Book Description
Each of a number of aluminum-alloy test specimens was loaded by random forces at a constant root-mean-square stress level until rupture occurred. The forces were statistically stationary and Gaussian with a zero mean value. The fatigue life (to rupture) was determined for various values of the following statistical parameters: (a) root-mean-square nominal applied stress, (b) power spectral shape, (c) mean number of zero crossings per unit time, and (d) mean number of peak loads per unit time. The power spectra were varied over a passband of frequency for three spectral shapes either by holding the power constant with frequency or by varying it either directly or inversely proportional to the square of the frequency. The results indicate that the fatigue life was determined principally by the root-mean-square nominal applied stress level. The effects of spectral shape, average number of zero crossings, and average number of peak loads were insignificant in the ranges investigated. The fatigue life, based on the number of effective cycles, of the specimens under random loading was lower by at least an order of magnitude at all stress levels than that of the specimens loaded sinusoidally. A linear cumulative damage theory overestimated the fatigue life, especially at low stress levels. The fracture characteristics of the specimens which failed under random loading were similar to those which failed under sinusoidal loads.

Book Description
In this fascinating book, mathematician Ed Beltrami takes a close enough look at randomness to make it mysteriously disappear. The results of coin tosses, it turns out, are determined from the start, and only our incomplete knowledge makes them look random. "Random" sequences of numbers are more elusive, but Godels undecidability theorem informs us that we will never know. Those familiar with quantum indeterminacy assert that order is an illusion, and that the world is fundamentally random. Yet randomness is also an illusion. Perhaps order and randomness, like waves and particles, are only two sides of the same (tossed) coin.

Book Description
In this thrilling and suspenseful fantasy set in the world of the New York Times bestselling Others series, an inn owner and her shape-shifting lodger find themselves enmeshed in danger and dark secrets. Human laws do not apply in the territory controlled by the Others--vampires, shape-shifters, and even deadlier paranormal beings. And this is a fact that humans should never, ever forget.... After her divorce, Vicki DeVine took over a rustic resort near Lake Silence, in a human town that is not human controlled. Towns such as Vicki's don't have any distance from the Others, the dominant predators who rule most of the land and all of the water throughout the world. And when a place has no boundaries, you never really know what is out there watching you. Vicki was hoping to find a new career and a new life. But when her lodger, Aggie Crowe--one of the shape-shifting Others--discovers a murdered man, Vicki finds trouble instead. The detectives want to pin the death on her, despite the evidence that nothing human could have killed the victim. As Vicki and her friends search for answers, ancient forces are roused by the disturbance in their domain. They have rules that must not be broken--and all the destructive powers of nature at their command.

Book Description
LONGLISTED FOR THE 2014 WINTON ROYAL SOCIETY PRIZE FOR SCIENCE BOOKS As troubling as we pattern-seeking humans may find it, modern science has repeatedly shown us that randomness is the underlying heartbeat of nature. In Dice World, acclaimed science writer Brian Clegg takes readers on an incredible trip around our random universe, uncovering the truths and lies behind probability and statistics, explaining how chaotic intervention is behind every great success in business, and demonstrating the possibilities quantum mechanics has given us for creating unbreakable ciphers and undergoing teleportation. He explores how the ‘clockwork universe’ imagined by Newton, in which everything could be predicted given enough data, was disproved bit by bit, to be supplanted by chaos theory and quantum physics. Clegg reveals a world in which not only is accurate forecasting often impossible but probability is the only way for us to understand the fundamental nature of things. Forget the clockwork universe. Welcome to Dice World, a unique portrait of a startlingly complex cosmos, from the bizarre microscopic world of the quantum to the unfathomable mechanics of planetary movements, where very little is as it seems...

Book Description
Fooled by Randomness is a standalone book in Nassim Nicholas Taleb’s landmark Incerto series, an investigation of opacity, luck, uncertainty, probability, human error, risk, and decision-making in a world we don’t understand. The other books in the series are The Black Swan, Antifragile, Skin in the Game, and The Bed of Procrustes. Fooled by Randomness is the word-of-mouth sensation that will change the way you think about business and the world. Nassim Nicholas Taleb–veteran trader, renowned risk expert, polymathic scholar, erudite raconteur, and New York Times bestselling author of The Black Swan–has written a modern classic that turns on its head what we believe about luck and skill. This book is about luck–or more precisely, about how we perceive and deal with luck in life and business. Set against the backdrop of the most conspicuous forum in which luck is mistaken for skill–the world of trading–Fooled by Randomness provides captivating insight into one of the least understood factors in all our lives. Writing in an entertaining narrative style, the author tackles major intellectual issues related to the underestimation of the influence of happenstance on our lives. The book is populated with an array of characters, some of whom have grasped, in their own way, the significance of chance: the baseball legend Yogi Berra; the philosopher of knowledge Karl Popper; the ancient world’s wisest man, Solon; the modern financier George Soros; and the Greek voyager Odysseus. We also meet the fictional Nero, who seems to understand the role of randomness in his professional life but falls victim to his own superstitious foolishness. However, the most recognizable character of all remains unnamed–the lucky fool who happens to be in the right place at the right time–he embodies the “survival of the least fit.” Such individuals attract devoted followers who believe in their guru’s insights and methods. But no one can replicate what is obtained by chance. Are we capable of distinguishing the fortunate charlatan from the genuine visionary? Must we always try to uncover nonexistent messages in random events? It may be impossible to guard ourselves against the vagaries of the goddess Fortuna, but after reading Fooled by Randomness we can be a little better prepared. Named by Fortune One of the Smartest Books of All Time A Financial Times Best Business Book of the Year
