Thai: 
ลองคิดถึงคลื่นกันสักหน่อย
แนวคิดคลาสสิคของคลื่นคือว่า
มันเป็นการรบกวนที่เดินทางไปในตัวกลาง
การรบกวนที่เดินทางผ่านตัวกลาง
คำว่าการรบกวน เราหมายถึงอะไรและ
คำว่าตัวกลางหมายถึงอะไร?
เรายกตัวอย่างง่ายๆ ขึ้นมาได้
สมมุติว่าผมมีแอ่งน้ำตรงนี้
นั่นคือแอ่งน้ำเล็กๆ ของผม
และสมมุติว่าผมโยนก้อนหินลงในแอ่งนั้น
นี่คือหินของผม
มันตกลงไปในแอ่งน้ำนั้น
เราเคยเห็นแล้วว่ามันเกิดอะไรขึ้น
เมื่อมันลงไปในน้ำ
มันผลักน้ำนั้นลง
ผลักน้ำรอบๆ ลง
แล้วน้ำก็กลับขึ้นมา
แล้วคุณก็มีการรบกวนเดินทางไป
คุณมีการรบกวนที่เดินทางไป
วงแบบนี้ที่เริ่มแผ่ออก
จากจุดที่ผมปล่อยในแอ่ง

English: 
- [Voiceover] So let's think
a little bit about waves.
The classical notion of what a wave is,
is it's a disturbance
traveling through a medium.
Disturbance traveling through a medium.
So what do we mean by disturbance and
what do we mean by a medium?
We could come up with some
fairly simple examples.
Let's say that I have
a little puddle here.
So that's my little puddle.
And let's say I were to
drop a stone in that puddle.
So this is my stone.
It gets dropped in the puddle.
We've all seen what happens.
Right when it goes into the water,
that pushes that water down,
pushes the water around it out,
then that water comes back up.
Then you have this traveling disturbance.
You have this traveling disturbance.
These kind of rings that
start to radiate outward
from where I actually dropped the pebble.

Bulgarian: 
Сега ще поговорим
за вълните.
Класическата представа
за вълна е,
че тя е смущение,
пътуващо през една среда.
Смущение, преминаващо
през една среда.
Какво имаме предвид
под смущение
и какво имаме предвид
под среда?
Можем да измислим някои
доста лесни примери.
Да кажем, че имам
една малка локва тук.
Това е моята
малка локва.
И, да кажем, че пусна
един камък в тази локва.
Това е моят камък.
Пускам го
в локвата.
Всички сме виждали
какво се случва.
Точно когато
падне във водата,
това избутва
тази вода надолу,
избутва водата
около себе си навън,
а после тази вода
се връща обратно нагоре.
После имаш това
движещо се смущение.
Имаш това преместващо се
трептение.
Тези пръстени, които започват
да се разпространяват в кръг навън от там,

Korean: 
파동에 대해 생각해 봅시다
고전적인 의미의 파동은
매질을 통해 이동하는 움직임입니다
 
그렇다면 이 움직임과
매질은 무슨 뜻 일까요?
몇 가지 예를 들어보도록 하죠
웅덩이가 있다고 가정해봅시다
이게 제 웅덩이입니다
그 웅덩이에 돌을 떨어트린다고 생각해보죠
이건 제 돌이고요
웅덩이에 돌이 떨어졌습니다
그 다음 무슨 일이 벌어질진 뻔하죠
돌이 물에 떨어질 때
부딪치는 부분의 물은 아래쪽으로 밀려들어가고
주변의 있는 물은 바깥쪽으로 밀려나가죠
그리고 돌에 부딪친 물은 다시 올라오는
움직임이 보입니다
움직임이 보입니다
돌이 처음 떨어진 장소부터
원이 생기면서 바깥쪽으로 펴져나가는거죠

