WSU: Space, Time, and Einstein with Brian Greene

[@variable7833]

One of the best episodes of JRE was with brian greene. He rules.

[@Petey0707]

please dont bring up JRE of all people on this channel. we dont need to be reminded a fascist apologist and platformer.

[@lemmelovu]

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.

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.

[@harleygerken747]

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 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!

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.

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. 👍

Does somebody Knows a class video from him explaining in deep detail how gravity affect time?

[@dankuchar6821]

One way of looking at it is the gravity makes time go slower. I'm more correct way of looking at it is that mass causes time to slow down, the effect of that is what we call gravity. So actually the slowing of time is the cause of gravity not the other way around. But it just depends on the model you're using in the way you're talking about it. It's very difficult to do without getting into the mathematics. I have not found a perfect analogy yet. And the math is more advanced than most people are familiar with. I wish I had a better answer for you

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!

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".

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?

[@ariiuna1]

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!

[@tylerjoseph3476]

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.

[@ariiuna1]

@@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!

The George and Gracie light speed visual is incorrect - we have NEVER mearured the speed of light in one direction!

[@nabilj45]

I have a dumb question. Lets say we move downward every time the light hits the bottom mirror but then stop moving just before the light hits the top mirror. We do this for a very long time. Does this mean we were both in motion and time moved twice as fast instead of slowing down? If we had a person next to us traveling the same distance but with constant speed, we would have covered the same distance but be twice as old.

[@weeyooo]

If time goes slower when you move through space, as some of it is diverted into motion, does that mean that time is a form of energy?

[@EarlLedden]

Time is the medium through which energy and mass adjust so as not to butt up against the speed of light.

[@djbeeawesome]

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.

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

[@robsapplianceplus6071]

So how about this? In your example of perspective where you are observing someone traveling near the speed of light, and the theory that time slows down for that observed person with respect to the observer...., what if there was a string or rope attached between the observer and the observed? Does the end of the string or rope attached to the observed age slower than the other end attached to the observer??

[@nozack5612]

So in the light clock example, the 'moving clock' is perceived to be counting time/ticks slower than the stationary clock. But conversely, the other frame is just as valid so from the perspective of the observer with the 'moving clock', it is that clock which is operating normally and the 'stationary clock' is running slower by the same ratio: sqrt(1-v^2/c^2). Just another version of the twin paradox: which observer is actually aging more slowly?

[@anononetwofour7794]

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.
