I’m 44 years old and I thought I was reasonably informed on time… he lost me at teen!😢
You should have a format with an expert explaining a concept to experts of different fields.
I finally understand time thanks to the 9 yo girl
I kinda dumb so could u explain to me, why the Tstasioner/Tmoving equals to D/L. If velocity is distance/time, so time is equal to distance/velocity.
So if Ts = 2L/C
And Tm = 2D/C
Then shouldn't be the ratio of Ts/Tm = L/D ???
Please be kind and enlighten me, i am kinda lost in there
Explain Trigo to a High Schooler.
Meh
ohh ive waited for this for long time <3 adore Brian Greene
I'm a physics graduate. And the way we derive those formula that lead to the E=mc^2 took us a a whole 50 leaves ordinary notebook to completely finish it, well including the graphs and the like. It's just amazing that he simply illustrate it in a way that even ordinary viewers.can understand.

In order to go back in time you would have to essentially reverse the big bang. Planets are moving through space in a linear fashion. So you can leave a planet and return and it has continued it’s linear path. In order to go back in time you would have to reverse the linear path.
This video was great, I learned a lot however I'm struggling to understand the step explained at the 6:50 time stamp;
"More time on the stationary because it's longer distance on the moving clock"
If we are trying to get the ratio of Stationary time over Moving Time, why then did we use the distance D over distance L? Shouldn't we be using the distance L over D?
Can anyone please help clarify this to me?
what a truly beautiful discussion.
Realized a kid had to stand and move and the teenager needed a board a chalk.
Time is the measurement of the frequency of change
I think people, mountains, planets, galaxies, it's a minor organization of small particles – and at the particle level time doesn't exist. So it doesn't matter if the earth goes around the sun. They're just atoms and molecules moving around. Time is important to people. Elementary particles don't care about "time".
I believe that is why 18 is a year in "time" , in 5 different numbers in time we have decided what is called an ADULT! It is true and real and paradoxical to think that is why someone is called a minor. Even more difficult is that these things are not really difficult to understand so as we do basic things like ex. problem solve, we should resolve our issues as close to the truth as we can. And the TRUTH –what does that have to do with measurements, time, motion, movent, even math? I believe it has more to do with quality of life and world wars that we really can live a better life but only through problem resolution and now what psychological cycle offers us the best statistical possibility of that? Monarchy ? communism? dictatorship? democracy? because inside of the laws of physics is the ability to make these laws real, to use these =s to move in time to a better understanding and quality of life…..what if we lived in LIES – and these =s for gravity were wrong and the speed of light was wrong or the law of motion was a wrong theorem ????????? it = the IQ of the masses..scary
Bro that teen lvl discussion… what the
I'll watch this later.

😀Do read my blog
I learned a lot but the most interesting phenomenon was how people who learn about time and relativity slowly turn to a single look. This makes me believe that the person who understands time and relativity better than Einstein will eventually look more like Einstein than Albert Einstein himself!
"You would measure time the immeasurable and the measureless " Kahil Gibran.
It's too bad they didn't get into the perception of time based on the speed of the heart and other factors. Creatures with fast heart beats will regard their environments moving at slower speeds than those creatures with slower heartbeats (hummingbirds can't watch cartoons, etc.), larger creatures will typically move and react at slower periods of time than smaller creatures (human vs mosquito), and plants are so slow-moving that they're essentially exhaling during the day and inhaling at night (which brings new meaning to the Ents' argument in "The Lord of the Rings"). The addition of drugs like adrenaline can help speed the beats of the heart, allowing for heightened reflexes and the perception of a "slow-motion" effect. Video games and films, which emulate real life, have instituted "bullet time" since the late 90's ("The Matrix", "Max Payne", "Hitman", etc.) in which audience members/players will experience a time-slowing effect that gets triggered for heightened effects, and sometimes, a jarring change of pace. I would have liked the 6th Level of Difficulty: Dr. Brian Greene explaining time to a hummingbird.
this video pushed me to the valley of despair after 6:00. taught me the difference between an interested layman, a real hobbyist, a serious student of the subject and a real expert.
Dr Greene is a great example of a scientist who also knows and understands how people learn science
Well there you have it. My level of understanding of time and mathematics ends at the 9 year old’s 🤷🏾♀️
Does anybody know the title or doi of the paper they were talking about at the end?
It'll always be there? 30:53
What is 'always' !!!!?? I need to know
I did my best understanding when he taught the 9 year old. 🙂
He’s like if Bill Maher was nice
Ugh, I can't tell you how much I'm in love with this man. <3
Wondering if Mathematic at the Big Bang and the Big collapse changes.
