Request for edit summary
When editing an article on Wikipedia there is a small field labeled "Edit summary" under the main edit-box. It looks like this: The text written here will appear on the Recent changes page, in the page revision history, on the diff page, and in the watchlists of users who are watching that article. See m:Help:Edit summary for full information on this feature.

Filling in the edit summary field greatly helps your fellow contributors in understanding what you changed, so please always fill in the edit summary field. If you are adding a section, please do not just keep the previous section's header in the Edit summary field - please fill in your new section's name instead. Thank you. – Oleg Alexandrov (talk) 23:25, 8 August 2007 (UTC)

Are you a robot or a guy who really likes to copy and paste?

No, I'm sorry for being a smartass. It's just that I was doing an overhaul of cartographic notation, outlined my intent in the map projection talk page beforehand, and didn't want to repeat it over and over in the edit summary. -Ben pcc 15:55, 9 August 2007 (UTC)
 * I am not a robot. :) I use ~

Note
I replied your question above.

Regarding this edit, first note that your browser damages Unicode (scroll to the bottom of the diff).

Also, did you indeed copy stuff from MathWorld? That is not OK.

You can reply here. Thanks. Oleg Alexandrov (talk) 03:05, 13 August 2007 (UTC)
 * I cut out the mathworld text for now, as I don't want us to run into copyright trouble. If you can get that text from somewhere else (and with a references, if possible), we can put it back in. Oleg Alexandrov (talk) 03:19, 13 August 2007 (UTC)

Wow, that's bad. I just edited again as I was reading this, there was a minor problem, so it must be ruined again (in fact, I got an edit conflict writing this). I'll see if I can figure out how to fix that. I'm using Firefox 2.0.0.1. Thank you for letting me know.

It wasn't blatantly copied, it was read, understood, and rewritten (they used some inconsistent notation and a redundant case statement). It's not exactly original research or anything like that, it's more like "copying" 2 + 2 = 4, except a topic of higher math; I don't believe it's worth citing but I don't know. It's certainly not a copyright thing and, again, not one character was copy + pasted, they look quit different. For reference: central, forward, backward.

Thank you for looking out for me. Please let me know if you think it's alright if I put it back in. -Ben pcc 03:26, 13 August 2007 (UTC)
 * I think it is OK to use stuff from MathWorld, as long as, as you said, you read it, understood it, and wrote it in your own words. Adding the appropriate links to MathWorld in the external links section could be good too (citations are good simply for verification, if the reader wants to know more on the topic or to double check what is being said).
 * I took that text out temporarily as a precaution. I think it is fine if you would like to put it back in. Oleg Alexandrov (talk) 15:00, 13 August 2007 (UTC)

... and a style note
Sorry to bug you again. :) In math notation variables must be italic, so either n or $$n$$ but not simply n. I fixed this in the finite difference article. Cheers, Oleg Alexandrov (talk) 02:42, 14 August 2007 (UTC)

Thank you. I want to do it right, don't be sorry. -Ben pcc 03:40, 14 August 2007 (UTC)

rvannatta is local=== ==

yes. I'm local. think  'West Oregon Electric'   and "www.vannattabros.com" web site.

as for the railroad in Mist, I pulled that because to my knowledge it is wrong or at least misleading.

I believe the railroad that you are referring to is the "Kerry Line" that came from Woodsen over Nicoli Mountain (and through it) arrived at Fishawk, and had the roundhouse at Neverstill west of Birkenfeld and mostly supported logging west of there.

I don't regard Mist is being part of that route.Rvannatta 02:32, 12 September 2007 (UTC)

I'm not sure which line I'm talking about to be honest, but more then one person (old natives) tell me that there was a railroad through Mist which was taken out because it was no longer necessary. One person told me that circa 50 years ago the Nehalem would freeze so thoroughly that rail tracks were temporarily laid over it.

