my first formal position of employment involved working with a government IT department, specifically accounting. the number of things they did with excel was hilarious.i didn't do much work with excel in my role but i learned quite a lot about writing excel scripts at that time. funniest thing about excel spreadsheet scripting is that it seems to be something that women are particularly good at. there was a lot of women in the office i worked in. it left me with a vague impression in general that women were good bookkeepers, and later encounters with book keepers confirmed this. it's beautiful tho. not saying in all cases women are not capable of really inventing things but they sure as hell are good at operating calendars and ledgers. i cite the case of Mileva Maric, wife of Einstein, for this. i'm pretty sure what the women of yugoslavia say about her is correct: that she was the actual inventor of relativity theory. so, don't misread me by thinking that women are not capable of invention. to the contrary, i think they are very capable as a class of human in the process of invention. probably they originally invented math and calendars. the motivations for which should be clear, since the first big insight about these two topics logically would have likely emerged from those who are most subject to biological clocks. ie, fertility.
