Essential Dynamics and Relativity

Essential Dynamics and Relativity provides students with an introduction to the core aspects of dynamics and special relativity. The author reiterates important ideas and terms throughout and covers concepts that are often missing from other textbooks at this level. He also places each topic within the wider constructs of the theory, without jumping from topic to topic to illustrate a point.The first section of the book focuses on dynamics, discussing the basic aspects of single particle motion and analyzing the motion of multi-particle systems. The book also explains the dynamical behavior of both composite bodies (rigid bodies) and objects in non-inertial frames of reference (rotating reference frames).The second section concentrates on relativity. The author describes the ideas leading to the inception of special relativity. He also formulates fundamental aspects, such as time dilation, length contraction, Lorentz transformations, and the visual aids of Minkowski diagrams, necessary to develop more sophisticated ideas. He then develops the concepts within the context of relativistic mechanics.With many examples throughout and exercises at the end of each chapter, this text makes the often daunting and confusing ideas of dynamics and special relativity accessible to undergraduate students studying the subjects for the first time.

Detailing powerful methods for reducing the energy costs associated with operating a data center, Making Your Data Center Energy Efficient examines both equipment and building facilities. It reviews the rationale for conserving energy and demonstrates how conservation and careful equipment selection can lead to significant improvements to your bottom line. For those not well-versed in financial or energy terms, the first two chapters provide a detailed discussion of the terms associated with different types of energy, as well as how to compute the return on investment for energy conservation efforts. The text includes tables of monthly expenses associated with operating equipment that will help you convert problems into simple table lookup processes. Among the money-saving topics discussed, it considers:How to minimize the energy consumption of a wide range of devices A little-understood topic that can make a big impact on energy costs general heating and cooling Techniques required to effectively monitor different types of meters Phantom energy usage and methods for minimizing its cost to your organizationRecognizing that most readers may not have direct control over the selection of a furnace or hot water heater, the book provides you with the ability to recognize the efficiencies and inefficiencies of various types of devices, so you can provide input into the decision-making process. From replacing lighting to consolidation and virtualization, it provides you with the well-rounded understanding needed to properly manage all aspects of the energy consumed in your data center.
