Replication, the independent confirmation of experimental results and conclusions, is regarded as the "gold standard" in science. This book examines the question of successful or failed replications and demonstrates that that question is not always easy to answer. It presents clear examples of successful replications, the discoveries of the Higgs boson and of gravity waves. Failed replications include early experiments on the Fifth Force, a proposed modification of Newton's Law of universal gravitation, and the measurements of "G," the constant in that law. Other case studies illustrate some of the difficulties and complexities in deciding whether a replication is successful or failed. It also discusses how that question has been answered. These studies include the "discovery" of the pentaquark in the early 2000s and the continuing search for neutrinoless double beta decay. It argues that although successful replication is the goal of scientific experimentation, it is not always easily achieved.

This book describes modern focused ion beam microscopes and techniques and how they can be used to aid materials metrology and as tools for the fabrication of devices that in turn are used in many other aspects of fundamental metrology. Beginning with a description of the currently available instruments including the new addition to the field of plasma-based sources, it then gives an overview of ion solid interactions and how the different types of instrument can be applied. Chapters then describe how these machines can be applied to the field of materials science and device fabrication giving examples of recent and current activity in both these areas.

The Basics of Polymers is written exclusively about chemical methods of polymer testing aimed at producing a high degree of manufacturing and quality control of polymer products. Polymer testing has assumed importance for industries dependent on polymers and additives as key product components. The text is intended to serve as a handbook for students, engineers, and people involved in polymer synthesis and laboratory work. This book provides information on identification and characterization of polymers by chemical methods. Specifically aimed at graduate-level students, its style of presentation is practical, making it easier to grasp. The author hopes this book will encourage and foster continuing method development and application of chemical methods for characterizing polymers. Education and training of people being of paramount importance, it is also valuable to all educators/processors as a tremendous resource that answers commonly asked questions.

This book is written specifically for the students of intermediate (or Higher Secondary) standard. Keeping in view of the standard of their education, the book is written in simple and lucid language. Each of the experiments written in the book comprises necessary introductions and theoretical details alongwith stepwise procedure for performing practicals, so that they can easily follow this book in their Laboratory classes. Whenever needed the experiments are followed by Viva-Vice questions along with their answers. These questions will help the students to guide them for their college practical examinations in advance.

Learn about the Physics of Balls Focus: Projectile Motion and Collisions Force, Trajectory, Velocity, & Acceleration In this book, readers gain access to real scientific data pertaining to balls, promoting graph-reading, comparison, contrast, and calculation skills. Graphs show data from the following scientific instruments: Video Analysis This book allows readers to analyze real data without purchasing expensive lab equipment. Graphs show the motion of a tennis ball, cricket ball, racquetball, lacrosse ball, softball, field hockey ball, street hockey balls (high and low density), and Swedish hockey puck-handling ball as they fly through the air. Some graphs also show the balls hitting a wall and bouncing back. The graphs and data contained in this book can be used by teachers and parents to supplement traditional lesson plans. Bonus Material: For comparison and contrast, a selection of balls from Volume 3 are provided. Graphs show data from a basketball, soccer ball, volleyball, dodge ball, 3 baseballs (official, safety, and plastic), 3 golf balls (official, foam and plastic), a ping pong ball, and a plastic apple as they fly through the air. Several of these graphs also show the trajectory of balls bouncing off a wall.

Photoemission (also known as photoelectron) spectroscopy refers to the process in which an electron is removed from a specimen after the atomic absorption of a photon. The first evidence of this phenomenon dates back to 1887 but it was not until 1905 that Einstein offered an explanation of this effect, which is now referred to as ""the photoelectric effect"".Quantitative Core Level Photoelectron Spectroscopy: A Primer tackles the pragmatic aspects of the photoemission process with the aim of introducing the reader to the concepts and instrumentation that emerge from an experimental approach. The basic elements implemented for the technique are discussed and the geometry of the instrumentation is explained. The book covers each of the features that have been observed in the X-ray photoemission spectra and provides the tools necessary for their understanding and correct identification. Charging effects are covered in the penultimate chapter with the final chapter bringing closure to the basic uses of the X-ray photoemission process, as well as guiding the reader through some of the most popular applications used in current research.
