Definition

Meaning

A surname of Hungarian origin; refers specifically to Theodore von Karman, a Hungarian-American engineer and physicist.

Primarily used as a proper noun in technical and scientific contexts to denote concepts and constants named after Theodore von Karman, such as the Karman vortex street, Karman-Tsien rule, or the von Karman constant.

Linguistics

Semantic Notes

Almost exclusively used as a proper noun in compound scientific terms. Rarely used in isolation without 'effect', 'constant', 'street', etc.

Memory Aids

Mnemonic

Think: 'VON' (the German preposition) + 'CAR' + 'MAN' – a man whose work affects how cars (and planes) move through air.

Watch out

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.
