The interesting part, with the missing context put back.
Each card starts with a claim that travels well. Then it checks the wording against an authoritative source and restores the qualification most likely to vanish in a repost.
Can the Sun rise twice in one morning on Mercury?
Yes—but only from some locations, and Mercury’s orbit is part of the explanation.
Engineering 02↗Did square windows doom the first jet airliner?
The corners mattered. So did metal fatigue and a test that accidentally strengthened its own specimen.
Measurement 03↗Is the kilogram no longer defined by a metal object?
Correct. Since 2019, its definition ultimately rests on an exact value of the Planck constant.
Method 04↗Can the same fault surface get rougher in opposite directions?
Two legitimate roughness metrics can produce opposite-looking trends across scale.
How this ledger works
Candidate claims are discovered separately, then rewritten only as strongly as the cited evidence allows. Every published card names its source, states what the source supports, and includes a boundary or caveat. These are research notes for curious readers—not substitutes for the underlying source.
