This group has been pretty good about not posting off topic over the last 6 years (wow Polytopia for 6 years!)- but still a few slip through the cracks. I...
Thanks for that table Alan! My thoughts are that Theodorus first constructed it with compass and ruler- which gave the required precision without much...
I have a question--a comment to the original post stated that 17 is the first number for which the even-odd concept used in the proof of the irrationality of...
... If it is a multiple <http://en.wikipedia.org/wiki/Multiple_%28mathematics%29> of two <http://en.wikipedia.org/wiki/Two> , then it is an even number, else...
Thanks, I understand the example proof, but my question was whether there is something unique about 17 and its square root as implied in the post, other than...
Alan: Thanks--I was able to download McCabe's article on Theodorus's methods and answer my question. The previous reference I had was incorrect. --John...

Hello Dome People, I have a 22.68 Foot diameter 4-v Geodesic dome made of 1 inch conduit. This dome uses Hubs that were designed to speed and simplify...
Hi Alan From what I see, there are 9 different triangles for the 5f triacon at the domeclimber.com link. How many are there for Pete's 6f dome? There must be a...

Hey guys, I had made a whole bunch of animations of as many polychora as I could get net data (or figure it out) for back in 2004. I've finally found them,...
