Black Holes, Symmetries and Impossible Triangles - In Conversation with Roger Penrose 

I see Penrose, I click. This guy is a relief and a beacon of sanity and common sense in the popular science community.

Thank you to the interviewers for not cutting him off every 30 seconds like interviews on the major TV networks.

Finally, dude gets standing applause, recognition and respect that he deserve years ago. Glad to see that, better late than never.

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.

Roger's ceaseless curiosity is inspirational. Even at 90, he's on the frontier of physics and hungry for more knowledge. Thank you Sir for your work.

Sir Penrose speaking out a lifetime of study in only a few minutes. Magnificent.

I don't understand so much of what he says but it is still a bliss listening to him. Any crumbs that do get through my thick skull are gold!

*Of all of Sir Roger's traits I find it the most endearing how he readily, even happily, admits to when, where and how he has been wrong. What a true genius!*

Such an amazing man. The mind he has at his age is incredible. His form of thinking is just a step beyond. And he's so personable to boot!

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!

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.

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

Wow ..... *Professor Roger Penrose* is here .... This program is just GREAT I'm sure! Thank you so much dear *Ri*

Outstanding mind. He has rare ability to have a fresh look at complicated things. Love to listening him

Such a clear, razor sharp mind.

Absolute proof that following only one course of subject will end in being wrong. Opening yourself to multiple subjects, wether mathematics, physics or art give you a much more developed sense of seeing the complete answer. (Or as complete as we can so far manage, we need more scientists like this)

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.

In Sweden, we skipped all titles in the sixties, except for the royal family. Makes social interactions so much easier. But this man I would definitely address as Sir! So smart, well spoken, and a real joy to listen to.

Always a delight to listen to him!

Sir Roger is a gem, so good to see him talk and just effortlessly show his genius

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.

Roger is on a different level, Very few can grasp his intellect.

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.

Great talk. Happy about the focus on his tiling and Escher, where basically his genius started...and inspired others with it

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.

Congratulations for having Roger Penrose tonight and giving RI subscribers the opportunity to enjoy his memories which are live History of Science.

This is a great interview. Thank you for sharing.

Uncle Roger ! I was searching for something interesting to watch while having my supper ! I've found it right here !

Thanks for uploading! He is such a brilliant mind! Best wishes from Germany, Becky

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?

It's fascinating to hear Dr Penrose talk about 'coherence'... on and off for years I have been working on a book that describes the universe as being ordered by: chaos, simplicity, synchronicity, and is 'held' together by coherence... held together can be interpreted many ways.. but fundamentally it is a means of communication that also acts as a bond.

"for those of you who don't know who Roger Penrose is, Martin has pointed out where the exits are""

Wonderful insights and discussion, excellent watch, Thank you

He is 90! The clarity of mind with which he speaks astonishes my foggy 39 yo mind!

Incredible! Such a joy to listen.

More Penrose Plz! Longer, do a Penrose series. Thx

As a layperson that is always searching for more information, I find this completely fascinating.

This was fabulous. Thank you!

My favourite part from the lecture :- Proof procedures can only give you solutions but it cannot give you proofs of those solution. Only consciousness can provide proof of any solution. Consciousness > Computation.

Wonderfully interesting!..Wish there was more time for the various topics but particularly towards the end on Schrodinger's equation/cat/ collapse of wave function, relation to consciousness, and the need for more than algorithms to enable us understand things..

I missed my dentist appointment. I couldn’t tear myself away.

No wonder Penrose is full of praise of Alhambra, that held 400,000 books in the library that were translated and enlightened Kepler, Copernicus, Galileo, Fermat, Descartes, Leibniz,, Newton, Euler and many more, Penrose is only celebrating this great gift, along with the tiling, the work of Persian mathematicians. Penrose's biggest contribution is his conviction that 'mathematics is based on faith'. He deserve the Fields and a Nobel.

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.

yess!!! Finally back online!

The 'Road To Reality' is a modern classic and l hope will be available to all for many years to come. An excellent classic!

Thank you very much The Ri for sharing this "Giant Man" Great content 👍👏

The epitome of humbleness in the whole scientific community!

