This book provides a clear introduction to the issues that are essential for students in a wide range of scientific disciplines, but otherwise are covered only in specialized texts and mathematically detailed. Shows how the crystal structures can be built from simple ideas of atomic packing and coordination, develops the concepts of crystal symmetry, point groups and spaces through two-dimensional examples of patterns, explains the concept of Reticular reciprocity in simple terms and show its importance in the understanding of light, X ray and electron diffraction.

practical examples of applications of these techniques and also the importance of diffraction performance optical instruments are described. The book is also of value to the general reader, as shown, for biographical and historical references, how developed the subject and thus indicates some of the excitement of scientific discovery
