Where is the Cueball shouting "wheee!!"? [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 19:59, 16 August 2024 (UTC)

In the transcript I described how the cars are hanging, but I'm worried I've gone too far from transcript to explanation. Hopefully someone can improve it. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 20:02, 16 August 2024 (UTC)

There's no category for "X fired me because" comics. There probably should be. [[User:Barmar|Barmar]] ([[User talk:Barmar|talk]]) 20:06, 16 August 2024 (UTC)

== Just HOW fast? ==

I was vaguely surprised to see nobody had done the math yet. So here it goes -- someone more confident in editing the main entry can feel free to adapt this if you think it's interesting enough (I doubt anyone would want to read the math as I wrote it). But first, someone please check my work. :)

I opened the comic in a pixel-level photo editor, and took some quick measurements. The wheel on the left seems to be approximately 160 pixels wide, whiile the inner hub is about 14 pixels high.

So the gear ratio is 160:14 or about 11.04 Just for simplification, let's call it a 10x ratio.

The [https://en.wikipedia.org/wiki/Ferris_wheel#The_original_Ferris_Wheel original Ferris Wheel] took about 20 minutes to load and unload passengers, then ran for 9 uninterrupted minutes for another, full, rotation. So again, let's round up and say the wheel on the left takes about 10 minutes to go around once.

The middle wheel, then, would take a minute. And the last one, a tenth of a minute, or 6 seconds.

The original wheel (again) was about 265 feet across, or a circumference of 832 feet. So if these wheels are the same size (why not?), any car on the right-most wheel would move about 832 feet in 6 seconds, or 138 feet per second, which is about 94 miles per hour (151 kilometers per hour).

I can see why he was fired.

Taking the reverse: The rightmost wheel would take about 10 minutes for a rotation, the middle wheel, 100 minutes (1:40), and the left most, 1000 minutes (16 hours and 40 minutes).

Actually, if you move slow enough that the right wheel can load and unload (let's say 20 minutes, just like the original wheel), it'd take over a day to load the left wheel.

This Amusement Ride manufacturer has a helpful diagram of rotational speed on their website: https://www.sinorides.com/everything-you-need-to-know-about-ferris-wheels/#q11
The example wheel happens to have 18 gondolas, just like Randall's and appears to be roughly the same scale. The sample values they provide are a linear speed of 4 m/s at the edge of the wheel and a rotational speed of just under 3 revolutions per minute. My best guess at the gearing ratio of Randall's belt driven wheels is 10:1, so if the left wheel is being driven at normal speeds, the center wheel would be 40 m/s or 30 rpm and the left wheel would be 400 m/s or 300 rpm. This exceeds the square root of the specific strength of standard steel, so we'll need to hope that the right most Ferris wheel is made of a particularly strong alloy.

: Ah, well, I started down my own road for calculations, based upon the assumption that they were 75 feet diameter (from the height of the figures, assuming that the ones I actually checked definitively up to 6ft, give or take, although pixel-counts upon antialiased graphics can be quite inaccurate the fewer 'apparent' pixels there are). As a truck-portable/mounted fairground-style ride, it's probably quite a bit smaller than the 'original Ferris wheel' and many of those 'permanent' wheels (London Eye, theme park rides, etc) that are built specifically to be architectual 'statements'/tourist-magnets. I'm thinking more the kind that you'd see in Grease (though that one's 55-foot, apparently) or the one that 'Night Monkey' had to deal with in Spiderman: Far From Home. I also looked up [https://www.giantwheel.co.uk/35m-vision-ferris-wheel-hire/ actual specs] (that's 35m, ~105ft, and 0.5rpm, so not too far off my initial assumptions). There also was a rather larger 60-metre (197 ft) {{w|Wheel of Sheffield|semi-permanent}} transportable version with 13 minute continuous 'ride', but that'd be completely out of scale to those depicted.
: If there are any actual 'carnies' out there who know what kind of thing actually gets used at County Fairs in the US, that might help. (Here in the UK there's currently a Fun Fair about a quarter of a mile from my house, at the moment - though I'm not there at the moment, but they have no 'big wheels' of that kind, only the more energetic types that ''do'' fling their riders around, like the "Terrifying Claw" and various other heavy duty hanging and/or spinning-seat rides.) ((Slightly ninjaed, now, by the above contribution.))) [[Special:Contributions/162.158.33.197|162.158.33.197]] 21:37, 16 August 2024 (UTC)

I can't help but think of this as Randall wanting to make an upscaled version of [https://www.youtube.com/watch?v=QrkiJZKJfpY Steve Mould's Spintronics video] from a year ago... [[Special:Contributions/172.68.50.126|172.68.50.126]] 21:54, 16 August 2024 (UTC)

Given that air resistance increases exponentially with air speed, this setup would actually act as its own speed regulator, with the main factor being the torque of the power source. Which wheel is powered would not matter much [[Special:Contributions/172.71.118.167|172.71.118.167]] 22:05, 16 August 2024 (UTC)

If you powered the middle one, you'd end up with one moderately exciting ride, one normal ride, and one really long ride, which would be highly impractical, but not overly dangerous (depending on the structural strength of the fast wheel).

