Query: Jackson might be a Great Guy but . . .

this book sure isn't. The material's there, but the presentation is lacking. You can read and reread and remained confused on even the most trivial topic. There are other electromagnetism text, some are much clearer to understand.If you don't believe me, try the test. Read a section in Jackson and try to solve a problem at the end of the chapter which relates to that section. Read a section about the same topic and solve another Jackson problem pertaining to the same material. Do this several times alternating between reading Jackson first and then reading a text of your choice first. Keep a tally of how many problems you solve correctly and the time it takes. The result shouldn't surprise you, you'll probably learn better from the source of your choice. (Actually, this test is unfair. Everybody learns in different fashions. Of course, you'll learn better from the author of your choice! And if Jackson is the author of your choice, god help you.)
