用法筆記

In physics writing, McDonald is usually referred to by his full name (Arthur McDonald) on first mention and by the surname alone thereafter. Do not confuse him with the unrelated fast-food brand McDonald's.

常見錯誤

❌McDonald's research' (with possessive apostrophe-S, implying the fast-food chain).
✅McDonald's research' is actually correct for the physicist
💡the surname McDonald already ends in -d, so the possessive is McDonald's. But avoid contexts that could confuse the physicist with the restaurant brand.
