Psychodynamics

Do we really need a link to an article on "Freud's Psychodynamic Theory" here? I see the analogy but ... so what? --Christofurio 14:01, 20 April 2006 (UTC)

Christo, from one perspective I can see your point; however, for those interested in the historical development of science, I think it is more than noteworthy to know that an entire branch of science, i.e. psychodynamics and psychology in general, developed in part due to a chance meeting between Hermann von Helmholtz and Ernst von Brucke and Sigmund Freud. All of the following related topics derived out of these interactions:

Psychodynamics

Ego, superego, and id

Psychic energy

Psychodynamic psychotherapy

Freud's Psychodynamic Theory

The Psychodynamics of Political Correctness

Psychodynamics & Large Groups

The Psychodynamics of Serial Killers

And many others, etc. In other words, I find it interesting to know that a large part of the theoretical structure of psychology is based, in principle, on the 1st and 2nd laws of thermodynamics.--Sadi Carnot 13:45, 24 April 2006 (UTC)

It's true that it's an interesting note, but it's interesting in the context of Psychodynamics - that is to say, the interest is really unidirectional. Thermodynamics has nothing tto do with psychodynamics, but pschodynamics has something to do with thermodynamics. It's a tangent that might be mentioned, but having a link with no explanation about the fact that it's not actually physics is not really a good way of dealing with it.

Thanks Gartogg, but I already removed the link back in April. Later: --Sadi Carnot 17:30, 8 November 2006 (UTC)

Bone digester?

Under history, Denis Papin is said to have built a "bone digester". However, the page about him talks about a "steam digester", which seems a much more likely name. Could somebody more knowing than me please fix? --16:25, 29 April 2006 User:85.166.246.162

From what I've read, either term will do; word for word some sources state that Papin's contraption was a: "steam digester used for softening bones". According to my understanding, from a few different sources, people in the olden days wanted to be able to cook bones for dietary purposes. Hence, they built bone, or "steam", digesters to soften bones. Essentially, they were pressure cookers. They may have gone by either name in the past; but bone digesters is referenced more often.--Sadi Carnot 19:22, 29 April 2006 (UTC)

In Lavoisier's 1787 Elements of Chemistry, pg. 28, he refers to it as Papin's digester. --Sadi Carnot 06:58, 26 February 2007 (UTC)

Onsager reciprocal relations

I have seen the Onsager reciprocal relations also referred to as the '4th law of thermodynamics'. Might they be suitable for inclusion in the list? -- Ancheta Wis 21:44, 21 May 2006 (UTC)

This is already mentioned on the laws of thermodynamics page.--Sadi Carnot 23:33, 24 May 2006 (UTC)

Merle Randall

If anyone knows biographical data about this person please add it; I can't find anything on the web, in spite of the fact that Lewis & Randall textbooks are some of the most referenced in thermodynamics? Thanks:--Sadi Carnot 01:54, 27 July 2006 (UTC)

Electrochemical measurements were another way to establish thermodynamic properties. Merle Randall, who came with Lewis from MIT, and E. D. Eastman, an early Lewis student, worked with Latimer in a Gilman Hall laboratory specifically designed for such measurements. This is from the ACS web site. It hardly seems sufficient to add to the article, but it's all I know. Tex 18:28, 27 July 2006 (UTC)

E. A. Guggenheim

Does anyone know anything about E. A. Guggenheim? According to the 2000 textbook Chemical Thermodynamics, by Ott and Boerio-Goates, Guggenheim's 1933 book Modern Thermodynamics by the Methods of Willard Gibbs was one of the two books that founded the science of chemical thermodynamics. I have yet to get a copy of this book; thus, in the mean time, does anyone have any biographical data on this person so as we might start a stub on him (or her)? Thanks:--Sadi Carnot 10:36, 8 August 2006 (UTC)

Found it: Edward A. Guggenheim. Later: --Sadi Carnot 11:41, 29 November 2006 (UTC)

New "Category:Thermodynamicists" started

I collected all of the famous thermodynamicists I could think of (~15 so far) and grouped them here: Category:Thermodynamicists. If you know of more please add them. Thanks:--Sadi Carnot 15:34, 29 August 2006 (UTC)

Magnetic Energy

Magnets are exempt from the laws of Thermodynamics.

A) They generate no heat when their magnetic fields come into contact. B) They lose none of their magnetic force over any span of time. C) There is no heat generated by generating an attraction or repulsion, so any number of magnets are always in equilibrium with each other. D) There is no heat after creating a magnetic attraction or repulsion, thus rendering the magnets ALWAYS at Absolute Zero Temperature even during operation. —Preceding unsigned comment added by 72.142.7.250 (talk • contribs)

Of course, magnets are not exempt from the laws of thermodynamics. --DrTorstenHenning 14:52, 16 September 2006 (UTC)

See: Entropy (order and disorder) it as a magnet discussion (which includes a discussion of the laws). Later: --Sadi Carnot 17:27, 8 November 2006 (UTC)

Magnets are not "exempt" from the law of thermodynamics, because the law covers everything without exeption by definition. Your claim should state that magnets "invalidate" the law. However, magnets would not invalidate the law if their power indeed diminishes, albeit at a rate so small that it cannot be measured with current technology.Gcsnelgar 16:09, 20 January 2007 (UTC)

GA Re-Review and In-line citations

Note: This article has a small number of in-line citations for an article of its size and currently would not pass criteria 2b.
Members of the Wikipedia:WikiProject Good articles are in the process of doing a re-review of current Good Article listings to ensure compliance with the standards of the Good Article Criteria. (Discussion of the changes and re-review can be found here). A significant change to the GA criteria is the mandatory use of some sort of in-line citation (In accordance to WP:CITE) to be used in order for an article to pass the verification and reference criteria. It is recommended that the article's editors take a look at the inclusion of in-line citations as well as how the article stacks up against the rest of the Good Article criteria. GA reviewers will give you at least a week's time from the date of this notice to work on the in-line citations before doing a full re-review and deciding if the article still merits being considered a Good Article or would need to be de-listed. If you have any questions, please don't hesitate to contact us on the Good Article project talk page or you may contact me personally. On behalf of the Good Articles Project, I want to thank you for all the time and effort that you have put into working on this article and improving the overall quality of the Wikipedia project. Agne 00:06, 26 September 2006 (UTC)

Agne, thanks for the tip on the citation need. I added about 13 new citations. If you feel that anything else is lacking just jot me a note. Thanks: --Sadi Carnot 01:09, 5 October 2006 (UTC)

Thermodynamic Software

I think we need to add links to external free thermodynamics software, especially chemical thermodynamic software such as:NASA's CEA, Stanfords STANJAN and Kintecus and any others.—Preceding unsigned comment added by Jianni (talk • contribs) 15:17, 18 March 2007

I notice Kintecus is your program, right? Please see WP:NOT. Wikipedia is not a link farm. If you have a link that adds something specific to the article it can certainly be discussed here, but our goal is not to link to every possible program. U$er 17:33, 18 March 2007 (UTC)
