message: I think some people have the idea that a mirage is a hallucination. When they're in the desert dehydrating they see an Oasis that really isn't even there...............and dive right into sand. But, that's not what it is. Should this be added to avoid confusion?

message: While closely related, and they certainly should be linked, I see two seperate articles on Mirage and Highway mirage as making sense.  I grew up seeing a lot of highway mirages in the Oregon desert.

replies: text: Yes, there is absolutely no reason to have a separate article on "highway mirages". It is exactly the same phenomenon as a desert mirage. The only difference is that it happens to occur on a highway. --Srleffler 12:03, 26 May 2006 (UTC)
thread_title: Highway Mirage

message: Srleffler, you changed the normal adiabatic gradient from +1 to -1°/100m. Although more correct, now the statement: smaller than -1° is confusing. Mathematically speaking -1.1 is a valid solution, but intuitively speaking people will think of -0.9 etc. (In fact the latter is meant). Please think about some rewording.
Likewise ±3 is mathematically speaking +3 or -3 (as the solution of the square root of 9). ~3 for 'circa 3' would be better, as was intended. But maybe less known. Some rewording? 
Oh, and thanks for general cleaning up my English --Tauʻolunga 20:02, 26 May 2006 (UTC)
replies: text: I see. However the values quoted were for an inferior (-) image only. Values for the superior (+) image were not given. But I reckon that we can keep it like this until someone comes with additional data. --Tauʻolunga 00:56, 31 May 2006 (UTC)

message: Mirage is called "Mareechika" in Sanskrit (Ancient Indian) language.  
Can someone tell me whether there is any relationship between these two?
If thats true, it might have originated from Indo-Aryan word rather than from something like 'Mirror' !—The preceding unsigned comment was added by Shreeshiri (talk • contribs) .
:The SOED and Chamber's Dictionary of Etymology agree that it comes from the French mirage, from mirare "to look at, to wonder at", from the Latin mirare "wonder at". It's related to the Sanskrit smayas "surprise, astonishment", but not to mareechika as far as I know. —Keenan Pepper 23:21, 16 June 2006 (UTC)
replies: text:  "mirage" is the French substantive of the verb "mirer" which means "to reflect" (for a mirror) or "to look at one's reflection in a mirror" (for a person). It does indeed eventually come from "mirare" in Latin, but the meaning in French applies exclusively to mirrors and reflecting surfaces. The French equivalent of "mirare" is "admirer" (to admire) which also comes from Latin "ad+mirare". 93.132.243.66 (talk) 21:21, 23 September 2011 (UTC)
replies: text:  PS: Even the pronunciation in English of the word "mirage" is copied directly from its French equivalent. Contrast this with the words "age", "cage", "forage", etc... which all come from French but have taken over time the typical English pronunciation of the vowel "a". It confirms, if need be, that "mirage" arrived into English directly from French. In turn, the French word comes from Latin. I do not however know the pre-Latin etymology of "mirare". 93.132.243.66 (talk) 21:30, 23 September 2011 (UTC)
thread_title:  Word Origin 

message: The article seems to have become a dumping ground for every image of a mirage there is, and there are too many images of mirages.  I've put most of the additional images into galleries at the end of the article, but eventually most of them should be removed and the most clear, understandable images remain.  -- atropos235 ✄ (blah blah, my past) 03:24, 7 June 2007 (UTC)
replies: text: Yes, these images should be moved to http://commons.wikimedia.org/wiki/Mirage and removed from this page. The article needs 2 or 3 images of mirages at most, not 50. Kaldari (talk) 00:18, 12 March 2008 (UTC)
replies: text: It would cut down on the inferior mirage images to remove the ones that aren't inferior mirages at all.  The three that look over water are superior mirages, and may as well be the first to be removed because they are mislabeled.  Remember - hot surface = inferior, cold surface = superior - as far as mirages are concerned.  See  for an example of an inferior mirage.  If there are no objections, I'll remove the mislabeled images from the gallery. Ikluft (talk) 13:19, 3 April 2008 (UTC)
thread_title:  TMI - Too many images 

message: Cold air is denser than warm air, and has therefore a greater refractive index.
Material density is not the same thing as optical density. This is non sequitur. The refractive index of a medium does not depend on its material density, as in its mass divided by its volume. Moreover, more dense media do not necessarily have a greater refractive index than less dense media.
If the passage means that cold air is more optically dense than warm air, it must explain why, since there is no obvious reason.

thread_title:  This article is predicated on a falsity. 

message: Can someone explain why the article states that mirages are not optical illusions? There appears to be water on the road; it's not actually there. That's an illusion, and it's due to an optical effect. Hence, optical illusion. It's not a cognitive optical illusion (that is, an effect created by the brain), but that doesn't mean it's not an optical illusion. Benizi (talk) 20:50, 4 February 2008 (UTC)
replies: text: Based on the optical illusion page, I modified the page to describe a mirage as a "literal optical illusion."66.253.237.191 (talk) 07:43, 14 May 2008 (UTC)

text: Mirages are NOT optical illusions. Optical illusions occur when the brain's visual processing sees an object as something that it is not, and will not fool a computer. Mirages, on the other hand, are seen because the light rays are actually being bent far in the distance. They are both captured on camera (as the article was mistaken about) and seen by the eye not because of peculiarities in the brain, but because of index of refraction changes in the distance. If you consider a mirage an optical illusion, you must also consider you looking in the mirror an optical illusion, and neither of them are. 18.250.0.182 (talk) 03:22, 19 June 2008 (UTC)

message: heat haze redirects here, but there's no mention of heat hazes on this page and as I understand they are a different phenomenon, involving a shimmering effect due to local variations in air density, rather than inversion.--Maltelauridsbrigge (talk) 15:51, 17 October 2008 (UTC)

message: Unfortunately on Wikipedia we have to balance viewpoints. The section "Supirior mirage" asserts that the earth is round and that is unfortunatly contested by a notable contingent of people. There is a difference between the SPOV and the WP:NPOV, Wikipedia is not Rational Wiki and we have to balance other veiwpoints, even if they are not widly considered correct.--Ipatrol (talk) 01:26, 29 January 2009 (UTC)
thread_title:  Don't feed the crazy wikis 

message: In the subtitle 'Cause', the last line of first paragraph says "The diagram on the left shows a light ray coming from the sky toward the hot ground. If the air near the ground is warmer than that higher up, the light ray bends in a concave, upward trajectory." But there is no diagram provided.
A diagram will really help to get a better understanding of the description provided. In the case of unavaliability of the diagram kindly edit the paragram. 
However I will recommend to provide a diagram on the right hand side of the passage and modify passage accordingly.

thread_title:  BBC report of superior mirage in 2021 

message: This article seems to have passed through a sizable convention of pedantic hands without anyone bothering to first adequately define the phenomenon of a mirage in clear, lay terms—the piece dives headfirst into endless layers of pedanticism.
The otherwise impressive illustrations make absolutely no sense if one is tasked with an a priori assumption of what constitutes a mirage in the first place. 
I’ll work on fixing it, but to the salient authors involved out there, please keep in mind that Wikipedia can only serve as an effective educational resource if the articles remain accessible first and foremost to those with no prior knowledge of the topics they are seeking. Crafting an article that goes straight into differential equations while omitting fundamental arithmetic suggests the author is more interested in officiousness and intellectual ostentation than they are in educating others selflessly.
