[edit] Geometry of Complex Numbers

I am moving this to User:Pmurray_bigpond.com/Geometry of Complex Numbers while I am still investigating it.

If you are interested, ulimately I hope to build a java screen saver that does quasifuchan limit sets. (User:Pmurray bigpond.com forgot to sign)

Great you moved it. I might visit it from time to time.

About the java screen saver, I am not sure I understand what that has to do with Wikipedia. Enjoy! Oleg Alexandrov 05:09, 29 Mar 2005 (UTC)

Well, the screensaver isn't strictly to do with wikipedia, but seeing as I am going to the trouble of getting on top of all this math, it seems a shame not to write it down somewhere. Most of the stuff in Mobius Transformation is mine.

I already have a couple of other screensavers. One is an implementation of "quasitiler" (for which I had to find out about zonotopes), and the other projects world costline data onto the screen using various map projections and rolls the globe around in arbitrary directions - the idewa being that it allows you to see how the various projections distort the map. (User:Pmurray bigpond.com forgot to sign)

Got it. Just one remark. It is good to sign your posts. That is accomplished by putting four tildas one after another — ~~~~, which Wikipedia will replace by your username and date, like this: Oleg Alexandrov 05:36, 29 Mar 2005 (UTC)

[edit] Stereographic projection

Hello. Please note that Wikipedia conventions call for only sparing use of capitals in section headings, thus: Polar coordinates, not Polar Coordinates. See Wikipedia:Manual of Style. I fixed this in stereographic projection. Michael Hardy 21:34, 5 Apr 2005 (UTC)

[edit] Category:Mathematical methods

Hello. I am wondering what you are trying to do with Category:Mathematical methods. At the moment, it has Category:Algorithms as both a subcategory and a supercategory, which seems rather strange to me. Do you know why Category:Mathematical methods was created in the first place? I have no idea what articles this category is supposed to contain. -- Jitse Niesen 13:13, 15 Apr 2005 (UTC)

Yes, I think I confused myself. In one sense, computing is a subset of mathematics, so any algorithm is nessesarily mathematical. But otoh: many algorithms to not involve things that we think of as mathematical - sorting and searching. There's considerable overlap in the respect that matematical methods are often implemented on computers.

Added to this is the point that Category: Mathematical Methods is pretty empty. It shouldn't be. Many math pages contain useful recipies for doing things, although ...

Hmm, ok. How about this:

by mathematical method, we mean "useful recipies for doing common tasks", usually involving performing a sequence of steps. This category groups together pages which not merely contain such recipies, but are specifically about them. Although mathematical methods are often computer implemented, they are not nessesarily so. Recipies relating primarily to computing (eg: searching and sorting) are in Category: Algorithms.

The relation between the two categories would be via link, rather than making one a subcategory of the other.

Pmurray bigpond.com 01:36, 19 Apr 2005 (UTC)

I still don't see what you mean. The phrase "useful recipies for doing common tasks" seems to be a definition for an algorithm; for instance, algorithm states: "An algorithm [...] is a finite set of well-defined instructions for accomplishing some task." In particular, an algorithm does not need to be implemented on a computer.

I'm currently of the opinion that Category: Mathematical methods should be deleted. Can you think of any article that should be in Category: Mathematical methods and not in Category: Algorithms? -- Jitse Niesen 10:56, 19 Apr 2005 (UTC)

[edit] Mobius graphics

Hi, wanted to provide a big thank-you for adding the graphics to Mobius transformation. I'd read the term "loxodromic" I don't know how many times, and never had a clue that this is what it meant. So again, thanks!

Also, please continue work on the geometry of complex numbers. This promises to be interesting. Also, I don't know if you know this, but it might also be suitably distracting. Roger Penrose came up with something called twistors, which do to 4-dimensional space-time kind of what your geometry of complex numbers does to ordinary 2-D Euclidean space. Various famous formulas from math and physics, e.g. curvature, maxwell's equations, etc. take on a new weird and wonderful form when re-expressed as twistors. So please, keep at it. linas 13:02, 18 May 2005 (UTC)

[edit] Mobius graphics redux

Hi, The Mobius transform article also also defines the phrase "characteristic parallelogram". I was wondering if you could create one of your fantastic charts that has superimposed on it the characteristic parallelogram. I'm guessing what it will look like, but I want to know for sure. (I guess its rectangle for the elliptic xforms? and a parallelo only for the loxodroms; right????)!! Thanks, linas 21:13, 4 Jun 2005 (UTC)

Thanks. BTW, It is no accident that the loxodromic curves resemble the curlies seen in the mandelbrot set blowups. The mandelbrot set has embedded in it a pile of modular group-like symmetries. The loxodromic spirals are just one more bit of evidence. linas 05:46, 6 Jun 2005 (UTC)

[edit] Pencils

BTW, I think one of the requested math articles out there is to cover "pencils", maybe Lefshetz pencils or something like that. I have no idea if your pencils are those pencils. Would you know? linas 13:10, 18 May 2005 (UTC)

[edit] Uluru photos

On Talk:Uluru#photos you asserted: Also that caption "climbers ignoring warning signs" is biased. For all we know, they read the sign thoroughly. ... Saaaay - those photographs look very much like two of the ones I took when I was there, which I posted on my website for a while. If so, they are not used with permission. Well, that's the world wide web for you. Pmurray bigpond.com 04:05, 14 September 2005 (UTC)

On the assumption from the context of the assertion within the paragraph above you are referring to Image:Uluruwarning.jpg, I have notified user:LeeM who upoaded the image asserting s/he took it. It is a very serious assertion that someone has breached copyright and lied about it. Could you please clarify which photos you are referring to.--AYArktos 09:57, 14 September 2005 (UTC)

Apology added to uluru talk, AYArktos and LeeM notified. Pmurray bigpond.com 02:00, 17 September 2005 (UTC)

[edit] PD-user image tag

In the future, when you want to release an image you created to the public domain(like Image:Mob3d-hyp-arb-480.png), the best way to do so is just to add the following to the image description page:

{{PD-user|Pmurray bigpond.com}}

That results in

This image has been (or is hereby) released into the public domain by its creator, Pmurray bigpond.com. This applies worldwide.

and puts it in the Category:User-created public domain images.

