The monograph is devoted to the issues of scientific substantiation of ways to improve the efficiency of the functioning of the executive bodies of coal mining machines used in the underground mining of coal seams, which are of great practical importance. The results of studies on the reliability of destructive organs are new in the formulation and not previously published in the monograph format. A model is described and a physical interpretation of the failure patterns of auger assemblies and elements is given, methods for assessing the reliability and efficiency of using augers and cutting tools for specific operating conditions using traditional probabilistic and new energy approaches are proposed. It is addressed to engineering and technical workers of design institutions, factories and mines engaged in the design and operation of cleaning combines and plows.

The monograph discusses the application of nonparametric criteria of agreement (Kolmogorov, Cooper, Kramer-Mises -Smirnov, Watson, Anderson -Darling, Zhang) when testing simple and complex hypotheses. The appendix contains tables containing percentage points and statistical distribution models necessary for the correct use of criteria when testing simple and, most importantly, various complex hypotheses. In comparison with the first edition, more attention is paid to the application of criteria in non-standard application conditions, in particular for the analysis of large samples. It is shown that in applications, the properties of criteria can change significantly due to the presence of rounding errors, and this must be taken into account when forming statistical conclusions. Following the recommendations in data analysis will ensure the correctness of statistical conclusions and increase their validity. It is designed for specialists who, in one way or another, face issues of statistical data analysis, processing of experimental results, the use of statistical methods to analyze various aspects and trends of the surrounding reality in their activities. It will be useful for engineers, researchers, specialists of various profiles (physicians, biologists, sociologists, economists, etc.), university teachers, graduate students and students.

Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability. Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves. This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, monitoring, surface water control and closure of weak rock slopes. As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.

Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on rock slope stability in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners. This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting rock slope stability and reliability in open pit mines. It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring. Guidelines for Open Pit Slope Design comprises 14 chapters that directly follow the life of mine sequence from project commencement through to closure. It includes: information on gathering all of the field data that is required to create a 3D model of the geotechnical conditions at a mine site; how data is collated and used to design the walls of the open pit; how the design is implemented; up-to-date procedures for wall control and performance assessment, including limits blasting, scaling, slope support and slope monitoring; and how formal risk management procedures can be applied to each stage of the process. This book will assist in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

The world's largest demonstrator of a revolutionary energy system in desalination for drinking water production is in operation. MIDES uses Microbial Desalination Cells (MDC) in a pre-treatment step for reverse osmosis (RO), for simultaneous saline stream desalination and wastewater treatment. MDCs are based on bio-electro-chemical technology, in which biological wastewater treatment can be coupled to the desalination of a saline stream using ion exchange membranes without external energy input. MDCs simultaneously treat wastewater and perform desalination using the energy contained in the wastewater. In fact, an MDC can produce around 1.8 kWh of bioelectricity from the energy contained in 1 m3 of wastewater. Compared to traditional RO, more than 3 kWh/m3 of electrical energy is saved. With this novel technology, two low-quality water streams (saline stream, wastewater) are transformed into two high-quality streams (desalinated water, treated wastewater) suitable for further uses. An exhaustive scaling-up process was carried out in which all MIDES partners worked together on nanostructured electrodes, antifouling membranes, electrochemical reactor design and optimization, life cycle assessment, microbial electrochemistry and physiology expertise, and process engineering and control. The roadmap of the lab-MDC upscaling goes through the assembly of a pre-pilot MDC, towards the development of the demonstrator of the MDC technology (patented). Nominal desalination rate between 4-11 Lm-2h-1 is reached with a current efficiency of 40 %. After the scalability success, two MDC pilot plants were designed and constructed consisting of one stack of 15 MDC pilot units with a 0.4 m2 electrode area per unit. This book presents the information generated throughout the EU funded MIDES project and includes the latest developments related to desalination of sea water and brackish water by applying microbial desalination cells.

