WSU: Space, Time, and Einstein with Brian Greene
Вставка
- Опубліковано 9 лют 2025
- Join Brian Greene, acclaimed physicist and author, on a wild ride into the mind of Albert Einstein, revealing deep aspects of the world that defy everyday experience. Using a visually rich canvas of animations, Greene leads you through all the startling conclusions of special relativity, from time travel to space warps to E = mc2. In the span of 2+ hours, this short master class will change your conception of reality.
This is a mostly non-mathematical version of the WSU Master Class “Special Relativity with Brian Greene.” • WSU: Special Relativit...

One of the best episodes of JRE was with brian greene. He rules.
please dont bring up JRE of all people on this channel. we dont need to be reminded a fascist apologist and platformer.
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 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 ;)

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.

One of the best explanations on this topic. Simply Brilliant. Brilliantly Simple.
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.
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.
He makes complex things simple and interesting
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.
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 🥰
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.
God has said in the Quran; " And they urge you to hasten the punishment. But Allah will never fail in His promise. And indeed, a day with your Lord is like a thousand years of those which you count." (Quran, surah 22; ayat 47)
@Brad Watson lmao go back to the fiction section
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.
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
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.
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.
@@terkfranks1538 ?
@@terkfranks1538How so?
@@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. 👍
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!
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
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 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 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...
Relatively 😏
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.
@@gsyamsri8122 Well gee, Prez Obama got that prize for what he was GONNA accomplish.
Maybe it's really just for bragging rights among the so-called elites.
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.
Brilliant, started special relativity 2 weeks ago, I didn't believe everything I was reading till watching this video. Amazing🚀⌚
Brian greene is an amazing teacher. I love his lectures.
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?
Relativity: Lectures by Dr. Greene pass faster than other professors.
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!
@@famposiom Why address him? He does not give a shit about you nor will he ever respond to you. Never ever
Lol😂. He is not going to respond to you!!! Lol😂
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.
Wow. One of the best explanations I've seen on the internet.
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!
Nothing intelligent to say except these lectures are fantastic.
I love you Brian Greene,
you are a gift to the world. May your Name
be written in the Book
of Life 🦁🔯👑!!!
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.
"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.
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!
Excellent Lectures
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!
@@paulmoffett1759 it's hard to grasp because he's WRONG. time doesn't pass slower.
@@terkfranks1538 are right . Refer to the proof at the top of the comments.
love this man, real teacher, and scientist
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.
.
Amazing lecture 😀
I needed to take a second at 1:28:42, because I felt like my mind had just turned itself inside out.
Thank you so much, Dr Greene. You are a brilliant teacher.
😂 He will NOT read your comment nor respond dumb ass😊
I love that I live in a time where I have access to this information!!
Proof Positive...
that Prof. Green is the #1 Science Communicator in the field!
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.
Thankyou so much for combining whole course in one video.
Our favourite Special Relativity Course😍
In my life best lecture I have understood about space , time and Einstin theory
you cannot tell me “the relativity of simultaneity” isn’t a gorgeous phrase
I have a kitten that pays no mind to whether any given video is playing, unless Brian Greene is speaking. Every time Brian Greene - and only Brian Greene - is on a screen, she walks over calmly, sits upright at attention and watches unwaveringly until another speaker comes on. I’m not sure of the science, but I can adequately confirm that it is pretty silly.
Hope WSU and Prof Greene return.
I legitimately fell asleep to another vid and i swear to god i was dreaming about all this weird science shit and woke up to find this. Pretty cool ngl thanks 😅
i fell asleep and i woke up and now im here
Respect where it's due... this was brilliant
Love Brian’s explanations
I loved his work on on BH's 90210.
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
So kind for your time. 🙂
Thanks prof Brian .very helpful.
😂
Unbelievably awesome! Can't say anything else! 🌟
NOW I UNDERSTAND WHY MY HIGHSCHOOL PHYSICS TEACHER KEPT STRESSING THAT SOMETHING WAS MEASURED AT REST IN EXAM QUESTIONS AND IN CLASS!!!
I'm as dumb as they come, but I'm sure if I had this guy as a teacher i would have done so much better
Great lesson.. Thanks for the great analogies and visual work....A+..👍
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.
I love this guy, Brian Greene. Im glad hes still around.
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.
Well: we aren’t, are we???
@@johnlawrence2757
Yes we are - gravitational waves, for instance, and GPS. Even his "biggest blunder" - the cosmological constant - may explain dark energy.
Greene is not only a very well equipped scientist but a great story teller as well. Many thanks.
Consciousness itself must be a function of motion and time.
Brian greene is a magician...he explains all the stuffs like a magic
Are you from india?
@@azadmosarof886 yup, and you?....
@@adityajha9665 I am also from India😀
Best example yet of time dilation etc.
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.

Good thing npesta put this in his playlist
Great video on relativity - very clear
He never fails to impress !! Great lecture.
Wonderful teaching
1st semester college physics in 2 hours. Bravo!
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.
Thank you. Explained time so much better than KH did.
Great lecture Dr greene.
Finally I understand the twin paradox!
I understand the question but not the answer.
We r all moving bcoz time doesn’t stop, time is not late nor ahead of time, der is a time of LOVE,PEACE,HOPE,FAITH AND HAPPINESS, pls, ITS TIME
I enjoyed watching, very informative, thanks for sharing❤️ Merry Christmas 🎄and Happy New Year
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

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
"do you have any idea how fast you were going"
Brian:
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...
a great and simple lecture
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.
Both channels are great and I subscribed to both of them; or maybe there’s another channel I don’t know about:)..
Wonderful ❣️😊😊😊❤️
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.
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.
Amaaaaaazing....That´s a great explanation!!!!!
thank you for sharing
3 mins and you see we are the centre of the universe afterall especially from a topology point of view
