Jackson's EM book
Hello everyone,
I have some confusion about Jackson's electrodynamics book.
Once upon a time, my lecturer showed me his Jackson's EM book. I think it was an old edition. It has red cover.
He admires it a lot and so do I and he always stresses that it's probably one of the best EM books, a standard EM book with rigorous math formulations and difficult practice questions too.
But when I went to book store and found a Jackson's EM book, which is certainly a new edition one, I did not find such characteristics. I think the level is about the same as Griffith's. I just get confused why the new (dark blue cover) edition of Jackson's seems to be different from the old edition. I guess the common trend is that new books tend to be 'more pragmatic' than the older versions, removing 'assumedly-excessive and unnecessary mathematical rigors', though they may include new developments, which may not be novel from basic science principle perspective, but may be more relevant and of more practical values for real and recent world applications. Does indeed this really happen to Jackson's EM book, the new version? Or did I just get the wrong impression because I hadn't even gone thru the new version book thoroughly?
Any comment would be much appreciated
regards
