Develops a graphical method for studying the parallel susceptibility of an antiferromagnetic material. (SL)

Provides a simple derivation of the linear least-squares equations for obtaining the best fit straight line through experimental data points. (SL)

Describes the computation of relatively complex functions such as log x and ln x with a simple four function hand held calculator. (SL)

Meterological information is used to develop a mathematical function resembling the sine function. (JT)

This is the fourth and concluding article in a series on using mathematical techniques from history to provide an interesting way for middle graders to practice math. (Editor)

Evaluation of two methods, Stimulus Manipulation and Delay Feedback Only, for teaching four mildly handicapped students (ages 9-13) to solve missing minuend problems found both methods to be effective. However, systematic differences in error rate and long-term retention were observed, favoring the Stimulus Manipulation procedure. (Author/DB)

Timing stoplights and trying to determine the best way to allocate cycle time to the two directions is discussed. The simple case and improving the model are both considered. (MNS)

Describes a simple way of obtaining a set of relative intensities of spin-spin splitting lines using Pascal's triangle rather than calculating binomial coefficients. Provides tables showing Pascal's triangle and the relative intensities of multiplets for a range of nuclear spins. (TW)

Discusses the factors affecting the behavior of a spectral function. Lists some important properties of Fourier transform (FT) pairs that are helpful when using the FT. Notes that these properties of the mathematical formulation have identical counterparts in the physical behavior of FT systems. (TW)

Problems set in the real world help students see the relevance of mathematics. Topics that provide sources of real problems are discussed, with examples: mazes, packing, and networks. (MNS)

Two relevant applications of mathematics and computer science are presented: International Standard Book Numbers (ISBN) that appear in textbooks and universal product codes that appear on grocery products. A computer program is included. (MNS)

One mathematician's view of real problems is given. Described (with some humor) are magic retail numbers, the highway bypass, the elliptical table, and the senior-class schedule. (MNS)

The relations between a cultural fund of general knowledge and knowledge-in-use were investigated by observing the arithmetical practices of ten women enrolled in the Weight Watchers program. Apparently, the precision of dieters' measurements is dependent on situation and everyday context. Often, subjects' knowledge-in-use exceeded the general…

Examples of diversions with cards that may be used to illustrate the concept of a cyclic group and structural properties of the integers modulo a prime are presented. (MNS)

Using data about companies with which children have first-hand experience (such as McDonald's or Mattel Toys) piques interest in graphing activities. How the project is developed, with group and individual activities, is described. (MNS)
