Screw typical ASMR streams, I want a science podcast with fauna called "the natural order" or something.
What if we combine both? A whispered science podcast. I'd be down!
@@SentientSapling i would listen to that on loop
A better title is RULES OF NATURE

As my Physics professor told me: "The universe makes perfect sense. You're just confused because you're used to everything being larger than a proton, smaller than the sun, and slower than one-tenth the speed of light."
thats a statement that Im copy-pasting! :)
im stealing that quote thank you
Also stealing this quote
But if someone asks for sauce I know who to link it to
Thank you, I promise to reference Robert Jones's youtube comment from his Physics Professor
as my sister once said:
"nothing breaks the laws of physics, if it does it's either not a part of the universe or just a new part of physics we discovered"
Quantum physics is of course, quantum - Ceres Fauna
I thought quantum meant discrete
@@kv4648 no quantum is quantum
@@kv4648 well yes but no but yes
When a particle is at rest it has energy E0. Excited it to the first excited state E1 is a discrete amount of energy, no in betweens allowed.
String theory is made up of strings.
she said that bcs she wanted to describe quantum physics as physics only involving small things but actually you cant say that beacuse quantum physics involve quantum which is a "discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents."
As a scientist, hearing a popular internet personality say things like "our best models" and "it's just a popular theory because the math works out nice" and "you can never really prove something you just collect evidence to consider a theory probable" absolutely heals my soul. To hear science not necessarily described in detail, but at least depicted accurately in a way that simultaneously explains why the phrase "it's not a perfect science" is an oxymoron while also showing why you can and should trust the scientific method.
"If science had the answers to everything it'd have stopped." - Dara O'Briain
as my wise friend once said
"science is extremely educated guess"
As a particle physicist, this is a pretty good first explanation of string theory. It's very nice that she also talked about the problems with it
Haha. Love finding this video 8 months later.
Definitely not me who finally got this on recommended after 8 months and still watch it because SCIENCE
I'm showing this to my theoretical physicist friend!!
i'm the president of my country. real
I'm halfway through a physics degree, and I certainly didn't expect a vtuber to know considerably more about a physics topic than I do... ¯\_(ツ)_/¯
As a graduated physics guy, I declare this a common Fauna W.
She's quite a smart nut
Same
As an undergrad physics guy, I support said declaration.
As a graduated cylinder,
@@Bunndog as an overgraduated physical guy, I support my weight on my legs, unless I'm seated.
My Oshi is so freaking smart and I couldn't be happier.
Me too, me too
;))
This seems more indicative of being informed than being smart. If she knows how to do the actual calculations that's a different story though
@@hollowbrook947 true, knowledge=\=intelligence
@@hollowbrook947 The way I see it, inspired by some science on the subject, there are many different forms of being smart. Keeping oneself informed is one form and being good at calculus is another.
Fauna shows hints of a good educator. She starts with a presentation of the problem or the “gap” in knowledge, the proposed solution or theory, the general merits of the theory, the limitations of the peoposed theory, and finally the recommendations to push forward the theory. It’s deceivingly simplifed, but if this were a more formal educational setting, Fauna could legitimately handle the topic in an academic nature if she wanted to.
You think she's had experience in this? Maybe even a degree?
@@internetperson3436 i think she’s mirroring off the expertise of a professor she once had. If anything, she’s a good student or had a very good professor. So yeah, I’d say she has some kind of science/engineering background.
@@mikukumikuengineering fauna is so much cooler than any lore cover could give her
She is a biology major with masters degree
As a teacher with a PhD in quantum mechanics once said to me: if you think you understand quantum mechanics, go back and read it again.
i guess that's given if your field of study is all about probability and random chance(?)- wondering if a certain quantum particle exists or not. must be a headache to study, honestly.
I have always hated quantum physics and concluded it as a myth
That's just Richard Feynman
@@zapdosxy1781 problem is, it's a myth that *keeps accurately predicting the exact results we get experimentally*
It'd be like if I said "every internal combustion engine is actually 700 hamsters in hamster wheels that hide behind the engine block when you open it up", and you go to disprove it, and you never actually manage to see these 700 hamsters & their wheels, but the engine block mysteriously weighs less when you open it up, by exactly the amount needed to account for the weight of 700 hamsters and their associated wheels.
