women and girls are actively discouraged from engaging in math & science by:
teachers (dont sweat it honey, you'll make a smart man very happy with those looks)
men (i dont want to be with a smarter woman because it makes me feel inferior)
women (ew who wants a dorky nerd girl, borinnnng)
you get all that in math class as a 12-year old girl and yeah you start to associate math with unhappiness
