From the reviews: "A marvelous book, abundantly illustrated. It contains many applications ... all with an underlying geometric flavor. ... What is immediately striking at first glance is the luxury of this publication: thick paper with hundreds of colorful glossy pictures and graphs. If you love books and geometry, this is one to fall in love with. ... This picture book is more than just a coffee-table book ... of a math department, because it contains not only many pictures, but also gives theorems and proofs(!)." (A. Bultheel, The European Mathematical Society, February, 2013)
