The content of this book is mechanics ( includes the rotation of rigid body), mechanical vibration and mechanical wave, thermodynamics and statistical physics, wave optics, electromagnetism, modern physics foundation and physics in robust Growth in turn, a total of 17 chapters. There are the questions after each section and the exercises after each chapter except Chapter 17, and there is the reference answers to all exercises at the end of this book. Reading this book requires the reader have the basic knowledge of calculus and vector operation. The outstanding characteristic of this book different from general physics textbooks is that the proving of each related theorem is given in the book except the basic principle summarized directly from practice, such as Newton's law, and some of them are the research results of the editors of the book. Although the number of pages of this book significantly less than that of general physics textbooks, but its content is more complete and systematic, and more conducive to teaching and self-study.
