If you happen to not be aware of a person's or subject's relevance to a thread, why even post about your personal ignorance? What does that add? What's that old Mark Twain saying?
The thread was titled, “World famous scientist”.
I’d never heard of him before. The phrase ‘world famous’ is itself world famous for being abused and in my opinion the man may well be famous in some circles but he’s not a household name like, say, Taylor Swift.
Taylor Swift *IS* world famous. This guy? Not so much.
