How were the pyramids of Egypt built?

The pyramids of Egypt are the monuments that have aroused the most interest throughout history. The origin of the oldest dates back to 4,500 years ago and, contrary to what is believed, they were not built by slaves. The workers were free and charged species, and it is said that the pharaohs gave them products of very good quality. Now, the fact of how the pyramids of Egypt were built is something that very few manage to understand. Taking into account the primitive techniques of the time, it seems incredible that they were capable of moving stone blocks weighing several tons through the desert.Construction of the pyramids of EgyptIn 2014, physics experts from the Foundation for Fundamental Research on the Materia (FOM) and the University of Amsterdam shed light on how the pyramids of Egypt were built. The Egyptians used a very simple and effective trick to make sledges slide across the sand loaded with the gigantic stones and statues. Professor Daniel Bonn, the lead author of the study, explains that he and his team were able to show that by adding just the right amount of water on the sand, sliding friction is greatly reduced. In Ancient Egypt, what they did was wet the sand where the sleds passed to reduce the force required to push them in half. Now, it is important that the amount of water is just and necessary. This being the case, wet sand is twice as firm as dry sand, hence the sleds glide very easily.The fact that in Ancient Egypt sledges were used to transport stones and statues is something that is already known thanks to one of the walls of the tomb of Djehutihotep, head of one of the regions of Upper Egypt (1914-1852 BC ). The image shows a person pouring water onto the sand right in front of a sled. All the pyramids in Egypt were clad in polished white limestone to reflect sunlight and shine like a jewel. They were funerary monuments, so their main function was to host the tombs of the pharaohs so that the trip to heaven would be easier.
