Roger Penrose on "The Portal" (w Eric Weinstein), Ep.
Вставка
- Опубліковано 31 тра 2024
- Sir Roger Penrose is arguably the most important living descendant of Albert Einstein’s school of geometric physics. In this episode of The Portal, we avoid the usual questions put to Roger about quantum foundations and quantum consciousness. Instead we go back to ask about the current status of his thinking on what would have been called “Unified Field Theory” before it fell out of fashion a couple of generations ago. In particular, Roger is the dean of one of the only rival schools of thought to have survived the “String Theory wars” of the 1980s-2000s. We discuss his view of this Twistor Theory and its prospects for unification. Instead of spoon feeding the audience, however, the material is presented as it might occur between colleagues in neighboring fields so that the Portal audience might glimpse something closer to scientific communication rather than made for TV performance pedagogy. We hope you enjoy our conversation with Prof. Penrose.

Script Apprentice 2625 thank you 🙏
wow! Thanks, this is so helpful.
Mad respect ✌🏼
Thank You
I can't appreciate enough, this is such a helpful comment. I wasn't been able to take notes while listening, but you did it for every listener in a much better way.
This is unbelievable. I would have never had access to this type of intellect or conversation in my life. I cannot really afford higher education. To have two people who have gained this knowledge talk about it in front of me for relatively no cost at all to me...this is amazing. I started researching things I would have never even heard about without this video. Thank you Eric and Sir Roger
The beautiful thing about quantum mechanics is that one doesn't have to understand the math in order to grasp the basic implications of the theory. Good luck with your autodidactic efforts.
@@dr.johnpaladinshow9747 thank you John!
The "higher education"? You mean College? haha it is no way the best for becoming smart but the federal government has made you think so with you and your parents tax dollars. If you dont absolutely need a degree go into the field and work your way up and you will have more money and experience than anyone who spent the equivalent in college and then jumped right in (if they even could) you also wont have indisputable debt ....thanks baby boomers
@@sumtingwong8768 I've done that. I should have written "I PREVIOUSLY couldn't afford higher education". I don't need this talk to make a living, I need it to start living.
These topics aren't exactly water-cooler conversations in the music scene, or sales organizations. So I normally do not have access to this. Typically these types of intellects are also uninterested in sales. However, Eric is interested in music, which was a bit of a common thread for me when he began talking about it in detail. His understanding of music, is....blurry, but still impressive for a non-musician. What he talks about regarding even-temperament and the harmonic series is correct though. Which isn't surprising, considering he's a brilliant mathematician.
The fact that you are here, means that you are pursuing a higher education. Keep your heart and mind in the right place, and learn on for the sake of passion and learning. You will find your flow with that path, and it will all work out!
The introduction is no fabrication, this is the only lecture I’ve seen so far with Roger getting excited and using his arms to extrapolate a point. Amazing
I'm a grad student in math studying axiomatic quantum field theory and unification, and this was one of the most quality conversations I've ever had the privilege of listening to.
If you are studying qft look at the wigner formulation of schrodinger equation.
You mean you’re studying algebraic quantum field theory in curved spacetime? That’s really really cool! :)
@@conorosirideain5512 I'm more focused on the axiomatic formulation in flat spacetime for now. Believe it or not, there's still no rigorous mathematical treatment of quantum fields that is completely justified. I think this might be related to our problems with putting gravity and quantum mechanics on a level playing field. Curving spacetime just makes that situation worse.
I'm also highly interested in interpretations of quantum mechanics and the measurement problem, which I think could also be related to the problem of why gravity and quantum mechanics clash, but that's more of an exotic physics question than a mathematical one.
@K. DV Not sure I understand your question clearly enough to answer.
I wish Eric would shut up more and listen Roger more !
Eric "you start with four degrees of freedom, rulers and protractors for measuring length and angle give rise to a derivative operator that measures the rise of a run from reference levels that don't knit together, which is measured by the curvature tensor which breaks into three pieces of which you throw Weyl curvature away, readjust the proportions of the other two and you set that equal to the amount of stuff" Weinstein
idono huaim - Ha! I had a similar thought!
I had recently heard him say this in another forum, and hearing it again did indeed create an identifying association in my mind.
