Re: Faraday effect diagram, you're right about the direction of rotation (I checked in Hecht). I drew it that way because it was easier, not for any good reason. Actually I'm not too happy with how the diagram came out (I don't think it shows the rotation very well),so I'll try altering it and see how it looks. Oh, and welcome to Wikipedia! -- DrBob 18:59, 12 Mar 2004 (UTC)
Thanks, this is a lot of fun for me. I like the look of the diagram, especially the color and shading. I would have an easier time if it could show the direction of propagation. For my money, showing the sense of the current flow, rather than the coil itself, as Hecht does, would make it easier to apply the right hand rule to get the B field. Am I right in thinking that the polarizers Hecht shows are essential to the isolator design? That the 45 degree rotation (he implies) means that the reflected wave will be rotated 90 degrees and thus be blocked by the entrance polarizer? The microwave isolator also includes an absorber for the relected wave. In the optical isolator is the dissipation achieved with a dichroic polarizer? AJim 21:13, 12 Mar 2004 (UTC)
- I'll see what I can do with adding the propagation direction to the diagram - I might make it more like Hecht's diagram to make the polarization direction clearer. I think the coil would obscure things too much, though. Yes, polarizers are necessary for optical isolators, usually polarizing beam splitters on either end. They have adjustments to fiddle with the magnet spacing to get exactly 45° rotation at the wavelength you want. -- DrBob 17:56, 15 Mar 2004 (UTC)
It does not make so pretty a picture, but what I drew to check myself was an end-on view, looking into the source, no coil, just I circulating ccw. The right-hand rule then said that B was in the propagation direction. Then the rotation had to be ccw also from the definition. Perhaps the end-on picture might be a supplement? There is something mnemonic about the current and the rotation being in the same sense anyway. I found the coil distracting myself. I think there is a potential for confusion by introducing the coil helix sense. The real fun, for me, is that I now understand Faraday isolators better. Thank you for that. AJim 22:57, 16 Mar 2004 (UTC)
Thanks for the compliment :) And you're right, that Sellmeier graph should be micrometres rather than nanometres along the x-axis. I've uploaded a corrected version. Thanks for spotting that. -- DrBob 16:15, 18 Mar 2004 (UTC)
Tip (re [[wild pointer). If you're writing code blocks, you don't need to use pre and nowiki wrappers. If you start a line with a single, leading space, you get the effect (edit this page to see the markup)
int main(void) { return 0; }
which has the advantage of looking much easier to read in the markup. By the way, K&R-style function declarations might look nice, but we might want to stick to ANSI C ;)

Pageboy
[edit]At Page Boy (which I've renamed to the apparently more standard Pageboy), you say:
- The Page Boy is a hair style named after a drawing of a woman dressed as an English page boy.
I'm wondering what your source for this is. Do you mean a particular drawing by a particular artist? Also, as far as I know, the style was actually popularized in the 1920s by the actress Louise Brooks. I would expand the article a bit, but I'd like to drop the reference to the drawing unless there's a source. - dcljr 18:40, 23 Mar 2005 (UTC)
Hi there! You seem to be the guy to ask. Can you do anything with Cotton effect and with Optical rotatory dispersion? I have just added them as stubs. Jeff Knaggs|Talk 11:08, 20 October 2005 (UTC)
Deuterium arc lamp update
[edit]Hello, I've justed started editing Wikipedia and I've started by expanding the stub on deuterium arc lighting. I've noticed that you have made some contributions to the Xenon arc lamp page and I was wondering if you might be able to give me some advice on things I could add, change, etc. Thanks!

Sheeran
[edit]I deleted the reference on the Sheeran page in response to a single purpose account linked to the book's publisher who was spamming links to a website promoting the book. If I remember correctly, the link is pretty promotional, but if you think it should be in, it's unlikely I'll visit the page or try to delete it again. --Steven J. Anderson (talk) 08:08, 24 December 2008 (UTC)
- Maybe I am confused. I think what was removed and put back was a simple citation of the book, not the link you mention. In fact, I think the link was, and still is, there. I agree the link is pretty promotional. I think the book ought to be cited as the source of the information about Sheeran. I do not think referencing the book gives undue weight. --AJim (talk) 08:26, 24 December 2008 (UTC)
- Without looking closely at what I did, I'll say you're probably right. I was kinda ticked at the SPA when I was reverting him and might have gotten a little over-exuberant. Apologies. --Steven J. Anderson (talk) 01:29, 25 December 2008 (UTC)
Re: question about "fix structure"
[edit]Oh my gosh, a user from 2004? I'm not worthy... :)
I've only seen section headings with 2d level, 3d level and so forth, not 1st level. I've read plenty of Wikipedia articles, and that's what I always see. When I saw your article, I said to myself "This doesn't look right" and I changed it. I did not intend to change anything substantive, only to reduce 1st-level headings to 2d-level, and 2d-level headings to 3d-level. I hope I did more good than harm.

