Many of the most significant areas of mathematics have emerged from questions about extremes: the shortest path between two points on a curved surface, the fewest colors needed for a map, the fastest fall, or the shortest proof. To illuminate how mathematicians drive knowledge forward by reaching for the edges, author and mathematician Ian Stewart explores stories of superlative problems—their history, the struggles to solve them, and the uses of some of the results.

Evolutionary biologist and writer Marlene Zuk highlights the often-ignored animals that share human environments, revealing how their lives illuminate adaptation and coexistence on a crowded planet.

A quirky 18th-century international dispute over natural history quickly took on political overtones. Thomas Jefferson wanted to refute a French naturalist’s theory that all life in America was degenerate and weak, so he asked that a large dead moose be shipped to France. The theory, however, continued to have scientific, economic, and political implications for 100 years. Evolutionary biologist Lee Alan Dugatkin highlights this fascinating tale.

Art historian Sophia D’Addio surveys the history of the capital city of the region, Genoa, as one of the major maritime powers of the Italian peninsula during the medieval, Renaissance, and Baroque periods. She also celebrates its chief culinary achievement: pesto. (World Art History Certificate elective, 1/2 credit)
