Talk:Conserved current

message: I believe this is a very important topic, but... What does the symbol "j" mean, what does the symbol mu mean, etc. Can whoever wrote this please take some responsibility and define the terms they used, this is supposed to be an encyclopedia, not a document containing undiscoverable terms represented by single characters that have many different usages in different contexts. If this author defines the meaning of these terms in words then they can be hyperlinked to other references in Wikipedia. Without that, the article is only of use to people who are already familiar with the concepts, surely Wikipedians deserve more than this? If the original author of that section is not available, it would be great if anyone else who is familiar with the terms could define them, as is now becoming de rigeur in all Wikipedia articles - jjalexand  —Preceding unsigned comment added by 119.12.66.203 (talk) 14:38, 18 June 2009 (UTC)
thread_title: Please define the symbols

message: Someone, (not me) added merge templates to these two articles. They did not cite any reason for thye merge proposal, so let me provide those words. Besides overlapping with each other, both overlap somewhat with the article charge (physics). My knee-jerk reaction is that the merge proposal sounds reasonable, although I get the feeling that perhaps the wisest choice is to redirect both of these to Noether's theorem. However, leave charge (physics) alone: that deals with a bigger set of topics and issues than merely conserved quantities. (viz it goes into the virasoro algebras and into operators, etc. which these articles don't get into, and which are inappropriate for Noether's theorem) 03:56, 31 August 2016 (UTC)
replies: text: Oppose the idea of merging all to Noether's theorem on the grounds that a conservation law is a better commonly understood that Noether's theorm. Oppose also the merge of the current and quantity pages as there are aspects of the current page with are distinct and, I feel, distinctly notable. The direction of the proposed merge also surprises me, as quantity seems more fundamental than current. Overall, I see no point in the merge. Klbrain (talk) 21:48, 29 April 2018 (UTC)

Talk:Correlation dimension

message: I've just read the original 1983 paper, and noticed that the wikipedia definition is about finding the number of pairs separated by an amount "less than or equal to distance epsilon", whereas the 1983 definition just uses "less than" (i.e. equality doesn't count). It's a very minor point but I thought it worth noting just for future editors' reference. I'll change the article to reflect this. --mcld 21:33, 17 July 2007 (UTC)
thread_title: "less than or equal" should be "less than"

message: Can someone knowledgeable comment on how correlation dimension is defined?
So if I understand the article correctly, correlation dimension is defined only in the following case:
"If the number of points is sufficiently large, and evenly distributed, a Log-log graph of the correlation integral versus \varepsilon will yield an estimate of ν."  Right?  141.214.17.5 (talk) 16:36, 17 December 2008 (UTC)

thread_title:  N*N or N*(N-1) 

message: The article gives a vague definition of ν. For example, what object is ν a property of? Is it
:    1) A sequence of N points?
:    2) An infinite sequence of points?
:    3) An infinite sequence of samples of a probability distribution?
:    4) An infinite sequence of samples of a probability distribution supported on a fractal?
If so, is it a property of the fractal? The language used suggests each of these at various points.
In general, the language of the article is sloppy. 
For example, it says "The technique can be used to distinguish between (deterministic) chaotic and truly random behavior". What technique? A number is not a technique.

Talk:Counter-electromotive force

message: Isn't it possible for a better example of back EMF? The one given of an electric motor in a car is terrible.  It asks the reader to note the change in the idle speed of the (gasoline) engine when using the car window actuator. Many cars won't respond this way as the idle speed is controlled independently of alternator loading (e.g. Prius) or the current drain is too low for the alternator to even notice (e.g. trucks).

Talk:Brutus de Villeroi

message: The article makes this claim:
In 1842, de Villeroi was reputedly a professor for drawing and mathematics at the Saint-Donatien Junior Seminary in Nantes, where Jules Verne was also a student, leading to speculation he may have inspired Verne's conceptual design for the Nautilus in Twenty Thousand Leagues Under the Sea; however, no evidence for Villeroi's employment at Saint-Donatien has yet been found, and no direct link between the two men has ever been established.
Vern himself says he was inspired by the design of the Plongeur, A model of Plongeur was displayed at the 1867 Exposition Universelle, where it was studied by Jules Verne,[6] who used it as an inspiration[7][8] and 3 years later published his novel Twenty Thousand Leagues Under the Sea.[9] Since this article goes on to say that there's no actual evidence that de Villeroi influenced Verne I would argue for removing this paragraph.

thread_title:  concrete example 

message: I offer a very simple explanation: The heat capacity of the Ising model is not the isochoric heat capacity, for the Ising model does not have a volume as a parameter. The C of the Ising model is a heat capacity under the constraint that the “exchange reaction” spin-up ↔ spin-down is in a kind of chemical equilibrium. The equivalent of a real fluid would be an Ising model where the spin-up/spin-down ratio is fixed.
Thermo53 (talk) 20:30, 7 April 2022 (UTC)
replies: text: When you say Ising you mean O(2) right? Will if you publish a paper where you show that this particular effect explains the discrepancy quantitatively? Personally I am skeptical. The effect you are mentioning is well known as "Fisher renormalization of critical exponents". If you do a liquid Helium experiment at constant pressure it should theoretically give the same result as lattice O(2) model. Has been shown in many papers in the 1970s.

