Isn't it interesting that the most revolutionary solutions are also the simplest? It's great.

It’s so amazing how Einstein could come up with these amazing discoveries using only his thought experiments.

Think like a child where everything is possible.

Thank god he didn't tell his idea to Edison

It's unbelievable how Einstein was so passionate about physics even though he never watched any space video on KZfaq

1:20 the liftkeeper is from a time before Newton, so gravity doesn't affect him.

Einstien: i have a joke Me: ok Einstien: time Me: i don't get it Einstien: exactly

Imagination is more important than knowledge. - Albert Einstien. Acceleration and gravity are the same.

the real hero is the guy who invented the elevator before einstein's era.

The best feeling in physics is making sence of a concept through mind experiments and then applying math to a paper but when it comes to mathemtics the best feeling is when you try to approach a problem with different ways and in the end one of your stategies solve it

aftet watching this vid i m right now convainced that there are some people who were born to just put dislikes

Huge respect for sir Einstein, imagination is itself a very big tool to solve mysteries

1:55 only true genius observes dispersion of light along with this video

His idea that gravity and acceleration were the same thing was the beginning of his idea, not the end in itself. He soon builds on it and discovers that gravity is but a distortion of spacetime in the presence of matter - and the resulting field ultimately causes the acceleration.

"Acceleration and gravity are the same" Amazing how one can pull an entire theory out of a single line.

*I watch these clips just to make my IQ jump before exams.*

I feel this is misleading as it misses or does not properly emphasize a major component of why this is important: The realization that if you didn't know what is outside the elevator, based on the acceleration you couldn't tell if you're on an elevator that is stationary on the surface of a planet and gravity is pulling you down, or if you're in a rocket ship in outer space that is accelerating and you therefore feel the elevator floor pushing on you. And therefore acceleration and gravity are the "same". For example, if you were in a spaceship that was accelerating, and had a beam of light that started from one wall the elevator and ended on the opposite wall, the beam of light would curve slightly because during the time the light travelled, the elevator would accelerate and move slightly out of the way, and the beam wouldn't hit the spot on the wall that it would have if the ship wasn't accelerating. And then you realize that because acceleration and gravity behave in the same way, the same thing should happen to an elevator that is "stationary" and at rest on the surface of a planet. And from this you instantly get some clue about the fact that gravity bends light.

GENERAL THEORY OF RELATIVITY " MATTER AND ENERGY TELL SPACETIME HOW TO CURVE AND SPACETIME TELLS MATTER HOW TO MOVE"

Einsteins greatest gift was being able to take complicated, stupendous concepts and making them easy and simple to understand

That's so cool. I believe the same effect happens when your on a rollercoaster or one of those rides that spins really fast. It's quite fascinating and fun to experience.

One word for national geographic: awesome

the dude Einstein was talking was like: I have no idea what he is talking but I support him 100% percent.

No matter how many times i watch this, I get goosebumps every time!!

I have watched this video so many times, but every time I see it again I am awestruck on his imagination

I love the fact that I understood almost everything he said😂😂

"weightlessness is the concept potrayed here,its actually quite simple , we feel weightless when the acceleration due of elevator and acceleration due to gravity becomes equal"

How many times i have to cry.... With motivated, happy tears..

sometimes when you are stuck in some problem think simply may it bee silly but that was how great ideas were formed

Einstein = genius therefore he says learn from yesterday live for today hope for tommorow the important thing is not stop questioning

Clever Einstein,very genius

I really wanna experience the era where men like this were alive, where we still didn't understand how the universe worked, It was all theories, talk, experiments, math, men like einstein!

Wow i saw dispersion at 1:56.

And then elevator crashed....

Beautiful wonderful!!! I really enjoyed this please give us more: perhaps about Tesla and Newton and Galileo 💪🏻😎👌🏻👌🏻👌🏻👌🏻👌🏻

Brilliant explanation!!

It would be of immense pleasure to see genius in youtube please make it available :)

Actually, isn’t it the strong or weak force of the atoms/particles of the elevator that pushes you up if the elevator moves up, and the gravitational force that pushes you down when you stand in the elevator. So both forces may feel the same, but they don’t have the same cause.

The acting on this is just stunningly perfect 🎥😎😁👏🏻👏🏻👌🏻👌🏻👌🏻👌🏻👌🏻👌🏻

Its so fascinating to see how he used to think... He is becoming an inspiration for me now...!!

0:47 Ah here we go again

Imagination is everything 🙂

Please upload complete sequence

i broke my phone seeing this, it was like i was in his house watching him and crying with happiness!!!

Him and his hypothesis are so brilliant.