Thai: 
คุณเห็นพวกมันเคลื่อนที่ออกไปได้
คุณเห็นยอดคลื่นเหล่านี้แผ่ออก
เรากำลังพูดถึงการรบกวน
นี่คือการรบกวนนั้น
บ่อนั้นเคยราบเรียบสมบูรณ์
แต่เรารบกวนมัน
เราผลักมันลง
มันผลักน้ำออกไป
และน้ำนั้นผลักน้ำที่ใกล้กันขึ้นลง
ขึ้นลง
มันเดินทางออกจากจุด
ของการรบกวนตั้งต้นนั้น
เรามีการรบกวนนี้แผ่ไปผ่านตัวกลาง
ตัวกลางตรงนี้คืออะไร?
ตัวกลางตรงนี้คือน้ำ
การรบกวนตั้งต้นคือหิน
รบกวนน้ำนั้น
แต่แล้ว น้ำนั้นก็รบกวนน้ำรอบๆ มัน
ซึ่งรบกวนน้ำรอบๆ มันต่อ
การรบกวนนั้นเดินทางต่อผ่านตัวกลาง
เรายกตัวอย่างได้อีก
ถ้าผมเชือกยาวมากๆ และถือมันตรงนี้

English: 
You can actually see them move outwards.
You can see the crests of
those waves move outwards.
We're talking about a disturbance.
Well this is that disturbance.
The pond was completely flat,
but then we agitate it.
We pushed it down.
It pushed the water outwards.
Then that pushed the water
next to it up and down,
up and down.
It traveled outwards from the point
of that initial disturbance.
We have this disturbance
traveling through the medium.
What's the medium here?
The medium here is the water.
The initial disturbance was the rock
disturbing that water.
But then that water disturbed
the water around it,
which disturbed the water around it.
That disturbance kept
traveling through the medium.
We can give other examples of this.
If I take a really long string
and hold it right there.

Korean: 
원이 퍼져나가는걸 직접 볼 수 있습니다
파도의 물마루가 바깥쪽으로 움직이는 것 말이죠
우리는 움직임에 대해 말하고 있었죠
이것이 바로 움직임 입니다
웅덩이는 완전히 평평했는데
우리가 그 상태를 방해한거죠
웅덩이를 아래쪽으로 밀어 내렸고
물을 바깥쪽으로 밀어냈습니다
밀려나는 물은 주변에 있는 물을 또 위 아래로
움직이게 하면서 밀어냅니다
첫 움직임의 시점으로부터
바깥으로 이동한 겁니다
우리는 이 움직임이 매질을 통해
이동하는 것을 볼 수 있습니다
여기서 매질은 무엇일까요?
매질은 물입니다
그리고 첫 움직임은
그 돌이겠죠
하지만 돌의 부딪친 부분의 물은 주변에 있는
물에게 움직임을 만들었습니다
움직임은 매개체를 통해서 끊임없이 이동한거죠
또 하나의 예를 통해 보겠습니다
제가 긴 줄을 가지고

Bulgarian: 
където всъщност пуснах
камъка.
Можеш да ги видиш
да се движат навън.
Можеш да видиш гребените на тези вълни
да се движат навън.
Говорим за
едно смущение.
Това е това смущение.
Локвата беше
напълно равна,
но ние я раздвижваме.
Бутнахме я надолу.
Това избута водата навън.
После това избутва водата до себе си
нагоре и надолу,
нагоре и надолу.
Това се придвижи навън
от точката на
това начално
смущение.
Имаме това смущение,
което се движи през средата.
Каква е средата тук?
Средата тук
е водата.
Началното смущение
беше камъкът,
който смущава повърхността
на тази вода.
Но после тази вода
разбута водата около себе си,
която разбута
водата около себе си.
Това смущение продължи
да се движи през средата.
Можем да дадем
други примери за това.
Ако взема много голяма нишка
и я задържа ето тук...

