At first, Landau's book starts with relativity. and it seems that almost material goes with relativity.
In purcell's book, i studied about relativity a little, but one that in landau seems more general.

I have been studied to Purcell's book.
And, this semester finished so I'm finding another book.
Professor recommanded me the Jackson's book.
Which one will be better?
