[edit] Wikipedia:Articles for deletion/Alleged causes of Hurricane Katrina

I realize that there were strong feelings on both sides with respect to the outcome of the AfD for this article, now located at Alternative theories regarding Hurricane Katrina. I would like to assure those who expressed concerns about the content, tone, and potential for degradation of this article that I intend for it to continue to exist only as long as is necessary to draw the contributions of fringe theorists away from the more substantial Hurricane Katrina articles. Once interest in this topic dies down, I'll quietly trim and merge this information into the appropriate general-topic articles. In the interim, I will carefully watch this page to prevent it from being abused, and I will continue to work towards making this article NPOV, properly sourced, and useful to those seeking an accurate record of the hysterics that so often follows catastrophe. Cheers. -- BD2412 talk 00:53, 14 September 2005 (UTC)

Thank you for clearing that up for me. Ryulong 20:31, 29 June 2006 (UTC)

Remember to take the photos. Thanxs! =D Jumping cheese Contact 21:59, 12 July 2006 (UTC)

Great! Upload the pics and make the page look better. =D Jumping cheese Contact 03:12, 14 July 2006 (UTC)

[edit] Modern geocentrism

Did you know that User:Lucaas considers you as being on his side in an ongoing content dispute at Modern geocentrism: [1]? I thought you should be aware of this. --LambiamTalk 23:46, 6 September 2006 (UTC)

No, I didn't know that he considered on his side of the dispute. I knew nothing about it until you directed me. I assure you that I had done nothing more than fixed a spelling error of his. Besselfunctions 04:14, 7 September 2006 (UTC)

[edit] Total re-write of the main Physics page is in progess

You might like to join us at Physics/wip where a total re-write of the main Physics page is in progess. At present we're discussing the lead paragraphs for the new version, and how Physics should be defined. I've posted here because you are on the Physics Project participant list. --MichaelMaggs 08:04, 11 October 2006 (UTC)

[edit] Orphaned fair use image (Image:RPI-seal-t.gif)

Thanks for uploading Image:RPI-seal-t.gif. I notice the 'image' page currently specifies that the image is unlicensed for use on Wikipedia and may only be used on Wikipedia under a claim of fair use. However, the image is currently orphaned, meaning that it is not used in any articles on Wikipedia. If the image was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that images for which a replacement could be created are not acceptable under fair use (see our fair use policy).

If you have uploaded other unlicensed media, please check whether they're used in any articles or not. 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 fair use images not used in any articles will be deleted after seven days, as described on criteria for speedy deletion. Thank you.

[edit] LOL my bad

LOL I can't believe I wrote November, I was reading the sentence before it. hehe thanks! Fedayee 21:37, 31 December 2006 (UTC)

[edit] RSE

Yeah, I took RSE off the template. I was surprised they even had a page, and it needs to be expanded. Otherwise, I am fairly pleased with it. Danski14 17:07, 8 January 2007 (UTC)

[edit] Quick CSD comment

Heya Besselfunctions, and thanks for doing some patrolling for bad pages. Just wanted to let you know that H1 was a disambig page and an IP replaced it with a nn-band description, so i reverted and declined the speedy. It's helpful to check the page's edit history to make sure it needs to be deleted and not reverted. Thanks and keep up the good work! ~Eliz81(C) 18:22, 23 November 2007 (UTC)

[edit] Recent changes to bicycle and bicycle performance articles

Although the actual change to the text of bicycle appears benign, I believe the explanation you gave is mistaken: "the drag would increase linearly with speed, since the drag is proportional to the square of the speed". Proportionality to the square of an input variable is one of the most common examples given for a nonlinear relationship.

I reverted the change to the text of bicycle performance "aerodynamic drag, which increases linearly with speed" because drag increases with the square of speed, and that is not a linear relationship. -AndrewDressel (talk) 16:18, 26 December 2007 (UTC)

I don't quite understand what the problem was. Drag is quadratic in speed, so it increases linearly with speed. Power is cubic in the speed, so it would increase quadratically. The source says that the drag is ρAV2, so when one speaks of the drag's increase with speed, not the drag itself, why is it not the derivative of that expression, i.e. the drag increases linearly with speed? Besselfunctions (talk) 20:26, 26 December 2007 (UTC) (Retrieved from "http://en.wikipedia.org/wiki/User_talk:AndrewDressel")
Ah, now I see. It appears to be just an issue of semantics, not mathematics. You are interpreting "is quadratic in" to be equivalent to "increases linearly with". However, the cited source, in discussing air drag explains that "the force exerted by the drag is seen to increase as the square of the velocity." The author does not use the derivative of the derived expression to describe how a change in velocity translates into a change in drag. Instead, he uses the original, quadratic relationship. For example: doubling speed results in a four fold increase in drag, even though the derivative of the drag with respect to velocity is proportional to the velocity and not its square. -AndrewDressel (talk) 20:55, 26 December 2007 (UTC)
