42:43 Many worlds (Duality: wave vs particle): History is acquired information = observation / The future = predictions / unknown. Therefore, wave functions can be considered History (factual) and particles (fictional and /or non fictional) can be considered the Future. However, the unknown may be considered either knowing reality of one's environment (yes or no answer), or not knowing reality (confusion/ chaos), which may be due to deception or not having enough acquired knowledge from one's experiences, I think...
Any bioinformatics podcast in the future? Such as ML for drugs discovery, ML/non-ML genomes sequencing, pattern recognition for medical diagnosis (CT, MRI, blood, heart beat, eyeball, medical record etc.), discovery for epigenetics expression & reprogramming(e.g. mechanism for diseases ) etc.
That's jokes, i had a similar fleeting visual, where when the camera turns off he just powers down and goes into stasis, quietly humming away until the next interview.
This podcast is an absolute game changer for education. Casual yet informationally dense conversations with people who can nonchalantly drop high Qs for those of us with low Q's. Honestly, appreciate this archive Mr. Fridman. It's reminiscent of the 19th century literature that had a wonderful focus on comprehensibility versus crippling esoteric jargon of most journals I read today. Спасибо большое Лекс
Broken with respect to the individual, yes, but not in the eyes of the state who design it, and who's needs it serves. It creates the strata they think the economy requires. Restricting critical thinking is fundamental to the slavers maintaining control. This is controlled, by design and it transcends all socioeconomic groups. It's how you get a professional class full of people clever enough to do the work but still can't see or think clearly. When you operate a war economy in service of an oligarchy, and the PR, lies and faux theatre of democracy is how you get away with it. Then it would be existentially risky for the slavers to teach the majority to see through the lie that controls them and keeps them being useful.
I have never heard it so clearly expressed. “We have discovered science is not organized around our intuitive structures of meaning, purposes and goals...., just patterns of what is.”
Well he can want that in one hand and poo in the other and see which he notices is full first. And the false data collected will unfortunately negate the initial statement of desire from coming to pass. But ignorance is bliss. He should have just said, "I hate people who believe in God." And if he were wise, he would at minimum, recognize he might be wrong about that belief. At best he would recognize God does exist, just as Newton knew. The doctor is otherwise awesome.
@@Jamie-Russell-CME I used to blame believer's God for us having limited human beliefs. That backwards thinking got me hateful too, I'm sorry to admit..
The conversation is almost always different when a high level theoretical physicist is on the show, they really elucidate answers to difficult questions the versus other guests of different disciplines. Shaun is an awesome thinker.
I haven’t even watched this yet, but anything with Sean Carroll is worth my time. Thanks for the upload! Glad you were able to get him back in, after the tragic way your other interview with him was cut short.
It's nice listening someone speak on something I'm extremely ignorant about. I have no reason/time to get upset or disagree because I'm just trying to understand what you're saying. Awesome conversation.
I love what you're doing Lex. This podcast is what I've been waiting for my whole life. Finally, a person that can get smart people on to talk about super smart shit that's 80% over my head but 1,000% better than 99.99% of the podcasts out there.
Bob Ross will make you put aside everything you question and/or "hate" about reality, and just enjoy the fact that we're all here, and that colors and canvas exist. That's a rare quality that a tiny, tiny percentage of some 7.8 billion people possess. I'd put your interviews among the same rare, enjoyable skills, Lex. Your content has helped me through the worst few years of my escalating mental health issues, and I'm forever grateful. I understand the odds of you seeing this are as tiny as our place in the cosmos, but that's okay...I thank you with the exact same gratefulness and enthusiasm.
@@zachvanslyke4341 I’m actually doing well. It took many long years to get to this point but I feel like I’m okay for the first time in decades. Thank you for your comment.
