A lifetime ago I used to work in the construction field. I have every respect for the people who planned and built the pyramids. The level of coordination, resource management, engineering expertise would have rivalled the biggest projects of the modern day.
Sometimes its nice to be reminded we haven’t advanced all that far. For all the machinery and gadgetry we have today, some of the works still require the same techniques and methods used by our ancient ancestors. Like shifting heavy equipment onto its final position. Like rolling it on top of steel pipes and then using a bunch of pulleys and levers to just jimmy it to its exact angle required. For all the laser levellers we have, sometimes nothing beats a bit of clear tubing, water, string and a good eye to level a final coat of flooring.
