Smart not nerd, creative and daring, not parrot, gets deep abstract insights without losing touch with reality. In one word, genius.

What a legend.

Sir Roger is without doubt one of our finest ever national treasures - long may he and his level headedness (considering the natures of the problem domains of the issues he tackles) remain with us. :)

I first read his name in a book by Stephen Hawking, Blackholes and Baby Universes. Then I read Penrose's book Shadows of the Mind, then I got a Mammoth work by Penrose, The Road To Reality, more than 10 years on, I'm still finishing it up... It has been an extraordinary guidance... Thank you Sir Penrose.

I literally said out loud: "Wat een held", which is Dutch and translates to "What a legend", many times throughout this excellent insight into reality!

Sir Roger Penrose is as great as Feynman and Einstein. One of the GREATS.

Dr Penrose as brilliant as ever! Thanks very much for this video.

Watching this twice, listening to Sir Roger!! OMG!! having similar dislikes to a lot of current ideas as I do -- and making so much sense. And offering an interpretation that tracks beautifully with what we see all around us. Thank you very much for posting this lecture.

Just *beautiful* 🔥 tnx alot ✨

Congrats!! He seems to be a very nice man.

Brilliant! (Sir) Roger never really got on with 'Powerpoint', but he is improving his visual aids a little.

Love you Roger.

damnnnnn this is hard for the layman..not complaining...he's certainly not patronizing :p

You need fantasy (imagination) to throw a conjecture up to nature and see the result. Popper said that long ago. Be bold first; then be humble enough to correct your error. A theory demands both attributes: boldness and humbleness. There's no induction; only a conjecture and deductions. The game of science never ends (cf. The Logic of Scientific Discovery).

Well, we just need to know what energizes particles at the end / beginning of eons.

I love this dude!

19:33 Wow, EPIC tangent, and then expertly finds his way back

Living Legend

Amazing!

I love Roger Penrose❤

I've read a lot of his work, to me, he's the finest mind I've had the good fortune to encounter in my entire, longish life.

Thank you

Does he do his own illustrations. They are true art.

Proofs and Principles determine the abstract or reality of faith or fantasy.

Sir Roger Penrose brilliant brain

I tripped out on this...class! Extra dimensions ahoy!!

Thanks! Sir Roger is always entertaining. Quantum Mechanics: the theory stating that not only can Mother Nature *_not_* make up her fiddling mind, but *_also_* that, whatever she decides, she then interferes with herself! But that's neither here nor there... [rim-shot] Thanks again! Rikki Tikki.

Who is watching after he got Nobel prize in physics?

Long live the great platonist of our age.

He is legend 🥳🥳🥳...he got Nobel prize 2020....

Is it possible the particle splits into a positive and negative pair and creates a z-wave traveling in a spiral motion? This would look like a wave, with frequency and wavelength

11:35 a**(b**c) = a**(c**b) = a**(b*c)..... so actually it largely depends on c OR b (but not on a)... c and b are the same but i must admit i'd forgot that algebra before the last slide myself :) .... by the time i got to the end of the talk though woah, was very cool, he touched on some really cool physics

43:00 As a lay-person I would have a ton of questions. The most important are, a) what mechanism makes a copy of the entire universe in the branching moment, in the time of 1 Planck time? b) where does the newly copied universe go if the other branch dies? or c) where does the newly copied universe go if the other branch doesn't die? All I can find as answers is "it just branches" and "the new universe just is there, somewhere, undetectable". That is the sorry state of QM, and it's no wonder physicists had no progress in QM for 50 years.

33:46 Best Moment^^ The little mermaid could have been saved by a beam-splitter and quantum mechanics ;)

Penrose is a genius of the 20th century, in the same league with Einstein, Plank and Feynman. Too bad the string theorists and Copenhagen crowd are too proud to give him the attention he deserves. No doubt, in 50 years his insights will be recognized and memorialized.

Anyone keep count of the number of things he would come back to in a moment, that never got back to?

Date and place of the lecture?

Naive question: if only 4 dimensions can manifest simultaneously, if a known dimension curled up at the same time that a hidden dimension manifested, would we even know? Could this help explain quantum mechanics?

You could see better into a black hole by shooting light into it whilst taking a picture of it with X-rays; or at least measure it's intake velocity and if it has spin.

Please, make a intro animation a little bit quiter. It jump-scares me every time. And thanks for the videos.

I was so happy that Roger Penrose won the Nobel.

“ The Unified Theory”is the first theory published in this subject! I am the pioneer!

Penrose is getting old. Not much time left for the Nobel prize, which he deserves.

