Even when dealing with standard material, Stillwell manages to dramatize it and to make it worth rethinking. In short, his book is a splendid addition to the genre of works that build royal roads to mathematical culture for the many." (Mathematical Intelligencer)This second edition includes new chapters on Chinese and Indian number theory, on hypercomplex numbers, and on algebraic number theory. Many more exercises have been added, as well as commentary to the exercises explaining how they relate to the preceding section, and how they foreshadow later topics.

    Abstract ideas, for the most part, arise via conceptual metaphor-metaphorical ideas projecting from the way we function in the everyday physical world. Where Mathematics Comes From argues that conceptual metaphor plays a central role in mathematical ideas within the cognitive unconscious-from arithmetic and algebra to sets and logic to infinity in all of its forms.

    Offering inspiration and intellectual delight, the problems throughout the book encourage students to express their ideas in writing to explain how they conceive problems, what conjectures they make, and what conclusions they reach. Applying specific techniques and strategies, readers will acquire a solid understanding of the fundamental concepts and ideas of number theory.

    You proceed at your own rate and any difficulties you may encounter are resolved before you move on to the next topic. With a step-by-step programmed approach that is complemented by hundreds of worked examples and exercises, Advanced Engineering Mathematics is ideal as an on-the-job reference for professionals or as a self-study guide for students.Uses a unique technique-oriented approach that takes the reader through each topic step-by-step.Features a wealth of worked examples and progressively more challenging exercises.Contains Test Exercises, Learning Outcomes, Further Problems, and Can You? Checklists to guide and enhance learning and comprehension.Expanded coverage includes new chapters on Z Transforms, Fourier Transforms, Numerical Solutions of Partial Differential Equations, and more Complex Numbers.Includes a new chapter, Introduction to Invariant Linear Systems, and new material on difference equations integrated into the Z transforms chapter.

    In Code Breaking , Rudolf Kippenhahn offers readers both an exciting chronicle of cryptography and a lively exploration of the cryptographer’s craft. Rich with vivid anecdotes from a history of coding and decoding and featuring three new chapters, this revised and expanded edition makes the often abstruse art of deciphering coded messages accessible to the general reader and reveals the relevance of codes to our everyday high-tech society. A stylishly written, meticulously researched adventure, Code Breaking explores the ways in which communication can be obscured and, like magic, made clear again.

    

     Free BONUS Inside! As the sole legitimate child of Lord Byron, Ada Lovelace was the progeny of literary royalty. Many might have naturally expected her to go into the field of her father, but instead of delving into poetry, she delved into the hard sciences of mathematics and analytic thinking. Even so, Ada still had the imagination of a lyricist when writing scientific treatises, at times referring to her own work as nothing short of “poetical science.” Everything she did, she did with passion and dogged determination. It was this drive that led Ada to look farther and search deeper than her contemporaries. Her unique vision led her to become one of the pioneers of the modern computer and one of the world’s first computer programmers. But what exactly do we know about Ada Lovelace, and how can it be quantified? Read this book to find out more about the nineteenth-century mathematician and writer Augusta Ada King, Countess of Lovelace. Discover a plethora of topics such as The Daughter of Lord and Lady Byron Early Years of Paralysis The World’s First Computer Programmer Rumors and Laudanum Addiction A Grim Prognosis Last Days and Death And much more!

    Set amid the civil rights movement, the never-before-told true story of NASA’s African-American female mathematicians who played a crucial role in America’s space program. Before Neil Armstrong walked on the moon, a group of professionals worked as ‘Human Computers’, calculating the flight paths that would enable these historic achievements. Among these were a coterie of bright, talented African-American women. Segregated from their white counterparts, these ‘coloured computers’ used pencil and paper to write the equations that would launch rockets and astronauts, into space. Moving from World War II through NASA’s golden age, touching on the civil rights era, the Space Race, the Cold War and the women’s rights movement, ‘Hidden Figures’ interweaves a rich history of mankind’s greatest adventure with the intimate stories of five courageous women whose work forever changed the world.

    Only 17 when he enlisted in 1964, Johnson deployed to Vietnam with the 3rd Reconnaissance Battalion, 3rd Marine Division, and his tour included such now famous locations as Phu Bai, Khe Sanh, Nha Trang and Quang Tri, among others. With a sometimes humorous tone, Johnson describes a war of often terrified high school and college-aged youngsters faced with exotic plant and animal life, monsoon rains, harrowing reconnaissance missions and death. Details are plentiful about tactics, equipment, geography and, always, fellow Marines.

    

    

    He was 47 years old. During his time on the ground he kept a diary. Humorous, authentic and sad, it is a warts and all account of infantry soldiering in a hot and dangerous place. This is his storty.

    They operated out of Chu Lai the sprawling base camp on the coast of South Vietnam, home to the 23rd Infantry Division and the 75th Rangers. Their missions were conducted in the northern provinces, dubbed by the military as 1st Combat Tactical Zone (1CTZ).From Rosemary's Point at Chu Lai, to Da Nang, to the Tuy Lon River and the White Mountains, across the Hai Van Pass to Phu Bai. They were both recon and striker unit, sometimes just looking for intell, sometimes attacking and sometimes being attacked. Often deployed to reinforce a small camp or firebase. Sometimes workng as convoy security.Mostly it was HOT! Life for them was either base camp boring, or "boonie rat" intense in full "battle rattle". Sometimes assigned missions to locate or capture specific targets. All of their missions were both classified and clandestine. Even their existence was denied. As much as possible their movements were hidden or camouflaged within larger unit operations and movements. Their operations were usually conducted with niether back-up, nor support readily available. They were required to move and survive on their bush skills, to adapt, over come, improvise, or if that failed E&E (escape and evade) back to a pick-up or rendezvous point for extraction. This story is about serving in Vietnam as professional soldiers in a "No Such Unit Exists" status. Part of the "other" Army in - South Vietnam, Republic of "A HARD PLACE."
