This lovely book is an excellent introductory text in vector calculus.  It is suitable for students because it is written in informal but alluring and almost strict and severe manner, and because it covers all for them indispensable theory together with its applications. Each chapter is provided with a excellent examples and problems at the end of it. Solutions to almost all of problems are given at the end of the book. Greatest worth of the book is, in my opinion, that it gives a thorough physical background of the theory. I think that mathematicians, physicists and engineers can really benefit from this text by finding a lot of interesting for them inside it, like Maxwell's equations and much more.
