The Penguin Book of Curious and Interesting Puzzles by David Wells pdf free download. To puzzle and be puzzled are enjoyable experiences, so it is no surprise that puzzling problems are as old as history itself, and follow a similar pattern of many centuries of slow progress, followed by rapid expansion in the nineteenth century, and an explosion in the twentieth. This book follows that pattern. The first third is devoted to puzzles from the dawn of history, in Egypt and Babylon, up to the nineteenth century.
