User talk:BoP

Hello BoP, welcome to Wikipedia.

You might find these links helpful: How to edit a page, How to write a great article, Naming conventions, Manual of Style. You should read our policies at some point too.

If you have any questions, see the help pages, add a question to the Help desk or (if you want a broader audience) the village pump, or ask me on my talk page. I hope you enjoy editing here and being a Wikipedian!

You can introduce yourself on the new users page.
You can find lots more information, including open tasks and daily tips, at the Community Portal.
You can sign your name using four tildes, like this: ~~~~.
Before saving a page, it's a good idea to use the Show preview button to review your edits. Also, consider writing a summary for each edit.
The Tutorial is a great way to learn the basics in a more perspicuous fashion.

Again, welcome! Chris Roy 01:26, 3 May 2004 (UTC)[reply]

Category:British Hills by Height

I saw you comments in Wikipedia:Village pump (proposals)#Automatically Generating Category-Lists from Categories and realised you may be interested in the categorys Category:British Hills by Height and Category:Mountains by Elevation (km). These appear (in my opinion) to be liked by the actual mountain contributors. Can I tempt you to make a contribution/comment here to save (or otherwise) these pages?: Wikipedia:Categories_for_deletion/Log/2005 September 1#Category:Mountains_by_Elevation_(km) and its subcategories

Self-phase modulation

Hi BoP, I just did a rewrite of self-phase modulation, because I think the derivation you added isn't correct. In particular the frequency shift doesn't seem right. Please take a look and let me know if I'm missing something. --Bob Mellish 00:58, 4 November 2005 (UTC) - I agree that the new derivation is much more generic and looks quite O.K. to me! (I have only corrected the inst. phase $\phi \rightarrow \phi (t)$ )--BoP 08:24, 27 December 2005 (UTC)[reply]

Numerical aperture and focal length

Hi BoP. In Numerical aperture you wrote "The f-number therefore is independent of the object distance and is directly related with the focal length, while the numerical aperture is dependent on the particular imaging geometry." This is not really true. The f-number (as defined in the article) describes the imaging properties of the lens only when the object or the image is at infinity. It is no more independent of the imaging geometry than numerical aperture is. To describe imaging with the object and image a finite distance from the lens, one must use the "effective f-number", which is defined slightly differently. (I don't remember the formula offhand, and the book where I have it is at work.) Photographers simply ignore this. One could say that the use of f-number in photography involves an approximation, that the object distance is much greater than the image distance. I would expect that this approximation would become noticeably inadequate for closeups and macro photography, but unless someone is dealing with exposure very quantitatively one still might not notice.--Srleffler 00:47, 4 March 2007 (UTC) Agreed - the earlier definition was a bit misleading - The current version seems to take care of that! --BoP (talk) 21:44, 13 December 2007 (UTC)[reply]

Proposed deletion of Process window

The article Process window has been proposed for deletion because of the following concern:

Pure WP:OR and an essay. Either to be salvaged with relevant context and citations or to be deleted.

While all constructive contributions to Wikipedia are appreciated, content or articles may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the {{proposed deletion/dated}} notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the article to address the issues raised. Removing {{proposed deletion/dated}} will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

ArbCom elections are now open!

Hi,
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.

Please claim your upload(s): File:Kerr-lens Modelocking.png

Hi, This image was seemingly uploaded prior to current image polices, Thank you.

However, as part of ongoing efforts to ensure all media on English Wikipedia is correctly licensed and attributed it would be appreciated if you were able to confirm, that it was your own work, by marking it as {{own}}, amending the {{information}} added by a third party, and by changing the license to an appropriate "self" variant. You can also add |claimed=yes to the {{media by uploader}} tag if it is present to indicate that you've acknowledged the image, and license shown (and updated the {{information}} where appropriate).

This will assist those reviewing the many many "free" images on commons that have not yet been transfered to Commons. Sfan00 IMG (talk) 15:18, 4 June 2016 (UTC)[reply]

Disambiguation link notification for September 14

Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Maskless lithography, you added a link pointing to the disambiguation page PCB (check to confirm | fix with Dab solver). 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.)
