This is an amazing training video for the Navy from the 1950’s on their mechanical computer used to control guns on the ship. I learned a lot about how certain mechanisms work and it also helped me to better understand what computing essentially is.
I was also using Khan Academy for the first time in a little while, and found these awesome videos about how some common household electronics work. Like this one:
I’m also reading my grandfather’s memoir! So far I’ve learned about what the Swiss German border was like during WWII and about my family. I learned that his hime town of Grenzach had its own distinct dialect until the large chemical companies brought in a ton of workers from elsewhere. I also learned that the train used to go through Switzerland from one part of Germany to another. It would not stop there when the war was going and the borders were locked down. Guards were on the lookout for jumpers. As a boy, my grandfather saw a young man, risking death, jump from the fast moving train in Switzerland and escape. It is a great read so far and very interesting. Hi Grandpa! Thanks for writing a memoir!
