I don't have words to express myself of how Dr. Greene is a talented teacher.
You just did
Yes, but what he is teaching is wrong. See the post at the top of the comments.
What an absolute joy that we can summon at will and enjoy lectures from not just Brian Greene, but almost all of the masters of science from the comfort of home. Just a few decades ago people would have clamored to attend a lecture like this.
Really informative information to laymen
I love you Brian Greene, you are a gift to the world. May your Name be written in the Book of Life 🦁🔯👑!!!
You are one of the greatest educators of ANY generation. We can't thank you enough for your open minded yet skeptical and curious view of nature and your passion to share it with everyone for free. Carl Sagan would be proud.
No body does anything for free

Dr. Greene Absolutely amazing course. Connection between time, space, mass, energy and speed of light is very clear. Many thanks. Vijay
One of the best episodes of JRE was with brian greene. He rules.
Whenever I see this guy's lectures, I am glad I learned English.

Best lecturer ever
He had an excellent way to present physics to common folks

Mr. Green introduces and explains the basics of special relativity. Over the duration of this recording,. Mr. Green maintains great energy and enthusiasm for the whole damn lecture . He has a particular way of gesturing and motioning with his hands that, to me at least, conveys a good deal of passion and intuition regarding the topics he is holding forth on. On top of his ability to lecture, his examples are plentiful and really Mr. Green, I'm getting brief glimpses of a young Judd Hirsch peppered throughout.
The Revolution in teaching system is started !!! 🙂I am very thankful for it because it is open for everyone all over the world who have a burning desire to understand the UNIVERSE 🙏 like me!
Burning desire yes!!!
Yes, bro.
What a teacher Green is. Answers just about every common person questions that rises. He explains, then clears arising doubts and Repeat ! To call him genius is just a plain understatement.
I hope English is your second language ;)
😊
😊😊😊

Dr. Greene has an amazing ability. He can take a complex subject, and make it understandable. Thank you for creating this awesome video. I'd recommend it to anyone.
love this man, real teacher, and scientist
Beautiful presentation which demonstrates why people will always see things differently relative to where they are and what they are doing at any prospective point in time relative to someone else. Professor Greene, you are brilliant. I love your lectures 🥰
One of the best explanations on this topic. Simply Brilliant. Brilliantly Simple.
Brian greene is an amazing teacher. I love his lectures.
ive tried to listen to this video 10 times and I havent got past the first 30 minutes without falling asleep lol. I'm really pissed because it seems very interesting.
I finally get it! I'm 69 and after years of reading and watching, I finally understand (well sort of). In college I always ranked a great teacher above a genius in their respective field. Here you get both. Exhilarating.
Except he is completely wrong. See the post at the top of the comments.
So glad he is doing this! We need more science popularizers who simply enjoy the beauty of it with his passion and willingness to teach it the best he can to the average person
Amazing Dr. Greene. You have explained the mind boggling concepts in such simple terms. Kudos! I just realized that over 2 hrs had gone by. Time had slowed down for me... relativity!!!
Haha yeah right! An amazing presentation. I lost all sense of time.
Simple? Dude.
The fact that we are aware of our own shortcomings in our thought process, the reality that we know only a small fragment of what's out there is beyond incredible and really shows just how far humans have come. Greene is an incredible presenter, I could probably listen to him all day!
Brian you've given me the inspiration to learn the math and the confidence to. I have discovered my passion
That's awesome my guy, its extremely hard to stick with, but I wish you the best of luck. If in a few years time you become a great mathematician or physicist, respond back to this and lmk!
I havent watched this yet, I just found it and clicked on it. I will say I am excited to see this original video being put out by Dr Greene and World Science. Lets get creative and get the people to understand relativity. That includes me!!! Thank you.
Excellent Lectures
I know these principles inside and out and still love watching Dr. Brian Greene explain them. Edit: He’s both earned and deserves the respect of the title Dr.
The twin towers had a factor of safety = 3. They descended at 64% of 1G acceleration. Therefore the integrity of strength was only 1/9 of what it was. However much mass fell outside the footprint. Integrity of strength was only 1/20.
Thank you so much, Dr Greene. You are a brilliant teacher.
Wow. One of the best explanations I've seen on the internet.
What incredible insight Einstein had. His peers of that time must had been blown away by his ideas how the world works, after they accepted them.
They didn't accept it. He never even got the Nobel Price, for these ideas. Not even years after. There was NO acceptance at the time because people don't like to be blown away. So you may be right somehow...

