Sudoku X (also known as "Diagonal Sudoku") is a placement puzzle. In this sudokus main diagonals also contain the digits 1 through 9. About Book This book introduces you to the amazing world of Sudoku X puzzles. It will help you understand the rules of this puzzle. This book is perfect for players of all skill levels and ages. You will find 200 exciting puzzles, both for beginners and for professionals. HOW TO PLAY It is a 9x9 grid, partially divided by black cells into compartments. The puzzle is most frequently a 9x9 grid made up of 3x3 subgrids (called "regions"). Some cells already contain numbers, known as "givens". The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 9 exactly once. Main diagonals also contain the digits 1 through 9. Each number in the solution therefore occurs only once in each of three "directions".

Many students have trouble the first time they take a mathematics course in which proofs play a significant role. This new edition of Velleman's successful text will prepare students to make the transition from solving problems to proving theorems by teaching them the techniques needed to read and write proofs. The book begins with the basic concepts of logic and set theory, to familiarize students with the language of mathematics and how it is interpreted. These concepts are used as the basis for a step-by-step breakdown of the most important techniques used in constructing proofs. The author shows how complex proofs are built up from these smaller steps, using detailed 'scratch work' sections to expose the machinery of proofs about the natural numbers, relations, functions, and infinite sets. To give students the opportunity to construct their own proofs, this new edition contains over 200 new exercises, selected solutions, and an introduction to Proof Designer software. No background beyond standard high school mathematics is assumed. This book will be useful to anyone interested in logic and proofs: computer scientists, philosophers, linguists, and of course mathematicians.

Programming Legend Charles Petzold unlocks the secrets of the extraordinary and prescient 1936 paper by Alan M. Turing Mathematician Alan Turing invented an imaginary computer known as the Turing Machine; in an age before computers, he explored the concept of what it meant to be computable, creating the field of computability theory in the process, a foundation of present-day computer programming. The book expands Turing’s original 36-page paper with additional background chapters and extensive annotations; the author elaborates on and clarifies many of Turing’s statements, making the original difficult-to-read document accessible to present day programmers, computer science majors, math geeks, and others. Interwoven into the narrative are the highlights of Turing’s own life: his years at Cambridge and Princeton, his secret work in cryptanalysis during World War II, his involvement in seminal computer projects, his speculations about artificial intelligence, his arrest and prosecution for the crime of "gross indecency," and his early death by apparent suicide at the age of 41.

In 1931 the mathematical logician Kurt Godel published a revolutionary paper that challenged certain basic assumptions underpinning mathematics and logic. A colleague of Albert Einstein, his theorem proved that mathematics was partly based on propositions not provable within the mathematical system and had radical implications that have echoed throughout many fields. A gripping combination of science and accessibility, Godel’s Proofby Nagel and Newman is for both mathematicians and the idly curious, offering those with a taste for logic and philosophy the chance to satisfy their intellectual curiosity.

We first meet, Archangel Gabriel, with his personal accomplishments behind him, proclaimed the left hand and will of Yahweh, and with the love and respect of his fellow angels, he has become the most powerful angel in heaven. During his past five-thousand years of afterlife, he first believed that he had everything he could ever want, but something was missing, he needed and wanted more. Originally, a still-born, human soul, he never had a chance at life outside of heaven. But then something happened that made him desire what he had lost. It was Yahweh’s encouragement and plan for him to return to Earth and live as a human, however, returning would not be that simple. Becoming the first of his kind, Gabriel would retain his angel powers, but be without the memory of his past, thusly, forced to learn how to survive his dual nature, and obligated to recall his unknown previous life; he would require the help from one of his guardian-angel allies. But it will be Yahweh who orchestrates the situation by keeping Gabriel from knowing his fate and future destiny. Many adventures befall our hero, as he navigates through childhood, adolescence, adulthood, and the difficulties with romance. When Gabriel is forced to persevere over earthly and un-earthly villains, his lessons become more profound. With the help from his heavenly company, his fated time-line will take him through progressively greater challenges. Gabriel’s weapons will go beyond his charms and magical powers, which must include his knowledge, wisdom, and resolve. This illustrious legendary figure, is the nice guy who will finish first, ultimately finding personal fulfillment, and becoming more than he could ever imagine.

New Year's Eve, London, 1979... The sour taste in my mouth is all that is left of 1979. I had seen out the night, the year and the decade in a blaze of luminous cocktails that were still throbbing somewhere at the back of my skull. I'd spent the night in a fashionable London nightclub. Someone had fainted. At least, that's what I assumed. But now the phone rings. I answer it. A friend's voice screams at me: "He's dead! And they think I killed him!" It looked like it was going to be one of those days... The hunt is on for a murderer. There is no motive and far too many suspects. But there is one deadly clue - a bottle of mascara. Find the mascara and you find the murderer! This is not just fiction. It's how the '80s really were! Huw Collingbourne knows what he is writing about, because he was there. As a music journalist in the 1980s, he interviewed stars ranging from Boy George and Duran Duran to Spandau Ballet and Depeche Mode. He knows exactly what the '80s music and club scene was really like. He was in the music studio when Depeche Mode recorded 'Just Can't Get Enough', he went surfing with Haircut 100, he interviewed Motorhead's Lemmy over a breakfast of vodka and orange, he shared fashion tips with David Sylvian of Japan and he revealed to an astonished world that Robert Smith of The Cure dresses up as his mother when he cooks curries. Huw knows the people and the places. He went to Steve Strange's Blitz Club, rubbed shoulders with Spandau Ballet at The Camden Palace and had lunch with Adam Ant at a trendy restaurant in Primrose Hill. He interviewed stars ranging from The B52s and The Weather Girls to Judas Priest and Buster Bloodvessel. He wrote for the cult magazine, 'Flexipop!' as well as 'Number 1', 'Jackie', 'Kicks' and a range of other eighties pop music mags. He was responsible for writing a Flexipop! photo-story about cannibalism, featuring psychobilly band, The Meteors, which caused the magazine to be seized by the police and banned from sale. Never mind '80s-themed TV series such as Stranger Things and Ashes To Ashes, this book is the real deal. If you want to know what the fashion-pack world of 1980s Britain was really like, look no further. The 1980s Murder Mysteries series faithfully recreates that world, with a few murders along the way. If you enjoy murder mysteries with a dash of humour, Killers In Mascara is for you. 1980s London - the music, the nightclubs, the glitz, the glamour! Whoever would have thought murder could be so much fun! "This novel is completely original. The atmosphere generated gives a feeling of actually being there and involved in the scene. I would recommend this to anyone." Chris Bostock (of the '80s band, JoBoxers)