Korean: 
제가 긴 줄을 가지고
여기에 매단다고 해보겠습니다
정말 긴 줄이죠
약간 느슨한 부분도 있어요
벽에 붙였습니다
손으로 이 줄을 위 아래로 움직인다고 생각하세요
왔다 갔다
무슨일이 벌어지죠?
만약에 제가 한번 움직이면
둥근 혹이
왼쪽에서 오른쪽으로 움직이겠죠
처음에는 이렇게 보일겁니다
조금 있으면 이런식으로 변하겠죠
이런 모양으로요
여기에 이런 움직임이 생길겁니다
방금 만든 둥근 혹을 파동이라고 말할 수 있습니다
오른쪽으로 움직일 겁니다
매질은 무엇일까요?
이 경우는 줄이 매질입니다
줄 말입니다
제가 이 줄을 위로 당겼을 때
무슨 일이 일어난 거죠?

English: 
That's my hand.
The string is, let's just
say, attached to something.
Let's say it's a really long string
and right now there's some slack in it.
It's attached to a wall.
Let's say that I were to start
moving my hand up and down.
So I move my hand up and down.
What's going to happen?
If I just did it once,
what I'm gonna have is this lump of string
move from the left to the right.
So that's what it's
gonna look like at first.
Then a few seconds later,
it's gonna look like this.
It's gonna look something like this.
You're gonna have this disturbance,
which is this wave, this
lump that I just generated.
It is going to move to the right.
What's the medium?
The medium in this case is the string.
It is the string.
What just happened there?
When I jerk the string up,

Thai: 
นั่นคือมือของผม
เชือกนั้น สมมุติว่า ผูกกับอะไรสักอย่าง
สมมุติว่ามันเป็นเชือกที่ยาวจริงๆ
และตอนนี้ มันผูกติด
มันผูกกับผนัง
สมมุติว่าผมเริ่มขยับมือผมขึ้นลง
ผมก็เลื่อนมือผมขึ้นลง
จะเกิดอะไรขึ้น?
ถ้าผมทำครั้งเดียว
สิ่งที่ผมจะได้คือ เชือกส่วนนี้
เคลื่อนจากซ้ายไปขวา
นั่นคือสิ่งที่ดูเหมือนว่าเกิดขึ้น
แล้วหลายวินาทีต่อมา มันจะเป็นแบบนี้
มันจะเป็นแบบนี้
คุณจะได้การรบกวนนี้
ซึ่งก็คือคลื่นนี้ ก้อนนี้ที่ผมสร้างขึ้น
มันจะเลื่อนไปทางขวา
ตัวกลางคืออะไร?
ตัวกลางในกรณีนี้คือเชือก
มันคือเชือก
เกิดอะไรขึ้นตรงนั้น?
ถ้าผมกระตุกเชือกขึ้น

Bulgarian: 
Това е ръката ми.
Да кажем, че нишката е
прикрепена към нещо.
Да кажем, че това е
много дълга нишка
и сега е отпусната.
Прикрепена е към една стена.
Да кажем, че започна
да движа ръката си нагоре-надолу.
Движа ръката си
нагоре-надолу.
Какво ще се случи?
Ако го направя веднъж,
това изпъкване на нишката
ще се придвижи отляво-надясно.
Така ще изглежда
отначало.
А няколко секунди по-късно
ще изглежда ето така.
Ще изглежда ето така.
Ще имаш това смущение,
което е тази вълна,
тази изпъкналост,
която създадох.
Тя ще се придвижи
надясно.
Каква е средата?
В този случай средата
е нишката.
Тя е нишката.
Какво се случи тук?
Когато придвижих
нишката нагоре,

