@stevemould: Ever find yourself just needing to know how things work? Before electronic calculators, there were mechanical ones, like the Curta, the only handheld mechanical calculator ever made! I showed this off at the last Festival of the Spoken Nerd show, and there’s plenty more where that came from. Join us at the Royal Institution, London, on March 2nd for more sciencey nerdy demos. Bring your nerdiest friends, they’ll love it. Link in bio #FestivalOfTheSpokenNerd #CurtaCalculator #RoyalInstitution #stevemould

I think I saw one of these in a pawn shop in Oregon a couple years ago. I fiddled with it and thought it was neat but didn’t know what it was. Now I’m kicking myself! It was in good shape for $45!!

As someone who studied computer science this is really interesting. I learnt 2s compliment, didn't think of 9s compliment

I love how you explained every single step with great detail and I still did not know what the hell was going on for the entirety of the video
