Comments on: Icosahedron Polyhedra?-You Had Me At Icos… http://www.comingunmoored.com/2009/04/iscosahedron-polyhedrayou-isco/ At last I had mastered the low art of coming unmoored. -- Joe Androe Thu, 20 Oct 2011 00:22:52 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Mr.Kári Thomsen http://www.comingunmoored.com/2009/04/iscosahedron-polyhedrayou-isco/comment-page-1/#comment-1768 Mr.Kári Thomsen Sat, 20 Mar 2010 20:45:15 +0000 http://www.comingunmoored.com/?p=1216#comment-1768 Hi Cayenne The Easy Domes polyhedra has its basic in the icosahedron - 20 similar triangels. Even the traditional dome-houses seen past 20 30 years build in triangels also make use of the same Platonic polyhedra - the icosahedron. The difference from the triangeling system, where the struts carry the load, to the Easy Domes concept - where the triangels (6 to each hexagon and 5 to each pentagon) are implemented into a plane or plate structure, is to carry the load from top, crossing the edges and downwards to the plint(basement. Basic difference is: the geometrical triangel polyhedra made from the icosahedron is stable, while the Easy Domes plate-structure is unstable - without its plate. The triangeling system has advantages - and big disadvantages being difficult to erect and as a very long time job to mount and finish - with advantages in no limits in size if the triangels have a high frequence. To this a dome can be built in several thousands of squaremeter. The Easy Domes plate structure has big advantages if you think of building domes as family-domes or buildings upp to a few hundred squaremeter. It is easy to erect, quick to mount and you have no need for special connectors. The disadvantage is that the building sections - hexagons, pentagons and quadrangels can not be too big. The weight gets to high, the sections difficult to transport and the strength of each sections makes also problems if it becomes too big. So - buckuball, soccerball - or football......it is actually called a Truncated Icosahedron. The fifth figure of Platon, or the carbon molocule....you will find the figure in natur environment from micro to small to big examples...... God luck! Hi Cayenne

So – buckuball, soccerball – or football……it is actually called a Truncated Icosahedron.

The fifth figure of Platon, or the carbon molocule….you will find the figure in natur environment from micro to small to big examples……

God luck!

I'll ask Lynn to correct. Cayenne, thanks for letting us know. I’ll ask Lynn to correct.

Icosahedra are made of 20 triangles. It's part of a buckyball or whatever you want to call a soccerball shape of pentagons and hexagons. And polyhedra just means 3d shapes with flat sides, so is redundant if you've already specified the particular polyhedron (icosahedron or whichever.) Actually the logo on their site is an icosohedron. Um, it’s not an icosahedron. Icosahedra are made of 20 triangles.
