From the author of How the Universe Got Its Spots and A Madman Dreams of Turing Machines, the epic story of the scientific campaign to record the soundtrack of our universe.
Black holes are dark. That is their essence. When black holes collide, they will do so unilluminated. Yet the black hole collision is an event more powerful than any since the origin of the universe. The profusion of energy will emanate as waves in the shape of spacetime: gravitational waves. No telescope will ever record the event; instead, the only evidence would be the sound of spacetime ringing. In 1916, Einstein predicted the existence of gravitational waves, his top priority after he proposed his theory of curved spacetime. One century later, we are recording the first sounds from space, the soundtrack to accompany astronomy’s silent movie.
In Black Hole Blues and Other Songs from Outer Space, Janna Levin recounts the fascinating story of the obsessions, the aspirations, and the trials of the scientists who embarked on an arduous, fifty-year endeavor to capture these elusive waves. An experimental ambition that began as an amusing thought experiment, a mad idea, became the object of fixation for the original architects—Rai Weiss, Kip Thorne, and Ron Drever. Striving to make the ambition a reality, the original three gradually accumulated an international team of hundreds. As this book was written, two massive instruments of remarkably delicate sensitivity were brought to advanced capability. As the book draws to a close, five decades after the experimental ambition began, the team races to intercept a wisp of a sound with two colossal machines, hoping to succeed in time for the centenary of Einstein’s most radical idea. Janna Levin’s absorbing account of the surprises, disappointments, achievements, and risks in this unfolding story offers a portrait of modern science that is unlike anything we’ve seen before.
From the Hardcover edition.
A unified account of the field rather than a description of parallel methods, the text's main thematic approaches include the self-consistent field and its generalizations, perturbation theory and the use of Feynman diagrams, and the use of Green functions to describe excitations of a many-body system. The primary emphasis is on the theories of atomic nuclei, the electron gas, superconductivity, and liquid helium three. A familiarity with the principles of nonrelativistic quantum mechanics and statistical mechanics is assumed, but a detailed knowledge of nuclear and solid state physics is unnecessary.
For centuries, mariners have spun tales of gargantuan waves, 100-feet high or taller. Until recently scientists dismissed these stories—waves that high would seem to violate the laws of physics. But in the past few decades, as a startling number of ships vanished and new evidence has emerged, oceanographers realized something scary was brewing in the planet’s waters. They found their proof in February 2000, when a British research vessel was trapped in a vortex of impossibly mammoth waves in the North Sea—including several that approached 100 feet.
As scientists scramble to understand this phenomenon, others view the giant waves as the ultimate challenge. These are extreme surfers who fly around the world trying to ride the ocean’s most destructive monsters. The pioneer of extreme surfing is the legendary Laird Hamilton, who, with a group of friends in Hawaii, figured out how to board suicidally large waves of 70 and 80 feet. Casey follows this unique tribe of people as they seek to conquer the holy grail of their sport, a 100-foot wave.
In this mesmerizing account, the exploits of Hamilton and his fellow surfers are juxtaposed against scientists’ urgent efforts to understand the destructive powers of waves—from the tsunami that wiped out 250,000 people in the Pacific in 2004 to the 1,740-foot-wave that recently leveled part of the Alaskan coast.
Like Jon Krakauer’s Into Thin Air, The Wave brilliantly portrays human beings confronting nature at its most ferocious.
This is an ideal reference for professionals in the public and private power service sectors such as engineers, lawyers, systems specialists, economists, financial analysts, policy analysts, and applied mathematicians.