Guidelines for Evaluating Water in Pit Slope Stability is a comprehensive account of the hydrogeological procedures that should be followed when performing open pit slope stability design studies. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit mines, this book expands on the hydrogeological model chapter in the LOP project's previous book Guidelines for Open Pit Slope Design (Read & Stacey, 2009; CSIRO PUBLISHING). The book comprises six sections which outline the latest technology and best practice procedures for hydrogeological investigations. The sections cover: the framework used to assess the effect of water in slope stability; how water pressures are measured and tested in the field; how a conceptual hydrogeological model is prepared; how water pressures are modelled numerically; how slope depressurisation systems are implemented; and how the performance of a slope depressurisation program is monitored and reconciled with the design. Guidelines for Evaluating Water in Pit Slope Stability offers slope design practitioners a road map that will help them decide how to investigate and treat water pressures in pit slopes. It provides guidance and essential information for mining and civil engineers, geotechnical engineers, engineering geologists and hydrogeologists involved in the investigation, design and construction of stable rock slopes.

This chapter focuses on players other than Host States and mining companies in the mining industry. These include prospectors, geologists, mining engineers, metallurgical engineers, trading houses, smelters, assayers, and investment banks. Prospectors play an important role in generating showings (evidence of localized mineralization), which are later optioned, acquired, or explored by mining companies. Geologists specialize in exploring and identifying new mines. Mining engineers specialize in mine design while metallurgical engineers devise and design the processes and physical installations necessary to process raw ore into refined metals or minerals. Most mining companies do not market or sell their production, relying instead on trading houses to buy their output, or selling it to large industrial users under long-term supply and purchase agreements. Smelters process the ore mined into refined metals. Assayers perform the chemical and metallurgical tests on samples of ores or minerals to determine the amount of valuable metals contained. Investment banks arrange the financing for mining projects. These different actors and activities entail specific risks and varying potential for international disputes.

Guidelines for Mine Waste Dump and Stockpile Design is a comprehensive, practical guide to the investigation, design, operation and monitoring of mine waste dumps, dragline spoils and major stockpiles associated with large open pit mines. These facilities are some of the largest man-made structures on Earth, and while most have performed very well, there are cases where instabilities have occurred with severe consequences, including loss of life and extensive environmental and economic damage. Developed and written by industry experts with extensive knowledge and experience, this book is an initiative of the Large Open Pit (LOP) Project. It comprises 16 chapters that follow the life cycle of a mine waste dump, dragline spoil or stockpile from site selection to closure and reclamation. It describes the investigation and design process, introduces a comprehensive stability rating and hazard classification system, provides guidance on acceptability criteria, and sets out the key elements of stability and runout analysis. Chapters on site and material characterisation, surface water and groundwater characterisation and management, risk assessment, operations and monitoring, management of ARD, emerging technologies and closure are included. A chapter is also dedicated to the analysis and design of dragline spoils. Guidelines for Mine Waste Dump and Stockpile Design summarises the current state of practice and provides insight and guidance to mine operators, geotechnical engineers, mining engineers, hydrogeologists, geologists and other individuals that are responsible at the mine site level for ensuring the stability and performance of these structures. Readership includes mining engineers, geotechnical engineers, civil engineers, engineering geologists, hydrogeologists, environmental scientists, and other professionals involved in the site selection, investigation, design, permitting, construction, operation, monitoring, closure and reclamation of mine waste dumps and stockpiles.

This chapter details the selection of Octave Chanute to design and build a lasting bridge across the unbridged Missouri River at Kansas City. The offer to bridge the Missouri, the most difficult of all navigable streams, was a compliment for Chanute, but also a formidable challenge to his ambition as a civil engineer. The completion of the bridge called for the construction of about four hundred miles of connecting roads, bringing urbanization to the Kansas frontier. The thirty-seven-year-old Chanute built this rail system and connected it with eastern railroads, bringing profit to both systems. During the first 230 days of operation, 5,263 locomotives had pulled their load across the bridge, and $5,706 had been collected in tolls from street traffic. The chapter also describes Chanute's appointment as chief engineer of the Missouri River, Fort Scott & Gulf Railroad and his involvement in construction of the Kansas City & Santa Fe Railroad, Galveston Railroad, and Atchison & Nebraska Railroad.

