Domain-specific¶
- Wagon-Wheel Effect
- The wagon-wheel effect is the visual phenomenon in which a spoked wheel rotating rapidly appears to slow, stop, or reverse direction — named for the appearance of stagecoach wheels in early Western films
This sourceEstablishes the phenomenon — wheels appearing to rotate backward in the movies and under stroboscopic presentation, and also under continuous light — but not the stagecoach-Western provenance of the name.

Mechanisms¶
- Fixed-Interval Sampling Schedule
- Its central failure is temporal aliasing — a fast periodic or bursty process observed on a coarse fixed grid can disappear entirely or masquerade as a slower pattern, the same stroboscopic illusion that makes a filmed wagon wheel appear to spin backwards.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
