gresham Professor of Geometry 12 NovemberThe transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/maths-and-votingGresham College has been giving free public lectures since 1597.
