One of my favorite books is “Surely You’re Joking Mr. Feynman”, and in it Richard Feynman talks about how they did the calculations for the Atomic Bomb...rooms of teams of people with colored index cards that they would perform various things, stack them in a certain order, another team would pick them up, bring them to another room, and people would do more calculations.

I found it fascinating...

Reminds me of the ladies who acted as "human computers" for NASA in the movie "Hidden Figures."

Probably very much still in use then since even then, mainframe computers were probably not entrenched in many areas...what an interesting concept.
