In this book, Marijane Osborn translates into modern English nine lively medieval verse romances, in a form that both reflects the original and makes the romances inviting to a modern audience. All nine tales contain elements of magic: shapeshifters, powerful fairies, trees that are portals to another world, and enchanted clothing and armor. Many of the tales also feature powerful women characters, while others include representations of “Saracens.” The tales address issues of enduring interest and concern, and also address sexuality, agency, and identity formation in unexpected ways.

Nine revolutionary algorithms that power our computers and smartphones Every day, we use our computers to perform remarkable feats. A simple web search picks out a handful of relevant needles from the world's biggest haystack. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers, and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? John MacCormick answers this question in language anyone can understand, using vivid examples to explain the fundamental tricks behind nine computer algorithms that power our PCs, tablets, and smartphones.
