Your Daily Equation | Live Q&A with Brian Greene 

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.

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.

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 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!

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 Professor Greene, Peace and blessings to you and your family at this awful time of loss. Sincerely, Tom

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.

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 !!

Thank you so much for your explaination and sharing knowledges.

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.

AWESOME!!!! You are my Physics Hero Brian Greene, sorry I missed the live show.

Legand. Thank you Professor

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

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. 🙂

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! :)

Almost three hours 👌

Your an absolute legend !

Thank you

Thank you Professor, again for all youve done to promote rational thinking and exploration into science.

I love Brian Green's personality and enthusiasm. He really makes learning about science fun!

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.

Nice thumbnail, just noticed it today.

one more please, i watched almost all of them overnight

Thank you for making these subjects understandable for people like me who found maths extremely difficult from day one.

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.

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".

Sir... you are amazing!!!!

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

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

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!

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

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.

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).

so deeply sorry for your loss , may God confort you

So sorry to hear of your loss Professor Greene.

There are times, where I suspect, that Brian is pleasantly a bit stoned. KEEP IT UP!!!

My condolences for your mother passing. May your grief be an enlightening one.

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!

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!

Would be nice to do a topic on tensor! Thank you!!

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.

Hi Prof. Brian 👋 great view u have there WOW

Dear Professor Greene. How does light behave when its going through the dark matter? Is dark matter affected by gravity?

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)

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.

Ray of light 😂🌟🙏

Your answer to strong theory.

Sorry for your loss

good video

Apologies accepted Brian, from UK

🌞

Could you please explain some of the famous fundamental constants like permittivity and permeability and how the are derived?

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?

The elegant universe got me started into a deeper understanding of the universe, hooked for life, love your work, cool vid

❤️❤️❤️

Anyone else listen to MDEq at bedtime?

Discuss the bifurcation constant

Dear Professor, all my condolences for your mother passing. Wish you patience and courage through this difficult period.

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.

The equations of motion cannot be run in reverse because no-one has ever observed a caesium atom accumulate less vibrations. They can only be observed to accumulate more vibrations.

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?

Hi, prof brian! Will not you continue with this series anymore?? Kindly let me know...

What a beautiful background 😂😂

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?

Got one

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

I understand that the laws of motion will apply in reverse time. But does this altso apply when you account for relativity?

yes! yes! It’s friday and its christmas today. How do you know?

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

hi again - voice wanted to add, regarding scooping stuff out of a black hole... this ties in with only 5% "visibility" of the universe, gravity and "our understanding" the black hole is not "black", it holds many colours! you may only withdraw the colours you politely referred to as waste food lol

My sincere condolences.😞

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

I think the reason for order at the Big Bang or early phase of the universe has something to do with helium holds things together but as helium dissipates things start to fall apart -

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 ?

I'd really like to see some episodes or segments that go into philosophy and you could bring in people like David Chalmers?

Hi Brian - Do planets and stars perpetuate their species like living forms?

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 ...

lovely thooughts on Mark fioritinos work?

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

hi professor.... im considered "mentally ill" , this is relevant due to hearing "voices" which makes me schizophrenic... again... the relevance is what the voice tells me... it explained many things that i disbelieved, it drove me "insane"... then one day, i found out the voice was telling the truth about something regarding majick/magic and i couldn't ignore it no more, Instead, now i wanted to prove it was wrong on one occasion... it still isn't wrong to this day... I wish to know this as I share with you, "gravitational anomalies", for example, the rare strange places on earth where a car may "seem to defy gravity" by rolling uphill! also water poured on the floor "appears" to be going uphill against expectations! "THEY" (normal gullible folk) have been taught to believe that its an illusion, HOWEVER, I have personally been to one of these sites and will not fool myself into the blatant manipulation in order to be perceived as normal... I know people have created mini neutron stars on earth for testing, is it possible these anomalies may be to do with old unfound neutron star or something similar? I also know that gravity itself is used as a guide to determine the difference between up and down, in which case the "majority of normals win" as down would imply moving towards the strong force, even if up a hill lol! you thoughts would be appreciated much love - huge fan

@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.

Hi Brian Will the laws of physics change as the galaxy inflates

Hello Professor Greene, I would like to ask you about the Methuselah star. Is it older than the universe? If so how?

Can you talk about dark matters and how it fits into the string theory? Thank you

Haha :) The UFO at the end =)

If the language describes patterns as observed in the universe, how would you qualify it versus reality always trying to shift to chaos?

When Time slows down when something is moving . Is time trying to keep Entropy to its usual Steady Rate ? ?

2:02:30 Beam of light appears.

Why don’t you release # 24 and then tell us the problem,if we catch it?

Is this the last episode of the daily equation series? it's been 20 days.

Haha, I'm Scottish and even I find some Scottish dialects difficult.