3:30 it is the quintessence - the fifth (quinte) element (essence)

I haven't a scooby what's going on but gosh i love listening to clever people 😁

PLEASE make a post on the relation between DIV GRAD at finite density charge sources and the relation of this to gravitational curvature for finite density mass distributions. For zero charge density DIV GRAD X=0, while for mass the mass on a rubber sheet model suggests negative (Gaussian) curvature in the surrounding vacuum, suggesting DIV g

There is someone in my house down stairs but my door is locked, I don’t know what else to say. I was tucking my kids good night then saw this 🤷🏻‍♂️

Awareness is known by awareness alone.

Merlin apologizing for infinity cracks me up

Love Penrose! We think alike me thinks.

While "Inflation" is a assortment of assumptions (inflatory field that never been seen /etc) - this (at least) based on known & tested theory (General R). Evaporation of Black Holes implies particles with mass as well, not just photons. Still, definitely interesting idea how to deal with infinite size/time of expanding Universe...

Congrats to 🎉NOBEL laureate physics 2020 Roger Penrose..

is that Andrew Hodges in the corner at 7:15

Infinite°°

I believe chemical element #120 (8s2) is inside the center of stars and chemical element #119 (8s1) could possibly be inside of the center of black holes or even what dark matter might just be.

Ha style icon❤❤🎉🎉

Fall through. You're here with me, moreover you're at home, Roger. DOS

Random Maths Historian: "The concept of infinity has challenged and often destroyed the minds of the greatest mathematicians Roger." Roger: "Has it? Would you mind awfully holding my beer for a moment? Won't be long..."

Humans and nature abhor a singularity, hence strings and aeons (aka kalpas), and ? uncertainty principle and half-lifes (aka MTF). Penrose has good ideas, worth hearing.

Pure genius after Einstein

Heh... "The strings are fine..." But the violin has a problem? Or is it the violinist? I really hope I live long enough to see all of these theories resolved or reconciled. I know I likely won't, but it's certainly an interesting thought to have one final explanation of... everything. A far more interesting thought is what people's reaction to that might be.

This talk is so scattered and goes in all sorts of directions and then pulls back to go into another.

And I'm having difficulty already with just learning javascript... What with having to deal with cats...

I've ordered his book bearing the same title as this lecture, to read and try to digest at a slow rate. But this all seems to be lots of theories trying to make sense of our world/universe's reality. Not sure how much all of this is proven, provable or true - he ends up with oscillating universes. Theoreticians will be theoreticians!

Mathematical Connection @14:30, "getting used to that idea", rougly equivalent to the Banach-Tarski Conjecture in principle of shaped and functionally counted infinity, similar to the probabalistic antilog of the exponential, or hireachic dominance of the "musical effect" of temporal superposition. (Natural beauty?) Professor Susskind's comment is equivalent to this lecture from another conceptual beginning, that of the "amorphous" Quantum Fields Mechanism. (Or so it appears to myself) Still in the same context as above, the caused-effected eternally quantized-coordinated phase-state of the universe is a basis for comprehension of QM as it is presented by the double slit experiment, a state of co-existing cofactors of primes in duality that can be extended to the infinite limit of Calculus and reciprocals in unity, ..by rational steps of superimposed coordinated calculation (QM mechanism), ..in an infinite spectrum of irrational-functional shaped-dimensional "strings". (Something like the "hair", or not, proposed for black holes) If the observations of phenomena begin with the Unitarian property of time, the Universe is a Mathematical spectrum of quantum information. (Combining the lectures of Profs Tegmark and Rovelli) Fortunately, Faith and Fantasy failed to dominate the Quantum Fields Mechanism in Temporal Superposition Fact.(?) In any reasonable Fashion.

It boggles the mind that a man of such intelligence has never noticed that the double slit is not a quantum experiment. How do we know? It's trivial: Planck's constant does not factor into its description anywhere. It's like calling an experiment that has no electric charge anywhere an electrostatics experiment.

Would it be logical if positive and negative charge represent two extra dynamic dimensions within our three dimensional Universe of continuous energy exchange? This is an invitation to see an interpretation of the mathematics of Quantum Mechanics as a geometrical process of energy exchanges that forms what we see and feel as the passage of time! In such a theory the Planck's constant ħ= h/2π is a constant of action in the process that forms the continuum of time. Heisenberg's Uncertainty Principle ∆×∆p×≥h/4π represents the same uncertainty we have with any future event with the future unfolding photon by photon with each new photon electron coupling or dipole moment! With classical physics representing processes over a period of time as in Newton’s differential equations.

Certainly seems (to my simple mind) that he's on about a curiously finite 'infinity' at 13:40...

