Why Quantum Mechanics is Necessary for Describing Molecular Properties. We know that all molecules are made of atoms which, in turn, contain nuclei and electrons. As I discuss in this introductory section, the equations that govern the motions of electrons and of nuclei are not the familiar Newton equations

This book is designed to help the engineer understand the principles of metal form￾ing and to analyze forming problems – both the mechanics of forming processes and how the properties of metals interact with the processes. In this book, an entire chapter is devoted to forming limit diagrams and various aspects of stamping and another to other sheet forming operations. Sheet testing is covered in a separate chapter. Coverage of sheet metal properties has been expanded. Interesting end￾of-chapter notes have been added throughout, as well as references. More than 200 end-of-chapter problems are also included

When one is faced with a condensed-phase system, usually containing many molecules, that is at or near thermal equilibrium, it is not necessary or even wise to try to describe it in terms of quantum wave functions or even classical trajectories of all of the constituent molecules. Instead, the powerful tools of statistical mechanics

We theoretically study the dynamics of a pair of coupled pendulums subject to a peri￾odic temporal modulation of their oscillation frequency. Inspired from analogous developments in quantum mechanics, we anticipate dynamical localization and dynamical isolation effects, as well as the occurrence of non-trivial coupling phases. Perspectives in the direction of studying synthetic gauge fields in a classical mechanics context are outlined
