[@JaimeLannister13]

Lex, this has been a very informative podcast for me (one of your best, truly). Thank you for breaking out the above for us. If I can follow up with a question for you at 1:11:20 when Roger discusses how the universe gets more boring as we near heat death and black holes begin radiating away. My question is: is it possible that they don't radiate away and that they instead manage to continue finding one another growing in mass until having a gravitational effect on the expansion of the universe itself causing an implosion instead of a heat death? Don't know if you'll get to this but thought i'd ask. Cheers,

[@bobbykotick1163]

[@senaesul3128]

Lex, I don't think consciousness is as complicated as many people put it (despite the sounding ignorance of this statement). Most of the battle in my opinion is the training of a self identity that carries memories of said identity. Our own consciousness is essentially trained illusion to believe our sensory inputs and memory make us separate from the causal link of the quantum universe. This all might be bollocks, please let me know if it is, thanks!

Penrose; such a humble man. Can't we find a way to give him another lifetime?

[@bruno3]

This kind of comment isn't ill-intentioned, but I always cringe when I hear or read things of the sort. When you get to a certain age, most people treat you like your death is imminent and that must be tiring and depressing. No one knows when their time will come. Just imagine how many young people have died since this comment was published and Dr. Penrose is still alive and kicking. Let's just see people for who they are and not put a life expectancy tag on them.

@@dawnkeyy I'm family friends with Dr. Brenda Milner who was the student of and worked with Dr. Penfield (I grew up around her and was flown out to Toronto a few month back with my dad as her 2 representatives for her induction to the Canadian Walk of Fame) and she's 105 and still able to have complex conversations! It's utterly amazing. She's clearly not as sharp as she was in her 90s and certainly not as sharp as she was when I was a kid but it's really quite stunning. Her and Penrose are both inspiring examples that make me less afraid to be old. The key seems to be to constantly learn and keep yourself open to novelty. Those who seem to lose cognition earlier (while there are certainly genetic factors) also seem to be those who "already have a closed worldview" rather than those who are always open to changing their minds so long as there is logic and reason to do so

I don't think Penrose's quote translates exactly to "know the rules so well you can break them". If I recall, it's not so much about breaking the rules - it would be more accurate to say that you follow all the rules properly and you break ~the machine~ due to the input you gave it. The fact that it breaks down translates to a logic statement that not all math problems are solvable. Correct me if I'm wrong - I'm paraphrasing & it's been a while since I dug into that stuff.

I have been saving this one for a while, it's well worth the wait. Thank you both for this! 🖤

[@BoRisMc]

Sir Roger Penrose seems particularly agile and well-rested in this interview. Really sounds like a sharp middle-aged man. I wish I was this sharp on my 36 y.o. Amazing work Lex!

[@jimbeam4736]

I´m 38 and felt the same...

[@QED_]

@Boris Martinez Castillo: Penrose steps through the totality of his interests and their development here . . . in a comprehensive way that I've never seen him do in a dozen other interviews. How does that happen (?) Does Fridman provide some kind of intellectual space that uniquely facilitates Penrose doing that (?) Very interesting . . .

[@thejing3793]

pay attention to the way he interacts with his body during this conversation, you can tell he is getting so passionate just having to share the knowledge of all that he knows.

[@TheTebban]

I was in awe when this talk was first aired, rewatched it today and I was almost in tears.

[@patrowan7206]

I just finished my second watching with the same response.

[@kevinkammueller7553]

Can you imagine the fun you could have being this guys friend and actually being able to talk with him about this stuff.

[@marzx13]

Amazing! Roger... Had to post this before the opening ad even finished. Super excited for this discussion.

[@hireality]

Roger Penrose is the most brilliant, fascinating, and lovable scientist and thinker alive today. Thank you indeed Lex for your most wonderful episode ever. Like another commentator put it: I wish this interview was lasting for 24 hours🙂 Shine on👍

[@northcotemallory9968]

Wow-One of the best interviews I've even seen!

[@ab8jeh]

Love the ending. I recommend a book called visual complex analysis for anyone that wants to delve into it. Wonderful book.

[@M.-.D]

So incredible to see Professor Penrose win the Nobel Prize. One of the greatest minds.

[@cristianorentroia6607]

One of the best interviews with Roger i have seen. Congratulations!

@Cristiano Rentroia: Yes. Penrose steps through the totality of his interests and their development here . . . in a comprehensive way that I've never seen him do in a dozen other interviews. How does that happen (?) Does Fridman provide some kind of intellectual space that uniquely facilitates Penrose doing that (?) Very interesting . . .

[@freeconsciousness7789]

Re-listening to this conversation made my morning beautiful. Have a great day Lex, thank you for everything you do. ❤️

[@soundman2604]

Lex, that was a great interview. I wish every interviewer was as patient as you are. It seems like majority of the hosts love to hear themself speak than actually learn something. Thank you!

