@erou sorry to burst your bubble, but there does not seem to be a consensus for this, and may be more anecdotal rather than factual:

@sojournTime Well, I guess it is hard to know for sure what she did exactly. But the article on Wikipedia seems to offer some views on the subject (footnotes 37 to 44).
But thanks for the reminder that the story is not that clear :)
@erou though this doesn't detract from the fact that many women have contributed to science and mathematics like Marie Gaetana Agnesi, Ada Lovelace, Emmy Noether, Marie Curie, and Grace Hopper to name a few:
