- What is turbulence and why does it happen? Explore the phenomenon that has perplexed physicists for over a century.
--
You’re on an airplane when you feel a sudden jolt. Outside your window nothing seems to be happening, yet the plane continues to rattle you and your fellow passengers as it passes through turbulent air in the atmosphere. What exactly is turbulence, and why does it happen? Tomás Chor dives into one of the prevailing mysteries of physics: the complex phenomenon of turbulence.

You forgot 2d flow and fully developed!!!!
When I read "... neglactable" I'm happy
Turbulence:
Everyone: OMG WE’RE GONNA DIE
Baby: Yay~*
bruh moment

No turbulence is strong enough to break the airplane.
@@mohammadzohorul8887 MAYBE VOLCANO CAN STOP AIRPLANES
I wish they were like that on every plane ride
As a pilot I can confirm the turbulence button is right next to the chemtrail button.
what's chemtrail?
@@shudha5214 it is a Conspiracy theory
Keys879 idk but on airbus i fly its kinda far away from that :^
@@mcwatcher7790 why won’t it let me read more
Good troll. However, there’s no such thing as a chem trail. It’s a contrail or condensation trail. So basically, some nuts act like clouds are bad
Me: poops in the plane bathroom
The pilot: we are currently experiencing turbulence
Turbulence is a plane accident that caused from large heap of wind
@jingyu byun Actually most airplane passanger cannot go to the toilet while having a turbulence....They also wearing selt belt until it safe to move around.... Sorry for my bad english:)
@@zarifaiman5005 What if he's already in the toilet when turbulence begins?
Haha
@@weijianlim4431 i dont know if you get the joke or not
1:20
this guy brought lighter to the plane!?!?!?
absolute madlad. bet the security only took away his water bottle.
Lighters are allowed on the plane, better yet if you want to bring one you have to take it with you, you arent allowed to have one in your luggage
3:13 Animation error.
Ice cubes also float on water.
That's a glass cube then.
Present Lee wut
Just entered the comments searching for this hahahaha
Your avatar kill me :D
Maybe the ice cube was dropped from a height that generated a force greater than its bouyant force and just before it started to float the animation stopped 😂

Underated coment
Hi Daniel.
WTH ARE YOU DOIN HERE PAL
Hi!
even more mysterious..can occur with any one at anytime anywhere..lmao!1
ye, help me with that. so I could answer my communication assignment
The animation at 1:50 is from the Chanel “Think Twice “. Really recommend if you like maths or aesthetically pleasing thing
its literally written on it
@@npc4416 this comment was before they updated it
@@owlesent oh thanks
"Despite how difficult it is to explain turbulence mathematically, Vincent van Gogh was able to capture it with astounding accuracy in his iconic painting "The Starry Night" - so smooth ~~~
even if there is no explanation ,ted ed will give you so many probabilities with best available science .
you are right i agree with you
@@mennatallah4068 Arabic
Did u realize they make the animation wrong, becuz ice cube will always float on top of water
Factz💯
@@rancor4513 correct 👌🙂
A whole buncha turbulence
I’m actually studying dynamics of fluids and I’m very invested into it..
seeing this little introduction to it makes me acknowledge how much this topic is important even more!
Thanks ted-ed !
I'm learning about turbulence in geology- both in magmatism and fluvial morphology. I'm really interested in developments being made in modeling sub-laminar flow! Finding more patterns in sub-laminar flow seems to be the key to understanding more about turbulence.
Ayyy, that double pendulum footage is from a channel called Think Twice! :) You should have given him some acknowledgment so people can check out the rest of his awesome content!
Not only that but it would have been nice if he had broken down the difference between chaotic and random a bit more. I'm going to the Think Twice page to now to hear that explanation. Otherwise pretty informative video
I've submitted a request to make this video a few weeks ago and here it is. Not sure how much my request influenced the actual making of this video, but thank you very much for making it happen.
This is one of the first physics mysteries that I fell in love with, and you captured it wonderfully!
This TED-Ed animation is fantastic! The TED-Ed Team easily explains complex physics concepts.
Great job! Congratulations.
I have studied about this in my physics classes but your animations made it more interesting!! Always the best TED-ed ❤ keep it up.
Co-pilot fallen asleep....
Captain rushes in from the lavatory: Johnny! what happened?!?
Co-pilot: Errr we got sudden turbulence captain.
THE ANIMATION IS SO GOOD AND HUMOROUS TOTALLY LOVED IT!
Again, a great video from Ted-Ed with the best illustration and animation, also a very understandable naration!
Always be your fans, Ted - Ed!
1:50 Og clip is by Think Twice so please credit them
I don't think they will allow a lighter and an incense stick on the plane for you to experiment 😂😂
That isn't a plane experiment. It can be performed anywhere, with similar results.
can I just say that this animation is soo adorable and awesome?
I have giggled quite a few times during the video
Whoever did the animation on this, you made me laugh on a Monday with very little sleep and way too much work. Basically, you are a wonderful person 🧡💚
Shout out to the TED-Ed animation team... this was visually beautiful!
Kinda gave me an old Junie B. Jones Book vibe
Ted-Ed is such a unique educational channel; entertaining us with their animation and the soothing voice of the narrator. Keep it up!!
The concepts are so clearly explained, thanks
I love how you animated turbulence to explain its simple aspects.
**vogueing**
TURBULENCE!
YOU

