There is a movie out--"Hidden Figures"--about how three women launched the space program; or something like that. My daughter wants to write about them for a school project. I keep suggesting my daughter write about Sophie Germain, or Emmy Noether, Daubechies or Hypatia. But my daughter insists that these three women were able to do math that men could not, and that are the reason Glenn was launched into space. (OK, if she wants to do that, OK, but now I am curious.) I am trying to figure out what thse women did, but by reading the press (which seems riddled with propganda), I am only able to assess that they did some algebraic number crunching. Am I wrong? What did they do?