This chapter offers a compact analysis of the greed or money inscriptions made by Dave the Potter. “Cash wanted” and “Give me silver or; either Gold” are inscriptions in which the speaker brazenly announces a desire for cash despite the fact that slaves were not permitted to participate in a cash economy at the time. The announcement of economic desire brings into relief Dave’s status as an “ambiguous economic subject” whose relationship to commodity capitalism is challenged through his inscriptions. According to Santamarina, these rebellious inscriptions sallow Dave to challenge Lewis Miles’ ownership of himself and his jars. Through her analysis of the inscription’s engagement with commodity fantasy and economic reality, Santamarina demonstrates how Dave uses the inscription to make visible the “multivalent value-status” of his pots “in a space of contradiction between precapitalist and capitalist economies.” This space is then read back into the inscriptions not simply for its thematics but as a structuring principle of Dave the Potter’s inscriptive and ceramic practice.

During most of the twentieth century, the production of America’s consumer culture was centralized in New York to an extent unparalleled in the history of the modern United States. Within a few square miles were the headquarters of broadcast networks like NBC and CBS, the editorial offices of book and magazine publishers, major newspapers, and advertising and design agencies. Every day tens of thousands of writers, editors, artists, performers, technicians, secretaries, and other white-collar workers made advertisements, produced media content, and enhanced the appearance of goods in order to boost sales. While this center of creativity has often been portrayed as a smoothly running machine, within these offices many white-collar workers challenged the managers and executives who directed their labor. This book examines these workers and New York’s culture industries throughout the twentieth century. As manufacturers and retailers competed to attract consumers’ attention, their advertising expenditures financed the growth of enterprises engaged in the production of culture. With the shock of the Great Depression, employees in these firms organized unions to improve their working conditions; launched alternative media and cultural endeavors supported by public, labor, or cooperative patronage; and fought in other ways to expand their creative autonomy. As blacklisting and attacks on unions undermined these efforts after the Second World War, workers in advertising, design, publishing, and broadcasting found themselves constrained in their ability to respond to economic dislocations and to combat discrimination on the basis of gender and race in these fields of cultural production.

In Liberia’s diamond sector, the dynamics of the BOPC Group show how diamond mines remain vulnerable to takeover long after war has ended. From mining to taxing to exporting, West African governments have long struggled to control the supply of diamonds within their territories and the physical and social isolation of diamond mining areas has meant that they effectively govern themselves. This geographical buffer gives extralegal groups room to grow, develop organizational structures, and build up local networks of influence. Yet their claims to legitimacy are ultimately rooted in whether their mining activities are classified as legal or illegal, formal or informal, legitimate or illegitimate. Characterizing artisanal diamond mining as an “illicit” activity also feeds into the international community’s desire to sanitize the industry—even at the expense of miners’ livelihoods. This chapter demonstrates that these categorizations are not simply claims of law, but claims of power.

The publication deals with 229 species of Nepticulidae (or pygmy moths) from the Neotropics (i.e., the Neotropical and Ando-Patagonian regions) and adjacent areas. The species are illustrated with photographs or drawings of adult forewings, the male genitalia and, if available, leaf mines. In addition to the illustrated species review, the monograph announces about the first electronic diagnostic system (a free electronic tool on the internet) designed for the identification of species of Nepticulidae and includes chapters on the global biodiversity inventory, the collecting of adults and larvae of pygmy moths, preparation of micro-mounts of genitalia structures of Nepticulidae, global generic composition of the family, some particularities of Nepticulidae biology, a unique morphology guide based on the forewing pattern and male genitalia, descriptions of four newly named species, and a taxonomic checklist of the species currently known from the Neotropics and adjacent areas.

