The movie, Hidden Figures, offers a very different view, about a certain number of things, from what you would expect. Usually, study of science is thought to be largely a male dominated profession even though there is a growing number of females who are interested in this field. However, this movie focuses on a female mathematician who works for NASA and played a key role in carrying out their missions. More specifically, she calculated flight trajectories for a variety of projects. I assume the title of the movie is supposed to emphasize the fact that there are people who are very important for the success of the organization but stay behind the scenes and are left unknown to the public.
