From the BBC article: it will take 258 years for physics and 60 years for mathematics for the gender gap to be removed, i.e., 50% by gender publishing papers. I expect it would take even longer to get 50% distribution of full professors, maybe we will never reach such a stage.
One thing that most studies don’t really seem to address is why we have a gap. Is it social or biological?
All I can say is that women I know in science are equally capable as men. Naturally, we must all do what we can to remove barriers for all people who want to enter science and mathematics.