I've been told that also. After spending 2 years doing quantum mechanics research I have come to the conclusion that it still makes no sense
4:34, I can try to explain this one (I’m also a noob tho). Basically, quantum mechanics/particle physics says that every type of force is facilitated by a corresponding particle. (Light has photons, electricity has electrons, etc.) And this works for every single force, except gravity. If you try to fit “gravitons” into the established model, tiny balls of gravity interacting with each other on such a small scale would create tiny black holes everywhere. And that isn’t happening, so…
String theory proposes that every particle is actually a vibrating string, and a graviton would be a string connected end-to-end in a loop. This effectively makes gravitons less dense, since it’s not a solid uniform shape anymore. And this apparently makes the math work out really well, and then you don’t get tiny black holes everywhere, which is cool. That’s how String Theory ties quantum mechanics and Einstein’s gravity together.
Okay, but if someone ever asks me to describe how I learned this unified theory, how do I describe the context of this comment without also explaining what "moe" is?
@@Niffoni just say you learned it from PBS Spacetime or something lol. Veritasium is good too. I personally watched a lot of Sean Carroll videos, but that’s like hours and hours of stuff
@@kingofvwcosmos "Idk, it feels like that's just how things are, as if nature herself told me"
I would have to make a addition: Quantum mechanics is actually the description of the behavior of particles (doesn't describe what it is). Particles behave as a "wave" (in that we cannot deduce its position, only the probability of its position, which, likewise, its movement, so more specifically, its a probability wave). Check out the double slit experiment. Its the most basic way to visually understand quantum mechanics.
In easier terms, relativity is deterministic, quantum theory is probabilistic. The reason why its hard to combine is because of the inherent contradictory nature of these aspects.
String theory proposes a description of gravitons can can fit in with both general relativity and still matches quantum theory. How....
Most of it is a bunch of math (including probabilities) of course. Its literally using math math to explain math. There is no actual easy way to explain it. I mean, can you even imagine 11 dimensions? On paper, its just 11 variables. In reality its ??? And this isn't even including the different mathematical interpretations of string theory which are explained differently.
@@kingofvwcosmos i like that quote. Please allow me to use this particular sentence in my day-to-day conversation. It's urgent.
i don't know the vtuber scene, but holy shit this girl is playing getting over it VERY calmly while explaining string theory and quantum mechanics.
it is surreal, and this is why i fucking love the internet.
Welcome, brother. The rabbit hole is deep and interesting
Not only that, she's trying to get the golden pot which you get after beating the game 50 times, if you look at the bottom it says she's beaten it 19 times already
@@webpombo7765 i think i underestimate her brain capability to keep replaying the game
When she does Bennett foddy's job better
I want an asmr where she just explains physics theories
Bro you literally read my mind, except I'd be fine with her giving a normal lecture.
Then you cannot proceed to sleep because you keep on wondering how those things happen.
Imma need fauna to make a 2 hrs of that. And tell my physic prof to turn it on during class
These subtitles are very helpful since I'm an intermediate English learner and esp these kinda topics are really hard to keep up with without subs. so thank you!
I am happy to hear the subtitles helped someone!
Me too, subtitles helps a lot when English is not your first languaje
@@SentientSapling yeah, they really help! Indispensable when you're just starting to learn listening, and useful from time to time with accents in any case. Although Fauna speaks very clearly, she does have a slight unusual accent, so subtitles are very nice to have.
@@Sergei_WHY Since I like to add animations to the text ot may make it a bit difficult for some people to follow all of it, but good news is that the auto generated subtitles are now working as well and are at least somewhat accurate. Not sure how good the translations are though.
Always remember that “a lot” is two words. It’s the same as “a bunch,” which is easier to remember as two words
Normal streamers playing this game: AAARGH! OMGWTF!
