Inquiring into the nature of scientific discovery, this text focuses on six personalities and six scientific fields: Johannes Kepler and modelling, Buckminster Fuller and molecules, Linus Pauling and helices of biological systems, A. Kitaiigorodskii and packing of shapes, D.J. Bernal and quasicrystals, and Pierre Curie and symmetry breaking. Excerpts from conversations with 40 leading scientists, including 17 Nobel laureates, enliven the discussion. Culture and science blend inseparably in this book and natural curiosity is the only prerequisite to enjoy it. The authors created this book for the interested general public.
