Homework Solutions for Griffiths

1. Introduction

An introduction is very necessary to what this project will be. I would like to take this chance to give an account of how solutions are done for a typical problem and how the answer can be presented. The main standard should be observed: any student who read the solutions should understand clearly how that particular question is solved and what the answer is, so that readers should not pick up half way through and not able to understand what is going on. Sometimes relevant circuits and diagrams will be given in the solutions but I will try to present them in the way so that it is not necessary to refer to the question. This solution scheme is written in a pretty standard pattern. 3 levels of headings should be observed throughout the project. Give a bit thought and you will see how clear is the project classified with proper levels of headings. Also some new commands appeared here and that will be used to help organizing the table of content for the final output, the new commands are very straight forward and you are referred to the beginning of the project if you got any troubles of understanding the usages. Last but not the least, apology is made in advance as it looks like there are a lots but just a little of circuits and diagrams in this solution case and we know that it is quite tough of understanding sometimes without a good presentation of them. Anyway, we have to work and wish you enjoy reading it. Cheers.

2. Problem-solving strategies

Furthermore, in using the strategies mentioned above, there are a couple of questions you might want to try to answer in your working through a problem. You will not always answer each of these questions in a particular order – all of them probably joggle around your brain. The point is this: learning to solve problems is essentially a skill like any other. It can be developed if you can learn how to learn and learn how to think – and students seem to think that thinking is simply a matter of being smart. Well, it is not. When you write down a problem, be sure to list knowns and unknowns; write down the ways that you have in the problem; the vision that you can see with these ways in solving the problems – all the information, together with the ways, lead to the unknown; and so on and so on. And do not get stuck on one problem. If you have worked on it for more than a certain amount of time, and you can’t seem to get anywhere – go on to the next. Keep your mind fresh, so that you will not get trapped by the problems. Now, problem solving in physics is not so different from problem solving in a game, sport, or even a hobby. Try this, when you have worked a problem – take a break. Learn that five or ten minutes – get up, leave the books open, go out and inhale the breath of fresh air, stretch, and then come back. The human brain works best with a little bit of unknown but consistent change around it – perfusion, you know. Using homework solutions for Griffiths can benefit your study in physics. There are several great things given in this book on the strategies of using the given ways to work on the problems and other new ways, a whole ton of sample problems, the meaning of the problem itself, and why do we do the problems. This type of book mostly can prepare you for the test and exam. However, studying for science subjects, there are generally two main purposes of studying; one purpose is to help you to remember the materials that are going to be on the test. This is the main reason why most students study for the test – but homework solutions for Griffiths shows you how to study for a main purpose of the studies of a topic that is to learn and knowing, give you a better and deeper understanding of the world around us, life and to increase the area of student’s thinking. In fact, the book gives you suggestions on how to effectively study something new in your memory. By the way, as your memory works basically by having a good first trial and then having many repetitive trials. This deals with what we call short-term and long-term memories. So it may not be a bad idea for all students who tried to continue to study year to year without breaking. This way, you will turn your short-term memory about physics into a long-lasting long-term memory. But possibly one of the most important things that are mentioned in homework solutions for Griffiths is to develop the tips it gives in there about studying. Previously, the book provides many different types of ways, a whole ton of sample problems were given, and a lot of description of the meaning for practicing the problems. However, if that pieces of knowledge will not be passed down to the next generation; and if students do not take those strategies and knowledge that were given in the book to their studies, then it will be just another session on and on. In fact, learning ends for physics and every other thing in the world is everlasting. We can see that the development of the knowledge seemingly will never come to an end. This book provides teach and many new and interesting ways for working on physics problems were given and also a lot of new problems for us to try. However, the strategies and tips that the book gives, in the long-term purpose of studies – is really what we want.

3. Detailed solutions for selected problems

The main focus of the book is the detailed solutions provided for a selection of problems. They are presented chapter by chapter. The first chapter is “Vector Analysis” and it starts by listing the problems of the chapter and the page that they are. It is easy to find the problem you want to solve instead of looking through the index of the Griffith book. Then, it presents the detailed solutions. For example, for problem 1, instead of simply telling you the answer, the book guides you through the whole process of solving that specific problem by stating the knowns, what the questions require, and each step of the transition. That is very helpful because it shows how a problem can be solved step by step. And even more exciting, when I was reading the chapter about “Electrostatics”, I found that the knowledge and the method that the detailed solutions were trying to give me was actually beyond the Griffith book. It shows you the reason that if the distance is very large in comparison with the variation of the fields, the derivatives of the field can be ignored. And the book gives you a list of the conditions that the problem must satisfy so that those electrostatic equations have general solutions. These are very useful for understanding the subject better and improving your ability to solve problems. In chapter three, the detailed solutions book introduces to me that a vector field can be divided into two parts which are solenoidal vector and irrotational vector and each part of a vector field satisfies two different kinds of differential equations. I think this is very helpful to help the reader to grasp the key knowledge of the chapter. Then, we present the method of image charges, which is a quite abstract concept in electrostatics and it is so difficult to visualize how image charges would distribute in a certain problem. However, by using that method to solve problems in boundary value problem, I could see the physical meaning of the method. Such kind of experience is amazing because it tells you why we learn electrostatics. After that, the book goes through the method to solve electrostatics problems using boundary conditions, which is really cool and useful. With all these functions in the detailed solutions book, it is sure that the reader would find electrostatics much easier. Also, the book indicates that in order to get the homogeneous and isotropic magnetic media, the permeability of the media should be chrochoidal. So the detailed solutions do provide many fascinating supplementary knowledge. Well, that’s really fabulous. And when I come to the chapter about “Electric Currents”, not only do the detailed solutions analyze what would happen if a current loop exists in the electric field, but also it gives a practical ability and introduces the method of finding the electric potential so that Kirchhoff’s loop equation can be used. WOW! These are truly valuable pieces of information and I fell in love with the book.

