Quantum mechanics
Now set up with an experimental advanced subpage. i migrated information from the previous article to various subpages too. Chris Day 14:00, 1 April 2008 (CDT)

Would you please critique my article on the compressibility factor of gases?
Paul, I have been working (in one of my sandboxes) for over a week on an article to be called Compressibility factor (gases). I am about ready to create it as a CZ article. It can be viewed at User:Milton Beychok/Sandbox2. Would you be so kind as to read and critique it? You may leave your critique comments on the talk page at User talk:Milton Beychok/Sandbox2. Thanks in advance, - Milton Beychok 14:32, 1 April 2008 (CDT)

Compressibility factor (gases)
Paul, if you would still like to nominate Compressibility factor (gases) for approval, please do so. Regards, - Milton Beychok 12:42, 14 April 2008 (CDT)

AD/CE
Probably worth setting up a thread on the forums to discuss this, followed by a formal policy. There was a big go-round on Wikipedia about this point (although I think it was BC versus BCE, there). J. Noel Chiappa 17:33, 14 April 2008 (CDT)


 * There's been a thread on the forum about this for some time (What about Anno Domini and BC), think the decision is author/workgroup preference, in that there are some areas where CE/BCE is the only acceptable form. It does seem that CE and BCE are rapidly increasing in use. I searched on Google for  "5th century CE" (32,000 hits) vs "5th century AD" (172,000 hits) and suspect that the relatively high hit rate for CE use does reflect a significant unease with using AD and BC. See http://www.religioustolerance.org/ce.htm for rationale and background. So personally I'd favour CE and BCE, anticipating that these will become dominant usage. I think the only real objection to them is that they are less well known, but this seems to be changing.Gareth Leng 02:43, 15 April 2008 (CDT)


 * Hmmm. Well, it would be nice if it was formalized as a policy. Also, I'm not big at all on leaving it up to the authors, that will result in a real mish-mosh, and it will also result in either i) people racing to be the ones to start articles, or ii) people getting into revert wars where they convert back and forth. (One necessarily gets one or the other, if we have 'author decides', no?) Although I suppose anything that caused a 'land rush' on starting articles isn't all bad! :-) J. Noel Chiappa 10:27, 15 April 2008 (CDT)
 * I would just use both; I typically use: 2008 AD(CE) or some variant of. That way you satisfy everybody. --Robert W King 10:30, 15 April 2008 (CDT)

As long as it was your idea...
...yes ;-) --D. Matt Innis 19:09, 15 April 2008 (CDT)

Compressibility factor (gases)
Approved! Looks like the engineering and chemistry workgroups are off on a great run! --D. Matt Innis 19:19, 21 April 2008 (CDT)

Please read my comment of April 11th on the Talk page of Mole (unit)
Paul, I proposed a re-write of the Examples section of the Mole unit article which is mostly a simplified rewording of most of that section. The only part that I removed was the part that I thought would be more appropriately included in an article on chemical stoichiometry.

I hope that my proposed re-write doesn't endanger our working relationship. Please let me know what you think of it. Milton Beychok 01:08, 23 April 2008 (CDT)

Faraday
Thanks for the nudge; I had gotten confused about whether I was or was not allowed to copyedit while the article was in 'Nominated', so I solved my confusion by doing nothing! I have posted on the Talk:, and once I'm sure I won't be causing a problem, I will give it a go-through. Mind, I will only be able to re-arrange what's there to be clear; I have a basic understanding of E+M, and so can explain basic physics things better, but I know little of Faraday's life or work, and so will be relying on the existing article contents for all the data. J. Noel Chiappa 14:06, 23 April 2008 (CDT)

PS: You might want to archive some of the older stuff off the top of your personal Talk: page; it's getting a bit big. The template on both this and the "/Archive 1" subpage gives a nice look, if that's useful to you. J. Noel Chiappa 14:06, 23 April 2008 (CDT)

van der Waals
Hi Paul, please take another look at the references there, as explained on the talk page. Thanks! Btw, just saw that you already started spherical harmonics - I will probably join in there soon. -- Daniel Mietchen 17:45, 23 April 2008 (CDT)

Physical Properties Templates
Hi Paul,

I posted this on Talk:Cadmium, but wanted to get some feedback from Chem Editors so figured I'd just ask...

I had this kooky idea of trying to store materials physical properties data in templates so we can call it up from multiple locations and keep it current. That way we can do things like this:

Selected Electronegativities:

Hydrogen

and... Selected Melting Points:

Hydrogen

and also....

Resizable Periodic Table of Elements ...pretty easily.

