(MIT Press) The authors provide a tour of the molecular structure of invisible atomic structures. Beginning with simple structures like air and ice to more complex structures like rare earth magnets, this book uses x-ray diffraction data to provide color illustrations and essays about atomic structures. The authors also answer questions such as how diamonds ride volcanoes to the earth’s surfaces, how viruses reproduce, and why diapers smell. Kenneth S. Deffeyes is a professor of geology emeritus at Princeton University. Stephen E. Deffeyes is a freelance illustrator and designer.
