| back of the envelope analysis: Back-of-the-Envelope Physics Clifford Swartz, 2004-12-01 From an award-winning teacher, “a delightful and instructive accessory to an introductory physics course” (Physics World). Physicists use “back-of-the-envelope” estimates to check whether or not an idea could possibly be right. In many cases, the approximate solution is all that is needed. This compilation of 101 examples of back-of-the-envelope calculations celebrates a quantitative approach to solving physics problems. Drawing on a lifetime of physics research and nearly three decades as the editor of The Physics Teacher, Clifford Swartz—a winner of two awards from the American Association of Physics Teachers—provides simple, approximate solutions to physics problems that span a broad range of topics. What note do you get when you blow across the top of a Coke bottle? Could you lose weight on a diet of ice cubes? How can a fakir lie on a bed of nails without getting hurt? Does draining water in the northern hemisphere really swirl in a different direction than its counterpart below the equator? In each case, only a few lines of arithmetic and a few natural constants solve a problem to within a few percent. Covering such subjects as astronomy, magnetism, optics, sound, heat, mechanics, waves, and electricity, this book provides a rich source of material for teachers and anyone interested in the physics of everyday life. “This is a book that will help make the study of physics fun and relevant.” —Mark P. Silverman, author of Waves and Grains: Reflections on Light and Learning |
| back of the envelope analysis: Aerospace Engineering on the Back of an Envelope Irwin E. Alber, 2012-03-05 Engineers need to acquire “Back-of-the-Envelope” survival skills to obtain rough quantitative answers to real-world problems, particularly when working on projects with enormous complexity and very limited resources. In the case studies treated in this book, we show step-by-step examples of the physical arguments and the resulting calculations obtained using the quick-fire method. We also demonstrate the estimation improvements that can be obtained through the use of more detailed physics-based Back-of-the-Envelope engineering models. These different methods are used to obtain the solutions to a number of design and performance estimation problems arising from two of the most complex real-world engineering projects: the Space Shuttle and the Hubble Space Telescope satellite. |

| back of the envelope analysis: Analysis and Public Policy Stuart Shapiro, 2016-02-26 How do we incorporate analytical thinking into public policy decisions? Stuart Shapiro confronts this issue in Analysis and Public Policy by looking at various types of analysis, and discussing how they are used in regulatory policy-making in the US. By looking at the successes and failures of incorporating cost-benefit analysis, risk assessment, and environmental impact assessment, he draws broader lessons on its use, focusing on the interactions between analysis and political factors, legal structures and bureaucratic organizations as possible areas for reform. Utilizing empirical and qualitative research, Shapiro analyzes four different forms of analysis: cost-benefit analysis, risk assessment, environmental impact assessment, and impact analysis. After interviewing nearly fifty individuals who have served in high levels of government, and who have made countless regulatory policy decisions in their careers, Shapiro argues that advocates must become less ambitious and should craft requirements for simpler and clearer analysis. Such analysis, particularly if informed by public participation, can do a great deal to improve government decisions. As this book details the relationship between analysis and institutional factors such as politics, bureaucracy, and law, it is appropriate for a variety of readers, such as scholars of policy, students, scholars of regulation, and congressional and state legislative staff looking to create new analytical requirements. |
| back of the envelope analysis: Program Evaluation Robert L. Schalock, C.V.D. Thornton, 2013-11-11 This book is written to help human service program administrators either in terpret or conduct program evaluations. Our intended audience includes admin istrators and those students being trained for careers in human services administration. Our focus is on persons interested in assessing programs in which people work with people to improve their condition. The book's title, Program Evaluation: A Field Guide for Administrators, describes how we hope you use this book-as a tool. In writing the book, we have attempted to meet the needs of persons who have to conduct program evaluations as well as those who must use those evaluations. Hence, we have attempted to make the book user friendly. You will find, for example, numer ous guidelines, cautions, and specific suggestions. Use the book actively. Our primary motive is to help administrators make better decisions. In fact, the primary reason for program evaluation is to help program administrators make good decisions. These decisions often must balance the goals of equity (or fairness in the distribution of goods and services among people in the economy), efficiency (obtaining the most output for the least resources), and political feasi bility. Take, for example, the administrator who must decide between a new program favored by some of the program's constituents, and maintaining the status quo, which is favored by other constituents. |

