Memoirs of a Differential Equations Junkie, Part II
By Tyre Newton

This is a continuation of the article "Memoirs of a Differential Equations Junkie," which appeared in the Summer-Fall 1994 issue of the CODEE Newsletter.

Competing Microorganisms
By S.F. Ellermeyer

The classical model for competition between microorganisms in continuous culture provides a good basis for a computer project to assist students in making the transition from scalar differential equations to systems. In this article, the author outlines a pair of projects on population dynamics for competing species.

Laboratory Exploration on a Coupled Spring-Mass-Damper System using Stella and Maple
By Bem Cayco; Barney Krinsky; Mickey McDonald

This project engages students in the exploration of a coupled spring-mass-damper system.

Boston University Differential Equations Project
By Glen R. Hall

The author describes a revision to a sophomore-level differential equations course.

Percy Possum Plunders
By Graeme Wake

The ecological balance in New Zealand was disturbed by the introduction of the possum from Australia in the 1830s for a planned fur-trade. Because there were no natural predators for these possums in the lush forests of New Zealand, their numbers increased rapidly. This project contains a model to describe this situation.

Editor's Corner: Review of Nonlinear Dynamics and Chaos
By Michael Moody

"Steven Strogatz book, 'Nonlinear Dynamics and Chaos' is a very interesting new addition to the dynamical systems text lineup. Anyone teaching a first course in dynamical systems should give it strong consideration..."
