The U.S. took first place in the IMO a few days ago in Hong Kong. The U.S. was also first in 2015, and this is the first time it has ever been first for 2 years in a row (in the 42 years that it has been competing). In both years the leader has been Po-Shen Loh, a math prof at Carnegie Mellon. Each member of the team of 6 got a gold medal! (Last year's team won 5 golds and 1 silver.) (Of course, it is a totally non-level playing field for countries with vastly differing populations and training resources to compete against each other. If if were up to me, this would be a strictly individual competition.) In any case, the *problems* in this year's competition are downloadable (in almost any language you can think of) at this URL: https://www.imo-official.org/problems.aspx Some of the problems look pretty interesting. —Dan
