The really mad thing is that while you say it's centuries of abstract thinking and the like, it was only 50 years between the discovery of X-rays and radiation and the first atom bomb, or 40 between the first idea that you could use fission to make a bomb. Neutrons and the nuclear chain reaction was only theorized in the 30's, about 10-15 years before the first nuclear bomb was detonated. But likewise, there was only a few decades between the first airplane and the first person on the moon (although rocketry goes back hundreds of years. Actually TIL rocketry is older than Newton's laws of physics) | ||

While rocketry is older than Newton, even in 1920, it was widely believed that rockets would not work in space (and therefore couldn't get us to the moon). https://www.astronomy.com/today-in-the-history-of-astronomy/... Luckily, the Times did issue a correction - almost 50 years later, on July 17, 1969. The day after NASA launched the first mission to the moon. | ||

It's funny to me to imagine that the whole time humans were doing basically anything on this planet, nuclear fission was also already happening in a few places around the world. I wonder how much science would've been jump-started if we'd found any of the natural nuclear reactors prior to having figured fission out already. | ||

as an example, complex numbers were from the abstract thinking of centuries ago, on which the modern physics derive much value from. | ||