Talk:Erik Johan Stagnelius

message: What the fuck?
"His mystical lyrics, entitled Liljor i Saron ( Lilies in Sharon ; 1820), and his sonnets, which are best read in Swedish, may be recommended as among the most delicate products of the Scandinavian mind." Recommended by who? Why? Jesus... "Among the most delicate products of the Scandinavian mind?" Err.. What the fuck?
: As peculiar as the passages sound, they actually come from the renowned EB 1911. The passage in full reads:
:: "Second only to Tegner in genius, the brief life and mysterious death of Erik Johan Stagnelius (1793-1823) have given a romantic interest to all that is connected with his name. His first publication was the epic of Vladimir the Great (1817); to this succeeded the romantic poem Blanda. His singular dramas, The Bacchantes (1822), Sigurd Ring, which was posthumous, and The Martyrs (1821), are esteemed by many critics to be his most original productions. His mystical lyrics, entitled Liljor i Saron (" Lilies in Sharon "; 1820), and his sonnets, which are the best in Swedish, may be recommended as among the most delicate products of the Scandinavian mind. Stagnelius has been compared, and not improperly, to Shelley.' Erik Sjoberg, who called himself " Vitalis " (1794-1828), was another gifted poet whose career was short and wretched. A volume of his poems appeared in 1820; they are few in number and all brief. His work divides itself into two classes - the one profoundly melancholy, the other witty or boisterous. Two humorous poets of the same period who deserve mention are Johan Anders Wadman (1777-1837), an improvisatore of the same class as Bellman, and Christian Erik Fahlcrantz (q.v.; 1790-1866)."

thread_title:  Desiraju citation 

message: The organization of the current article would benefit from a logical progression of ideas in order to make the article more cohesive. For example, crystal engineering can be approached from features at range of length scales, such as molecular structure, intermolecular interactions, crystal structure, and bulk properties. The organization and sections of the current article make it difficult for novice readers to understand the relationships between these topics and how to apply them to materials design. Additionally, the sections of the current article do not clearly outline the design process for crystalline materials or rationalization of their properties using crystal engineering principles, which is the overall goal of the field. 
I’m proposing a new section that will guide a reader through the origins and characterization methods for the mechanical properties of a crystalline material. Providing information about the 3 origins of mechanical properties (intermolecular interactions, crystal structure, and lattice defects) will help a reader make connections between observable properties and features at a range of length scales. If a reader can understanding the underlying mechanisms for these properties, they will have a strong foundation for designing a crystalline material with a targeted property. Moreover, an overview of methods for characterizing mechanical properties may help readers understand the results and discussion of journal articles on this topic. The sources I plan to reference come from recent influential studies, reviews or perspectives from leaders in the field, and textbooks. These resources will offer readers a more thorough introduction to designing and understanding the mechanical properties of crystalline materials. Bahanabread (talk) 20:19, 28 January 2021 (UTC)

Talk:Wilhelm Stenhammar

message: the list of his compositions at IMSLP suggests - unless (the works without opus number provide no clue here) something is seriously missing...?- that the last 5 years of his life went without much finished work (opus 45 having been finished in 1922). This is not that unusual, I guess, but it would be interesting to know if there was some biographical reason (as with some other composers whose regular work habits were interrupted by life changes short of death itself, e.g. Raff having to adjust to great responsibilities as head of the Hoch Conservatory)- in Stenhammar's case - more teaching?

replies: text: "Town of Winchester, Ontario ambulance dispatcher Zenith 9000" does look questionable as it's not the same length as the others. This should have "zenith" followed by a five-digit number. The numbers only covered a specific regional area (as the recipient of these operator-assisted collect calls wouldn't want them coming from all over in that era of expensive long distance service) so it's possible that the same number dialled from some other region might not give the same result. All thoroughly obsolete by now in any case. K7L (talk) 07:04, 24 December 2012 (UTC)
replies: text: When I was growing up in Ontario, all Zenith numbers had five digits. Then when I acquired a Yukon telephone directory in 1976, I found that it had four-digit Zenith numbers for use within the company's operating area. From that, I made the assumption that four-digit numbers were only issued for local companies in the Yukon for receiving calls within the operating area of that phone company (Yukon, western NWT, northern BC). It is also possible that each company fashioned Zenith numbers appropriate to the presence or absence of usage across company territory boundaries. Yukon/western NWT/northern BC did not get access to 800 service until 1984, and the ability of northern businesses to have their own 800 numbers until 1987, so Zenith remained vitally important long after other company territories began migration to 800 services.
