Apostrophes

Robertd, I don't believe you are following the rules for possessives correctly.

The rules are: - The possessive of a singular noun is always formed by adding "'s" to the end, even if the noun ends in an s.

• sentence's
• Robertd's
• Jonathan's
• Marcus's
• Epimenides's
  

- The possessive of a plural noun differs depending on whether the plural form of the word ends with an s or not. Plural forms ending with an s just get a final apostrophe; plural forms ending without an s get an "'s" just like singular nouns.

• cattle's
• fish's
• sheep's
• sentences'

Apologies: my understanding was that 's is almost always used for possessives, but that classical names (Jesus, Greek names ending with -es) take just the final apostrophe. (The motivation for my edit was something unrelated, but I saw one final-s-less possessive and tried to make them consistent.) In any case, I'm new here, and I'm grateful for the direction.

Which Bill Clinton heuristic

Can you explain me why you linked the word "which" in the Heuristic section of Backtracking to Bill Clinton during your 11/9/05 edit? : LarryLACa 10:19, 12 December 2005 (UTC)

I cannot take credit for that: it appears that edit occurred during the revision that followed mine (on 14 November 2005) by 151.188.16.20, which seems to be the source of some vandalism and other bizarre edits... Robertd 02:52, 14 December 2005 (UTC)

Quadratic Koch curves

Hello Robert. I am the main contributor of the list of fractals by Hausdorff Dimension. I saw you created nice images of the Quadratic Koch in 3D, congratulations ! Mine were rather badly made. In order to reuse your images for the french version of the article, it whould be nice to transfer those images on commons.wikimedia.org. Could you do that ? Thanks.Prokofiev2 (talk) 07:57, 1 April 2008 (UTC)

Thank you for the kind words---I'm honored and delighted that you find the images useful. I've uploaded the images with the same file names to Wikimedia Commons; please let me know if I've bungled it. Thanks, Robert. Robertd (talk) 23:46, 1 April 2008 (UTC)

Thanks, Robert, your images are now visible on the french wikipedia. 217.70.85.68 (talk) 11:49, 2 April 2008 (UTC)

Moore curve rules for higher dimensions

You're the right person to ask this. The rules for the Hilbert and Z curves are available in higher dimensions, whether based on L-systems or not, but the only description for the Moore curve in higher dimensions is "rotate a lower-dimensional Hilbert curve until the endpoints coincide" which while accurate is also very imprecise, like trial-and-error. As you've coded the Mathematica demo in the past, if you have a better description for a Moore curve construction (e.g., using a lower-dimensional Moore curve without any rotation, using an L-system etc), please consider adding it to the Moore curve article. -- 128.211.167.189 (talk) 20:42, 21 March 2014 (UTC)
