| titletext = I like the idea of cartograms (distorted population maps), but I feel like in practice they often end up being the worst of both worlds-not great for showing geography OR counting people. And on top of that, they have all the problems of a chloro... chorophl... chloropet... map with areas colored in.

This is the sixth entry in the ongoing [[:Category:xkcd Phones|xkcd Phone series]], released the day after Apple announced their new iPhone X with facial recognition features.

===List of features===

; Front camera (centered for eye contact during video chat)

: Front camera is a common feature of smartphones. The camera lens is located on the same side of the phone's case as the main screen, therefore it is possible to capture the image of the user's face looking at the screen and display the interlocutor's face on the screen simultaneously, enabling video chat. However, as the camera is usually located above the screen, a user looking at the displayed image of the other person directs his or her eyes at the center of the screen and not at the camera's lens. This is very visible on the other end of the chat as if the person talking was looking down and not in the interlocutor's face which is an uncomfortable situation for most people. For this reason, professionals involved in movie or TV making like actors or reporters are trained to look straight into the camera's lens while talking which creates impression of looking straight at the viewer's face. During a video chat, however, looking into the lens of an above-screen camera does not allow one to see the interlocutor's face clearly because it is then in the peripheral field of vision.

: To solve this conundrum, Randall proposes locating the camera lens right in the middle of the screen. Therefore the user looking at the screen to see the other persons' face would be also looking at the lens, creating an impression of a straight look on the other end of the chat. This is absurd since the lens would then take place of some of the center pixels of the screen, not allowing to display the center part of the captured image of the other person's face (like eyes and/or lips) which is most important for nonverbal communication. Such location of the camera lens would also likely interfere with touch screen function. It will make other applications on the phone difficult to use, since virtually no user interface is designed to accommodate for a blind spot in the center.

; Full-width rear camera

:

; CDC partnership - phone automatically administers seasonal flu vaccine to cheek every year

: U.S. {{w|Centers for Disease Control and Prevention}} is a government agency tasked with addressing public health concerns such as infectious diseases, including seasonal flu. A common way of limiting spread of an infectious disease is {{w|Vaccine|vaccination}}, which most often involves administering a specially prepared medicine via an {{w|intramuscular injection}}. This features implies that the phone would automatically perform such an injection once a year, by shooting a needle out of a small aperture while the user is holding the phone to his or her cheek during a call.

; 12-function

: Most smartphones can be used for more than 12 different things.{{Citation needed}}

; Dishwasher safe

: Usually a feature of plastic containers or fancy dishes. Unlikely to appear on a smartphone, though potentially useful if you need to clean your screen.

; GPS transmitter

: Many smartphones have a receiver for the Global Positioning System, which allows a phone to compute its position based on signals from the constellation of GPS satellites. However, a device with a "GPS transmitter" would broadcast signals that would interfere with the GPS receivers of all devices nearby

; 3-G acceleration

: Usually, a phone is 3g compatible if it uses a certain standard for data transmission. However, 3-G acceleration implies the phone can accelerate at a rate or 3 times the acceleration of gravity, or approximately 30m/s^2.

; Portable, solar-heated
: Portability is pretty much the entire point of using a ''mobile'' phone, so advertising portability is rather pointless. Solar ''power'' charging could be a very useful feature on a phone, but solar ''heating'' usually applies to plumbing, where a water tank is heated by the sun and used to supply hot water to taps. Technically, as the sun heats up everything on Earth, the phone is in fact solar heated.

;Pore-cleaning strip

: Something sticky on that location would be very annoying for people trying to make a call with beards.

; Maximum strength

:

; Never needs sharpening

: Phones do not need to be sharpened in the first place.{{Citation needed}} This is a feature more likely to be used in a knife advertisement or apply to a mechanical pencil, which does have the advantage of never needing to be sharpened as opposed to a normal pencil.

; Can survive up to 30 minutes out of water

: This is a play on the common IP-rating of water resistance, which is typically rated for submersion to a rated depth for 30 minutes. A phone which could only be used or carried for 30 minutes and then needed to be immersed in water would be rather inconvenient.

; Exclusive Audubon Society app identifies birds and lets you control their flight

: {{w|National Audubon Society}} is a non-profit organization dedicated to conservation of nature, mainly of birds, also organizing open {{w|birdwatching}} events. An app that identifies bird species, for example from a photo of a bird made by the smartphone itself, would be cool. An app allowing you to control the bird's flight would be way cooler, but it is not possible at the current state of technology{{Citation needed}} - and it would fly in the face of the Audubon Society core activity. This is a reference to {{w|Unmanned_aerial_vehicle|drones}} (artificial "birds") which are often controlled by a smartphone app. This may also be a reference to xkcd 1425 Tasks, in which an app that can recognize if a bird is on camera is proposed.

; Extra screen

:Because of the center camera, an additional section of screen was added. This is similar to the new iPhone, which also has a few extra pixels up there.

; Wireless charging port

:Wireless charging has no wires, and needs no port.

; Safe for ages 6 – 8 months, 10 months, 18 months – 3 years, and 12 years and older

:Usually an item is deemed safe for a particular age or older, or (in the case of toys) is recommended for a particular age range. This is unusual in that it's a hodge-podge of age ranges with no apparent reason why some ages are safe and others are not.

