Where does T'Challas sister learn science from

Where did the knowledge of making Greek Fire come from? A weapon that we still to this day don't know how it worked. Just so happened that Greeks figured it out Centuries ago. Where did the Knowledge of gunpowder come from? Chinese in isolation figured out how to make it. Where did the very labor intensive knowledge of processing Copper Ore come from? It was figured out in one small area in the Middle East. Now think about this to smelt pure copper from copper ore you have to have constant air blown on the smelting fire. This is so it gets hot enough to liberate pure copper. In Timna_Valley they didn't have bellows so 3 or 4 people would blow into tubes for hours to do it. How did they figure out that if you blow on a fire for 8 hours copper ore becomes copper? And they figured that out a thousand years before christ. History is littered with cases of gaining knowledge of some scientific/knowledge in isolation and independent of the rest of the world. In 3 different parts of the world the water driven hammer and anvil was created. In more that 4 different parts of the world advance Pyramid Construction happened. The bottom line is Wakanda figured out things way before the rest of the world. It was a natural process. Just how western civilization came to its knowledge. Just think of Wakanda like it was the Western World. They just were accelerated. They went through the same process we did. They started in Stone Age, Copper Age, Bronze Age, Iron Age, Steel Age, Industrial Revolution,, Information Age, Post Modern Age. They just did in isolation and with out the knowledge of the rest of the world. And they did it before the rest of the world.