When I have a idea I could not think of an experiment When I have idea of an experiment I don't get thought related to it 🤐

This got me to science

Quite often the most simple thing we all thought very mundane, holds the brightest star of the dark sky. We like to just glanced over it, and never took a second time to look back. That's why "I should've seen it before" came.

N+ma=mg and when the string of the lift breaks...a gets equal to g I.e. a=g..N(apparent weight)=mg-ma or in this case N = m(g-g) which is weight is equal to=0 therefore we don't feel weight

He looks like sherlock Holmes in his mind palace.

Very obvious but still magnificent.

Where can I watch the full version

How to lose weight fast? My gym trainer: Diet + Workout Einstein: Travel through Lift from 20th floor to ground floor

I Like Albert Einstein forever

Where can i watch full episodes of this chapter?

The funny thing is that I stumbled upon this after studying about this very concept : non - inertial frames. 😅

"...alright then I'll stay with you professor Einstein!"

From this simple postulates of gravity and acceleration being the same, Einstein predicts that light can also be bend by gravity.

Where can I watch the full episodes of this series?

How can I watch this whole series?

I AM NOT GOING TO FORGET THIS VIDEO TILL MY DEATH. 29/11/2017 6:11 P.M

Sir Einstein is one of the greatest scientist ever!!

Is there a picture of Venizelos in the beginning

I want to see this movie , I get so obsessed to know more...

Weightlessness explained!!

einstein in a descending elevator: *builds an entire computation for a theory* me when elevator descends: mum come pick me up im skerd

Plz tell me..how to find the season 2 of this..

It is so simple and striking because everyone knows F=m•a Which have a consequence that every rigid mass object attracts every other rigid mass object with a *constant* acceleration, that's gravity

General relativity!!! ♡

He is a genius!

Imagine the actual happiness on his face

Are these clips from a movie or series? Somebody please help this looks so interesting all these different clips and trying to find out where it’s from and watch it all

Einstein was a poor student but a brilliant THINKER. This documentary on him is a message for the brilliant STUDENTS that they 'may not' be good at imagination.

Einstein = Genius 😉

Can someone tell me that where can i watch all the episodes of genius?

Is anyone know the link to watch full movie of this movie?

Einstein sounds like Freddy Mercury

THIS IS THE CHAPTER 4 OF CLASS 11 NLM

One among many examples of Einstein's thought experiment

this was not the purpose of the elevator thought but still a cool lecture on newtons thoughts on gravity

I love EINSTEIN. LOVE FROM INDIA 💖💕🇮🇳🇮🇳🇮🇳🙏🙏🙏

For every action there's an opposite equal reaction and Einstein explains it briantally.🕵👍😇✌⚛🚀🔭

what did he meant by rate at 1:22 ? because if he meant velocity than he was wrong the papers and elevator and floor were not of same velocity

Where can we watch this series?

Amazing. This is the best video I could use my resources and see. @national geographic credits to you

Real Genius always make everything praticle and they just not read science they live SCIENCE.

Imagine a genius guy before Einstein couldn't figure out this just because the elevator was not invented.

Correct me if i am wrong: Consider standing inside the elevator- You and the elevator which is retarding upwards . If it is moving upwards with acceleration g. g is not the force acting on the elevator or you. It is the resultant of all the forces acting on you. Now considering the idea of weight measurement- The normal reaction would come out to be 2mg. So I could'nt understand the idea of weightlessness here.

From where i can get full videos ?

I'm confused. wasn't the idea that gravity results in acceleration between masses already thought up well before Einsteins time by someone, whom I believe had the name Isaac Newton.

Ramanujan, the phenomenal Indian scientist did equally amazing things. Ramanujan is a legend, an icon of intelligence with utter humility.

Einstein is a theoretical physicist. He doesn't need to conduct experiments to prove something. He plays it on his creative mind and makes a little bit calculations. Science is beautiful.

Einstein explains class11 concept easily

Newtons third law - For every action there an equal and opposite reaction

I think that it was because of inertia that he felt like that. The elevator moved too fast and Einstein’s inertia made him stay where he was, which felt as if he was floating. And, when the elevator was rising, Einstein’s inertia mad him stay where he was, but he felt the floor because the floor was rising.

I have thought about the same thing when I was a kid, whenever I used to travel by plane.

Is this movie available on DVD?

I can't believe he was so excited for this imagination Here in India in class 11th we are taught about this thing as pseudo force. Alas we are not able to realise the beauty in it.

I already knew acceleration is gravity but when you study general relativity your brain will be crushed

Hey will you please tell me, the name of movie/ documentary this clip is ? I want to watch whole movie actually . Thanks Cheers

I'm sorry for my confusion, but what did people think gravity was before einstein related it to acceleration? didn't newton already explain gravity and gravitational force centuries ago?