Fauna: *calmly explains the trifecta of scientific cosmological theories*
The fact that we’ll never get a stream where Fauna and Sana talk about space and physics makes me upset.
man...
Fuana is explaining physics while playing the most rage game on the planet her brain is so big that the universe can't even measure her smartness
I'm halfway through a physics degree, and I certainly didn't expect a vtuber to know considerably more about a physics topic than I do... ¯\_(ツ)_/¯
i second this
Knowing the surface is one thing. Being able to swing with the math is something very different.
I find that hard to believe. This is documentary level information.
lmao
@@TheDarkLasombra but she knows the math
As someone currently taking graduate quantum mechanics, I can say that Fauna’s explanation of QM is perfect. Quantum is indeed very small.
Cue in ant man movie theme.
😊
Planck length: you gotta pump down those numbers
The sexiest fauna clip.
Definitely
Most certainly
This has to be by far the chillest most relaxing explanation of physics I’ve ever heard ❤
She even ends it with *boop boop*
she's got the patience of a saint, if she repeatedly fucks up like that and her voice stays completely calm
Watching her talk about such an academic topic while failing the same jump upwards of 40 times is really great ngl
There are clips of Sana trying to explain string theory to Kronii, it s really funny since it completely went over her head. (and space and time talking about space and time lol) Ever since then I wished someone can to Sana about it XD
Iirc what we teach in schools is special relativity. Einstein wasn't exactly right either, its just that his theory was refined by other scientists into a more comprehensive one.
Somewhat same story with String theory, used to need 29 dimensions and predicted the Tachyon which goes faster then light, but was eventually refined to 11 dimensions and no tachyon, so it stands to reason that it can be refined again. Testing it is another issue alltogether still, putting humanity in another Planet X situation
Thanks for sharing, it's been awhile since I had read up on anything.
As an aside Tachyon is a cool word, lol. Would love to see Fauna try explaining it to everyone in a collab.
@@SentientSapling I luckily ran into some videos months ago which explains the basics concisely. I forgot which ones though, previous videos on the topic just confuses me more 😓
I still miss Sana :(
special relativity only takes velocity into account, it completely ignores gravity. General relativity is the more complete theory.
Those were especially funny since Kronii put on her "disturbed" face pretty quickly, and that combination combined with her obviously-bluffing "yeah, okay, uh-huh, yeah" was gold.
Love the new episode of The Big Holo Theory, especially when Fauna said Bazinga.
Wow! Cute, soft-spoken, and likes Physics. Thats a deadly combination lol.
This is why I think Fauna is the smartest Hololive member
@@SaxonBlue5771 botan ís smart in general knowledge, or what we usually called a wise elder. But fauna's math and science is exceptional. I dont remember any other hololive member that explain complex science topic beside fauna.
Oh, millie from niji also major in science, but she never discuss about conplex topic.
There's different between smart and knowledgeable
@@I_like_modeling_Monsters922 NijiEN's Luca also had a STEM major, and I think Shu did programming? That's about my extent of knowledge on the topic though.
I think Ollie is pretty smart
@@Egg-san Yeah, Ollie's mathematics knowledge is definitely at a higher level than most people would learn unless they majored in math in college.
I love it when she gently whispers quantum physics in my ear
As a physicist I can confirm these words are indeed used in our field.
Listening to quantum physics and "uuuu" next to each other is the pinnacle of human civilization
Knowing that even physicists, literally our reality hackers, feels humbled by the great unknown in front of us, also humbles me in ways I cannot fathom.
It's natural to mother nature to know about physics
Fauna physics lecture + muted getting over it + rain sounds = heaven
We don't get to hear Fauna nerding out about science very often, but when it happens it's always a delight.
“It’s just a theory”
A STRING THEORY
It boggles my mind (and is also hilarious) how she understands string theory and can explain it pretty well to the saplings, yet couldn't figure out how to launch off the anvil for half of this video (especially considering how much she'd done it before this point)
That's what I'm saying 😂😂 I was thinking the exact same thing.