Also, I've started the Physical properties template to display the info in the articles (please see Lead or Cadmium/MSDS for examples). I have (I believe) left open the option of using the system for any material, not just the chemical elements. Any objections? Reasons it won't work? Things I should change? Feedback is welcome....--David Yamakuchi 10:23, 25 April 2008 (CDT)

I agree that the editing of the property values need to be easy enough that a Non-Technical Person (NTP) can do it without confusion or errors. Thus far, I have been focused on getting the system working and then spent a little time on the "view" of the data, which right now, looks like it might live in the MSDS or Isotopes page. In the future, perhaps we can write different "viewers" for the data, including maybe a "edit the data values viewer".

At this time, if you click on the "xxxxx/Physical Properties" link at the bottom of the table/view, it takes you to the template to add data (stored in the template in the form of a switch statement), which is maybe a simpler syntax (better for NTPs) for the data than the wikitable was with all it's added "centers" and pipes and such. I'm currently looking at a slightly more sophisticated system for the Isotopes (or Isotpes as I guess we are now spelling it).--David Yamakuchi 11:16, 1 May 2008 (CDT)

Mole (unit), yet again
Paul:

I understand your revision of the lead-in section and have no problem with it.

However, I would still like to re-write the Examples section as per my comment of April 11th on the Talk page of the aricle (the next-to-last comment on that Talk page) if you agree to it. I think that my rewrite will be more understandable by non-physicists.

I assume you are at home again and I hope you enjoyed your stay in California. Regards, Milton Beychok 11:26, 28 April 2008 (CDT)

Of course we are not at war
Paul, that was just my way of saying that it wasn't really that important to me and I would rather drop the subject. Best regards, - Milton Beychok 11:42, 29 April 2008 (CDT)

Your attention needed..

Please look at Fluid catalytic cracking
Paul, if you have some spare time, look at Fluid catalytic cracking and tell me what you think of it. It is the most difficult article that I have undertaken at Citizendium because it has been over 50 years since I designed an FCC unit and (a) my memory is not what it used to be and (b) the advances made in those 50 years have been numerous. Regards, Milt - Milton Beychok 03:44, 9 May 2008 (CDT)

Since you once served an internship in an ammonia plant
Paul, you might enjoy a stroll down memory lane by reading Ammonia production. - Milton Beychok 00:48, 11 May 2008 (CDT)


 * Paul, when you have the time, I would appreciate it if you looked at Ammonia production and gave me your comments. Thanks, - Milton Beychok 12:49, 7 August 2008 (CDT)


 * Paul, thanks very much for your comments about Ammonia production. As you suggested, I have now added a paragraph discussing the two ways in which nitrogen is obtained for use in the last Haber-Bosch step.


 * As for your comments on the Haber process article, I have just finished some rather extensive edits to that article (see the Talk page of the article) to try and clean it up and decrease the focus on electrolysis of water. In fact, I have stated that if there are no objections forthcoming in the next week, I plan to drastically shorten the discussion of electrolysis and I have more or less suggested that a stand-alone article is needed for electrolysis.


 * As for merging the Haber process into the Ammonia production article by a redirect, I would rather not do that. The Haber process is merely a discussion of the last step in the synthesis of ammonia discussed in Ammonia production and I see no harm in an article devoted only to that process. Besides that, redirecting the Haber process means deleting its contents and that might ruffle some feathers if it were done with having a consensus to do it. I would rather keep on writing new articles to build up an "infrastructure" of chemical engineering articles and not get involved in what might get to be lengthy process of achieving concensus to merge. Milton Beychok 01:02, 9 August 2008 (CDT)

Formatting of article list on your user page
Hi Paul, just reformatted the list to allow for easy progress monitoring. Hope you like it; if not, feel free to revert. -- Daniel Mietchen 05:12, 13 May 2008 (CDT)

I just noticed this
I just noticed this one of Larry Sanger's archived Talk pages:

Milton added this to WP. Now WP has two articles on the same subject, a good one (by Milton) and a poorly done one, this. Up to the 3 000 000! --Paul Wormer 04:28, 12 May 2008 (CDT)

I take it that you don't like my having posted my "Fluid catalytic cracking" on Wikipedia. Is that correct? Milton Beychok 16:49, 14 May 2008 (CDT)

Definitions
Hi Paul, I too had been using lower case to start the definitions, i think we agree on that style. However, Larry corrected some of mine and it says to use upper case to start the definition at CZ:Definitions ("Begin the definition with a capital letter, and end with a period. "). It kind of make sense since there is a colon between the article name and the definition. I suppose that it also means the definition can be used on its own as a sentence without the prefix of "Article name:" although, I do not thing that is currently the case. Chris Day 10:28, 16 May 2008 (CDT)

