Featured picture candidate

An animation uploaded by you has been promoted to featured picture status Your image, Image:Translational motion.gif, was nominated on Misplaced Pages:Featured picture candidates, gained a consensus of support, and has been promoted. If you would like to nominate an image, please do so at Misplaced Pages:Featured picture candidates. Thank you for your contribution! 28 January 2007 (UTC)

Hi Greg,

Just to let you know that the Featured Picture Image:Translational_motion.gif is due to make an appearance as Picture of the Day on May 14, 2007. If you get a chance, you can check and improve the caption at Template:POTD/2007-05-14. howcheng {chat} 18:42, 19 April 2007 (UTC)

Featured Picture Candidate

I nominated one of your animations (Image:Translational motion.gif) to be featured. See Misplaced Pages:Featured picture candidates/Translational Motion. —EdGl 02:05, 18 January 2007 (UTC)

Thanks. I wrote back on your personal discussion page. Greg L 20:45, 18 January 2007 (UTC)

(concerning your last post on my talk page) You should definitely speak out and state your case on the featured picture candidates page! —EdGl 21:27, 18 January 2007 (UTC)

I left a note on Antilived's talk page concerning his vote, directing him to my talk page. —EdGl 01:36, 19 January 2007 (UTC)

There are two users who voted neutral but clearly like it and lean support, voting neutral only because of minor issues. In this case it's not really a bad thing, since there are a few support votes and no oppose votes. Only a few more days left. —EdGl 04:47, 22 January 2007 (UTC)

That's the way I see it. Thanks. Greg L 05:13, 22 January 2007 (UTC)

Woohoo, the animation is now featured! →EdGl 00:26, 29 January 2007 (UTC)

It says on the picture-of-the-day page that "featured images are currently selected in the order they were promoted". So, it won't be on the main page in a while. They have already selected pics up to March 1st. →EdGl 01:00, 30 January 2007 (UTC)

• Of course, that's fine. I only picked Temperature because it was the first. Regards. Trebor 07:26, 31 January 2007 (UTC)

Elastic Collisions

I've been meaning to ask you - in the animation, are the atoms experiencing elastic collisions or inelastic collisions? In the animation it looks elastic, but apparently they should be inelastic. Now, I know making the collisions inelastic would be a lot harder, it's just that as an AP Physics student I pick up on these things ;) →EdGl 16:18, 27 January 2007 (UTC)

Very cool indeed! I think the inelastic collision article contradicts what you're saying, which is why I got confused there for a second. Maybe you can use your expertise to help along that article and any other relevant articles you may find. We can't have misinformation in an encyclopedia! →EdGl 16:59, 27 January 2007 (UTC)

I'm talking about this sentence: "Collisions between molecules of a gas or liquid may also be inelastic as they cause changes in vibrational and rotational energy levels." Hmm, I guess this is something you wouldn't be able to see in your animation, since the Helium is represented by circles rather than "atomic shapes". I'm guessing the helium atoms you are representing in the animation are diatomic molecules rather than single atoms, am I right? It could be that you are envisioning atom-to-atom collisions while I am thinking about molecule-to-molecule ones. I'm assuming there's a difference (?). →EdGl 17:30, 27 January 2007 (UTC)

This diff shows it was User:Numsgil who added this information. I left a not on his talk page saying I'll remove the info from the article. I'm not going to add anything to the article, but if you see something that could be added, you should; it's a rather poor-quality article (except for the animation lol). Hey, maybe you could put your soon-to-be-featured animation into the elastic collision article? I think that's a great idea! →EdGl 18:26, 27 January 2007 (UTC) 

Kilogram

I edited your recent addition to the kilogram page and added a citation needed tag. I noticed that you labeled the source you got the information out of in the edit summary, but not in the article. Since I don't have that source, it would be great if you'd check and make sure I didn't introduce any errors in my edit, make sure that the information near the fact tag I added is all in the reference you were using, and add your new reference as a footnote. Thanks!Enuja 08:38, 8 March 2007 (UTC)

• Thanks so much! I'm a bit fan of the info you added; it's great to know what the prototype is made of and when it was made. I'm happy with the statement of ratification by the 1st CGPM; it doesn't read as repetitive any more. Enuja

