Dick, There is a discussion concerning my Dad's map of the double helix. Time Magazine flew either Watson or Glick to Rockefeller Center. After a few hours...
Hi I have put together an album of geometry and polyhedron related images and animations - http://freewebtown.com/adrian/geom/ A lot of the programs I wrote to...
Hi Folks, I'm sorry. Perhaps I missed the beginning of this thread. But the image I see is wonderful and I'd like to know more about it. It looks like...
... Each vertex angle of the equilateral triangle is 60°. The half-angle is 30°, and its sine is 1/2 and its cosine is SQRT(3)/2. ... Since the big circle is...
Alan, thanks for getting back to this. I just came in major sunburned, lol. Waiting for the gals to get ready to go sailing, and they took forever, I fell...

Hi all, Did anyone notice that I released Great Stella 3.1 and 3.2? :-) I didn't announce 3.1 on the list, and now 3.2 is available. For those who don't know,...
For irregular cuboctahedra, go to http://dogfeathers.com/java/hyperstar.html Then set HyperPlanes to CrossPoly (that's the 16-cell), Shell to #0 (of course),...
The truncated octahedron and the truncated tetrahedron have hexagonal faces that can close down and become the four hex planes of the VE. Michael Donovan...
Alan, yes, this is core! And you must get back to balls making balls making balls. Again the 230/232 crystal symmetry limit the strongest physical limit in...
yes, this is what I am talking about. Having email problems. Will check the site. Seems my posts don't go through. Michael ... faces that can close down and...
Rybo, The very best thing for visualization are ping pong balls. Concepts of line and points and planes only come at the end to define in terms of an 'old'...
