Go, See, and Do: An Adventure
Par W. Davis Hawkins Jr.. 2019
A lifelong adventurer shares his fascinating story in this memoir of travel, life in Japan, and special assignments from the…
White House. Davis Hawkins lives a life of adventure and travel, approaching each opportunity with the mantra to &“Go, See, and Do.&” He chronicles his life through this lens, starting with his southern California upbringing before moving to Japan at an impressionable age. He experienced a changing America and East Asia landscape in the mid-twentieth century living abroad. These moments impacted his life through his military service and directed him to a successful financial and consulting careers overseas. Hawkins continued traveling, embracing any opportunity to visit different cultures. He visited more than eighty countries spanning all seven continents, finding human shrunken heads in Borneo, trekking in the Himalayas and the Amazon jungle, camping in the Gobi Desert, dining at the US State Department, couriering for the President of the United States, receiving a US congressional subpoena, surviving a military coup, and much more.Killer on the Road: Violence and the American Interstate (Discovering America #2)
Par Ginger Strand. 2012
Starting in the 1950s, Americans eagerly built the planet's largest public work: the 42,795-mile National System of Interstate and Defense…
Highways. Before the concrete was dry on the new roads, however, a specter began haunting them-the highway killer. He went by many names: the "Hitcher," the "Freeway Killer," the "Killer on the Road," the "I-5 Strangler," and the "Beltway Sniper. " Some of these criminals were imagined, but many were real. The nation's murder rate shot up as its expressways were built. America became more violent and more mobile at the same time. Killer on the Road tells the entwined stories of America's highways and its highway killers. There's the hot-rodding juvenile delinquent who led the National Guard on a multistate manhunt; the wannabe highway patrolman who murdered hitchhiking coeds; the record promoter who preyed on "ghetto kids" in a city reshaped by freeways; the nondescript married man who stalked the interstates seeking women with car trouble; and the trucker who delivered death with his cargo. Thudding away behind these grisly crime sprees is the story of the interstates-how they were sold, how they were built, how they reshaped the nation, and how we came to equate them with violence. Through the stories of highway killers, we see how the "killer on the road," like the train robber, the gangster, and the mobster, entered the cast of American outlaws, and how the freeway-conceived as a road to utopia-came to be feared as a highway to hell.How encounters with strongly electric fish informed our grasp of electricity.Spark from the Deep tells the story of how human beings…
came to understand and use electricity by studying the evolved mechanisms of strongly electric fish. These animals can shock potential prey or would-be predators with high-powered electrical discharges.William J. Turkel asks completely fresh questions about the evolutionary, environmental, and historical aspects of people’s interest in electric fish. Stimulated by painful encounters with electric catfish, torpedos, and electric eels, people learned to harness the power of electric shock for medical therapies and eventually developed technologies to store, transmit, and control electricity. Now we look to these fish as an inspiration for engineering new sensors, computer interfaces, autonomous undersea robots, and energy-efficient batteries.Praise for Spark from the Deep“This beautifully written and exhaustively researched book traces the links between experiments on strongly electric fish and scientific understanding of electricity . . . Turkel’s book is a joy to read; it will entertain and educate scientists, historians, and anyone with an interest in the natural world.” —Choice“Turkel’s book convincingly reminds us that all the laptops and gadgets we surround ourselves with are remixes; altered versions of strongly electric fish. For that strange and insightful observation, this book ought to be widely read and enjoyed.” —Chris Conway, Endeavour“[I]t is refreshing to explore a book which takes seriously ancient encounters with manifestations of natural electricity as precursors to more recent innovations.” —James F. Stark, The British Journal for the History of ScienceSeven Wonders of the Universe That You Probably Took for Granted
Par C. Rene James. 2011
A fascinating look at the scientific mysteries behind our everyday world—from night, light and gravity to our cosmic home and…