I'd clearly be considered a piece of shit by Eric for not understanding all of this
That little rat always throw some "big worlds" to make money with stupid Joe Rogan followers.
@@everton1869 don't lose heart, it's just clever games to play with big grids of numbers. All just a conceptual way to dress up repeated multiplication and addition.
"Well, you might be playing the wrong game." This man is an absolute treasure to society.
USA v Britain , Baseball v Cricket or observing a sporting event as you believe you are a 'classical quantum state' , the beauty is we can't comprehend how Sir Roger's mind thinks.
In some remote part of the world there’s a 12 year old genius who’s stumbled upon this podcast and decided that his life goal will be to work out these concepts and change the way in which we understand reality. I just hope that when he’s awarded the Nobel prize he gives a shout out to Eric and his guests for being the catalyst.
That 12 year old genius could be a she. That'd be dope.
@Mtpimenta Why so mad? I think it's fine. ^^
Mtpimenta have you had a stroke?
He has won the Nobel prize! Are you from future?
I hope someone is looking into apps and games and bed time books and VR that is aimed at making some of the less intuitive idea spaces, somehow more intuitive, so perhaps some people will be able to make conceptual leaps with less friction.
Eric's flowery language vs Sir Roger's legendary humility.
Thank you both for the pleasant chat.
Here here!!
Eric acts like he's a genius, Roger IS one.
Eric is a prick
@@ConkerKing theyre both geniuses
@@jameconradi8269 haha he’s a prick because he uses technical language?? How sad.
I'm not even embarrassed to admit that half of what was discussed went completely over my head. However, this was one of the best podcasts I've ever listened to. Eric, please keep this up. Bring on more people of Sir Roger's caliber.
You understood half! Congratulations. I may have understood 2% to 3%, and not really, since I doubt I could explain that small percentage to someone else.
@@melvillecapps8339 I applaud your honesty, Melville! I have to admit my 50% was merely a figure of speech. I'm probably in the low double-digits at best!
There aren't that many. Maybe 12 or so.
So incredible to see Professor Penrose win the Nobel Prize.
One of the greatest minds.
@@maryjones5710 at his age, and knowing he had to win before death - I find it extraordinary. Incredible.
Well deserved of course
As Weinstein said Penrose honoured Nobel prize. Not the other way.
@@sdal4926To be fair, it's always the case. Nobel prize winners efforts are greater than some award.
Finally, someone interviewed Sir Roger in a proper way. Thank you!
Indeed.....
I always wanted to listen to Roger penrose discussing these topics.
Gotta say I wasn’t expecting 1:22:30 but wasn’t at all put off. This is YT after all and the interview was a delight. 😅
This is one of the most eye opening podcast episodes I’ve ever watched. In a sequence of epiphany after epiphany, large concepts are communicated in a condensed form making it easily digestable for a layman / amateur interested in physics. I feel like I finally managed to get a hold of some of the ideas and concepts I’ve seen talked about in other shows or lectures, whereas this one succeeded in translating such complex subject matter into comprehensible format. Thank you 🙏🏻
He reminds me a lot of Buckminster Fuller. Fuller's primary interest was on working out the geometry of how the world was actually put together.
"I’d learned at school that in order to make a sphere, which is what a bubble is, you employ pi, and I’d also learned that pi is an irrational number. To how many places, I wondered, did frustrated nature factor pi? And I reached the decision right at that moment that nature didn’t use pi. I said to myself, ‘I think nature has a different system, and it must be some sort of arithmetical-geometrical coördinate system, because nature has all kinds of models.’ What we experience of nature is in models, and all of nature’s models are so beautiful. It struck me that nature’s system must be a real beauty, because in chemistry we find that the associations are always in beautiful whole numbers-there are no fractions. And if nature can accomplish all those associations in beautiful whole numbers to make all her basic structures, I thought, then the system will turn out to be a coördinate system and it will be very, very simple. And I decided then, in 1917, that what I’d like to do was to find nature’s geometry.”
I've not encountered this quote. It is epic. Thank you.
@@jamescraig9045 Bucky is certainly one of my heroes. In fact I live in a geodesic dome.
