Stern-Gerlach experiment lifted

Hi,

I noticed that your edit to Stern-Gerlach experiment seems to use the text of [1]. The Stern-Gerlach experiment is definitely something we need an article on; I only noticed because I was planning on writing an article on it myself! But it can give Wikipedia some legal problems if we use copyrighted text without permission. The policies are on Wikipedia:Copyrights, if you're interested. I hope you're interested in contributing to Wikipedia; let me know if you have any questions. -- Creidieki 02:46, 12 Sep 2004 (UTC)

Apologies

I would like to express my sincere apologies pertaining to the Stern-Gerlach experiment. What I tried to do is to cut and paste from that website and then edit it throughly with whatever I know. Unfortunately, when I was done uploading halfway, my internet connection failed. I will try to prevent such mistakes in future and appreciate your comment. I do not want to get Wikipedia into any legal problems.

• I don't imagine it will cause any real problems. At worst, if the owner of a site complains, the administrators can delete the text. I wrote the beginning of an article, but it could use any improvements you can give it. I hope you enjoy Wikipedia; if you have any questions or problems, feel free to leave notes on my talk page. -- Creidieki 20:55, 25 Sep 2004 (UTC)

Image Tagging Image:Carbene strsp.png

This media may be deleted.

Thanks for uploading Image:Carbene strsp.png. 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-self}} 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 {{Non-free fair use in|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. Shyam ^(T/C) 17:05, 3 March 2006 (UTC)

Request for edit summary

When editing an article on Wikipedia there is a small field labelled "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.

When you leave the edit summary blank, some of your edits could be mistaken for vandalism and may be reverted, so please always briefly summarize your edits, especially when you are making subtle but important changes, like changing dates or numbers. Thank you.

Noted

Thank you for your comment Oleg Alexandrov. I'll keep that in mind.

Apollonius' theorem

I overwrote your version of the article, as it is not right. There is no way that $m$ and $n$ be any numbers, then it would follow that the segment $AD$ is perpendicular to the side $BC$. Wonder what you think. You can reply here, Thanks. Oleg Alexandrov (talk) 00:46, 2 April 2006 (UTC)

Re: Apollonius' theorem

Thank you for pointing out the blatant error in my article and attempting to correct it. m and n cannot be any two numbers; the theorem seems terribly wrong then. I must have been half-asleep when I wrote it :)

However, by attempting to correct it, there is a loss of generalisation; you have considered a special case of the Apollonius' theorem where $m=n(=1)$.

My version of the Apollonius theorem can be corrected by adding the line "D divides BC in the ratio m:n". m and n are obviously not any two numbers, but two positive real numbers that correspond to the ratio BC is divided by D. I'm not sure if the theorem holds when D is a point on BC extended. I shall hence attempt to prove it and post the result shortly. I don't like the diagram you took from mathworld very much, and I shall also attempt to draw a clearer diagram with Inkscape* to replace it.

(*) I'm not very good with Inkscape, and I'm just wondering which vector drawing applications you use.

I did not know how to fix the article, that's why I overwrote it. Feel free to replace my ugly picture. :) Oleg Alexandrov (talk) 08:37, 2 April 2006 (UTC)

Inskspace is a good program. I use Matlab mostly, but for such a thing Inkscape is better. Oleg Alexandrov (talk) 08:38, 2 April 2006 (UTC)

Thank you for the corrections and the picture. I have one suggestion though. It would be nice if the picture is smaller in size, say as what is on the right, while the letters are bigger and the lines thicker. Also, I am not sure about the need for (m) and (n) labels, and especially for the (m+n) label, as I think the length of that side is not propoportional by that quantity compared to the other sides.

You can reply here, I will keep your talk page on my watchlist. Oleg Alexandrov (talk) 22:28, 2 April 2006 (UTC)

Yes, it's a good suggestion. I thought the image was too big myself. In accordance with your suggestion, I made the text bold and made the lines thicker to improve visibility, resized it to 300px (a little larger than you suggested) so that it's compact and visible at the same time. If you feel it should be smaller, feel free to resize it. lol about the (m), (n) and (m+n) labels! They aren't even remotely supposed to indicate lengths of sides. They're supposed to indicate which number to multiply each of the sides with; I thought it would be helpful in understanding Apollonius' theorem. Anyway, since you think the labels are confusing, I changed them to (times m), (times n) and (times (m+n)). If you still think they're confusing/ unnecessary, feel free to take the image down and manually erase those labels with a graphics suite like GIMP. I'm not sure I will be able to respond quickly for the next one week or so, as I'm busy in real life; so please excuse my late replies. --ram_einstein 08:22, 3 April 2006 (UTC)

By the way, do you think the article is a stub? Maybe we should remove the label, as it's complete except for the proof? I'll work out put up the proof as soon as I can. --ram_einstein 08:25, 3 April 2006 (UTC)

I think it is not a stub. :) Oleg Alexandrov (talk) 02:24, 4 April 2006 (UTC)

Rmeoved stub tag. ram_einstein 06:24, 4 April 2006 (UTC)

Categorising your user page

Sorry for mucking around with your user page for so long, the {{wronguser}} template was hard to find, ie. they didn't reference it as being part of the category. No major dramas, I was just sorting the main unsupported titles category and came across it, will know for next time :). Ansell 23:53, 20 April 2006 (UTC)