Nice to here from you. I visit Mist often and used to live there with my parents (who are still there), now I'm in Portland; thank PSU for robbing me from that firry wonderland. -Ben pcc 03:01, 12 September 2007 (UTC)

Do understand that there were temporary branch railroads 'everywhere' as in about down every ridge. Logging roads and trucks didn't not exist, so temporary railroads were layed out between 1900 and 1940, and logs were drug with cables to the tracks and loaded. these tracks were then relocated to the next site. these spur roads were often no more than half a mile apart. to my view the mainlines are news these tempoary spurs are just that---about as news worthy as a tempoary truck road tohaul logs....

Easily seen remanents of a RR --- if you look  A railroad crossed the Nehalem where the bridge is at  Big Eddy Park. ---if you look accross the Or 47 from the present bridge you will see some RR piling in the low ground there.

Also if you look at the ground by the Apiary Road intsection you can see the RR cuts there. The power line is along them and a cut turns up the Apiary road---which is a converted RR all the way to the Rock Quarry. Rvannatta 02:44, 13 September 2007 (UTC)

inline TeX
MediaWiki didn't do anything to your inline math; I changed it. Please see Manual of Style (mathematics). Inline Tex usually fits badly---it is the wrong size and usually badly misaligned. Michael Hardy 23:56, 17 September 2007 (UTC)

Hmmn, ok. But why didn't I see an edit? &mdash; Ben pcc 23:57, 17 September 2007 (UTC)

I don't know. It's in the edit history. Michael Hardy 00:02, 18 September 2007 (UTC)

From the "Very simple formulas" section of that page, it says that either way is ok, doesn't encourage one over the other, and discourages changing what others have done. It does discourage inline png, but my math wasn't png, it was rendered as text. For me anyway. If noone objects I'll continue using math markup inline as it's far more flexible.

Right, it's in the history. I didn't see it when I edited after you... lag of some kind I guess. &mdash; Ben pcc 00:05, 18 September 2007 (UTC)


 * I don't think I've done this except in cases where inline TeX looks really really horrible (which is usually). Michael Hardy 00:31, 18 September 2007 (UTC)

Kutta's third-order method
Do you happen to know a reference for Kutta's third-order method, which you listed in the list of Runge-Kutta methods? I did not manage to find it in any of the Hairer books. Cheers, Jitse Niesen (talk) 16:46, 29 October 2007 (UTC)

I poked around and I couldn't locate my source. I think I transcribed it from one of Butcher's papers but I can find the darn thing. Sorry. &mdash; Ben pcc 21:26, 1 November 2007 (UTC)

Disputed fair use rationale for Image:MicrogravityUniversityLogo.png
Thanks for uploading Image:MicrogravityUniversityLogo.png. However, there is a concern that the rationale you have provided for using this image under "fair use" may be invalid. Please read the instructions at Non-free content carefully, then go to the image description page and clarify why you think the image qualifies for fair use. Using one of the templates at Fair use rationale guideline is an easy way to ensure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If it is determined that the image does not qualify under fair use, it will be deleted within a couple of days according to our criteria for speedy deletion. If you have any questions please ask them at the media copyright questions page. Thank you.BetacommandBot 20:22, 6 November 2007 (UTC)

Re: Rename image please
Done. More detail on my talk page, to keep conversation in one place. Oleg Alexandrov (talk) 03:54, 30 January 2008 (UTC)

Speedy deletion of Tridiagonal matrix algorithm/Derivation
Please do not move pages to nonsensical titles. It is considered vandalism. If you would like to learn more about moving pages, please see the guidelines on this subject. If you would like to experiment with page titles and moving, please use the test Wikipedia. Thank you.

