this is glorious holy shit.
the bridge gave me Real Emotions, with the way you sang it, and the scene of the cop car chase. It's such an effervescent moment. I don't know what that word means, but that's just how I feel about it. I also feel like you can definitely go very far with your style of visual storytelling actually . It's beautiful, everything here is beautiful.
thank you so much for being yuu
thank you so much rae, your songs are always so thoughtful and your comments are too i've always wanted to make an animated MV like this, turns out oyasumination's the final piece I needed! 🥰
the oyasumination never disappoints--
even despite listening to it over and over for mixing, it just hit every single time
I hope I can see this Yuutaite go all out once more someday :)
AMAZING JOB PLAYING THEM VOCAL CHORDS
THANK FOR THE MIX
ITS HERE!!!!!
ITS HERE *shakes violently*
IM BALDING THIS SNATCHED MY WIG SOOO HARD YUU AAAAAAAA
how have i not found this sooner ??? already love oyasumination but your approach to it was nothing short of amazing ❤️
thank you!! 🧡🧡🧡
I loved everything in this cover, you’ve worked so hard for this and it’s all worth the amazing hardwork in the end. Your vocals, the art, the MV, your experssive tone and awesome range!!!! My gosh you made my day Yuu!!! Super proud of you and literally had tears streaming down listening to this 😭😭💜💜💜
MOOOSH THANK UUUU I CAN'T WAIT FOR MOOSHYYUMINATION 🥰
OYUUSUMINATION IS HERE LETSGOOOOOOO
HOLY SHITTTTTTTTT UR SO COOL OMGGGGGGG THIS WAS AMAZING OTSU TO EVERYONE WHO WORKED ON IT!!!
My guy went absolutely nutty with all aspects of this song well done Yuu 🥺😭😭😭
OYUUSUMINATION!! the final product is out of this world!! congrats on the release yuu and amazing work as always with everything you do :D
thank you yachen! :D
i loved every secondㅠㅠ and i never knew you could go that high😳
thank you hyunji!!! do you want me to whisper high notes at you in vc
I tasted the sun, thank you
Dang, I cannot stop listening to this. I'm not sure if your voice is tickling an old memory of mine, but this song sounds like those hip-hop rock kid songs that my parents would play on our living room TV. Your voice is amazing along with the instruments.
aw man thanks that means a lot
Wow this is such a cool MV! I love it great job!
I heard from you in on disc & this is my comfort song for right now. Been listening to it ever since it came out. GZ it's amazing, keep up the good work. I hope you don't mind but I shared it on another disc that belongs to MeatCanyon. I hope you get some new views this is talent! :)
thank you so much 🥹 I appreciate the sharing!
@@EuropaYuu Np add me if u want if not no worries I'm on discord all the time :D I love this stuff!
DISCLAIMER: I am a COMPUTER SCIENCE MAJOR and NOT A PHYSICS MAJOR. If i get calculations and other math wrong that is my copium. ALSO I THINK my initial calculations for the video I think were actually wrong so I will be reworking them in this new analysis. Ok let's begin.
In this analysis, we will be attempting to calculate the temperature of the ground caused by the friction of the "yuunosaurus" travelling at hypersonic speeds on the surface of an earth-like planet, as featured in the music video for Europa Yuu's cover of "Oyasumination" by the vocaloid producer ippo.tsk (at 1:17-1:21).
First, we will lay out and find all necessary data required for any following calculations, perform the calculations and discuss any interesting properties or attributes of the given scenario at hand.
To calculate the temperature generated by friction on any surface, given a moving (sliding) object on top of it, we must use the equation T = h * E, where T is the final temperature, h is the heat capacity of the given surface, and E is the energy generated due to friction.
