A little bit more of 730? [[Special:Contributions/141.101.80.108|141.101.80.108]] 06:53, 18 February 2015 (UTC)
:More along the lines of 94, 210, 518, 627, 844, 845, and 1195, though I see similarities with 730. [[User:Mikemk|Mikemk]] ([[User talk:Mikemk|talk]]) 07:09, 18 February 2015 (UTC)
How should we do the transcript? [[User:Mikemk|Mikemk]] ([[User talk:Mikemk|talk]]) 07:09, 18 February 2015 (UTC)

You could do the transcript as a number list formatted like: "[Title of item] IF YES(GOTO X), IF NO(GOTO Y)" (where "X" and "Y" are the numbers on the list for the corresponding next option). Derek [[Special:Contributions/108.162.216.107|108.162.216.107]] 13:25, 18 February 2015 (UTC)

I would just like to say that I find some of the linked spiral-images ''very'' disturbing. Although for some they'd be the same even ''without'' the spirals, admitedly. [[Special:Contributions/141.101.98.188|141.101.98.188]] 09:47, 18 February 2015 (UTC)

I believe this will end up being one of the most challenging explanations yet (of those that are completely explicable) - got quite a task up ahead... -- [[User:Brettpeirce|Brettpeirce]] ([[User talk:Brettpeirce|talk]]) 10:35, 18 February 2015 (UTC)

Normally (for a flowchart) the Start symbol should not have an input. The electrical circuit is not a rectifier! Sebastian --[[Special:Contributions/108.162.254.103|108.162.254.103]] 10:59, 18 February 2015 (UTC) In the newly corrected version, it is. [[User:Knob creek|Knob creek]] ([[User talk:Knob creek|talk]]) 16:58, 18 February 2015 (UTC)

OCD comment: There appear to be two lines missing, 1) from scatter plots to data or axis, 2) from the bottom of positive or negative DC terminal to the negative terminal of the battery. Also, I would be happier if the two left hand diodes of the full wave rectifier were reversed.

Either I was really tired this morning, or the spiral was not actually present in the first version of this comic.[[Special:Contributions/108.162.254.98|108.162.254.98]] 13:00, 18 February 2015 (UTC)

It seems like the options for the "Do you like flowcharts?" box should be reversed (only putting someone through the flowchart if they say they like flowcharts). I think it makes less sense to have the first option "annoy" someone with a flowchart option until they say they don't like flowcharts, then put them through a flowchart. Derek [[Special:Contributions/108.162.216.107|108.162.216.107]] 13:31, 18 February 2015 (UTC)

I see no evidence that the "time or your happiness" box is asking you to "choose whichever you value more". The graph shows your happiness as a function of time, not "your time" (it's not as if you were asked to choose between, say, more happiness or more spare time for yourself). I think it is just asking you to choose which axis of the graph you want to follow. The flowchart for the line graph and the scatter plot are similar; since "X or Y" is not interpreted as a question about value, why should "time or your happiness" be?
Zetfr 14:00, 18 February 2015 (UTC)

The comment on the Fibonacci and Golden Spirals being the same is not correct. According to Wikipedia{{w|Golden_Spiral|[1]}}{{w|Fibonacci_number|[2]}}: "A Fibonacci spiral '''approximates''' the golden spiral using quarter-circle arcs inscribed in squares of integer Fibonacci-number side." - [[User:Prometheusmmiv|Prometheusmmiv]] ([[User talk:Prometheusmmiv|talk]]) 14:55, 18 February 2015 (UTC)

Randall has uploaded a new version, it fixes some missing lines: The scatter graph is now connected, as is the DC terminal, and the battery is now in a circuit. Some of the explaination above needs updating [[Special:Contributions/141.101.99.47|141.101.99.47]] 15:32, 18 February 2015 (UTC)

This comic is a flowchart style. Interestingly, the first option, "Do you like flowcharts?" loops back to itself until you choose NO. This is probably because the reader will keep choosing "yes" until they are annoyed and do not like flowcharts anymore.

