Dear Professor Greene,
I'm sorry to hear about your mother passing. Can't imagine what it feels to have an amazingly precious person that unconditional believes in you your whole life taken away. Just know, you are in our thoughts, and we're all here for you and your family. Heart and courage professor.

I love these sessions with Brian Greene. I wish they hadn't ended. His brilliance, sense of humour, and humility are refreshing.
1Q
In 1975 I completed my Ph.D. in psychology. Now, at the age of 71 I feel like I am completing a degree in physics by listening to Dr. Greene (as well as other physicists) not only in these Daily Equation episodes but in all of his talks and presentations on the internet. What a thrill it is to keep on learning in new fields! And what a joy it is to listen to Brian Greene.
I can also recommend Leonard Susskind's online classes - they are mathematically difficult but very enlightening.
Greene already covers most talk on the meta level. You may get disappointed trying to study physics, which is more or less much different at universities. There you work mostly by memorizing formulas to be successful, instead of developing contradiction-free models and later expressing them into formulas.
@@rlsfrny thanks for sharing.
@Evan Laughlin I'm not sure what you mean (unless you do not consider psychology a science). I have been a university psychology professor for over 45 years and I don't regret one moment of it. I love all of the sciences.
Dear Professor Greene,
I wanted to tell you how much good impact you have on peoples lives, and how every content that you create is a treasure in it self. Thank you for everything!
My first ever comment on an internet forum, has perhaps been reserved for a moment like this. And it is simply to send my condolences to Prof. Greene at this time. You only have one mother. I am sorry for your loss. It was only through her that the world came to know you. And it was through you, that I began to understand our world. She did a really great job.
Dear Professor Greene,
I send my deepest condolences for your loss. Although it will provide little solace, I also feel compelled to express my appreciation for your work in sharing your knowledge and passion for physics and science with us. Your mother will be forever proud of the person she has shared with the world. Thank you. Sincerely, John
Dear Professor Greene,
I was very saddened to hear of your recent bereavement. Please accept my sincere condolences and deepest sympathy for your loss. You are in our thoughts.
With kindest regards,
Paul C. Conti
Dear Brian Greene, I love your books and videos. You have an amazing ability to describe things that are happening in our universe and you are one of the reasons I became interested in physics again. Thank you!
Thanks a lot professor 🙏🙏🙏
Mankind needs heroes like you .
I appreciate all your work. Thanks from the deepest of my soul.
Thank you for making the world of Physics understandable to those of us whose minds function differently and who while not comfortable with math computing still greatly appreciate its power in moving science forward.
Dear Mr.Greene. Thank you for YDE. Your generosity of spirit is evident in your teachings and attitudes. We love you .
Dear Professor Greene,
You don't know me, yet, through your work you have become a very important part of my life. So, it is with heartfelt sadness that I offer you my condolences. My thoughts and sympathy are with you and your family as you navigate this very difficult time.
Dear Professor Greene,
Peace and blessings to you and your family at this awful time of loss.
Sincerely, Tom
Mr.Brian Green speaks intelligently and clearly explains complex issues for the no so intelligent individuals like us.
Thanks Mr. Brian God bless .
Sir, my entire family is down with Covid19 and in india it’s spreading with leaps and bounds. Your lecture giving me relief at this hour of crisis! Love from India !!
Dr. Greene, So very sorry for the loss of your mother. My heart feels deeply for you and your family during this hard period of time you are going through.
Take care of yourself! Sincerely, Tracy
Hi Brian,
I am sorry to hear about your mother. My deepest condolences. I wanted to express my deep gratitude to you for doing these videos. They fill a massive gap I have had for ages where the 'usual' lectures (by your and many others) have been too high level and a proper physics course too detailed and time consuming. I am sure there are many others like me, who are not laymen but also not able or willing to study physics at a university. Yet we are fascinated by physics and want to learn as much as we can. If anything, I wish there was more math in these videos:). But they have been, nevertheless, something I eagerly await every few days. I hope you will be back doing them soon and I sincerely hope you will continue until you are done even if the whole Covid situation improves markedly.
AWESOME!!!! You are my Physics Hero Brian Greene, sorry I missed the live show.
Such a wonderful series, Brian. You have a real knack for explaining complicated phenomena. Thank you so much for taking the time to put this out here.
Thank you Professor, again for all youve done to promote rational thinking and exploration into science.
I believe that it is quite hopeful that you continue to talk, share and teach even when we can't exactly talk back. I appreciate your work and find it necessary to Thank You. 🙂
Legand. Thank you Professor
I would like to say thankyou for giving graduation students like myself ,a lot of new knowledge which gives us a way of thinking about new theories in the world of physics.
one more please, i watched almost all of them overnight
Thank you
I love Brian Green's personality and enthusiasm. He really makes learning about science fun!