Images

Sorry I didn't reply sooner - thanks for the offer, but I'm quite content with the images already on my page. They have amazing quality, by the way. :-) Mrug 21:10, 28 March 2007 (UTC)

Image:Z-machine480.jpg listed for deletion

An image or media file that you uploaded or altered, Image:Z-machine480.jpg, has been listed at Misplaced Pages:Images and media for deletion. Please look there to see why this is (you may have to search for the title of the image to find its entry), if you are interested in it not being deleted. Thank you. — Rebelguys2 17:58, 14 April 2007 (UTC)

So, what was the result? They seem to have decided to delete it, please correct me if I'm wrong. Mrug 10:47, 20 April 2007 (UTC)

So How About That?

Your animation will be on the main page! I'm excited, and I'm sure you are too. Congratulations. →EdGl 23:22, 19 April 2007 (UTC)

It has taken me a few days, but I've left a reply to your comments at Talk:Sucralose. Enjoy! --Ed (Edgar181) 20:37, 25 April 2007 (UTC)

HCP Close packing

Hello, I am an NYU student and an intern at the Mayo Clinic. For my computer program I need to create a lattice for a "closest packing" of same-size spheres. I was wondering if I could ask your help.

I have so far determined how to make each plane of my A-B-A-B-... HCP lattice but I dont know the z coordinates.

In otherwords I have the first plane, the balls that are resting on the z=0 plane, those balls all have their centers with a z coordinate of r, the radius. Then the balls are distributed correctly according to the HCP packing on the z=r plane. Then I have the next level on top of the first, those are all distributed according to A-B-A-B stacking but I don't know what the z coordinate is. It's clearly not z=2*r or z=3*r. So far my guess is z=r+SQRT(3)*r , but I have no geometric way to prove it.

Sorry if this was confusing. Thanks for any help. And thank you ginormously for your photos on the article. Mangledorf 21:39, 25 July 2007 (UTC) 

So, I have a new guess. If the next ball on top of three balls forms a tetrahedron then the difference should be the height of the terahedron ( SQRT(6) *(a/3) ) where a is the length of the side and the length is 2*r so the height of the sec ond row would be r+SQRT(6) *(2*r/3). Is this correct?

See my response here on your talk page. Greg L (my talk) 23:01, 25 July 2007 (UTC)

Thanks for the links, the one had exactly what I needed. Turns out it is a tetrahedron even if I had to get out the tennis balls to prove it to myself.Mangledorf 20:49, 26 July 2007 (UTC)

The formula is the height of the tetrahedron formed by the centers of four spheres. Imagine three balls on the ground in a triangle (this arrangement tessalates into the entire plane) then place on ball in the middle. This forms a normal tetrahedron who's height is SQRT(6) *(2*r/3), and that'll be the difference in the z-direction for each stack. It's much easier to prove it with actuall object than on paper, but it matched the first paper you mentioned. Mangledorf 16:43, 27 July 2007 (UTC)

Mangledorf: I can confirm that your formula must be the correct one. I apparently forgot just how far I must have zoomed in with my CAD program when setting the z-axis but I managed to nail it amazingly close. The size of the balls in the Fig. 2 ray-tracing is Ø 10.16 mm (r = 5.08). Shown below is the results of your formula (top) and my CAD program (bottom):

8.295 605 262 225 696 492 561 47 mm
8.295 605 253

Are you going to add this formula to the Close packing article? Greg L (my talk) 17:12, 27 July 2007 (UTC)

I would like to add it. When I have it totally straightened out and a good reference source made out, I will. Thanks for the back up. I was actually surprised it wasn't on the site to begin with, but that's what we're all here to do, eh? Mangledorf 20:32, 27 July 2007 (UTC)

Thermodynamic Definitions at T=0 in a vacuum

Thanks for the interesting question on my talk page. I haven't contributed to Misplaced Pages lately and my opinion is definitely not authoritative, but I try. I think most people in thermo define internal energy or enthalpy based on what they reasonably think will cause a significant change in the system they are studying.

Imagine a box with a shaft sticking out of it in a vacuum at around T=0 with the shaft poking out of the vacuum chamber somehow. Something in the box makes the shaft turn for a while, and that motion does useful work or generates heat outside of the vacuum chamber.

