Eve Torrence

American mathematician (born 1963)

Eve Alexandra Littig Torrence (born 1963)[1] is an American mathematician, a professor emerita of mathematics at Randolph–Macon College,[2] and a former president of mathematics society Pi Mu Epsilon. She is known for her award-winning writing and books in mathematics, for her mathematical origami art,[3] and for her efforts debunking overly broad claims regarding the ubiquity of the golden ratio.[4][5]

## Education, career, and service

[edit]

Torrence was an undergraduate at Tufts University.[2][3] She completed her Ph.D. in 1991 at the University of Virginia; her dissertation, The Coordination of a Hexagonal-Barbilian Plane by a Quadratic Jordan Algebra, was supervised by John Faulkner.[6][7]

She was Claire Booth Luce assistant professor at Trinity Washington University from 1991 to 1994,[8] before joining the Randolph–Macon College faculty in 1994.[3] She earned tenure there in 1999, and became a full professor in 2008.[9] She retired in 2021,[9][10] and was given the Bruce M. Unger Award by Randolph–Macon College on the occasion of her retirement.[9]

She served as president of Pi Mu Epsilon, the US national honor society in mathematics, from 2011 to 2014.[3] The Maryland-District of Columbia-Virginia Section of the Mathematical Association of America gave her their Sister Helen Christensen Service Award in 2019.[11]

## Selected works

[edit]

Torrence won the 2007 Trevor Evans Award of the Mathematical Association of America for a paper she wrote with Adrian Rice on Dodgson condensation:[8]

Her books include:

* Torrence, Eve (2011), Cut and Assemble Icosahedra: Twelve Models in White and Color, Dover Publications

A sculpture, "Sunshine", by Torrence is displayed in a Randolph–Macon College building lobby; it depicts the compound of five tetrahedra as five interlocked aluminum shapes, inspired by an origami version of the same compound folded by Tom Hull.[10] She also won the "Best in Show" award in a 2015 juried mathematical art exhibit, for her pieces titled "Day" and "Night", mathematical origami using folded cardstock rhombi to make hyperbolic paraboloid surfaces, connected in the pattern of a rhombic dodecahedron:[3]