wonder itself.So much of what surrounds us feels familiar and mundane—until we look closer. C. Renée James opens the Universe to fantastical contemplation in this whimsical tour of seven everyday experiences: night, light, stuff, gravity, time, home, and wonder. James introduces each of these seven wonders with a simple question that appears to be easily answered. The questions are deceptive, though. Although we need light to see, there’s much more to it than meets the eye. When you get down to the atomic level, physical things are made of almost entirely empty space—99.9% nothing. And James’s contemplation of our place in the Universe shows that it’s not just a place to hang your hat—and that there’s really nothing else like it.James’s accessible discussion uses common analogies and entertaining illustrations to explain historical discoveries and concepts such as relativity, antimatter, and the electromagnetic spectrum. Fun and edifying, Seven Wonders of the Universe That You Probably Took for Granted is an inviting introduction to secret knowledge of our everyday world.Lawless Universe: Science and the Hunt for Reality
Par Joe Rosen. 2010
In this provocative reassessment of science, a physicist questions whether it can ever fully comprehend the entire material universe.There is…
no question that modern science has radically advanced our understanding of nature, the universe, and even reality itself. But in Lawless Universe, theoretical physicist Joe Rosen takes the scientific method down a peg. In his estimation, people like Stephen Hawking and Richard Dawkins are wrong to declare that science is on the verge of unlocking all the secrets of the universe. Perhaps without realizing it, they have crossed into the realm of metaphysics in an attempt to explain the unexplainable. Rosen considers the separate but entangled domains of science and metaphysics and examines the all-too-often ignored boundary between the objective and the subjective. He asserts that any understanding of the whole universe, if it is to be found at all, must come from nonscientific modes of comprehension and insight.Solar Magnetism

Par Edson Denis Leonel. 2023
This book discusses some scaling properties and characterizes two-phase transitions for chaotic dynamics in nonlinear systems described by mappings. The…
chaotic dynamics is determined by the unpredictability of the time evolution of two very close initial conditions in the phase space. It yields in an exponential divergence from each other as time passes. The chaotic diffusion is investigated, leading to a scaling invariance, a characteristic of a continuous phase transition. Two different types of transitions are considered in the book. One of them considers a transition from integrability to non-integrability observed in a two-dimensional, nonlinear, and area-preserving mapping, hence a conservative dynamics, in the variables action and angle. The other transition considers too the dynamics given by the use of nonlinear mappings and describes a suppression of the unlimited chaotic diffusion for a dissipative standard mapping and an equivalent transition in the suppression of Fermi acceleration in time-dependent billiards. This book allows the readers to understand some of the applicability of scaling theory to phase transitions and other critical dynamics commonly observed in nonlinear systems. That includes a transition from integrability to non-integrability and a transition from limited to unlimited diffusion, and that may also be applied to diffusion in energy, hence in Fermi acceleration. The latter is a hot topic investigated in billiard dynamics that led to many important publications in the last few years. It is a good reference book for senior- or graduate-level students or researchers in dynamical systems and control engineering, mathematics, physics, mechanical and electrical engineering.Fundamentals: Ten Keys to Reality

Par Levison Wood. 2020
From the award-winning explorer, “an entertaining summary of what we know about the elephant, and a call to change our…
behavior to ensure its survival” (Daily Mail).The Last Giants satisfies British explorer Levison Wood’s lifelong desire to learn more about the majestic African elephant. These giants trek through some of Africa’s most magnificent landscapes as they go in search of life-giving waters and pastures. El Nino’s droughts and an insatiable ivory trade have cut African elephant numbers by a third in the last decade alone, and if elephants disappear entirely, Africa’s entire ecosystem could collapse. But Botswana has become a safe haven, where one-sixth of the world’s elephants now reside. Each year their numbers grow and an incredible migration takes place, which Wood witnesses and records. He teams up with local trackers to gain insight into how this iconic species survives, camps out in the wild, meets the people and tribes living on the migration’s path, and joins the park rangers whose job it is to protect these land goliaths, equipped with his “good eye for detail and better ear for dialogue” (The Wall Street Journal).“Adventurer Wood followed elephants on a 650-mile migration across Botswana for a British television program. This fascinating companion volume to that series examines the past, present, and future of the African elephant.” —Library Journal (starred review)“A smart, inviting portrait of elephants from a keen-eyed observer.” —Kirkus Reviews“A rewarding look at the habits and habitats of the African elephant . . . Comprehensively yet accessibly conveying Wood’s lifelong fascination with African elephants, his discussion will appeal to anyone keen on learning more about them.” —Publishers WeeklyA Quantum Life (Adapted for Young Adults): My Unlikely Journey from the Street to the Stars