After asking about flowcharts, the reader is asked whether they like line graphs. If they follow one line, it becomes a line graph where "Time" is the x-axis and "Your Happiness" is the y-axis, and shows that your happiness increases with time. If they follow the other line, they are asked "Charge a battery?" If the follow one line (probably "yes" but it's not marked) they are asked whether they are A/C or D/C (the only choice is A/C) and are led to a portion of the flowchart which roughly resembles a circuit diagram of a rectifier bridge (but the diodes are in a circle, not pointing towards the positive or negative terminal) with a battery connected to it.

If the reader follows the "no" line, they are asked if they like spirals. If they choose "no" they are told to take the path of least resistance. This part of the flowchart resembles a circuit diagram, and the word "resistance" is a pun because resistance in electricity is an electrical quantity that measures how the device or material reduces the electric current flow through it. Thus, whether they choose "Yes" or "No", they arrive at "Do you like when people find the golden spiral in random images?" If they choose "yes" the line fades into a drawing of a golden spiral, and we see that the flowchart is structured around it. If they choose "no" they are asked if they are tired of flowcharts. If not, they are taken to the beginning to start over again. If they are tired, the line points to the "random" button on the xkcd website.

The title text and the faint image of a golden spiral parody the fact that the golden spiral is superimposed on nearly ''everything''. The golden spiral is a spiral that has the growth rate of the golden ratio, a number that has inspired both artists and mathematicians alike. However, people try to find the golden ratio in seemingly random objects, and they fall to confirmation bias when drawing a golden spiral on top that seemingly fits. The comic links to [http://xkcd.com/spiral/], where one can see exactly that- golden spirals Randall "found" in random photographs. The title text is funny because the mathematics of the famous Fibonacci sequence and the golden ratio are actually one and the same- the limit of the ratios of each successive term in the sequence is equal to the golden ratio. So it matches up perfectly, not "almost" perfectly like the pictures in the mobile site link.

Talk:1474: Screws

2015-01-16T09:31:48Z

Knob creek:

This page is now on the first page of google for "uranium screw". [[User:Mrmakeit|Mrmakeit]] ([[User talk:Mrmakeit|talk]]) 05:31, 16 January 2015 (UTC)

I don't think that patent is the right one, it seems to describe a uranium decontamination procedure, not a screw made of uranium like in the comic. [[User:LeoDeQuirm|LeoDeQuirm]] ([[User talk:LeoDeQuirm|talk]]) 05:46, 16 January 2015 (UTC)

I'm pretty sure the "uranium screw" is just a reference to the fact that the head of the screw appears to have split in two ("fissioned"), as opposed to a normal flat head screw that still has the edges connected. [[User:Sam887|Sam887]] ([[User talk:Sam887|talk]]) 05:50, 16 January 2015 (UTC)

Just a shot in the dark here, but a company that sells uranium ore and radiological equipment happens to also sell screws for one of its Geigers that look just like the screw cross-section in the comic. [http://www.uraniumrocks.com/products/replacement-circuit-board-mount-screws-for-victoreen-cdv-700-short] [[User:Conqu2|Conqu2]] ([[User talk:Conqu2|talk]]) 06:01, 16 January 2015 (UTC)

I was wondering if the "uranium screw" was referring to the Demon Core -- two hemispherical domes that Louis Slotin was holding apart with a screwdriver. Then I remembered the Demon Core was plutonium, not uranium. [[Special:Contributions/173.245.48.119|173.245.48.119]] 06:49, 16 January 2015 (UTC)

There are ferrous alloys containing (depleted, of course ;-) uranium for "increase[d] toughness and strength". [http://en.wikipedia.org/wiki/Ferrouranium] [[User:Knob creek|Knob creek]] ([[User talk:Knob creek|talk]]) 09:21, 16 January 2015 (UTC)

I think the be was going for apple's pentalobe screw with the 5 ponted star

I don't think the uranium screws are named for their use in stuff to do with uranium, as I have both seen and used screws that look like that before. It's basically a flat head screw whose divot extends all the way across the face of the screw. I agree more with the previous commentor who notes that the screw looks like it has fissioned. [[Special:Contributions/108.162.237.182|108.162.237.182]] 06:34, 16 January 2015 (UTC)

