Discusses the nature of Laplace transform techniques and explains an alternative to them: the Widder's real inversion. To illustrate the power of this new technique, it is applied to a difficult inversion: the problem of Landau damping. (GA)

In order to solve a functional equation, one must identify possible functions that satisfy a given equation. This paper seeks to convince the reader that students in high school could be exposed profitably to certain functional equations. Several examples of functional equations are given and discussed. (Author/MP)

Explains how the forces of tension and buoyancy are involved in the support of a loading body by a waterbed. Solves the equilibrium equations for the shape of the membrane and deals with the weight of N bodies and the fullness of the waterbed. (GA)

Explains using exponential mathematics, the effect of growth on rate of consuming energy resources. Concludes that we are running out of energy resources at a greater rate than many people think. Lists few options left such as conservation by stopping growth of consumption, recycling, and research to develop alternate sources. (GA)

A discussion of the process by which pictures are secured from distant places by use of computers is preceded by a brief explanation of the binary number system. (MN)

Programs for calculating gravity flow using a Texas Instruments SR-52 and the Programmed Manning Equation are given and discussed. (MR)

The author gives a three dimensional analog of Pascal's Triangle as an exercise in heuristic thinking and an introduction to the multinomial theorem. The analog involves finding the number of shortest routes to various rooms in a cubical apartment house. (MN)

This article describes a one-semester junior and senior level course in applied mathematical optimization for undergraduates which provides the opportunity to test models by doing numerical experiments and to learn to use computer subroutines for solving optimization problems. (MN)

Three biorhythm cycles affecting behavior are discussed and graphed by using basic mathematical operations along with simple graphing techniques. (JT)

Discover the treasure of learning activities in your daily paper. This 20-cent text has resources for teaching reading, language arts, mathematics, science, social studies, art, career education, and local history. (Editor)

An activity involving totaling bills, completing checks and check stubs, and determining bank balances is described. (JT)

The probabilities of six-card poker hands are derived and compared to those of the five-card poker hands. (JT)

The history of the development of trigonometry is outlined from 140 B.C. through the sixteenth century. (MN)

Examined is a method of teaching based on the idea of the projective application of mathematics to simplified innovative proposals and hypotheses. (Author/MA)

The authors present a computational skills laboratory exercise for ecology conscious students. (MN)
