Hi. We appreciate very much your contributions to the Citizendium. I was hoping you could help clear up a matter about the images you recently uploaded. They are lacking clear copyright and source data and need to have it as soon as practicable to avoid deletion. To fix the problem, please review the images you uploaded (click on "my contributions" at the upper-right to re-trace your steps or see the links I added) in light of Images Help—Copyrights. If you need additional help, just ask a constable or leave a message on my talk page and I'll be more than glad to assist. —Stephen Ewen 20:43, 22 April 2007 (CDT)

Hi David. Just copy this text

OK David, I will look at your ideal gas law. I must add that I'm very glad that there is another scientist active in CZ. I was afraid I was the only one (outside biology, that is).

I see that you worked at Duke. I spent a year there. Long time ago in the Chemistry department (with Donald Chesnut). I have very good memories of that year, I really liked living and working in the US. --Paul Wormer 03:15, 4 October 2007 (CDT)


Hi David, i made the following edit on your behalf to kick off the ToApprove process on the Van_der_Waals_equation article. I hope that is OK Chris Day (talk) 15:02, 4 October 2007 (CDT)

David, I was getting ready to do the approval on Van der Waals equation when I noticed ther ehave been several more edits since your approval date. As it is, I can only approve the date that is in the green box, so I will wait till later tonight to approve. If you want to include these edits, just change the date and version in the box. If not, you don't have to do anything and I will approve the version that you have marked. Thanks.. Matt Innis (Talk) 18:30, 8 October 2007 (CDT)

Congratulations on your first Approval! I did change the date for you and approved the extra edits as you stated on my talk page. When you want to find the latest version, follow these steps: 1)click on the history tab, 2)click on 'compare selected version...' button, 3)click on the 'Revision as of [date]' above the previous diff, 4)click on 'newer revision' under the article title, 5)copy the address from the address bar.. and you got it! It is a long way around. If you ever find a better way, do let me know! Matt Innis (Talk) 18:57, 9 October 2007 (CDT)

NMR article?

Hi David, I read on your bio that NMR seems to be a topic which you are familiar with. So, I was wondering if perhaps you may have plans on writing an article on Nuclear magnetic resonance in the future. Anyway, I guess the reason I'm asking is that an article I started on open loop control links to that :-) Just a thought. Thanks. Hendra I. Nurdin 16:28, 6 October 2007 (CDT)

Hi David, I saw your message on my talkpage and totally understand what you're saying. There are also plenty of articles I would like to write, but unfortunately I am unable to find the time to do the research and retrieve the necessary books and papers. So far, I've mostly written about things which I know quite well or have often used in my work and thus can be called off the top of my head or from notes I've made. CZ has yet to reach critical mass :-) Hendra I. Nurdin 16:06, 8 October 2007 (CDT)

Virus template

I think there already is a model for this that has been made; for proteins I think. We should be able to copy that and just change the verbage. --Robert W King 16:44, 16 October 2007 (CDT)

Wait, do you want an infobox? --Robert W King 16:45, 16 October 2007 (CDT)
Ok, I'm caught up. You want an infobox. I can make this easily *but* I must know what criteria you want to be displayed. I had no input with the chemistry infobox I made and thus it is severely lacking in detail. --Robert W King 16:46, 16 October 2007 (CDT)


Hi David, thank you for correcting my English. I corrected yours too: "efficiently" ;-). Also I added that distillation is widely used in industry, somehow you lost that fact in cleaning up.--Paul Wormer 11:12, 18 October 2007 (CDT)


Can do easily. How do you want it formatted? --Robert W King 12:51, 18 October 2007 (CDT)


Hi David, are you sure the following is correct?

A volume of earth atmosphere consists of 21% of the oxygen molecule O2.

and has the meaning: 21% (in volume) of the atmosphere is oxygen?--Paul Wormer 09:35, 19 October 2007 (CDT)

small addition to NMR

see if you like this addition - else delete it. Robert Tito |  Talk 

Negative nuclear spin explained

Hi David, your explanation is perfect. I was thinking of negative gyromagnetic ratio, but I didn't know that it existed. I hope you come up with a good "oxygen in air" sentence. Yours,--Paul Wormer 01:50, 20 October 2007 (CDT)

In the meantime I saw the new "oxygen in air" sentence: is it mass or volume percentage? (Difference is small, of course, oxygen and nitrogen being almost ideal gases with almost equal molecular masses, but still).--Paul Wormer 02:34, 20 October 2007 (CDT)

