A Brief History of Quantum Mechanics - with Sean Carroll 3,157,334 viewsFeb 6, 2020 The Royal Institution 1.22M subscribers The mysterious world of quantum mechanics has mystified scientists for decades. But this mind-bending theory is the best explanation of reality that we have. Sean’s book "Something Deeply Hidden" is available now - https://geni.us/jrBLV Watch the Q&A: https://youtu.be/Jv5FYrOthvE Whether it’s Schrödinger's cat or the many worlds interpretation, the ideas quantum mechanics throws up about the reality we live in can seem incredibly strange and daunting. In this talk, Sean walks you through the history of quantum discoveries, from Einstein and Bohr to the present day, guiding you through the most intriguing subject in science and explaining his own favourite theories along the way. Sean M Carroll is a theoretical physicist, specialising in quantum mechanics, gravitation, cosmology, statistical mechanics, and foundations of physics, with occasional dabblings elsewhere. His official titles are Research Professor of Physics at Caltech and Research Professor at the Santa Fe Institute. He lives in Los Angeles with his wife, writer Jennifer Ouellette.

Marko Manninen Marko Manninen 2 years ago To me, it looks like Sean is reaching a mature pedagogical perfection in Quantum lectures! It is always a great service for students, researchers, and seekers to see and hear lucid talks like these. Thanks and looking forward to the progress of the theory. 481 The Royal Institution peter burandt peter burandt 4 months ago I have spent 56+ minutes suspended in a state of superposition of both, understanding and not understanding Sean Carrolls lecture. And yet I have enjoyed it immensely and consider it a time well spent. Somewhere in a multiverse of possibilities I am ready to receive my honorary quantum mechanics degree. No, wait... the cat is actually asleep. 194 Jan Willem v.d. Gronden Jan Willem v.d. Gronden 6 months ago It is amazing how again and again he is able to shine this light of knowledge and understanding on a subject so complex, yet through his knowledge and ability to compartmentalize pieces of information, giving the audience a sense of understanding of something otherwise well beyond it's reach! Amazing. 23 Nabil Freeman Nabil Freeman 1 year ago This was amazing. It summed up the reading I've been doing over the past few months and filled in a few key gaps due to the excellent explanation. I'm so inspired by this research and wish we could fast forward a few years like Sean said to see a fuller picture of how quantum mechanics may describe our existence. 👏 11 da tang da tang 2 months ago This is way beyond my expectation ! Best lecture on this topic I have ever learned. I am so grateful to find this lecture. Allow me to express my highest respect to you Prof. Carroll. 4 Peter Schmitt Peter Schmitt 1 year ago Absolutely wonderful presentation! Clear, logical, and optimistic! Thank you! 12 jmcsquared jmcsquared 2 years ago As much as I think many worlds isn't right, I love his attitude. He isn't sugarcoating the problem, he's attacking it head on. Nobody knows how quantum mechanics works, and we'll never know how gravity interacts with particles until we understand quantum mechanics, at least better than we do now. 109 Allan Blonde Allan Blonde 4 months ago 🙃This is one of the wonderful lectures about 'reality' available to all on the internet. How lucky we are! We don't even need to be matriculated at Cambridge U to be privy to it. Thank you Mr. Carroll and to all those others responsible for making this [and I might add other great lectures available on the internet] to everyone who wants to be more excited about the universe. 12 Juhani Heinula Juhani Heinula 4 months ago A great lecture from a great lecturer! He should be given the Nobel price for a fantastic lecture about such a difficult subject. Even I, as a retired engineer, could understand something to my satisfaction, at least. 1 johnpearcey johnpearcey 1 year ago Great lecture. I've always felt uncomfortable to admit that I really don't understand quantum mechanics, especially as I have a degree in Mathematical Physics! So thank you Sean Carroll, I'm beginning to get some understanding now! 55 SirCrest SirCrest 1 year ago Sean Carroll is such an excellent speaker. I enjoy all of his lectures. 