Im going back to school to pursue my dream as a particle/theoretical physicist. I have a model I want to work on and need the credentials for anyone to take me seriously. I have a thesis that explains gravity and dark energy to a fine point and everything else just falls into place so elegantly. Its much more simple than you might think. Im just so excited about the Universe and all the mysteries of the Universe. I cant wait to go back to school and finally get to a place I belong. Thanks Lex Fridman, Thanks Sean Carroll. Thank you to so many others who have all been a positive influence in my life and helped me reignite that spark of wonder thats always been here inside my soul. Peace.
you serious?? study (FUCKING HARDCORE BOSS MODE) physics to prove or disprove your worldchanging model of cosmos&shit??? thats BADASS! sick, but badass♥!! me wishing you all the best and all fingers are crossed for you to succeed- to become a physicSbossmodefreak, fella! *set a bookmark and let me know in a few years, what your studies found out... imma remember your cosmologic ass fo sho ;) LOVE PEACE & TECHNO ♫♥♫
@@davids9522 I'm seriously thinking about doing the same thing! Although I can't say I have come up with a new theory. I hope your journey is going great! And peace to you as well :)
I started this video without watching part 1. I thought ' who is this guy I've never seen and how did he get Sean Carroll to sit and talk for so long?'. Now I'm subscribed and getting Sean's new book. Sean is so good at explaining the most complex concepts, even describing limitations of language where applicable. He really understands and communicates his understanding. Like how people describe Feynman
What a fascinating and insightful talk! Glad I just discovered this channel and this episode. It's not often my short attention span can sit around for a full length 30+ minute video without endless pauses, breaks, and distractions - but I was glued to this from start to finish.
I was going to post the same thing lol.. That's just how a great mind focuses I guess.. and on top of that...why does Lex always sounds like he just had a gigantic joint?
His constant, perfect and consistent description of Quantum Mechanics, its history, foundations and modern state amazes me everythian time. And special thanks to the man in black. That's rightly the way I'd like to interview Sean and few other QM sages if I had a change. In some split universe, maybe I am!
Lex is one of the greatest podcasts out there for us not wanting to hear about the latest fashion trends or viewing “gold digger pranks”. :-) Keep up the great work! Interesting, educational and inspiring.
First of all, I can't believe you're 40 bro. You're doing a great job at staying healthy and young. And you're a scientist/engineer? I just stumbled on your channel and I'm obsessed. Your way of interviewing is unlike any other. You're changing people's lives for the better by having very complex topics explained practically, and sparking interest in people when in many cases there was none to begin with!. Keep it up Lex! I'm seriously, very seriously, considering going back to college and pursuing a more science related major than liberal arts, that I have now - because of you and your interviews sparking the childlike fascination within me again for science. Thank you!!!
Ruani Tafolla: Absolutely right..It's amazing. He sounds (from his delivery and slurred speech) like he's drunk and on drugs, but somehow, he keeps it all together to ask Sean, some serious, astute questions...so weird!
We've been used to people conducting interviews in a theatrical way, fine tuning their voice intonation to fit a narrative or fake amazement. He doesn't do that. So he stands out and appears bored and, to some who cannot do without this theatrical trickery, boring. We've been bulls**ted into thinking that the salad requires vinaigrette to be tasteful (which, in the case of a real salad, let's face it, is the case 😁). I find it a much more honest way of interviewing. No need for a cheap veneer if you're truly interested: it'll show in the questions you ask and the dialogue that ensues. I, however, cannot listen to Mr. Friedman at speed 1x. I play all interviews at 1.5x.
Sean, You are amazing and are a saint to sit through such an interview. You do help us to conceptualize and understand these concepts. If only there were mathematicians who did such things we would all be way ahead of the game.
Great interview. I like Seans podcasts but, I wish he'd do video along with audio. I find it a lot easier to tune into the concepts being discussed when I can actually see and, in a sense, feel better - who they're coming from. Sean if you're reading - Video plz!!
What a fun philosophical discussion! Most of the concepts they discuss are completely outside of my comprehension, but the way Lex asks questions allows us to gain insights into some higher level philosophical ideas that are hard to understand. This is a podcast worth watching...and re-watching.
Great conversation. I’m a moron but I’m curious and I’m thankful to the fact that I’m able to listen to such great conversation. So thank you Lex m Friedman! Keep it upd
You both have such unique styles of conversing, yet you compliment one another and that helps me to conceptualize the topics you cover. Thand you both very much!
It was meant as a put down, for the adults in the room to understand. The same adults that recognize charlatans like Carroll, because they have lived long enough to meet a few charlatans in their time.