Serving both as a text for students in engineering departments and as a reference for practicing engineers, this book focuses on electroacoustics, analyzing the behavior of transducers with the aid of electro-mechano-acoustical circuits. Assuming knowledge of electrical circuit theory, it starts by guiding readers through the basics of sound fields, the laws governing sound generation, radiation, and propagation, and general terminology. It then moves on to examine:Microphones (electrostatic and electromagnetic), electrodynamic loudspeakers, earphones, and hornsLoudspeaker enclosures, baffles, and waveguidesMiniature applications (e.g., MEMS in I-Pods and cellphones)Sound in enclosures of all sizes, such as school rooms, offices, auditoriums, and living rooms
Numerical examples and summary charts are given throughout the text to make the material easily applicable to practical design. It is a valuable resource for experimenters, acoustical consultants, and to those who anticipate being engineering designers of audio equipment.An update for the digital age of Leo Beranek's classic 1954 book AcousticsProvides detailed acoustic fundamentals, enabling better understanding of complex design parameters, measurement methods, and dataExtensive appendices cover frequency-response shapes for loudspeakers, mathematical formulas, and conversion factors
Addressing questions most ocean visitors have had and offering new ones for our consideration, The Science of Ocean Waves explains in accessible language how waves are formed, how they move, how they become huge and destructive, and how they're being studied now for clues that will help us plan for the future.
Devoting chapters to wind, tides, currents, breakers, tsunamis, forecasting, renewable energy, and El Niño—as well as discussing the gentler properties of ocean waves which inspire us and offer opportunities for relaxation and recreation—Zirker explores the physical factors that create waves.
Drawing on some of the recent storms that have devastated entire regions—such as Hurricane Katrina, the tsunami launched by the 2004 Sumatran earthquake, and the great tsunami that crushed the shore of Japan in 2011—Zirker explains the forces that cause these monster waves and reveals the toll they take on human lives.
Enhanced by dozens of illustrations and a comprehensive glossary, The Science of Ocean Waves will fascinate anyone curious about the science behind the headlines.
Praise for J. B. Zirker
"Scientists know their stuff but are rarely good storytellers, whereas good storytellers rarely possess the necessary sweeping command of a scientific discipline. Zirker is that rare animal who can both communicate the most demanding technical detail and make it accessible."— New Scientist-- Chris Almond

In this simple, descriptive treatment of Tesla's work:
- We start with the analysis of Tesla's experiment in his US patent 787412, providing explanations for his lower bounds, requirements, and superluminal speeds. Modes of operation of Tesla transformer are analyzed, and the true nature of the so-called Tesla-wave explained, considering what renders it to be the most significant technological discovery to date.
- We recognize that the very discovery of radio is a witness to the physical existence of invisible, exclusively 3-dimensional worlds, and spherical potential waves in a fully three-dimensional imaginary space are a fundamental phenomenon and physical reality.
- We progress to discuss implications and applications, and claim that properly constructed radio waves do not travel through our visible domain, allowing for efficient wireless energy transfer irrespective of distance.
- Finally, concentrated in one of the last of the 12 chapters, we present a concise mathematical treatment based on Maxwell's equations in characterizing the Tesla effect.
Redefining the thinking outside-the-box and challenging the state of the art in modern physics, I submit this innovation to your careful scrutiny. This descriptive work is accessible to any reader, including physics and mathematics scholars skilled in the art. The combined experience in the above treatment yields a novel, simple, yet comprehensive view of the spatial construction of the universe, above and beyond the everyday three-dimensional reality experienced by physical senses.
No sensationalist descriptions involving time travel, weapons of global destruction, Soviet military research, mind alteration, age reversal, UFOs, aliens, and a myriad of other manufactured and unrelated topics, are contained in this text. No strings, tensors, elementary particles, or any of the traditional special relativity effects are associated with Tesla waves, and are not mentioned in this text. The most significant problem in theoretical interpretation of Tesla's ideas to date - was the avoidance of the most obvious solution.
Read this flagship book, and discover that the universe is so small that we are all intimately connected through a countably infinite set of pathways of ever decreasing length, and that it is yet so large, that it escapes our senses.
Universe is a lattice of countably infinitely many, mutually embedded, distinct, experientially equivalent, fully-fledged three-dimensional worlds, with all corresponding lengths ratio of Pi/2. Illustrated in C^3 , universe is simply a sphere of radius zero.

Dr Michael Ainslie is eminently qualified to write this unique book. He has worked on sonar performance modeling problems since 1983. He has written many peer reviewed research articles and conference papers related to sonar performance modeling, making contributions in the fields of sound propagation and detection theory.