4. Tips for effective studying

I believe it is important not to study only to pass an exam, but to understand the topics and enjoy the learning process on its own. Having a deep understanding of our subjects will help us to develop our skills and apply the concepts we learn in a variety of situations in our future career. I remember how overwhelmed I was when I first studied the Griffiths and how I was going to approach it. I still remember the sense of satisfaction I had when I solved the hardest question in Chapter 1. The goodwill and the enjoyment I had during the study do lead to an unforgettable, meaningful study experience. It is really unavoidable that every student has to take an examination in the end and it might seem difficult to find time to reflect and enjoy the studying process. However, I believe that as successful learners, we must look beyond the examination and think about what we want to get out of our studies. Studying effectively not only will lead us to academic success but enable us to enjoy the study with the sense of real purpose and achievement. I think our aims should be to gain valid knowledge, which will supplement the existing knowledge in our mind and place it into a systematic and logical structure so that we are capable of retrieving it as and when we need. It is really important to have thought like this – by doing so will develop the evidence of true understanding from our learning exercises. Understanding is something deeper than a range of knowledge. It involves thinking in a critical and analytical way. We are not only required to learn the knowledge but also learn how to transfer it and use it. As physics students, we learn the knowledge and also scientific techniques to investigate and deduce the physical world around us. Therefore, it is important to think about how we can eventually reach to the best capacity for studies. I believe that the main aim for every student is to study effectively so that only little time is left to be wasted. Time is gold. We pay our parents and even ourselves a lot for our studies. It will be such a pity, regret and shame if our talent and efforts are going down to drain for not having a real, full and valid exploitation of our study time.

5. Conclusion

The book “Homework Solutions for Griffiths” is a powerful tool for students. It provides a comprehensive guide to his book “Introduction to Electrodynamics,” which is used as a textbook in many universities. The book not only focuses on solving the problems introduced in “Introduction to Electrodynamics,” but also provides general and detailed methods for different types of problems in physics. It starts with an introduction. Such information is important because there are limited resources that could explain how to start doing a problem. Knowing different methods for different problems is essential to solve that problem. It includes strategies for problem solving. This part could be very helpful for students, especially when they are stuck in a problem and have no idea how to move on to the next step. This also benefits advanced studies and research work because it explains how to use theorems in practice. The main portion of the book offers worked-out solutions for selected problems in “Introduction to Electrodynamics.” I think this is remarkable work because I benefited a lot from this book. I had learned general methods to solve problems in electrodynamics and finally conquered the difficulties in that subject. A large number of problems in “Introduction to Electrodynamics” are solved in this book. Those problems are selectively picked. In other words, it focuses on the difficult and typical problems but not the easy ones. This is very important because little help could be found for hard problems in other resources like solution manuals brought from the bookstore. The majority of the solutions are relatively longer than I expected. I think this is a great merit of this book because only concise answers are provided in the solution manual of “Introduction to Electrodynamics.” By reading and practicing with the detailed solutions in this book, our ability to use mathematical tools in physics could be enhanced, such as vector calculus and vector algebra. Also, physics is not merely a study. Last but not least, the book provides tips for effective studying. This is important but rarely can be found in other academic books. We can find so many good suggestions such as “Study Regularly,” “Do Practice Problems,” etc. With those suggestions, collaborating with the materials in this book, students could be more efficient in learning physics and achieve better grades. The conclusion summarizes the key points of the book. Critical comments and improvements for the book are also given. It is structured very well and the thinking flows are clear throughout the whole book. The topics are arranged in an effective way and reading is enjoyable. It is aimed to help students studying physics from the beginning to the end. I believe our students and myself will gain a lot in different aspects by using this book. The language of the book is easy to understand but not superficial. Although I am not a native English speaker, I could understand every single word and sentence. I have to say well done to the author and thanks for this wonderful book.