@@rickycouture7224 I just imagined an image of your uncle with an afro, a brush in his hand, a landscape painting behind him and his name at the bottom of it. If Lex saw such an image, he'd fall of his chair ;D
I love when apes like me almost get lost and than a lovely chart or animation pops up to get me back on track. Simple, yet Brilliant addition to the podcast
I recently finished the softcover of Sean Carroll's book "Something Deeply Hidden," a title that has become my reference encyclopedia for those things quantum. I rarely comment on videos but had to tell you how striking your intro was when at 0:24 you said, "Listening to Sean... reminds me of Bob Ross teaching the world how to paint." What an astutely creative metaphor. I smiled when I heard it feeling the perfection in such expression. "Yes," Sean Carroll's every man way of making theoretical physics relatable IS Bob Ross-esk, and it was your brush strokes painted upon the canvas of introduction that crafted for your audience the consummate picture of who Sean Carrol is and the gift he brings those willing to suspend disbelief.
Great interview as usual Lex! Thank you very much. I was wondering if you could include questions about Godel's incompleteness theorems in one (or more) of your future interviews.
Coming from a highschool dropout who can boast of nothing but a somewhat curious mind...First time I was introduced to this theory by Mr. Carroll I had really no idea why he was saying. When I had little moments of "understanding" pop into my mind they would pop back out as soon as I tried to dwell on them. Like a wave of understanding collapsing into just words when I would try to step back and observe them. But I was determined...not to fully understand everything he's saying, but to understand why he believed something that seemed so utterly bizarre to me. Why Sean, why? I can happily say that after dozens of hours of interviews and talks and reading his book Something Deeply Hidden, I get it! Not that I totally understand quantum physics (Who does lol?) but I can see why he so strongly believes this interpretation of it. This is the first chat I've listened to since I finished the book and now I feel a sorta superposition of understanding this. When I try to measure my level of understanding I may find I think I do, then I don't, sometimes neither of those but usually a bit of both. Great interview Lex!
Sean Carroll is a national treasure. Great communicator and so knowledgeable. Recommend the Mindscape and AMA podcast. And loved how he countered the notion that human beings lack the capacity to truly understand reality and the natural world. I don’t think humanity is as ‘limited’ as some believe (especially those enamored with the idea that machines and AI systems are vastly ‘superior’ to the lowly human) so Carroll’s perspective was refreshing. “So of all the worries that keep me awake at night the human mind’s inability to rationally comprehend the world is low on the list.”-Sean Carroll
LEX! **clap emoji** drilling into collapse theory to get Carroll to talk about epistemic prediction system was extremely insightful and a true testament to your interviewing prowess
"Something Deeply Hidden" is very enjoyable! I highly recommend getting both the hardback and audiobook and consuming the simultaneously =) Thanks, Lex, for another awesome interview!!
Lex, youre podcast is what I've dreamt of for over a decade. Thank you for asking the questions, hosting the guests that propose genius solutions, and sharing it with the inquisitive minds who's intellectual thirst isn't quenched by trash video apps and mind controlling social media. Stay Golden Pony Boy.
I love Sean , his restraint from wondering into the mystical is amazing. One time way before I ever stated listening to Quantium Physics I had a revelation that since everything has its opposite it accord to me that everything thing is happening in ever possible way with out beginning to no end. Like an exponential multiplication it fans out in all directions growing exponentially faster and faster. I come to the understanding that there are many me’s but the view I see is a predetermined view based on my choices. So this explains why free will and determinism have equally good argument ha ha everything has an opposite that is equally true. + - are equal in there validity and good and bad connotation is to be taken out of this. So picture one molecule of h2o in a river it has a movie camera on it and this represents me. I start my journey with all possibilities open to me and as i go i find it harder and hard to cross the whole river. I can effect my position only so much based on prior decisions. Going from poor to rich would be an example of crossing the river. I can easily start making more money with effort that might get me close to the middle but getting all the way to the other side takes some doing. Sean its not an accident its not mathematically possible to be an accident. When you speak truth you and the universe as a whole “the bigger picture” become entangled. It is and it isn’t both are true they both have to be true or none of this works.
Now i wish i had spent more time and been clearer. Sometimes i leave out the commas and it sounds like a run on sentence. Honored for sure lex i watch you all the time i think three programs today. I also watch Sean where ever i find him as he is very smart and genteel in the way he explains things.
