Hey smart people, so a few weeks ago we made a video about the pyramids, and how, while they are pretty heckin' impressive, we can trace the evolution of their construction and see the ancient Egyptians using trial and error, and even making a few mistakes, which basically tells us they didn't need aliens to build them, they just needed science.
You guys really liked that video, but a few of you were… a little bothered that, despite the fact it was called "WHO built the pyramids?" that I didn't talk about HOW the pyramids were made.
Soooo, let's talk about it!
[OPEN] The hundred-plus pyramids scattered around Egypt were all built a bit differently, but we're gonna focus on THE BIG ONE.
Let's review the stats!
The Great Pyramid originally rose more than 146 meters tall and contained about 2.3 million stone blocks.
But the start of any construction project truly begins with the foundation, which is impressive in its own right.
Its base is level to less than 2 cm, it's square to within 11 (cm), and its edges are aligned to the compass within 3/60ths of a degree.
This precision is pretty incredible since compasses didn't actually exist yet, and since forty-five hundred years ago the North Star was in a completely different place.