An actual rivet is neither a screw nor a bolt; it's a fastener that is placed and then has one end plastically deformed -- traditionally by a rivet gun, but more often in smaller sizes by some sort of press or clamp. (Pop rivets are hollow, and are deformed by pulling a cone-sheaped wedge into the open end of the hollow core.) There's no way to remove one except to destroy it (drill it out or cut one end off). The item pictured could also be the head of a carriage bolt, but that's no help if you can't get at the other end of the bolt. Randall is slightly pessemistic, though: there *are* some "security" screws and bolts that use a slightly-elliptical domed head that's hard to tell from a rivet; they can be unscrewed, but only with a matching slightly-elliptical socket. [[Special:Contributions/199.27.133.70|199.27.133.70]] 06:35, 16 January 2015 (UTC)

All of which can be removed by a sonic screwdriver. Totally a real thing.

Could the "cursed -1" be a Nethack reference? I don't know if Dungeons and Dragons has the "blessed/uncursed/cursed" status, but in Nethack cursed items with negative enchantments (denoted "cursed -whatever") are a pretty common occurrence. [[Special:Contributions/199.27.133.25|199.27.133.25]] 07:31, 16 January 2015 (UTC)

In Nethack, Cursed objects cannot be removed. Seems appropriate. At first I thought it was a pozidrive screw head. Posts on the fission screw head: where have you seen screws whose divot does *not* extend across the head?

[[User:Kreuiter|Kreuiter]] ([[User talk:Kreuiter|talk]]) 08:03, 16 January 2015 (UTC)from wikipedia: Louis Philippe Joseph d'Orléans (13 April 1747 – 6 November 1793) commonly known as Philippe, was a member of a cadet branch of the House of Bourbon, the ruling dynasty of France. He actively supported the French Revolution and adopted the name Philippe Égalité, but was nonetheless guillotined during the Reign of Terror

I don't think it is specifically a reference to Nethack as a lot of ol games (both video and tabletop) use the mechanic of non removable cursed objects. It is common enough in my opinion that we could argue about until we are blue in the face and get nowhere.

--[[Special:Contributions/108.162.216.59|108.162.216.59]] 08:28, 16 January 2015 (UTC)
uranium screw may be a reference to [http://en.wikipedia.org/wiki/Louis_Slotin#Criticality_accident Louis Slotin], who died when he was using a screw driver to seperate two halves of a plutonium sphere as part of a science demonstration, and triggered a large burst of radiation when his hand slipped.

I'm thinking it might benefit the article to include a place in the wikitable for the correct term for each drive socket. Of course their are not correct terms for each of them. Not to mention rivets and Phillip's heads don't even have drive sockets. [[Special:Contributions/173.245.56.189|173.245.56.189]] 09:04, 16 January 2015 (UTC)BLuDgeons

If you suggest cursed-1 is because if misuse - I in first place thought of [http://en.wikipedia.org/wiki/List_of_screw_drives#Pozidriv] as the cursed one - because Philipps and Pozidriv are slightly incompatible and causes damage. [[Special:Contributions/108.162.254.18|108.162.254.18]] 09:09, 16 January 2015 (UTC)

Is it really true that Phillips head are 'commonly used in construction'? At least in Europe they were replaced by Pozidriv in the 1990's and these days by Torx.

Maybe this depends on the quality of the product? If i look around, i find lots of products held together by phillips screws and only a few (usually more hi-tech and expensive) one with torx screws. [[User:Knob creek|Knob creek]] ([[User talk:Knob creek|talk]]) 09:28, 16 January 2015 (UTC)

All of which can be removed by a sonic screwdriver. Totally a real thing.

Could the "cursed -1" be a Nethack reference? I don't know if Dungeons and Dragons has the "blessed/uncursed/cursed" status, but in Nethack cursed items with negative enchantments (denoted "cursed -whatever") are a pretty common occurrence.

In Nethack, Cursed objects cannot be removed. Seems appropriate. At first I thought it was a pozidrive screw head. Posts on the fission screw head: where have you seen screws whose divot does *not* extend across the head?