Dr. Greene - This being the first time I've heard your many and varied activities, and all that at 75. Anyway, you are clearly a very good person, and all what you do is as a super individual.
parity transformed (reflection in 2D)
Your an absolute legend !
Thank you so much for your explaination and sharing knowledges.
I was listening and wondering, who is this young physicist talking to me like I am a kid, with a number of synonyms to make sure I get it, and with utmost care to present the scientifically objective world views. Then, Brian Greene! :)
Sir... you are amazing!!!!
Almost three hours 👌
Before the end of the series, would you please mention few of the best (in your opinion) non-specialistic books on modern/contemporary physics? Perhaps books covering a large spectrum of opinions, ranging from your excellent books to books by authors who have different views. Thanks a lot!
Hey! I have only discovered this series recently and haven't watched any of full eps. I am planning on catching up in my free time. I wanna share something (a ridiculous question) with Brian Green, was there anything mentioned about the end of series in this ep? Is it going to end soon? It was Monday yesterday and there was no ep yesterday :(
@@aarushiraheja2466 No, there was no announcement about the end of the series. There are lots of equations left!!
My condolences for your mother passing. May your grief be an enlightening one.
Interesting!
Thank you for sharing!
I’m very sorry to hear about your mother Dr. Greene. Please make the joint videos with colleagues that you were talking about in this video. Hope you’re well
Thank you for making these subjects understandable for people like me who found maths extremely difficult from day one.
brother just read as not logged on for few weeks WE ARE PRAYING FOR YOU AND YOUR FAMILY MY MOM SAID SOMETHING THAT I FELT IN MY HEART
SON ONE DAY I WILL BE GONE ASWELL BUT I LEAVE YOU, YOUR BROTHERS AND SISTERS BEHIND TO TAKE CARE OF EACH OTHER - SO BRO AS A GLOBAL FAMILY WE ALL FEEL FOR YOUR LOSS PEACE
Finally, someone tells the laymen that
Einstein's fabric of spacetime is only a two dimensional model and you have to envision this model as a three dimensional "thing".
so deeply sorry for your loss , may God confort you
Could you please explain some of the famous fundamental constants like permittivity and permeability and how the are derived?
i was thinking about something
similar.
So sorry to hear of your loss Professor Greene.
Pls continue this series. I wanna learn from professor. Pls sir. I did not this channel when these series were going on. Pls continues them
Hi Prof. Brian 👋 great view u have there WOW
Just want to say Prof. Greene don't be disheartened by the relative lack of responses on your books and TV programs, because most audiences/readers are already familiar with the core concepts, and they generally tend to find answers themselves, plus there are just not as many deep&philosophical questions. (one of the many fans from Australia)
Nice thumbnail, just noticed it today.
Would be nice to do a topic on tensor! Thank you!!
Dear Professor Greene.
How does light behave when its going through the dark matter? Is dark matter affected by gravity?
The only thing we know about dark matter is it is making gravity, it should be called dark gravity.
Great point about how it's far more fulfilling I would have thought, to be coming up with and exploring new ideas, rather than just writing criticism of other people's ideas all the time. After all.... how often are people remembered in history for being a great critic? Also criticising all new ideas suggests that one thinks we have reached the pinnacle of understanding, which seems unrealistic... and perhaps even a little arrogant. I am not saying no one should ever criticise of course... it's just some people seem to do only that and nothing else, and they do it to an excessive degree, often as if they are experiencing offence or fear, or some sort of negative emotional response to somebody's ideas.
Hi Prof. Brian,
Greetings again from West Wales (UK). Hope you are keeping well. Thank you for another great Q & A session yesterday, and thanks especially for taking 2 of my questions.
I have a very specific, technical question please - in Friday’s Q & A (05th June), you said that you were involved in producing a new project / video about dimensions & strings, which would be best viewed using V.R. equipment. Could you please inform us again, what was the item of V.R. kit that you mentioned, as being suitable to use ?
Thanks again Prof.
Take Care & Stay Safe, Best wishes. Paul C.
Thank you Brian. I really enjoy your channel. I wish I could keep up. I haven't watched this episode, just bringing my comment forward so that you have more chance to see it. But from the other comments I hear that your mother has passed so I expect you will be quite distracted. Que sera for me. Commiserations to you. In your previous Q&A you happened to cover my two strongest mysteries one after the other, very eloquently, which exposed the way I need to approach my questions.
Universe in a black hole - I wonder how the universe got out of a black hole. If it used to be the size of an orange, how could it not be a black hole. If it was and the universe couldn't escape, then we must be in one.
