A series of nine talks in which scientists talk about concepts crucial to their field of study
6: Symmetry by PROFESSOR S. TOLANSKY
Royal Holloway College, London
All of us have some general notions of what is meant by symmetry. To a scientist the concept of symmetry is probably more important than to most people, because he tends to associate it with simplicity.
