Who's That Mathematician? Images from the Paul R. Halmos Photograph Collection, by Janet Beery and Carol Mead
The well-known mathematician took most of these 343 photos of mathematicians from the 1950s through the 1980s. We welcome you to provide additional information about the photo subjects, including fond memories and interesting stories. This article was an expanding feature throughout 2012 and through March of 2013, with new photos added every week.

Maya Geometry in the Classroom, by John Diamantopoulos and Cynthia Woodburn
Classic Maya people probably used knotted ropes to form desired geometric shapes in art and architecture: here's how!
To what extent did forces outside of mathematics influence such curricular changes as increased emphasis on applications and modeling, discrete mathematics, and calculus reform?
Robert Murphy: Mathematician and Physicist, by Anthony J. Del Latto and Salvatore J. Petrilli, Jr.
The authors show that Murphy (1806-1843) displayed “true genius” in a very short life and they provide a transcription of Murphy’s first published work in 1824.
Solving the Cubic with Cardano, by William B. Branson
The author shows how, in order to solve the cubic, Cardano relied on both classical Greek geometric and abbaco traditions. He illustrates Cardano's geometric thinking with modern manipulatives.
