Are there any really good resources on modelling with differential equations?

AI Thread Summary
Teaching a first course in differential equations can benefit from a focus on modeling, which serves as a strong motivator for students. However, there is a debate among educators regarding the effectiveness of modeling in teaching. Resources that provide real-world applications, rather than artificial engineering examples, are sought after to enhance student engagement. Suggested applications include the charging and discharging of capacitors, chemical kinetics, radioactive decay, and examples from heat transport and gas pressure.The Lotka-Volterra equations are highlighted as a classic example due to their complexity and visual representation. Some educators emphasize that modeling often requires extensive subject matter knowledge, particularly for complex systems like climate models, which may exceed the current understanding of students. There is a distinction made between modeling and simulation, with some educators expressing frustration over the inclusion of numerical methods in core differential equations courses, viewing it as a diversion from the fundamental concepts. Overall, the discussion underscores the importance of impactful, real-world applications and the historical context of differential equations in teaching.

I will have to teach a first course in differential equations. A good motivator might be to promulgate modelling with differential equations but I have seen some teachers have made polemic against modelling. Are there any really good resources on modelling with differential equations? I want something which will have an impact and motivate the learner. I am not really looking for artificial engineering examples but some bona fide real applications.
Also would like to bring in some history of differential equations.

Charging and discharging of a capacitor comes to mind.
Also chemical kinetics and radioactive decay.

What do you mean by modeling?

In my experience, modeling is synonymous with simulation, and was always real world applications, solved numerically.

This goes way beyond simple analytically tractible scenarios like tank concentration etc.
 
Outside of modeling trivial systems, it usually requires a lot of subject matter knowledge to actually build-up a good model. For example, to generate a climate model, i.e., identifying the right variables and putting them in the right relationship to each other, would require subject matter knowledge in climate science beyond the student (and probably the lecturer). Common practice in a course on differential equations is probably to give a few examples of differential equations which model some system. Deriving those models is really the business of another field.

I don't interpret modeling to be synonymous with simulation. I was always annoyed with teachers who added numerical schemes into core courses. Felt like a waste of my time and their expertise.
 
Sequences and series are related concepts, but they differ extremely from one another. I believe that students in integral calculus often confuse them. Part of the problem is that: Sequences are usually taught only briefly before moving on to series. The definition of a series involves two related sequences (terms and partial sums). Both have operations that take in a sequence and output a number (the limit or the sum). Both have convergence tests for convergence (monotone convergence and...
Hi all, I am in the process of adding physics to my teachable subjects, and I have a project due soon where I have been asked to improve upon a Leaving Certificate Physics experiment. The only thing is I haven't actually taught physics yet, and was wondering if any teachers could share their thoughts on the experiments and any challenges you have faced or any improvements you would like to see made to the experiments.