3 WillBrink WillBrink 1 year ago 🤓 A Brief History of Quantum Mechanics 🤖 I find Dr Carroll has a real gift for condensing and explaining some of the most complex topics/Qs in all of physics. The entire topic of electrons not actually being particles, not sitting in their neat little orbits around the nucleus as still taught, is just mind bending stuff, at least to me. I glean a ton from his talks and anyone even remotely interested in the topic will enjoy this. 2 Alex Moreno Alex Moreno 2 years ago This is one of my favorite videos ever. Really convinced me both that the Many-Worlds interpretation is a good way of thinking about the universe, and also that trying to interpret quantum mechanics is philosophically important. 80 The Royal Institution Craig Wall Craig Wall 1 year ago Good job Sean! I'll be watching this repeatedly to "mine" your presentation of the Many Worlds paradigm. I too have been thinking about starting with Planck's granularity and working up to macroscopic physics; your comments on that approach are a welcome bit of encouragement. 6 Jan Behrends Jan Behrends 4 months ago Brilliant! Thank you for lifting my incomprehension of Quantum Physics to a much higher level. I do like the fact that you take inconsistencies between theory and experiment seriously and would like to suggest that better experiments will be needed at least as urgently as new theories! 14 Charles Miller Charles Miller 1 year ago The best lecture on this topic I've ever heard! Thank you Dr. Carroll. I envy your students! 50 Charles Garber Charles Garber 1 year ago Question Sean, what if the fact that what we are observing when uranium decays are fields at their highest possible energy state, hence why they behave as if they are particles, but they are in fact the electron fields moving through space and are merely compressed by the energy state? 5 Mithras Mithras 1 year ago Sean Carroll is arguably my favourite physicist. So nice to listen to. 3 Rodney Johnstone Prime Rodney Johnstone Prime 1 year ago I have never seen a hop to the left executed with such scientific fervor! I love Sean Carroll....all the different ones in all the different universes! 105 Rayner Stuel Galid Rayner Stuel Galid 4 months ago I have been asking this question of the Multi-Worlds interpretation for sometime without someone answering to my satisfaction: Why does (the reason(s) that causes) an event split and why does a thing becomes many versions of itself? 1 Malcolm Mellon Malcolm Mellon 1 year ago First time I've actually been explained to on how you arrive at Many Worlds, this is a really excellent lecture on the current state of quantum theory for the (educated) layman. I can't enthuse enough about how clearly and methodically you're taken through the description of the arguments, so you're just ahead of his conclusions and cry "oh yes of course!" just before he comes out with it. 13 Stewart Keigher Stewart Keigher 4 months ago Simply fabulous and a really lucid example of testing thinking skills before reaching a scientific conclusion. I'm buying the book!! 2 Guillaume Nobody Guillaume Nobody 11 months ago (edited) Great lecture, many thanks. I hope you can present the results/conclusions of your entanglement theory soon 2 Atish onal academy Atish onal academy 1 year ago I'm very thankful for providing this lecture . It's very helpful not only for the students but alo the teacher I can understand clearly and Easley quantum mechanics by this lecture but I have a question regarding electromagnetic wave because I personally feel that F=qvB (v=3×10^8 m/s) electromagnetic force equation .if we shall make a hole of matterial that allow to cross electromagnetic field and rapping a high voltage wire over this hole pipe and put some charged vehicle such it is perpendicular to the electromagnetic field that I think it's velocity should be equal to speed of light please suggest my question of answer it's May be possible or not 1 Joe the Geographer Joe the Geographer 4 months ago Absolutely fascinating! Already watching it a second time, thanks for posting. 1 Aux Mobile Aux Mobile 4 months ago A very interesting discussion could stem from the type-III multiverse hypothesis, described so eloquently here by the Professor, concerning the brain, consciousness, and even the nature of death. 