دانلود کتاب الکترودینامیک کلاسیک، راهنمای مختصر و مفید

This book grew out of my lectures notes used in teaching the course PH4506 Electrodynamics at Nanyang Technological University (NTU), School of Physical and Mathematical Sciences (SPMS). By tradition, electrodynamics is taught in year 4 but personally I feel that it is too late as students are working on their final year projects (FYPs) at the same time where electrodynamics is clearly an essential foundational topic. This is especially true if their FYPs are related to quantum field theory. Thus I designed these notes to elevate students to reach the most advanced theoretical description of electrodynamics which is in the form of a classical field theory with a U(1) gauge group in terms of tensor calculus. This is also one of the purposes of publishing my notes into this book: to provide a concise journey to the most advanced theoretical description of electrodynamics. In addition, I have also provided detailed steps throughout so that students can follow the calculations with ease and this they can divert their time to try to understand the physical content of the calculations rather than busily trying to fill in the missing steps. This feature was quite highly appreciated by my students as they felt that they have the “spare time”, given the tight duration of a 3-month semester, to think about the purpose and implications of the calculations done in the lecture notes. I hope undergraduate students can start reading this book right after your year-2 Electromagnetism course. This book will then serve as an introduction to tensor calculus and elevate your knowledge of electrodynamics to the level of a classical abelian gauge theory. This will prepare you to learn quantum field theory before your FYP. Finally, I would like to declare that all the content here in this book is not original. My writing has been inspired by many of the popular and classic textbooks on electrodynamics for instance [4], [6], [5], [3] and [7].
