Introduction to Mechanics and Symmetry

Symmetry and mechanics have been close partners since the time of the founding masters: Newton, Euler, Lagrange, Laplace, Poisson, Jacobi, Hamilton, Kelvin, Routh, Riemann, Noether, Poincar´e, Einstein, Schr¨odinger, Cartan, Dirac, and to this day, symmetry has continued to play a strong role, especially with the modern work of Kolmogorov, Arnold, Moser, Kirillov, Kostant, Smale, Souriau, Guillemin, Sternberg, and many others. This book is about these developments, with an emphasis on concrete applications that we hope will make it accessible to a wide variety of readers, especially senior undergraduate and graduate students in science and engineering.

INTRODUCTION TO LAGRANGIAN AND HAMILTONIAN MECHANICS

Minimum principles have been invoked throughout the history of Physics to explain the behavior of light and particles. In one of its earliest form, Heron of Alexandria (ca. 75 AD) stated that light travels in a straight line and that light follows a path of shortest distance when it is reflected by a mirror. In 1657, Pierre de Fermat (1601-1665) stated the Principle of Least Time, whereby light travels between two points along a path that minimizes the travel time, to explain Snell’s Law (Willebrord Snell, 1591-1626) associated with light refraction in a stratified medium.

INTRODUCTION TO GENERAL RELATIVITY

General relativity is a beautiful scheme for describing the gravitational fieldandthe equations it obeys. Nowadays this theory is often used as a prototype for other, more intricate constructions to describe forces between elementary particles or other branches of fundamental physics. This is why in an introduction to general relativity it is of importance to separate as clearly as possible the various ingredients that together give shape to this paradigm. After explaining the physical motivations we first introduce curved coordinates, then addto this the notion of an affine connection fieldandonly as a later step addto that the metric field. One then sees clearly how space and time get more and more structure, until finally all we have to do is deduce Einstein’s field equations.

Крокодил Гена и его друзья

Однажды одинокий крокодил Гена решил изменить свою жизнь! Он повесил объявление о поиске друзей и с тех пор ни минуты не знал покоя! Ведь в городе оказалось много желающих подружиться: неизвестный науке зверек Чебурашка, долговязая жирафа Анита, интеллигентный лев Чандр и еще много-много животных, девчонок и мальчишек! Так много-много, что пришлось строить Дом Дружбы, чтобы было где встречаться такой огромной компанией!

Introduction to Fourier Optics

Since the subject covered is Fourier Optics, it is natural that the methods of Fourier analysis play a key role as the underlying analytical structure of our treatment. Fourier analysis is a standard part of the background of most physicists and engineers. The theory of linear systems is also familiar, especially to electrical engineers. Chapter 2 reviews the necessary mathematical background. For those not already familiar with Fourier analysis and linear systems theory, it can serve as the outline for a more detailed study that can be made with the help of other textbooks explicitly aimed at this subject. Ample references are given for more detailed treatments of this material. For those who have already been introduced to Fourier analysis and linear systems theory, that experience has usually been with functions of a single independent variable, namely time. The material presented in Chapter 2 deals with the mathematics in two spatial dimensions (as is necessary for most problems in optics), yielding an extra richness not found in the standard treatments of the one-dimensional theory.

Introduction to Continuum Mechanic

The first edition of this book was published in 1974, nearly twenty years ago. It was written as a text book for an introductory course in continuum mechanics and aimed specifically at the junior and senior level of undergraduate engineering curricula which choose to introduce to the students at the undergraduate level the general approach to the subject matter of continuum mechanics. We are pleased that many instructors of continuum mechanics have found this little book serves that purpose well. However, we have also understood that many instructors have used this book as one of the texts for a beginning graduate course in continuum mechanics. It is this latter knowledge that has motivated us to write this new edition. In this present edition, we have included materials which we feel are suitable for a beginning graduate course in continuum mechanics.
