Welcome

Tasks: start a new article • add basic, wanted or requested articles • add definitions • add metadata • edit new pages

Welcome to the Citizendium! We hope you will contribute boldly and well. Here are pointers for a quick start, and see Getting Started for other helpful "startup" links, our help system and CZ:Home for the top menu of community pages. You can test out editing in the sandbox if you'd like. If you need help to get going, the forum is one option. That's also where we discuss policy and proposals. You can ask any user or the editors for help, too. Just put a note on their "talk" page. Again, welcome and have fun!

You can find some more information about our collaboration groups if you follow this link CZ:Workgroups.You can always ask me on my talk page or others about how to proceed or any other question you might have.

Welcome, new editor! We're very glad you've joined us. Here are pointers for a quick start. Also, when you get a chance, please read The Editor Role. You can look at Getting Started and our help system for other introductory pages. It is also important, for project-wide matters, to join the Citizendium-L (broadcast) mailing list. Announcements are also available via Twitter. You can test out editing in the sandbox if you'd like. If you need help to get going, the forum is one option. That's also where we discuss policy and proposals. You can ask any administrator for help, too. Just put a note on their "talk" page. Again, welcome and thank you! We appreciate your willingness to share your expertise, and we hope to see your edits on Recent changes soon. --Larry Sanger 20:58, 3 April 2007 (CDT)

loved your "thought experiment" on the forums. Nancy Sculerati 06:03, 22 April 2007 (CDT)

Image(s)

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

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)

ToApprove

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)

Oxygen

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)

Isotopes

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

English

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)
