The idiom, its algebra, and vanished

Awesome story! Thanks for sharing. I will now go to the reviewers who confirm these 'proofs" actually work. Margaret, along with Ada Lovelace and Grace Hopper, was such a huge inspiration to me as a young teen. That kind of nostalgia probably isn't available to the generations below. Oh God, that reminds me of the mission to recover the awesome midi tracks on one of the better ones I've seen, if you actually want to understand in detail.
