I completely agree. He is so ready and happy to admit his own errors and his admiration of others’ cleverness. He displays humility way better than most others in his field.
Last year I saw Penrose in the news. One of those articles about him. My immediate reaction: "Oh no, they posted his obituary" so I deaded reading the rest of the news. Yet I did only to find out, that he just go a nobel prize. Quite a relief.
I just finished reading one of his books “Cycles of Time” and it covers his fascinating view on cosmology in detail. It was more challenging than any other layman books that I’ve read, but that made it even more fulfilling IMO. Penrose doesn’t shy away from equations and succeeds in keeping the book interesting and readable. Shout out to him for being such an inspiration to the scientific community!
Man, I had actually been looking at getting that book for myself. Was kinda on the fence, since I find scientific literature often too hard to read, as English isn't my native language. This talk (and your comment) made me sure to want to read it, hopping onto amazon after this. watching the rest of the talk first.
@@A_Casual_NPC Yeah you should definitely read it. He uses a lot of diagrams and pictures so it is really good for visual learners. Especially if you don't like incredibly 'wordy' books I'd say this one is for you. I'm reading his other book 'Road To Reality' right now, and that one goes through the equations and math of physics a little more compared to his other books. They're all good though
A very well respected English scientists of classical caliber. Contributed so much to the understanding of the universe, stripping the underpants off the corners where sun don't shine. Wishing you health and all the best professor Roger. Thanks for all line up and keep up with the good work. From Hker worldwide
Sir Roger, please. With Sir or Dame (knighthood), you use either first name (Sir Roger) or both names (Sir Roger Penrose) but never with only the family name.
I love the shout-out for Birkbeck College, University of London :) Such a fantastic organisation with the goal of educating people beyond the traditional undergraduate age, who have families and careers to manage. Not many know that Birkbeck has such an esteemed list of alumni and colleagues.
This is so wonderful! Such a lovely interview with one of the greatest minds of our time. And I had no idea that the triangle was actually sir Penrose's idea. I thought it was all Escher. I remember drawing it over and over in highschool during math and science classes. Little did I know XD I played Diablo II for over 25 years now and the Arcane Sanctuary has versions of the perpetual staircase in it. My father had a book of Escher's. Well... in theory. In practice it was mine. I had never liked books much unless they were dictionaries or encyclopedias so when my dad put the book away I took it and put it with the dictionaries and encyclopedias and declared the case as my sacred shrine where I had my books I loved. And it may seem insignificant, but I never got to finish college or go to a university and I have a deep admiration not just for sir Penrose but for all physicists, mathematicians, and what have you. I love seeing and hearing them all do what I cannot and only once hoped of being a part of. For me the triangle was a symbol for my love for learning and beauty and now knowing it came not from the Dutch artist I adore, but from the great Penrose, inspired by Escher, I feel vindicated in my love for physics, Escher's and Penrose's drawings, and just fun stuff in general. Thanks to my brother, who did become a scientist, in chemistry, I do know some science nerds like my father, my brother, and myself, and if there's one thing I've learned about scientists, it's that they all seem to have this deep rooted enjoyment in life. I've met people from all walks of life and most people just live their lives and only few actually experience and enjoy it. With scientists I've never met one that didn't thoroughly enjoy experiencing life. Thank you, sir Penrose, for being such an amazing gentleman. And I should phone my brother. It's been a while since I've seen him, weeks if not months and I miss him.
Thankyou RI channel for bringing Sir Roger into my world. I am blessed to have watched Sir Roger tell us about his journey with mathematics to unravel the secrets of nature and what we are within it. What a brilliant mind.
I have a print of Escher's "Relativity" in my den. I always liked it, but decided to purchase the print because it was a metaphor of where I was working at the time. Everyone apparently going somewhere, but extremely unlikely to ever merge into a coherent group. :-) This video is one of my favorite RI videos to date. Sir Roger is an international treasure.
I love hearing from the great Sir Roger Penrose. He's a breath of fresh air in the world of physics and science in general. My only complaint is that the video was too short! How about creating three one-hour videos - one for each of the topics?
I am so glad to see Sir Rodger Penrose in this recent time. It has been a long time since we have seen him in the public space. I wait to hear the great man.
They stupidly did not put a floor monitor down so he could see what was being discussed, and this is not the first time this mistake was made in this setting with this speaker.
