The movie “Hidden Figures” comes to theaters this month. The film looks at the lives of a group of African American women who worked for NASA as “human computers” - the brains behind the calculations necessary for human space flight. In this Short Take, Brian talked to Margot Lee Shetterly (the author of the book the movie is based on) about the work the women did on projects Mercury and Apollo and the impact they had on the 20th century.
