Query: SOLID BOOK

I bought this book when i graduated from college because i was able to take diff eq but not vector calc. (i was a chem major.) i've used it for self study to gain an appreciation for the field and in fact have access to both this and penultimate edition. i have been quite satified in my ability to get an understanding of the material this way. it's not a book for wimps: you need some mathetmatical maturity, and i agree that you have to read the text straight through to get the full effect. but the diagrams make sense and are illustrative of important points. coming from a liberal arts background, i found the historical essays interesting; and they certainly could be skipped or skimmed by the hardcore reader. the introduction is thorough to the point of being overly repetitive of prerequisite material. i've only gotten through about chap 6, but the material is present in orderly and comprehensible fashion.