Thai: 
ผมรบกวนโมเลกุลเชือกที่ติดกับมือผม
พวกมันดึงโมเลกุลเชือกที่ติดกับมัน
ดึงโมเลกุลเชือกที่ติดกับมัน
แล้วคุณก็ได้ก้อนนี้เดินทางไป
ทั้งคู่เป็นตัวอย่างของคลื่น
การรบกวนที่เดินทางผ่านตัวกลาง
ตอนนี้ผมมีสิ่งที่เดินทางผ่านตัวกลาง
ผมยกตัวอย่างอื่นได้
คลื่นเสียง
อะไรทำให้เกิดคลื่นเสียง?
คุณมีอนุภาคอากาศขนไปมา
ด้วยอัตราที่เร็วอย่างไม่น่าเชื่อ
แต่ถ้าคุณรบกวนพวกมัน
ถ้าคุณทำให้ อย่างเช่น กด
อนุภาคหลายตัวตรงนี้
อนุภาคอากาศเหล่านี้จะถูกอัดมากเป็นพิเศษ
การบีบอัดเกิดขึ้น
พวกมันถูกบีบอัดเป็นพิเศษ
แล้วพวกมันจะชนกับอนุภาคที่ติดกับพวกมัน
เหมือนเดิม คุณมีการรบกวนนี้
เดินทางผ่านตัวกลาง
ในกรณี ตัวกลางคืออากาศ
ตัวกลางคืออากาศ
ทีนี้ เราได้เจอแนวคิด

Korean: 
바로 제 손에 옆에 있는 줄의 분자들을 움직였습니다
움직임을 전달 받은 분자들은
옆에 있는 줄 분자들을 끌어당기게 되는 겁니다
결과적으로 이동하는 혹이 생길겁니다
위에 언급한 것들이 파동의 예입니다
매질을 통한 움직임이죠
매질을 바꿀 수도 있어요
다른 예를 들어볼까요
음파를 생각해 봅시다.
무엇이 음파를 만들어 낼까요?
주변에 상당히 빠른 속도로 튕기고 있는
많은 공기 입자들이 있습니다
그러나 당신이 그 입자들을 움직이게 하면
예를 들어 분자를
압축시킨다면
여기 있는 공기 분자는 크게 압축되게 됩니다
어떤 충돌이 형성되고
다시 강하게 압축되지요
압축된 분자들은 옆에 있는 분자와 부딪히고 튕길 겁니다
다시 움직임이 생기고
매질을 통해 움직이게 되겠지요
여기서 매질은 공기입니다
공기말이죠
자 이제 여러분은

English: 
I'm disturbing those string
molecules right next to my hand.
They're pulling on the
string molecules next to them
pulling on the sting
molecules next to them.
Then you have this traveling lump.
Once again, these are
both examples of waves.
Disturbances traveling through a medium.
Now I can give other through a medium.
I can give other examples.
Sound waves.
What causes sound waves?
You have a bunch of air
particles all bouncing around
at actually surprisingly fast speeds.
But if you disturb them,
if you cause something to, say, compress
a bunch of air particles right here.
These air particles get ultra-compressed.
Some type of clap happens,
so these get ultra-compressed.
Then they're gonna bounce
on the ones next to them.
Once again, you have this disturbance
traveling through the medium.
In this case, the medium is the air.
The medium is the air.
So, now that we've seen some

Bulgarian: 
смущавам тези молекули на нишката,
които са точно до ръката ми.
Те дърпат молекулите на нишката,
които са до тях,
а те от своя страна дърпат
молекулите на нишката до себе си.
После имаш тази изпъкналост,
която се движи.
Отново, това са
два примера за вълни.
Смущения, движещи се
през една среда.
Мога да кажа и още нещо
за средата.
Мога да дам
други примери.
Звукови вълни.
Какво причинява
звуковите вълни?
Имаш множество въздушни частици,
които си подскачат наоколо
с изненадващо
голяма скорост.
Но ако ги 
нарушиш,
ако накараш нещо да, да кажем,
притисне
няколко въздушни частици
ето тук...
Тези въздушни частици
биват супер притиснати.
Случва се някакъв вид
пляскане,
което кара тези да станат
много притиснати.
После ще отскочат от онези
до тях.
Отново, имаш това смущение,
което се движи през средата.
В този случай
средата е въздухът.
Средата е въздухът.

