Mark Bollman's paper, "Numerical approximation to pi using parabolic segments", was published in the Journal of Concrete and Applicable Mathematics. This paper represents joint work with George Grossman of Central Michigan University and is an extension of the work of Archimedes (c. 287 BCE- c. 212 BCE), who used inscribed and circumscribed polygons to approximate pi. The official citation is J. Conc. Appl. Math., 10 (2), p. 236--245, 2010.
