Challenge 1 of 3
Foil-stack clearance
A single foil sheet is too thin for this gauge. Build a stack and correct the gauge’s zero offset.
Challenge cleared. Continue to unlock the next experiment.Handles also support arrow keys; the sliders offer the same controls.
Report a sheet thickness in the reference band with a resolution bound no larger than ±0.010 mm.

Test 1Restoring your saved experiment…
3 stars on your first test; 2 within three; 1 after that. A first clear earns 100 XP plus 10 per star. Better star records earn the difference; repeating a record earns no extra XP.
Your experiment is ready.
Correct a zero offset and choose enough repeated lengths or periods to meet both an accuracy band and a resolution limit.

The physics behind the game
Correct a zero offset and choose enough repeated lengths or periods to meet both an accuracy band and a resolution limit.
x = (reading − zero offset) / N; resolution bound = Δreading / N
Model assumptions. Items and periods are identical in this model. The displayed ± value is a conservative instrument-resolution bound for the total reading, divided by N; it is not a statistical standard error. Repeating does not remove an uncorrected zero offset.