@Tune In Drop Out Thanks for the quote. What is the source? Did you paraphrase? I like the insertion of "frustrated" before nature, but its not quite as I read the quote somewhere else.
I need to find the 60,000 that have watched this so far, and start a new country with them.
I have never loved a comment on social media so much.
A safe haven for rationality and logic. Free from judgment and violence
@@blackieblack Why?
I watched this and I don't think you want me in your country. My opinions are terrible.
Yes please I’m in
Very cool episode. I appreciate the fact that Eric doesn't insult everybody's intelligence, or interrupt the guest to attempt to explain something. He knows everybody's capable of doing their own research, and keeps the conversation moving forward in an extremely efficient manner. We're really getting twice the content with this format.
I love it, personally. This is the first episode of really anything I've watched more than once in years, besides music.
Except for Brett 😆
I noticed actually Penrose seemed to be the one slowing down to explain things to the audience, and his self consciousness about being on a "pop program" was clear.
@@JD.......... He dumbs it down pretty good for Rogan on occasion... I mean often ;p
But i also love how Eric DOES challenge his guests from time to time, with hard questions and counter-arguments.
Listening to this I don't know whether I'm becoming more intelligent or less sane.
We all should become a little less sane maybe we will then smell the fragrance of all
Or both at the same time ... :)
If you are its both and niether simultaneously.........the term is i believe 'quantitative superconfusion'.;-)
The latter indicates the former.
I'm cuuuuuuming
An absolute privilege to hear these two brilliant men share their knowledge in such an open and honest way.
Eric: this episode was your best episode to date. Congratulations.
The perfect mix of explaining the subjects without overly dumbing them down.
Chef's kiss!
Some truly incredible guests on this podcast - and what a gift for Eric to be their interlocutor, speaking frankly and asking the sorts of questions you won’t get on a late night show. This fills such a glaring need in the marketplace of ideas. Thank you Eric for putting this together and thank you Sir Roger Penrose for sharing your brilliant mind with the world! What an incredible time we live in.
That genius may be a 12 year old girl. Thatd be dope.
Here here
INDEED!
i wish tv would drop all these reality shows and put stuff like this on, i went to a comprehensive school in the 60's and i tell people i got the majority of my education from monty python (!) and those open university programs they put on at 2AM. bubble gum tv is all very well, but boy is it making nations that have tv DUMB.
Or a transcended. That wil be even more so
As an electrical engineering student a few years ago, I was blown away by the idea of fields and how charge and mass interact with the electromagnetic field and gravitational field, respectively. I hope that one day you and your guest(s) can talk more in depth about the difference between the gravitational field and the other fields. More quantum field theory and what the current problem of unifying the forces are.
Same
This gentleman brought warmth, wit, and wisdom to one of my favourite JRE episodes to date. Thanks for bringing another long-form conversation with him into the world!
This is the best Roger Penrose interview I've seen by a wide margin (!)
This podcast is exactly what we need. Talk about discussion that inspires learning.
Is it in the top 10s?
@@MarsLonsen tt
@@MarsLonsen Easily
Indeed. But above all it should inspire us to 'unlearn' all physics after the 70's. We need to go back to Dirac's twistor / spinor model of physics, representing the physics of winding the same tangible fieldlines that we call 'spacetime' into local twistors becoming what we call atom's. From here we get a clear picture that former 'space' material becomes the object property of 'energy' and former 'time' material becomes the object property of inertia (a.k.a.: 'inversed time'). In slightly different terms: in the subatomic world we have 'spacetime' replaced by 'energymass' where mass equals 'clocks' and energy equals 'grid' (which is why we see energy also in its spiraled grid form in the double slit experiment causing interference patterns). The (always) discrete number of windings these field lines is why we have 'quanta' in the energy and mass terms. Its not more mysterious than that! Thus duality is what Dirac and Penrose are describing via twistors/ spinors in their mathematical approximation. As for the reason we have complex numbers in the 'virtual' dual setting of energy mass continuum: This simply has to do with the dual speed notation. Anything we see moving in the spacetime setting must result in a compensating equal orthogonal movement in the energymass notation. So any object moving at extra [m/s] must also move at an extra component of [-J/kg] = [-Nm/kg = -m2/s2]. In other words i2=-1 in order to compensate. As for the entire movement formula: Replacing distance with energy and time with mass in the formula of : Space (distance)=time*speed becomes E=Mv2 or in the luciferious EM surrounding E=MC2. Its not harder than this...This is also why the term c2 appears in the Lorentz factor. So than, can we please go back to the time of Dirac and take it form there. We need to unlearn all fake physics of dark matter (does not exist) dark energy (does not exist) GW's traveling at C (they don't) string theory (unnecessary complications) etc etc. Duality of physics and twistor theory suffices as the fundamentals..