This is amazing thank you!

This man is eminently listenable to.

Loved the PBS Space Time Spinors and the Numberphile 3 gear axle. Seemingly impossible, yet possible.

Thank You Mr. Penrose.

It's a delight to listen to Penrose. BTW, watch how the interviewers are drinking water all the time and Penrose is only talking.

The sharpest 90 year old I’ve ever heard.

Absolutely fascinating!!!!!!!

I just hope against hope that he has an army of students to carry on his work.

"If you dont know who he is, please leave quietly " what if I wanna learn?

he really got the field no bell prize 3 years in a row. hes in his 70's

National Treasure… World Treasure

Now I understand why Lee Smolin talks about Penrose that way

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.

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.

Chalk to board this... A bicycle aluminum wheel 12 pistons 12 accordion style airbags 12 weightlifter weight caps The airbags are all half-full of capacity The pistons allows fully open on one side and fully closed on the opposite side of the wheel. Synchronized movement. Put it on an Axl mount under water and what have you done ?

One of the few open-minded, non-ideological people in the hard sciences. Refreshing.

A timeless beatiful mind...!

Yang-Hui is really excited to be there talking to Roger, as I would be!

I would have like the chance to see the q&a at the end

Well done for media work

I loved the *Altair IV* colouing book.

What date was this recorded? Please edit the video description. Thanks!

Chalk addiction, brought to light by Einstein level scientists! Love this !

The amazing thing is that he's 90 but probably wouldn't think of retiring. not when the brain is still continually looking for new connexions, exercising that grey matter seems to be the secret, or maybe it's the microtubules

Sir Roger Penrose : Absolutely Interesting 🤔

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.

thank you, the best thing - think on the internet

My Idea - Gravity as an impossible triangle. Take the triangle inequality c < a+b then add a function to the distance c to the object and miss classify its height. The object must then either move away far far away or move down to correct the problem. So gravity is a miss classification of height distance function //Per

Thanks!

Amazing 👏

All these live on one concept waves❤❤🎉🎉

People don't usually mind getting up in the morning for a Nobel prize - slight understatement

"It all comes down to companionship more commonly known as love. It is this the reason why. Now we in the field of science can continue to talk endlessly around this truth and speak half truths, or, we can speak the truth, the whole truth, and nothing but the truth which is that the purpose of self otherwise known as the meaning of life is love." - Wald Wassermann, Physicist, Center of Theoretical Physics.

Which date was this? Nothing in the description.Was it before COVID?

At 47:00 at the height of the most intriguing part of this entire lecture the host complained about the time. I was thinking don’t mess up the Kepler story!!!

@ 40:16 The Penrose Tile looks regular, but it's not. That is the thing I like most about it.

Find time for this man!

The pictures are great. I enjoy the organization of pentagons but I still can’t find the pentagins

The universe is full of unspoken knowledge. No doubt unspeakable knowledge, concepts beyond the limits of human grasp. Also is the knowledge which can be revealed via understanding such as the double helix of DNA and stored knowledge.

@ 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.

Are the photos of black holes indicating of any flattening of the poles and increasing the equatorial radius? Due to rotation of the matter on entering the black hole- which shall cause the existence of centrifugal force inside. Stary

One hour certainly is too short. More! :)

What a wonderful mind

johan de witt also worked on the problem of Penrose tiles.

It’s the most accurate language we have but like any language you have to get the translation right and good writing.

It's easy to be puzzled by why a guy who understands patterns (Penrose) is considered to be a genius. Then we listen to him talk for an hour about AI and consciousness and what is and is not a mathematical proof, etc, then we have an inkling of why he is a genius. He thinks about the subtle meaning of things like quantum mechanics. Be honest, how many viewers understood that Schroedinger with his cat was trying to hint at why his theory did NOT constitute the last word in a theory of the physical world. It was news to me.

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

Alfred Nobel didn't create the Nobel Prize, and he died in 1896. The Nobel Prize was created from his testament and will, after he died. The first prize was *awarded* in 1901.

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 wish they'd let him talk more about the collapse of the wavefunction

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.

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

Description fails to say, but apparently this took place on October 26, 2021.