3 Ronald Jordan Ronald Jordan 2 years ago I don’t know about anyone else but the last part was my favorite :-) what I think is so interesting is the idea that empty space is not empty. I know Lawrence Krauss has talked about this before but it’s a real mind bender and I can’t wait to see what comes from the next decade of research into this area. 10 Henry Chen Henry Chen 4 months ago As Mr. Charles Miller puts it: "The best lecture on this topic I've ever heard! Thank you Dr. Carroll. I envy your students!". Yes, if I had Dr. Carroll to be my quantum mechanics professor back 60 years ago...... 1 akshat verma akshat verma 4 months ago (edited) Sean with his articulation and approach, must have caused a lot of listeners to get selectively entangled with versions of world/s, where we have a better understanding of quantum mechanics Mark Brierley Mark Brierley 5 months ago What an excellent lecture - on so many levels. 1 Christian Libertarian Christian Libertarian 1 year ago This has actually been a step forward. It seemed to me that physics had hit a cul de sac with string theory and super symmetry. They really wanted that stuff to work—it just didn’t lead anywhere. This version of quantum gravity has some calculations yet to be done. Maybe it will work! 6 Jolanta Rey Jolanta Rey 1 year ago Thank you for this fantastic lecture! I have listened to everything YouTube has to say about Quantum Mechanics but this was by far the easiest to comprehend for a lay person.. I still like the Copenhagen Interpretation the most. 4 PurpleV2 PurpleV2 1 year ago Great talk and presentation! I love Sean Carroll's open-minded attitude - somebody who asks the questions and explores answers to get together closer to truth and not just for the sake of proving the theory. Basically what science is all about. Based on mankind's accomplishments I assume this is how most scientists operate. Unfortunately as a casual I see more of the scientists who'd create a lot of assumptions and additional theories to prove that one theory no matter what. But in my opinion the multiverse theory in this context is too vague. If I'm not mistaken, this would ignore the "cause" of an action and reduces the universe to randomness. It can't stand on its own as there are clear cause-action relationships and this theory doesn't actually explain them, if I didn't miss something. I believe in quantum physics mankind simply lacks missing information. We look at it from our former perspective only. We can't assume we identified all variables that lead to matter. Neither there is a clear way how to measure the unknown. 14 C Joe C Joe 3 months ago Brilliant job! I did a little physics study in college years and still I am thrilled to hear the latest report on subjects like this. Sean is fun to listen to more than once. I have watched this one twice. 2 David Walker David Walker 1 year ago its been over 100 years since we discovered the quantum world and the more we try to get to the bottom of it the more incomprehesible we find it. I think we shoud just accept it as it is 4 K. P. Redmond K. P. Redmond 4 months ago Thank goodness for YouTube. I can stop Sean's lecture, look up words, and replay the last section. If I had been sitting in the audience I would have been totally lost. The quantum world is a wonderful mystery! e.kab. e.kab. 9 months ago Having little information on the full breadth of all scientific fields, my philosophy on quantum mechanics has remained pretty consistent, to me standard physics has reached somewhat of a plateau in obtainable knowledge of the fundamental mechanics so alot of study has been pushed toward the manipulation of those mechanics, quantum mechanics seems to inherently be the next frontier...the relationship being reality vs. potentiality and the correlation between the two, whether we believe in it or not quantum mechanics is a cog in the machine, helping to layout every moment, it's silly to ignore what's Infront of you so I respect and applaud Mr. Carroll for being so adamant about pursuing the study 1 Matthew Chan Matthew Chan 13 days ago magical how he explains such difficult concepts to a layman like myself--thank you! The Royal Institution Marc Marc Marc Marc 2 years ago (edited) Sean Carroll is back! Edit: Just found time to watch this amazing science communicator return to the RI (this time without his wife). The talk has forever changed the way I think about quantum mechanics and the universe. A very memorable talk that tempts me into buying his new book "Something Deeply Hidden". I thought it was such a bold move by Prof. Carroll; to take these quantum mechanical "interpretations" and make them 'theories'. Its exactly what this field of science needs right now. Creating new theories based from entanglement and getting people to stop using classical mechanics as a starting point would forever change physics. Thanks again to the RI for bringing back Sean Carroll for another insightful lecture! 