Bulgarian: 
Сега, когато сме виждали някои
класически идеи за вълни,
нека помислим за нещо
малко по-мистериозно.
Това е идеята
за светлината.
Светлината определено има
вълноподобни свойства.
Вълните светлина могат
да интеферират една с друга.
Можем да направим много
други видеа за светлината.
Ако взема една такава бариера
с два малки процепа в нея,
ако ги осветя
със светлина,
един начин да разгледаме това е,
че тези процепи са
единственото място, през което
преминава смущението,
а после това ще накара светлината
да се разпространи от
всеки от тях ето така.
Просто ще нарисувам
гребените на вълните.
Но това също
излиза оттук.
Можеш да видиш къде
двата гребена се срещат.

English: 
classical notions of waves,
let's think about something
a little bit more mysterious.
That is the notion of light.
Light definitely has wave like properties.
Wave light can interfere with each other.
We can do a whole other videos on light.
If I were to take a barrier like that
with two small slits in it.
If I were to shine some light,
one way to think about
it is these slits are
the only place where the
disturbance gets through
and then it would cause the light
to propagate from each of them like that.
Maybe I'm just drawing
the crests of the waves,
but also come out from here.
You can see where the two crests meet.

Thai: 
คลาสสิคของคลื่นแล้ว
ลองคิดถึงสิ่งที่เป็นปริศนามากขึ้นหน่อย
นั่นคือแนวคิดเรื่องแสง
แสงมีสมบัติเป็นคลื่นแน่นอน
คลื่นแสงแทรกสอดกันได้
เราทำวิดีโอเรื่องแสงอีกอันได้เลย
ถ้าผมอยากสร้างที่กั้นแบบนั้น
ที่มีสลิตสองอัน
ถ้าผมฉายแสง
วิธีคิดอย่างหนึ่งคือว่า สลิตเหล่านี้
คือจุดเดียวที่การรบกวนจะผ่าน
แล้วมันทำให้เกิดแสง
แผ่จากแต่ละรูอย่างนั้น
ผมจะวาดแค่ยอดคลื่น
แต่มันออกมาจากตรงนี้ด้วย
คุณเห็นได้ว่ายอดคลื่นสองตัวพบกันตรงไหน

Korean: 
몇 개의 파동의 고전적인 개념을 살펴 보았습니다
좀 더 신기한 것을 생각해 볼까요
빛의 개념을 생각해보지요
빛은 분명 파동과 같은 성질을 가지고 있습니다
서로 간섭할 수 있다는 특징이 있지요
빛의 간섭에 대해서는 또 다른
동영상에서 볼 수 있습니다
이렇게 생긴 장벽을 가지고
2개의 틈을 만들었습니다
한 방향으로 빛을 비추어 보면
이 슬릿이 빛의 움직임에 대한
유일한 통로임을 볼 수 있습니다
그러면 빛이 틈 사이로 들어가면서
이런 식으로 전달됩니다
단지 파동의 물마루를 그리는 것 처럼 보입니다만
이 부분으로도 나오게 됩니다
두 마루가 만나는 지점에서는

Bulgarian: 
Те конструктивно (положително)
ще се увеличат един друг.
Казваме, че интерферират
конструктивно.
Ако поставя някакъв вид
детектор тук,
ще видиш ярките точки
на светлината
и ще видиш тъмните точки
на светлината.
Светлината определено
се държи като вълна.
Просто ти показвам
един пример
за светлина, която се държи
като вълна.
Но ако това е вълна,
това означава, че трябва да е –
ако използваме
класическата си логика,
ще кажеш:
"Това означава, че тя е смущение, т.е.
периодична промяна на интензитета на електричното поле и на магнитната индукция,
движещо се в някаква среда."
Но каква е
тази среда?
Имаме светлина,
която идва от Слънцето.
Наричаме я
слънчева светлина.
Имаме светлина,
която идва от...
искам да я направя...
всъщност Слънцето ни е бяло,
обикновено го рисуваме
жълтеникаво,
но това е се получава,
защото светлината
 преминава през атмосферата.
Имаш Слънцето,
имаш Земята.
Това не е начертано
в мащаб.
Някак тази светлина
успява да ни достигне
през 93 милиона мили.