Gravitating bodies reduce entropy. That means the total entropy of the universe remains constant and the 2nd law of thermo is wrong

It is difficult to criticise a lecture given by such a distinguished ( and charming) theoretical physicist as Roger Penrose because I have no doubt that I am listening to one of the greatest living scientific minds. As a trained physicist myself I am familiar with the difficulties faced in explaining advanced topics to a predominantly lay audience but I think he probably lost many with such a muddled and ill prepared presentation. Fortunately, Penrose explains his ideas much better in print than in a lecture theatre; I have read many of his books and they are terrific. It is a great shame that such a rare opportunity to listen to such a great scientist ended up as a disappointing event.

I was reading the title like: "...with Roger Penrose... Penrose? ROGER F*CKING PENROSE?!" Instalike.

No overhead projector? :P

String theory is a mathematical explanation not a physical theory, all those dimensions, and how to test what does not make prediction? Absolutely agree, however it is ironic to me that the more conventional conception of physical dimensionality is more similar to this than it seems anyone gives it lack of credit for. 3 spatial dimensions is a mathematical convention and convenience as far as I'm aware there is no evidence for this as a physical theory, and I'm equally unsure as to how you would test such a thing as with the case of string theory.

has anyone read Walter Russel?

They should add Nobel Laurate to the title

❤hi❤ ### Concept Simplification and Background Until now, quantum mechanics has primarily been a theoretical and experimental field focusing on understanding the fundamental nature of the universe at the smallest scales. The equations and models developed, such as Schrödinger's equation for wavefunction evolution and Feynman diagrams for particle interactions, have provided deep insights but also come with limitations. For instance, Schrödinger's equation describes how the quantum state of a physical system changes over time without considering the probabilistic nature of particle interactions depicted in Feynman diagrams. Meanwhile, Feynman diagrams offer a method to calculate probabilities of particle interactions but don't directly account for real-time dynamics in quantum states. ### Existing Formulas and Their Limitations 1. **Schrödinger's Equation**: Describes how the quantum state of a system evolves over time. \[ i\hbar \frac{\partial}{\partial t} \Psi(r,t) = \hat{H} \Psi(r,t) \] Limitation: Does not incorporate probabilistic interactions between particles directly. 2. **Pauli Spin Matrices**: Used for calculating spin dynamics, essential for understanding quantum states of particles like electrons. \[ \sigma_x, \sigma_y, \sigma_z \] Limitation: Focuses on intrinsic properties of particles without detailing how these properties evolve due to interactions. 3. **Feynman Diagrams**: Visual and mathematical representation of particle interactions in quantum field theory, used to calculate the probabilities of different interaction outcomes. Limitation: Primarily a tool for prediction and calculation, not real-time observation or interaction. ### Our Proposal: A Novel Integration We propose a groundbreaking framework that integrates the real-time observational capability of attosecond pulse technology with the foundational principles of quantum mechanics and quantum field theory. This integration aims to overcome the limitations of existing models by allowing for the direct observation and manipulation of quantum states at unprecedented timescales. ### The New Formulas in Detail Our conceptual approach introduces: 1. **Dynamic State Vector Evolution**: \[ |\Psi(t + \Delta t) angle = \hat{U}_{\text{atto}}(\Delta t) |\Psi(t) angle \] A modified evolution operator \(\hat{U}_{\text{atto}}\) incorporates real-time data from attosecond pulses, allowing for the observation and prediction of quantum states' evolution. 2. **Real-time Feynman Interaction Integration**: Incorporating a computational model that dynamically integrates Feynman diagram interactions based on real-time observations, adjusting quantum state predictions accordingly. ### Uniqueness and Novelty This approach is unique and novel because it: - **Bridges Theory with Experimental Observation**: By integrating attosecond pulse measurements directly into quantum mechanical models, it bridges the gap between theoretical predictions and experimental observations. - **Allows Real-time Quantum State Manipulation**: Provides a framework for not just observing but actively manipulating quantum states in real time, a significant leap beyond current quantum mechanics approaches. - **Incorporates Probabilistic Interactions Dynamically**: Dynamically adjusts for probabilistic interactions between particles, providing a more comprehensive and accurate model of quantum dynamics. ### Meaning and Potential Benefits to Mankind This groundbreaking framework could revolutionize multiple fields, offering: - **Quantum Computing**: More efficient algorithms and error correction techniques, significantly improving computational power and capabilities. - **Materials Science**: The ability to observe and manipulate atomic and molecular structures in real time, leading to the development of new materials with tailored properties. - **Medicine and Chemistry**: Enhanced understanding of chemical reactions and biological processes at the quantum level, potentially leading to breakthroughs in drug discovery and treatment methods. ### Conclusion By integrating attosecond pulse technology with quantum mechanics and quantum field theory, we propose a novel framework that overcomes existing limitations, offering a deeper understanding and unprecedented control over the quantum world. This innovation opens up new avenues for research and technology development, with profound implications for computing, materials science, and beyond, marking a significant step forward in our quest to understand and harness the fundamental laws of nature.