[[User:Kreuiter|Kreuiter]] ([[User talk:Kreuiter|talk]]) 08:03, 16 January 2015 (UTC)from wikipedia: Louis Philippe Joseph d'Orléans (13 April 1747 – 6 November 1793) commonly known as Philippe, was a member of a cadet branch of the House of Bourbon, the ruling dynasty of France. He actively supported the French Revolution and adopted the name Philippe Égalité, but was nonetheless guillotined during the Reign of Terror

I don't think it is specifically a reference to Nethack as a lot of ol games (both video and tabletop) use the mechanic of non removable cursed objects. It is common enough in my opinion that we could argue about until we are blue in the face and get nowhere.

uranium screw may be a reference to [http://en.wikipedia.org/wiki/Louis_Slotin#Criticality_accident Louis Slotin], who died when he was using a screw driver to seperate two halves of a plutonium sphere as part of a science demonstration, and triggered a large burst of radiation when his hand slipped.

I'm thinking it might benefit the article to include a place in the wikitable for the correct term for each drive socket. Of course their are not correct terms for each of them. Not to mention rivets and Phillip's heads don't even have drive sockets. [[Special:Contributions/173.245.56.189|173.245.56.189]] 09:04, 16 January 2015 (UTC)BLuDgeons

If you suggest cursed-1 is because if misuse - I in first place thought of [http://en.wikipedia.org/wiki/List_of_screw_drives#Pozidriv] as the cursed one - because Philipps and Pozidriv are slightly incompatible and causes damage.

Is it really true that Phillips head are 'commonly used in construction'? At least in Europe they were replaced by Pozidriv in the 1990's and these days by Torx.

Maybe this depends on the quality of the product? If i look around, i find lots of products held together by phillips screws and only a few (usually more hi-tech and expensive) one with torx screws. [[User:Knob creek|Knob creek]] ([[User talk:Knob creek|talk]]) 09:28, 16 January 2015 (UTC)

This page is now on the first page of google for "uranium screw". [[User:Mrmakeit|Mrmakeit]] ([[User talk:Mrmakeit|talk]]) 05:31, 16 January 2015 (UTC)

I don't think that patent is the right one, it seems to describe a uranium decontamination procedure, not a screw made of uranium like in the comic. [[User:LeoDeQuirm|LeoDeQuirm]] ([[User talk:LeoDeQuirm|talk]]) 05:46, 16 January 2015 (UTC)

I'm pretty sure the "uranium screw" is just a reference to the fact that the head of the screw appears to have split in two ("fissioned"), as opposed to a normal flat head screw that still has the edges connected. [[User:Sam887|Sam887]] ([[User talk:Sam887|talk]]) 05:50, 16 January 2015 (UTC)

There are ferrous alloys containing (depleted, of course ;-) uranium for "increase[d] toughness and strength". Cf. http://en.wikipedia.org/wiki/Ferrouranium. [[User:Knob creek|Knob creek]] ([[User talk:Knob creek|talk]]) 09:21, 16 January 2015 (UTC)

Just a shot in the dark here, but a company that sells uranium ore and radiological equipment happens to also sell screws for one of its Geigers that look just like the screw cross-section in the comic.

I was wondering if the "uranium screw" was referring to the Demon Core -- two hemispherical domes that Louis Slotin was holding apart with a screwdriver. Then I remembered the Demon Core was plutonium, not uranium. [[Special:Contributions/173.245.48.119|173.245.48.119]] 06:49, 16 January 2015 (UTC)

I think the be was going for apple's pentalobe screw with the 5 ponted star

I don't think the uranium screws are named for their use in stuff to do with uranium, as I have both seen and used screws that look like that before. It's basically a flat head screw whose divot extends all the way across the face of the screw. I agree more with the previous commentor who notes that the screw looks like it has fissioned.

An actual rivet is neither a screw nor a bolt; it's a fastener that is placed and then has one end plastically deformed -- traditionally by a rivet gun, but more often in smaller sizes by some sort of press or clamp. (Pop rivets are hollow, and are deformed by pulling a cone-sheaped wedge into the open end of the hollow core.) There's no way to remove one except to destroy it (drill it out or cut one end off). The item pictured could also be the head of a carriage bolt, but that's no help if you can't get at the other end of the bolt. Randall is slightly pessemistic, though: there *are* some "security" screws and bolts that use a slightly-elliptical domed head that's hard to tell from a rivet; they can be unscrewed, but only with a matching slightly-elliptical socket.
