El misterio del corte de granito egipcio finalmente fue resuelto

How could the ancient Egyptians cut solid granite without steel, iron, or modern tools? The granite blocks in the King's Chamber of the Great Pyramid have baffled engineers and archaeologists for decades. Some joints are so precise that a sheet of paper can barely fit between the stones. But granite is one of the hardest rocks on Earth. So how did a Bronze Age civilization achieve such precision? 🔔 Subscribe:    / @primeroshumanos-x7h   In this documentary, we explore how experimental archaeology and modern materials science finally revealed the true secret of Egyptian engineering. This video explores: • the granite blocks of the Great Pyramid • the King's Chamber of Khufu • the limitations of copper tools • the science of tribology • corundum and emery as abrasives • experimental archaeology • and why the true answer is more impressive than any fanciful theory Based on studies in experimental archaeology and materials science. 📚 Academic sources on stonework in the Ancient Egypt https://doi.org/10.4324/9781003269922 https://www.cambridge.org/core/journa... https://core.tdar.org/document/423263... https://www.si.edu/spotlight/ancient-... https://www.nms.ac.uk/discover-catalo... #ancientegypt #pyramid #history
