#math is fun

In "How to pick your dragon" (s1, ep7) Hiccup says that they could fly the distance, a boat needs 2 hours for in 5 minutes.

In "Crushing it" (s3, ep8) Gobber says that it took him one week to travel from Berk to the Edge.

So, if we ignore all physics, different dragons and logic:

1 Week = 168 hours

2 hours boat = 5 minutes dragon 168 hours boat = 420 minutes dragon -> 7 hours by dragon from Berk to the edge

The average viking boat was sailing with 7 knots. 7 knots = 12,984 km/h

168 h * 12,984 km/h = 2.177,9 km (=1353,29 miles) from Berk to the Edge.

Sincerely, A fellow person who also gets really confused by time math

Unfortunately I have made up my mind about how the timeline would work, obviously the events of PHM is earth years and the years Rocky tells Grace is translated to earth years, with the exception of the time he spent with Adrian as I'm debating if I'm makeing that Erid or Earth years.

Which means that the time Rocky spend in space is much longer on Erid terms. So the PHM part of the timeline isn't too broken to say the least as well as past timeline on Erid.

But after they come to Erid everything will still be said in earth years for you guys but the time that passed is Erid will be in Erid years which does slow down Grace's aging by technically.

[As I am typing this I realised I didn't bring out my calculator which fuck why past me why didn't you put it in your bag, now I need to use the old fucking model at my parents place.You do what you got to do]

So Grace's age on Erid is probably the most complicated one and I need to make a separate post to explain it properly.

Infinity mirror cube is available at our store:

then i looked at it a little longer and thought. huh. i dont those equations would work like that. so i plugged the provided parametrics into desmos and discovered

i was right! it's bullshit lmao

evidently this person just asked ai to draw a heart on a pair of axes and made up some complicated-looking equations that would sound vaguely real if you didn't think about it too long. however, i am a pedantic piece of shit.

you CAN make a heart on a graphing calculator, but not with sine/cosine waves. without any limits they just go for infinity. once again AI is full of shit.

the graph you want is 'x²+(y-√|x|)² = 1'

which gives you this

We’ve all seen Dracula pull his epic "poof into bats" move. But let’s get real: how many bats would that actually take? Time to crunch the numbers, vampire-style!

The Data:

Dracula’s Stats: Bat Stats (folded):

Height: 1.93 m Size: 5 cm × 3 cm × 3 cm

Weight: 90 kg. Weight: 30 grams

I don't know Dracula's exact height or weight. But I found this exact information somewhere on the internet. I apologize if it's incorrect

Part 1: Volume Calculation

1. Dracula’s Volume = Weight / Density

V= 90kg/1000kg/m³ =0.09m³

2. One Bat’s Volume = Length × Width × Height

Vbat = 0,05×0,03×0,03 = 0.000045m³

3. Number of Bats = Dracula’s Volume / Bat’s Volume

0,09/0.000045 = 2000 bats

Verdict: Dracula turns into 2,000 bats, enough to have a hell of a flash mob in your living room.

P.S. Density is the bridge between “how heavy” and “how much space”. If Dracula were made of air, he’d fill a whole room. If he were gold? He’d fit in a backpack. But since he’s human-like (and humans ≈ water), we use water’s density (1000 kg/m³). It makes calculations easier and doesn't make physicists cry

Part 2: Weight Calculation

If Dracula’s weight stays the same (90 kg), bats gotta add up!

Number of Bats = Dracula’s Weight / Bat’s Weight

90kg/0,03kg = 3000 bats

Oops! 3000 bats would need 3000×0.000045=0.135m³ — 1.5x Dracula’s volume!

Verdict: Dracula would have to break the laws of physics to hold so many mice. Or... they have to be super dense.

Part 3: How do you combine volume and weight?

To match both weight and volume, bats need Dracula’s density (1000 kg/m³).

1. Bat’s Volume = Bat’s Weight / Density

Vmagic bat = 0,03/1000 = 0.00003m³

2. Number of Bats = Dracula’s Volume / Bat’s Volume

0,09/0.00003 = 3000 bats

Verdict: If the bats are 5cm x 2cm x 3cm in size, they will fill both volume and weight perfectly. But these mice will look like mini bricks - not great for vampire transformation.

Final Showdown

According to science: Dracula can become 2,000 mice, but their weight will only be 60 kg (where did the other 30 kg go? Maybe it's a raincoat?)

Magically, 3,000 brick mice that will keep weight but raise questions among physicists
