A simple and logical read :)

The lack of female Einsteins is all down to numbers from New Scientist

Why are there so few female Einsteins? Many people share a belief that while women can do science, there are far fewer women than men at the very top of the science hierarchy because women just aren't as innately good at science as men. Others feel this view is wrong but cannot easily put their finger on why.

They should be able to now. There are few women at the top of science because there are so few women in science. It's simple statistics.

...

you can no longer cite the greater number of men among the most successful people as evidence of innate differences until the effects of participation rates have been allowed for," says Bilalic.

In short, it's hardly surprising that there are so few women Einsteins when there are so few male ones – and so many more men are trying.