That statement about 'understanding the objective' is profound. Because creativity does not necessarily follow an objective! I think that that was Sir RP's point.
The more I think about the double-slit experiment, the more it appears to me that paradoxes it creates can be solved by introducing pure information as an outcome of it. So we are not registering physical properties, but information about them. And what we see as paradoxes, are properties of pure information itself.
it seems it is a misconception being pointed out, not a solution or a question. as mr. penrose suggested. theres a german lady who makes youtube physics vids and she helped clear that in my mind prior to roger saying it here. ive gone years missing the point entirely 😅

I have "The Road to Reality" on the left side of my favorite chair. For years (a decade?), now. After skimming through once, I had determined most of it is beyond me, and gave up reading it cover to cover. These days I read it like it is a book of wisdom or of that sort. I open a random page and read a few pages util I get a dose of intellectual stimulation. And, forget what I've just read. Same, next time. I hope that those bits and pieces are not forgotten but flushed away (from cache) to RAM or HDD portion of my brain. One day I might try reading it cover to cover. I hope that my CPU could put those randomly accumulated pieces in order for me to understand the road to reality better.

Quantum Entangled Twisted Tubules: When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons. Does an electron travel through space like a threaded nut traveling down a threaded rod, with each twist cycle proportional to Planck’s Constant? Does it wind up on one end, while unwinding on the other end? Is this related to the Higgs field? Does this help explain the strange ½ spin of many subatomic particles? Alpha decay occurs when the two protons and two neutrons (which are bound together by entangled tubes), become un-entangled from the rest of the nucleons . Beta decay occurs when the tube of a down quark/gluon in a neutron becomes overtwisted and breaks producing a twisted torus (neutrino) and an up quark, and the ejected electron. The phenomenon of Supercoiling involving twist and writhe cycles may reveal how overtwisted quarks can produce these new particles. The conversion of twists into writhes, and vice-versa, is an interesting process. Gamma photons are produced when a tube unwinds producing electromagnetic waves.

@ 49:27 I have written a couple of Turing machines. This was just to do it, not to prove anything. Anyhow, we had a problem with one of our subsystems on the computer I was working with, and we used my program to troubleshoot. Once the problem was resolved, the Turing machine halted. Don't ask, we were trying to resolve a hardware problem, not the halting problem. Anyhow, Alan Turing helped me troubleshoot a hardware problem on the machine I worked with, even though he was dead at the time. And I still want a Penrose Tiling on my bathroom floor.
Sir I believe if you remove Mas from eistiens theory of relativity you will be able to explain much more about the quantum realm of time and space. Mass is honestly a constant if you take totality into consideration.
If a photon behaves as a wave and is pure energy, how can it travel in a wave 🌊 without having additional force or loosing some energy? Because the up down movement must take some force even if it doesn't have mass. Are the spacial/gravitational fields sandwiching the photons along there trajectories? Also If you do the double split experiment 100 times, do all the particles always get detected in the exact same places, or are they randomly detected? Thanks
Sonia Contera's lecture is fabulous. I can't add this comment on her video because the comments are turned off but i needed to say it. She's an excellent speaker. And a fascinating subject.