When an interviewer asked Al what it was like being the smartest man in the world, he replied, "I don't know (more truthful than imaginable), you'll have to ask Tesla." They were peers, but only 1 was funded by crazy elitists who have 'engineered' our world to ONE big record low.

Thank u professor u r helping a lot of students who r interested in physics
Yes, Its so helpful.. I love physics and it's much interesting😍
Good to see someone who appreciates the material, instead of the usual dumb posters who seem to think they're cleverer than the world's greatest physicists.
This should be shown in every intro physics class in high school and college. He explains things that are so hard to wrap you head around with great visuals.
And he's still wrong.

@@ImInfluence time is constant
@@ImInfluence he is using one's perspective as if that changes reality. Your perspective is your point of view, example: if person is inside a one way mirror box and moving with a light clock - the person inside thinks they are stationary while the people outside the box KNOW the person inside the box is in motion. You wouldn't say the person inside the box isn't in motion (stationary), you would say the person inside the box INACCURATELY perceives they are stationary. So his explanation of why the light in motion would still register (as if it was stationary) is false. 👍
this is a very effective way of learning, from a great communicator, instead of a boring classroom for him to have the ability to take his time and put together a video, edit it, add effects if needed, etc, seems to make oldschool classrooms obsolete. combined with the ability to have massive q and a from students all around the world on any topic, it completely makes classic schools a dinosaurs approach.
There's so much more possible when your with students rather than screen sharing. Face to face is definitely better.
@@bigguy8586 you know, the best is, face to face, 1 student to 1 teacher ratio, but guess what, theres about 10-100 million potential students for every gifted teacher, so you know...yea
What is “boring” is relative from one student to another, eh? Or is it an absolute?
@Saving Democracy who decides “good”?
yes, kids have loved disney graphics for generations!
What a phenomenal lecture! I was familiar with much of the content but your explanations give an easy to understand prospective relative to our everyday world.

Proof Positive... that Prof. Green is the #1 Science Communicator in the field!
A superb pictorial representation of Special Relativity explained and presented by Prof. Brian Greene. I noticed some years ago that Brian had a great talent for explanation, I think he even exceeded himself here, excellent work. N.B. There is a mathematical version of the subject also.
You couldn't ask for a better ambassador of physics than Prof. Brian Greene.
Except he is completely wrong. Se the post at the top of the comments.
@@williamwalker39 I can't see it. What does it say exactly?
Nothing intelligent to say except these lectures are fantastic.
Amazing lecture 😀
Thanks for this Prof. Greene. I have learned so much from you. You share your knowledge with such generosity. Your passion for science is contagious.
Finally we have arrived. This is how high school physics should be thought. It looks all so easy. Of course it took half a century and lots of refinement before, we finally got to this entertaining tutorial and lesson.
Looks easy does it? Sure dude
He is the best !! Many thanks Dr. Greene
I've been trying to really understand this concept for years. This has been the best explanation yet.
Don't get me wrong, my brain is still wrecked... But less so!

