Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'von' (a German noble particle) into Russian. It is part of the fixed name. Say 'эффект фон Кармана', not 'эффект Кармана'.
- Do not confuse with the unrelated word 'karma'.
Common Mistakes
- Incorrect capitalization: 'Von Karman' or 'von karman'. Correct: 'von Karman'.
- Omitting 'von': referring simply to 'Karman constant'. While sometimes used, the full form is standard.
