THE PENTAGON is the official journal of the Society. It is published semiannually in December and May of each year. The first issue appeared in the fall of 1941 after the concept of an official journal for Kappa Mu Epsilon was approved at the Fifth Biennial Convention April 18 and 19, 1941. The task of planning the journal and formulating its editorial policy was entrusted to Dr. C.V. Newsom who was at the University of New Mexico, Albuquerque. Dr. Newsom served as editor until his resignation in 1943. Dr. O.J. Peterson, who was then National President, said, "The publication of such a journal is probably the most significant project ever undertaken by the fraternity." This magazine was to cater to the needs of the college students of mathematics and serve as a medium through which outstanding student papers could be published. Each issue includes:
- Articles of interest to undergraduate mathematics students are included, assisting the Society in achieving its objectives. Most of the papers are written by student KME members and many have previously been presented at national or regional conventions.
- News items about various chapters and their activities, as an aid to establishing ties between the chapters, are also included. The chapter news section is edited by the National Historian, Mark Hughes, Frostburg State University.
- A problems section, edited by Pat Costello of Kentucky Alpha, is present in each issue and includes proposed problems and solved problems.
The present Editor of The Pentagon is Doug Brown of Catawba College. You may contact the Pentagon editor via the KME Leadership Contact page.