Excellent Cauchy
Juste-milieu on Cauchy--I was a math major at Notre Dame back when it was just as Catholic as Cauchy was, and so he was our great hero! The article integrates the man, the math and the milieu very well, so I signed the approvals. Richard Jensen 07:15, 18 May 2008 (CDT)

Energy
Hi Paul, we are currently trying to design a system that handles disambiguations (see here and here for details). This also effects the way terms with multiple uses are to be used in Related article subpages and similar places. The ultimate goal is to have a consistent disambiguation handling system across CZ (another difference to WP), to list all the different uses at Energy (disambiguation) and to link from there to Energy (kinetic), Energy (chemical), Energy (mechanical), Dirichlet energy, Energy (psychology) and so on as articles get created on those topics. Groetjes, Daniel Mietchen 05:37, 22 May 2008 (CDT)


 * Ambiguous articles like this one are going to be moved to disambiguated versions thereof, and the 'blöd' message you see is just a reminder to fix that. I did that right now such that your user page looks normal again. Further splits of the article into subtopics of the sort listed above may become necessary with time. -- Daniel Mietchen 07:26, 22 May 2008 (CDT)

You probably saw a temporary state after I had created Faraday's law/Definition, but before I had gotten to Faraday's law (disambiguation). J. Noel Chiappa 10:27, 22 May 2008 (CDT)
 * OK --Paul Wormer 10:35, 22 May 2008 (CDT)
 * The definition seems OK, just the talk page was not properly set up, and I fixed that. I also saw the discussion on the name there and added my comment. -- Daniel Mietchen 05:20, 28 May 2008 (CDT)

Pipe
Yes the pipe works, we have been redesigning the R and Rpl templates to be as user friendly as possible. Also note that the green A pops up when it is up for approval, as is one on your list right now. Also note that you can indent now too, something that was not possible before. Here are a few example:

Energy Conversion Analysis
Sir: You are missing a point. This is Unites States of America and there are are some laws that need to be obeyed. I do feel that I have been abused as an author and that my initial input has been viloated. Thanks, Gordan

Need help with editing the Density article
Paul, I got interested in the Density article which got transferred from Wikipedia to CZ in 2006 without any revision to make it suitable for CZ. It contained a number of terminology errors and was very disorganized. I spent quite some time in the past 24 hours to correct the obvious errors and to reformat/reorganize it. As a result, I then upgraded it from status 4 to status 2.

However, it contains an equation for calculating the density of crystalline mmaterials given certain crystallographic data and the molecular mass ... which I think needs quite a bit of discussion and explanation. In all candor, I don't understand the equation.

I noticed that in the Kilogram article, you contributed a discussion of the silicon project and it seems to me that your discussion is about that subject of calculating density from crystallography data and molecular mass. When and if you have the time, would you look at the Density article and see if you could contribute an understandable discussion of the equation given there in the "Measurement of density" section?? Thanks, - Milton Beychok 18:26, 10 June 2008 (CDT)


 * Milton, I had a quick look, but it seems to me that the crystal density formula is only correct for orthogonal a, b, and c axes (cubic lattices). For skew axes the volume of the unit cell must be extended to a formula containing the angles between the basis vectors. (Volume of a general parallelepiped). --Paul Wormer 03:27, 11 June 2008 (CDT)


 * Paul, could you perhaps extend the formula for skewed axes and also add some explanatory text? Or do you think that perhaps that method of obtaining a theorertical density is too esoteric for inclusion in the density article? Would it be better to move the formula into the article about crystals or a new one about crystallography? I would appreciate your doing whatever you can and explaining it on the Talk page of the density article. I just don't feel qualified to do any of that. Thanks, - Milton Beychok 12:01, 11 June 2008 (CDT)


 * The equation is simple if you know vector algebra, it is

V = \mathbf{a}\cdot (\mathbf{b} \times \mathbf{c}) $$
 * where a, b, and c span the unit cell and we have an inner and a cross product, respectively. Do you think presenting this would be useful (given the amount of opposition against mathematical formulas)? --Paul Wormer 09:56, 13 June 2008 (CDT)


 * I haven't noticed any great opposition to formulas other than in some discussion on the forums. When CZ finally attracts many more active physicists and engineers (other than the very few that are now active), that opposition will disappear. As for your formula, I don't know vector algebra and don't understand your equation but I accept it because I trust you. Would you please revise that section of the Density article and include some explanation so that even I would understand it? Or, if you feel that section should just be deleted, than remove it entirely .. with an explanation on the Talk page. - Milton Beychok 10:47, 13 June 2008 (CDT)

Milton, where did you get that formula for the crystal density? To me it seems to hold only for molecular crystals consisting of one type of molecule, like crystalline naphtalene (there is one molecular mass in it). In atomic crystals, like NaCl (table salt), one usually has different types of atoms with different masses in the unit cell.