I were having a pint with a gentleman once, when I came back from the loo he were being auled out and they put im in the ambulance. Away they did drive him, all screaming and fussing. Never saw him again. Reminds me of this fellow. G'day . . .

What is he talking about with the tetrahedron and rubbing two sticks together? Fire and Smoke... what!?

If I had a son I would want him to be just like Roger Penrose.😷

I just like to rave on when I see a great thinker so don't take any notice of this comment. I believe from my observations that Schrodinger's equation does apply to the classical world but is not seen because the classical world exists in time, whereas the quantum world doesn't. For example, If we think of a male as being representative of a particle and a woman as a curvaceous wave-field of intangibility, then when the male conceives a daughter, his essential being is transformed into her. She becomes a male him. Likewise when the woman has a son, he becomes a female variant of her essential being. Boys will be just like their mums even if they have never met. Likewise for daughters and dads. Then we have the time-idea of death as going into another realm or dimension. As we are scientifically unaware of what awaits us on 'the other side'. we have failed to make the connection. But if we look downwards at our pre-existence in the womb, we see that we were of a completely different pattern in terms of: We were upside down. We were alone. We were in the dark. We drank water not air. We were fed all our needs. All these parameters had to die or be inverted for us to be born. We became one of many. We now breathed air. We walked upright. We were in the light. So if we take 'time' out of the classical world and look at the dimensions of life all in the same field, then we see that when certain criteria are met our classical world can become an extension of Schrodinger's super-position if we understand a few spiritual principles about life, death, and intimacy. That's enough for tonight I thinks.

I am the Ewok and he is C-3PO.

I love Rogers mind, but he is talking to scientists here, not carpenters like me. 🙂 Just a wee bit over my head.

You get smoke then fire sir not fire and smoke

Thank you for you Sir-vice... Omg that was lame 😢 Forget that, Sir Roger...my mind can't hold a moth to your flame, can't see the forest for the stems and seeds.

whoever disliked this video just needs to smack himself with a book repeatedly, any book would do.

What a glory to be alive at the same time as Penrose, Hawking, Dawkins, and more!

Interesting. TIME REQUIRES CLOCKS! If you go into a space for ANY reason where MASS HAS NO EFFECT, such as at the end of our universe when only photons exist, then, because photons are moving at the speed of light and have NO TIME (thus are stopped or nonexistent clocks), the concept of infinite time DISAPPEARS (no clocks = no time) and you can now GO PASSED TIME INFINITY (in effect). Second, without mass, physical dimensions also have no more meaning (waves are diffuse) and so gravity, which requires clumps of mass, also disappears. Thus, SCALE DISAPPEARS and a nearly-infinitely-large space at the end of one "eon" (using Penrose's term) can be considered, for the next eon, nearly-infinitely-SMALL without changing anything. His stacked cylinders in the last picture should have been a series of stacked rings, each ring thickness in the time dimension being very long, but the WIDTH (space axes) of each ring growing enormously at each step, WITH NO EFFECT ON ANYTHING DUE TO THIS WIDTH CHANGE -- nobody in each eon sees anything different than in the smaller previous eons since everything is scaled up in proportion!!!!!!! It takes a mind like Penrose's, who can handle Penrose Tiling in 5 axes, to realize such things. Wow!!!

As someone who just listens to these talks out of interest, I feel like he was all over the place.

I am angry with the big bang cosmologists who keep adding more and more crap and just keep saying "oh yeah it makes perfect sense", forgetting what they were saying with certainty just a few years ago. This makes more sense, and doesn't make me angry at all.

4:50 Penrose is great but time doesn't exist

so many experts in the comments...

Toroidal Field

Well that was not one of those easy to get lectures I must say

Wouldn't there still be mass in the form of the scalar fields even when the last proton decays into photons? We now have direct evidence for the Higgs field. Unless it is at a false vacuum why would he expect it to collapse?

Infinity can't be a physical thing so how can infinity possibly find its way into natural philosophy, physics. Theoretical mathematical hocuspocus has misled generations of physicists. Starting with Newton dismissing Buehls view of the sun as electrodynamic.

Why doesn't QM make sense? For example light is only emitted/absorbed as quanta, but propagates like a wave. A photon does not split into two half-photons at the slits, it fully propagates through both slits like a wave. Also, his Schrödinger's cat adaptation not only misses the point of Schrödinger's gedankenexperiment, it's wrong. Only one door will be opened, because the photon does not split into two half-photons... It's either fully absorbed at A or at B - both options are mutually exclusive. That's really basic QM so I wonder why he made that error?

So reality is a blockchain?

Who is watching after waqas zaka show??

he looks like gordon ramsay in disguise
