Great Pyramid models
13Jan2007 08:34 AM Filed in: Geometry-Math
This
morning I received an email from a website visitor in
the UK asking if I sold pyramid models. In keeping
with my recent resolution to not answer the same
question twice (by posting generic, FAQ-ish info
online, what a concept! 
, here is my reply:
=====
I don't actually sell pyramids, although it is a topic of great interest to me (especially the Great Pyramid
which I had the good fortune to visit in November 1992 after two decades of anticipation; quite an amazing experience there!)
I have a fold-up pattern in my book on page 189 of my book, Sacred Geometry Design Sourcebook,
which is available here:
http://www.lulu.com/content/583170
or, the foldup pattern (which has the correct proportions for the Great Pyramid at Giza, Egypt) is also
online on my website here:
http://www.intent.com/elysian/sgds_p189.html
If you use the model above, the important proportion (as close as you can get it) is:
diagonal length (also the radius of the circle used to make the foldup pattern) : 0.95105645
side length (the four base sides of the pyramid): 1.0
This will give the exact golden section (1.618034...) proportions for the pyramid faces (the two halves of each face
can be 'reassembled' to form a golden rectangle, as is shown on page 189.
In terms of someone to make you a model, any craftsperson that is good with math should be able to fashion you a model scaled to your requirements; especially for large items that would need to be shipped, I highly recommend finding someone local to your neighborhood/community (and local matierials) if possible for optimal environmental factors!
Since I get inquiries like these frequently, I'll post my response (you will be anonymous) to my blog today:

I hope this is helpful!