; Screen goes past the edge

:An over-exaggerated version of the "edge to edge" displays in recent generations of smartphones

; High thread count CPU

:High thread count typically applies to bedding, not CPU threads.

; Shroud of Turin-style facial transfer unlock

:The {{w|Shroud of Turin}} is claimed to display an image of the face of {{w|Jesus Christ}}, appearing as if it was transferred to the cloth. Presumably, to unlock this phone, the user must press their face against it.

; Fonts developed by NASA

: NASA's expertise is not in fonts, and the fonts on almost all modern phones are the same.

; Includes applicator

:

; Burns clean coal

: There is a push for clean energy production as a result of increased awareness of global warming. While it may be useful for a phone to be able to produce its own energy, coal is by definition not a clean energy source because it produces carbon dioxide. The phone is not stated to have a vent for the CO2 to escape, which would technically make the coal "clean" as it is not entering the atmosphere. However, the gas is instead trapped inside the phone, which will quickly ruin it through a combination of heat and pressure.

; Pre-seasoned

:Pre-seasoned typically refers to cast iron cookware which is ready to use out of the box, as opposed to needing to season it with oil and heat. It can also refer to packaged meats which are ready to cook without needing to be seasoned with herbs and spices.

; Broad-spectrum SPF 30

:The xkcd phone somehow gives an SPF 30 level of skin protection from the sun.

; College-ruled

:College-ruled is a style of notebook paper having narrower lines in order to fit more text per page.

; Sterile packaging

:

; Radium backlight

The discovery of the phosphorescent element radium sparked a brief fad in which some watch makers painted watch faces or hands with the substance so the time could be read at night. However, it was eventually realized that regular exposure to radium could result in radiation poisoning, particularly for the workers assembling and painting the watches. A radium-based backlight would therefore be both potentially dangerous (especially for an object carried on one's person much of the time) but also largely useless, as the phosphorescence of radium is rather dim compared to conventional phone back lights.

; 4K pixels (50x80)

:This refers to having 4,000 pixels in the screen in total, rather than a screen width of ~4000 pixels. TV's advertised as "4K" are typically up to 4096 × 2160 pixels, or 8.8 million pixels. That would be outstanding for a cell phone whereas 4,000 pixels total would be horrendous. As a comparison, the old Commodore VIC-20 with a resolution of 176 x 184 would have over 8 times the pixels of this phone.

1877: Eclipse Science

Turmacar: /* Explanation */

{{comic

| titletext = I was thinking of observing stars to verify Einstein's theory of relativity again, but I gotta say, that thing is looking pretty solid at this point.
}}

==Explanation==
{{incomplete|Created by a BOT - Please change this comment when editing this page. Do NOT delete this tag too soon.}}
This comic reflects on various reasons scientists have for being interested in a total solar eclipse. As the reporter probes Megan on scientific interest on the eclipse Megan gives rather sarcastic answers, downplaying any experimental significance of the phenomenon. She makes a point that science is involved in many things, but it does not work to observe phenomenon without any interest in discovery. Eclipses are well known events and there is no lack of models for explaining the physics behind them. The whole event is only significant to the observer, the alignment of bodies in space is a result of orbital mechanics which are present at all times.

While some astronomers might be testing elaborate hypotheses during an eclipse, for other scientists (eg. organic chemists and herpetologists) it is just a once in a long time (maybe even once in a lifetime) event which is visually interesting.

Megan's point is that in 2017 (and for several decades/centuries previous) eclipses are thoroughly understood. Wikipedia has a listing of [[wikipedia:List_of_solar_eclipses_in_the_21st_century|every eclipse that will occur in the 21st Century]], to include the coordinates and time of greatest eclipse. While eclipses offer a unique opportunity for ground based observation of the Sun's outer layers the majority of the study of the sun is done by satellites that do not require an eclipse to take readings.

The alt text refers to a [[wikipedia:Tests_of_general_relativity#Deflection_of_light_by_the_Sun|1919 experiment during an eclipse]] to observe gravitational deflection of light waves.

==Transcript==
:Hairy [''holding a microphone'']: Tell us, are you scientists excited for the eclipse?
:Megan: Sure, lots of people are!

:Harry [''O.S.'']: Is this a big moment for science?
:Megan: It's a big moment for the sky.

:Harry: Are people really excited enough about science to travel to see it?
:Megan: Honestly, it's not that scientific. I mean, it's cool if you're into astronomy, but it's also cool if you're, like, aware of the sun.

:Harry: But there's lots of science involved.
:Megan: I guess? There's lots of science involved in the Olympics, but you don't need to be a scientist to watch.

:Megan: It's not like the concept is all that arcane of mathematical. It's a thing going in front of another thing.

:Harry [''O.S.'']: Then why are you so excited?
:Megan: I'm excited because it's a nearly once-in-a-lifetime chance to watch the sun go dark, hear birds freak out, and see a glowing ring appear in the sky with a sunset on every horizon.

:Harry: Will you be making any scientific observations?
:Megan: I will be, like, "Holy shit, look at the sky."
:Megan: Maybe also "This is so cool."
:Megan: We'll see!
