This is a quirk of HN posting policy: to use the original article title.

Except when it's misleading or linkbait. That one was arguably misleading, though with the quotes not so much.

Edit: the title was "A woman wins ‘Nobel Prize of math’ for the first time". We changed the article to the more substantive simonsfoundation.org piece about Mirzakhani.

The "Nobel Prize for Math" makes the significance of this prize more obvious to the people that don't yet know about it.

I agree, but it also made me click not because it was a woman, but because it made me think a Nobel prize for math suddenly exists (didn't notice the quotes.) I was actually disappointed.