Par Joshua Horwitz, Hakeem Oluseyi. 2023
A NASA astrophysicist narrates his improbable journey from an impoverished childhood and an adolescence mired in drugs and crime to…
the nation's top physics PhD program at Stanford in this inspiring coming-of-age memoir.Born into extreme poverty and emotional deprivation, James Edward Plummer was blessed with a genius I.Q. and a love of science. But in his community, a young bookworm quickly becomes a target for violence and abuse. As he struggles to survive his childhood in some of the toughest cities in the country, and his teenage years in the equally poor backwoods of Mississippi, James adopts the hybrid persona of a "gangsta nerd"--dealing weed in juke joints while winning state science fairs with computer programs that untangle the mysteries of Einstein's relativity theory.When his prodigious intellect gains him admission to the elite Physics PhD program at Stanford University, James finds himself torn between his love of science and a dangerous crack cocaine habit he developed in college. With the encouragement of his mentor Art Walker, the lone Black faculty member in the physics department, James finally seizes his dream of a life in science and becomes his true adult self, changing his name to Hakeem Muata Oluseyi in honor--and celebration--of his African heritage. In the tradition of The Autobiography of Malcolm X and The Other Wes Moore, A Quantum Life is an uplifting journey to the stars fueled by hope, hustle, and a hungry mind. As he charts his development as a young scientist, Oluseyi also plumbs the mysteries of the universe where potential personal outcomes are as infinite as the stars in the sky.A Place in the World: Finding the Meaning of Home

Sun, in which the queen of wanderlust reflects on the comforts of home.&“A soulful meditation on &‘what home means, how it hooks the past and pushes into the future&’ . . . spellbinding.&”—Publishers Weekly (starred review) Though Frances Mayes is known for her travels, she has always sought a sense of home wherever she goes. In this poetic testament to the power of place in our lives, Mayes reflects on the idea of home, from the earliest imprint of four walls to the startling discoveries of feeling the strange ease of homes abroad, friends&’ homes, and even momentary homes that spark desires for other lives. Her musings are all the more poignant after so many have spent their long pandemic months at home. From her travels across Italy—Tuscany, of course, but also Venice and Capri—to the American South, France, and Mexico, Mayes examines the connective tissue among them through the homes she&’s inhabited. A Place in the World explores Mayes&’s passion and obsessions with houses and the things that inhabit them—old books, rich food, beloved friends, transportive art. The indelible marks each refuge has left on her and how each home influenced the next serve as the foundations of its chapters. Written in Mayes&’s signature intimate style, A Place in the World captures the adventure of moving on while seeking comfort in the cornerstone closest to all of us—home.To Hull and Back: On Holiday in Unsung Britain

Par Stephon Alexander. 2021
In this important guide to science and society, a cosmologist argues that physics must embrace the excluded, listen to the…
unheard, and be unafraid of being wrong. Years ago, cosmologist Stephon Alexander received life-changing advice: to discover real physics, he needed to stop memorizing and start taking risks. In Fear of a Black Universe, Alexander shows that great physics requires us to think outside the mainstream -- to improvise and rely on intuition. His approach leads him to three principles that shape all theories of the universe: the principle of invariance, the quantum principle, and the principle of emergence. Alexander uses them to explore some of physics' greatest mysteries, from what happened before the big bang to how the universe makes consciousness possible. Drawing on his experience as a Black physicist, he makes a powerful case for diversifying our scientific communities. Compelling and empowering, Fear of a Black Universe offers remarkable insight into the art of physics.Paradigms of Titanate Centered Energy Materials
