Elementary Differential Geometry

Summary: (Most) College students will love this book
Review: I am using this book for a 2 semester Differential Geometry course at my university. The school used to use Do Carmo, but apparently the book was too advanced for the undergraduate level, so this semester they decided to switch over to give this one a test and see how it worked out. This book is not bad. It is basically Do Carmo rehashed for the not so mathematically mature. In all seriousness, the book even follows almost the exact same flow as Do Carmo, the topics are just presented with less rigor. The exercises are rather tedious at the end of each chapter, and in my opinion they don't really help to enhance the subject matter.

On the other hand, if you fall in the category that most of the math majors at my university fall in (i.e. the category of people who really don't care, they just want to get an A and graduate, and don't care about mathematics), then you'll love this book. Why? Because the solution to every single problem is at the end of the book. In my opinion this is a huge flaw. It would be great if everyone were honest and everybody was genuinely interested in the learning Differential Geometry, but that isn't the case. So 90% of my class simply copies the answers out of the back of the book and hands it in to get a 100 on the homework assignments. Pretty sad if you ask me. The book is almost there. Without full solutions to every problem, this book would get 5 stars. But those students who simply turn to the back of the book 15 seconds after looking at the problem statement will learn nothing from this book, so I have to knock it down 2 stars. After all, what good is a book if it doesn't serve it's intended purpose. Perhaps some people would rate a book by "how easy is it to get an A in the class if this is the textbook", in which case they would probably rate this book 5 stars.

Differential Geometry is a hard subject. It's _supposed_ to be hard. We're not talking about taking the reciprocal of a fraction here, it's Differential Geometry. You're _supposed_ to think about these problems for a long time. So if you're a professor considering this book for a course I would recommend against it. The text is good, but the students won't learn anything from it. I've suggested to my professor that perhaps it would be good to not assign problems from the text, but rather get problems from other textbooks where students can't look at the answers.

In my opinion that is the only flaw with this book. Otherwise I think it's a great introduction, and about as elementary as you can really make the subject. If another book was too hard, then this is the one for you.

Also, if you're interested in this book for self study it's a good choice since obviously you're genuinely interested in the subject matter and won't be tempted to look at the answer at the first opportunity.

Summary: A quick introduction to differential geometry
Review: Pressley's gives you a very comprehensible and down to earth introduction to differential geometry.
By avoiding the more modern and abstract generalizations of differential geometry to more than three dimensions you really feel that you grasp what the theorems and methods are about. In this way you are able to work your way quickly through the book and avoid getting stuck and loosing interest. Another plus is that the book contains lots of examples and fully worked answers to all exercises, which makes it perfect for self-study.
The downside is that the book is not as exhuastive as you perhaps would like, when you have looked at books like O'Neills and DoCarmos ... on the other hand, you only need to spend a fraction of the time to get through Pressleys.
I definitely think that this is a much better book that Struiks classical work (by being more structured and goal oriented) and an excellent introduction to further studies in differential and Riemann geometry.