English: 
They're going to constructively
enhance each other.
They're going to constructively interfere.
If you were to put some type
of a detector right over here,
you would see the bright
points of the light
and you would see the
dark points of the light.
So light definitely behaves like a wave.
I'm just showing you even one example of
light behaving like a wave.
But if it is a wave, that
means it needs to be or
if we use our classical logic,
you would say,
well that means it's a disturbance
traveling through a medium.
But what is that medium?
We have light coming from our sun.
We call it sunlight.
We have light coming,
I keep wanting to make it a -
actually our sun is white,
we tend to draw it as a yellowish color,
but that's just because of its -
what happens is it goes
through the atmosphere.
So you have the sun, you have the earth.
This is not drawn to scale.
Somehow that light is able to reach us
over 93 million miles.

Thai: 
พวกมันจะเสริมกัน
พวกมันจะแทรกสอดกันแบบเสริม
ถ้าคุณใส่ตัววัดตรงนี้
คุณจะพบจุดแสงสว่าง
และคุณเห็นจุดแสงมืด
แสงจึงประพฤติตัวแบบคลื่นชัดเจน
ผมจะแสดงตัวอย่างอีกอันว่าแสง
ทำตัวเป็นคลื่น
ถ้ามันเป็นคลื่น มันหมายความว่า มันต้อง
ถ้าเราใช้ตรรกะแบบคลาสสิค
คุณบอกได้ว่า
มันหมายความว่า มันคือการรบกวน
ที่เดินทางผ่านตัวกลาง
แต่ตัวกลางนั้นคืออะไร?
เรามีแสงเดินทางจากดวงอาทิตย์ของเรา
เราเรียกมันว่าแสงอาทิตย์
เรามีแสงเข้ามา
ผมอยากให้มัน --
ที่จริง ดวงอาทิตย์ของเราเป็นสีขาว
เรามักวาดมันเป็นสีเหลือง
นั่นเป็นเพราะ --
สิ่งที่เกิดขึ้นคือว่า มันผ่านชั้นบรรยากาศ
คุณมีดวงอาทิตย์ คุณมีโลก
มันไม่ได้วาดตามสัดส่วนจริงนะ
แสงนั้นสามารถมาถึงเรา
ระยะเกิน 93 ล้านไมล์

Korean: 
서로가 보강되면서 간섭을 하게 됩니다
이렇게 보강 간섭을 일으키는 거죠
여기에 특별한 탐지기를 놓는다면
여러분들은 빛의 밝은 시점과
어두운 시점을 볼 수 있을겁니다
빛은 명백하게 파동처럼 행동하는거죠
저는 지금 빛이 파동이 될 수 있는 예를
맛보기만 보여준 것입니다
하지만 만약에 파동이라면
고전적인 개념을 적용할시
우리는
이것이 매질을 통한
움직임이라고 말할 수 있을겁니다
하지만 여기서 매질은 무엇일까요?
우리는 태양에서 오는 빛
태양빛이 있습니다
이 빛이 오게되고
우리가 보통 태양빛을
노란색으로 알고있지만
사실은 백색광이란 것을
짚고싶네요
이것은 사실
빛이 대기를 통과하면서 생기는 변화일 뿐입니다
여하튼 여기 태양과 지구가 있습니다
이건 정확한 비율이 아닙니다
어떻게든 이 빛은 9천 3만 마일이
넘는 거리에서 지구까지 도달합니다

