This book offers a concise introduction to the angular momentum, one of the most fundamental quantities in all of quantum mechanics. Beginning with the quantization of angular momentum, spin angular momentum, and the orbital angular momentum, the author goes on to discuss the Clebsch-Gordan coefficients for a two-component system. After developing the necessary mathematics, specifically spherical tensors and tensor operators, the author then investigates the 3-j, 6-j, and 9-j symbols. Throughout, the author provides practical applications to atomic, molecular, and nuclear physics. These include partial-wave expansions, the emission and absorption of particles, the proton and electron quadrupole moment, matrix element calculation in practice, and the properties of the symmetrical top molecule.

Delivering consistent, profitable growth is the #1 non-negotiable imperative facing today's business leaders. Many firms struggle to meet it. Only a rare few consistently achieve it. How do they do it? The answer lies in a tremendously potent but little-understood force: momentum. Momentum feeds on itself: if nurtured properly, it accumulates even more power from its own success, creating new value with unparalleled efficiency. In The Momentum Effect, INSEAD's Jean-Claude Larreche reveals exactly how to build and preserve business momentum, and use it to deliver growth that gets you noticed, year after year after year. Larreche begins by demonstrating the powerful, hidden role of momentum in value creation and why it's more important than innovation, marketing excellence, or even customer focus. Next, one at a time he introduces eight tightly linked "building blocks" of momentum strategy. You'll learn through dozens of case studies: surprising new insights into familiar companies like IBM and Toyota, as well as remarkable, under-recognized leaders like Rentokil and First Direct. Last but not least, Larreche demonstrates how to build the unique leadership competencies needed to implement and sustain a winning momentum strategy: not just for years, but for decades.

Spin angular momentum of photons and the associated polarization of light has been known for many years. However, it is only over the last decade or so that physically realizable laboratory light beams have been used to study the orbital angular momentum of light. In many respects, orbital and spin angular momentum behave in a similar manner, but they differ significantly in others. In particular, orbital angular momentum offers exciting new possibilities with respect to the optical manipulation of matter and to the study of the entanglement of photons. Bringing together 44 landmark papers, Optical Angular Momentum offers the first comprehensive overview of the subject as it has developed. It chronicles the first decade of this important subject and gives a definitive statement of the current status of all aspects of optical angular momentum. In each chapter the editors include a concise introduction, putting the selected papers into context and outlining the key articles associated with this aspect of the subject.

"Presents the fundamentals of momentum, heat, and mass transfer from both a microscopic and a macroscopic perspective. Features a large number of idealized and real-world examples that we worked out in detail."

This book gives a complete account of electron momentum spectroscopy to date. It describes in detail the construction of spectrometers and the acquisition and reduction of cross-section data, explaining the quantum theory of the reaction and giving experimental verification.

Do you wonder why some ideas go viral and others sink? Why one political candidate soars while another fails to gain traction? Why one product becomes an instant rage, while its competitor struggles to stay above water? What is the secret to momentum? Many people believe that momentum is driven by emotion and is unpredictable, but as Mike Berland, the internationally recognized pollster and strategic advisor, has discovered, it’s actually a science, with easily analyzed metrics. In Maximum Momentum: How to Get It, How to Keep It, Berland reveals the key to momentum, beginning with the simple physics formula— mass x velocity. He then develops a Momentum Matrix—five signals that decode the science into effective measures. Maximum Momentum is a lively examination of hot trends in the current arena—from politics to society to business to sports. Using colorful graphics to underscore the stories, Berland examines the people, issues, movements and products that most captivate Americans.

The goal of this book is to serve both as a practical technical reference and a resource for gaining a fuller understanding of the state of the art of spacecraft momentum control systems, specifically looking at control moment gyroscopes (CMGs). As a result, the subject matter includes theory, technology, and systems engineering. The authors combine material on system-level architecture of spacecraft that feature momentum-control systems with material about the momentum-control hardware and software. This also encompasses material on the theoretical and algorithmic approaches to the control of space vehicles with CMGs. In essence, CMGs are the attitude-control actuators that make contemporary highly agile spacecraft possible. The rise of commercial Earth imaging, the advances in privately built spacecraft (including small satellites), and the growing popularity of the subject matter in academic circles over the past decade argues that now is the time for an in-depth treatment of the topic. CMGs are augmented by reaction wheels and related algorithms for steering all such actuators, which together comprise the field of spacecraft momentum control systems. The material is presented at a level suitable for practicing engineers and those with an undergraduate degree in mechanical, electrical, and/or aerospace engineering.

The first comprehensive and authoritative coverage of the angular momentum of light, illustrating both its theoretical and applied aspects.

A treatment of the transport and transfer processes of heat, mass and momentum in terms of their analogy. The processes are described with the help of macro and micro balances which in many cases lead to differential equations. This way, the textbook also prepares for Computational Fluid Dynamics techniques. The topics of the five chapters of the textbook are: Balances: shape and recipe, mass balance, residence time distribution, energy and heat balances, Bernoulli equation, momentum balances Molecular transport, dimensional analysis, forces on immersed objects Heat transport: steady-state and unsteady conduction, the general heat transport equation, forced and free convective heat transport, radiant heat transport Mass transport: steady-state and unsteady diffusion, the general mass transport equation, mass transfer across a phase interface, convective mass transport, wet bulb temperature Fluid mechanics: flow meters, pressure drop, packed beds, laminar flow of Newtonian and non-Newtonian fluids, Navier-Stokes equations The leading idea behind this textbook is to train students in solving problems where transport phenomena are key. To this end, the textbook comprises almost 80 problems with solutions.