Turbulence is not a DRINK, OR A PERSON. ITS JUST A PLANE ACCIDENT
AMBULAHNCE
YOU
BROKE
EVERYTHING!
The thing about chaos is not that it's unpredictable but that it quickly becomes less deterministic as iterations increase. This is why statistics would be useful in this scenario. Reverse engineering may not be possible, but since most adaptations are preferential, not uniform, there has to be a correlation even in chaotic systems.
its because the magnetic fields shift a tiny way that changes everything
I love the animation and narration of this video
Okay the honey, water, and ice is forgivable simply because how gorgeous the animation was done and appreciate laying the ambient sound on being on the plane nicely done.
1:46 this is from Think Twice's channel!
1:46 did you really steal this from Think Twice and gave no credit?
Very clear and nice explanation plus very hilarious graphics i love it
Thank you!! Very nice video!!
Yes, I guess some member of Ted ed team was on that plane and came up with the topic
Ted-ed
Thanks for this video as it was very informative on one of the most asked questions
Another simple work for simple ppl 👏👏👏👏 ty Ted ed
This is a very informative clip about PMS.
this video literally just summed up a whole chapter of turbulence
Hey, you used the Think Twice animation!
THINK TWICE before the TURBULENCE hit you
Amazing video as always..i love you Ted Ed💜❤️💜
Even if we are able to fully understand it, in the sense of what it described in this video, we’ll never be able to make meaningful predictions that we can apply to real-world problems because of the increasing difficulty in defining the real-world parameters to define the state of a system as a starting point. Truly understanding turbulence, however, is actually akin to being able to completely mathematically describe the game of life. When a system is so complex, with increasing levels of complex interaction, it’s essentially not possible for us to be able to fully describe it mathematically. It’s a level of complexity that’s beyond our capability to fathom, even with the fastest possible conceptual computing devices.
I'd like a copy of the TED ed daily please
*Oh they're right! You didn't credit Think Twice for the pendulum clip.*
Awesome vid!
Great content!
Keep up!
Hey Ted Ed You took part of think twice's vid and didnt give credit. You should give credit
This video is coincidental since Vox uploaded a video today also about planes lol :p
How do you guys select the excellent topics........this channel is addictive.
Its interesting to learn because the animation always looks so good!😂
1:48 is it just super similar or is that from think twice's video without credit
Boy this sounds interesting
Safir if u can go to my page and watch Victim
Awesome and informative video
The amazing animation blew my mind off.
Was the chaotic system animation taken from Think Twice?
Credit the pendulum graphic from 1:46 please
Loved the sarcastic animation ❤️
the best scientific channel at all : أفضل قناة علمية علي الإطلاق👍
ahhh...just in time when I try to procrastinate from writing my graduate thesis.....about turbulent flows
"Eddies," said Ford, "in the space-time continuum."
"Ah," nodded Arthur, "is he. Is he."
*I AM ALWAYS ROOTED TO THE TED ANIMATIONS AND FORGOT EVEN WHAT THE NARRATOR IS TALKING ABOUT...I LOVE YOU TED*
The more educational channels I stumble across on TH-cam the more I am able to appreciate the quality of your content when i eventually turn back to TED_Ed. Thank you for your effort!
3:14... well ice doesnt sink in water here.🤔
Lol yeah 😂
you assume it is ice but they never said it was ^^
3:09 when ice sinks in water:
WAIT THAT'S ILLEGAL!
Also sinks in honey
I was on a plane yesterday wondering about that. Thnks for the video.
I'll think a out that on my way home ;)
🤩i was searching for this from a couple of days
Sometimes I feel like I’m the only one who actually likes turbulence. Like as long as the plane isn’t violently ripping apart or dropping hundreds of feet out of the air, I’m chilling.
It’s like a mini roller coaster for me!
Who else expected this answer to be simple ?
This is interesting! I like learning more
Outstanding
1:46 Now I'm not saying you stole this, put it through a filter, and then used it in your video without giving credit, but... You stole this, put it through a filter, and then used it in your video without giving credit.