[@donutstix22]

I am blown away. I have thought about consciousness in much a similar way that Roger Penrose has for awhile, and my thoughts on everything he said aligns perfectly with mine, and makes sense to me. I feel like he has advanced my understanding of how things work and my exploration of these thoughts by decades. I am immediately going to read and consume any Penrose material I can. His curiosity and intuition feels unrivaled. I am mainly writing this for myself, but it feels like every single thing he talks about is the most interesting concept in the world. Thank you for this podcast, and thank you to whoever told me to watch this video, I can't remember who you were but I am eternally grateful

[@henrydavidpurple8323]

Man I’m so glad I gave your podcast a shot. You are excellent at your interviews. Thank you.

[@noseonscent1935]

Superb interview with a living Legend! Bravo Lex. Many thanks Roger!

[@jeanlesperance3057]

Great interview. Started watching the Jordan Peterson discussion with Penrose but it got very bogged down and muddled. Lex was much better at drawing out Penrose's ideas.

[@arisrayden]

a discussion/interview between peterson and someone else got bogged down and muddled? why i'm shocked, shocked i tells you. never ever have i witnessed peterson getting bogged down and muddeling things up why i......can't sustain this level of sarcasm any longer

[@pedrofelipefreitas2666]

Jordan is an extrovert, he is usually well composed but maybe he was too excited when talking to Roger lol

[@AdamEvans416]

The guests on this podcast are remarkable, thank you Lex!!

[@joeimbesi99]

Penrose is one of my Physics Heros..but more importantly an amazing ,humble human who's stretched his mind into other areas...loved this.

[@vhawk1951kl]

The "humility" was plainly no more than an act, and positively oozed dishonesty.

[@joeimbesi99]

@@vhawk1951kl your patheric

[@niccijay4683]

@@vhawk1951kl Your lacking of humility shows how much substance your comments carry in relation to the subject. It seems all your intereted in is commenting absolute gibberish about this man. Penrose seems to live rent free in your head for some reason. Either way no one is going to take anything you say seriously, remind us what you have contributed to science, nothing, no one knows who you are, meanwhile Penrose will be remembered for centuries due to the insight he has gifted the world. You are a sad human being.

[@shanebakerstudios]

Lex's expression at 1:19:51 is exactly my expression while watching/listening to all his guests. It's frustratingly fun to and stretch my understanding of these ideas.

[@CozminVasile]

I now come back to this gem more and more often and I listen to it either to fall asleep or to have my morning coffee in the incredible company of Penrose. How smooth it sways between topics and thoughts and problems that swirls your mind. I, somtetimes to put the headphones on and max the volume to listen closer some passages, like finding new harmonies in a concerto.

[@Laurencemardon]

Oh look the nerd herd!!

[@Rossion64]

That was a fantastic interview. Sir Roger is exceptional

[@stakerul]

Can't wait to hear this! Thank you for this podcasts, they really help me during this lockdown

[@aperson2703]

I wish this was longer, it's a pleasure to listen Roger speak.

[@tonyhill2318]

One of the best Lex episodes. And something tangential....I greatly appreciate the quality of the audio....nice microphones.

[@laplacesdemon45]

I love how Sir Penrose says "you see" every once in a while :)

[@Ly0n64]

Really, Thank you for this Lex. This was a really beautiful talk in many ways. Very much appreciated.

[@doodle6004]

Amazing. Wonderful interview. Thank you for bring us this.

[@nikilesh]

What an amazing mind to listen to. I can listen to Dr.Penrose all day.

[@keifw8199]

Apparently I picked a great time to start watching these podcasts. Can't wait to see who else you've had the pleasure of talking with on this channel

[@MyNameIsCheyne]

I got more out of this than any other podcast/interview ever 💯 thank you -

[@johnpenner5182]

such a good interview! - thank you lex & roger!! 🙏🏻

[@CUBECASTMRV]

Absolutely inspiring listening to Mr. Penrose. Very nice dialogue Lex!

[@_Skim_Beeble]

This channel is like Joe Rogan without the weed, questioning the nature of everything is what rational people do. Thanks Lex for keeping us sane during these crazy times.

[@bernardd]

Rogan has interviewed Penrose but he could only barely scratch some of the topics. It's not really Rogan's fault. Penrose demands an interviewer who has the background to at least learn about the notions being discussed. Lex did a very good job here.

[@anxiousmindmusic]

Still plenty of weed being smoked while listening to Lex... Definitely a different tone but you can still feel how much he has been inspired in stye by Joe. The end result is great either way.

[@bailey31909]

thank you for this podcast. It was very interesting, at times hard to follow as I have no higher education in physics or mathematics than basic college courses, but your ability to summarize what was said is most helpful. I will listen to this one again.

[@Excalibur32]

These interviews are critically important, thank you as always

[@ronnie-codes]

This old man is brilliant. Well done.

[@afz902k]

Greatly varied and interesting subjects, for me both the discussions about the nature of consciousness and the infinite cycle of big bangs were extremely enlightening, the analogy with the infinity we perceive in fractals really lands it for me.