Hard coal mining is characterised by features that pose numerous challenges to its current operations and cause strategic and operational problems in planning its development. The most important of these include the high capital intensity of mining investment projects and the dynamically changing environment in which the sector operates, while the long-term role of the sector is dependent on factors originating at both national and international level. At the same time, the conditions for coal mining are deteriorating, the resources more readily available in active mines are being exhausted, mining depths are increasing, temperature levels in pits are rising, transport routes for staff and materials are getting longer, effective working time is decreasing, natural hazards are increasing, and seams with an increasing content of waste rock are being mined. The mining industry is currently in a very difficult situation, both in technical (mining) and economic terms. It cannot be ignored, however, that the difficult financial situation of Polish mining companies is largely exacerbated by their high operating costs. The cost of obtaining coal and its price are two key elements that determine the level of efficiency of Polish mines. This situation could be improved by streamlining the planning processes. This would involve striving for production planning that is as predictable as possible and, on the other hand, economically efficient. In this respect, it is helpful to plan the production from operating longwalls with full awareness of the complexity of geological and mining conditions and the resulting economic consequences. The constraints on increasing the efficiency of the mining process are due to the technical potential of the mining process, organisational factors and, above all, geological and mining conditions. The main objective of the monograph is to identify relations between geological and mining parameters and the level of longwall mining costs, and their daily output. In view of the above, it was assumed that it was possible to present the relationship between the costs of longwall mining and the daily coal output from a longwall as a function of onerous geological and mining factors. The monograph presents two models of onerous geological and mining conditions, including natural hazards, deposit (seam) parameters, mining (technical) parameters and environmental factors. The models were used to calculate two onerousness indicators, Wue and WUt, which synthetically define the level of impact of onerous geological and mining conditions on the mining process in relation to: —— operating costs at longwall faces – indicator WUe, —— daily longwall mining output – indicator WUt. In the next research step, the analysis of direct relationships of selected geological and mining factors with longwall costs and the mining output level was conducted. For this purpose, two statistical models were built for the following dependent variables: unit operating cost (Model 1) and daily longwall mining output (Model 2). The models served two additional sub-objectives: interpretation of the influence of independent variables on dependent variables and point forecasting. The models were also used for forecasting purposes. Statistical models were built on the basis of historical production results of selected seven Polish mines. On the basis of variability of geological and mining conditions at 120 longwalls, the influence of individual parameters on longwall mining between 2010 and 2019 was determined. The identified relationships made it possible to formulate numerical forecast of unit production cost and daily longwall mining output in relation to the level of expected onerousness. The projection period was assumed to be 2020–2030. On this basis, an opinion was formulated on the forecast of the expected unit production costs and the output of the 259 longwalls planned to be mined at these mines. A procedure scheme was developed using the following methods: 1) Analytic Hierarchy Process (AHP) – mathematical multi-criteria decision-making method, 2) comparative multivariate analysis, 3) regression analysis, 4) Monte Carlo simulation. The utilitarian purpose of the monograph is to provide the research community with the concept of building models that can be used to solve real decision-making problems during longwall planning in hard coal mines. The layout of the monograph, consisting of an introduction, eight main sections and a conclusion, follows the objectives set out above. Section One presents the methodology used to assess the impact of onerous geological and mining conditions on the mining process. Multi-Criteria Decision Analysis (MCDA) is reviewed and basic definitions used in the following part of the paper are introduced. The section includes a description of AHP which was used in the presented analysis. Individual factors resulting from natural hazards, from the geological structure of the deposit (seam), from limitations caused by technical requirements, from the impact of mining on the environment, which affect the mining process, are described exhaustively in Section Two. Sections Three and Four present the construction of two hierarchical models of geological and mining conditions onerousness: the first in the context of extraction costs and the second in relation to daily longwall mining. The procedure for valuing the importance of their components by a group of experts (pairwise comparison of criteria and sub-criteria on the basis of Saaty’s 9-point comparison scale) is presented. The AHP method is very sensitive to even small changes in the value of the comparison matrix. In order to determine the stability of the valuation of both onerousness models, a sensitivity analysis was carried out, which is described in detail in Section Five. Section Six is devoted to the issue of constructing aggregate indices, WUe and WUt, which synthetically measure the impact of onerous geological and mining conditions on the mining process in individual longwalls and allow for a linear ordering of longwalls according to increasing levels of onerousness. Section Seven opens the research part of the work, which analyses the results of the developed models and indicators in individual mines. A detailed analysis is presented of the assessment of the impact of onerous mining conditions on mining costs in selected seams of the analysed mines, and in the case of the impact of onerous mining on daily longwall mining output, the variability of this process in individual fields (lots) of the mines is characterised. Section Eight presents the regression equations for the dependence of the costs and level of extraction on the aggregated onerousness indicators, WUe and WUt. The regression models f(KJC_N) and f(W) developed in this way are used to forecast the unit mining costs and daily output of the designed longwalls in the context of diversified geological and mining conditions. The use of regression models is of great practical importance. It makes it possible to approximate unit costs and daily output for newly designed longwall workings. The use of this knowledge may significantly improve the quality of planning processes and the effectiveness of the mining process.

