Between Elementary and Advanced Mathematics II: - 2-Dimensional Surfaces

We want to show in this book how mathematics is not only logical, but can actually be highly visual, something many peoplewere not aware of, because this kind of materials has not yet made its way into school syllabus, and are optional in university education, usually not considered as important as the likes of calculus and linear algebra.

Are you aware that there are geometric objects that exist but can't be seen by us humans?
Are you aware that there exist sealed containers that can't hold anything?
Are you interested in finding a complete list of all such objects?
If you are imaginative, have mastered school mathematics, and, optionally, understand a little bit of calculus and linear algebra, this book will interest you.