@@RWin-fp5jn ... and, just what is it, now, with this modern foepa swapping of then, for than, and, than, for then-? Then, is a time reference... Than, is a preference ... reference ...
Am an avg. Joe who was highly enlightened by this awesome interview, Eric you kept it on a layman's perspective that engaged
me so I never missed a word, indeed a miracle, you opened up a coveted treasure, took each beautiful item out, explained it's
origin, what it had been through and why it was conceived. Best I have ever experienced, new listener. Thank you.
Most physics isn't more difficult than a car mechanics grasp. Minus the maths
Thanks for not being afraid of posting this level of complexity, Eric! Onward!
Approximately 99.8% of this conversation flew over my head. I find it fascinating all the same and get a special delight knowing these 2 gents understand each other and the topic well enough to be engrossed and meaningfully discuss it. It's also amusing to know they are just talking around the math with anecdote and descriptive narrative. I pray a movement is started by your format, Eric, speak at the highest level of clarity you can share with your guest and it will raise the interest and overall understanding of the wider audience, maybe bit by bit but you don't 'talk down' to your listeners. Much respect received, appreciated, and reciprocated, Dr.s.
Started watching this video a couple years ago. Realized 5min in I needed to understand more to get it. Bought Penrose's book. Got swept up trying to understand the book but managed to finish it. Forgot about the podcast in the meantime. 2 Years later it showed up in my feed and thank you god for the algo google. Amazing podcast. Regardless of what you think of Weinstein or his TOE this is a must watch.
Love the awareness of the audience and the realization that you don’t have to repeat the expected interview questions, and that you don’t have to over simplify(we can look things up).
This talk needs links to relevant materials, books, talks, and papers to be fully appreciated .
And few years in college
@@pondopondo1497 or just reading books at home. You don't need college to learn anything.
Well you could read about complex numbers or watch YT videos... As a good start. There's a good String Theory videos and lectures as well.
YES!
This one talk could be a fantastic course if all the dominant structures were linked so that the listener could go off and task themselves with learning them more formally.
At least it would be cool if they, when talking about drawings, diagrams and equations, would show them on screen
Roger's entire manner and disposition are a balm to the senses. Could happily have him talk on end on whatever he wants!
Man this is so awesome. Thank you for getting more of this man in a long form conversation in the world. We are rapidly losing people of this caliber and need to preserve as much of their minds as we can.
As a physics this is an amazing conversation. My only complain is that Eric keep switching the conversation and not staying on point when an idea was being developed.
He's too much of a generalist isn't he, Eric. Can't be content trying to understand one thing perfectly, he wants to understand a thousand things just enough.
He likes to pattern interupt i.e Spotlight is on him
As a train pusher and a landscaper I must say I agree
@@alexandros6433 🤣🤣🤣
Most physicists can spell that word and formulate a coherent sentence
Actually crazy this man is 88 and is still so sharp. I know people in their sixties not even a third as coherent.
I know a presidential candidate 10 years younger one tenth as coherent.
That's true
Biden?
If you read this Roger, you inspired me so much with your theories of quantum mechanics and the brain. Thank you for all your work
Eric's constant practice in a technical discussion is to shift to overview in order to point out a useful connection between two subjects, formulas or forces. It always adds illumination and often entertains. He should land a program on a science channel.
Roger's telomeres are quite long.
That comes from selection pressure.
www.amazon.com/Taming-Telomeres-Thriller-R-Shapiro/dp/1503160998
That is strange, I would have thought someone at his age would have telomeres shorter than average.
Bring David Deutsh!
