SIMIODE OnLine Text
Differential Equations: A Toolbox For Modeling The World

Kurt Bryan, Rose-Hulman Institute of Technology, Terre Haute IN USA, is authoring a SIMIODE online, hyperlinked text, Differential Equations: A Toolbox For Modeling The World,  in SIMIODE which will bind rich modeling resources so faculty can teach a complete differential equations course motivated by modeling and students can save a bundle of money! Dr. Bryan (with co-author Tanya Leise, Amherst College, Amherst MA USA) has authored several pieces in SIAM Reviews over the years. For example they explain The $25,000,000,000 Eigenvector: The Linear Algebra behind Google. Dr. Bryan has also authored (with Allen Broughton, Rose-Hulman Institute of Technology) Discrete Fourier Analysis and Wavelets - Applications to Signal and Image Processing.

The SIMIODE online text will have the traditional topics flow, but will be rooted throughout in modeling as a motivation and teaching approach with links to SIMIODE and other resources.  By 15 May 2021 there will be full complete version online for consideration in Fall 2021 use in your course.

You can get access to the preliminary version by writing to Director@simiode.org with your personal request. After 15 May 2021 you can get access to the ready to use published version in the same manner. Visit to see the Table of Contents.

So for now, know there will be a very affordable and solid text - for $45 US - that will motivate learning differential equations through modeling. The text will include traditional exercises and solutions in addition to rich motivating modeling activities from SIMIODE and elsewhere. All other resources in SIMIODE will remain FREE as Open Educational Resources (OER) while this text will bring together the modeling approach SIMIODE supports, weaving together and binding the freely available SIMIODE resources. In addition, modeling activities, exercises, and projects, along with rich sections on dimensional analysis, parameter estimation and system identification, and control theory, for example, will point the way to applications for students while motivating them to see the value and context of differential equations in operation.

New Modeling Scenarios in SIMIODE

Mary Vanderschoot, Wheaton College, Wheaton IL USA published her Modeling Scenario, Modeling a Grazing System, in which she says, "One of the most well-known mathematical models in ecology is the Lotka-Volterra predator-prey system of differential equations. Initially, this model was used to analyze interactions between two animal populations. But ecologists discovered that it could also be applied to plant (`prey') and herbivore (`predator') interactions. A grazing system (such as sheep in a pasture) is a special type of plant-herbivore system in which the herbivore population is controlled by humans. Because the number of herbivores does not change, the model consists of a single differential equation for the vegetation."

Further, PROF Vendershoot, also published her enriched Modeling Scenario, Plants Versus Herbivores. She says in her abstract, "In a recent study of plants and herbivores on an island in the North Sea, ecologists made a surprising observation: Instead of more vegetation resulting in more grazers, more vegetation resulted in fewer grazers." Sounds interesting!

Publish Your Class Efforts in SIMIODE

If you are teaching differential equations of some sort you have probably written and assigned projects. Consider publishing your materials online in SIMIODE using our peer reviewed, double blind referee system. More and more colleagues are accepting our invitation for sharing and publishing their teaching materials in SIMIODE for others to enjoy. Join in with us!

SIMIODE maintains a double-blind, peer-reviewed process for quality online publication of Modeling Scenarios and Technique Narratives. However, we encourage authors to submit their ideas at any stage of development and/or class projects for immediate feedback of a less formal nature. We will render constructive support and encouragement as well as technical feedback. In the past the SIMIODE Director, Brian Winkel, as Founding Editor of the journal PRIMUS, found this to be a very good way to foster confidence, help prospective authors contribute to the broader community, and get their ideas published.  Please drop us a note with your ideas and/or materials to Director@simiode.org. We will respond quickly!

You can see how to submit your materials here. What you do is important to your students, but it is also worthy of sharing with colleagues and their students. Step up and write up your projects for SIMIODE. You will have an online refereed publication at SIMIODE. You will be pleased to know others are using your ideas, building on your success, and enjoying what you share with your students. So, what are you waiting for? Just do it!

One purpose of SIMIODE is to offer colleagues solid, refereed teaching material on which they can base a modeling first course in differential equations. Thus publishing your new ideas and activities for students is a main objective of SIMIODE so others can see your fine work and engage their own students in similar manner. However, it is reasonable to ask yourself, "Why should I prepare, submit, and publish in SIMIODE?" Here we give you many good reasons to publish in SIMIODE. Check them out and see that many fit you. Then join us by sending us your efforts.
