I'm interested in the example I understand that the dish is perfectly configured for a trajectory in a horizontal plane, but I'm uncertain that the centrifugal force is entirely eliminated for paths that are not in the horizontal plane. What is your take on this? Brews ohare ( talk) 03:31, 14 June 2008 (UTC)
Thank you for your August 2003 Woodstone TALK, and your illustrations here. Analog Science Fiction ran a delightful story of an astronut stuck on a parabolic mirror that perhaps you wrote. Anyway, to me L = Iω = El (god). Pawyilee ( talk) 10:51, 19 December 2008 (UTC)
Hello Cleonis,
I am unclear why you reverted my edits, you cited that "quality and performance are degraded"? I have no idea how a thumb can degrade quality and performance. I was about to place a delete tag on your 256x256 images per Wikipedia:Criteria_for_speedy_deletion#Files item 1, which clearly indicates that "performance" is degraded by having duplicate files! The thumbnails are cached copies, generated via imagemagick convert. These cached images can be clicked on by the reader to view the full 512 by 512 image as desired. Keeping multiple images is against current policy.
Also, execpt for the dangling line, I thought the layout was neater. I would like to revert it back to the version that I changed it to, but I shall await your reponse.
Kind regards, User A1 ( talk) 09:51, 12 April 2009 (UTC)
Hello, I see you restored the EJS article on Easy Java Simulations. I'm just dropping by to let you know why I redirected it to Open Source Physics, and give some suggestions on how to make sure the article sticks around for the long term.
I turned the article into a redirect because that is what happened to an earlier version of it at "Easy Java Simulations". I don't know if you've noticed, but that article was deleted twice last year (once for being "blatant advertising, used only to promote someone or something", later for "promoting a non-notable software application"), restored twice, and eventually turned into a redirect to Open Source Physics. Since both articles were in similar condition (the one deleted last year was longer and cited a few more sources), I had both redirect to OSP.
Now, as for how to make sure it doesn't get deleted (or turned into a redirect again). First of all, the article itself should be moved to "Easy Java Simulations", and "EJS" should redirect to that title, not the other way around. That way, people who might not know what "EJS" stands for can get some idea of the article's content from its title (for more discussion, see the manual of style).
Most importantly, I note that there are no references to third-party sources that establish the notability and importance of the topic (much the same goes for the Open Source Physics article). The best way to establish the article's notability is to add references to scientific, trade-journal, or newspaper/magazine articles describing the use of EJS and its benefits to research or teaching. I'll add some templates to the article to encourage others to help out. If nothing of this sort can be found, I may convert the EJS article into a section within the Open Source Physics article. I think such expansions would work well for each of the four OSP projects. Cheers, David Schaich Talk/ Cont 03:03, 24 July 2009 (UTC)
I have been looking at wikipedia entries for other software packages with comparable purposes. EJS is:
There is the
List of numerical analysis software. All of the entries on that list are wikipedia articles. It seems to me that quite a few of the entries there are less notable than EJS.
An
article dedicated to Easy Java Simulations was published in
The Physics Teacher, a magazine that is published by the
American Association of Physics Teachers.
{{ Numerical_analysis_software}}
In all I find it puzzling that the
Easy Java Simulations article is challenged as to whether EJS is notable. As far as I can tell articles about less notable software have not been challenged. --

I've taken the very great liberty of moving this to introduction to angular momentum.
It seemed like a reasonably good start for that. Hope you don't mind. We can always undo it if you do.

hello cleonis. i saw this great animation in the english wiki, and became jealous. i want to use it in the hebrew wikipedia. is this possible? can you upload it to wikimedia commons? if not- can i use it? what kind of liscence does it have? thank you: בלנק ( talk) 17:43, 2 November 2011 (UTC) (blanc)
Hello,
I just read your translation on Einstein's 1905 paper on light quantization, http://en.wikisource.org/wiki/On_a_Heuristic_Point_of_View_about_the_Creation_and_Conversion_of_Light. Thank you! It was very helpful, but I think the first two equations under paragraph 138 need to be corrected:
In the source that you used, http://www.zbp.univie.ac.at/dokumente/einstein1.pdf, the first two equations on page 7 of the pdf document seem to refer to trying to determine when the entropy is 0. Since dS = T dE, it looks like in the first equation Einstein is setting dS = 0, and in the second, he is saying that this is equivalent to setting dE = 0. So since S = volume * (integral of phi with respect to nu), setting dS = 0 means setting the partial derivative of (integral of phi with respect to nu) equal to 0. So in the first equation, the first symbol should be a "d," not a "rho." And in the second equation, since we want dE = 0 and E = volume * (integral of rho with respect to nu), then it should read d(integral of rho with respect to nu) = 0.
Other than that, this translation looks good. Thanks again! — Preceding unsigned comment added by 96.245.107.49 ( talk) 00:23, 15 August 2012 (UTC)