Antiparallel magnetic moment

Hi David, as wrote you before I am very much used to parallel spin and magnetic moment (positive g-factor). Now I learned from you that it is not always the case. (I could have known it, the very first table in my old Carrington-McLachlan textbook shows it). My question is: is this phenomenon due to the fact that a neutron has a negative spin g-factor? Or should I ask a nuclear physicist?--Paul Wormer 11:04, 21 October 2007 (CDT)


Hi, David - I've been trying to find someone from the Physics Workgroup active at the moment. I'd just like to make you aware of the Universe article. A note has been left on the Talk page arguing that this is not a neutral article because it doesn't mention Creationism. Here's hoping it doesn't turn into a battlefield... John Stephenson 00:46, 26 October 2007 (CDT)


Great job on the protein article. i have not read in detail but a quick skimming indicates it is in great shape. You did that from scratch? Chris Day (talk) 16:26, 26 October 2007 (CDT)


I set no standards for the template; I am assuming some kind of de facto standard will come out of the process. I would say choose what color you feel is appropriate ;) --Robert W King 12:55, 6 December 2007 (CST)

See my reply on the Chemistry workgroup page. --Robert W King 13:25, 6 December 2007 (CST)
Re:Phosphorus, you put "Developing" as opposed to an actual number; that particular metadata field wants a numerical input (1-5) as opposed to text. --Robert W King 17:00, 6 December 2007 (CST)
Template is now Elem_Infobox. What would you like to see in a Chem Infobox? --Robert W King 17:18, 6 December 2007 (CST)

Deletions/Image deletions

David, at any time to request a deletion, you can simply add {{speedydelete|Insert some reason here}} to the article/image space. --Robert W King 17:34, 7 December 2007 (CST)

You deserve to be credited...

Well, I see you were working away on party day, which makes you one of the shy boys. I’ll have to come and drag you in next month! Aleta Curry 23:44, 9 December 2007 (CST)


Hi David, I'm not so much in a hurry to have articles approved. As User:Pieter Kuiper pointed out to me, approval hides the real authors. However, I'm more than happy to approve some of your articles.--Paul Wormer 10:53, 20 December 2007 (CST)


David you write that Phosphate is ready, do you mean Phosphorus? If so, I'll read it tomorrow (here it is 7 pm and I quit).--Paul Wormer 11:52, 20 December 2007 (CST)

  • David, I read Phosphorus, and as it stands it is OK. I would like to extend it a little, though. I consulted Larry Sanger and he doesn't seem to care much about approval. What do you think? If you write the addition I can approve without problems. But I'm willing to add a few paragraphs myself (see talk:phosphorus for what I have in mind), which then has the drawback that it interferes with the approval. (Or maybe nobody cares and I can approve it anyway, even if I were to write some [minor] additions?)--Paul Wormer 10:15, 21 December 2007 (CST)

Subpagination thanks

Thanks for your work subpaginating articles, David! --Larry Sanger 18:38, 23 December 2007 (CST)


Hi David, I was hoping you could take a look at alcohol and see if the chemical formulas are correct (I have no chemistry knowledge to speak of, so I hope I didn't make an error.). I started the article because I wanted to write about the behavioral effects of ethanol, and I figured there should be an alcohol page first. Thanks. Richard Pettitt 16:15, 24 December 2007 (CST)

Years as pages...

Yes, we are. As the articles flesh out, so will the year-based pages. --Michael J. Formica 19:36, 27 December 2007 (CST)


It's easy. Say you have an article called "Big Easy" and you want a redirect from "The Big Easy". Just go to the Search box at the top left of the screen. Type in "The Big Easy". You'll get a message saying that it doesn't exist and asking if you want to create it. Click to create a new article. You'll now have a blank edit page. Scroll down to the bottom of the screen to Special Characters. Click on the link that says #REDIRECX [[]]. That should put it up on the edit page. Then type "Big Easy" in between the bracket. Save. That will make the redirect.


Hi David, we both wrote something about allotrope/allotropy. Maybe it is better that we merge the two articles and put a redirect?--Paul Wormer 08:19, 29 December 2007 (CST)


See query at Steroid. - Robert Badgett 23:49, 31 December 2007 (CST)

vector product

I know that it is the same as cross product: the last sentence of the article was:

The term "vector product" is a synonym of cross product.

