While I agree that the question is not suitable for MO, it could be suggested to the OP to repost it at one of the History sites on SE. — მამუკა ჯიბლაძე 12 hours ago
@jasmine I doubt you'd be interested (after all, your question has already been answered) - but since posting on History of Science and Mathematics was suggested in the comments, I thought it was worth at least mentioning it to you.
