The response of materials and the functioning of devices is often associated with noise. In this book, Stefano Zapperi concentrates on a particular type of noise, known as crackling noise, which is characterized by an intermittent series of broadly distributed pulses. While representing a nuisance in many practical applications, crackling noise can also tell us something useful about the microscopic processes ruling the materials behavior. Each crackle in the noise series usually corresponds to a localized impulsive event, an avalanche, occurring inside the material. A distinct statistical feature of crackling noise, and of the underlying avalanche behavior, is the presence of scaling, observed as power-law distributed noise pulses, long-range correlation, and scale free spectra. These are the hallmarks of critical phenomena and phase transitions. This work summarizes the current understanding of crackling noise, reviewing research undertaken in the past 30 years, from the early and influential ideas on self-organized criticality in sandpile models, to more modern studies on disordered systems. Crackling Noise covers the main theoretical models used to investigate avalanche phenomena, describes the statistical tools needed to analyze crackling noise, and provides a detailed discussion of a set of relevant examples of crackling noise in materials science. These include acoustic emission in fracture, strain bursts in amorphous and crystal plasticity, granular avalanches, magnetic noise in ferromagnets and superconductors, and fluid flow in porous media. The book concludes by considering the wider application of these models in the natural sciences.

“A great travel writer and more importantly a great traveler.” —Sydney Morning Herald When A. J. Mackinnon quits his job in Australia, he knows only that he longs to travel to the well at the world’s end, a mysterious pool on a remote Scottish island whose waters, legend has it, hold the secret to eternal youth. Determined not to fly—he claims it would feel as though he were cheating—he sets out with a backpack, some fireworks, and a map of the world and trusts that chance will take care of the rest. Traveling by land and sea, train, truck, horse, and yacht, Mackinnon travels across the world, getting caught up in a series of hilarious, sometimes surreal, adventures. He survives a near-fatal bus crash in Australia, accidentally marries a Laotian princess, is attacked by a Komodo dragon, and does time in a sketchy Chinese jail, among many other mishaps and misadventures along the way. Each new continent and each new mode of transport brings the possibility of a near-miss or happy accident, all on the quest for eternal youth. This is the astonishing true story of a remarkable voyage.