== Are the transcript eds going to go into the speeds depicted? ==

Should the transcript involve the diameter ratios when explaining the speed depiction gray lines? [[Special:Contributions/172.70.211.83|172.70.211.83]] 23:06, 16 August 2024 (UTC)

1572: xkcd Survey

2022-11-05T04:52:25Z

172.71.142.88: update to time

{{comic
| number = 1572
| date = September 2, 2015
| title = xkcd Survey
| image = xkcd_survey.png
| titletext = The xkcd Survey: Big Data for a Big Planet
}}
*The original comic links to [http://goo.gl/forms/B5RaBeZ6nw The xkcd survey] at Google, which is closed now.

==Explanation==
As the comic image states, it links to a survey created with [https://www.google.com/forms/about/ Google Forms], containing a series of questions. The questions range from mundane typical survey questions such as “Do you have any food allergies?”, to rather strange, such as “Fill this text box with random letters by randomly mashing keys on your leopard.” (See [[1530: Keyboard Mash]] and [[1031: s/keyboard/leopard/]]).

The stated goal of the survey is to “create an interesting and unusual data set for people to play with”. A strange data set is a ripe opportunity for a sampling of readers. It's also supposed to be “a search for weird correlations” – presumably the goal is to be able to say things like “people who have been skydiving are (more/less) likely than average to dislike cilantro”. (See also [[882: Significant]] about finding presumably-spurious correlations between unrelated data.)

If the data is ever released, this explanation will be updated, but as of November 2022, this has not happened.

{{w|Image_map#Client-side_image_map|HTML image maps}} is a technique for marking up areas of an image on a web page, such that each area can be a link without the whole image being a link. [[Randall]] could have used this type of image map to make only the “Click here to take the survey” button be a link, and none of the rest of the image. But he cannot get the hang of it (or knowing his skills, does not wish to take the time to learn it). Not getting the hang of HTML image maps was also referenced on the banner for his [[xkcd_Header_text#2014-07-23_-_what_if.3F_book_tour|book tour]] for the [[what if?]] book. See the link for other instances where he mentions this problem in the [[xkcd Header text]].

The title text is a joke off of {{w|Big Data}}, which is a name for analysis of a set of data that includes a huge amount of information. He also says "for a big planet" because the Earth is big.{{Citation needed}}

The survey is closed, and the questions replaced with the text: "The xkcd survey is now closed. Thank you for all your answers! Response data is being collected and will be posted soon." As of August 2022, the same caption is still there, with no indication of exactly how soon the data is intended to be posted. (Apparently, Randall crashed google forms, so the data is taking a long time to be retrieved [https://www.reddit.com/r/xkcd/comments/40mhve/what_ever_happened_to_the_survey_we_took/ (see this reddit thread)] - much like his breaking of [http://what-if.xkcd.com/imgs/a/62/balloon_wolfram.png Wolfram Alpha]] during answering a reader's question on [[what if?]])

==The Survey==
A recreation of the survey can be found [https://goo.gl/forms/CtAILwjyJAYsmqbO2 here on Google].

The recreation's data can be [https://goo.gl/5A77ZX found live here.]

It started with the following statement:

<nowiki>This is an anonymous survey. After it's done, a database of everyone's responses will be posted.
There's no specific reason for any of the questions. The goal is to create an interesting and unusual data set for people to play with. This is obviously not going to be a real random sample of people, but in the interest of getting cooler data, if you're sharing this with friends, try sending it to some people who wouldn't normally see this kind of thing!

WARNING: This survey is anonymous, but your answers WILL BE MADE PUBLIC. Depending what you write, it's possible that someone may be able to identify you by looking at your responses. None of these questions should ask about anything too private, but don't write anything that you don't want people to see. If you're not comfortable answering a question, just skip it.</nowiki>

; Aluminum foil
Why would aluminum foil be valuable? I can see how it would be hard to produce at the time. But how would it be used and why would people of the time see a lot of value in it? [[Special:Contributions/172.71.146.65|172.71.146.65]] 03:42, 5 November 2022 (UTC)
:Good question, but I'm persuaded the novelty and scarcity of metallic aluminium would have made it plenty valuable among those already wealthy enough to recognize what it was. Prussia was wealthy and Königsberg was its largest port city back then, so probably the mayor would have been able.

::Aluminium was very valuable - methods for its extraction from ore didn't exist in any useful form until much later. [[Special:Contributions/172.68.146.80|172.68.146.80]] 03:55, 5 November 2022 (UTC)
::: But what makes it valuable? Is it just the scarcity? Since nobody had this material back then, there wouldn't be any known applications for it. Compared to bringing e.g. a simple pocket calculator, a flashlight, a solar-powered e-book reader, etc. [[Special:Contributions/172.71.142.88|172.71.142.88]] 04:05, 5 November 2022 (UTC)