I've added the tag to the image mentioned above, but you might go through and add it to the other images you've uploaded(or just tell me to do it, and I'll do it and point to your comment as justification). Thanks for your work on the 'pedia! JesseW, the juggling janitor 08:12, 2 October 2005 (UTC)

You'd tagged the top and bottom rows, but not the middle row. I've tagged them, now. Thanks! JesseW, the juggling janitor 08:32, 2 October 2005 (UTC)

[edit] Australian English

Hi PMurray. I reverted your edits to the above article because most of the content you added is covered in the article Australian words, clearly linked to the Australian English article. Cheers. Natgoo 00:40, 17 December 2005 (UTC)

Also, most of the material was not encyclopedic in tone. It read more like a blog, or the discussions going on in the talk pages. Stick to facts, and write in a neutral tone. None of this "here in canberra..." business. Imroy 02:48, 17 December 2005 (UTC)

[edit] Australian words

Oh great, you've done the same hatchet job to this article. For god's sake, read the article first before adding to it! You've added a number of entries to the general section that are already described in later sections. And once again, take care with what you write. Do not include a joke when it's not needed, or at least introduce it properly. Don't just put it in brackets with 'P.S...'. We're trying to write an encyclopedia here. Imroy 03:05, 17 December 2005 (UTC)

[edit] Image Tagging Image:Mobius23622.jpeg

This media may be deleted.

Thanks for uploading Image:Mobius23622.jpeg. I notice the 'image' page currently doesn't specify who created the content, so the copyright status is therefore unclear. If you have not created this media yourself then you need to argue that we have the right to use the media on Wikipedia (see copyright tagging below). If you have not created the media yourself then you should also specify where you found it, i.e., in most cases link to the website where you got it, and the terms of use for content from that page.

If the media also doesn't have a copyright tag then you must also add one. If you created/took the picture, audio, or video then you can use {{GFDL}} to release it under the GFDL. If you believe the media qualifies as fair use, please read fair use, and then use a tag such as {{fairusein|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair_use. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other media, please check that you have specified their source and copyright tagged them, too. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that any unsourced and untagged images will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. Thank you. Longhair 01:36, 3 February 2006 (UTC)

[edit] NandFullAdder.png

What did you use to draw NandFullAdder.png?

I forget - might have been something on the mac. BTW: you need to add your name with four tildes if you want me to reply on your talk page.

[edit] Your username

The bigpond.com part of your username is not appropriate per Wikipedia:Username#Inappropriate usernames. You'll have to choose a new account name, and make a request at the Wikipedia:Changing username page. (You could also simply start a new account, but I suppose you want to keep your established edit history attributed to the new name. If you feel your username does not violate the rule we can request further comments at WP:RFC/NAME first.) In the meantime please avoid making edits from this account which are not related to the name change. Thank you. Femto 15:38, 6 December 2006 (UTC)

I saw the namechange failed because User:Paul.Murray is already occupied by a banned vandal with only one edit. User:Paul Murray is still free though (the similarity should be no problem in this case, asked at Wikipedia talk:Username#"Paul Murray" vs. "Paul.Murray" to make sure, I don't think anybody can reasonably object), just try again? Femto 16:03, 10 December 2006 (UTC)

Well? Femto 21:45, 15 December 2006 (UTC)

Re: [1] You didn't catch the reply here Wikipedia talk:Changing username/Archive 2#names with spaces? Just needs another underscore. This should work: {{subst:Renameuser|Pmurray_bigpond.com|Paul_Murray|current name infriges policy}} -- ~~~~ Good luck! Femto 10:28, 18 December 2006 (UTC)

As you requested, your username has now been changed from Pmurray bigpond.com to Paul Murray. If you haven't done it already, please remember to move your user page and your talk page using the "move" tab on the upper right-hand side of your screen. Redux 13:20, 19 December 2006 (UTC)

[edit] Move is done

So there.

Glad that's over, huh? Merry (ex)christmas and happy editing! Femto 12:11, 24 December 2006 (UTC)

[edit] Men's rights

Because of the controversy surrounding this subject, and a recent call by an editor for others sympathetic to his viewpoint to register as editors on Wikipedia and help with editing, please do not add information to this article without also providing a source(s), in the article, supporting the information that you are adding. Thanks. -- John Broughton (☎☎) 15:03, 30 January 2007 (UTC)

[edit] Font on my signature

Paul - I'm not sure if I understand your question. If you edit a page (like this one), you'll see the raw code (including the font) for my signature; that's why it reads as it does. If you're asking the more general question - how does any editor customize their signature, the answer is to use "my preferences" (on the top of any page, once logged in), and at the user profile tab, check "raw signature", then put whatever you want in the signature box.

You'll find that info and more at Wikipedia:Customisation#User name and signatures andWikipedia:Sign your posts on talk pages (bad title for the page, since it also includes customization information). If you really want to customize your signature, take a look at User:Athaenara/Gallery, but be aware that there is movement afoot to sharply cut back on the maximum signature length (raw characters visible when in page edit mode), so many of the signatures may be unacceptable in the near future. -- John Broughton (☎☎) 00:30, 31 January 2007 (UTC)