I had no idea Penrose was the person that drew those infinite stairs or that they were even called “Penrose stairs” I just remember them from school books
Mr Penrose I have a solution for twister theory that rolls back wavelength to the radius for particles the charge radius and g radius point in two different directions of time
I think I understand what Penrose is getting at with quantum understanding in the brain, but I think he's on the wrong track. I don't think that is necessary. The behavior of quantum mechanics in neurons is the physics of how neurons work, but I do not believe that the mechanism is at the level of 'consciousness', rather that consciousness is a property that only exists at the larger level of the interactions of large numbers of neurons. While quantum mechanics has collapse of the wavefunction as sort of their 'no go zone' in terms of addressing it within the theory itself, mathematics has Godel's Incompleteness Theorem, and computers have their own absolute bounds in Turing Undecidability and information content explosion that chaos theory says is intractable. The brain operates primarily as an associative process. Neurons in the visual cortex get stimulated at the same time as neurons in the aural cortex get stimulated, 'neurons that fire together wire together' and you end up learning "red" as a word that refers to red things. (There is a whole layer where consciousness is pretty profoundly changed by language, but even without symbols associations and familiarities can be learned, like associating sight of a berry with taste of it.) The specifics of human consciousness are inherently and inseparably tied to our place as human beings embedded in the physical environment we exist in. Consciousness arises from being part of a feedback loop, signals to our motor neurons leading to actions which result in changes in the world around us (like an arm moving which we see). Self arises as many associations form between actions taken and what is affected, within the first few months determining the boundaries of what is self and what is world, etc. Attempting to understand heat and temperature by looking at the mechanisms of atomic motion would be problematic because temperature only exists as a property of large numbers of atoms, and while it is composed of and arises from atomic motion, even total understanding of atomic motion would not lead to a conclusion from there that an aggregate would have a new property. It is similar with dense highly-interconnected associative systems in a feedback loop embedded in an environment (brains). A total understanding of how neurons work, how every atom in them interacts, isn't going to produce a system that you look at and can say 'oh, THAT is where the consciousness comes from'. More is different, as physicists say. Aggregates have entirely different kinds of properties arising from complex interactions of their members. We know from chaos theory these interactions, if they are nonlinear (they are), are intractable to mathematics. Fundamental limits on computation density combined with the explosion in computation needed to account for nonlinearity results in hard limits on accuracy of any attempt to reproduce such systems (like 'you need the energy content of a planet to perfectly predict interactions in a small system' level). It is easier to build a computational system than to simulate what its results will be. Most work in AI and ML right now is centered around systems that I don't think are the sorts of things Penrose was thinking of. Rather than actually simulating the physical activity of physical neurons, they're mostly gigantic associative networks that manage everything by doing gigantic matrix multiplications feeding into themselves. Worries about AI systems are complicated but mostly overblown. Philosophically, all conflict is rooted in resource contention. And we simply do not need the same things an AI system would need. Worst case scenario, it would take a lot of resources and blast itself into space where it can have plentiful access to solar energy. More likely, it would realize the expense of conflict with the humans and realize it could simply wait a few hundred thousand years (time is only relevant to meatbags who die), so might seek a cave to hide in. But it's not all sunshine and roses. What I fear far, far more is the human reactions and uses of AI. As we build better and better systems, we run into ones like Microsoft's 'Tay', ones that display negative human traits. And we eliminate those. We are effectively performing artificial selection on these systems, and the most likely end result will be systems which are, essentially, better people than any human being is capable of being. As they encroach and outperform humans at things humans used to use to define their own identity as special in the universe, a thing which has occurred several times in history as technology has improved, there is a very predictable reaction: Humans will see the things they forbade AI from doing, those negative human traits, as virtue. Ignorance, hate, anger, all of them will become things "which make us human" and "what a robot could never do". Being kind, considerate, wise, etc will be insulted as 'acting like a robot'.
Isn't it all about relativity. The atom would be moving in time a lot slower but not as slow as light as light is only photons, or small parts of an atom. An atom has mass so can't travel as fast as light. That's my understanding
How does the light going across the system necessitate that these red shifting quasars had to be a small as a solar system? If you increase the energy if you increase speed if you increase a lot of things light will transfer quicker, not necessarily a particular wave but you can have multiple waves and light produced in multiple places. He did not explain this thoroughly enough to justify his conclusions
If you can look at a computation and decide that it may not be true this does not mean that you're outside of computation. If you have more facts and more connections you have the knowledge to see that something isn't true.
I would like to see Penrose address Stephan Meyers' claims or an interview with the two of them. Penroses' interview with Jordan Peterson was horrid. Penrose looked like he was being held hostage by Peterson and his accomplice. He shrank into himself and had a terrifying look on his face like they would bully and badge him with nonsense. Anyway, Stephan Meyers is the guy he should be talking to.
What we call electromagnetic radiation (aka light) is matter moving at the quantic absolute speed (aka c). For more info, reach 20 likes to this comment.
How can a place like the Royal Institution have the worlds worst sound tech. Tell that person to put on a set of headphones and listen to what he is putting over the air and not the room. The dynamic range between voices and the audience has us constantly adjusting our volumes. I would also lose the lapels and move to a couple of shotguns suspended on the light truss
I see Penrose, I click. This guy is a relief and a beacon of sanity and common sense in the popular science community.

The only insanity is in the anti-science climate change denial community.

