Hi Adrian: Thanks for the new photos of the construction methods for your models. I like your cardboard and cloths peg jig. These sort of things stick in my...
Works fine in my eMac, Safari & Netscape, & Cortona ('tho the latter doesn't show as much labels of the buttons as usual). Beautiful! Nice work John..--danu ...

... talk to No thanks, John. I saw above you mentioned brazing. I probably need to get into a bit of that. I made one model that way, I think. Brazing doesn't ...
Hi dharmraj ... Thanks for posting the photos. The models look great. The first one especially looks like it might have taken some time and effort to build! ...
Hello: I got all 24 mites turning inside out in the cube. I put together a small animation of the 24 A modules of the tetrahedron inside the cube moving to...

Alan, I went to all these sites but none convert 3-D to 2-D or vice versa. Again I dont think it is posssible even tho I posted someone elses mathematics that...
Hi Armin Please elaborate. I don't get it. Paul says:Volume: sqrt(2) / 12 * edgelength^3 http://astronomy.swin.edu.au/~pbourke/polyhedra/platonic/ Is this just...
Hi Adrian Can you show how to find the volume of a cube with unit edges when we take the regular tetrahedron as unit volume? And what is the volume of that...
Hi Dick ... Volume of a tet, edge 1 = (1^3)/sqrt(72) Volume of a cube, edge 1 = 1 cube/tet = sqrt(72) = approx 8.485 Likewise, comparing the sqrt(2) edged...

Hi Adrian Okay. Thanks. I get it. The rhombic dodecahedron which has unit length long diagonals(same as tet edges) has a volume of 6 tets. What is the tet...
Hi Dick ... It is a scaling, so the volume is 6 times the cube of the reciprocal of the original rhombic dodecahedron edge length. Adrian. -- Adrian Rossiter ...
