The ancient Egyptians utilized neither wheels nor work animals for the majority of the pyramid-building era, so the giant blocks, weighing 2.5 tons on average, had to be moved through human muscle power alone. But until recently, nobody really knew how. The answer, it seems, is simply water. Evidence suggests that the blocks were first levered onto wooden sleds and then hauled up ramps made of sand. However, dry sand piles up in front of a moving sled, increasing friction until the sled is nearly impossible to pull. Wet sand reduces friction dramatically beneath the sled runners, eliminating the sand piles and making it possible for a team of people to move massive objects.
Pyramids = basic engineering shape for a sturdy structure. Wide base, tapered top. A lot of early monumental structures were constructed with that basic concept in mind.
Yeah, it’s been linked to systemic racist thought patterns (which are often unintentional but should be acknowledged). I explain it to people like this: take a handful of sand and turn your fist so that your palm faces perpendicular to the ground. Now release the sand slowly… What shape does it form? It isn’t rocket science.
The key to happiness is not having expectations, unfortunately that is not always healthy. It’s like nature, evolution comes with just the right pressure. Life needs a little grit, unfortunately, but obviously not /waves arms at generally everything. Hoping for a Star Trek future where we can pursue becoming better people without the need to fight for our basic needs.
