2、lph J. Magyar.1physics problem is wording the problem vaguely enough so that no one can figure out what your talking about.? First try to solve the problem without even reading the text. More often than not, you can solv

3、e the problem with just algebra or only a superficial knowledge of the topic. It’s unfortunate, but a great deal of physics problems tend to be just turning the crank. Do remember to go back and actually read the text th

4、ough. Solving physics problems is meaningless if you don’t try to understand the basic science about what is going on.? If you are allowed, compare your results and methods with other stu- dents. This is helpful. People

5、are quick to tear apart weak arguments and thereby help you strengthen your own understanding of the physics. Also, if you are like me, you are a king of stupid algebraic mistakes. If ten people have one result, and you

6、have another, there’s a good like- lihood that you made an algebraic mistake. Find it. If it’s not there, try to find what the other people could have done wrong. Maybe, you are both correct!? Check journal citations. Wh

7、en Jackson cites a journal, find the refer- ence, and read it. Sometimes, the problem is solved in the reference, but always, the references provide vital insight into the science behind the equations.A note about units,

8、 notation, and diction is in order. I prefer SI units and will use these units whenever possible. However, in some cases, the use of Jacksonian units is inevitable, and I will switch without warning, but of course, I pla

9、n to maintain consistency within any particular problem. I will set c = 1 and ¯ h = 1 when it makes life easier; hopefully, I will inform the reader when this happens. I have tried, but failed, to be regular with my

10、 symbols. In each case, the meaning of various letters should be obvious, or else if I remember, I will define new symbols. I try to avoid the clumsy d3? x symbols for volume elements and the d2? x symbols for area eleme

11、nts; instead, I use dV and dA. Also, I will use ? x,? y, and ? z instead of ? i,? j, and ? k. The only times I will use ijk’s will be for indices. Please, feel free to contact me, rmagyar@eden.rutgers.edu, about any typo
