Editing Talk:2681: Archimedes Principle

<!--Please sign your posts with ~~~~ and don't delete this text. New comments should be added at the bottom.-->
I started an explanation, but I can't really figure out what Archimedes' "plan" is. I guess it has something to do with swapping out the fake crown with the king's real gold crown. Heist movies and TV shows always confuse me (I liked "Leverage" for the characters, but could never understand the plans).

:Under the guise of demonstrating the displacement principle (the buoyancy effect has no real part in this, given the non-floating nature of any crown... I think the focus in the explanation should just be upon the displaced volume of liquid which traditionally would quantify the volume of an object of known weight and a density to be tested to ensure it is that of the purported substance) he will dunk the real crown in the water. Then ''either'':
:* extract the fake crown, now 'proven true', satisfying everyone but leaving him the really-true crown, or,
:* extract the fake crown, possibly fudging the interpretation (how much water sloshes out) to make it ''seem'' like a fake crown went in (and the fake that came out can now be destructively examined to confirm this, now having just cause to utterly ruin the craftwork in the process, and framing the original artisan for fraud), again leaving him with the crown he was given for testing.
:If the original crown was itself already fake then it might not be worth it (or have to lean towards the latter outcome with a bit of extra care not to 'upgrade' the fake) but that's probably covered by the typical Batman Gambit of a typical heist movie characterm [[Special:Contributions/172.70.85.49|172.70.85.49]] 00:37, 6 October 2022 (UTC)
::The first of the two options makes way more sense. I don't like this plan at all though. How do you hide a colored shiny thing in a bucket of transparent water?!? I feel like we're missing something obvious. [[Special:Contributions/172.69.34.80|172.69.34.80]] 01:53, 6 October 2022 (UTC)
::Megan says "hidden IN the bottom" , so I think there is some kind of false floor/double bottom at play here; allowing the fake crown to be hidden from view and allowing for a crown-swap in the middle of the demonstration.

::Nobody said that it was clear water.  Pond water could be dirty or murky enough that the scam would work without the need of a false-bottomed bucket. [[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 04:24, 6 October 2022 (UTC)
:According to legend, Archimedes is given the king's crown in order to test for its purity without breaking it; he suspects that the goldsmith he hired replaced most of the gold with silver and kept the excess to himself. Archimedes uses his displacement principle to measure the volume (figuring the principle out in his "Eureka" moment) and weighs the crown to determine its density; his results imply that the crown is in fact fake.
:Here it's implied that the real crown is actually gold, and Archimedes is taking advantage of the king's paranoia; he's likely planning to switch it out, perform his experiment on the fake crown, and keep the real gold to himself. --[[User:Account|Account]] ([[User talk:Account|talk]]) 03:50, 6 October 2022 (UTC)
::Which could indicate that the successful execution of Archimedes' plan is what leads to the legend as we have it today.[[User:MarquisOfCarrabass|MarquisOfCarrabass]] ([[User talk:MarquisOfCarrabass|talk]]) 05:40, 6 October 2022 (UTC)
:::Yes agreed. The King was paranoid and his crown made of gold. And the reason the legend says he proved the crown to be false, is that he did this heist to steal the real gold crown. So for a bit of gold and some silver he gained the same volume of gold, that could be either melted or sold to a secret bitter --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:04, 6 October 2022 (UTC)

:xkcd does Archimedes's Heureka, Gotlib does Newton's apple...any more examples of (not necessary comic medium) parodies of famous science history anecdotes? [[Special:Contributions/172.70.242.7|172.70.242.7]] 06:27, 6 October 2022 (UTC)

Why is the image on here so blurry? I'd edit it, but I'm not sure how to do so myself. [[Special:Contributions/108.162.241.163|108.162.241.163]] 18:18, 30 October 2022 (UTC)
:Ironically, I think it's a result of the _2x image being downloaded but being displayed at 'low'-res size (theusaf has channged the procedure, recently, to grab the bigger image but then put in the directive to show at the smaller dimensions).
:Comparing this page on one tab and the two "source" images on other tabs, at least in my browser (if it's not how the wikimedia gets served - I haven't dug deeper into that just yet) it seems to downscale slightly less nicely than the 'preshrunk' standard version.
:But that may be as much my eyes/screen. I suppose I should screengrab and examine ''those'' pixels in a further zoom level to try to get a definitive idea of where the 'problem' lies.
:That said, I don't find it notably detrimental... Didn't really think there was a problem until I saw your comment and did the above comparison for myself. [[Special:Contributions/141.101.99.22|141.101.99.22]] 19:14, 30 October 2022 (UTC)

I get the feeling that running naked through town is the punishment Archimedes is expecting to get when he's caught... [[Special:Contributions/162.158.222.173|162.158.222.173]] 14:24, 28 November 2023 (UTC)