Maybe there's some Casimir effect gizmo in the box utilizing electromagnetic force due to changes in zero point energy. Or maybe there's a weight falling within the box utilizing gravity due to changes in height. Or maybe there's some radioactive material in the box. But the energy inside the box is decreasing while work is being done or heat is being generated outside.

That energy inside the box is thermodynamic internal energy at T=0 in a vacuum. See the table of intensive and extensive variables in section 1.3 in Alberty's http://www.iupac.org/publications/pac/2001/pdf/7308x1349.pdf and the equations in section 1.4. So the answer to your question is no. U does not have to exclude zero point energy. U should include ZPE if its inclusion will significantly alter the system under consideration. But there's no need to include it as an additional "tally" that just remains constant during a process. Flying Jazz 05:52, 11 August 2007 (UTC)

I would not write At T=0, these crystals have minimal internal energy (retaining only that due to ZPE). I would either remove the word "only" or, better yet, remove the phrase in parentheses entirely. Alberty's paper (a publication of IUPAC so it should carry some weight for Misplaced Pages) makes it clear that internal energy may include or exclude many different terms. Flying Jazz 14:13, 11 August 2007 (UTC)

I cited the Alberty reference to answer a question you left on my talk page. All I meant to say is that thermodynamic potentials like internal energy and enthalpy are useful because the variables in the particular system under study determine whether the potentials include or exclude some terms. But Alberty only uses the word "temperature" a few times in that article, so I don't think a reference to Alberty is justified in the Thermodynamic temperature article. I hope you consider reducing the length of many of your Notes in this article. I've never seen such tangential Notes in Misplaced Pages. If the information is useful but tangential, it should be added to other articles and linked to instead of placed in a Note. I'd also consider removing the History section. We already have History_of_thermodynamics and Timeline_of_thermodynamics,_statistical_mechanics,_and_random_processes for historical information. Details about contributions should be included in the biographical articles. Sorry if I sound overly pushy, but the article as a whole is too long and cumbersome in my opinion.

Featured image nominated for delisting

I saw the image above and was surprised to see it was a featured image of Misplaced Pages in spite of the fact that pressure and temperature values are given for a two dimensional representation. I've nominated the image for delisting. See Misplaced Pages:Featured_picture_candidates/delist/Translational_Motion to comment. Flying Jazz 00:17, 12 August 2007 (UTC)

What’s your problem? I wish I had never contacted you asking your opinion on a mathematics issue. People like you make editing Misplaced Pages so un-fun. That’s fine, I’ll play your petty game. Do you just go around in the world angry over something and take your frustrations out on others? Greg L (my talk) 03:41, 12 August 2007 (UTC)

P.S. Regarding deleting the above comment from your user page as a “personal attack”, unfortunately, it’s not; they’re all fair questions given the way you seem to operate. I note that a period table template you made was nominated for deletion (see entry here) back in January. It apparently got deleted as it no longer exists. That makes me wonder if you’re still smarting from that experience and want to “spread the joy.” Gee, thanks. I suggest we part ways and you go find someone else to pester. Greg L (my talk) 04:32, 12 August 2007 (UTC)

Huh? I think asking "Should a factually incorrect image be a featured image?" is a legitimate question. If I have a volume of helium at the temperature and pressure indicated in the caption, will the atoms really be that close to each other? Will they really collide with each other that often? Those are my questions. You think asking "Do you just go around in the world angry over something and take your frustrations out on others?" is a legitimate question. That is your question. As for the periodic table issue, see Misplaced Pages:Templates_for_deletion/Log/2006_January_26#Template:Periodic_table. An editor came up with an fantastic template, and I was the first one to agree with the deletion nomination that you think I'm angry about. The deleted template wasn't even mine. Please don't take what I am doing personally. I don't mean to pester you. I am only trying to make a good faith effort to make the encyclopedia better, and I'm not angry about anything. I hope I can convince you not to be angry about anything either. Flying Jazz 05:21, 12 August 2007 (UTC)

Wikiquette

I have initiated a Wikiiquette alert about your recent behavior on Kilogram. As I understand the process, discussion from the alert is expected to occur on Talk:Kilogram.

