"Ear screen" may refer to a different meaning of "screen" - a device that protects you from something, as in "sun screen". In this case, the "ear screen" would block the sound of the phone's speakers, making it useless (at least for telephony). 08:02, 10 July 2015 (UTC)~~ [[User:thepike|thepike]]

Doesn't running natively just mean that it runs apps natively instead of emulating them or something. Which would be a pointless marketing term OR it implys that the phone itself or the person inside runs.[[Special:Contributions/108.162.249.192|108.162.249.192]] 10:53, 10 July 2015 (UTC)

Wireless discharge: I think the explanation is too complicate. Every cellphone (and every other device that uses batteries) does discharge without a wire, it is just normal. The joke (in my eyes) is here that no-one would advice with that. --[[User:DaB.|DaB.]] ([[User talk:DaB.|talk]]) 11:43, 10 July 2015 (UTC)

Here's an idea: a phone that discharges it's power wirelessly into another device.(unlikely that this is what it means though)[[Special:Contributions/108.162.249.166|108.162.249.166]] 12:39, 10 July 2015 (UTC)

I think most explanations of the the mirror issue overlook an even simpler explanation -- Things appear to be flipped such that left and right are reversed. However, that is only because you are used to things, such as people, rotating about a vertical axis, with top and bottom staying in the same position. If a clone of you stood on its head and you faced each other, your right arms would be on the same side (e.g. "closer to the door"). Now, if you look in a mirror, it is the same as seeing the clone flipped top to bottom. [[Special:Contributions/24.41.66.114|24.41.66.114]] 01:06, 6 September 2013 (UTC)

Of course with '''''vertical''''' mirror vertical axis is selected: perceived switching of left and right (really close with far to mirror surface). When '''standing on''' '''''horizontal''''' mirror we will perceive switching bottom from top. --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 09:09, 10 December 2012 (UTC)

You're certainly correct, but I think that the original question is not really asking about text (or other things) which are perpendicular to the mirror, but rather text which is parallel to it (and thus the close vs. far doesn't come into it). For example, when reading signs in your rear view mirror or holding a book in front of your chest while looking in a mirror. I've added a little bit to the explanation to attempt to help clarify what's happening in that situation. I'm not sure if it really helps or not. [[User:KeithyIrwin|KeithyIrwin]] ([[User talk:KeithyIrwin|talk]]) 10:00, 10 December 2012 (UTC)

Easier way to describe it: Imagine you hold a piece of glass. Write on the glass and hold it in front of the mirror, so that you can see both the original text and the mirrored text. Both versions of the text will look identical. So the mirror doesn't change anything. [[Special:Contributions/62.220.2.194|62.220.2.194]] 11:10, 10 December 2012 (UTC)

Another way: draw a line between the real object and its reflection. Things are reflected around that line. If that line is going up & down (relative to your eyes), then things are reflected left/right (relative to your eyes). If that line is horizontal (again relative to your eyes), then things are reflected top/bottom. So it's not so much whether the mirror is horizontal or vertical, but rather what direction you are looking into the mirror (although that can be influenced a lot by the mirror's orientation).[[User:CityZen|CityZen]] ([[User talk:CityZen|talk]]) 04:17, 11 December 2012 (UTC)

I always wonder: Since the sky goes from red to blue to red and the optical spectrum goes from red to green to blue. How come the sky is never green?
: Because of human color perception. You only perceive green in polychromatic light when said light is stronger in the middle wavelengths than the low or high wavelengths; in other words, you would need a process in the sky that removed ''both'' the high and low wavelengths from white light. As the sun sets, only the lower wavelengths are removed, so you perceive yellows and reds -- this perception of color is "one-sided", i.e. it is not interfered with by even longer wavelengths. By the way, sometimes you do see green briefly in the sky, it's called a [http://en.wikipedia.org/wiki/Green_flash Green Flash]. --[[User:Prooffreader|Prooffreader]] ([[User talk:Prooffreader|talk]]) 16:41, 10 December 2012 (UTC)
::I used to go outside after a rain storm during the day, and sometimes the sky would seem very green. The effect could last for hours. [[Special:Contributions/76.122.5.96|76.122.5.96]] 12:15, 12 December 2012 (UTC)
: The sky ''is'' green, at times. Growing up in the Upper Midwest (USA), I quickly learned that green sky means it's time to watch out for tornadoes. I don't know the actual connection between the two situations--I would guess from the previous comment that whatever atmospheric conditions create tornado conditions also "edit out" both high and low wavelengths, at least to a degree.

