Talk:Paraxial approximation

message: Regarding: meridional ray and sagittal ray
The geometrical optics problem is often symmetric about the optic axis.  Many planes may be constructed containing the optic axis; only two rays are required to construct such a plane.
For this introductory article, the conventional terminology is ambiguous without chasing several other references.  Please clarify how the distinction of meridional and sagittal rays relates to the accuracy of the approximation.  Ryan Westafer (talk) 23:04, 7 November 2010 (UTC)
replies: text: I'm  not sure what the ambiguity you refer to is. As you note, many planes can be constructed which contain the optic axis. Any ray that lies in any of those planes is a meridional ray. Saggital rays do not lie in any plane that contains the optic axis.--Srleffler (talk) 23:32, 7 November 2010 (UTC)
thread_title:  Clarification Requested 

message: As I understand it, for an idealized finite-sized paraxial lens (e.g., a Paraxial surface in ZEMAX) a given point on the (flat) surface of a paraxial lens changes the angle of the incoming ray by a fixed angle regardless of the angle of incidence. Is that right? If so, I think that angle change is as follows: At radius r from the axis, a paraxial lens of focal length f bends a ray parallel with the axis by \theta such that it hits the optical axis a distance f downstream. That ray intersects the axis with the same angle, \theta. Thus
:\tan \theta = \frac{r}{f}
and so
:\theta(r) = \arctan\frac{r}{f}
and by extension, a ray hitting the paraxial lens at radius r and coming toward the axis with angle \varphi comes out at \varphi+\theta(r). Does that sound right? —Ben FrantzDale (talk) 15:09, 30 November 2011 (UTC)
thread_title:  Angle change? 

message: I don't see mention of how it changes numerical aperture. This is original research, but here's what I got: If you have a paraxial lens with focal length f a distance d from an object point hitting the lens at radius r for a marginal ray angle of \theta_1, the output ray will have angle \theta_2=\theta_1 - \arctan\frac{r}{f} as in my post above. If you assume n is everywhere unity, then NA=sin θ. For small angles, which is already the assumption, we have
:\theta_1 = \arctan\frac{r}{d} \approx \frac{r}{d}
:\theta_2 = \theta_1 - \arctan\frac{f}{d} \approx \frac{r}{d}-\frac{r}{f}
and so
:\sin\theta_1 \approx \frac{r}{d}
:\sin\theta_2 \approx \frac{r}{d}-\frac{r}{f}
and so, assuming n=1:
:\mathrm{NA_1} \approx \frac{r}{d}
:\mathrm{NA_2} \approx \frac{r}{d}-\frac{r}{f} = \mathrm{NA_1}-\frac{r}{f}.
This appears to be right from a few examples in ZEMAX. —Ben FrantzDale (talk) 16:13, 30 November 2011 (UTC)

thread_title:  Category for Kvens? 

message: I have studied and worked with the topic of this article for several years. 
It made me really worried when I read the article about "Kven people". 
Who is responsible for the articles content? It looks like a political statement from the leaders of the Norwegian organisation named "Norske kveners forbund".
There are several serious errors in the article. If this article reflects the objectivenes of the articles in Wikipedia then the encyclopedic value of Wikipedia becomes critically low. Unfortunately.
I hope we together can rewrite the article to a far more objective one.
Nordmand (talk) 16:52, 5 August 2011 (UTC)
replies: text: I concur with what you say, Nordmand. However, I do believe it is almost entirely accurate, and the innaccuracies (if any) are such that I can't discern them, given my somewhat limited knowledge about the subject. However, I would like to add that is happens that the Finnish dialect that is spoken in the Upper Peninsula of Michigan by most Finnish Americans (this being the area with the highest percentage of Finnish American immigrants and their descendants) is predominantly from the Torneo Valley of Sweden, and would hence be probably considered a Kven dialect. The reason for this is due to a couple of facts: 1) the earliest immigrant wave of Finnish people to Michigan's Upper Peninsula came to work the mines from the mining region of the Torneo Valley, and 2) these people were almost all from the Laestadius Sect of Lutheranism, which in America became the Old Apostolic Lutheran Church, and as such, they quite frankly breed like rabbits. So, later waves of immigrants from Finland proper (especially after the Finnish Civil War of 1918-1921) were outnumbered over the years by the hugely prolific Kven Finns - the distinction is made here between the Finns of that time as being either "Red Finns" or "Church Finns". Today, almost all Finnish Americans in Michigan (and in northern Wisconsin and Minnesota and Western Ontario) speak the Kven dialect. --Saukkomies talk  20:58, 23 September 2011 (UTC)

Currently Narcissistic Injury has no content to include, but as it seems a verifiable concept, it can redirect pending additional verifiable, referenced content. In the case of Celebrity Narcissism which is unverified and totally devoid of citation it cannot be similarly included or redirected.--Zeraeph 09:22, 13 October 2006 (UTC)

Talk:Road roller

message: The term roller-compactor appears to be a well-understood term within the construction industry, but it is also used within the pharmaceutical industry for some kind of manufacturing plant.  The need to differentiate between these is the reason for this article being called road roller, rather than roller-compactor (which is what it started life as - see first section on this talk page).
This site, chosen at random from Google, is a sales site for construction equipment, and contained a wide selection of items that I would call 'diesel rollers' (or 'road rollers', or just 'rollers') - all labelled as 'roller-compactors'.
Hence the terms appear to be interchangeable. -- EdJogg 18:15, 4 September 2006 (UTC)
