Helping coaches and players streamline their learning systems, improve their performance, and further their understanding and enjoyment of the game, this book provides an entertaining and enlightening look at the physics behind how to use a racquet to change the speed and direction of a tennis ball. Distinguishing the science from the folklore and myth, it makes the physics of tennis understandable to players of all skill levels. Important issues such as the role of string tension, the meaning of power, the importance of swing weight, and the relevance of the various sweet spots are addressed. Athletes are shown how to play better tennis by obeying the laws of the universe, optimizing equipment for ultimate performance, and understanding the dynamics of tennis events. From speed-to-spin ratios and shock vibration scales to choosing string on a moist day, this guide covers it all.

This book describes the physics of baseball and softball, assuming that the reader has a basic background in both physics and mathematics. The physics will be explained in a conversational style, with words and illustrations, so that the explanations make sense. The book provides an excellent opportunity to explain physics at a relatively simple level, even though the primary objective is to explain the many subtle features concerning the physics of baseball. For those readers who already know quite a bit of physics and who will be comfortable with mathematical equations, additional material of this nature will be provided in appendices. The latest research findings and statistical data have been incorporated by the author. The book also contains many simple experiments that the reader can perform to convince themselves that the effects described do indeed exist.

A key objective of the Central European Economies (CEE) on their transition path from planned to more market-oriented economies has been membership of the European Union (EU). The start of Economic and Monetary Union (EMU) in 1999 has added membership of the EMU to the agenda for the CEEs. The task of the so-called Visegrad countries (the Czech and Slovak Republics, Hungary and Poland) of preparing for EU and EMU membership is the key theme underlying the papers contained in this volume. There are many issues to be resolved before the Visegrad countries are admitted into the EU, and this volume focuses on the issues relating to macroeconomic policies and financial sector structures. The chapters of Central Europe Towards Monetary Union: Macroeconomic Underpinnings and Financial Reputation contain new theoretical and empirical results and also comprehensive institutional overviews. The intended readership of the book is policy makers and economists working in the academic and financial sectors.

"What are the single most important variables in racquet performance? What racquet and string features combine to provide the most control, comfort, and feel? How can a player create maximum spin? "This informative primer answers these and other elusive equipment and performance-related questions that perennially plague hackers and experts alike. A simplified, layperson's companion to the authors' previous work, "The Physics and Technology of Tennis," this conveniently sized guide to selecting racquets and strings includes bite-sized explanations of the possible expectations of equipment choices.

For 25 years, theory about the causes of, and possible solutions to, the problem of unemployment has been dominated by Phelps' and Friedman's natural rate of unemployment hypothesis. This postulates that the equilibrium rate of unemployment consistent with steady inflation is determined by structural variables: sustainable reductions in unemployment can be achieved only by measures to change underlying microeconomic structures, such as benefit and pay bargaining systems. Belief in the hypothesis has faltered since the 1980s, the hypothesis being unable to explain the dramatic upward shifts in European unemployment rates. These essays reflect upon the fundamental structures underlying the hypothesis, assess the related evidence, and look forwards, suggesting possible modifications. In contrast to the single rate postulated by the natural rate hypothesis, several of the contributors propose that there are ranges of unemployment rates consistent with steady inflation.