Brilliant, started special relativity 2 weeks ago, I didn't believe everything I was reading till watching this video. Amazing🚀⌚
Thanks prof Brian .very helpful.
excellent presentation. And thanks for making it ad-free!
PS - This is a VERY good way to explain to teachers including professors at college. Great way for even professional to learn how to explain something a bit complicated in an easy way to average people and students. Exxcellent!
I loved his work on on BH's 90210.
Great lesson.. Thanks for the great analogies and visual work....A+..👍
Thankyou so much for combining whole course in one video. Our favourite Special Relativity Course😍
Amazing how Einstein knew everything he did. We are still proving his theory's to be true to this day as our technology and brains catch up to him.
Relativity is just an optical illusion. See my post at the top of the comments.
So kind for your time. 🙂
Hope WSU and Prof Greene return.
This is fantastic, but the shock I felt from him making Gracie get blown up by the grenade really sucked me in. This is a great way to keep humor in the physics discussion without breaking the flow of the video, just super!
Love learning from Brian Greene. A pure joy. Wish I had him as a professor. Some people have the gift of teaching. I do not lol
Excellent! - I've learned much about Relativity (Special and General), because his examples are so clear and understandable. I have a PhD in Space Science (Rice Univ. 1969). His (non-technical) explanations of Relativity are easy to follow and terrific! - Thanks, Brian (Wikipedia: Gerald J. Fishman)
Except he is teaching something that is completely wrong. See the post at the top of the comments.
Relativity: Lectures by Dr. Greene pass faster than other professors.

This is hands down the best lecture on Speed and Time
"That is the essence of science: ask an impertinent question, and you are on your way to a pertinent answer." From Chapter 4 'The Hidden Structure' From 'The Ascent of Man' ( 1973 ) J. Bronowski ( 1908 - 1974 )
i am not trying to be cynical. In fact, I watch your youtube shows every night. My eyes are dim because of retinopathy, but I like the way you explain things. My question is, why are we even bothering to try to find solutions to those questions that obviously cannot be answered? Like black holes, gravitons, and the smallest particles? I feel that we already know enough about the universe to be able to live in peace and hopefully be able to protect ourselves from cosmic threats. What else will we gain from knowing more about black holes which we cannot see or we cannot reach? is there even a chance that we will run into a black hole? if not, then I think we should dedicate our efforts to finding ways to achieve FTL travel and other such technologies that will help us reach the stars instead of just studying them from millions of light years away?
Bcoz ppl don’t know what really is time, TIME IS GODIF THEY BELIEVE IN GOD DER IS NO MORE SEARCHING NOMORE DOUBTING
For me I know im good bcoz der is a time that u don’t have to know GODS DOESNT wants you to know, BUT INN TIME
Awesome job breaking things down!
Dr. Greene Absolutely amazing course. Connection between time, space, mass, energy and speed of light is very clear. Many thanks. Vijay
Thank you for your courses...Talking about this wonderful period of the quantum revolution, we think of the great linear transformation..simplification through resonant systems...
I needed to take a second at 1:28:42, because I felt like my mind had just turned itself inside out.
In my life best lecture I have understood about space , time and Einstin theory
I remember when this course first came out and it had a bunch of problem sets you could complete and you could even write questions to Professor Green. He responded to one from me in a very detailed and thoughtful answer. There was a promise that they would follow up this course with a similar course on General Relativity and one of Quantum Mechanics but those never happened, sadly.
Relativity is just an optical illusion. See my post at the top of the comments. Study Galilean Relativity, Gravitoelectromagnetism, and Pilot Wave theory. These are the true theories of Relativity, Gravity, and Quantum Mechanics. They involve absolute space and time.
Hi! Great Lecture, Prof: and I am huge Fan! I am not physicist and having little confusion on light clock (CLOCK) example. You says Motion affects time, but in example it actually affects "clock". It would be great if you give a proper definition of Time, if time is depended on clock so what by just stopping a clock we are stopping time???
I Am with You, time is a human perception.
He never fails to impress !! Great lecture.
Respect where it's due... this was brilliant
9:22 your definition of speed is in accurate as one could say the fast or something goes the more conserved it is. So look at the conservation rate of the energy and it will tell you gravitational and acceleration etc. ratios to its self.
Thank you Professor Greene, for your time & energy spent n the production of this content. Conceptualizing & understanding these theories is made much easier to the layman on virtue of your efforts.

