Applied mathematics was once only associated with the natural sciences and engineering, yet over the last 50 years it has blossomed to include many fascinating subjects outside the physical sciences. Such areas include game theory, biomathematics and mathematical economy demonstrating mathematics' presence throughout everyday human activity. The AMS book publication program on applied and interdisciplinary mathematics strengthens the connections between mathematics and other disciplines, highlighting the areas where mathematics is most relevant. These publications help mathematicians understand how mathematical ideas may benefit other sciences, while offering researchers outside of
mathematics important tools to advance their profession.
