Hello, I had a question in numerical analysis. Any suggestions are greatly appreciated. (1) Given F(x) = 0, numerically find the roots. Essentially, split an...
Hey all, I have been working on a 6v geodesic dome design that requires only six strut lengths. (Based on the icosahedron) Using this theory; any frequency...
Harold, Check out this site: http://www.desertdomes.com/rev4calc.html Your information is incorrect. There are nine lengths of struts in a 6v dome or sphere....
Hello Allen, and all, Thank you for the website, Interesting. I have built a model of a 6v geodesic dome with 9 strut lengths (in 1987). Now I have built a 6v...
Harold, It sounds like your 6 strut design combines pairs of the 9-strut design that are similar in length. Since the differences are slight, with a model...
Is it possible? Sure. But you wouldn't be able to call it a geodesic dome, strictly speaking. It's amazing how even the slightest deviations become readily...
Hello All, Is there a formula for giving the number of possible configurations for connecting sequentially all twelve faces of a dodecahedron so that each face...

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...

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...
