[edit] Polyhedron club?

Hi Guy,

User:RobertAustin asked me to make a user box template for people who like polyhedra. You can add it to your main user page if you like it. You can see others who use it at (Special:Whatlinkshere/Template:User_Polyhedron). Tom Ruen 05:50, 7 January 2007 (UTC) ADD

This user is interested in polyhedra.




[edit] Unspecified source for Image:Polygons.png

Thanks for uploading Image:Polygons.png. I noticed that the file's description page currently doesn't specify who created the content, so the copyright status is unclear. If you did not create this file yourself, then you will need to specify the owner of the copyright. If you obtained it from a website, then a link to the website from which it was taken, together with a restatement of that website's terms of use of its content, is usually sufficient information. However, if the copyright holder is different from the website's publisher, then their copyright should also be acknowledged.

If you created/took the picture, audio, or video then the {{GFDL-self}} tag can be used to release it under the GFDL. If you believe the media meets the criteria at Wikipedia:Fair use, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use.

[edit] Aircraft

I'm firmly of the opinion that it's an aircraft if it flies through the air; as in non ballistic.

Are you seriously claiming that for example, the flying bedstead is not an aircraft?

FWIW for rockets and all other jet powered VTOL vehicles the lofting surfaces are within the engine.WolfKeeper 15:01, 4 September 2007 (UTC)

[edit] Tailless

Look like we will have to agree to disagree on the terminology - no problem I have raised the issue at Wikipedia talk:WikiProject Aircraft for others to comment. MilborneOne 21:45, 25 September 2007 (UTC)

[edit] Polyhedron‎ Intro

Hihi. I've again removed the quote and preceeding paragraph. While the quote is something you might find in a paper or textbook, I don't think the fact that mathematicans can't agree on it is especially relevant, as there's a definition directly above the statement. Also, no sources. "Oft-quoted" and "seldom respected" are both pov statements, unless you can provide a source. "Us" is also pov and informal. Anyhow, gimme a shout if you still think it should be included. Thanks! Fin©™ 12:45, 26 October 2007 (UTC)

Hello. "Pov" means "point of view", articles should conform to a neutral pov. I would consider "seldom respected" to be your own personal opinion, unless you can provide a reputable source - you said it was well discussed by experts, provide a link if you can. Anyway, I've restored an edited version, without the pov, and put a tag for style at the top of the article - its written like discussion/essay/paper. Much thanks! Fin©™ 16:48, 26 October 2007 (UTC)

[edit] Bodies and cells

From Talk:Polyhedron, I do not think your claim We do not talk of the "cell" of a polyhedron but of its "body". is true. (You can search the term "cell" inside the talk page.) However, I will not do the edit that is the same as User:58.177.85.161. Instead, I will add one link in the term "cell" that is appeared inside Polyhedron. QQ (talk) 20:59, 1 March 2008 (UTC)

See also Polytope#Convex_polytopes, the table on element names. It seems like there's two parallel sets of terms from opposite directions, so both could be correct, so a body is a n-face in an n-polytope, always only one of course, but equally a polyhedron itself could be called a cell naming from the bottom. Well, anyway I guess it comes down to when people actually want to talk about an n-face of an n-polytope! Perhaps there is a real difference. Perhaps body can imply solidness, including interior, like the face of a polyhedron is considered a solid surface, while a polygon could be solid or not. Okay, I give up, but would like it if the polytope table was clarified if wrong or any, since I put body there as n-face! :O Tom Ruen (talk) 23:46, 1 March 2008 (UTC)
Sorry to take so long to reply, I have been away. For a line segment on its own, we do not talk of it as a "side" or "edge": it only becomes a side or edge when we use it to make a polygon. For a polygon on its own, we do not talk of the "face" of the polygon but of its "interior" or (more recently) its "body". When we use the polygon to construct a polyhedron then it becomes a "face" of the polyhedron, or if we use it to construct a tessellation then it becomes a "tile". Similarly with a polyhedron: on its own it has an interior or body, but when we use it to construct a polychoron or spacefilling it becomes a "cell". To summarise, terms such as "face", cell" and "edge" are not used when the object is being discussed in its own right. Hope this makes sense? (Tom, I'll have a look at your table separately). -- Steelpillow (talk) 17:57, 8 March 2008 (UTC)

[edit] Wearie-Phelan bubbles

Hi Guy. I overstepped my knowledge but put a picture of your space-filling polyhedra for Wearie-Phelan bubbles at: Hexagonal_truncated_trapezohedron#Wearie-Phelan_bubbles. Hexagonal_truncated_trapezohedron is a topologically equivalent polyhedron anyway to the irregular tetrakaidecahedra. Hopefully I colored the faces well, wanted to show a different color for each face type. Feel free to replace or destroy as my failed work necessitates! Tom Ruen 23:53, 29 October 2007 (UTC)

[edit] Kite challenges

I placed a reply on my talk page to your question on unpowererd kite that has powered harness or mobile anchor. Joefaust (talk) 20:12, 10 March 2008 (UTC)