@@amazingatheist4751 I have to agree; although, I'd like to steel man Chris's premise and state that he meant that, originally Roger's telomeres were quite long. =)
As a Ph.D. student in complex differential geometry, this was a beautiful discussion.
what were the chances?
@@zacharygoodall282 Haha what are the chances.
Eric, your ability to use analogy to explain complex points, is appreciated. A "People's genius".
I wish my granddad was alive today he would of loved talks like this, it's quite unbelievable we get to listen in on it, thank you both
I think Penrose is the clearest thinker I am aware of today. Always a pleasure to see him more 'one on one'. Let's hope you get him back on the show soon. Lots of follow up provided in this one, so extra thanks for that.
But his ideas of consciousness us stupid
I could not agree with the direction and intention of this podcast more. I absolutely love these multi-hour, technical discussions with such a diverse group of interesting people. Quickly becoming one of my favorite programs. Thanks, Eric!
Thanks
You opening a conversation around geometric physics (and beyond) with a Leonard Cohen quote, is exactly why I love this Portal.
Roger Penrose, yeesh. Eric Weinstein isn't messing around.
way over my head ...still loved it
wow.. i agree... i kept looking at the view thinking, i want to understand this, but that's a great view.
it's a cool feeling and i will never get sick of it
2:16:55 AMEN!
I, for one very much appreciate sitting in the presence of people who can verbally demonstrate the attainable gulfs between our understandings
Or something like that. It's nice to be humbled now and again. Thank you both.
Eric always feel free to talk over our heads. That's what public discourse on science is missing. It's how we learn to talk and think about the subjects like adults. It's why I follow you; you exercise minimal dilution when you impart knowledge to us.
I agree. I'm thankful for this content. My one critique, however, would be that Eric doesn't always properly 'scaffold.' This can be done thru providing brief definitions (most blunt & least effective method), or by analogical comparison to commonly-known concepts, or more subtly (and most effectively) through use of synonymous parallelism.
If you notice, Roger Penrose does this a bit, enough to bring the listeners (including Eric) along.
Oh well. When listening to EW, I can always pause and use google/wiki to fill in the gaps.
On balance, I'm with you: I prefer high, challenging discourse to the dumbed down stuff we get from most public-facing scientists.
Cheers
I never saw Professor Penrose this excited, must be a interesting conversation.
"We're gunna make you work this morning sir." "I can understand that." ... That was such a wholesome exchange!
Yeah!
Fantastic job here Eric. Roger Penrose is one of the finest minds alive. Thank you for not asking him the same things. Thank you for asking him more advanced, real time scientific question. This has thoroughly quenched my thirst for deep intellectual conversation.

Utmost memorabilia and nostalgia! I traveled to some of Sir Rogers's lectures/ Seminars when studying at QMU 1980-1988 in UK. He is as humble and soft-spoken now as in his younger days. A real gift of intellect towards humanity! Thank you Eric for bringing this novel noble to meet so many viewers!
Ok
This man is going to turn 89 this year!, I am probably not half as sharp at 31.

his age really hits home when talking about being in dallas and john f. kennedy failed to show up.
@@guynxtdork Yeah, half as smart as Penrose is fine praise!
While on the road, The Portal has become a constant companion. Sir Roger Penrose and Eric Weinstein in conversation has been fun! Off to find some of those books...
My favorite episode so far. Very challenging. The index theorem has been a new intellectual obsession of mine, as it gives you an opportunity to peek into the Matrix itself. Isadore Singer is probably the most underrated intellectual alive right now. Also, get aThe Road to Reality, it is one of the most important book ever written.
Yes and thanks to Eric to call my attention to that incredible book !!
Incomparable host EW has the depth of knowledge for nuanced orchestration of such a guest as RP in a deep and revealing dialogue.
Best ive EVER heard, gentlemen. Thankyou both…. Perhaps revisit…. year or so? So so good…
This is amazing. Please let Mr. Penrose talk more about his insights in twistor theory if he ever comes back. One of the greatest geometers and artists of our time.
I envy him for the beauty his intellect gave him insight to.
Maybe the best complex Geometer since Felix Klein.
These last two episodes have been the best so far, keep inviting brilliant people who aren't afraid to go deep.