Lol, I mean, can you imagine trying to explain String theory well and play a game well? People are super bad at multitasking, I basically cannot talk and game at the same time, lol.
@@Chex_Mex yep, pretty sure this is her having a hard time multitasking, especially in this game. it's really hard to multitask unless you already did 100-200 run and the game is mostly muscle memory
Her explanation of string theory is both accurate to a reasonable degree and easily understandable, and she even briefly explains a little bit of Super Symmetry. It's clear Fauna actually does know her stuff
I was not expecting an accurate explanation. I like this. I want more of this.
Since people were asking for more Fauna talking nerdy, here is a biology tangent on slime molds!
ruclips.net/video/h51f4h8AO8g/видео.html
And a tangent on Eusociality in animals with emphasis on bee lore:
ruclips.net/video/RYSVFJshT_s/видео.html
What the hack
I think the main idea is the string vibrate like a guitar a string. The different "notes" are different vibration speeds/frequencies. Roughly the "notes" are what make up quantum forces in quantum science. You can also combine notes to make larger "chords" which just translates to bigger quantum particles. It's been a while since I've studied this so take this as just a rough idea.
I love how you can feel the excitement on her voice on certain moments while she’s explaining this
I need more fauna physics moments
I can tell she has a bunch of stuff on her recommendations lol. I really like engaging with these kind of people. They’re very open minded and enjoy going into a discussion no matter how taboo the subject is
String Theory is taboo?
@@JoseRodriguez-eu5ez lol not in regards to this conversation.
@@JoseRodriguez-eu5ez no, what they're saying is that those people can talk about some very sensitive or controversial stuff and will still be mature and open minded about it
@@Azurval
The point is that I was poking him for saying String Theory is taboo here. Or anywhere else, really.
Unless I walk into a room full of theoretical physicists and say it out loud. In that case, I'll be having strongly worded conversations left and right about how fundamentally insane I am.
The comment itself is a roundabout way of saying he likes this VTuber, which needed no explanation, really.
@@JoseRodriguez-eu5ez cool cool I was just trying to explain my man. Some people are actually serious when they ask questions and I have a hard time discerning sarcasm when I don’t see the person being sarcastic face to face✌🏼
I need more clips of Fauna talking smart
Dang why am i only seeing this clip over a year out. Fauna would have become my EN oshi waaay sooner lol
Watching this clip gives me an idea to watch a VTuber/teacher casually teaching and (maybe) playing video games at the same time like Fauna did there. It can be an inspiration for students to learn more.
Fauna's beautiful and soothing voice makes listening to theoretical physics fun.
(I'm just kidding, I'm actually a nerd who likes physics theories)
You and me both
I misread that as "physical theories" and my mind now requires a cleansing.
She's got a nice voice but I definitely wouldn't describe it as "soothing"
Well i am both of what u said >:)
Fauna going on a spiel about science is surprisingly satisfying to listen to, even though it's usually boring. It must be her voice making it interesting. 😆
Also that "boop boop" at the end is _so_ adorable. ❤
Faunas ability to remember specific names of things will never stop amazing me, like remembering this concept and idea and being able to explain it isn't as crazy to me as when she just whips out scientific names throughout, or like the other day someone just described a crime in chat and she just knew the guys obscure name instantly. I wish I had that super power in school lol
Fauna was most definitely a physics major
100%. I'm halfway though a physics major myself, and she knows way more about this topic than I do ¯\_(ツ)_/¯ (and the fact that she says she "can't remember" things means she knew more in the past)
Biology actually. Back before Fauna she told us her degree was in Biology. She used to do research.
@@TheAHuman Really? Do you remember when did she mention this?
@@TheAHuman How fitting
@@TheAHuman I would've guessed Chemistry. Maybe she specialized in biochem to gain this level of understanding in nuclear physics.
As a chemist, we cover a lot of quantum mechanics (-shudder- Physical Chemistry), so I’ll let the Physicists cook. Also, low key, Physics people are so cool, I’ve met so many happy Physics people and I respect it.
