Official Calculations Discussion Thread

[Omnificence]

Hey, so I've been looking for some volunteers to calculate a few feats for a couple of Devilman threads that have been in limbo for quite a while. Does anyone here mind giving input in them and see if they can calculate some of the feats ir is this not the proper place to ask? Thanks!

Bump here?

Godzilla drilling a hole got recalced, can someone check it out? (watch me post this in the wrong thread)

1) A large mass the size of a body is noted as a perfect sphere. A perfect sphere is a mathematically hypothetical shape, does it have any special characteristics or it's just an aesthetic unique body?

2) if you wanted to calculate the force needed to wipe the entire solar system (including the oort clouds), would you still use the inverse formula with the sun's GBE?

 

[MonkeyOfLife]

how would one use vaporization + the timeframe of it?

Let's say an island with a 10km diameter were vaporized in 1.5 seconds... How would you calculate that?

 

[Mr. Bambu]

Such a minuscule timeframe wouldn't really be worth paying attention to, generally. If you question expands to be, say, 1 minute or 30 seconds, we would divide the net result to get watts.

but how wouldn't a fast timeframe of destruction not be worth paying attention to? If something vaporized very quickly wouldn't that give higher results than something that vaporized not as quick?

Like if a rock vaporized at sub rel speed and a rock vaporized at around explosion speed... Wouldn't that give completely different results?

 

[Mr. Bambu]

1 second is our standard for "instant" with calculations. 1.5 seconds is close enough to this margin so as to render it essentially identical, especially with other weird factors of on-screen factors potentially changing how long it actually took in-universe.

Yeah, technically the math would be different, and for speed you'd have to observe it anyways (time being a necessary part of the equation). But something so close is rarely going to be a huge change.

Editing this message to add that as a wiki, we work within fairly generous margins of error most times, simply because fiction often does not afford us the ability to do otherwise. Half a second is by all accounts in the margin of error.

 

[MonkeyOfLife]

so a 10 km island vaporizing in 1.5 seconds, the vaporization speed would be 6666.67 m / s

Do you just combine the vaporization/destruction energy and the kenetic energy..? Or?

That's the thing I'm trying to figure out

...kinetic energy lol?

 

[MonkeyOfLife]

...kinetic energy lol?

lol I guess I pronounce/view it as kenetic... Don't understand how i Is an eeh sound in English problem with the US language fr

 

[Mr. Bambu]

Could you post the specific feat you're talking about? I can't envision a feat where you'd be getting both vaporization and kinetic energy from the same parameters, is all.

uhhh... Sure

The thundercloud itself is dense enough to destroy/crush buildings

And the lightning explosion destroyed/vaporized the thunder cloud and the island cloud as well which replicates normal islands, being dense enough to carry buildings, people and even part of an actual island (as well as act as tires), so I would just use normal earth density for it

The anime gives a timeframe of 1.99 seconds (the destruction sound appearing and disappearing) which I'll use for mid-end I guess and I'll be using lightning speed for high end

Low end is only just the vaporization of stone's density

 

[Mr. Bambu]

Clouds are already vapor.

(I'm not sure I'm understanding, for the record, since that looks like a giant ball and you're using stone characteristics, so if I'm missing something, do enlighten me)

 

[MonkeyOfLife]

since that looks like a giant ball

the giant ball is called a thundercloud, that "small" one destroyed only angel island, the big/bigger one was going to do the same thing to all of skypiea which includes also an actual island

Several km = at least 3 km (radius) making the diameter 6 km of the big thunder cloud

 

[Mr. Bambu]

If that is straight up a giant ball-shaped thundercloud, then yeah, it'd already be vapor (even with higher density). Can't vaporize it.

If it was destroyed, maybe dispersal is more what you're after?

but you can vaporize clouds... What you mean?

It was destroyed via being vaporized... Not really

It was going to vaporize an actual island anyway... But the cloud island replicates normal islands (which the clouds would have a similar density to earth/stone) the same way the sea cloud replicates the sea

Clouds are condensed water vapor that will soon form into liquid (that is, rain). Some percentage of a given cloud is water as liquid, I suppose, but the cloud itself is largely already vapor.

As for vaporizing an island, I'm unsure how this would correlate to KE, but yeah, that can work. I'm fine with the idea of the island cloud being treated as earth-like if presented as such.

Yee true but that first comes from the suns heat into the sea which then makes stem from the water which then turns to cold clouds.. (says they become water droplets) basically making it similar temperature to water? Which is how it can be vaporized I’m assuming

(Wait some clouds are even colder than the sea 👁)

I'm unsure how this would correlate to KE

Well I assumed since the moment of impact/vaporization, the effected area would have to move aswell before turning to vapor and decreasing in speed. Making another method via KE

At what height does mgh stop being used for P.E, in favor of the more complicated formula?

 

[SeijiSetto]

At what height does mgh stop being used for P.E, in favor of the more complicated formula?

I can't think of any specific hard cut-off point, but I personally would stop using it at ~330,000m, as that's when the difference between them crosses 5%, which I consider too significant of an error to be handwaved as just general inaccuracy.

Can I have a hand here, please? I'm still trying to teach @Kingcollapser how to do calculations.

 

[Ednaxel2]

Can anyone please check this calc out? It's fairly simple
