Please do not add inappropriate external links to Wikipedia, as you did to Special relativity. Wikipedia is not a collection of links, nor should it be used for advertising or promotion. Inappropriate links include (but are not limited to) links to personal web sites, links to web sites with which you are affiliated, and links that attract visitors to a web site or promote a product. See the external links guideline and spam guideline for further explanations. Since Wikipedia uses the nofollow attribute value, its external links are disregarded by some search engines, including Google. If you feel the link should be added to the article, please discuss it on the article's talk page rather than re-adding it. Thank you. Never, ever, add executable download links to a wikipedia article; there's no way to police that these aren't simply malware / viruses / ... Quaeler (talk) 09:58, 5 December 2008 (UTC)

Please stop. If you continue to use disruptive or hard to read formatting, as you did in Mass in special relativity, you will be blocked from editing Wikipedia. Please take a look at how article structure is generally done with articles at wikipedia. Adding a PDF link in the middle of an article with some verbiage like 'For more info, read this external link' is not acceptable. Thanks. Quaeler (talk) 10:01, 5 December 2008 (UTC)