I am blown away and so grateful. Thank you Mr. Weinstein for the Portal which makes this level of discussion on the most important question there is both accessible and (with work) understandable enough for the non-super-technical. OMG - it felt magical just to listen to Sir Roger Penrose for that long in a relaxed setting. One in which he apparently felt safe enough while "boxed in" to reveal his belief that Twisters are foundational, and more. Felt more personal and warm and honestly human - ok to take risk and ok if wrong (or right!). I got a feel enough from this to keep following up on what I didn't understand. Thanks so much!
It’s not very often that I get to listen to an amazing conversation, while hardly understanding a word being said. Penrose is one of the most brilliant minds alive today.
AS A REGULAR HUMAN, I AM INSPIRED BY YOUR INTRODUCTION. I 'LOVE' THAT HINDSIGHT IS 2020. YOUR SHORT INTRODUCTION IS A PERFECT SYNOPSIS OF WHY WHAT MAKES US PEOPLE, PEOPLE. AS A FELLOW HUMAN, I AM GREATFUL.
Congratulations on winning the Nobel prize, Sir Roger Penrose!
Arguably the most lucid and free flowing discussion on “the portal” so far. Eric is showing off his knowledge of theoretical particle physics while Penrose humbly claims a lack of deep knowledge in particle physics.

This is the topic I wanted to listen sir Roger penrose discussing... Not some semi-pesudo scientific consciousness stuff
I got less than 10% of this, but I want to thank The Portal for giving me a sense of the geometry and other mathematical concepts used to analyze existence! Thank you for not dumbing it down! That's available elsewhere.
This is the most amazing podcost I've ever heard. Thank you so much Eric and Roger.
I love life twice as much since Eric started this show.
🙏
I thinkt this is the best interview with Penrose out there
Gosh I am so happy right now. I've been waiting patiently for you to elaborate more on Physics and the scientific community ever since your mention of the Hoff Fibration on JRE. And you rewarded my patience with over 2 hours with none other than Sir Penrose himself!? Astounding.
For the record, I don't mind at all that I may not understand every sentence or topic you discuss. Just eavesdropping on such a high-level conversation with one of the great minds of our time was a real treat.
Thank you so much Eric. I'm glad that you've mustered the courage to broadcast your opinions to the world, and I'm proud to be along for the ride.
I haven't seen the video yet (will watch now immediately), but I want to thank you Eric for having such a brilliant and my favorite scientist on your show.
Sir Roger is a Complex man
Roger sparks real interest for the imaginary.
@@TheLivirus nice 😂
This is the most incomprehensible english language conversation that I have ever listened to!
I've never see
Roger Penrose light up as much as he does during this interview.
Outstanding. What a privilege to listen to Sir Roger. I though that Eric did a fantastic job of letting the conversation go where it needed to go, whilst gently keeping it on track at the same time. No easy task to be sure.
Eric's knowledge of physics history is legendary.
He's a windbag who's never written a coherent paper. If only he'd shut up and let Penrose speak.
It's mostly that. His only job is making him seem smart
@@firstal3799 Well he is smart.
Hello Eric, I'm another Eric. I've been fascinated with physics since long before what I knew physics was. I'm currently taking integral calculus and will be moving into my bachelors program in physics next semester. I have a very limited understanding of the Einstein Field equations, and virtually none of linear algebra, however I remain fascinated by the concepts of relativity, quantum mechanics, QFT, and Unification theory. I love math and it has always been my strongest subject. I've been following your videos and I'm delighted to find someone that isn't afraid of getting into the nitty gritty details of the complexities of these subjects for fear of losing/confusing their viewership. Thank you. I might not have truly understood all of this episode, but I get the feeling that when I return to it in a few years, the sparks of information I have gained will flare into full realization of the importance of the ideas they represent. I have never had a great interest in biology or chemistry, but your discussion with your brother was absolutely captivating. This podcast is brilliant and I am floored with each new video I watch. Again, Thank you. Thank you for not patronizing me with the prechewed information that the media and universities put out for fear of confusing or boring the listener, and thereby reducing their profit margin. There have been so many times throughout my academic career where I've been on the brink of giving up my quest for knowledge due to the frustration of the constant "the answer to that question is way outside the bounds of this course, so you dont need to worry about it" mentality nearly every single one of my professors have. As I have matured, I realize that I must put in the effort to show that I am worthy of the answers by mastering the fundamentals, and that I must learn to walk within the system, for a time at least, before I can soar to the heights of my intellectual abilities. Nevertheless, it is conversations like these that really revitalize my interest and passion for understanding the reality within which I find myself, and my hopes that I might someday use that knowledge for the betterment of society and the progress of the human race.
