I think it should be mentioned at least in the introductory paragraph that James c.Maxwell took the first permanent colour photo. Honestly i think that is at least worth a mention. It'd also be fantastic to actually have a replication of it on here, but hey..

[edit] Question about Thomas Sutton reference

I have a question about the reference to Thomas Sutton having made the photographs for Maxwell's 3-color photography demonstration. It has been several years since I read a transcript of Maxwell's report of the experiment, but I don't recall a mention of Sutton making the plates. I'm not challenging the accuracy of this; I just didn't recall it or didn't know it, and I would like to know the source of the Sutton information. It's actually of some consequence, because of questions about the color sensitivity of the plates (see my discussion at http://www.greatreality.com/ColorDidMKnow.htm).

Because this article's history is so long, and I've done very little editing on Wikipedia, I wasn't readily able to learn who submitted the Sutton reference. I would appreciate knowing the source of that information, if that's possible. Please contact me via muser@ecentral.com. (At some time, I do intend to add a few lines about the color sensitivity issue to this article.) Thanks, J. C. Adamson

[edit] featured article candidate

Some things holding back this article from featured article status:

  • 1. It would appear from the title "Later years and afterwards" that the section would relate not only to the last years of Mr Maxwell's life, but also to his lasting legacy and events occurring after his death. Nevertheless, a mere sentence relating to his literary works concerning him appears. Thus, the "Later years and afterwards" section warrants expansion.
  • 2. In the "Early Years" section, the following sentence appears: "The family name Maxwell was adopted by the terms of a legal requirement made upon his father to inherit an estate." The sentence's structure is awkward; furthermore, it does not mention whose estate is to be inherited (an individual from Clerk's maternal family, perhaps?). I would suggest something such as: "When Clerk inherited the estate of name (his relation), he adopted the latter's surname, as was required by the will," or words to the same effect.
  • 3. The article uses single quotation marks instead of double quotation marks.
  • 4. The article contains many unexplained names and terms, such as "elastic solids," "oscillating electric charge," "the progressive condensation of a purely gaseous nebula," "temporary double refraction produced in viscous liquids by shearing stress," and so on. Such phrases are unintelligible to those not well-educated in science. At a minimum, links to articles on such topics should be placed, if not a minor explanation.
  • 5. Unlinked names, including "Herapth, Joule, and particularly Clausius," "Faraday," and several others, appear. Not only should links be provided, but also should one use full names for first references.
  • 6. Several passages appear opinionated (possibly being from the 1911 Britannica): for instance, "valuable papers," "original and powerful essay," "a man whose knowledge was co-extensive with his ingenuity," "most profound admiration and attention," "the ideas of that master," "great treatise," "admirable generalized co-ordinate system," "munificent founder," "distinguished alumni," "excellent elementary treatise" and "great contributions."

I do not ask that all of these be changed, but the level of subjectivity now present must definitely be reduced. -- Emsworth 01:48, Jul 5, 2004 (UTC)

[edit] quaternion equations

I looked at James Clerk Maxwell's "Treatise on Electricity and Magnetism" 1873 First Edition. I could not find the "linked set of twenty differential equations in quaternions". Where are these quaternions?

Please respond to:

dcliffordlee@hotmail.com

James Clerk Maxwell ... a set of twenty differential equations in quaternions. ... Oliver Heaviside enormously reduced the complexity of Maxwell's forty quaternion equations ...

20 or 40 ? Need to go back to the book.

[edit] (Contested -- Jul 4) James Clerk Maxwell

Good article with a good deal of information on his life and discoveries.--Alsocal 20:11, 4 Jul 2004 (UTC)

  • No vote, but the image needs source/licensing information (probably PD as he died before 1923). anthony (see warning)
    • It's a photo. No way it's not PD - David Gerard 21:36, 4 Jul 2004 (UTC)
    • I've marked the photo PD (can't not be) and have added several more - David Gerard 22:03, 4 Jul 2004 (UTC)
    • There are many ways this could not be PD, but whatever. anthony (see warning)
  • Can I second this having worked on it? If so, second. - David Gerard 21:36, 4 Jul 2004 (UTC)

[edit] Controversy about what Maxwell actually did/discovered in electromagnetism

The great problem was that Maxwell produced his equations, then Hertz claimed to have confirmed Maxwell's prediction. When Planck and Bohr later showed that Maxwell's equations were definitely faulty, it was too late to re-examine the theory as the physics has already been dumped (Maxwell had a false aetherial gear cog and idler wheel 'displacement current' mechanism). So Maxwell's equations were labelled classical physics instead of being corrected.

from Nigel cooks website. Why is this not discussed on the page? --Light current 06:26, 21 February 2006 (UTC)

There is no controversy; the “spinning cell” (atom) / “idle wheels” (electrons) model was a conceptual mechanical-like model of how the electrical field lines, magnetic field lines, and currents could operated the way they do in terms of spins, centripetal force, pressures, and tensions. The model is quite ingenious, I must say. Read the following book:

Adios:--Sadi Carnot 16:02, 16 April 2006 (UTC)

[edit] Repeated image

The main image is repeated further down the page. Would it be sensible to remove the second one or replace it?--MichaelMaggs 07:28, 17 June 2006 (UTC)

I've now removed it.--MichaelMaggs 12:52, 5 September 2006 (UTC)

[edit] Cultural depictions of James Clerk Maxwell

I've started an approach that may apply to Wikipedia's Core Biography articles: creating a branching list page based on in popular culture information. I started that last year while I raised Joan of Arc to featured article when I created Cultural depictions of Joan of Arc, which has become a featured list. Recently I also created Cultural depictions of Alexander the Great out of material that had been deleted from the biography article. Since cultural references sometimes get deleted without discussion, I'd like to suggest this approach as a model for the editors here. Regards, Durova 15:44, 18 October 2006 (UTC)