Hi. I saw your notes on Talk:Cary Instruments. I started the article, and wrote from my experiences working in a lab that used a Cary-60 (we also had a Beckman Model-E, but that's another story). It sounds like you know more about these instruments than I do, and I encourage you to improve the article, especially if you can find reliable, citable references. -- RoySmith (talk) 20:42, 6 February 2009 (UTC)
Proposed deletion of Unittest
[edit]The article Unittest has been proposed for deletion because of the following concern:
- Unsourced and lack of context
While all 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 {{dated prod}}
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 {{dated prod}}
will stop the Proposed Deletion process, but other deletion processes exist. The Speedy Deletion process can result in deletion without discussion, and Articles for Deletion allows discussion to reach consensus for deletion. Eeekster (talk) 04:59, 14 September 2009 (UTC)
Speedy deletion nomination of Gunnar Berndtson
[edit]A tag has been placed on Gunnar Berndtson requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about a person or group of people, but it does not indicate how or why the subject is important or significant: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, such articles may be deleted at any time. Please see the guidelines for what is generally accepted as notable, as well as our subject-specific notability guideline for biographies. You may also wish to consider using a Wizard to help you create articles - see the Article Wizard.
If you think that this notice was placed here in error, you may contest the deletion by adding {{hangon}}
to the top of the page that has been nominated for deletion (just below the existing speedy deletion or "db" tag), coupled with adding a note on the talk page explaining your position, but be aware that once tagged for speedy deletion, if the page meets the criterion, it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the page that would render it more in conformance with Wikipedia's policies and guidelines. Lastly, please note that if the page does get deleted, you can contact one of these admins to request that they userfy the page or have a copy emailed to you.

Artificial altitude
[edit]Hi, AJim. I went to the pages you linked to at the See Also section of Altitude training. None of the applications of those technologies involved people breathing the nitrogen-enriched air.

Book references at Switching circuit theory
[edit]Thanks! --Wtshymanski (talk) 18:17, 23 June 2011 (UTC)
Hi there. Is there a chance your group can get a picture of the Fessenden hydrophone you are working on? One picture would be worth many words in the article. --Wtshymanski (talk) 17:59, 28 June 2011 (UTC)
- At the present time the supposed transducer is housed in a vertical cylinder installed near the midline on the inner hull in the forward magazines section of the ship. Access is difficult. The cylinder has a mechanism on top that appears to allow height adjustment of something inside. This cylinder has not been opened, to anyone's knowledge, in many years. It is not clear if the top of the cylinder is above the water line. We are very curious. We are proceeding cautiously. We have no current photo.
- In the meantime, there appears to be a historic photo available from the NOAA Photo Library: Reginald Fessenden and his electric oscillator. From the NOAA Library about page it appears that this photo is available for use. The photo shows an object of the approximate size and shape expected from the patent description and the article that this picture is used in. My problem is that I do not have the time to read and try to cope with the current Wikipedia image upload rules. If you are familiar with the rules, and can navigate them(!), and think the image really is available, please go ahead and add it. The photo caption says the source is: "Submarine Signaling," Scientific American Supplement, No. 2071, pp. 168-170, Sept. 11, 1915.
- By the way, the NOAA article is an excellent source for other references. The article also includes, for instance, a transcript of the Report of Captain J.H. Quinan of the U.S.R.C Miami on the sea trials conducted on 27 April 1914, as reported in the Hydrographic Office Bulletin of May 13, 1914.
- The key patent, which describes the construction of the transducer, is U.S. patent 1,167,366, "Dynamo-Electric Machinery" – issued 4 January, 1916 (original application filed on 29 Jan 1913). It would also be useful to add Figure 1 from the patent to the article, or possibly a cleaned-up version. Again, I am not prepared to cope with this. However, the operation section of the current article has not yet captured some of the key design details, such as the opposed armature windings used to drive the copper tube in the opposite air gaps, and the claimed advantages of this design. It would be helpful to show the field orientations to help make it clear that the opposed windings ultimately produce forces that add. I can confirm that the net inductance of the two armature windings nearly cancels (< 1 mH, compared to 670 mH for the field winding, which is about the same resistance and apparent wire size).

Circular polarization
[edit]My understanding is that "mixed polarization" as described above is not allowed by the FCC -- only either Horizontal, Circular or Elliptical. Slant polarization, with H and V at different powers but in phase, is not allowed for FM or TV. See: CFR 47 § 73.316. I believe the entire paragraph should be removed.

[edit]In a recent edit, 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, or New Zealand, use the variety of English used there. For an international topic, use the form of English that the original author 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.
