Welcome

Hello and welcome to Wikipedia! We appreciate encyclopedic contributions, but some of your recent edits, such as the ones to the page Laplace operator, do not conform to our policies. For more information on this, see Wikipedia's policies on vandalism and limits on acceptable additions. If you'd like to experiment with the wiki's syntax, please do so in the "sandbox" rather than in articles.

If you still have questions, there is a new contributor's help page, or you can write   below this message along with a question and someone will be along to answer it shortly. You may also find the following pages useful for a general introduction to Wikipedia. I hope you enjoy editing and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. Feel free to write a note on the bottom of my talk page if you want to get in touch with me. Again, welcome! Sławomir Biały (talk) 10:48, 27 July 2010 (UTC)

Hello, Thank you for your comment. You are right. I made a correction. While reading one of the articles I've found a mistake. I tried to correct it. Do you think that correction is wrong or I did it in a way not satisfying contributions of wikipedia? Zhanna leuven (talk) 15:29, 27 July 2010 (UTC)Zhanna leuven


 * The way Wikipedia works is summed up in Bold, Revert, Discuss. If you see a change that will improve the encyclopedia, be WP:BOLD and make it - as you did, good. If someone then reverts it, don't revert back, which leads to WP:Edit warring - and you didn't, good again. The next step is to discuss on the article talk page with the user who reverted, and try to reach WP:Consensus; failing consensus, use the WP:Dispute resolution process. In this case, the user who reverted you has posted a note on the article talk page; and I have added a comment to that to say that his usage is inconsistent with the article Spherical coordinate system, where &phi; is used for azimuth. So watch Talk:Laplace operator for his reply, or leave a mesage on his talk page if you like. Regards, JohnCD (talk) 16:16, 27 July 2010 (UTC)
 * I spoke too soon: reading on in Spherical coordinate system, I see it says:
 * "However, some authors (including mathematicians) use φ for inclination (or elevation) and θ for azimuth, which 'provides a logical extension of the usual polar coordinates notation.' Some authors may also list the azimuth before the inclination (or elevation), and/or use ρ instead of r for radial distance."
 * So it's another case of "standards are wonderful, you can't have too many." Regards, JohnCD (talk) 16:36, 27 July 2010 (UTC)


 * I've read carefully their comments on the edit page of Laplacian article. What I think, is that to me it looks strange that due to different schools in Europe and USA we are using different designation for the same parameters. I think it is of outermost importance that all the articles comply to each other. And if the spherical coordinates we define phi as azimuth angle and tetta as a polar, then it must be the same in all the articles. Wikipedia doesn't have borders. It is made for educating people. In some cases children studying it school. And believe me, sometimes they do not have idea to check the references and formulas. I guess in that case it would be better to correct the formula, changing tetta and phi. I can't understand when stubbornness stands between knowledge and truth.