Par Sanjay J. Dhoble, S. C. Sharma, Abhijeet R Kadam, G. P. Darshan, H. Nagabhushuna. 2024
Titanate-centered perovskites are an important class of crystalline materials with outstanding structural and property tunability. Recently, titanate perovskites have been…
extensively investigated as new-generation materials for various energy-allied applications, together with photovoltaic cells, light emitting diodes, photo detectors and lasers, for their exceptional optical and electronic properties. With increasing attention on the development of nanotechnology and multidisciplinary research, scientists have been trying to downscale the titanate perovskite structures into the nanoregime, so as to further boost their performances and applications. Compared with bulk perovskite materials, perovskite nanomaterials exhibit a series of advantages, such as fabrication of thin films and flexible devices and PNMs display high process ability. Perovskite nanomaterials feature rich and controllable facets and active sites. Besides benefiting from the small-size effect and quantum effect, perovskite nanomaterials are endowed with outstanding photo-electromagnetic properties. Furthermore, the applications of titanate-centered perovskites in the fields of energy, environment, WLEDs, forensic science and piezoelectric devices will be reviewed. This book will also discuss the possible solutions to the problems in their application by optimizing their compositions, structures and preparation methods. This book will systematically summarize the key points in the design, synthesis, property improvements and application expansion of titanate-centered perovskites. The different perovskite structures and the rational design of functional materials will be discussed in detail. The advantages, disadvantages and experimental parameters of different synthesis methods for titanate-centered perovskites will be reviewed. This book will also summarize some practical experiences in selecting suitable elements and designing multifunctional materials according to the mechanisms and principles of elements promoting the properties of perovskites by covering almost last 20 years of literature. At the end of this book, we will provide an outlook on the opportunities and challenges in the view of development in titanate-centered perovskites The inclusive effectiveness and practicality of prospective titanate energy materials and systems are directly connected to many materials-related factors. This volume of book features totally seven sections that envelop a wide range of titanate energy materials. They cover the modern developments involving materials for alternative and renewable energy sources and systems, including energy storage and batteries, nanocomposites, hydrogen, solar, wind, geothermal, biomass and nuclear. The book is a significant orientation for students and researchers (from academics, but also industry) interested in understanding the properties of emerging titanate energy materials and challenges in the recent era.Theory of Liquids: From Excitations to Thermodynamics
Par Kostya Trachenko. 2023
Of the three basic states of matter, liquid is perhaps the most complex. While its flow properties are described by…
fluid mechanics, its thermodynamic properties are often neglected, and for many years it was widely believed that a general theory of liquid thermodynamics was unattainable. In recent decades that view has been challenged, as new advances have finally enabled us to understand and describe the thermodynamic properties of liquids. This book explains the recent developments in theory, experiment and modelling that have enabled us to understand the behaviour of excitations in liquids and the impact of this behaviour on heat capacity and other basic properties. Presented in plain language with a focus on real liquids and their experimental properties, this book is a useful reference text for researchers and graduate students in condensed matter physics and chemistry as well as for advanced courses covering the theory of liquids.Culinary Tourism (Material Worlds)

Culinary Tourism is the first book to consider food as both a destination and a means for tourism. The book's…
contributors examine the many intersections of food, culture and tourism in public and commercial contexts, in private and domestic settings, and around the world. The contributors argue that the sensory experience of eating provides people with a unique means of communication. Editor Lucy explains how and why interest in foreign food is expanding tastes and leading to commercial profit in America, but the book also show how tourism combines personal experiences with cultural and social attitudes toward food and the circumstances for adventurous eating.
