Combined Cycle
I just reverted your deletions, because there was no explanation in the edit summary, plus you removed things that certainly can't be removed (like translations and categories). At least some of the material you removed appears to be reliably sourced. If there was some justification for your removal of sourced material, please explain on the article's talk page. Qwyrxian (talk) 07:03, 17 August 2010 (UTC)


 * Thank you for catching that! It was a mistake - not sure exactly what I did, but removing material wasn't my intention.  I guess I thought I was only editing a section when in fact I edited the whole article (?) and somehow didn't realize that Dhollm (talk) 07:06, 17 August 2010 (UTC)

Reviewer permission
Hello. Your account has been granted the "reviewer" userright, allowing you to review other users' edits on certain flagged pages. Pending changes, also known as flagged protection, is currently undergoing a two-month trial scheduled to end 15 August 2010.

Reviewers can review edits made by users who are not autoconfirmed to articles placed under pending changes. Pending changes is applied to only a small number of articles, similarly to how semi-protection is applied but in a more controlled way for the trial. The list of articles with pending changes awaiting review is located at Special:OldReviewedPages.

For the guideline on reviewing, see Reviewing. Being granted reviewer rights doesn't change how you can edit articles even with pending changes. The general help page on pending changes can be found here, and the general policy for the trial can be found here.

If you do not want this userright, you may ask any administrator to remove it for you at any time. HJ Mitchell &#124;  Penny for your thoughts?   15:05, 17 August 2010 (UTC)

Maxwell's thermodynamic surface and timeline
Since the timeline contains no referenced material, it was IMO simply confusing. I think the timeline should be significantly improved before creating multiple links to it (template boxes are a very high-profile form of linking, and should not IMO be overused). I agree that a future link to a better timeline would be beneficial. -- Radagast 3 (talk) 21:46, 18 August 2010 (UTC)

Pension
I removed a lot of duplicate links from the article; the Manual of Style for links indicates that things should only be linked once. The "See Also" link removals were in error - I added them back, thanks for catching it. Although, unless there is a strongly compelling reason to have those links in the See Also section it is MOS policy not to have them there (as they are linked in the article) --Errant Tmorton166(Talk) 21:51, 18 August 2010 (UTC)
 * On reflection I decided to remove the duplicates in See Also altogether - none of them are particularly significant as see also topics considering their linkage elsewhere in their body :) (if you want to put them back I won't complain though) --Errant Tmorton166(Talk) 21:54, 18 August 2010 (UTC)
 * If they were duplicates I guess that makes sense in general, but I think see also needs to be a list of links to be usable. Thanks! Dhollm (talk) 21:55, 18 August 2010 (UTC)

Rheology
Hi David - it happened because as part of its general fixes, AWB automatically unmakes any self-referential links. Sorry for unintentionally causing some disruption, but I wonder if the design of the template needs to be modified - there's pretty much guaranteed to be trouble when a behaviour of the template can be influenced by some apparently unrelated factor. Colonies Chris (talk) 08:32, 31 August 2010 (UTC)
 * Thanks for your reply. I agree with you about the template; but it is very widely used (derives from Template:Physics navigation) so I doubt it could be easily fixed. I'm not familiar with AWB but could automated edits (if that's what they are) be tuned to ignore anything in a template? (Maybe that would cause more problems?) David Hollman (Talk) 08:36, 31 August 2010 (UTC)

Thermodynamic energy
FYI: As far as I can tell thermodynamic energy is a term used mostly in atmospheric science. If you search for it in this paper, for example, you will find it all over the place. I'm still trying to figure out exactly what it means, though. So far I get the impression it may be a little broader than thermal energy but a little narrower than internal energy, as is described here. However, I'm not going to be offended if the page is deleted; as I might never actually get around to clarifying what it is! (If I do, I can always just make a new page...) Riick (talk) 19:50, 1 September 2010 (UTC)


 * I get the impression from that paper and from Googling that it is used nearly synonymously with internal energy; but I haven't seen anyone define it carefully. In any case, the reason I suggested deletion was because there were no links to that page, and so it just seemed superfluous.  David Hollman (Talk) 21:25, 1 September 2010 (UTC)


