Isometrica: A Geometrical Introduction to Planar Crystallographic Groups
by George Baloglou
Number of pages: 473
Donald Crowe's 'repeated patterns', may certainly be viewed as one of the very first mathematical creations of humankind. They are recognized today as the poor relatives of the planar crystallographic groups. This book's goal is therefore the gradual unveiling of the structural and the mathematical that hides behind the visual and the artistic. A determined reader can read the entire book relying only on some high school mathematics.