The book also traces the evolution of jazz styles and includes in-depth accounts of ragtime, blues, New Orleans jazz, Chicago jazz, swing and big band music, bebop, hard bop, cool jazz, avant-garde, jazz-rock fusion, and other subgenres and developments. The volume also provides a cultural and socioeconomic contextualization of the music, dealing with the broader political and social environment that gave birth to the music and shaped its development—both in the United States and within a global setting.

Motivated by the theory of turbulence in fluids, the physicist and chemist Lars Onsager conjectured in 1949 that weak solutions to the incompressible Euler equations might fail to conserve energy if their spatial regularity was below 1/3-Hölder. This book uses the method of convex integration to achieve the best-known results regarding nonuniqueness of solutions and Onsager's conjecture. Focusing on the intuition behind the method, the ideas introduced now play a pivotal role in the ongoing study of weak solutions to fluid dynamics equations. The construction itself—an intricate algorithm with hidden symmetries—mixes together transport equations, algebra, the method of nonstationary phase, underdetermined partial differential equations (PDEs), and specially designed high-frequency waves built using nonlinear phase functions. The powerful “Main Lemma”—used here to construct nonzero solutions with compact support in time and to prove nonuniqueness of solutions to the initial value problem—has been extended to a broad range of applications that are surveyed in the appendix. Appropriate for students and researchers studying nonlinear PDEs, this book aims to be as robust as possible and pinpoints the main difficulties that presently stand in the way of a full solution to Onsager's conjecture.

Into Russian Nature examines the history of the Russian national park movement. Russian biologists and geographers had been intrigued with the idea of establishing national parks before the Great October Revolution but pushed the Soviet government successfully to establish nature reserves (zapovedniki) during the USSR’s first decades. However, as the state pushed scientists to make zapovedniki more “useful” during the 1930s, some of the system’s staunchest defenders started supporting tourism in them. In the decades after World War II, the USSR experienced a tourism boom and faced a chronic shortage of tourism facilities. Also during these years, Soviet scientists took active part in Western-dominated international environmental protection organizations, where they became more familiar with national parks. In turn, they enthusiastically promoted parks for the USSR as a means to reconcile environmental protection and economic development goals, bring international respect to Soviet nature protection efforts, and help instill a love for the country’s nature and a desire to protect it in Russian/Soviet citizens. By the late 1980s, their supporters pushed transformative, and in some cases quixotic, park proposals. At the same time, national park opponents presented them as an unaffordable luxury during a time of economic struggle, especially after the USSR’s collapse. Despite unprecedented collaboration with international organizations, Russian national parks received little governmental support as they became mired in land-use conflicts with local populations. While the history of Russia’s national parks illustrates a bold attempt at reform, the state’s failure’s to support them has left Russian park supporters deeply disillusioned.

