"Of immense interest to those who enjoy recreational maths and puzzles . . . even the most hardened puzzler will find something new." -- Mathematical Gazette Puzzles are as old as history itself, following an arc like that of technology: centuries of slow progress, followed by rapid expansion in the 1800s, and an explosion of activity in the twentieth century. This collection by bestselling author David Wells, a Cambridge math scholar and teacher, follows that pattern. Its first part is devoted to puzzles from ancient Egypt and Babylon and subsequent sources, featuring those devised by Lewis Carroll, Eduard Lucas, Sam Loyd, and other master puzzlers of the Victorian era. The second part demonstrates the tremendous variety of twentieth-century puzzles. More than 560 puzzles are included, from the "mind sharpeners" of a medieval monk to the eighteenth-century Ladies' Diary, the Hindu Bhakshali manuscript, and riddles and popular rhymes. None requires any mathematics beyond the most elementary algebra and geometry -- and few require even that. Complete answers appear at the end.

The walking dead from 15 centuries haunt this compendium of ghostly visitations through the ages, exploring the history of our fascination with zombies and other restless souls. Since ancient times, accounts of supernatural activity have mystified us. Ghost stories as we know them did not develop until the late nineteenth century, but the restless dead haunted the premodern imagination in many forms, as recorded in historical narratives, theological texts, and personal letters. The Penguin Book of the Undead teems with roving hordes of dead warriors, corpses trailed by packs of barking dogs, moaning phantoms haunting deserted ruins, evil spirits emerging from burning carcasses in the form of crows, and zombies with pestilential breath. Spanning from the Hebrew scriptures to the Roman Empire, the Scandinavian sagas to medieval Europe, the Protestant Reformation to the Renaissance, this beguiling array of accounts charts our relationship with spirits and apparitions, wraiths and demons over fifteen hundred years, showing the evolution in our thinking about the ability of dead souls to return to the realm of the living—and to warn us about what awaits us in the afterlife.
