This outstanding textbook by a distinguished mathematical scholar introduces the differential geometry of curves and surfaces in three-dimensional Euclidean space. The subject is presented in its simplest, most essential form, but with many explanatory details, figures and examples, and in a manner that conveys the geometric significance and theoretical and practical importance of the different concepts, methods and results involved.The first chapters of the book focus on the basic concepts and facts of analytic geometry, the theory of space curves, and the foundations of the theory of surfaces, including problems closely related to the first and second fundamental forms. The treatment of the theory of surfaces makes full use of the tensor calculus.
The later chapters address geodesics, mappings of surfaces, special surfaces, and the absolute differential calculus and the displacement of Levi-Civit . Problems at the end of each section (with solutions at the end of the book) will help students meaningfully review the material presented, and familiarize themselves with the manner of reasoning in differential geometry.

Best Pillow e
Fill Material: Down Alternative, Size: Queen/Standard Size
I’ve been using this pillow for 3 months now. It is, hands down, the BEST pillow I’ve ever had. It’s soft and supportive at the same time. As I noted, I’ve been using it for 3 months and it has maintained its loft unlike some of the other types of pillow I’ve tried. Well worth the price and I highly recommend it.

Best Pillow I’ve bought in a while
Fill Material: Down Alternative, Size: King Size
Very comfy pillow. Holds up better than the last 7 I bought which went flat after a week. It also comes with extra fill which I have not had to use yet but overall very happy!

Cozy & Comfortable
Fill Material: Down Alternative, Size: Queen/Standard Size
This pillow was a big surprise! Despite the size, it is so soft & comfortable. Being able to add & subtracting filling is wonderful. It's like having a custom pillow just for me. I am a stomach sleeper. I am able to cuddle the pillow & be very comfortable. Plus it recovers it's shape.

Overall a great pillow
Fill Material: Down Alternative, Size: King Size, Fill Material: Down Alternative, Size: King Size
I slept on it last night and I do think I’ll like it. I was used to a memory foam pillow, son this will be a change. My reason for 4 stars is because the zipper barely opens and my husband and I tried everything short of ruining the pillow. In the end I had to stuff extra stuffing into a pretty small hole. Nothing seems wrong with the zipper but I saw another review said they couldn’t add more filling. If they fix that issue then I’d rate it 5. Yes it is soft but it doesn’t go flat and if you adjust and add some more under your head it doesn’t shift. I do recommend if you like a plush pillow.
