There are Nobel Prizes in physics (some of them in my past field of research), which are being questioned in corridors. I agree that some choices of the winners seem to have more to do with affiliations, power and politics than the actual contribution to the field, but some of those gossips sound just malicious and resentful.
I have nothing against supporting women in science (where sexism in different forms is strong), even if I've seen that it sometimes creates a pathology. The support should go to women equally talented as men, but with their future chances to develop reduced by external factors (psychological - related to work in a sexist, male-dominated environment, carrying for children and family, etc.) and not to women who pretend that their contribution to science would be more significant was it not impeded by those factors (which sometimes happens and has a degrading effect on the image of women in science and science itself).
She certainly was a talented mathematician, but there seem to be more prominent names in the field and some people claim that the award should have gone to them. Maybe someone from the field has an opinion?