My brain always gets pretty fried when listening to space and time. Cause i immediately start thinking about what space itself really is. I do not have any problem with the presentations. The fact that it affects atomic clocks say there is no way around these effects
"Actually Officer, it was you who was speeding by as I was stationary along the highway"
yogibearra 420 Actually, sir, I was the one who was stationary, and you, along with the Earth, were rotating the wheels of my vehicle at speeds above the speed limit. Here’s your ticket. Have a good day.
The reference frame defense! I love it!
Unfortunately, you were moving wrt the highway. You would have to claim the highway and the roadside officer both buzzed by you and that you were stationary.
According to this view of the metaphysics of the universe, does the concept of "free will" of the individual or anybody, singly or collectively, make sense?
1:23:02 you could have used a circle with the origin at the radius for this. As each point moves away from above the origin, C is spread out
Best example yet of time dilation etc.
Great lecture Dr greene.

Perception is very important. It feels like a year to get to have a vacation, yet it goes by in the blink of an eye. Furthermore a trip going to a new place takes so so much slow time, presence.Any trip home SEEMS faster, yet they are the same miles.
What are the possibilities for the topology of space-time in the universe?
A note on intuition...As a INFJ, the only MBTI personality type that has proven intuition and a bit of a expert on it as I sometimes experience it, Intuition is not always from our experience, intuition more often comes from the other side. I know science doesn't want to accept the idea of this, but scientists need to read all the 1000's of NDE or Near Death Experiences and they will understand intuition better and the other side.
He makes it appear so simple! But I am still confused, If two clocks are moving relative to each other. Are both of the clocks moving slow relative to the other? And when they meet back with each other what happens when they compare their times?
According to the Time dilation formula, if velocity is less than speed of light, the time slows down, hence, subsequently to the future. If velocity is equal to speed of light, the time stops. And if velocity is more than speed of light, the time starts ticking reversely, where the clocks starts going in the past. Hence, to time travel into the past, we need to go faster than the speed of light. And that's why, it is proved that particles faster than the speed of light such as 'Tachyons', are the particles going to the past.

You guys should consider pinning a link to this channel on the main WSF channel because the algorithm doesn’t seem to be suggesting this channel even when the subject is closely related.

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city complain about the same time paradox unless it was effected by it. Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're randomly given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is!
Brian Greene explains String Theory and related fields in an efficient way. I read his book 'The Elegant Universe' and 'The Fabric of the cosmos' and I would not lie but besides being a 8th grader I understood String Theory and only Physicists like Greene can explain it in such simpler and efficient way.
Dr. Greene, fascinating stuff, and your presentation spectacularly illustrates concepts I have struggled to understand. Thank you. Respectfully, however, I think you need to check a few of your facts. Specifically that the Star Trek Enterprise goes way faster than light, and doesn’t seem to have any relative time dilation issues relative to earth. Clearly some of your math then must be wrong?😉
Brilliantly explained. Thank you so much. Shout out to George and Gracie Star Trek IV.
Star Trek spaceship has no seat belts
Which of course was itself an homage to George and Gracie Burns.
Unbelievably awesome! Can't say anything else! 🌟
3 mins and you see we are the centre of the universe afterall especially from a topology point of view
Absolutely fascinating! I have a silly question about the light clock example. Does the result (slowing time) hold if the clock is moving towards (or away from) the observer? Just curious. I can't mentally picture what that would do!
Just picture your perspective from another axis, in this case 'head on' regardless of it coming towards or away from you, it will essentially be zigzaging on another axis and from your perspective be moving up and down at the slower speed.
@@tylerjoseph3476 Thank you so much! What I'm struggling with is that in the simple light clock example, time slows down because of the additional distance traveled by light when you are an outside observer moving at a different speed. Yet, I don't see a difference in the distance traveled between an outside observer moving at a different speed when the light clock moves towards you and someone who moves with the clock. The double diagonals in the example disappear when light moves exactly toward you, so why does time slow down then? I know this is a simple didactic example, but to your point, it seems direction would also play a role in the speed of time. Wouldn't it? Thanks again!
