The simulations are educational models, not professional calculators or real-world decision systems.
Simplified models
Every model leaves out some variables, uses assumptions, and may accelerate time or rescale visuals. Read the “Model assumptions & science” section within a simulation before interpreting its results.
No professional advice
Nothing on this website is medical, engineering, environmental-safety, emergency, financial, legal, or other professional advice. Do not use a simulation for diagnosis, construction, navigation, evacuation, treatment, investment, or safety-critical decisions.
Accuracy and external sources
We aim for educational accuracy and test model behavior, but errors can occur and scientific knowledge develops. External links are provided for context; a link does not imply control or endorsement of every statement on another website.
