14 planned topics in this collection
Explore a light-clock model
Guide readers through a model activity connecting geometry and elapsed time while distinguishing simulation from direct experimental evidence.
Predict an interference pattern
Introduce a guided use of the existing interference laboratory with predictions made before changing phase or coherence.
Test how much memory a record needs
Use a small state-transition example to compare present appearance with future predictive sufficiency.
Compare competing clock laws
Design a conceptual comparison in which calibration data and subsequent tests have clearly separated roles.
Inspect linked atomic spectral predictions
Guide readers through the spectroscopy application, focusing on shared parameters and independent observable comparisons.
Test a geometric construction
Use the existing geometry application to examine distances, readout collisions, and what the construction leaves undetermined.
Investigate a gauge loop
Introduce the loop simulation through observable comparisons and the distinction between frame choice and invariant content.
What a null result can establish
Explain how an expected effect, uncertainty model, and detection threshold determine the interpretation of a missing signal.
How sensitive is a prediction?
Show how varying assumptions or parameters reveals which parts of a model control an observable result.
Fit a model then test it
Use the existing comparison workbench to separate parameter fitting from evaluation on withheld observations.
Reproduce one figure from a paper
Plan an exercise with explicit inputs, code, expected output, and a documented link to the source result.
Design a useful counterexample
Show how to test a claimed implication by keeping its premises while changing the proposed conclusion.
Prepare a reproducibility note
Describe a concise report of inputs, procedures, outcomes, and discrepancies that another reader can independently inspect.
