Many of the problems are drawn from the large number that have entertained and challenged
students guests and colleagues over the years during afternoon tea. The problems have their
roots in many areas of mathematics. They vary greatly in difficulty: some are very easy but
most are far from trivial and quite a few rather hard. Many provide substantial and surprising
results that form the tip of an iceberg providing an introduction to an important topic. To