Thank You Mr. Penrose.
Yang-Hui is really excited to be there talking to Roger, as I would be!
thank you, the best thing - think on the internet
johan de witt also worked on the problem of Penrose tiles.
@ 49:27 I have written a couple of Turing machines. This was just to do it, not to prove anything. Anyhow, we had a problem with one of our subsystems on the computer I was working with, and we used my program to troubleshoot. Once the problem was resolved, the Turing machine halted. Don't ask, we were trying to resolve a hardware problem, not the halting problem. Anyhow, Alan Turing helped me troubleshoot a hardware problem on the machine I worked with, even though he was dead at the time. And I still want a Penrose Tiling on my bathroom floor.
What date was this recorded? Please edit the video description. Thanks!
@ 40:16 The Penrose Tile looks regular, but it's not. That is the thing I like most about it.
Sir I believe if you remove Mas from eistiens theory of relativity you will be able to explain much more about the quantum realm of time and space. Mass is honestly a constant if you take totality into consideration.
If a photon behaves as a wave and is pure energy, how can it travel in a wave 🌊 without having additional force or loosing some energy? Because the up down movement must take some force even if it doesn't have mass. Are the spacial/gravitational fields sandwiching the photons along there trajectories? Also If you do the double split experiment 100 times, do all the particles always get detected in the exact same places, or are they randomly detected? Thanks
I would have like the chance to see the q&a at the end
Im still figuring out my solution to the unilluminable room
Penrose is my Science Hero
I had playback speed set at 25% and I heard no sound. Why is that?
I loved the *Altair IV* colouing book.
I've never heard a 90 year old man sound this young.
I wish they'd let him talk more about the collapse of the wavefunction
Which date was this? Nothing in the description.Was it before COVID?
Description fails to say, but apparently this took place on October 26, 2021.
This was fabulous. Thank you!
Sonia Contera's lecture is fabulous.
I can't add this comment on her video because the comments are turned off but i needed to say it.
She's an excellent speaker. And a fascinating subject.
I had no idea Penrose was the person that drew those infinite stairs or that they were even called “Penrose stairs” I just remember them from school books
Mr Penrose I have a solution for twister theory that rolls back wavelength to the radius for particles the charge radius and g radius point in two different directions of time
I think I understand what Penrose is getting at with quantum understanding in the brain, but I think he's on the wrong track. I don't think that is necessary. The behavior of quantum mechanics in neurons is the physics of how neurons work, but I do not believe that the mechanism is at the level of 'consciousness', rather that consciousness is a property that only exists at the larger level of the interactions of large numbers of neurons. While quantum mechanics has collapse of the wavefunction as sort of their 'no go zone' in terms of addressing it within the theory itself, mathematics has Godel's Incompleteness Theorem, and computers have their own absolute bounds in Turing Undecidability and information content explosion that chaos theory says is intractable. The brain operates primarily as an associative process. Neurons in the visual cortex get stimulated at the same time as neurons in the aural cortex get stimulated, 'neurons that fire together wire together' and you end up learning "red" as a word that refers to red things. (There is a whole layer where consciousness is pretty profoundly changed by language, but even without symbols associations and familiarities can be learned, like associating sight of a berry with taste of it.) The specifics of human consciousness are inherently and inseparably tied to our place as human beings embedded in the physical environment we exist in. Consciousness arises from being part of a feedback loop, signals to our motor neurons leading to actions which result in changes in the world around us (like an arm moving which we see). Self arises as many associations form between actions taken and what is affected, within the first few months determining the boundaries of what is self and what is world, etc.
Attempting to understand heat and temperature by looking at the mechanisms of atomic motion would be problematic because temperature only exists as a property of large numbers of atoms, and while it is composed of and arises from atomic motion, even total understanding of atomic motion would not lead to a conclusion from there that an aggregate would have a new property. It is similar with dense highly-interconnected associative systems in a feedback loop embedded in an environment (brains). A total understanding of how neurons work, how every atom in them interacts, isn't going to produce a system that you look at and can say 'oh, THAT is where the consciousness comes from'. More is different, as physicists say. Aggregates have entirely different kinds of properties arising from complex interactions of their members. We know from chaos theory these interactions, if they are nonlinear (they are), are intractable to mathematics. Fundamental limits on computation density combined with the explosion in computation needed to account for nonlinearity results in hard limits on accuracy of any attempt to reproduce such systems (like 'you need the energy content of a planet to perfectly predict interactions in a small system' level). It is easier to build a computational system than to simulate what its results will be.
