Develops the group operation table for a matador and a bull on a Mobius strip. It is a model for the Klein-4 group. (RS)

This article presents some easily stated but unsolved geometric problems. The three sections are entitled: Housemoving, Manholes and Fermi Surfaces" (convex figures of constant width), Angels, Pollen Grains and Misanthropes" (packing problems), and The Four-Color Conjecture and Organic Chemistry." (MM)

Reprinted are reviews of mathematics textbooks published from 1898-1920. The mathematics includes geometry, theory of equations, calculus, and differential equations. (CT)

Considers the recommendations of 929 physicists in eight different specializations for mathematics courses for physicists. Course recommendations are indicated so that advisors and students as well as interested physicists may use these ratings as relative guides in the selection of courses for degree preparation or for industrial background.…

The problem "Given three planar points, find a point such that the sum of the distances from that point to the three points is a minimum" is discussed from several points of view. A solution that uses only calculus and geometry is examined in detail. (MNS)

An alternative approach to the basic concepts of measures of central location and dispersion is described. (DT)

Philosophies of mathematics, applications of mathematics to social or humanistic areas, where knowledge is lodged, mathematical education at a higher metalevel, and the interpretive component of mathematical education are discussed. (MNS)