 * OK. Riick (talk) 21:45, 1 September 2010 (UTC)


 * Well the delete got denied anyway, and I guess for a good reason! Oh well... David Hollman (Talk) 22:15, 1 September 2010 (UTC)

Proposed deletion of Physics/Theories

template use
Hello, just for info that template Machine configurations redirects to template heat engines, so you added some double templates --Typ932 T&middot;C 20:09, 12 September 2010 (UTC)
 * I did notice the redirect but missed the cases where the template was not at the bottom of the article (ie in see also sections). Sorry about that, but thanks for picking up on it and fixing!  I'll look out for that in the future.  David Hollman (Talk) 20:13, 12 September 2010 (UTC)

Trying to contribute...
GortGetsGoing (talk) 17:31, 13 September 2010 (UTC) Not sure why every time I add unbiased content that has third party backing, it is deleted. Some help here? Please. Thank you! The content I added to mechanical bearings was legitimate info from an engineering publication? I appreciate your help.


 * I'm sorry if my edit seemed overly harsh; I should have taken a moment to explain my reasoning (although since the edit was made not-logged in, I didn't think to write on your IP address's talk page).  The reason I felt it was inappropriate was because it appear to be from a source which was self-promotional.  Also Wikipedia guidelines requires "notability" and material from a primary source (ie the company itself) doesn't necessarily fulfill that criterion.  (You can read more about some of these topics on WP:Notability and Spam may also be relevant).


 * I'm not, however, claiming that these sorts of decisions are infallible; others might disagree with my interpretation. I suggest if you want more input on whether or not the text you added is acceptable (or how to make it so) you can also post on the talk page of the article;  anyone interested in the article can then give you their opinion.


 * I do hope that is helpful; contributions to WP really are welcome and I'm sorry if I've put you off at all!  Let me know if I can help with anything else. David Hollman (Talk) 18:41, 13 September 2010 (UTC)

Pending changes/Straw poll on interim usage
Hi. As you recently commented in the straw poll regarding the ongoing usage and trial of Pending changes, this is to notify you that there is an interim straw poll with regard to keeping the tool switched on or switching it off while improvements are worked on and due for release on November 9, 2010. This new poll is only in regard to this issue and sets no precedent for any future usage. Your input on this issue is greatly appreciated. Off2riorob (talk) 23:32, 20 September 2010 (UTC)

Regarding your changes to Entropy page
I would like to find out the reasoning behind deleting my defitinition and then the explanation of entropy in http://en.wikipedia.org/wiki/Introduction_to_entropy

Compare my revision: http://en.wikipedia.org/w/index.php?title=Introduction_to_entropy&oldid=383213883 and yours: http://en.wikipedia.org/w/index.php?title=Introduction_to_entropy&oldid=383322942

The reason behind my explanation was to make the concept understandable:
 * Every time heat flows from a hot spot to a cold spot, entropy increases, as heat becomes more distributed throughout the system. Every time heat flows from a cold spot to a hot spot, entropy decreases, as heat becomes more concentrated in certain parts of the system.

While yours, as it currently stands:
 * In a physical system entropy can provide a measure of the amount of energy that cannot be used to do work.

Is confusing and does not mean anything. Please let me know.

Drozdyuk (talk) 17:24, 25 September 2010 (UTC)


 * I tend to support the former definition of entropy (in terms of heat flow) as more understandable to the novice in the science of classical thermodynamics. But I do not agree with that author that the latter statement (in terms of useful work) has no meaning. To the contrary, the measurement of useful work provides one of the most mathematically fundamental definitions of the concept of entropy. (In fact, the only way to be comprehensive on the subject matter is to provide several different definitions, and preferebaly several examples!)


