Classical Mechanics : An Introduction

This Upper-level Undergraduate And Beginning Graduate Textbook Primarily Covers The Theory And Application Of Newtonian And Lagrangian, But Also Of Hamiltonian Mechanics. In Addition, Included Are Elements Of Continuum Mechanics And The Accompanying Classical Field Theory, Wherein Four-vector Notation Is Introduced Without Explicit Reference To Special Relativity. The Author's Writing Style Attempts To Ease Students Through The Primary And Secondary Results, Thus Building A Solid Foundation For Understanding Applications. So The Text Is Thus Structured Around Developments Of The Main Ideas, Explicit Proofs, And Numerous Clarifications, Comments And Applications. Numerous Examples Illustrate The Material And Often Present Alternative Approaches To The Final Results. Frequent References Are Made Linking Mechanics To Other Fields Of Physics. These Lecture Notes Have Been Used Frequently By Students To Prepare For Written And/or Oral Examinations. Summaries And Problems Conclude Chapters And Appendices Supply Needed Background Topics.--jacket.

On this Textbook This book has evolved from the series of lecture notes that I had handed out to the physics students at the University of Regensburg in Bavaria,Germany. Overtheyears,variousbitsandpieceshadbeenaddedtothecontentsofthese lecture notes, and others had to be left out for reasons of time limitations. These notes di?ered from the common textbooks, and as the students seemed to like them, I have collected all those pieces in this book. The Scope of this Book The scope of this book is twofold. The reader can learn that alternative sets of the very few principles of Classical Mechanics carry on very far. Thus, the book contains an amount of applications of varying degrees of sophistication. Also, di?erent physical problems require di?erent methods for their solutions with varying degrees of mathematical sophistication. The Organization of this Book In order not to blur the physics with mathematical intricacies, the necessary mathematical techniques are transferred to appendices. The largest di?erence of this textbook from other books on Classical - chanics may be that I have tried to make a particularly strong separation between axioms and fundamental experiences, on the one hand, and between claims, their proofs, various comments, on the other, rather than telling a more or less continuous story. Also, frequent references are made to other parts of the book or to other physical disciplines. If needed, the reader can skip proofs, comments, applications, and footnotes and thus follow only the main ideas. 1-systems are a mathematical formalism which was proposed by Aristid 1indenmayer in 1968 as a foundation for an axiomatic theory of develop­ ment. The notion promptly attracted the attention of computer scientists, who investigated 1-systems from the viewpoint of formal language theory. This theoretical line of research was pursued very actively in the seventies, resulting in over one thousand publications. A different research direction was taken in 1984 by Alvy Ray Smith, who proposed 1-systems as a tool for synthesizing realistic images of plants and pointed out the relationship between 1-systems and the concept of fractals introduced by Benoit Mandel­ brot. The work by Smith inspired our studies of the application of 1-systems to computer graphics. Originally, we were interested in two problems: • Can 1-systems be used as a realistic model of plant species found in nature? • Can 1-systems be applied to generate images of a wide class of fractals? It turned out that both questions had affirmative answers. Subsequently we found that 1-systems could be applied to other areas, such as the generation of tilings, reproduction of a geometric art form from East India, and synthesis of musical scores based on an interpretation of fractals. This book collects our results related to the graphical applications of- systems. It is a corrected version of the notes which we prepared for the ACM SIGGRAPH'88 course on fractals. 1-systems are a mathematical formalism which was proposed by Aristid 1indenmayer in 1968 as a foundation for an axiomatic theory of develop- ment.