Awesome, as always...many worlds is very similar to the "Seth Speaks", by Jane Roberts explanation of the nature of reality that I read in the 70s...a channeled series of books
May I recommend T.S. Eliot's Four Quartets? ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ga8tQrG4ZSw.html I also find great value in the lectures of Alan Watts (also readily available on RU-vid). Namaste
Honestly one of best episodes Lex has had yet Liked it more than the Rogan one because Sean was given a chance to go deeper and elaborate more on his complex views
Wow Sean explains multiple ideas here that I’ve had explained many times before that never sunk in until he described them here. Thank you both for this episode
I would do anything to have had Sean as my college physics teacher. Thanks for this effort of getting Professor Carroll’s public-relatable understanding(s) (certainly a subset of his universe) of today’s physics captured. I love the FOMO to infinity and beyond, reference. Isn’t that the motivation for all research efforts? The FOM understanding (FOMU). I wonder if Sean thinks about the branching into many universes as providing the entropic driving force for the arrow of time by increasing the degrees of freedom. Some of those increased degrees of freedom are lost in access by being branched into other worlds.
Sean Carroll is one of the most (if not the most) scientifically and philosophically thoughtful and articulate thinkers that I am aware of. And Lex isn't afraid to appear unknowledgeable in posing touchy-feely questions, which is very effective in eliciting answers that bring confusing concepts down to the level of non-physicists. Not that Sean needs special elicitation to speak understandably, and notwithstanding the Lex's common-folk line of questioning, it is clear that he has researched the subject area of his interviewee and understands the landscape and the landmarks.
I recently came to a thought like that Aristotle's arrow might be correct: that quantum mechanical forces are actually a different form of time dilation: where instead of f=ma in a quantummechanical/electrodynamical collision there is actually an increase in the speed of time, or decrease behind the object which makes it move*, just like time dilation. Which is similar to the air around the arrow pushing the arrow forward as Aristotle says. Just speculating *causing something behind the object causally seems unlikely or implausible, so therefore it must be an increase of time in front of the object instead (where it hits). So basically some form of 'anti-gravity'
Lex, you're knocking on the door of such deep understandings for yourself. If you have not yet investigated the matter of psycho-physical embodiment such as it occurs in dancers or actors, for example, you really ought to. Your work as a musician can be a doorway into the understanding of how performance operates according to a kind of field dynamics and the rules of probability. It's the perfect time to integrate your body-knowledge!
Sean, holy shit, what a boss. Most people who have never studied QM have no idea how hard it is to understand this stuff let alone to explain it without a single equaton.A true master.
I think Sean's comment about training our intuition is a little bit like learning languages. When you first start learning a new language you have to translate each word. The process is slow and difficult. But over time you become so good at it that you manage to think and dream in that new language. Maybe our intuitions work in a similar way.
Sean's propensity to put every difficult physic problem into layman term. Lex's interests in other fields' especially their somewhat relevancies to AI.
Well there you have it folks, the universe is just a vector in the 10 to the 10 to the 122 dimensional vector space. Nice and clear. What's all the fuss about?
Congratulation on having one of the greatest minds alive on your show. We need to promote more people like Sean in all other disciplines to lead us on our journey through the universe..
It’s really not complicated but there are many ways to wrongfully approach an explanation. it’s not the students that fail to understand, it’s the poor approach from the presenter or failure to detect the lac of understanding.
Lex! I'll try and doodle for everyone... Sean is spot on with the power of visualizing the concepts most simply. All that we need are Fields of Vector Divergence / Curl and how each imaginary or literal measured point has a vector associated with Di-Electric universal constant's frequency. Then on that same imaginary or literal measured/observed point for a moment in time there are simultaneous Planes that intersect at various angles. Electric, magnetic, Strong force are all interacting and thus non Orthogonal planes to the Smaller scale Torsion Momentum Field (Stern Gerlach or ATLAS at CERN can measure this timescale frequency determined by the universal constant of torsion / quantum spin / Gaige theory). Then we get to Gravity and the thing Sean does not mention is critical to conceptualizing ==> Gravity Field appears to be perfectly Orthogonal to the other 3. The primary 3 forces likewise appear to be orthogonal to that even smaller scale Torsion Field....
I love lex because for the first like 10 secs of the question he's asking, he sounds like he's about to ask something really dumb and obvious, then it forms into a really pointed question that I become really excited to hear the answer to