 * Over time (~ 30 years) I have found that the most satisfactory definition of entropy typically arises from the arguments describing the concepts of irreversible processes. I quote here from P.W. Atkins' Physical Chemistry (5th Edn., Oxford, 1994) which is where I cut my proverbial teeth, before moving on thru such literary classics as Swalin (solid state thermo), Prigogine & Defay (irreversible processes), Van Wylen & Sonntag (for engineering applications), etc. Atkins begins by proving mathematically that a system does its maximum work when it is working reversibly. This concept of maximum work is quantified by the relation:


 * Wmax =  delta U  -  T delta S


 * This expression shows us that in some cases, depending on the sign of the final term, not all the change in internal energy may be available for doing work. I.E. In order for the change to be sponaneous, some of the energy must be dissipated -- or escape as heat. Thus, Nature is demanding a sort of 'tax' on the internal energy U as it is converted into useful (atomically directional) work. I.E. Because chaotically stored (atomically disordered) energy cannot be used to achieve uniform motion in the surroundings, only the portion of U that is not stored chaotically (U - TS) is available for conversion into useful work.


 * Thus every irreversible process has associated with it a net increase in entropy which inevitably results in a certain amount of lost energy -- that is, energy that is unavailable to do useful work. In my humble opinion, the best definition would include all of the above, in addition to a statistical approach to the definition of entropy. Who is to say whose is better ? The most satisfying part of this approach to me over time is to learn repeatedly that they all resonate nicely with one another :-)- logger9 (talk) 04:50, 17 October 2010 (UTC)

Hello. Can you provide a link to the exact diff you are referring to? I don't quite see where that change was made. My edits on Sept 6th were mostly to restore some text that another editor deleted. Compared to your edits on July 15, the wording is still pretty similar.

Thanks, David Hollman (Talk) 09:19, 26 September 2010 (UTC)


 * Hello, sorry for getting back to you so late - but I can never keep track of my wiki changes :-( Anyways, here is the change I am referring to (first paragraph), in which I tried to get rid of the wording like "amount of energy that cannot be used to do work".

Template:Thermodynamics philosophical context
Hi, the TfD discussion closed just after I snuck in another comment, so I was wondering what you thought of the hatnote-style versions I created in the sandbox? PC78 (talk) 15:11, 29 September 2010 (UTC)

Copyright?
Hello! In regards to this edit to the Harlem River article, I can't find where on the referenced site the students' papers were released under free licenses. In fact, on the higher level pages in the domain I find strict copyright notices in the page footers. Can you help me out with finding where the free license for the material is so we can properly cite it in the article? Thanks! &mdash;Elipongo (Talk contribs) 19:57, 3 February 2011 (UTC)


 * Sorry for the long delay in replying, I hadn't logged into WP in a long time. Anyway, I had added some citations to those changes, although they might be incomplete and there certainly may be room for additional or improved ones.  I do recall wanting to do further editing / consolidation / etc. to that text but not having the time to complete it;  though being almost a year ago I don't remember exactly where I left off / what was actually accomplished.  I did not mean to leave the article in a state where a lot more improvement is still needed, in hindsight maybe I should have left it in a sandbox until I had more time to deal with it. dhollm (talk) 21:01, 12 July 2011 (UTC)

Copyright: Copying within Wikipedia
Hello, Dhollm. I can see that you've done a great deal of work organizing material in science spaces. I'm sure that if you'd like to become active again, there's still much that could be done. I do need to make sure, though, that you're aware of the policies regarding copying content from one article to another. A user who left a note above brought up copyright concerns with your articles in November of 2019, and what I have discovered is primarily a habit of moving material around. When you do this, it is mandatory that you at minimum name the article you are moving content from into the edit summary of the article you are moving content to. I see that you have sometimes done this, but inconsistently. There are additional best practices described in Copying within Wikipedia which I'd also ask you to follow, should you continue this practice. This is important because content on Wikipedia is not public domain. It is released under a liberal license that is voided if the terms of attribution are not met. Because of this, when we do not provide attribution, content moved from one article to another becomes a legal problem. I'm in the process of retroactively correcting this where I discover it in your contributions, so this is a request for any activity going forward. Thanks. --Moonriddengirl (talk) 12:00, 18 June 2020 (UTC)