General Relativity - Falling objects are at rest. If there are two objects in free fall on opposite sides of the planet, how does the earth run into them without expanding and why does it speed up as it moves toward them? How does it know when to speed up?
aaIaaaaaaaaaAAAAaaaaaaaaaaaaaII

In physics, I found an incredible leaning towards one dimensional thinking. Though I learned this type of thinking is normal, it's still hard for me to believe especially when physics has wonderful people like you Brian. String Theory is more a highway than a map, not being wrong in any way but not naming itself. Einstein explains this in his work but had a hard time toggling between his type of thinking and the normal of his peers to explain it to his peers (it is exceptionally difficult to toggle between the two but is easier with practice).
Dear Professor Greene,
Saddened to hear about your mother demise. Please accept my heartfelt condolences. May the noble soul rest in peace. More power and courage to you.
I'd love to talk about what's happening in the world, or anything else. But I have no experience with youtube and can't for the life of me figure out how to catch this live and be part of it. Y'all have fun!
Is a neutron star a star that just didn’t quite make it to being a black hole? Is a black hole just a star that got heavy enough that the gravity overcomes light or is it a different animal altogether? If a black hole eventually evaporates due to Hawking Radiation will it eventually lose enough mass to no longer be black?
Hi Paul. Yes, I believe that's right. In it's last few minutes / seconds, it will be small and with a very large discharge radiance (be very bright). Hope that helps. Paul C.
❤️❤️❤️
There are times, where I suspect, that Brian is pleasantly a bit stoned. KEEP IT UP!!!
Apologies accepted Brian, from
UK
Two questions. 1) do black holes ear dark matter? If so, will they increase size? 2) if the universe is infinite, shouldn’t the temperature be absolute zero?
I understand that the laws of motion will apply in reverse time. But does this altso apply when you account for relativity?
Hi, prof brian! Will not you continue with this series anymore?? Kindly let me know...
His mother died and you think he will bother to reply you. :{
When Time slows down when something is moving . Is time trying to keep Entropy to its usual Steady Rate ? ?
No. Entropy doesn’t have a steady rate.
Hi Brian - Do planets and stars perpetuate their species like living forms?
@53:31: you've reached the conclusion that time traveling backwards means cause equals effect, but as you've said, complex things CAN happen backwards, so which is it? Chemical and biological evolution say that complex systems can emerge from simple ones. Sorry for taking your time, love this series, hoping you answer, I'm a lifelong fan of this.
Dear Professor Greene
If the fabric of space time is devided into spacetime local particles in the size of Plancks length. I expect that between them there is an extra non local grid like dimension responsible for the non local quantum behavior ( e.g entanglement ).
What do you think?
Thanks , Eran Sinbar
Your answer to strong theory.
As we know a particle will move freely in space on a rectilinear trajectory so there is now drag if it will maintain the same velocity. The drag comes when the particle encounter a force or a field that changes trajectory or accelerates . So how this can be explained by Higgs boson molasses ?
Dear Dr. Greene, I am so very sorry to hear about your loss. Based on what we know about your work, your mother gave you tremendous genes, raised you to be a very successful scientist and educator, and therefore gave millions like me the joy of learning about science and physics by a master, not to mention your scientific work that has helped move string theory forward. How wonderful for her and you to impact humanity so very positively in such needed areas! Wishing health, happiness and prosperity for you and your family!
So if the W+ and W- are there own antiparticles ( by the inverse charge per half-spin) as a preposition, then as the centre of mass is not then centre of charge the rotary pair will contribute to the Bohr magneton and that anomaly increasing with energy (by virtual particle W production). Discuss ...
Hello Professor Greene, I would like to ask you about the Methuselah star. Is it older than the universe? If so how?
If the language describes patterns as observed in the universe, how would you qualify it versus reality always trying to shift to chaos?
My sincere condolences.😞
Iv got a very long question and was really hoping you can help.
We always mention these amazing minds throughout history like Newton Maxwell Einstein etc that where leaps and bounds ahead of everyone and push our knowledge further. My question has a few questions in it. Like, when do you think the next big mind will push use forward again? Do you think they already exist but will only find out in the future?maybe we won't see another mind jump us forward again as maybe there are no new big physics questions left? or we have to wait for technology to catch up to prove these theory's correct? Or maybe we now have lots of these magnificent brains in our current mix and it's hard for someone to stand out? Do you think maybe the next Einstein will be in a diffrent filled like technology that pushed are knowledge further?
I would love you to do a piece on this and have your thoughts.
Thank you
Sorry for your loss
Anyone else listen to MDEq at bedtime?
Me! But I m missing MDEq so Much nowadays😭
🌞
The elegant universe got me started into a deeper understanding of the universe, hooked for life, love your work, cool vid
I'd really like to see some episodes or segments that go into philosophy and you could bring in people like David Chalmers?
Đeath Vader
🙃
Ray of light 😂🌟🙏
Discuss the bifurcation constant
good video
Is this the last episode of the daily equation series? it's been 20 days.