Peter Markos and Costas Soukoulis begin by establishing the analogy between wave propagation in electronic systems and electromagnetic media and then show how the transfer matrix can be easily applied to any type of wave propagation, such as electromagnetic, acoustic, and elastic waves. The transfer matrix approach of the tight-binding model allows readers to understand its implementation quickly and all the concepts of solid-state physics are clearly introduced. Markos and Soukoulis then build the discussion of such topics as random systems and localized and delocalized modes around the transfer matrix, bringing remarkable clarity to the subject. Total internal reflection, Brewster angles, evanescent waves, surface waves, and resonant tunneling in left-handed materials are introduced and treated in detail, as are important new developments like photonic crystals, negative index materials, and surface plasmons. Problem sets aid students working through the subject for the first time.

That is why this valuable reference provides a complete survey of methods for computational acoustics, namely FEM and BEM. It demonstrates that both methods can be effectively used in the complementary cases.
The chapters by well-known authors are evenly balanced: 10 chapters on FEM and 10 on BEM. An initial conceptual chapter describes the derivation of the wave equation and supplies a unified approach to FEM and BEM for the harmonic case. A categorization of the remaining chapters and a personal outlook complete this introduction. In what follows, both FEM and BEM are discussed in the context of very different problems.
Firstly, this comprises numerical issues, e.g. convergence, multi-frequency solutions and highly efficient methods; and secondly, solutions techniques for the particular difficulties that arise with external problems, e.g. discussion of absorbing boundaries for FEM and treatment of the non-uniqueness problem for BEM. Finally, both parts on FEM and on BEM are completed by chapters on related problems, e.g. formulations for fluid-structure interaction. In addition to time-harmonic problems, transient problems are considered in some chapters. Many theoretical and industrial applications are presented.
Overall, this book is a unified review of the state-of-the-art on FEM and BEM for computational acoustics.

This simple inversion reveals a panoply of possibilities by which we can re-evaluate how hearing animals use, produce, and perceive sound. Nuance in vocalizations become signals of enticement or boundary setting; silence becomes a field ripe in auditory possibilities; predator/prey relationships are infused with acoustic deception, and sounds that have been considered territorial cues become the fabric of cooperative acoustical communities. This inversion also expands the context of sound perception into a larger perspective that centers on biological adaptation within acoustic habitats. Here, the rapid synchronized flight patterns of flocking birds and the tight maneuvering of schooling fish becomes an acoustic engagement. Likewise, when stridulating crickets synchronize their summer evening chirrups, it has more to do with the ‘cricket community’ monitoring their collective boundaries rather than individual crickets establishing ‘personal’ territory or breeding fitness.
In "Hear Where We Are" the author continuously challenges many of the bio-acoustic orthodoxies, reframing the entire inquiry into sound perception and communication. By moving beyond our common assumptions, many of the mysteries of acoustical behavior become revealed, exposing a fresh and fertile panorama of acoustical experience and adaptation.
The book discusses in detail the derivation of general sparse representations of acoustic MIMO systems in signal or system dependent transform domains. Efficient adaptive filtering algorithms in the transform domains are presented and the relation between the signal- and the system-based sparse representations is emphasized. Furthermore, the book presents a novel approach to spatially preprocess the loudspeaker signals in a full-duplex communication system. The idea of the preprocessing is to prevent the echoes from being captured by the microphone array in order to support the AEC system. The preprocessing stage is given as an exemplarily application of a novel unified framework for the synthesis of sound figures. Finally, a multichannel system for the acoustic echo suppression is presented that can be used as a postprocessing stage for removing residual echoes. As first of its kind, it extracts the near-end signal from the microphone signal with a distortionless constraint and without requiring a double-talk detector.
The first edition of this unique interdisciplinary guide has become the foundational systems engineering textbook for colleges and universities worldwide. It has helped countless readers learn to think like systems engineers, giving them the knowledge, skills, and leadership qualities they need to be successful professionals.
