Top Secret Rosies

I tutor my niece in senior physics. A few weeks ago I wanted to show her the practical application of physics. I knew that during WW II there were hundreds of "human calculators" turning out ballistics tables for bombs and artillery shells and I was looking for a sample to show here how the Equations of Motion were used. And then I got an email from the WW II Museum. It seems someone has made a documentary about the women mathematicians who sat behind mechanical calculators for hours churning out ballistics tables. I can't embed the trailer, but you can find it here.
