I have hesitated in participating in this thread, mainly because this topic HAS been discussed already a number of times. See, this one, for example

First of all, let's be clear about a couple of things:
1. No one is advocating a 1:1 ratio of women to men in science/physics. In many of the issues I've read regarding women in science, I can't ever remember reading that this was the goal!
2. No one is arguing that men and women are the same! In fact, I would like to insist that, in many aspect beyond physiology, women and men SHOULD be different! This is not a bad thing, and in fact, it is a GOOD thing. If large groups of scientists from different parts of the world with different cultures, religions, social norms, etc. can work together and present various idea from different points of views, then having men and women who are different from each other is a strength! No one is trying to assimilate one into the other!
3. There aren't that many obvious, blatant discrimination anymore in many parts, and certainly, in the US and in many Western world, it is illegal to blatantly prevent a woman moving up the ladder in science just because she is a woman.
Now, having said all that, there ARE issues in the way science is done that hinders the progress and participation of women. These are not done on purpose, nor even done consciously. Since the practice of science and how it is done have been done throughout history by men, the system in place never accounts for the issues faced by women. In the link I gave above about a previous thread on this topic, there are several issues faced by women that are unique to them that aren't usually the burden of men in general.
One such example is family obligation. While this may not be that big of an issue in, say the US, women scientists in other parts of the world are faced with the social obligation of raising a family, regardless of her standing in the scientific world. A man can just pick up and go to attend a conference, a woman can't do that that easily. Still, if you read the account giving in the links in my post, you'll see that even women here in the US continue to feel that family obligation, that they do not have the same freedom as men to simply pick up and spend, say, 2 weeks at CERN during a run.
Not being able to do all these, or not being able to do these as often, can have an affect on one's scientific career. Again, these are not something that are consciously done to prevent women from going further in science. It is just part of an established system that never had to consider the needs of women before. And recognizing that is the first step in trying to remedy the situation.
I'm not in the mood to force someone into science or to shove someone in who doesn't belong. However, I also feel that it is a shame if talented people, be it men or women, don't go into science, and especially physics, just because of other extraneous circumstances. It is especially sad if they are driven away simply because we didn't recognize the barriers we unconsciously put in front of them. It is a waste of potential talent!