I personally apologize for mentioning personal attacks on the talk page. I went and read No Personal Attacks after I posted my concern on the talk page, and it strongly suggests talking to users about personal attacks on their talk pages, not on the project talk page where the dispute is occurring. Enuja (talk) 00:00, 2 September 2007 (UTC)

Hogwash. Boy is that the pot calling the kettle black. I posted this response on your talk page:

Enuja, regarding your recent post on my talk page, I actually had come back to the computer after cooling off to tone down my flaming of JimWae when I saw that you had left your message about “personal attacks.” Anyone who wants to can click on this history link to see what I originally posted. While, I'm not exactly proud of it, it was all heart-felt and precisely what I meant at the time. I also read the Misplaced Pages:No personal attacks article. It says:

There is no bright-line rule about what constitutes a personal attack as opposed to constructive discussion, but some types of comments are never acceptable:

• Racial, sexual, homophobic, ageist, religious, political, ethnic, or other epithets (such as against disabled people) directed against another contributor. Disagreement over what constitutes a religion, race, sexual preference, or ethnicity is not a legitimate excuse.
• Using someone's affiliations as a means of dismissing or discrediting their views -- regardless of whether said affiliations are mainstream or extreme.
• Threats of legal action.
• Threats of violence, particularly death threats.
• Threats of vandalism to userpages or talk pages.
• Threats or actions which expose other Misplaced Pages editors to political, religious or other persecution by government, their employer or any others. Violations of this sort may result in a block for an extended period of time, which may be applied immediately by any administrator upon discovery. Admins applying such sanctions should confidentially notify the members of the Arbitration Committee of what they have done and why.

As you can see, the prohibited behavior very much falls in an entirely different camp from anything I’ve ever written regarding you and JimWae (particularly JimWae). In each case, my criticism has been about behavior and skills of the author. While, he might not like it, life does not entitle you to be free of criticism—especially when your behavior is clearly outlandish and provocative; people need to have a thicker skin than that. I don’t know if JimWae is accustomed to having teachers tell him he’s done good work when he really hasn't but he won’t get false self-esteme-boosting praise from me. Also, when you falsely state that a consensus has been reached and start to act on it, again, I’ll call you out on such a stunt. It was a cheap shot and you know it. Greg L (my talk) 02:38, 2 September 2007 (UTC)

• I deleted the Request for Comment template on the Kilogram talk page because, after I did the Request for Comment, I tried to be active on RfC, and I noticed lots and lots of old RfCs. I was going to other pages and deleting old RfC templates, and I figured it would only be consistent to delete the RfC on the kilogram page once it got old.

* You may have many reasons for deleting the RfC. However, the below-quoted text is your stated reason for doing so that you posted on Talk:Kilogram page:

I am removing the Request for Comment template because we haven't gotten any new comments in three days, and Misplaced Pages:Requests_for_comment/Maths,_science,_and_technology really doesn't appear to be a very lively place; other RfCs there are also only netting one or two outside editor comments.

and you also summarized the results as follows…

We haven't come to a consensus on where mass versus weight and the issues of massing should be.

Greg L (my talk) 23:33, 2 September 2007 (UTC)

If you want the RfC to be active again, just write another RfC. It would have been constructive and reasonable for you to have re-opened the RfC at that time, and I would have appreciated it much more than you just ignoring the RfC. I honestly did not believe that we would get any other comments, from looking at other RfCs and how many comments they get. I'm very sorry you interpreted my action as trying to ignore your viewpoint. It was not my intention. I was very disappointed that you didn't reply to my original summary of the RfC, and I'd still like you to do so. I did not try to make up a consensus where there was none.

My interpretation is that the RfC did establish a consensus that mass v. weight should be in one common article, and not in articles devoted to particular units of mass.

My interpretation was also that RfC did not ADDRESS the issue of WHERE mass v. weight should go (and therefore there is no consensus on the issue), so I asked in talk:weight. I would greatly appreciation your views on where the single, common treatment of mass v. weight should go. I can't see how it's any cheaper for me to ask people where mass v. weight should go than for you to continue adding to mass v. weight on kilogram. We are both trying to move forward. I think I'm trying to move forward with the consensus, you appear to think that there is no consensus so you should just ignore the opinions of others editor. Maybe neither of these approaches are correct, but I'd love to hear a suggestion for a new approach.

