History

An original entry was based on the book A Short Account of the History of Mathematics (4th edition, 1908) by W. W. Rouse Ball.

Geometry

http://www.1911encyclopedia.org/Dodecahedron: DODECAHEDRON (Gr. SccSerca, twelve, and Spa, a face or base), in geometry, a solid enclosed by twelve plane faces. The "ordinary dodecahedron" is one of the Platonic solids (see Polyhedron). The Greeks discovered that if a line be divided in extreme and mean proportion, then the whole line and the greater segment are the lengths of the edge of a cube and dodecahedron inscriptible in the same sphere. The "small stellated dodecahedron," the "great dodecahedron" and the "great stellated dodecahedron" are Kepler-Poinsot solids; and the "truncated" and "snub dodecahedra" are Archimedean solids (see Polyhedron). In crystallography, the regular or ordinary dodecahedron is an impossible form since the faces cut the axes in irrational ratios; the "pentagonal dodecahedron" of crystallographers has irregular pentagons for faces, while the geometrical solid, on the other hand, has regular ones. The "rhombic dodecahedron," one of the geometrical semiregular solids, is an important crystal form. Many other dodecahedra exist as crystal forms, for which see Crystallography.

Aesthetics

This section would benefit from more references, preferably from books on art and design rather than books on the golden ratio, many of which have a promoting or debunking POV.

Paulos, John Allen. Beyond Numeracy. New York: Alfred A. Knopf. pp. 98–101. ISBN 0-394-58640-9.

"Not surprisingly, the Parthenon in Athens can be framed by a golden rectangle, as can many of the smaller areas within it. Much other Greek art madu use of the proportions of the golden rectangle, as have subsequent works from da Vinci to Mondrian and Le Corbusier." p. 99

"The golden rectangle and the static harmony it exemplifies is typical of classic Greek geometry ...." p. 101

Devlin, Keith (1994). Mathematics: The Science of Patterns. New York: Scientific American Library. ISBN 0-7167-5047-3.

"Mathematical patterns sometimes reflect visual patterns that the human eye finds particularly aesthetic. One famous example of such mathematical pattern is the golden ratio. p. 108

"According to the Greeks, the golden ratio is the ideal proportion for the sides of a rectangle that the eye finds most pleasing. The rectangular face of the front of the Parthenon has sides whose ratio is in this proportion, and it may be observed elsewhere in Greek architecture." p. 108

Penrose discovered his tiling in 1974. p. 167 Dimensions are ratios of 1/φ, 1, and φ. pp. 167–69. Penrose tiling has local 5-fold symmetry, but the infinate tiling of the plane does not. p. 169.

Quasicrystal alloy Al_5.1Li₃Cu has 5-fold symmetry in the 5 rhombic facesthat meet at a single point, forming a starlike shape. Likewise, quasicrystal material Al₆₅Co₂₀Cu₁₅ has local 5-fold symmetry. p. 169.

Euclid

Mathematician and historian W. W. Rouse Ball remarked that despite the criticisms, "the fact that for two thousand years it was the usual text-book on the subject raises a strong presumption that it is not unsuitable for that purpose."

Nicolaus Copernicus

Nationality Polish:

While the Catholic Encyclopedia does not attribute a nationality, Encyclopædia Britannica and Microsoft Encarta introduce him as "Polish astronomer", while refering to the cities of his life by their German names, not the Polish ones.

Software update history?

Is there a place on WP that announces updates to the software on which WP runs? Was there a recent change that adds more buttons above the edit box? Finell (Talk) 18:03, 26 September 2006 (UTC)

Per the second question: there was a recent change at MediaWiki:Monobook.js, which added buttons. --Ligulem 18:20, 26 September 2006 (UTC)

Thanks. I would still appreciate, from someone, knowing where one can go to see recent changes to the software. For example, a software rev in late 2005 clobbered my signature, which used the documented Signature box trick on my User profile page. It took me quite awhile to find out what happened. Thanks again. Finell (Talk) 19:27, 26 September 2006 (UTC)

You can see the recent changes to MediaWiki by looking at the release notes in subversion. The developers keep a pretty good track of what they've updated. Hope this is what you're looking for. Shardsofmetal 22:03, 26 September 2006 (UTC)

Special:Version, which also lists the revision number from SVN. SVN root is http://svn.wikimedia.org/svnroot/mediawiki/trunk/phase3 (browsing ). --Ligulem 22:13, 26 September 2006 (UTC)

That is what I was looking for. Thanks. Finell (Talk) 16:24, 27 September 2006 (UTC)
