Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, your addition of one or more external links to the page Elastic collision has been reverted. Your edit here to Elastic collision was reverted by an automated bot that attempts to remove links which are discouraged per our external links guideline. The external link(s) you added or changed (http://peruzzic.wordpress.com/downloads/2dcollision-jfm.pdf) is/are on my list of links to remove and probably shouldn't be included in Wikipedia. If you were trying to insert an external link that does comply with our policies and guidelines, then please accept my creator's apologies and feel free to undo the bot's revert. However, if the link does not comply with our policies and guidelines, but your edit included other, constructive, changes to the article, feel free to make those changes again without re-adding the link. Please read Wikipedia's external links guideline for more information, and consult my list of frequently-reverted sites. For more information about me, see my FAQ page. Thanks! --XLinkBot (talk) 16:32, 14 October 2016 (UTC)

Hello, I'm DVdm. I wanted to let you know that I removed one or more external links you added to Elastic collision because they seemed inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page or take a look at our guidelines about links. Thanks. DVdm (talk) 08:07, 15 October 2016 (UTC)

Hi DVdm,

yes, my article would not be suitable for encyclopedia entry. But you did find suitable Mr. W. Craver's approach: a reader must link his website to get a couple of pictures necessary to understand impact angles. Unfortunately, there are entries on which secondary sources exhibit a consensus and other entries on which they are less assertive, as on ``Elastic collision``. Did you ever ask Professor Lewin on two-dimensional collision? Since Compton's calculation (but his electron was at rest!), the current research does not want to deal with such an issue anymore. On the other hand, secondary sources (you rely upon) are more interested in preparing new editions rather than in investigating such theoretical issues. My attempt, I'm aware, needs time to build a consensus on this issue. For this reason I preferred the “external link” approach, as a more viable solution, rather then editing the ``Two-dimensional`` section. But, I understood, my blog is in a website (wordpress) which belongs to your black list. This, frankly speaking, surprise me very much. My blog at https:\\peruzzic.wordpress.com is completely free, it pays no fees for advertisement, it's 9-year old with an insignificant number of contacts ... So, I do not know what to do. I have two websites, www.myphysics.it and .eu, they simply redirect to access my blog. Pls, only one (out of the two) link you removed is correct i.e. open my pdf, this one: https:\\peruzzic.files.wordpress.com/2007/12/2dcollision19-jfm.pdf. Many thanks for your understanding (sorry, my skill as editor is at the moment very limited). Clay4205 (talk) 17:44, 16 October 2016 (UTC)
