A book to celebrate the 150th anniversary of the solution to one of the world's most puzzling mathematical problems. The four-colour theorem states that every map in the world can be coloured with just four colours in such a way that neighbouring countries have different colours. One of the simplest problems to state, one of the hardest to solve, which took a century for mathematicians to prove. This book introduces the mathematicians behind the mathematics, among them a bishop, an astronomer, a botanist, an obsessive golfer and a bridegroom who spend his honeymoon colouring maps.

'A very fine history.his sly wit and infectious enthusiasm make him an entertaining and avuncular guide.' ' The four-colour problem was one of the most famous and controversial conundrums ever known, stumping thousands of ppuzzlers for over a century. It sounded simple: what is the least number of colours needed to fill in any map, so that the neighbouring countries are always a different colour? However, it would take over a hundred years for amateur problem-solvers and mathematicians alike to answer the question first posed by Francis Guthrie in 1852. And, even when a solution was finally found using computers , debate raged over whether this technology could ever provide the proof that traditional pen-and-paper calculations could. This is a gripping story of thhe race to solve the riddle - a tale of dedicated puzzlers, mind-boggling maps, human ingenuity and the great rhombicuboctahedron.'. Size: 8vo - over 7¾" - 9¾" Tall.