This is amazing. I've read a few of Sir Roger P's books but admittedly I lose the thread of his arguments from time to time. It is a great help that I can stop the video and listen to certain segments over and over until I get some sort of grasp. Thank you Eric for the great work that you're doing.
Sir Roger Penrose the greatest living Briton, congratulations on your Nobel prize sir!
Great. Dragging humankind up one level each time.
Thank you Eric for interviewing Sir Roger Penrose, I just loved it.
I have only a very mediocre level of education, however I love hearing discussions about high-end, cutting edge mathematics, and theoretical physics.
Even with my low level of education I love to try to get some sort of understanding about their relationship and interplay.
Please record more of these sorts of discussions and debates.
my favorite interview with Penrose. Thank you, Eric
I have been trying to get through the The Road to Reality....for 3 years....1000+ pages. This interview really helps, but i'm still amazed. I Like Eric...he has a way of getting to the core of things and look at the core differently. Great stuff.
Eric the portal is amazing and I honestly just love listening to you talk I have bad anxiety and listening to the portal has really helped me with it and calmed me down but also has taught me so much thank you so much for what you do.
I'm just amazed we have access to these two brilliant people on youtube.
i really appreciate how Erik periodically pauses the whole thing to provide just enough background for what's being discussed
Thank you deeply for not dumbing down or simplifying or "bite-size cuts" this.
This is why we're all done with mainstream television.
We're sick of the 5 minute primetime dumbed down bollocks, distilled down to the lowest common denominator, never ever reaching ANY intelligent discussion or conclusion about ANYTHING being discussed.
That intro caveat is priceless. It's important to be patient with being lost when dealing with big topics. That's such a load off my stupidity.
So grateful for The Portal! Eric is truly educating us with his amazing eclectic guests as well as his own genius and desire for authenticity! I even love his "intro" music and wish he would allow it go to on a little longer!
I am So thankful that there's someone like you putting out these types of podcasts. Thank you 🙏💛
I basically did not understand a word they said from beginning to end. But I certainly appreciate that a podcast like this exists.
me neither (well some) but it's nice to know that the gobblygook that penrose talks actually makes sense to at least one person, and that one person knows other people that can make sense of it all too, so i can carry on having high regard for my hero (penrose).
Something something particles are different particles because topology? Something can be altered by 360 degrees like scissors caught in string?
Me neither but a little air of the associations he is making.
Whats a spinner?

i listened to this whilst playing tetris, can't say i understood everything but i 'got it' in a way i wouldn't have otherwise. beautiful conversation.
I love that you listened to us! The conversations are so much more insightful and interesting now that you're free to speak in the most true sense. No need to dumb things down we attain greater intelligence by being shown an example in long form. This is beautiful thank you Eric. Amazing show with Roger I can't wait to see whos next!
True
As a 60 yr old tradesman with a tenth grade education who was encouraged to not stay in school. I find these conversations on these theories so interesting and I am compelled to try and understand. I will have to watch this about 3 times to understand bout 20.% lol Penrose is amazing. I heard he was good but dam.
I love the intro. it perfectly encapsulates what it means to be a curious mind, always looking to be inspired. if you only listen to things you completely understand, there's nothing to learn.
That's the best description of general relativity I've ever heard.
The most beautiful one yet. Takes me back to my days as an undergrad. I almost heard you say "Let B be an open ball..."
What a glorious and magnificent program. Absolutely outstanding and so refreshing. This will be a historic episode. Thank you Eric.
Amazing - thank you. No doubt this interview with Roger will be watched for hundreds of years to come!
Absolutely phenomenal content Eric!
I am truly grateful to have access to content like this. Thank you Eric.
That whole interview was a great pleasure. Thank you for putting content like this online!!
Thanks Eric, loved the episode. Looking forward to the English version 😉
