@inthehands hiya. Was only girl to take 12th grade physics in my school. Teacher told me daily: “I shouldn’t have to teach you. Girls can’t do this subject.” Govt austerity=no textbooks (late 80s.) So teacher scrounged some uni ones. You had to know calculus to work most but not all problem sets. Teacher never told us which. The school didn’t offer calculus. The boys learned at home. I’m working class; no one to learn from. Never took physics or math again. Uni prof in humanities now.