What an amazing explanation, to be able to explain it "like I'm five" while also having attention on the game is quite a feat
I think the only inaccuracy was at 2:05 - black holes do not have infinite mass
One thing to help you out is to remember that String theory is an hypothesis, theory means that the hypotheis has been tested and has become gernerally accepted.It is strange they call it "theory" even though it should be called string hypothesis, though i guess colloquially it makes sense. Other than that great layman explanation! you got a sub from me! ^_^
I totally agree, it would be very difficult to use the basic scientific method and use experimentation to have data for this hypothesis.
The moment when you're procrastinating for your quantum physics exam and this pops up in your recommended. I know I need to get back to it, didn't need youtube to make me feel even worse
Such a knowledgeable V-Tuber, I wish we get more science majors as Hololive V-Tubers in the future.
The rain sounds fit so well
I am thankful to have discovered this clip.
I like when I'm being explained complex science in understandable terms without feeling like I'm condescended towards
I'm so glad this video got recommended to me. Imma sub to Fauna now.
Glad to hear! I really like her content - I hope you do as well! It is usually pretty comfy/relaxing with slight moments of chaos and these awesome tangents.
...I really should start watching Fauna more often.
Thanks for the clip!
As the keeper of nature, Fauna's knowledge about things like quantum physics makes perfect sense.
As a chemist who learnt physics at undergraduate level i am surprise she actually knows what she said
Fauna flexing with her big Brain and massive Knowledge right here xD
I love the more complexe topics of Physics and Theories. However, I'm not doing to well right now, otherwise I could have shared some thoughts. My Brain ain't working well enough when sick
Hope you feel better soon :)
I really want some Hololive streams focused solely on education or weird facts.
It’s encouraging that there’s actually an audience that wants that
Vtubers doing video essays when?
i never thought that those 2 world i enjoy the most would collide but here we are... Physics and Vtubers. I gonna simp for that dude
Need an asmr with Fauna talking about quantum physics, string theory and all her science theories 💖 with that background effect of rain 😍
Many physicists work with math up to the 11th dimension. A problem with math higher than the 3rd dimension is that it cannot be graphed because we cannot graph something that cannot be observed. Since we live in a 3D world, 3D is the most we can graph.
This video made my physics heart love fauna even more
This isn't the aspect of nature I expected from Mother Nature, but I'm here for it.
I don't mind her being the substitute teacher, heck i would her to be the teacher herself
Start the Hololive classes. Fauna is the science teacher. Ollie the math. Who else?
@@TheAHumanIna is the art teacher, Kiara is the language teacher, Ame is the biology teacher.
@@PlaguewielderAlchemist Calli is the music teacher, Aki is the dance teacher, Gura/Chloe are the swimming instructors
Yeah, unification, the ultimate uniting all scientific disciplines that are in seeming disagreement has been the dream of all physical scientists for a long time.
Einstein famously had a problem wrapping his head around quantum mechanics. Quantum entanglement, or the ability of two quantum particles to have opposite spins in perfect sync regardless of the distance between them, was always referred to Einstein as "spooky action at a distance."
This is unbelievably relaxing...please explain more science to us!
ive only really listened to fauna's asmrs so i dont know her very well outside that. this clip got recommended to me just now. i already enjoy her asmrs but wow i didn't know she's also well-versed in science stuff. hope she considers doing science themed asmrs as well. that would be fun
wtf this actually made me interested in physics now
I thought this was going to be memes and haha moments. I was pleasantly surprised that it's actually a monolgue talking about physics.
We've reached the point in society where anime waifus are explaining string theory and quantum mechanics to me while jumping around in a cauldron with a hammer, and I don't know how to feel about it.
feels good man
“We need a way to trick the young into learning.”
“I got an idea…”
"I've already 😊done my rant 😊about string theory 😊so what is even left 😊in this world?😊" -Ceres Fauna, 2022
As someone who's doing his physics bachelor right now I can certainly say that it wouldn't matter what fauna says...I'd believe it
This one clip filled my recommended page with science videos, thanks Fauna…
I can’t tell if this is coming from 8+ years of formal education or 8+ RUclips videos binged the night before recording this.
