This booklet presents a entire learn of the symmetry and geometry of crystals and molecules, ranging from first ideas. The pre-knowledge assumed is arithmetic and actual technological know-how to approximately A-level; extra mathematical subject matters are mentioned in appendices. it's copiously illustrated, together with many stereoviews, with directions either for stereoviewing and for developing a stereoviewer. difficulties for every bankruptcy are supplied, with absolutely labored instructional ideas. a set of linked laptop courses has been devised and put online, for aiding either the examine of the textual content and the suggestions of the issues. The courses are simply performed, and directions are supplied within the textual content and at the display screen display. The applicability of symmetry in daily life in addition to in technological know-how is under pressure. element teams and house teams are first mentioned and derived in a semi-analytical demeanour, and later through use of team conception. the fundamental ideas of crew conception are mentioned, including functions to symmetry, chemical bonding and elements of vibrations of molecules and crystals. The e-book is addressed to these learning the actual sciences and assembly the topic for the 1st time, and it brings the reader to a degree of appreciation for the definitive works produced by way of the overseas Union of Crystallography, similar to the overseas Tables for X-ray Crystallography, Vol 1 (1965) and the overseas Tables for Crystallography, Vol A (2006).
