Below are several short abstracts of recently published articles.

**Non-western**

** **Diamantopoulos, John; and Woodburn, Cynthia. Maya Geometry in the Classroom. *Loci: Convergence* (August 2013), 5 pp., electronic only. The authors show how classic Maya people may have used knotted ropes to form desired geometric shapes in art and architecture.

**Renaissance**

Branson, William B. Solving the Cubic with Cardano. *Loci: Convergence* (September 2013), 8 pp., electronic only. The author shows how, in order to solve the cubic, Cardano relied on both classical Greek geometric and *abbaco* traditions, and he illustrates Cardano’s geometric thinking with modern manipulatives.

**18th Century**

Wardhaugh, Benjamin. Learning Geometry in Georgian England. *Loci: Convergence* (August 2012), 6 pp., electronic only. A comparison of the geometry found in two 18th century copybooks written with two different purposes, mental acumen and practical application. DOI:10.4169/loci003930

**18th and 19th Centuries**

Wessman-Enzinger, Nicole M. An Investigation of Subtraction Algorithms from the 18th and 19th Centuries. *Loci: Convergence* (January 2014), 9 pp., electronic only. This survey of subtraction algorithms used in North America includes both handwritten “cyphering books” and printed arithmetic books.

**19th Century**

Del Latto, Anthony J.; and Petrilli, Salvatore J., Jr. Robert Murphy: Mathematician and Physicist. *Loci: Convergence* (September 2013), 8 pp., electronic only. The authors argue that Murphy (1806-1843) showed “true genius” during his very short life, and they provide a transcription of Murphy’s first published work in 1824.

**20th Century **

Beery, Janet; and Mead, Carol. Who’s That Mathematician? Images from the Paul R. Halmos Photograph Collection. *Loci: Convergence* (January 2012 – March 2013), 60 pp., electronic only. For each of 343 photographs taken by functional analyst and mathematical expositor Halmos from 1950 to 1990, the authors identify the subjects and provide biographical information about them. DOI:10.4169/loci003801

Meyer, Walter. External Influences on U.S. Undergraduate Mathematics Curricula: 1950-2000. *Loci: Convergence* (August 2013), 8 pp., electronic only. An examination of the influence of forces outside of mathematics on such curricular changes as increased emphasis on applications and modeling, introduction of discrete mathematics courses, and calculus reform.