You've said you care about kilogram because students will actually use the article. I care about the article for about the same reason; it's a really important article that people will read. I think it's really, really sad that process such as RfC and asking questions on the talk page are not getting a large number of interested editors. But, instead of giving up, I think that means that kilogram needs interested editors like you and I, and that we need to find a way to agree. It is not finding a way to agree for you to tell me and other editors that we should just stay away from the article because we disagree with you. That approach; that if someone disagrees with you, they should simply stop editing the article (and you should keep editing the article) is what bothers me, and what makes me think of WP:OWN.

Unfortunately, the wikiquette alerts are, much like RfCs, totally volunteer based, so it probably won't help us straighten this out at all. Which leaves it to us to be mature and cooperative.

I couldn’t be more pleased to hear that! Greg L (my talk) 00:08, 4 September 2007 (UTC)

…I'm trying, and I can see that I'm not succeeding at avoiding pissing you off. I don't know how to be more polite and more constructive than I have been. If you have any honest, polite advice I am very willing to listen to it.

I know how to leave the article, but I honestly think that would be a disservice to the article; it needs more attention, not less. Your edits (like all edits of Misplaced Pages) have been helpful in great part by sparking other people to improve them, and if you chase off everyone else, the article will not be as good as it could be. Enuja (talk) 22:56, 2 September 2007 (UTC)

Gad! Talk about “not being able to let go.” The article has grown. Stop whining about how you can’t get your way and start making good-faith edits. I haven't seen much of the kind of work you can do because it relies too heavily upon the delete key. I've corrected an error in kilogram this afternoon and added a section with photo links. Enjoy. Greg L (my talk) 23:04, 2 September 2007 (UTC)

I can't make good-faith edits (which, to me, mean collaborative editing) to kilogram until we have a consensus about what should be in the article. Since you say we don't have a consensus, I can't edit. Enuja (talk) 23:10, 2 September 2007 (UTC)

Hello. I've nominated Image:CGKilogram.jpg, which you created and uploaded, to Featured Picture status. I think it's a great image that adds a lot of value to the kilogram article. I can't believe you created such an incredible image :-) You may find the nom at Misplaced Pages:Featured picture candidates/Computer-generated kilogram, where you may correct my nom, if you wish, as I copied it from the image description page and, not having used the metric system in my entire life, don't know if there's something wrong or incorrect. Keep up the good work! --Agüeybaná 23:31, 18 September 2007 (UTC)

Discussion style

About one phrase you left on various talk pages (including mine): How can anyone have such a dramatic, 180° change of heart? -- maybe you are assuming too much about peoples (hidden) motives. From the tone of your earlier comments, it appears to me that you saw the nomination for deletion of Template:SI multiples almost as a personal attack, while I was merely expressing my doubt that it served a purpose. I did explain on Talk:Kelvin#SI prefixed forms of kelvin that I wanted to see a consensus about whether to keep these tables in various articles, and there was clearly no consensus for deletion. For me it is not a "dramatic change of heart"; I don't think it would be good if I became very emotional about minor disputes. I don't know you personally, but from the way you respond to me and to others on various talk pages I have the impression that you do often get more upset than necessary. Maybe you are never upset at all, but then be aware that your writing style could give a false impression. Han-Kwang (t) 10:15, 28 September 2007 (UTC)

• I am not upset. Nor did I see your nomination for the SI template as a "personal attack". Not in the least. I don't even like the SI templates since they generate inferior-looking tables. I saw your nomination to delete the SI table template for what it was. First, you deleted an SI table, then, when I restored it, you tried to delete the template that made it. Am I missing anything here? I don't think so. Notwithstanding the general rule that editors should embrace the Misplaced Pages's wholesome, politically correct notion of "assuming good faith with other’s actions", no one has to suspend common sense. Your prior writings and actions would make your intentions abundantly clear. So don't try to hide behind the apron strings of my "discussion style". That is a metric ton of weapons-grade bullionium and I'll have none of it. Greg L (my talk) 17:55, 28 September 2007 (UTC)
