Terminology
Inside Jokes
"Let’s just add more parameters!"
A tongue-in-cheek reference to how modelers sometimes respond to poor model fit by increasing model complexity, which can ironically reduce model interpretability.
"All models are wrong, but some are useful."
A famous quote by statistician George Box often cited humorously to acknowledge the inherent imperfections in models while recognizing their practical value.
Facts & Sayings
„Parameter sweep“
Systematically exploring a range of parameter values to understand how changes affect the model's behavior.
„Sensitivity analysis“
A process to determine how sensitive the model's outputs are to variations in input parameters.
„Model calibration“
Adjusting model parameters so that the model output closely matches experimental or observed data.
„ODEs and PDEs“
Abbreviations for Ordinary Differential Equations and Partial Differential Equations, fundamental mathematical tools used to describe dynamic systems and spatially distributed phenomena.
„Agent-based simulation“
A computational modeling approach where individual entities ('agents') are simulated to observe emergent system behaviors.
Unwritten Rules
Always justify model assumptions explicitly.
Unstated assumptions can undermine credibility; insiders expect clear articulation of why particular simplifications or parameterizations are made.
Prioritize model interpretability over sheer complexity when possible.
Elegant, transparent models are valued because they foster understanding and facilitate communication with non-experts.
Collaborate with domain specialists early and continuously.
Ongoing dialogue with experts in the modeled system ensures assumptions and data used are valid, increasing the model's relevancy.
Document simulation steps and parameter choices thoroughly.
Reproducibility is critical; poor documentation leads to mistrust and hampers peer review.

Time to basics: 2-4 weeks
1
Learn Modeling Fundamentals
2-3 hoursBasic
Summary: Study core concepts: variables, assumptions, simplification, and model types in real-world contexts.
Details: Start by building a strong foundation in the essential principles of mathematical modeling. This includes understanding what a model is, why simplifications and assumptions are necessary, and how variables are defined and related. Focus on the distinction between different model types (deterministic vs. stochastic, discrete vs. continuous) and the importance of translating real-world problems into mathematical language. Beginners often struggle with overcomplicating models or missing key assumptions; to overcome this, practice identifying the main features of simple systems (like population growth or basic physics problems) and try expressing them mathematically. Use introductory textbooks, lecture notes, or reputable educational videos to guide your study. This step is crucial because it forms the conceptual backbone for all further modeling work. Evaluate your progress by explaining modeling concepts in your own words and by critiquing simple models you encounter in textbooks or online.
2
Work Through Classic Examples
3-5 hoursBasic
Summary: Solve and analyze classic modeling problems (e.g., population growth, epidemic spread, traffic flow).
Details: Apply your foundational knowledge by working through well-known, accessible modeling problems. Choose examples like exponential population growth, the spread of infectious diseases (SIR models), or basic traffic flow. These problems are widely used in the community to illustrate modeling principles and are often the first step in hands-on engagement. Carefully follow the process: define variables, state assumptions, construct equations, and interpret results. Beginners may find it challenging to translate real-world descriptions into equations or to interpret the meaning of solutions. Overcome this by comparing your approach to worked solutions and discussing your reasoning with peers or in online forums. This step is important because it bridges theory and practice, helping you internalize the modeling process. Assess your progress by successfully completing several classic problems and being able to explain the reasoning behind each step.
3
Join Modeling Community Discussions
2-4 hoursIntermediate
Summary: Participate in beginner-friendly forums or groups to discuss models, ask questions, and share insights.
Details: Engage with the mathematical modeling community by joining online forums, discussion boards, or local study groups focused on modeling. Look for spaces that welcome beginners and encourage questions—these might be university-affiliated groups, open online communities, or social media groups dedicated to modeling. Start by reading ongoing discussions, then contribute by asking clarifying questions or sharing your attempts at classic problems. Beginners often hesitate to participate due to fear of making mistakes or not understanding jargon; overcome this by focusing on learning rather than perfection, and by seeking out threads specifically labeled for newcomers. This step is vital for building your modeling vocabulary, learning community norms, and getting feedback on your work. Measure your progress by your comfort in asking questions, your ability to follow technical discussions, and the feedback you receive from others.

Recreate a Published Model
1-2 daysIntermediate
Summary: Select a simple published model, reconstruct it step-by-step, and compare your results to the original.
Details: Choose a peer-reviewed paper or reputable report featuring a straightforward mathematical model (such as a basic ecological or epidemiological model). Carefully read the methodology, extract the equations and assumptions, and attempt to rebuild the model from scratch—either by hand or using basic computational tools (like spreadsheets or simple coding environments). Beginners may struggle with interpreting technical language or missing implicit steps in the original work. To overcome this, break the process into small parts, seek clarification in community forums, and use supplementary resources to fill knowledge gaps. This exercise is crucial for understanding how real-world modeling is documented and validated, and for learning how to critically read and reproduce scientific work. Evaluate your progress by successfully replicating the model's results and identifying any discrepancies or insights gained during the process.
5
Present and Critique a Model
1-2 daysIntermediate
Summary: Prepare a short presentation or write-up explaining a model, then seek feedback from peers or online groups.
Details: Take a model you have studied or recreated and prepare a concise presentation or written summary explaining its purpose, assumptions, structure, and results. Share this with a peer group, online community, or mentor, explicitly inviting critique and questions. Focus on clarity, accuracy, and transparency about limitations. Beginners often find it difficult to anticipate questions or to accept constructive criticism; to address this, frame feedback as a learning opportunity and ask for specific suggestions. This step is essential for developing communication skills, a core value in the modeling community, and for learning how to defend and refine your work. Progress is measured by your ability to clearly explain your model, respond to questions, and incorporate feedback into future work.