About [http://www.explainxkcd.com/wiki/index.php?title=1145:_Sky_Color&diff=22416&oldid=22414 this edition]: 1/(x^4) does not look like a root to me.

:You are correct. It's been fixed. The editor that made that edit was probably confusing 1/x4 with x1/4, the latter of which would indeed be the fourth root. [[User:Lcarsos|lcarsos]]_a ([[User talk:Lcarsos|talk]]) 19:53, 10 December 2012 (UTC)

[http://math.ucr.edu/home/baez/physics/General/BlueSky/blue_sky.html This page], linked from the explanation says that "the most strongly scattered indigo and violet wavelengths stimulate the red cones slightly as well as the blue, which is why these colours appear blue with an added red tinge." -- this seems rather strange. Assuming the cones are simulated based on frequency/wavelength, ultra-blue colors shouldn't stimulate the red cones because the electromagnetic spectrum is linear, not circular, despite the appearance of similarity between violet and red. Or am I missing something? --[[User:Waldir|Waldir]] ([[User talk:Waldir|talk]]) 16:14, 11 December 2012 (UTC)
: If you look at the response curve (middle of cited page) you'll see that red receptors have two peaks, one in the red wavelengths, and another (very tiny one) in the violet. That's why purple (which is red + blue) looks so similar to violet, and why the "color wheel" works. [[Special:Contributions/207.225.239.130|207.225.239.130]] 21:59, 11 December 2012 (UTC)
:: PS: "first years" is an idiom. Wouldn't that be "first year students" to be proper English? [[Special:Contributions/207.225.239.130|207.225.239.130]] 22:05, 11 December 2012 (UTC)
:::Idioms are "proper English" too. There is no doubt about what is meant here (or at least, I hope there isn't, but perhaps there are regional differences that mean some English speakers don't say "first years" to talk about students in their first year), and the register is not unduly colloquial for this kind of a site. 14:00, 12 December 2012 (UTC)
: The easiest way to explain mirrors is: they don't change left and right, they change forward and backward. What is farther from the mirror appears farther in the mirror. If you look at yourself, your nose and the nose of your reflection are the closest parts of the body together (at least in a bathroom mirror :-)), so *if there were* another person standing where the mirror *simulates* it, that person would wave it's right arm when you wave your left. But in a "absolute reference frame", both image and original wave their arm nearest to the door. Interestingly automobile drivers don't make this error: if you see a car in the rear mirror blinking left you don't assume they want to turn right...

There was a hilarious [http://en.wikipedia.org/wiki/Get_Fuzzy Get Fuzzy] strip where Rob tried to explain why the sky is blue to Satchel, but I can't find it. [http://homepage.smc.edu/morse_peter/phy14/LightOptics/GetFuzzyWhyIsTheSkyBlue.jpg This one?][[Special:Contributions/98.174.41.183|98.174.41.183]] 00:49, 31 December 2012 (UTC) Yes that's the one. --[[User:Smartin|Smartin]] ([[User talk:Smartin|talk]]) 04:23, 1 January 2013 (UTC)

: I would also just like to add that, as I understand it, the Sun puts out a lot more blue light than violet light, so it would make sense for blue to dominate. After green light, where the Sun's output peaks, the intensity of the light starts dropping dramatically. {{unsigned|71.104.183.59}}

By the end, it's really starting to sound like a text-based fantasy adventure game, or possibly a game of D&D. This adds an additional level of humour: using Google Maps to navigate around virtual worlds.

I particularly liked the "Go pi miles", and the "Careful" instructions in the Google Maps "Action" column on the right. ''--[[User:MisterSpike|MisterSpike]] ([[User talk:MisterSpike|talk]]) 18:58, 26 June 2013 (UTC)''

I'm not sure what is meant by the use of the term "Straw Man" instead of scarecrow or some other spooky or Halloween-themed equivalent. Perhaps it is a reference to the fallacy, but the fallacy is unassociated with "waking" unless maybe it's loosely related to the aggression that generally accompanies the attack of a straw man. {{unsigned ip|173.245.56.66}}

:"They also apparently woke the Straw Man."
I don't think there's more implied than that they lost time getting past, or detouring around, 'the Straw Man'. [[Special:Contributions/108.162.219.203|108.162.219.203]] 14:13, 25 December 2013 (UTC)
