Sources
editHello, I'm DVdm. I noticed that you made a change to an article, Special relativity, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so! If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. - DVdm (talk) 13:51, 7 September 2016 (UTC)
Hello, I'm DVdm. Your recent edit to the page Gravitational potential appears to have added incorrect information, so I have removed it for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. - DVdm (talk) 13:59, 3 October 2016 (UTC)
- Note: as you see, there are 3 references at Gravitational potential#Mathematical form, with direct pointers to the cited pages in the sources, that support the current content. Your edit essentially destroyed that. Before you make changes to article content, please verify first whether your changes remain or are consistent with the context. Thanks. - DVdm (talk) 14:11, 3 October 2016 (UTC)

editAbout the image of the SR NOR latch
editHello, Goodphy! I think there is a mistake in the image you've added to the Flip-flop article: Should not the description of the last state reads (R,S) = (1,1) instead of (R,S) = (0,1)? Abd.nh (talk) 07:54, 22 December 2020 (UTC)

Ring theory pages
editHello, Goodphy! I know you mean well, but it really isn't helpful to add things like the meaning of the symbol 0 and the identity 0a=a to pages about other ring theory topics. These things will just make an article harder to read, because the main points will be surrounded by all these other statements that readers of the page likely already know. If you want to reply, you can reply here on this page, since I am temporarily watching it. Or you can simply delete my message after reading.

I'm pretty sure you've got your up and down, or concave and convex, reversed. Can you say what sources support? Dicklyon (talk) 02:59, 23 March 2021 (UTC)
Nevermind; I see the Hamming ref and some others agree with you. Dicklyon (talk) 03:02, 23 March 2021 (UTC)
Disambiguation link notification for July 19
editHi. Thank you for your recent edits. An automated process has detected that when you recently edited Scalar (mathematics), you added a link pointing to the disambiguation page Field. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)
It's OK to remove this message. Also, to stop receiving these messages, follow these opt-out instructions. Thanks, DPL bot (talk) 05:57, 19 July 2021 (UTC)

December 2022
editHello. In a recent edit to the page Port (circuit theory), you changed one or more words or styles from one national variety of English to another. Because Wikipedia has readers from all over the world, our policy is to respect national varieties of English in Wikipedia articles.
For a subject exclusively related to the United Kingdom (for example, a famous British person), use British English. For something related to the United States in the same way, use American English. For something related to another English-speaking country, such as Canada, Australia, New Zealand, Ireland, India, or Pakistan use the variety of English used there. For an international topic, use the form of English that the original author of the article used.
In view of that, please don't change articles from one version of English to another, even if you don't normally use the version in which the article is written. Respect other people's versions of English. They, in turn, should respect yours. Other general guidelines on how Wikipedia articles are written can be found in the Manual of Style. If you have any questions about this, you can ask me on my talk page or visit the help desk. Thank you. SpinningSpark 23:06, 11 December 2022 (UTC)

editIt appears that you have been canvassing—leaving messages on a biased choice of users' talk pages to notify them of an ongoing community decision, debate, or vote—in order to influence Extreme ultraviolet lithography. While friendly notices are allowed, they should be limited and nonpartisan in distribution and should reflect a neutral point of view. Please do not post notices which are indiscriminately cross-posted, which espouse a certain point of view or side of a debate, or which are selectively sent only to those who are believed to hold the same opinion as you. Remember to respect Wikipedia's principle of consensus-building by allowing decisions to reflect the prevailing opinion among the community at large. Thank you. — Diannaa (talk) 14:19, 20 July 2023 (UTC)
Two minor optics quibbles
editHi Goodphy. I've seen many of your recent edits to optics articles, and noticed two things I wanted to point out to you. This edit has both of them.
- A lens has only one aperture stop, and the entrance and exit pupils are images of it. It is misleading to say that the entrance pupil is "the image of an aperture". It is the image of the aperture stop. A lens can have many apertures within it, but there is only one aperture stop, and only one entrance pupil.
- It isn't really necessary to emphasize that the image formed at infinity is to the right or to the left. It is neither. When we say that a lens forms an image at infinity this is the same as saying it does not form an image anywhere. The rays are parallel; no image is formed at any finite distance but you can treat the parallel rays as if they formed either a real image at +infinity or a virtual image at -infinity; it's all the same, physically.
Srleffler (talk) 19:03, 19 August 2023 (UTC)
- Hi Srleffler. Thank you to provide a good advice. For the first advice (an aperture to the aperture stop), I accepted your advice. For the second advice, I still believe that the location of pupils at the left or the right (even if they are at infinity) is better to be mentioned for straightforward visual understanding of telecentricity. Your point may be obvious for you, but I believe it is not for others, especially newcomers in optics. Goodphy (talk) 08:14, 20 August 2023 (UTC)
- I understand your point. I might try to find wording that avoids describing it as an "image at infinity" altogether, if I can do so without making it more confusing.--Srleffler (talk) 17:59, 20 August 2023 (UTC)

Nomination of Proofs of elementary ring properties for deletion

Updating images
editHi Goodphy. I noticed that you uploaded several different image files while refining the image for Entrance pupil, eg File:Entrance pupil - 3, 2024-07-18.png and File:Entrance pupil - 4, 2024-07-18.png. You don't have to create a new image page with a new name each time you want to make a minor update. If you go to the image's page on Commons (eg Entrance_pupil_-_3,_2024-07-18.png) and scroll down to the "File History" section, there is a link there that says "Upload a new version of this file". The new file you upload will replace the old one and articles that are using the image will automatically use the new version. -- Srleffler (talk) 05:16, 21 July 2024 (UTC)
- Hi Srleffler.
- Thank you to find a way of a Wikipedia feature of updating existing pictures. This is what I had searched for but I was not reaching it. I will remember "Wikimedia Commons" as a platform my contributions toward Wikipedia may be able to be updated. Goodphy (talk) 01:23, 23 July 2024 (UTC)
Nice work on that diagram by the way.--Srleffler (talk) 05:17, 21 July 2024 (UTC)
