Four colors suffice : How the map problem was solved
Robin J. Wilson (Author), Ian Stewart
"On October 23, 1852, Professor Augustus De Morgan wrote a letter to a colleague that described a problem posed by a former student of his: What is the least possible number of colors needed to fill in any map (real or invented) so that neighboring countries are always colored differently? Providing a clear and elegant explanation of the problem and the proof, Robin Wilson tells how a seemingly innocuous question baffled great minds and stimulated exciting mathematics with far-flung applications. This is the entertaining story of those who failed to prove, and those who ultimately did prove, that four colors do indeed suffice to color any map. This new edition features many color illustrations. It also includes a new foreword by Ian Stewart on the importance of the map problem and how it was solved."--from the back cover
