Why Europeans colonized America before Africa, in two maps and one story:
Map 1:
Northern Africa, bordering the Mediterranean, has been part of the Eurasian cultures for thousands of years.
South of that, it didn't get conquered until the 19th century, while America got conquered 3 centuries earlier despite being farther. Why?
For centuries, there was the Sahara barrier. The distance to cross was just too big. Impossible by foot, and only possible by sea through the Red Sea in the East, on the path to India, because of inhabitable stops on both sides
I explain in this article why going beyond ports was really hard. Basically: no Suez canal, hard to build/transport fleets, far from home, few local stops... Trade possible, invasion hard
So this is why, for centuries, Subsaharan Africa was out of reach.
Nuclear is the best source of energy across nearly all the factors that matter. It's the safest, cleanest, densest, most sustainable, geopolitically stable, predictable, dispatchable, and can be cheap.
1. SAFEST
It kills 1000x less than coal
Living close to a nuclear power plant for one year gives you less radiation than eating a banana (graph is logarithmic)
2. CLEANEST
Accounting for all the lifecycle of all energies, it's the one that emits the least CO2
I think the craziness of North Korea is most apparent in its architecture. 7 examples:
1. The Science & Technology complex has the shape of an atom from above
2. North Koreans like making their buildings' form represent their function. This is the entrance of the Zoo in the capital, Pyongyang:
3. The tallest building in the country is empty!
The Ryugyong Hotel was never finished. This Blade-Runner-style building has been empty for decades. The gov put LEDs on one facade, to use it... for propaganda