I thought of a disambig, but decided that an article adds to the article count and gives more info. In the meantime I added a more explicit reference.--Paul Wormer 01:48, 4 January 2008 (CST)

David, I extended vector product with the text of cross product (and took the opportunity of a little rewrite plus small extension). I changed cross product into a redirect, but don't know what to do about the discussion page of the latter. Further I don't feel comfortable with this {{subpages}} business, could you take care of it? And finally, shouldn't we do something about allotrope and allotropy as well?--Paul Wormer 04:11, 5 January 2008 (CST)

River names

David, thanks for your remark about river names. Please give me a note when you have more information regarding naming of river articles. --Igor Grešovnik 12:39, 4 January 2008 (CST)

Lavigueur family

Hi David. I'd like to know more about why the bibliography was removed. :-) -- Hugo Voisard 13:25, 4 January 2008 (CST)

It probably wasn't removed; just moved to an appropriate "subpage", the Bibliography subpage located at Lavigueur_family/Bibliography. --Robert W King 13:30, 4 January 2008 (CST)
Robert is correct, and I replied on Hugo's talk page regarding this. David E. Volk 13:34, 4 January 2008 (CST)
Thank you for the information. :-) -- Hugo Voisard 23:53, 4 January 2008 (CST)


Just to let you know, when you upload images and see {{subst:3~ }} in the area where it says CZ_username =, just leave it as is. It automatically signs your username (it was a dirty hack). So for me, {{subst:3~ }} produces Stephen Ewen as soon as I save a page. Crystal ksmiletris.png Stephen Ewen 18:12, 4 January 2008 (CST)

Ah, the above is obsolete because I just figured out how to use ASCII to cause ~~~ to automatically enter the edit window. Stephen Ewen 21:49, 4 January 2008 (CST)

viruses template

Did you ever get help with this? Stephen Ewen 02:55, 12 January 2008 (CST)

New NMR guy

Hi David, I'm also glad that we have a new (physical) chemist on board. The content of his NMR article is OK, but the format needs fixing up. How will we proceed, we simply go ahead and fix it (and explain in the talk page why), or will we ask him to adapt it himself? He signed the article and I'm afraid that if we take his signature away he will misunderstand that. --Paul Wormer 09:51, 12 January 2008 (CST)

Reply to welcome

Thank you for the welcome.

I have never used a wiki before and I am just learning how to use this system.

I am not sure if this is the page to reply, so please forgive if this is the wrong place.

I just added an article on NMR spectrosocpy; however, unlike your page and that of most others it does not have a STATUS tab (approved/ draft etc.) attached to it. Your comments are welcome.

Thanking you.

Sincerely yours. Talluri Sekhar


 David E. Volk   talk

Spelling variants

There is a problem with all of these pages you created involving the name "sulphur/sulfur". Can you put the variant spellings in the lead of each article, and also redirects to each article? Otherwise, searches will not give the pages for what is internationally an equally common spelling to the American one, and it is also not good for CZ to be American-focused. Many thanks. Martin Baldwin-Edwards 13:44, 16 January 2008 (CST)

NMR spectroscopy : an attempt to get it approved

--Sekhar Talluri 16:39, 16 January 2008 (CST)

I edited the metadata page for my article on NMR spectroscopy in an attempt to send it for approval by you and P. Wormer as editors. However, it appears that somehow I have approved it myself:-) Please feel free to undo/do/fix whatever is necessary , but do consider it for approval. Sincerely


David: Kindly do not remove the Psychology Catalogs category from the bottom of psych pages. It is there to provide a structural guideline.

Secondly, (re: Tao Te Ching) it is fprmatting convention to bold only the topic of an article, not variations on spelling, etc.

Thanks... --Michael J. Formica 18:36, 21 January 2008 (CST)

Drug pages

See lovastatin and simvastatin for what I did:

  • Made brand list into three columns
  • Automated link to FDA information

Look at second green box on for details.

Thanks for adding image into Hydrodesulfurization

David, thanks for adding your chemical reaction image into the hydrodenitrogenation section of the Hydrodesulfurization article. It really dresses up that section. Regards, Milton Beychok 12:22, 4 February 2008 (CST)


Hi David, I was wondering if you could add an image to the methylphenidate article. Thanks! --Richard Pettitt 17:57, 4 February 2008 (CST)

Thanks very much! --Richard Pettitt 10:02, 6 February 2008 (CST)