| back of the envelope analysis: Competition Policy Analysis Kai Hüschelrath, 2008-09-08 Competition policy is an integral and prominent part of economic policy-making in the European Union. The EU Treaty prescribes its member states to conduct economic policy ‘in accordance with the principle of an open market economy with free competition’. More precisely, the goal of EU competition policy is “to defend and develop effective competition in the common market” (European Commission, 2000: 7). Under its Commissioners van Miert, Monti and, most - cently, Kroes the EU Commission has stepped up its effort to pursue and achieve the aforementioned goal. A number of so-called hard-core cartels, such as the - torious “vitamin cartel” led by Roche, have been detected, tried in violation of Art. 81 of the Maastricht Accord and punished with severe fines. Also Microsoft was hit hard by the strong hand of the Commission having been severely fined for - ploiting a dominant market position. Economic analysis has been playing an increasingly significant role in the Commission’s examination of competition law cases. This holds true in particular for merger control. Here, however, the Commission has had to accept some poi- ant defeats in court, such as the Court’s reversals of Airtours-First Choice or GE- Honeywell. Among other things, the European Court of Justice found the e- nomic analysis as conducted by the EU’s Directorate General for Competition to be flawed and the conclusions drawn not to be convincing. These rejections by the courts have stirred up the scholarly debate on the conceptual foundations of Eu- pean competition policy. |

| back of the envelope analysis: Data Analytics Subhashish Samaddar, Satish Nargundkar, 2019-02-18 If you are a manager who receives the results of any data analyst’s work to help with your decision-making, this book is for you. Anyone playing a role in the field of analytics can benefit from this book as well. In the two decades the editors of this book spent teaching and consulting in the field of analytics, they noticed a critical shortcoming in the communication abilities of many analytics professionals. Specifically, analysts have difficulty in articulating in business terms what their analyses showed and what actionable recommendations were made. When analysts made presentations, they tended to lapse into the technicalities of mathematical procedures, rather than focusing on the strategic and tactical impact and meaning of their work. As analytics has become more mainstream and widespread in organizations, this problem has grown more acute. Data Analytics: Effective Methods for Presenting Results tackles this issue. The editors have used their experience as presenters and audience members who have become lost during presentation. Over the years, they experimented with different ways of presenting analytics work to make a more compelling case to top managers. They have discovered tried and true methods for improving presentations, which they share. The book also presents insights from other analysts and managers who share their own experiences. It is truly a collection of experiences and insight from academics and professionals involved with analytics. The book is not a primer on how to draw the most beautiful charts and graphs or about how to perform any specific kind of analysis. Rather, it shares the experiences of professionals in various industries about how they present their analytics results effectively. They tell their stories on how to win over audiences. The book spans multiple functional areas within a business, and in some cases, it discusses how to adapt presentations to the needs of audiences at different levels of management. |
| back of the envelope analysis: Foundations of Dynamic Economic Analysis Michael R. Caputo, 2005-01-10 Foundations of Dynamic Economic Analysis presents a modern and thorough exposition of the fundamental mathematical formalism used to study optimal control theory, i.e., continuous time dynamic economic processes, and to interpret dynamic economic behavior. The style of presentation, with its continual emphasis on the economic interpretation of mathematics and models, distinguishes it from several other excellent texts on the subject. This approach is aided dramatically by introducing the dynamic envelope theorem and the method of comparative dynamics early in the exposition. Accordingly, motivated and economically revealing proofs of the transversality conditions come about by use of the dynamic envelope theorem. Furthermore, such sequencing of the material naturally leads to the development of the primal-dual method of comparative dynamics and dynamic duality theory, two modern approaches used to tease out the empirical content of optimal control models. The stylistic approach ultimately draws attention to the empirical richness of optimal control theory, a feature missing in virtually all other textbooks of this type. |

| back of the envelope analysis: The Making of the Atomic Bomb Richard Rhodes, 2012-09-18 **Winner of the Pulitzer Prize, the National Book Award, and the National Book Critics Circle Award** The definitive history of nuclear weapons—from the turn-of-the-century discovery of nuclear energy to J. Robert Oppenheimer and the Manhattan Project—this epic work details the science, the people, and the sociopolitical realities that led to the development of the atomic bomb. This sweeping account begins in the 19th century, with the discovery of nuclear fission, and continues to World War Two and the Americans’ race to beat Hitler’s Nazis. That competition launched the Manhattan Project and the nearly overnight construction of a vast military-industrial complex that culminated in the fateful dropping of the first bombs on Hiroshima and Nagasaki. Reading like a character-driven suspense novel, the book introduces the players in this saga of physics, politics, and human psychology—from FDR and Einstein to the visionary scientists who pioneered quantum theory and the application of thermonuclear fission, including Planck, Szilard, Bohr, Oppenheimer, Fermi, Teller, Meitner, von Neumann, and Lawrence. From nuclear power’s earliest foreshadowing in the work of H.G. Wells to the bright glare of Trinity at Alamogordo and the arms race of the Cold War, this dread invention forever changed the course of human history, and The Making of The Atomic Bomb provides a panoramic backdrop for that story. Richard Rhodes’s ability to craft compelling biographical portraits is matched only by his rigorous scholarship. Told in rich human, political, and scientific detail that any reader can follow, The Making of the Atomic Bomb is a thought-provoking and masterful work. |