Bulgarian: 
През какво преминава?
Дали това е периодична промяна,
движеща се в някаква среда?
Много дълго време хората са казвали,
че би трябвало да е.
Понеже има тези
вълноподобни свойства.
Изглежда се движи с някаква скорост,
скоростта на светлината.
Така че трябва да има среда,
в която се движи.
Хората се опитали да дефинират
каква е тази среда.
Наричали я
светоносен етер.
Нека запиша това,
понеже е забавна дума.
Това е хубаво име
за някоя банда.
Светоносен – не го спелувам правилно.
Светоносен етер.
Това е представата, че може би
дори във вакуума на Космоса
имаш това вещество,
този светоносен етер,
през който светлината преминава.

English: 
What's it going through?
Is it a disturbance
traveling through a medium?
Well, for a long time, people said,
well it must be.
It has these wave-like properties.
It seems to be traveling with a velocity,
the speed of light.
So there must be medium that
it is traveling through.
People theorize what this medium is.
They called it the luminiferous ether.
Let me write that down
cause it's a fun word.
It's a good name for a band.
Luminiferous. Lumine, no
I'm not spelling it right.
Luminiferous ether.
It was this idea that maybe,
even in the vacuum of space,
you have this substance.
This luminiferous ether that
the light is traveling through.
That it's somehow a disturbance

Thai: 
มันผ่านอะไรมา?
มันคือการรบกวนที่เดินทาง
ผ่านตัวกลางหรือเปล่า?
คนคิดว่ามันต้องใช่
เป็นเวลานาน
มันมีสมบัติเหมือนคลื่นเหล่านี้
มันดูเหมือนว่ามันเดินทางด้วยความเร็ว
อัตราเร็วแสง
มันต้องมีตัวกลางที่มันผ่าน
คนตั้งทฤษฎีว่าตัวกลางนี้คืออะไร
มันเรียกว่า ลูมินิเฟอรัส อีเธอร์
ขอผมเขียนลงไป เพราะมันเป็นคำที่ตลกดี
มันเหมาะเป็นชื่อวงดนตรี
ลูมินิเฟอรัส Lumine ไม่ ผมสะกดผิด
Luminiferous ether
มันคือแนวคิดว่า บางที 
แม้แต่ในสุญญากาศของอวกาศ
คุณมีสารนี้อยู่
ลูมินิเฟอรัส อีเธอร์ ที่แสงเดินทางผ่าน
นั่นคือการรบกวน

Korean: 
무엇을 통해서 오는거죠?
매질을 통해서 이동하는 움직임 일까요?
오랫동안 사람들은
틀림없이 그럴것이라고 말했습니다
빛은 파동 같은 특성이 있으니까요
빛은 광속으로
이동하고 있죠
그래서 여기에는 분명히 매질이 있어야 합니다
사람들은 이 매질이 무엇인가에 대한 이론을 제시했습니다
이것을 루미니페로스(빛을 내는) 에테르라고 부릅니다
재미있는 단어죠
밴드 이름으로 참 좋을 것 같아요
빛을 내는 에테르
빛을 내는 에테르
이 에테르는 진공에서도 존재한다고
믿어지는 물질이었습니다
이 물질은 빛이 통과하는 매질입니다
이것에 의해

Korean: 
빛이 움직임을 일으키는거죠
이제 다음 동영상에선 이것이 진짜 사실인지를
한번 시험해볼게요
만약 루미니스페로스 에테르가 있다면
지구는 루미니스페로스 에테르에 대하여
상대적으로 정지된 상태가
아니기 때문에
더 흥미롭다고 볼 수 있습니다
사실 지구는 태양을 중심으로 돌고 있습니다
태양은 은하계를 중심에서 돌고 있고요
지구는 절대로 루미느스페로스 에테르와
상대적으로 정지된 상태가 될 수 없는것이죠
만약 우리가 상대적으로 정지된 상태가 아니면
우리는 빛이 어떻게 행동하는지를
확인할 수 있을 것입니다
빛이 에테르 방향으로 이동하는지
아니면 빛이 에테르의 움직임의
반대방향으로 이동하는지를
상대적 운동을 따져볼 수 있습니다
우선 여기서는 이렇게 마무리를 짓겠습니다
과학의 미스터리죠
우리는 매질을 따라 움직이는 파동을
물과 공기 또한 줄로
탐구해보았습니다
하지만 빛은 어떨까요?
과연 루미니스페로스 에테르는 존재하는 걸까요?
같이 생각해 봅시다

