[Engineer]

Dear Engineers & Science Teachers,

In 2006 I was doing research for a university study in Australia concerning the construction of the Pyramids at Giza. Working with real excavated artefacts and ancient documents I was able to discover an ancient type of pulley that is unknown in the modern world until now. I am a mechanical fitter and people consider that my knowledge of mechanics at a practical level assisted me with this discovery.

This ancient pulley walks up (or down) steps in a similar way to a three wheel step-trolley and I firmly believe that this is how the ancient Egyptians built their Pyramids. The Giza Pyramids have steps of course, which I have termed "racks" and of course there are four "racks" in a square based Pyramid. The wooden ancient Egyptian Pinion-Pulleys made positive engagements with the Pyramid's stone "racks" carrying a stone block each, rotating as they were being hoisted with ropes. No ramps were required as the Pyramid itself was used.

This ancient pulley has a mechanical advantage of 2.8, thus is a simple machine and proves the Greek historian, Herodotus to be absolutely correct as he recorded wooden machines made of short wooden planks were used to raise the blocks of stone.

These planks only needed to be the side length of a Pyramid block which is about one metre and were easily carried also, as Herodotus also records. Well, Herodotus was only writing what Egyptian Priests told him and Egyptian Priests recorded history as part of their duties.

A working model has been made and a book about all of this has been published and I wish the World's people to know of this. This book is dedicated to the Egyptian people to promote "new awareness of their intelligent and innovative glorious historical past".

Get yourself a copy of the illustrated tutorial book and start teaching the truth about ancient Egyptian engineering techniques which cover the three classes of lever principles from an ancient Egyptian perspective.

Best Regards to you all,
