Melissa Ward said:I wouldn't say that's quite true! Honestly, technology tends to take these massive leaps forward right during and immediately after a conflict. Look at World War II—it practically handed us nuclear energy, microwave tech, the entire semiconductor industry, jet engines, rockets, and so many other incredible breakthroughs!
Actually, most of that was basically already there before WWII—except maybe semiconductors, which came later. But, say, nylon came out of WWII (thanks to parachutes and socks being side products).
Radar (microwaves)—that’s what basically saved Britain in 1940. It existed, but without the war, it probably wouldn't have been ready for use back then. Early versions of jet engines and rockets (the Chinese were using rocket tech since gunpowder was invented, I guess) were also around before WWII. Even nuclear reactors existed before WWII—it was just the bomb itself that got built during the war.
So, it turns out none of that stuff actually "came from" WWII. 😬
Take the Sherman tank, for example. It helped the Americans win against Germany, and it was designed before the invasion of the USSR. But mass production didn't really kick in until late 1941. Funny enough, that's exactly when the tide turned on the Eastern Front. And yeah, the Sherman tank was an American design.