Bulgarian: 
Че съществува някаква периодична промяна
в този светоносен етер.
В бъдещи видеа
ще проверим това.
Ще видим дали е истина,
понеже интересното е,
че ако има светоносен етер,
няма да сме неподвижни
спрямо този светоносен етер.
Всъщност обикаляме
в орбита около Слънцето.
Слънцето обикаля в орбита
около центъра на галактиката.
Няма начин да сме
неподвижни
по отношение на
този светоносен етер.
Ако не сме неподвижни
спрямо този светоносен етер,
трябва да можем да засечем
поведението на светлината.
Дали тя се движи
в посоката на етера,
или се движи срещу посоката
на сравнителното движение на етера
спрямо нас.
Както и да е,
ще приключим тук
с тази научна мистерия.
Вълни – периодична промяна,
движеща се в някаква среда.
Видяхме това по-рано
с водата, въздуха и нишката.
Ами светлината?
Има ли светоносен етер?
Тук слагаме
въпросителен знак.

English: 
in that luminiferous ether.
Now, what we're gonna do in future videos,
is we're gonna test that.
We're gonna see if
that's actually the case
because what's interesting
about if there is
a luminiferous ether,
we're not gonna be stationary relative to
that luminiferous ether.
In fact, we're orbiting around the sun.
The sun is orbiting around
the center of the galaxy.
There's no way that we're gonna be
stationary relative to
that luminiferous ether.
If we're not stationary relative to that
luminiferous ether, we should be able to
detect how light behaves.
If it's going in the direction of ether
or if it's going against the direction of
the relative movement of
the ether relative to us.
So anyway, I'll leave you there.
This mystery of science.
Waves, disturbance through a medium.
We saw that with the water,
with the air, with the string.
But what about light?
Is there a luminiferous ether?
Put a question mark there.

Thai: 
ในลูมินิเฟอรัส อีเธอร์นั้น
ทีนี้ สิ่งที่เราจะทำในวิดีโอหน้า
คือเราจะทดสอบมัน
เราจะเห็นว่ามันเป็นจริงไหม
เพราะสิ่งที่น่าสนใจคือว่า มันมี
ลูมินิเฟอรัสอีเธอร์จริงไหม
เราจะไม่อยู่นิ่งเทียบกับ
ลูมินิเฟอรัส อีเธอร์นั้น
ที่จริง เรากำลังโคจรรอบดวงอาทิตย์
ดวงอาทิตย์โคจรรอบศูนย์กลางของกาแล็กซี่
มันไม่มีทางที่เราจะ
อยู่กับที่เทียบกับลูมินิเฟอรัสอีเธอร์นั้น
ถ้าเราไม่อยู่กับที่เทียบกับ
ลูมินิเฟอรัสอีเธอร์นั้น เราควรสามารถ
วัดว่าแสงทำตัวอย่างไร
ว่ามันไปในทิศเดียวกับอีเธอร์
หรือมันต้านทิศ
การเคลื่อนที่ของอีเธอร์ วัดเทียบกับเรา
เอาล่ะ ผมจะปล่อยคุณไว้ตรงนี้
ปริศนาของวิทยาศาสตร์นี้
คลื่น คือการรบกวนผ่านตัวคลื่น
เราเห็นในน้ำ
ในอากาศ ในเส้นเชือก
แต่แสงล่ะ?
มันมีลูมินิเฟอรัสอีเธอร์ไหม?
