As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from this plus this equals this to this plus what equals this? gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

    Dr. Euler's Fabulous Formula shares the fascinating story of this groundbreaking formula--long regarded as the gold standard for mathematical beauty--and shows why it still lies at the heart of complex number theory. This book is the sequel to Paul Nahin's An Imaginary Tale: The Story of I [the square root of -1], which chronicled the events leading up to the discovery of one of mathematics' most elusive numbers, the square root of minus one. Unlike the earlier book, which devoted a significant amount of space to the historical development of complex numbers, Dr. Euler begins with discussions of many sophisticated applications of complex numbers in pure and applied mathematics, and to electronic technology. The topics covered span a huge range, from a never-before-told tale of an encounter between the famous mathematician G. H. Hardy and the physicist Arthur Schuster, to a discussion of the theoretical basis for single-sideband AM radio, to the design of chase-and-escape problems. The book is accessible to any reader with the equivalent of the first two years of college mathematics (calculus and differential equations), and it promises to inspire new applications for years to come. Or as Nahin writes in the book's preface: To mathematicians ten thousand years hence, Euler's formula will still be beautiful and stunning and untarnished by time.

     The Crash Of MH370 may well be one those ground breaking accidents that change our way of thinking. This book is an analysis of the mystery that is the missing Malaysian Airlines 777, and one of the first to be published after the search concluded. Unlike previous books about the ghost plane written by well-meaning amateur pilots and journalists, the author is an industry insider; an A380 captain with similar experience to the missing pilot. It examines the facts, who’s who, the flight and search. The latter half dispels the various theories, provides the author’s best guess as to what happened and delivers a list of thirteen urgent recommendations for the industry. Rarely do we hear from people within this industry. From pilots and air traffic controllers to crash investigators, their employment contracts stipulate: no media. That James Nixon has chosen to publish this book within three months of his retirement means we are given a rare chance to peek behind the cockpit door.

    Names of Kings and major political/military persons have been updated and major typographical errors found with the previous Kindle edition have been corrected. Combined with copious illustrations, maps and images, the newly revised Dark Ages is essential reading for anyone seeking to understand a critical period in Western history that saw the transition from Roman Imperial rule to conquest-driven tribal rule and, ultimately, a flowering into the High Middle Ages. Oman provides one of the best historical examinations and explanations about the period widely known as the Dark Ages, when the end of total and complex Roman Imperial rule over Europe and the Mediterranean collapsed, taking the institutions that provided so much cultural sophistication and stability with it. The Dark Ages has been split into three books, mainly for ease of reading; the original book published in 1893 was a massive tome that covered the period from 476 CE to 918 CE. This second book in the new edition covers the period from 561 CE to 743 CE:THE SUCCESSORS OF JUSTINIAN 565-610DECLINE AND DECAY OF THE MEROVINGIANS 561-656THE LOMBARDS IN ITALY, AND THE RISE OF THE PAPACY 568-653HERACLIUS AND MOHAMMED 610-641THE DECLINE AND FALL OF THE VISIGOTHS A.D. 603-711THE CONTEST OF THE EASTERN EMPIRE AND THE CALIPHATE 641-717THE HISTORY OF THE GREAT MAYORS OF THE PALACE 656-720THE LOMBARDS AND THE PAPACY 653-743CHARLES MARTEL AND HIS WARS 720-741
