It's hard to tell from this article what it's about. I suspect it refers to the logical abacus built by W. Stanley Jevons, also called a logical piano. But the article has links to pictures of ordinary abacuses, which are quite a different thing. There is also a hypothetical machine called an abacus machine which was introduced by Lambek for discussions of computer science. The linked pictures of abacuses are also irrelevant to Lambek's abacus machines.

This article needs to be made more lucid. I'm not qualified to do this myself, so I hope some expert will come by to clean it up.

This article is copied word for word from the 'Abacus' entry in the 11th Edition of Encyclopedia Britannica. The examples mentioned in the Britannica article are machines discussed by W. S. Jevons (Element. Lessons in Logic, c. xxiii), John Venn (Symbolic Logic 2ed, 1894, p. 135) and Allan Marquand (American Academy of Arts and Sciences, 1885, pp307) : ) The linked pictures of ordinary abacuses don't have much to do with the article as you said, so I'll remove the links. Should it also be mentioned that this article is based on the Britannica article?—Preceding unsigned comment added by 67.70.149.130 (talk) 00:14, 24 February 2008 (UTC)


[edit] Turing machine?

This article needs to mention something about whether an Abacus can simulate a Turing machine. MrVoluntarist 15:27, 15 March 2007 (UTC)

[edit] AfD

I will nominate this article for deletion unless it is improved and shown to be significantly different from abacus--Cronholm144 00:14, 13 May 2007 (UTC)
