Book Description
A scurrilous newspaper has built up a large following by publishing details of political and sexual scandals. It is remarkably well-informed and has therefore created a whole host of enemies. When the editor is killed and the printing press smashed to bits, the Invisible Detectives are hired by the man who financed the production of the paper. He wants the killer brought to justice and the scandal sheet revived. Peter and Paul Skillen find themselves in great danger as they unearth an enormous amount of scandal and corruption before the villains are brought to book.

Book Description
How many people achieve a cult following because of their writing in mathematics? Only a handful, and Martin Gardner is among the most well known and well loved. Not only did he present a notoriously difficult subject in an engaging and accessible way, but in doing so, he attracted an incredibly broad readership. His correspondents ranged from academics like Roger Penrose and John Horton Conway to artists MC Escher and Salvador Dali to writer Isaac Asimov. His "Mathematical Games" column in Scientific American ran nearly every month for 26 years and was one of the most popular in the magazine's history. Gardner would have celebrated his 100th birthday this October, and to mark the occasion we've created this eBook collection, Martin Gardner: The Magic and Mystery of Numbers. In this anthology, we strove to create a new "slice" through his wealth of material. Here, we focus on all flavors of number, from common integers and negative numbers to figurate numbers and the exotic random number, Omega, which can be described but not computed. Some of these columns are less well known than, say, his writings about flexagons, but they are no less fun. In true Gardner fashion, they leap from magic and games—as well as art, music, and literature—to flashes of deep mathematical insight. Lattice integers become a billiards challenge and surreal numbers spawn a host of related games. The "abracadabric number e," quoting French entomologist Jean-Henri Fabre, leads to spiders' webs and compounded interest. The binary Gray code inspires a poem and cracks the classic Chinese Rings puzzle. And binary numbers unlock mind-reading tricks and the Tower of Hanoi. Almost every column offers up problems for readers to solve and test their understanding—along with the answers for anyone easily frustrated. We hope that they will prove as inspirational to readers now as they did to earlier audiences.

Book Description
Rome, 1221. On the death of Dominic Guzman, founder of the Order of Dominican Friars, a list of three names is locked away with the depositions attesting to Dominic's beatification, and a copy is sealed in an icon of the Virgin Mary that is eventually carried to New France. This list is the thread that binds the fates of ordinary people caught up in the grand sweep of historical events. The Madonna List traces the lives of two nineteenth—century men across three continents, where each finds himself intertwined with a woman who has been visited by the Virgin Mary. Bernad Birous is an ambitious and arrogant young Genoan of the merchant class who desires to use the power of the Church to serve his worldly aims, and who comes to believe that he is the chosen of God. Martin Goyette is a young artist from the rural parishes of Lower Canada who becomes enmeshed in the doomed Lower Canada Rebellion of 1838. Their very different lives are drawn together in a penal colony in New South Wales (Australia), where fortune, ambition, and faith determine their fates. A web of mystery, violence, love, betrayal, and tragedy finally leaves one man standing and one broken when the shattering secret of The Madonna List is revealed.

Book Description
Today complex numbers have such widespread practical use--from electrical engineering to aeronautics--that few people would expect the story behind their derivation to be filled with adventure and enigma. In An Imaginary Tale, Paul Nahin tells the 2000-year-old history of one of mathematics' most elusive numbers, the square root of minus one, also known as i. He recreates the baffling mathematical problems that conjured it up, and the colorful characters who tried to solve them. In 1878, when two brothers stole a mathematical papyrus from the ancient Egyptian burial site in the Valley of Kings, they led scholars to the earliest known occurrence of the square root of a negative number. The papyrus offered a specific numerical example of how to calculate the volume of a truncated square pyramid, which implied the need for i. In the first century, the mathematician-engineer Heron of Alexandria encountered I in a separate project, but fudged the arithmetic; medieval mathematicians stumbled upon the concept while grappling with the meaning of negative numbers, but dismissed their square roots as nonsense. By the time of Descartes, a theoretical use for these elusive square roots--now called "imaginary numbers"--was suspected, but efforts to solve them led to intense, bitter debates. The notorious i finally won acceptance and was put to use in complex analysis and theoretical physics in Napoleonic times. Addressing readers with both a general and scholarly interest in mathematics, Nahin weaves into this narrative entertaining historical facts and mathematical discussions, including the application of complex numbers and functions to important problems, such as Kepler's laws of planetary motion and ac electrical circuits. This book can be read as an engaging history, almost a biography, of one of the most evasive and pervasive "numbers" in all of mathematics.

Book Description
Designed to help pre-service and in-service teachers gain the knowledge they need to facilitate students' understanding, competency, and interest in mathematics, the revised and updated Second Edition of this popular text and resource bridges the gap between the mathematics learned in college and the mathematics taught in secondary schools. Highlighting multiple types of mathematical understanding to deepen insight into the secondary school mathematics curriculum, it addresses typical areas of difficulty and common student misconceptions so teachers can involve their students in learning mathematics in a way that is interesting, interconnected, understandable, and often surprising and entertaining. Six content strands are discussed—Numbers and Operations; Algebra; Geometry; Measurement; Data Analysis and Probability; and Proof, Functions, and Mathematical Modeling. The informal, clear style supports an interactive learner-centered approach through engaging pedagogical features: Launch Questions at the beginning of each section capture interest and involve readers in learning the mathematical concepts. Practice Problems provide opportunities to apply what has been learned and complete proofs. Questions from the Classroom bring the content to life by addressing the deep "why" conceptual questions that middle or secondary school students are curious about, and questions that require analysis and correction of typical student errors and misconceptions; focus on counter intuitive results; and contain activities and/or tasks suitable for use with students. Changes in the Second Edition New sections on Robotics, Calculators, Matrix Operations, Cryptography, and the Coefficient of Determination New problems, simpler proofs, and more illustrative examples Answers and hints for selected problems provided
