Talk:Chua's circuit

If hundreds of papers have been written on the subject, why is this a stub? —Preceding unsigned comment added by 198.209.58.47 (talk • contribs)

I would expand it, but I don't have time to learn chaos theory. Here's the list of papers. - mako 20:11, 28 February 2006 (UTC)

locally active resistor

What is a "locally active resistor" ? How is it any different from any other resistor in this circuit? --68.0.124.33 (talk) 17:01, 17 October 2008 (UTC)

I think the distinction is that it's a "resistor acting as a resistor", rather than a "resistor being part of a nonlinear component". - mako 23:30, 7 February 2009 (UTC)

Various attractors in Chua's system

To date, а huge number of various types of chaotic attractors in Chua's system have been discovered. (Bilotta, E., Pantano, P., Gallery of Chua Attractors, World Scientific, 2008, isbn=978-981-279-062-0), (Leonov G.A., Kuznetsov N.V., Vagaitsev V.I, Localization of hidden Chua's attractors, Physics Letters A, Vol. 375, is. 23, 2011, pp. 2230-2233 ).

Coexistence of attractors in Chua circuit. Two trivial attractors coexist with one hidden periodic attractor and two hidden chaotic attractors.

I have found that the figure with coexisting hidden Chua attractors was chosen for the cover page of the International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, volume 27, number 12, 2017:

Hidden Chua attractor exists: circuit realization and experimental observation (Kuznetsov N.V., Seleznev E.P., Stankevich N.V. 2020).

What is the practical use of this?

Is this just a dorky academic thing? Leon Chua is the memristor guy right? Anything to do with that? — Preceding unsigned comment added by 2602:304:47EB:72C9:21B:77FF:FEAD:46DE (talk) 22:53, 24 June 2012 (UTC)

Shrees1234 recent additions

User:Shrees123, I'd like to explain why I reverted your well-intentioned and knowledgeable additions to the article:

• The excessively mathematical description of chaos in general was not appropriate for the introduction, because the introduction will be read by people without a technical background and should use nontechnical language if possible, and also because this article is about Chua's circuit specifically and not chaos in general.
• The section title "Introduction" placed at the top does not comply with WPs article format given in the Manual of Style and breaks the article format. The first section is automatically the introduction and does not need a section title.
• The section on "Harmful" and "Harmless" effects, while interesting, again is too broad in scope, covering chaos generally while this article is about chaos in electrical circuits. I didn't know that chaotic circuits have practical applications in electronics, as you mentioned. If you want to add a section about that, I think that would be a great addition to the article.

I think the link to the page on how to construct Chua's circuit is good and belongs in the article, although it should not be put in as a Bare URL but should be formatted in a Citation template. I hope you'll forgive my intervention and continue to contribute to the article, you seem to know a lot about this arcane subject, certainly more than I do.

I just removed this

.Wikipedia talk:Articles for creation/Introduction to Chua's circuit I think everyone must have noticed water dripping from a tap,which is sometimes regular and which is sometimes regular and sometimes irregular? Or water flowing through an obstacle in a way that can be either smooth (laminar) or turbulent? At some point in time we all notice these phenomenons, however they are usually very hard to explain. It was only after Edward Lorenz [Lorenz, 1963] came to conclude that his computer simulated weather model is highly sensitive to initial conditions that the scientific community rigorously studied the phenomenon of chaos. However it took more than 30 years to prove that the observations made by Lorenz were indeed chaotic [Tucker, 2000].[1]<ref>ChuasCircuitForHighSchoolStudents-PREPRINT.pdf

That is not well written. Nicoguaro (talk) 16:14, 27 August 2013 (UTC)

I agree. The article doesn't need a description of what chaos is in general, readers can find that at the Chaos theory or Butterfly effect articles. In addition, the contributions of this editor are not complying with the format rules for WP articles (WP:MoS). For example, the lead sentence should be a definition of the subject, with the article title bolded in the sentence (WP:LEAD). The paragraph should not have been added ahead of the article's lead sentence. Also the style of writing, with its questions, is not appropriate to an encyclopedia but more like a textbook. --Chetvorno^TALK 18:51, 27 August 2013 (UTC)

What is the f(x) function in the "dynamics" section?

"The function f(x) describes the electrical response of the nonlinear resistor"

Let's say that if x is the voltage across the negative resistance then the current is I(x). If you derive the first equation you can see that that f(x)=R*I(x). I don't see any reason to incorporate resistance of completely separate resistor into the function describing "electrical response of the nonlinear resistor". Much more sensible approach would be to pull f(x) out of the parenthesis and change it's definition to f(x)=I(x). — Preceding unsigned comment added by 91.237.79.35 (talk) 14:39, 25 December 2021 (UTC)