If you think that this notice was placed here in error, you may contest the deletion by adding  to the top of the page that has been nominated for deletion (just below the existing speedy deletion or "db" tag), coupled with adding a note on the talk page explaining your position, but be aware that once tagged for speedy deletion, if the article meets the criterion it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the article that would would render it more in conformance with Wikipedia's policies and guidelines. Lastly, please note that if the article does get deleted, you can contact one of these admins to request that a copy be emailed to you. Potatoswatter (talk) 20:43, 8 September 2008 (UTC)


 * In the past I've improperly named articles (not just this), but it's no vandalism, not even a page move. I wrote it myself, geez. &mdash; Ben pcc (talk) 17:06, 9 September 2008 (UTC)

Navier-stokes picture
Ben pcc,

I saw your elegant picture on the page on Navier-Stokes equations (NSConvection.png). What did you use to create it?

59.96.9.98 (talk) 07:40, 1 October 2008 (UTC)

Thank you! I used Cinema 4D, but that is overkill. Other software (2D?) would be more appropriate, but I only have experience in 3D so I can't make a recommendation. Inkscape looks interesting but I tried it and it seems pretty incomplete. -Ben pcc (talk) 19:46, 1 October 2008 (UTC)

Fluid dynamics task force
Hello Ben pcc. The Wikiproject Fluid Dynamics has been revived as a task force to WikiProject Physics. As a valuable contributor to core issues of fluid dynamics, we can certainly use your help. If you like to consider to do so, you can have a look at the task force page WP:FDTF (where it is also possible to sign in as a member), and its talk page (WT:FDTF). Best regards, Crowsnest (talk) 18:36, 10 April 2009 (UTC)

thanks and invite
Thanks for the excellent and crazy photo of Mount Hood. I didn't notice any seam problems at normal magnifications.

Since you seem to be from Oregon, perhaps you'd be interested in our WikiProject?

Hey, thanks for the compliment. I'm not that active on Wikipedia nowadays and when I was active tended to contribute all over, so I avoid joining projects. There are many seams but just one really sucks, it's on a snow ridge near the center right.

Thanks again! -Ben pcc (talk) 21:03, 21 July 2009 (UTC)

Hard drive
I too am here for the incredibly detailed hard drive photo.

One thing caught my attention, it is an item I think might be incorrectly labeled. There is a reference to a "dessicant bag". I think this is rather a filter meant to capture loose particles in the drive. The position of the item is such the spinning platters force air through that channel and hence through the filter. A desiccant bag, on the other hand, is a consumable thrown in packaging typically meant to cover the voyage to the consumer... absent a way to cook out the moisture, such a thing wouldn't last very long before the desiccant was depleted inside a functioning hard drive. Reswobslc (talk) 09:04, 8 January 2010 (UTC)


 * Piss. That was a while back but I still remember a moment of hesitation since desiccant bags don't last. I put the text over it in raster so there's not much I can do short of redoing the whole thing. Might be a good idea anyway since I have access to much better cameras, and since hugin is a lot better then it used to be. I thought of just labeling it with numbers so it can be used in other languages, but I like it looking like a poster better. Someday, if I'm bored enough... thanks for the compliment and for catching this mistake. -Ben pcc (talk) 19:29, 9 January 2010 (UTC)

link to "complete"?
In this edit, what did you intend the reader to see when they click on complete? That is (as one would expect) a disambiguation page. There is a related article called complete metric space, but it's not really the same idea, since the Chebyshev polynomials could be said to be complete as a basis of a smaller space than the Hilbert space that they span&mdash;in particular the space of finite linear combinations of Chebyshev polynomials. If there's no appropriate article, a new red link would seem to be in order. Michael Hardy (talk) 18:41, 23 August 2010 (UTC)


 * Sorry about that, it was a copyedit of something I wrote about two years ago. Complete metric space was intended and the context is with sum not truncated, so smaller space isn't meant. Merci! -Ben pcc (talk) 19:06, 23 August 2010 (UTC)

I'm not sure complete metric space really fits, though. The idea should be that there is no nonzero function in the appropriate L2 space that is orthogonal to all of the Chebyshev polynomials. If you omit one of the Chebyshev polynomials, then the remaining ones still span a complete inner product space, but they're not complete in the relevant sense.