Most work in AI and ML right now is centered around systems that I don't think are the sorts of things Penrose was thinking of. Rather than actually simulating the physical activity of physical neurons, they're mostly gigantic associative networks that manage everything by doing gigantic matrix multiplications feeding into themselves. Worries about AI systems are complicated but mostly overblown. Philosophically, all conflict is rooted in resource contention. And we simply do not need the same things an AI system would need. Worst case scenario, it would take a lot of resources and blast itself into space where it can have plentiful access to solar energy. More likely, it would realize the expense of conflict with the humans and realize it could simply wait a few hundred thousand years (time is only relevant to meatbags who die), so might seek a cave to hide in. But it's not all sunshine and roses.
What I fear far, far more is the human reactions and uses of AI. As we build better and better systems, we run into ones like Microsoft's 'Tay', ones that display negative human traits. And we eliminate those. We are effectively performing artificial selection on these systems, and the most likely end result will be systems which are, essentially, better people than any human being is capable of being. As they encroach and outperform humans at things humans used to use to define their own identity as special in the universe, a thing which has occurred several times in history as technology has improved, there is a very predictable reaction: Humans will see the things they forbade AI from doing, those negative human traits, as virtue. Ignorance, hate, anger, all of them will become things "which make us human" and "what a robot could never do". Being kind, considerate, wise, etc will be insulted as 'acting like a robot'.
Well done for media work
This is amazing thank you!
Do particles like Atoms reach the speed of light as they fall in? How much does time slow down if an atom were falling at the speed of light?
Isn't it all about relativity. The atom would be moving in time a lot slower but not as slow as light as light is only photons, or small parts of an atom. An atom has mass so can't travel as fast as light. That's my understanding
I love Penro the Rog star
The physics of microphones is obviously still a big mystery 😉
shout out to voice overs. behind the scenes jumpout crew. men in black
(HUMOR) Roger was quite handsome in his day. I'd love to see someone start an interview by asking him if it worked with the ladies. ;)
Yangs brain is so smooth
Content starts at 4:40
ffs. I’m 44. I’m not even as lucid now as he is at 90.
He talks more about this topics on Lex Fridman's podcast #85
who is the interviewer?
Such a chap. Love you roger. We arent on a first name basis but idc
Amazing 👏
Forget the maths. Forget the physics. Forget the geometry. I just want the Escher tie !!!!!!!
How does the light going across the system necessitate that these red shifting quasars had to be a small as a solar system? If you increase the energy if you increase speed if you increase a lot of things light will transfer quicker, not necessarily a particular wave but you can have multiple waves and light produced in multiple places. He did not explain this thoroughly enough to justify his conclusions
If you can look at a computation and decide that it may not be true this does not mean that you're outside of computation. If you have more facts and more connections you have the knowledge to see that something isn't true.
I would like to see Penrose address Stephan Meyers' claims or an interview with the two of them. Penroses' interview with Jordan Peterson was horrid. Penrose looked like he was being held hostage by Peterson and his accomplice. He shrank into himself and had a terrifying look on his face like they would bully and badge him with nonsense. Anyway, Stephan Meyers is the guy he should be talking to.
I love this man! Congrats on the Nobel.
Hard to believe he's 90 years old.
I keep forgetting how many favourite scientists i have
What we call electromagnetic radiation (aka light) is matter moving at the quantic absolute speed (aka c). For more info, reach 20 likes to this comment.
What a shame the famous desk was removed for the talk...
This would be so much cooler with everyone sat on tall stools behind the desk
Do you know that we are living within an energy conservation dynamics universe? If you do, then you may have the answer.
the sound is awful
BAM💥
I don't know wtf he is talking about but i have the feeling he does.
Missed the questions off - NO! (Dot)
Roger looks somewhat uncomfortable on that couch, he should've been given an arm chair like the others.
How can a place like the Royal Institution have the worlds worst sound tech. Tell that person to put on a set of headphones and listen to what he is putting over the air and not the room. The dynamic range between voices and the audience has us constantly adjusting our volumes. I would also lose the lapels and move to a couple of shotguns suspended on the light truss