This is the most attractive thing I’ve heard all month, NGL.
String theory is group theory.
This is how chemistry organizes things. If you can identify certain traits of a chemical, then you can associate it with a specific group of chemicals. If it is associated with that group, then you know the properties of this unknown chemical. If you want something more specific, well that requires further testing.
Likewise, string theory supposes different particles belong to specific groups associated with a physical law. If you can identify key characteristics of a particle then you can toss it into one of these known groups. Hence, the ability to predict certain particles existing.
Group theory has a very specific meaning in mathematics where it is a whole field of mathematics concerned with symmetries. Also grouping of things into categories wasn't invented by chemistry lol
@@sindhurtej9638 I don't believe I wrote that Chemistry invented group theory, just that it utilizes it.
Yes, group theory goes deeper, but that us not necessary for the discussion.
You are using formal logic to relate two unrelated processes of research based on their external similarities. Theories may accidentally correlate sometimes, but the only right way to understand the logic of any theory is to learn about its real history of development (including the context where it arose out of necessity). It may be tempting to deduct it from externally similar theories, but the similarities are not scientific basis.
But then again I am commenting on a video about an anime girl so maybe it's not that important? 😅
@@sieunhan00 when you think of the RUclips comment section, what level of education do you expect?
So anyone who wishes to make something abstract concrete enough for said audience. Must jump through hoops, and be careful of "lies for children."
All of this to say, I choose group theory as it logically does what was described of String Theory. If someone wishes to learn more, than understanding better, but more abstract, prospectives will require a concrete basis.
That's fair.
Cute girl with a soft and sweet voice lecture about advanced science theories is something I could never dream of.
As a hooters host, this melted my brain.
I like string theory too lol! It just makes sense. The big bang being gods "pluck" of the big string we call the expanding universe and all matter is the resonance of that action.
I wish Sana was there. Would love to hear them discuss the topic together.
0:09 It's just a theory. AAA STRIIIIIIING THEORYYY. Thanks for watching!
there is a very good ScienceClic video that explains the very basics of string theory and superstring theory (doesn't include the calabi-yau stuff tho)
A cute anime druid teached you about the wonder of the universe. Truly what a time to be alive
If only *Sana* and Fauna had a Physics stream collab before she graduated.
One word to describe this. “Bazinga.”
My physicist ass would absolutely love a “Studying String Theory w/ Fauna” stream
Old clip now but it's my first time seeing it and man, this is exactly the kind of subject of yapping that I need from a creator.
If only funa's-san physical ablity of game play was as better as her theoretical physics then the whole game would have been completed in the mere span of 7min and 16sec.....
Vtubers trying to be coherent about physics seems really endearing. If you want something similar, there's a a group of vtubers that hosts a livestream about space-related physics (宇宙を学ぶラジオ) every 2 weeks or so by astronomer Hayashi and co-hosted by Tomoshika Hikasa and Dizm. It's in Japanese though but there's usually somebody in the chat translating it. I hope more vtubers talk about cool stuff like this.
Plank length is what Fauna was grasping at. A very nice explanation.
Everything super soothing and you just huuuuuuuu boop boop
me need more Fauna taking over the role of the enlightened science enjoyer for Sana
I just love how a kirin soft spoken vtuber explains physics .
Makes me love Fauna more.
I might like to add to the topic:
When Newton proposed the laws of gravity it really helped a lot. In fact it helped us discover Neptune and Uranus, but it falls on correctly predicting the orbit of Mercury which lead to propose that there might be another planet but they can’t see it. Until Einstein came and predicted it correctly.
That’s what good about Science, we take steps and improve it thus making it better.
Why did I instantly fall in love with her after her explanation? Fellow Physics majors
This video is the one that sent me down the rabbit hole and is why to this day even though I watch a lot of different hololive members, fauna will always be my oshi
I just kind of want to note that black holes do not have infinite *mass* but rather infinite *density*
The rest, I’d say, is close enough
