It turns out that we in physics and astronomy are not alone - the Wikipedia has a similar problem. The New York Times reports that only 13% of Wikipedia contributors are women. There are some proposals to actively encourage women to contribute, but that is exactly contrary to the idea Wikipedia espouses - namely that the best source of knowledge is one that is allowed to grow and expand naturally from a community rather than one that is mediated by some arbiter of truth. As one of the women on Wikipedia's governing board stated:
“The big problem is that the current Wikipedia community is what came about by letting things develop naturally — trying to influence it in another direction is no longer the easiest path, and requires conscious effort to change.”So while Wikipedia might not have many answers for the physics community, at least we know we're in good company.
