Darkness is falling and only Contessa Sofia can turn the tide in this thrilling final installment of the Wave trilogy. In the 1347th year of Our Lady the engineers of Concord defeated the fractious city-state of Rasenna using the magical science of Wave Technology. The City of Towers fought back, and for a while Concord's plans for domination were halted. But First Apprentice Torbidda regrouped, and reformed Concord to his own design. Now he is in absolute control, and plotting the final battle that will pacify Etruria . . . permanently. Contessa Sofia Scaligeri could rally her people once again, but she is far away in the Crusader Kingdom of Akka, trapped with her son, in thrall to the tyrant Queen Catrina. Darkness is falling. The final battle must be fought and the tide must be turned, lest evil reign forever.

In Crete during World War II, Alenka, a young woman who fights with the resistance against the brutal Nazi occupation, finds herself caught between her traitor of a brother and the man she loves, an undercover agent working for the Allies. May 1941. German paratroopers launch a blitzkrieg from the air against Crete. They are met with fierce defiance, the Greeks fighting back with daggers, pitchforks, and kitchen knives. During the bloody eleven-day battle, Alenka, a young Greek woman, saves the lives of two Australian soldiers. Jack and Teddy are childhood friends who joined up together to see the world. Both men fall in love with Alenka. They are forced to retreat with the tattered remains of the Allied forces over the towering White Mountains. Both are among the seven thousand Allied soldiers left behind in the desperate evacuation from Crete’s storm-lashed southern coast. Alenka hides Jack and Teddy at great risk to herself. Her brother Axel is a Nazi sympathizer and collaborator and spies on her movements. As Crete suffers under the Nazi jackboot, Alenka is drawn into an intense triangle of conflicting emotions with Jack and Teddy. Their friendship suffers under the strain of months of hiding and their rivalry for her love. Together, they join the resistance and fight to free the island, but all three will find themselves tested to their limits. Alenka must choose whom to trust and whom to love and, in the end, whom to save.

The authors present twenty icons of mathematics, that is, geometrical shapes such as the right triangle, the Venn diagram, and the yang and yin symbol and explore mathematical results associated with them. As with their previous books (Charming Proofs, When Less is More, Math Made Visual) proofs are visual whenever possible. The results require no more than high-school mathematics to appreciate and many of them will be new even to experienced readers. Besides theorems and proofs, the book contains many illustrations and it gives connections of the icons to the world outside of mathematics. There are also problems at the end of each chapter, with solutions provided in an appendix. The book could be used by students in courses in problem solving, mathematical reasoning, or mathematics for the liberal arts. It could also be read with pleasure by professional mathematicians, as it was by the members of the Dolciani editorial board, who unanimously recommend its publication.

The interest earned on a bank account, the arrangement of seeds in a sunflower, and the shape of the Gateway Arch in St. Louis are all intimately connected with the mysterious number e. In this informal and engaging history, Eli Maor portrays the curious characters and the elegant mathematics that lie behind the number. Designed for a reader with only a modest mathematical background, this biography brings out the central importance of e to mathematics and illuminates a golden era in the age of science.

Longlisted for the BSHS Hughes Prize 2021 A New Year’s Present from a Mathematician is an exciting book dedicated to two questions: What is it that mathematicians do? And who gets to be called a ‘mathematician’ and why? This book seeks to answer these questions through a series of stories ranging from the beginning of modern mathematics through to the 20th century, but not in a usual, chronological manner. The author weaves her story around major questions concerning nature of mathematics, and links mathematicians by the substance of their ideas and the historical and personal context in which they were developed. Ideal as a gift for anyone with an interest in mathematics, this book gives a powerful insight into mathematical concepts in an easy-to-read-and-digest manner, without trivializing their nature. The attention given to engaging examples, framed within a poetic narrative structure, means that this book can be enjoyed by almost anyone, regardless of their level of mathematical education.

Named a Notable Book in the 21st Annual Best of Computing list by the ACM! Robert Sedgewick and Kevin Wayne’s Computer Science: An Interdisciplinary Approach is the ideal modern introduction to computer science with Java programming for both students and professionals. Taking a broad, applications-based approach, Sedgewick and Wayne teach through important examples from science, mathematics, engineering, finance, and commercial computing. The book demystifies computation, explains its intellectual underpinnings, and covers the essential elements of programming and computational problem solving in today’s environments. The authors begin by introducing basic programming elements such as variables, conditionals, loops, arrays, and I/O. Next, they turn to functions, introducing key modular programming concepts, including components and reuse. They present a modern introduction to object-oriented programming, covering current programming paradigms and approaches to data abstraction. Building on this foundation, Sedgewick and Wayne widen their focus to the broader discipline of computer science. They introduce classical sorting and searching algorithms, fundamental data structures and their application, and scientific techniques for assessing an implementation’s performance. Using abstract models, readers learn to answer basic questions about computation, gaining insight for practical application. Finally, the authors show how machine architecture links the theory of computing to real computers, and to the field’s history and evolution. For each concept, the authors present all the information readers need to build confidence, together with examples that solve intriguing problems. Each chapter contains question-and-answer sections, self-study drills, and challenging problems that demand creative solutions.
