Start with a single shape. Repeat it in some way--translation,
reflection over a line, rotation around a point--and you have created
symmetry.
Symmetry is a fundamental phenomenon in art, science, and nature that
has been captured, described, and analyzed using mathematical concepts
for a long time. Inspired by the geometric intuition of Bill Thurston
and empowered by his own analytical skills, John Conway, with his
coauthors, has developed a comprehensive mathematical theory of symmetry
that allows the description and classification of symmetries in numerous
geometric environments.
This richly and compellingly illustrated book addresses the
phenomenological, analytical, and mathematical aspects of symmetry on
three levels that build on one another and will speak to interested lay
people, artists, working mathematicians, and researchers.
