This woman spoke at my graduation...enjoyable speaker, and very talented too...
All this stuff about women in the sciences is complete and total BS. If women want to go into the sciences, there is not only nothing to stop them, there are scads of benefits to encourage them.
This "Women are discouraged from entering the sciences" is the Via Dolorosa of the feminist movement...or at least just one of them.
I am sick and tired of seeing it. Sciences is one of the few areas where you can still be judged on your ability, and faking it is difficult in some aspects and impossible in others. If you can't do the math, you can't do it. If you can't code...you can't do it.
