Just a great collection of motivational mathematics quotes, posted in 2024. Why did I not know about these before? But you can find and enjoy them now. Take care.

Motivational quotes are a great way to get excited, get moving, and share your passion. We love math, so our collection focuses on powerful math quotes.

We are pleased to announce the publication, by the American Mathematical Society, of Teaching Differential Equations with Modeling-First Scenarios. Written by Brian Winkel, the founder of SIMIODE (Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations), this book provides a collection of resources that facilitate a modeling-first approach to teaching differential equations. Each of the forty-three chapters presents a unique, realistic, and classroom-tested modeling scenario, covering diverse topics such as chemical kinetics, stochastic processes, circuit tuning, and stadium design.
The modules are standalone, meaning they can easily be introduced into an instructor’s differential equations course. Through these activities, students discover how differential equations arise naturally and appreciate their importance.

The book is written as a conversation between two colleagues, discussing the underlying modeling scenarios. They share their methods, pedagogical approaches, and experiences, answering questions which arise about how to teach modeling.

These dialogs also provide scaffolding, advice, and reflections for faculty considering introducing active-learning opportunities into their classes. Teaching Differential Equations with Modeling-First Scenarios offers a friendly introduction to modeling activities in the undergraduate classroom, with only prior exposure to derivatives being required. For the instructor, a desire to engender an attitude of experimentation, investigation, and excitement in their students is the most important prerequisite.

Math doesn’t have to start with formulas.
SIMIODE’s free modeling scenarios flip the script by starting with real-world problems, then building the math from there.
Perfect for students, educators, and anyone who wants math to actually click.

SIMIODE – Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations (https://qubeshub.org/community/groups/simiode) announces its annual online, international conference EXPO 2026, devoted to practical activities for the classroom to build modeling-first differential equations courses.

SIMIODE EXPO 2026, 13-14 February 2026, Noon to 9:00 PM EST USA, will feature parallel sessions and breakout rooms for faculty to share their approaches and materials for participants to come away with clear and valuable activities for their own classroom. Early registration is $75US and registrants can bring a colleague FREE to share the good news of effective uses of modeling. Sessions will focus on immediate use activities participants can bring to their classroom. Individual collegial meetings and conversations are supported by the conference platform, so participants can meet new colleagues and exchange ideas.

See https://qubeshub.org/community/groups/simiode/expo for complete details. SIMIODE is a non-profit community of practice devoted to supporting a modeling-first approach to motivating and teaching differential equations which has received NSF funding.

Consider our SIMIODE textbook, Differential Equations: A Toolbox for Modeling the World, by Kurt Bryan, now in paperback and online HTML version - the latter with many SAGE Math interactive sections. Hundreds of students are learning their differential equations through this modeling-first approach. See complete details at https://qubeshub.org/community/groups/simiode/textbook

SIMIODE Challenge Using Differential Equations Modeling
SCUDEM X 2025 -- 18 October 2025 - 11 November 2025

See complete details at SCUDEM (https://qubeshub.org/community/groups/scudem) with all previous problems posed, student results, and Outstanding team videos from all past SCUDEM Events.

See complete rules and rubric for SCUDEM.

FREE MatLab license for registered teams/coaches and tutorial support from MathWorks.

Highlights
• Registration open for three student member teams from undergraduates and high schools.
• Three-member student teams (high school, home school, and undergraduate) are to work on one of three model choices, for example from last year, in engineering/physics, chemistry/life sciences, or social sciences/humanities and produce a ten-minute video of their modeling efforts.
• In recent years each team has received on average 8 judge's comment sets - terrific growth and learning feedback.
• SCUDEM judges from around the world are committed to being fair and constructive in their judging and feedback.
• Awards are Outstanding, Meritorious, Successful with Outstanding Award team videos published at SIMIODE YouTube Channel.

We are in need of volunteer Judges (see https://qubeshub.org/community/groups/scudem/judge-info) and know you will find it rewarding to see what these talented students produce.

And now for something completely different from SIMIODE. . . . in a keynote presentation at SIMIODE EXPO 2022 Craig Bauer, Mathematics, York College of Pennsylvania, York PA USA, Editor Cryptologia tells us, "Why I Love Cryptology (and Why You Will Too)" https://www.youtube.com/watch?v=9Ny2PvrKjB0&list=PLHUyzRr_S0Tuu8vQujEcB4meU-H7T6mp-&index=4 /

Indeed, cryptology intersects many other fascinating disciplines, such as history, art, music, crime, and the paranormal to an extent that is greater than any other mathematical discipline. It also has extremely strong connections with engineering, computer science, and most recently quantum mechanics.

The overlap between cryptology and mathematics in general is nearly complete. In the talk, I will rapidly share examples of a great many of these intersections as justifications for my claim that you will love immersing yourself in cryptology. For those already familiar with the subject, I promise there will be several examples that you have likely missed and will greatly enjoy.

Learn about this exciting field which is filled with rich materials for motivating the study of serious mathematics with serious consequences.

Modeling Scenarios for Calculus Instruction – From SIMIODE EXPO 2023 Conference Videos

Jennie D’Ambroise, SUNY Old Westbury, Old Westbury NY USA, in her talk at SIMIODE EXPO 2023, Adapting SIMIODE Modeling Scenarios for Calculus - see https://youtu.be/25wBefDW71Y, reviews examples of modeling projects that were adapted from existing SIMIODE Modeling Scenarios, e.g., Spread of Oil Slick (https://qubeshub.org/community/groups/simiode/publications?id=3309&v=1) .

The adapted lab projects are designed for Calculus I students with virtually no additional preparatory lecture needed aside from standard Calculus I material. The projects take a modeling first approach in order to help students discover the basics of differential equations through modeling. Each project includes basic components of a typical differential equations lecture that the students see for the first time within the modeling project.

This talk focuses on the pedagogical approach of adapting existing SIMIODE scenarios, with mindfulness towards an unforgiving required syllabus schedule for your Calculus class. As this approach is evolving, participants will have the opportunity to give feedback on the presenter's new ideas for the Spring semester.

SIMIODE – Systemic Initiative for Modeling Investigations with Differential Equations is a FREE Community of Practice in support of a modeling first approach to teaching differential equations, wherever that might occur – calculus, differential equations, or modeling courses.

L*D Pharmacokinetics Modeling as an Intro to Compartment Models in Teaching Differential Equations

The most downloaded SIMIODE Modeling Scenario for teaching modeling-first differential equations is a compartment mixing problem (and a Spanish version as well!), but it is not about the salt – it is about L*D. See https://qubeshub.org/community/groups/simiode/publications?id=3333&v=2 . This modeling activity demonstrates with real data from patient blood draws how one can determine the amount of a drug in the body tissues just from sampling blood over time.

This widely used pharmacokinetic model discourse is but one of hundreds of FREE Modeling Scenarios available at SIMIODE – Systemic Initiative for Modeling Investigations & Opportunities with Differential Equations. Visit us at https://qubeshub.org/community/groups/simiode .

Come see for yourself and bring modeling to your coursework for your students. Students get motivated, enjoy the application, and develop a healthy sense of inquiry as to applications of mathematics.
