why are the only female scientists and mathematicians those who had an official career supported by a salary in the field? There are no recorded female Philosophers, Mathematicians or Scientists who did it as a hobby which is strange due to aristocratic class putting great value on female talents to perform on the piano, sing and dance. Why is it that we don't see any females succeeding in inward reflection and knowledge until the age in which these careers were official and came with monetary intensives?