1. Mass
Upon visual qualitative inspection, the yuunosaurus is a species of dinosaur that seems to be closely related to the tyrannosaurus rex (see here: imgur.com/gallery/332y3). According to the reputable source, Wikipedia, scientists claim estimates of adult tyrannosaurus rex to be from 5.4 to 8.0 metric tons. Upon further visual qualitative inspection, the yuunosaurus appears to be quite the girthy dinosaur, and therefore my estimate of its weight is on the higher side; at 7080 kgs.
m = 7080kg
2. Heat capacity
From the video, we can see the yuunosaurus travelling on the planet's surface at rapid speed. Given that the yuunosaurus is a terrestrial animal (lives/travels primarily on land), we can assume that the yuunosaurus is travelling on solid ground at all times. According to a quick google search, the average heat capacity of vegetated land is 830 J/kg/K (Joules per kilogram per kelvin). Also consider that the heat capacity of dry sand is 840 J/kg/K, average rock is 2000 J/kg/K, and wet sand is 1500 J/kg/K. However I decided to opt with the measurement for vegetated land as it was the lowest number, so it would yield a higher number in the final calculation and would therefore be funnier, in turn being more scientifically accurate.
Given the mass from the previous section we can infer that the heat capacity of the surface (proportionate to the mass of the dinosaur) is 830J / 7080kg, which comes out to h = 0.0117231638418J/kg/K. We will simplify this to 0.01J/kg/K as computer science is a part of the engineering faculty in my university.
h = 0.01J/kg/K
3. Normal force
From the initial equation we set out to solve, T = h * E, I see that we have no immediately obvious way to calculate the energy generated due to friction, and so we will require a few extra steps to achieve the correct result. We can use the equation E = Fn * d, where E is the energy due to friction, Fn is the normal force exerted on the body against the surface (in our case the yuunosaurus), and d is the sliding distance.
Furthermore, to find the normal force (Fn) we must use Fn = m * a, aka, Newton's second law of motion, where Fn is the normal force, m is the mass of the yuunosaurus and a is acceleration. The normal force in this case, is referring to the force the earth's gravity exerts onto the body in question, the yuunosaurus.
From previous sections, we surmised that the mass of the yuunosaurus is 7080kg, and we also know that the acceleration of a body due to the gravity on earth is 9.8m/s^2. From visual qualitative inspection, we can see that the planet featured within Europa Yuu's cover of "Oyasumination" by the vocaloid producer ippo.tsk is much like earth, and so we will use the same value.
This means that Fn = 7080 * 9.8 which equals 69384 Newtons.
Fn = 69384N
4. Sliding distance
Sliding distance denotes the distance of an object as it travels along a surface. This process of sliding induces friction. To calculate the energy of the friction of the yuunosaurus travelling on the surface of the earth, we must obtain a figure for the distance the yuunosaurus travels. Upon visual QUANTITATIVE inspection, we can see that the yuunosaurus travels about 1/4th of the circumference of the planet. If we follow our assumption made in section 3 in that the planet featured is similar to earth, the circumference of this planet featured in Europa Yuu's cover of "Oyasumination" by the vocaloid producer ippo.tsk, will be similar to that of earth. Earth's circumference is 40,007.863 km, which is almost as big as your mom's circumference. Given that the yuunosaurus travels roughly 1/4th of the planet's circumference, the sliding distance is equal to 10018.75km, which we will round to 10019km, given the assumption in section 2 in that the person running the calculation is a computer science student, which is part of the engineering faculty in his school.
d = 10019km
5. Energy due to friction
Given that we now know the normal force, as well as the sliding distance, we can now calculate the energy that the yuunosaurus generates due to sliding friction on the surface of the earth. But before that we must change the sliding distance in terms of m (metres) instead of its current measurement km (kilometres). This makes our sliding distance 10019000m. Now we can run the calculation.
E = 69384 * 10019000
= 695158296000 Joules
= 695158296 Kilojoules (required for next measurement)
6. Temperature due to friction
Now it's all coming together. We can finally calculate the temperature of the sliding surface of the yuunosaurus due to friction.
T = 0.01 * 695158296
= 6951582.96 Kelvin
= 6,951,309.81 Celsius
= 12,512,389.658 Fahrenheit (for you filthy Americans)
That's it.
7. Discussion (TL;DR)
As you can see from the figures given above we can infer a few conclusions. Here are some of the "worst case scenrio" conclusions:
a) The yuunosaurus just kinda uhh... blows up
b) Also the ground has probably melted and vaporized... or it's just blown up I guess yeah same thing
However if the yuunosaurus still stays intact, then that means that the material that constitutes the yuunosaurus has an incredibly high heat capacity and should be researched immediately (i.e. it's built different)
