Hello and welcome to Wikipedia. When you add content to talk pages and Wikipedia pages that have open discussion (but never when editing articles), please be sure to sign your posts. There are two ways to do this. Either:
- Add four tildes ( ~~~~ ) at the end of your comment; or
- With the cursor positioned at the end of your comment, click on the signature button ( or ) located above the edit window.
This will automatically insert a signature with your username or IP address and the time you posted the comment. This information is necessary to allow other editors to easily see who wrote what and when.

Hello. Your contributions to Wikipedia have been analyzed and it seems that this new Wikiproject would be interesting to you. I hope you can contribute to it by expanding the main page and later start editing the articles in its scope. Make sure to check out the Talk page for more information! Cheers
Hello, I'm JohnBlackburne. An edit that you recently made to Special relativity seemed to be a test and has been removed. If you want more practice editing, please use the sandbox. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks! JohnBlackburnewordsdeeds 14:54, 14 January 2015 (UTC)
Nuclear fission and WP:FAC
Please stop trying to nominate this article for featured article status. You're doing it wrong, for a start, and more importantly the article is so far away from featured article status that there's no point in trying. Paragraph after paragraph lacks citations, for instance. Please read the featured article criteria before nominating articles. You may want to bring a less challenging article through the good article process and then peer review before trying FAC, rather than launching into FAC with no prior preparation.

Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Jyotirlinga, you added a link pointing to the disambiguation page Parli (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ • Join us at the DPL WikiProject.
Alkenes are not necessarily insoluble in water
Before making such edits, you might talk to your teacher or a chemistry professional about the wide range of properties of alkenes. Even ethylene has an appreciable aqueous solubility, unsaturated alcohols and carboxylic acids especially so. Just ask around, lots of people here that can give advice about basic chem. --Smokefoot (talk) 14:41, 10 October 2015 (UTC)
Edits to Geometric Optics
- Refraction is governed by the change in index of refraction, not density. Like you, I am not satisfied with the sentence "Refraction occurs when light travels through an area of space that has a changing index of refraction." The dual mention of a "refraction" makes the definition circular.
- refraction occurs even when the change in material properties is gradual, as in refraction around a planetary atmosphere
- "is the phenomenon of light in which" was a bit wordy for my tastes (though others might disagree)--Guy vandegrift (talk) 13:44, 25 October 2015 (UTC)
Hi Mahusha. I reverted several of your edits today, in which you deleted red links from articles. Do not arbitrarily remove links just because they are red. See Wikipedia:Red link for information on red links and why they are important.--Srleffler (talk) 23:18, 25 October 2015 (UTC)
You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
