I guess the really interesting question is *Why* are the applied sciences/mechanical/IT careers associated with males. Most of the posts here say the same thing: Nerd careers appeal to males. Why? Nursing is a totally nerdy career- there is a lot to memorize, complex physical procedures, etc. Teaching is a totally nerdy career- why are there more females in teaching?
Off the cuff, I'd say that IT and the mechanical arts are more demanding of attention/reward than the traditionally 'female' careers of teaching/nursing/secretarial arts. I might even go as far as to say that instead of women shunning 'technology' careers, men are more likely to shun the 'thankless' careers I mentioned above. Maybe men seek, nay, demand appreciation and public spoils for the hard-gotten sacrifice of becoming skilled at their obscure trade.
That raises the whole question of why teachers/nurses/secretaries don't get the appreciation their jobs deserve, and thus the discussion devolves into so much posturing...
I joined the military. Not only do women get equal pay and equal positions, they don't have to work as hard to get them[1]. Still, the military is comprised mostly of men. Go figure.
