The geological and materials sciences have a number of common interests and interfaces, according to a report recently issued by the National Academy Press. Entitled Fostering Increased Cooperation Between the Geological and Material Sciences, the report provides a relatively low-key comparison of areas of common ground between the two sciences; it identifies no major issues of disagreement and thus has no axes to grind. Instead, the report is a short, soft-sell discussion of the burgeoning revolutions taking place in the more applied sectors of the geological and condensed matter or solid-state sciences. The material sciences are receiving a wealth of experience with highly complex mineralogical and geological materials and advances in the applications of analytical techniques that had been originated by solid-state scientists for the study of metals and single compounds. In turn, the earth sciences are receiving new techniques and theories from the material sciences.