@ANURAG MANDAL how do you know??
Can you talk about dark matters and how it fits into the string theory? Thank you
Got one
Haha :) The UFO at the end =)
It was subtle, I didn't notice it.
I will resist skipping to the end to see. Stop it! Spoiler free zone please.
And the beam of light that prompted Brian to put it there!!😎 Way Cool... nicely played
At 2:11:49,yeah lol
Sir could you explain the Pauli’s exclusion principle
Sir just heard about your mother I hope everything will be okay as professor Hawking said everything will be fine sir
This video demonstrates just how little our best scientists know about Quantum Black Holes. I have followed Professor Brian Greene for years and love his science and many of his videos and chat sessions but sometimes, just sometimes, videos like this need a little polishing with regards to current knowledge.
Hi Brian, big Fan have learned a lot because of you. I have a few questions . I came across this mind-blowing article which claims that NASA's Antarctic Impulsive Transient Antenna has Detected a Tau-neutrino traveling not from outer space to earth but from the earth's surface to outer space which apparently implies that these particle are travelling back in time.
It's seems like a bold claim but it does come from NASA , could you please share your thoughts.
Why don’t you release # 24 and then tell us the problem,if we catch it?
Sorry about your mother, Prof Greene. I just saw a recent interview promoting your new book. You said you didn't believe that consciousness existed as quanta ,rather it's something that arises from the rubric of complex particles. If that's the case, then how do you and physicists explain the double-split-experiement? From lectures and shows I've seen, it seems as thought you're saying that the particle KNOWS when it's being observed, which would imply consciousness. Or is it that the observation instruments somehow interfere with the particle and that there is no mystery there? Any thoughts from anyone who can explain this to me? Thanks so much!
@BrianGreene - A Photon emitted from an inchoate Black Hole is overcome by subsequent accretion, slows down and reverses direction. Does that mean that this Black Hole must be somehow increasingly escaping from the entire Universe to preserve the Photon's relativistic velocity?
Or is the Speed of Light not a fundamental constant?
Really appreciate your thoughts here or please let me know if this is worthy discussion in a future live stream, so I don't miss it - Many thanks :-))
yes! yes!
It’s friday and its christmas today.
How do you know?
Proffesor, how could FRACTALS describe the expansion and layout of universe?
It's only a quantum computing # can calculating that kind of numbers and giving the data by computer if people have the first data # is fetched
UA-cam download on -all- Brians Q&A has broken audio -- lots of skips. wanted to listen in car as mp4. tried 3 operating systems to no avail. His equipment maybe ?
2:02:30 Beam of light appears.
Dear Professor, all my condolences for your mother passing. Wish you patience and courage through this difficult period.
What does everyone think about light clocks ? I've been looking at the back-catalogue of YDE and am having a real problem in understanding the logic of the light clock in YDE #2 Time Dilation in two fundamental ways :
1 The photon needs to be detected each time it reflects off a mirror to register a tick or tock-- it must reflect or be absorbed for detection-- it can not do both. We can ignore this for a thought experiment and imagine a demon registers the ticks and tocks instead, allowing the photon to reflect up and down uninterrupted, but the demon can't help with my second point even in a thought experiment :
2 Suppose the light clock is placed with mirrors horizontally as in the video.
With the clock at rest, the photon must bounce precisely vertically up and down. If it were at any angle, then it would zig-zag horizontally and eventually miss one of the mirrors. Thus the photon is always repeating the same vertical path, up and down, say at x=0 when the clock is at rest ( ie. the horizontal mirrors are centred at x=0 ) .
It follows that if the clock begins to translate, say to the right on the x-axis, then the photon will continue to repeat bouncing up and down on precisely this same path x=0 ( why would it reflect at an angle different to the precise vertical since the mirror is still horizontal, and there is no force or spacetime 'curvature' to point it or drag it toward the right x>0 of its reflection point in order to 'follow' the mirror ) .
Thus the mirror translates away from vertical path x=0 of the photon and the photon will miss the mirrors once the clock has moved such that the mirror is no longer under / above the original vertical photon path at x=0, and the photon escapes to infinity at x=0.
Another way to think of this is :
Suppose you are looking at a mirror. A photon bounces off you, then the mirror into your eye. If you jump fast sideways to the mirror just as the photon leaves the mirror, the photon will not deflect to ensure it still meets your eye but stays on its original path hence you no longer see yourself in the mirror.
What does everyone think ?
Can anyone explain why the photon would deflect to x0 just because the mirror moves ?
let's we just imagine that string theory is really true, i mean it's exist as a particle (2d particle) that made up a creature's body for being able to live in 4d universe of space
is this the last lecture in this series "your daily equation" ?
sir was going to make many more videos for this series isn't it ?