0:20 When you're so done with life
THIS IS GOLD.
Superb!
Finally something which I already knew.. Hash, now I can die in peace!
I don’t care WHY it happens ‘cause every time it does, I see my life flash before my eyes. Like, I start saying my prayers and mentally prepare myself for death.😂
Thats why i havent flown in 4 years, fear of heights lol plus turbulence. Not a good combination
Miss Ravenclaw when I feel a turbulence I go like “YEEEHAH!”
lol true
@@Obsessivemind I feel you. Im the same way but I know Im missing out
I hate it. I prepare for my death and start sweating profusely and feel so dizzy afterwards
Although Reynolds number was in our syllabus during graduation but they didn't taught us that much.
Thanks for sharing this information
Some from what I can tell from all my readings on turbulence. We have a good basis for understanding when and in part why it happens. We also can already describe some of its characteristics in depth and predict outcomes based on previous empirical data. However due to the mathematical complexity of the naiver-stokes equations and the chaotic nature of fluids. It is nearly impossible to come up with a good set of both mathematical models and ideas surrounding them. Where we can go from the initial state of the system and predict in detail the individual formations of the fluid. The only exception appears to as previously mentioned when there is already a large volume of empirical data.
1:50 why do y'all think it's okay to steal from other people's videos? just because you're verified doesn't mean you're immune to the concept of plagiarism
Ted-Ed, I have a question that I have always wondered, "Will time also collapse if everything in the universe, including the universe, stopped moving and get stopped?" Well, how will we measure the period for which it stopped without time being there, and how will the universe resume when time already collapsed?
Please show support so that my question reaches Ted-Ed team.
*WhAT HaVe YOu doNe!?!?*
@@j_d_gamer2091 What do u mean?
@@shreyanshmishra3278 He means 🤯 *I cAn't eVEn!!* 🤯
🤯 *I cAn't eVEn!!* 🤯
By "stop", do you mean loosing its kinetic energy instantaneously?
Disregarding *inertia*, I think this concept is cool.
Just a thought, will this phenomena occur when every particle in a universe suddenly reach absolute zero?
Great Animations.
This video about physics behind flying plane satisfied us so thank you thank you and also we want to know about balancing plane clearly and easy
Ice cube floats on water right? 3:08
Sometimes
He dropped with so much velocity but eventually it will float.
Water has a special property. It's density changes with temperature, it isn't proportional because sometimes it increases as the temperature increase and sometimes it decreases as the temperature increases.
Wait. Ice floats!
i hope u are kidding cause u did not pay attention to what he said if u think so :)
The animation is outstanding XD
TED Ed never stops teaching you new stuff, and that’s what I like about it: 👍🏻
our geography teacher showed us this video :)
edit 1 : thanks for 2 likess !
edit 2: thanks for 10 likes omgggg
edit 3: OMG 12 likes tyyyy
Edit 4 : WOW 14 like omgggggggg !!!
edit 4: What 15 likes omg thanks :)
edit 5 : never thought this comment will get 16 LIKES !
Edit 6: umm still no likes :(
ItsSpaceGurl am I gonna get edit: -ed?
Musicman928 yep , thanks for liking this comment !
I aways thought that turbulance was when the plane just crash into some bird or something caught in the propelar
I think i have a nice question for a video: Is TedEd ever gonna run out of topics to talk about? the amount of content you create is astounding and it seems infinite. Love what you do
This animation is on point
1:47 hey did you steal Think Twice’s animation?
1:46
They copied think twice channel animation from double oscillation video
How is his voice so calming i-
Wow
What a graeat explanation....
You've used ice cube to demonstrate viscosity at 3:08 but ice cube generally floats in water right.....
You've heard of Ed, Edd and Eddy. Now get ready for 2:20
Mujahid Syed no
@@coolguypablo6935 Well okay then. What should i do?
I was thinking that too. XD
Didn't understand a word but I really liked the soothing voice.
The guy that drew the animations of this video rocks!
