Talk:Ponderomotive force

message: Looking at [one of the original papers], I find essentially the same equation with a factor 1/2, not 1/4 as in the first paragraph of the Wikipedia article. What is correct? -Anastasius zwerg (talk) 15:56, 27 October 2008 (UTC)
replies: text: Sorry, not really problem; I got it in the meanwhile: it is 1/2 with the time averate for E^2, but 1/4 with the amplitude E_0 for a field varying like E_0 \cos \omega t. --Anastasius zwerg (talk) 16:17, 27 October 2008 (UTC)
thread_title:  Factor 1/4 ok? 

message: Although the article defines ponderomotive force as involving a "charged particle" perhaps the definition might be clarified in considering that "weak forces on neutral atoms in inhomogeneous light fields may arise from the dynamical polarization of an atom" and can produce "previously unconsidered extremely strong kinematic forces on neutral atoms in short-pulse laser fields."
By the way, Eichmann et al. touch on Paul traps and the Kapitza–Dirac effect, which ought also to be mentioned in the Wikipedia article on ponderomotive force. This is way beyond my ken, but perhaps someone could manage all this. Myron (talk) 00:29, 30 October 2009 (UTC)
thread_title: Ponderomotive force can affect a neutral particle

message: hello, the fact that ponderomotive force increases while the frequency decreases suggests that it is not valid on low frequency. otherwise it would become infinite with a... static force. Am I wrong?Klinfran (talk) 21:04, 2 August 2010 (UTC)
thread_title:  frequency 

message: The page is badly missing something on the history of the term ponderomotive force. Originally it meant a force that acts upon matter with weight. So gravity was considered a ponderomotive force, for example  — Preceding unsigned comment added by 82.24.86.223 (talk) 22:31, 3 September 2011 (UTC)
thread_title:  history 

message: It seems that some inconsistent terms are used in the derivation section (version accessed 22 July 2013). The "equation of motion" becomes "the force equation"; x is both a variable indicating position and a "motion" that can "oscillate".  At graduate level we grow accustomed to this kind of thing, but should this be written in more accessible form?

thread_title:  Loose/confusing terminology/jargon in derivation section? 

message: The given equation for Ponderomotive force does not take the direction of the electric field into account. \mathbf{F}_{\text{p}}=-\frac{e^2}{4 m \omega^2}\nabla(E^2)
However, the derivation relies on the oscillations being in the same direction as the gradient. --68.5.67.232 (talk) 20:15, 29 September 2020 (UTC)
thread_title:  Derivation only works when the oscillations and gradient both point in the same direction. 

message: I just added an etymology section. It is because I am learning what ponderomotive is and I had no idea what the term meant, so I added the section. TheRealBalalaikaMaster (talk) 22:03, 27 September 2023 (UTC)

Talk:New Labor Forum

message: I addressed the notability and third-party references concerns in a couple of ways.  First, I linked to some of the names of authors who recently published in the journal.  Notable people writing for the journal should help to establish notability.  Second, I added the names of some of the editors of the journal.  Notable people on the editorial board should also help establish notability.  Third, I added citations showing how the journal has played a major role in a well-known (within the labor studies community, anyway) and controversial labor studies conference, how notable new authors are playing up their participation in the journal, and the opinion of at least one editor of a major political magazine (vanden Heuvel at The Nation) considers the journal important.  Lastly, I also cleaned up the article, restoring the categorization and removing much of the advertising-like language. The addition of citations and notability should raise the article to Start class for the Organized Labour Project. - Tim1965 (talk) 17:11, 13 July 2008 (UTC)

message: Judicael ap Hoel is not the  of this figure. Moreover, he was a medieval Breton, not a modern Welshman, and there is no sensible reason to use the modern Welsh form of his name as a dab from the other Judicaels.

message: This article seems to merge Australs and Asian Parliamentary debating into one format. I'm not sure if they were historically the same, but any current Australian or Asian debater would definitely treat them as two different formats (the biggest difference being that Australs has 8-minute speeches with no POIs, while AP has 7-minute speeches with POIs). There are also differences in scoring. In contrast, I've never heard the blanket term "Australia-Asia debating" - they are treated as two separate formats, not one. I think this article should be split into two to reflect this - if no one has objections, I'll start looking for reliable sources that I can use to build the new article (with the caveat that I'm less familiar with Australs than AP, so it would be good if somebody familiar with that format could work on that side of things).
