The last climb of George Mallory and Andrew Irvine, towards the summit of Mount Everest on 8 June 1924, has been shrouded in mystery for a century. Were they the first humans to stand at the highest point in the world? The discovery of Mallory's body in 1999 did nothing to resolve the mystery. Until now, accounts of their climb have been driven by speculation and preconceived narrative.In this book, which marks the 100th anniversary of the fateful climb, Dr Robert Edwards brings the fresh and original perspective of a mathematician to the story of Mallory and Irvine.Dr Edwards has assembled the contemporary accounts of the early British expeditions, written by the climbers and their leaders, and has identified their anomalies and inconsistencies. He has studied the letters of George Mallory, and has held in his hand the diaries of Andrew Irvine. He has viewed, in person, some of the surviving artifacts: the ice axe found in 1933, and Mallory's boots, recovered in 1999\. He has corresponded with modern mountaineers who have climbed Everest. Above all, he has applied mathematics and modern imaging and mapping technology to an analysis of what the 1924 climbers could, and could not, have seen and done.

The only unsolved act of air piracy in US history from the perspective of a mathematician and pilot. On November 24, 1971, a polite, nondescript, and dark-complexioned man calling himself "Dan Cooper" hijacked Northwest Airlines Flight 305, Boeing 727, between Portland, Oregon, and Seattle, Washington. At Seattle International Airport, he demanded and received $200,000 and four parachutes, released the passengers, and ordered the crew to take him to Mexico. Somewhere along the way, he jumped. He was never found or identified. Forty-five years later, the FBI gave up the hunt. To show where and how the FBO could resume the search and possibly find out at last who “D. B. Cooper” really was, this book utilizes: Previously unexamined data and original-source documentsUsing statistics, aeronautics, and meteorologyAuthor Bob Edwards is an economist and a contractor in economic, demographic, and market research. He holds a private pilot's license and has experience in parachuting, giving him a unique perspective in the possibilities of the D. B. Cooper case.

Dr. Robert Edwards, MSc, PhD, brings a fresh, mathematical perspective to the Voynich manuscript and sets out a strategy whereby the interested reader could extract meaning from the seemingly impenetrable symbols... if meaning is there to be found. The Voynich manuscript has been described as the most mysterious document in the world. In 1637, a Bohemian scholar sent a mysterious manuscript to the celebrated professor Athanasius Kircher in Rome. Kircher promised to decipher it when the mood took him. He never did. Later, antiquarian bookseller Wilfrid Voynich claimed that he had discovered it in 1912 in a castle in Europe. It contains hundreds of bizarre illustrations that seem to represent plants, stars, animals, zodiac signs, strange receptacles, and naked women in pools and streams of green water. Throughout its over 200 pages are strings of glyphs or symbols that look like words, but the symbols do not belong to any known living or extinct languages. No one knows what these symbols mean—or even whether they mean anything, though hundreds of scholars have tried to decipher them for 500 years. Today, all that we know for sure is that the parchment probably dates from the early 15th century. Voynich Reconsidered presents a detailed look at a 500-year-old mystery guide through the lens of the author's own systematic analysis of the manuscript's undeciphered glyphs and illustrations, all in an effort to aid readers in finding the manuscript's possible true meaning. This a book for anyone fascinated by ancient languages and mysterious codes.