The formula for volume is easy. Remember, the volume of a parallelepiped is the area of its base surface times its height. Now, b&times;c is a vector of length equal to twice the area of the triangle that has b and c as sides. The direction of this vector is orthogonal to the plane of this triangle. Hence a&sdot;(b&times;c) is the height of the parallelepiped times the area of the base surface.--Paul Wormer 11:21, 13 June 2008 (CDT)


 * Paul, I don't know where that formula for crystal density came from. It was already in the article when I stumbled upon the article a few days ago and began to edit and improve it. Presumably, it was either added earlier by someone in CZ or it was already in the Wikipedia article when someone transferred it to CZ about 2 years ago. I checked the current Wikipedia article and it is not in the current WP version. I have also searched the Internet and found that there is such a method ... but could not find that same equation anywhere. - Milton Beychok 12:25, 13 June 2008 (CDT)


 * Milton, I found in a very old physical chemistry book (A. Findlay, 2nd ed. 1941) an example of a density calculation of what Findlay calls "rock salt" (above I called the same compound "table salt"). First Findlay shows that there are four NaCl molecules per unit cell (which in this case is a cube with one lattice parameter: a = 0.56 nm). He does this by counting, for instance, the atoms on the 8 corners are shared by 8 unit cells and have therefore weight 1/8. The face-centered atoms are shared by two cells and have weight 1/2, and so on). The molecular mass M of NaCl is 58.454, N = 4, a = b = c = 0.56 nm and this is all you need to compute the density of rock salt [in g/(nm)3]. To explain that N = 4 one really needs a picture of the unit cell, which is easily drawn since it is a cube. What do you think, should we go all the way and add this example?

--Paul Wormer 02:58, 14 June 2008 (CDT)


 * Paul, you have made my day! When I use that formula in the Density article with Findlay's example data, I get 217.9×10-23 g/(nm)3 which is equivalent to 2.179 g/(cm)3. My copy of Handbook of Chemistry and Physics has the density of sodium chloride as 2.165 g/(cm)3. The difference is less than one percent.


 * Yes, I will add Findlay's example. Is this his book: ?


 * If you would be so kind as to email me a simple sketch of the cube and explaining how to count N, I will produce a drawing and upload it into the article as well. By letting me add the example and the sketch, you will be free to nominate the article for approval some day if you want to do so. You can email me at mbeychok@cox.net or you can fax me a copy of the page from Findlay's book at: 949-706-9634 (preceded by the country code for the USA). Thanks again, - Milton Beychok 12:01, 14 June 2008 (CDT)
 * I scanned the relevant pages and sent them as pdf to mbeychok@cox.net--Paul Wormer 05:02, 15 June 2008 (CDT)
 * PS I extended the article on the vector product with the formula for the volume of a general unit cell that I mentioned earlier, see: Vector_product--Paul Wormer 07:55, 15 June 2008 (CDT)

cross product
I had forgotten about that lame image. We should try to do better, but I just now back from vacation so I likely won't touch it for a few days. I'll try to come up with a better one. Making it ourself keeps the copyright's consistent, so I would rather do that. David E. Volk 08:19, 17 June 2008 (CDT)

Thanks for corrections to Density
Paul, thanks for your corrections to the section on xray diffraction crystallography. I don't know how in the world I messed up the reference to Findlay's book. I guess I better start going to bed earlier.

The HTML for a center dot renders like this &sdot; in my Internet Explorer browser, so I changed it to × instead.

Thanks again, Milton Beychok 11:33, 18 June 2008 (CDT)

Party!
Hi Paul! So, you've been working but not partying? Come add your name to the cast of characters at July party! Aleta Curry 20:28, 2 July 2008 (CDT)

Scary guide
Don't worry about it too much, the elem_infobox, that is. It is not that YOU personally need to do it, but that someone should before we approve the article. The easiest way to fill in the chem_infox or elem_infobox is to simply copy one from another article (via edit button to see the code), like ketoconazole or Hydrogen, and then change the relevent parameters. David has been busy changing the element box, so I need to go brush up on that one also, but I think he is going to do that for every element so we don't need to worry so much about that. Cheers. David E. Volk 10:40, 7 July 2008 (CDT)

Stokes Theorem
Hi Paul

Thank you! I'm not really done with the divergence theorem yet, I was thinking of inserting some pictures to explain the proof I'm gonna give.

