Summary
[edit]
| Description |
English: Lengths of these circles in en:Ehrenfest paradox form an en:arithmetic progression, but their radii do not. That's why rotating disc geometry is not Euclidean. Moire at the outer rim is a rastering effect. Side of the disc (in yellow) is ωr=c level.
Русский: Длины светлых окружностей образуют арифметическую прогрессию, однако их радиусы растут, при увеличении линейной скорости, всё медленнее. Зелёные риски отмечают радиусы, получаемые делением длин на 2π. Муар вызван растеризацией (не хватает разрешения). Край диска (жёлтого цвета) — уровень ωr=c. |
