There is no rope in black hole analogy. On the other hand ... maybe one day this becomes common analogy for explaining some method of [http://en.wikipedia.org/wiki/Faster-than-light FTL] travel ... -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 08:52, 9 January 2013 (UTC)

<strike>It is no rope - it is a rubber sheet seen from the side. Sebastian --[[Special:Contributions/178.26.121.97|178.26.121.97]] 14:01, 9 January 2013 (UTC)</strike>sorry, you meant the rope there ;-) Sebastian --[[Special:Contributions/178.26.121.97|178.26.121.97]] 20:18, 9 January 2013 (UTC)

Did you see the harmonics of the wave? I think there are four different ones in the third frame. Sebastian --[[Special:Contributions/178.26.121.97|178.26.121.97]] 14:01, 9 January 2013 (UTC)

- Two harmonics, two different phases of each. [[Special:Contributions/123.237.156.13|123.237.156.13]] 15:56, 9 January 2013 (UTC)

- Realistically, the forms of the rubber sheet in panels 1-3 and possibly the last are significant. The first and second panels are probably illustrating something interesting related to Catenary curves and behaviour when external force is applied, the 3rd references wave reinforcement, the heavy ball is correctly moving straight up and down as expected under Newton's laws. I don't know if the orientation of the bowling ball, hight relative to how far down it is pulled or the vibrations have formal significance, but a physicist would be wise not to neglect them if they wanted to model the situation properly. The comic overall is clearly showing how a large number of well known effects can occur in a simple thought experiment. The tag line isn't joking when it says there is a lot of physics going on, those shapes aren't being chosen arbitrarily to look good. They are accurate illustrations of the situation being described. A look into the details of what a physicist might imagine, if you will.

It seems to me there should be a cross-reference to [[895: Teaching Physics]] (and if I knew more about the conventions of this wiki I would be bold and add it myself... but I don't, so I won't.) --[[Special:Contributions/67.36.177.100|67.36.177.100]] 17:35, 9 January 2013 (UTC)

: Furthermore, you could see the "BOOOIING" in this comic as an alternative to the "Boooooring" (only one-letter difference) at the end of [[895: Teaching Physics]] : Instead of becoming boring after "...Annnnd..." cliffhanger, the demonstration becomes really fun. Anyone to add that point in the explanation if relevant ? --[[User:Koundelitchnico|KoundelitchNico]] ([[User talk:Koundelitchnico|talk]]) 09:36, 24 September 2014 (UTC)

I made a playlist of the mentioned "Fun to Imagine" series of videos:

108.162.249.16:

When on xkcd, the emoji only shows up as an empty square. On this site, it shows up as a sigma, caputal Y with umlauts, tilde, and decree symbol. What is it actually supposed to be? [[User:Smperron|Kestrel]] ([[User talk:Smperron|talk]]) 12:46, 27 August 2018 (UTC)
:It's https://emojipedia.org/face-with-open-mouth-and-cold-sweat/ this emoji. Shows up correctly for me on the actual site on android but not on the wiki [[Special:Contributions/141.101.98.28|141.101.98.28]] 13:04, 27 August 2018 (UTC)
::It shows up OK (Albeit small) on Mac OSX [[User:BSchildt|BSchildt]] ([[User talk:BSchildt|talk]]) 13:21, 27 August 2018 (UTC)
:::For me (Windows, most fonts replaced with Arial) it's ok on the wiki, but on the page it's just ▯. But that might also be my font replacer messing up again, it often does that. I wonder why it doesn't happen here. [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 08:08, 28 August 2018 (UTC)

Does anyone know the source of the slippery symbol? The other symbols seem to be common to most standards, but the slippery symbol seems to have various designs. ☠☢☣⚡︎? [[Special:Contributions/162.158.62.57|162.158.62.57]] 13:52, 27 August 2018 (UTC)

The yellow colour, danger of sliping and radioactivity (previously mendtioned on xkcd) are all consistent with a banana. Could this be the secret message? I can stretch it to say that a banana left unattended might eventualy grow some biohazardous fungus. Is there anythng electrical or laser emitting about this fruit?

There is a legitimate hazard sign that combines 3 symbols. The new supplementary ionizing radiation warning symbol launched on 15 February 2007 by the International Atomic Energy Agency (IAEA) and the International Organization for Standardization (ISO). Contains radiating waves, a skull and crossbones and a running person.

:::TBH, if I were to explain the comic to someone else who hasn't seen it (in the words of the Editor FAQ), I would probably tell that there is a biohazard symbol, radioactivity symbol etc. But at least in this case, the caption below the frame clarifies the image a bit. [[User:Asdf|Asdf]] ([[User talk:Asdf|talk]]) 11:11, 28 August 2018 (UTC)
::::No, just describe the content. Only mentioning that there is a biohazard symbol wouldn't be helpful because many people just don't know how it looks like. And when the image gives no hint what it is everything further belongs to the explanation. Of course common items like cars or houses can be noted but identifying those symbols here is part of the comic and shouldn't be revealed in the transcript. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 16:45, 28 August 2018 (UTC)
:::::Fair enough. I meant by my earlier comment that I wouldn't have only mentioned the names of the symbols, but their shapes as well like in the current transcript. But it's true these symbols aren't universally known. The transcript should just explain what the image contains and not what is meant by those symbols.

The NFPA or fire diamond is not required or mentioned in the MSDS files. They are used almost exclusively on buildings that store the chemical and alert firefighters to potential dangers on entry. The MSDS has its own set of hazards that I believe he is referring to in the description/title. [[User:Piza|Piza]] ([[User talk:Piza|talk]]) 19:36, 28 August 2018 (UTC)