But when I'm done, I'll do Stokes aswell. And after that, maybe Green's Identities :)

Emil Gustafsson 05:47, 10 July 2008 (CDT)

Your request that I look at Energy (science)
Paul: First, let me say that I think your lead-in paragraph is very good. I have taken the liberty to slightly reword/rewrite it so as to:


 * Use a little more colloquial English. For example, I used "forms" instead of "manifestations".
 * Add internal links to existing and non-existing articles.
 * Make a very few revisions for better clarity. For example, pumps do not run on gasoline ... instead, they may be driven by gasoline-fueled engines.

In my personal opinion, as you probably already know, keeping things as simple as possible is the best course ... and I think you did a good job of that. I think that saying energy is a "measurable" quantity is simpler and more commonly understood than is the word "scalar".

My reworded or rewritten version is available at User:Milton Beychok/Sandbox2. You can read it there and decide whether or not you wish to use it or use parts of it.

I will look at the rest of the article in the next few days, but I suspect that I won't be too much help there. However, I will try to be helpful. Regards, Milton Beychok 17:28, 23 July 2008 (CDT)


 * Paul, I just added another section in my Sandbox2 about your table of "combustion enthalpies" for your consideration. I hope it is useful. Milton Beychok 13:00, 24 July 2008 (CDT)

Pictures
Steve definitely knows the details better than I do. However, one rule I know is that all pictures published (note: not created but published) before 1923 are in the public domain; this is confirmed by the table in CZ:Images, to the right. So any image with publication info from before that date should be okay. This means that images #3, #4, #5 and #8 on http://commons.wikimedia.org/wiki/Category:James_Clerk_Maxwell should be okay. Let me know if you need to know more details. -- Jitse Niesen 17:44, 4 August 2008 (CDT)

Finger crossing
Thanks Paul, your finger crossing sent the tropical storm more northly and thus it hit east of Galveston around Port Author. Of course, the folks over there might not like you so much now! David E. Volk 15:57, 5 August 2008 (CDT)

Haber process
Paul, a week ago I posted a message on the talk page of the Haber process article explaining my intention to shorten the electrolysis section down to no more than about two paragraphs. Since no one objected during the week, I went ahead today and shortened that section as I said I would. I also corrected numerous errors in the chemical reactions in the other sections. Milton Beychok 22:39, 15 August 2008 (CDT)

Ether
Thanks for the warning Paul. As soon as I saw "ether" was the subject of the change, and you being a physicist, I instantly knew what you were up to. Luckily Gustav missed us completely in Galveston, but we all prepared our houses and chemistry labs on Friday just in case. David E. Volk 08:42, 2 September 2008 (CDT)

Have you seen my photo?

Paul, unless you want to keep it completely private, would you tell me how to find your sandbox or scratchbox? Milton Beychok 23:12, 21 September 2008 (CDT)

Rubbish
Paul, I am very interested to know why this article did not fit your criteria (both scientifically and regarding the relevance to our topic). Although it is in complete contradiction with the definition of the topic to treat structure of water separately (see my response to Matt, minutes before yours), my scientific curiosity urges me to discuss these matters on a separate page, say structure of water. Would you join? Pierre-Alain Gouanvic 03:08, 27 September 2008 (CDT)

Roy paper
Moderately positive? Sorry I've given that impression, no it's utter garbage. I tried to hunt down the journal as Springer stopped publishing it in 2003, seems to have been picked up by a house I hadn't heard of, and Roy is the editor. I certain;y haven't inserted any comment even vaguely supportive anywhere (unless by accident), my edits to tone down commentary on it may have been too gentle.

WP content in "Hydrogen bond" article?
Hi Paul,

I noticed that you have worked extensively on the Hydrogen bond article. I expect soon to move that to the featured article (draft) on the Welcome page of CZ, but I have a question about the possible WP content of the artilce. If it contains such WP content, then it should indicate so on the article. In any case, I believe it should be so indicated, but could you confirm this for me, and if it should be so indicated, could you do that?

James F. Perry 18:32, 13 October 2008 (UTC)

Thanks for the HTML idea!
Much easier. I still have some computer science things where I need to have things like summations in fractions, and I am rapidly thinking of drawing them with the Microsoft Equation Editor and saving them as .png.
