Most of my history / social studies classes, including AP history my senior year, focused on the United States. I think there was and is an AP World History, but my school didn’t offer it. So we learned about Pearl Harbor, and D-Day, and Nagasaki, but not much of the Euro-centric lead-up to war.
One of my social studies classes, maybe 9th grade or so, spent a period watching The Wave, which might be the closest part of my formal education to addressing OP’s question.
My microwave’s beeper only work in 10s increments. Meaning if I enter a cook time of 91 seconds, I get 91s at high power, 9s at low power, and a beep. If I listen for the power change, I have a 9 second window to open the door. It’s perfect; no annoying beeping, and the timer reads 0:00 so it doesn’t need to be cleared before reuse.
