Today, women make up less than one quarter of all those employed in STEM occupations in the United States. These numbers are much worse for women of color: Asian, black women and Latinas made up slightly less than 10% of working scientists and engineers in the United States in 2015. Science is supposed to be built on objectivity, and yet, most researchers agree that these bleak numbers are evidence of deep bias. Over the course of careers, small slights add up to prevent many women from achieving leadership positions in STEM fields. And sometimes, tragically, brilliant women drop out altogether. But now, the terrain is shifting. This film chronicles the groundswell of women scientists who are changing the face of science in the United States and around the world.