This book tells the story of the scientific talent and technological prowess of two nations that joined forces to connect themselves with a communications cable that would change the world. In 1855 an American visionary named Cyrus West Field, who knew nothing about telegraphy, sought to establish a monopoly on telegraphic revenues between North America and Europe. Field and the wealthy New Yorkers who formed the first Atlantic cable-laying company never suspected that spanning the vast and stormy Atlantic would require 11 years of frustration and horrific financial sacrifice. The enterprise would eventually engage some of the most brilliant minds in England, Scotland, and the United States, attracting men of science, men of wealth, and men of curiosity. Message time would be cut from more than four weeks to about two minutes. Such a feat would not have been possible without the massive ship the Great Eastern, designed by Isambard Kingdom Brunel, Britain’s foremost engineer, or the financial backing of Thomas Brassey, the era’s greatest builder of railroads. Despite four failed attempts and the enmity that developed between the Union and Great Britain during America’s Civil War, Field never stopped urging his British friends to perfect a cable that could function in water as deep as two and a half miles. Without the unified effort of this small cadre of determined engineers, decades may have passed before submarine cables became reliable. This is the story of these men, their ships, and the technology that made it all possible. Behind the scenes were tough and worthy competitors who tried to beat them to the punch, adding a sense of urgency to their monumental task. Some called the Atlantic cable the greatest feat of the 19th century—with good reason. It perfected transoceanic communications and connected the world with circuits in the sea.

We have long recognized technology as a driving force behind much historical and cultural change. The invention of the printing press initiated the Reformation. The development of the compass ushered in the Age of Exploration and the discovery of the New World. The cotton gin created the conditions that led to the Civil War. Now, in Beyond Engineering, science writer Robert Pool turns the question around to examine how society shapes technology. Drawing on such disparate fields as history, economics, risk analysis, management science, sociology, and psychology, Pool illuminates the complex, often fascinating interplay between machines and society, in a book that will revolutionize how we think about technology. We tend to think that reason guides technological development, that engineering expertise alone determines the final form an invention takes. But if you look closely enough at the history of any invention, says Pool, you will find that factors unrelated to engineering seem to have an almost equal impact. In his wide-ranging volume, he traces developments in nuclear energy, automobiles, light bulbs, commercial electricity, and personal computers, to reveal that the ultimate shape of a technology often has as much to do with outside and unforeseen forces. For instance, Pool explores the reasons why steam-powered cars lost out to internal combustion engines. He shows that the Stanley Steamer was in many ways superior to the Model T--it set a land speed record in 1906 of more than 127 miles per hour, it had no transmission (and no transmission headaches), and it was simpler (one Stanley engine had only twenty-two moving parts) and quieter than a gas engine--but the steamers were killed off by factors that had little or nothing to do with their engineering merits, including the Stanley twins' lack of business acumen and an outbreak of hoof-and-mouth disease. Pool illuminates other aspects of technology as well. He traces how seemingly minor decisions made early along the path of development can have profound consequences further down the road, and perhaps most important, he argues that with the increasing complexity of our technological advances--from nuclear reactors to genetic engineering--the number of things that can go wrong multiplies, making it increasingly difficult to engineer risk out of the equation. Citing such catastrophes as Bhopal, Three Mile Island, the Exxon Valdez, the Challenger, and Chernobyl, he argues that is it time to rethink our approach to technology. The days are gone when machines were solely a product of larger-than-life inventors and hard-working engineers. Increasingly, technology will be a joint effort, with its design shaped not only by engineers and executives but also psychologists, political scientists, management theorists, risk specialists, regulators and courts, and the general public. Whether discussing bovine growth hormone, molten-salt reactors, or baboon-to-human transplants, Beyond Engineering is an engaging look at modern technology and an illuminating account of how technology and the modern world shape each other.