The report presents what is known and unknown about this waste and contamination and how it may affect public health. Because so many factors are involved and science cannot provide absolute answers to many questions, this study emphasizes the need for care, caution, awareness, and prudence. It also stresses the need for a stable and enduring institutional framework and international cooperation for long term observation and monitoring. |
| back of the envelope analysis: The Interface Envelope James Ash, 2015-02-26 In The Interface Envelope, James Ash develops a series of concepts to understand how digital interfaces work to shape the spatial and temporal perception of players. Drawing upon examples from videogame design and work from post-phenomenology, speculative realism, new materialism and media theory, Ash argues that interfaces create envelopes, or localised foldings of space time, around which bodily and perceptual capacities are organised for the explicit production of economic profit. Modifying and developing Bernard Stiegler's account of psychopower and Warren Neidich's account of neuropower, Ash argues the aim of interface designers and publishers is the production of envelope power. Envelope power refers to the ways that interfaces in games are designed to increase users perceptual and habitual capacities to sense difference. Examining a range of examples from specific videogames, Ash identities a series of logics that are key to producing envelope power and shows how these logics have intensified over the last thirty years. In turn, Ash suggests that the logics of interface envelopes in videogames are spreading to other types of interface. In doing so life becomes enveloped as the environments people inhabit becoming increasingly loaded with digital interfaces. Rather than simply negative, Ash develops a series of responses to the potential problematics of interface envelopes and envelope power and emphasizes their pharmacological nature. |

| back of the envelope analysis: Product Research N. R. Srinivasa Raghavan, John A. Cafeo, 2010-03-11 7. 1. 1 Background Uncertainty can be considered as the lack of adequate information to make a decision. It is important to quantify uncertainties in mathematical models used for design and optimization of nondeterministic engineering systems. In general, - certainty can be broadly classi?ed into three types (Bae et al. 2004; Ha-Rok 2004; Klir and Wierman 1998; Oberkampf and Helton 2002; Sentz 2002). The ?rst one is aleatory uncertainty (also referred to as stochastic uncertainty or inherent - certainty) – it results from the fact that a system can behave in random ways. For example, the failure of an engine can be modeled as an aleatory uncertaintybecause the failure can occur at a random time. One cannot predict exactly when the engine will fail even if a large quantity of failure data is gathered (available). The second one is epistemic uncertainty (also known as subjective uncertainty or reducible - certainty) – it is the uncertainty of the outcome of some random event due to lack of knowledge or information in any phase or activity of the modeling process. By gaining information about the system or environmental factors, one can reduce the epistemic uncertainty. For example, a lack of experimental data to characterize new materials and processes leads to epistemic uncertainty. |
| back of the envelope analysis: Software Architecture in Practice Len Bass, Paul Clements, Rick Kazman, 2012-09-25 The award-winning and highly influential Software Architecture in Practice, Third Edition, has been substantially revised to reflect the latest developments in the field. In a real-world setting, the book once again introduces the concepts and best practices of software architecture—how a software system is structured and how that system’s elements are meant to interact. Distinct from the details of implementation, algorithm, and data representation, an architecture holds the key to achieving system quality, is a reusable asset that can be applied to subsequent systems, and is crucial to a software organization’s business strategy. The authors have structured this edition around the concept of architecture influence cycles. Each cycle shows how architecture influences, and is influenced by, a particular context in which architecture plays a critical role. Contexts include technical environment, the life cycle of a project, an organization’s business profile, and the architect’s professional practices. The authors also have greatly expanded their treatment of quality attributes, which remain central to their architecture philosophy—with an entire chapter devoted to each attribute—and broadened their treatment of architectural patterns. If you design, develop, or manage large software systems (or plan to do so), you will find this book to be a valuable resource for getting up to speed on the state of the art. Totally new material covers Contexts of software architecture: technical, project, business, and professional Architecture competence: what this means both for individuals and organizations The origins of business goals and how this affects architecture Architecturally significant requirements, and how to determine them Architecture in the life cycle, including generate-and-test as a design philosophy; architecture conformance during implementation; architecture and testing; and architecture and agile development Architecture and current technologies, such as the cloud, social networks, and end-user devices |