130 Steven Meiklejohn Steven Meiklejohn 5 months ago That was just terrific. Entertaining, informative and understandable to the layman. 2 Dragoljub Martinovic Dragoljub Martinovic 1 year ago Sean is the genius for explaining and teaching sophisticated issues!!! God bless Him!!! 7 never again never again 11 months ago Great presentational skills, enjoyed this very much! Thank you! 2 Owais Lone Owais Lone 11 months ago Such a great talk for someone like me who is a physics layman and more of a "picturesque" person than a mathematical one. 1 Victor Hugo Ventura Victor Hugo Ventura 10 months ago Excellent speech, thanks professor Sean 1 Harry Verey Harry Verey 3 months ago Extraordinarily engaging lecture on such an incomprehensible subject . Amazing. 1 Sandrine Deglin Sandrine Deglin 4 months ago Outstanding lecture. Thank you! Lee Matthews Lee Matthews 1 year ago One of the best lectures I ever attended at the RI, Sean's a natural. 51 Salesforce USA Salesforce USA 1 year ago Thank you for covering a vast and difficult area. You did the best. 5 Techy TyGuy Techy TyGuy 4 months ago Can the gravitational wave in the space divided by time account for the 2 particles spinning in opposite directions (up and down) be derived from the decay of the Higgs boson? Like the peak of the gravitational wave be the clockwise/upward and the trough of the gravitational wave be the counter-clockwise motion of the particle falling down? Citizen Of Earth Citizen Of Earth 4 months ago I loved this talk. Very informative. 1 Dennis Alvarez Dennis Alvarez 11 months ago The quote by David Deutsch made me break out in laughter. I listened intently. I don't mind saying that I find these concepts very difficult to wrap my head around. At the same time, I don't doubt them. Maybe by the time I'm near the end of my life I'll understand just a little bit of this. I find it comforting that even the people who are espousing these theories don't completely understand them. 1 Michael Ayres Michael Ayres 9 months ago Best quantum mechanics discussion I've heard. Fantastic 1 Daniel Gregg Daniel Gregg 2 years ago Superb!!! I've been telling people about this for a while, and now it is nice to see it coming in such a straightforward way from an authoritative source. 8 james gordon james gordon 1 year ago ...he’s very good in the way he presents this...I understood it and he answered some questions I had on this topic...bravo... 1 Ioan-Cristinel Istrate Ioan-Cristinel Istrate 1 year ago (edited) fantastic presentation, you dont need a great deal of physics to comprehend this. i am a supporter of the multiverse now.. i also do not agree with classical physics because exactly of the assumptions made by only observing things which the frame rate of the human eye is way smaller than of other beings.. is relative 1 adelew filkale adelew filkale 1 year ago Simplified, clear, and interesting explanation 1 silmar andrade silmar andrade 5 months ago Perfect lecture! Besides, his engligh is so clear that I could understand more than 90%! Thank you for sharing! 2 SUBHANGAM DEV SUBHANGAM DEV 9 months ago (edited) Brilliant explanation Sir. I would like to write down my perception about the Quantum Superpositioning (When somebody looks it changes, and when somebody does not looks it continuous its regular multi state of appearance at a single point of time, ie for example; appearing as a circle, a rugby ball and a flattened ellipse at the same point of time elapsed). According to my perception When I look at a quantum superpositioning state of mechanism occurring at the real time, my glance (or the respective onlookers glance) incites a reaction into the object of superpositioning. How? When we look at something, our eyes starts to emit photons at the glanced object and those emitted photons from the onlookers respective eyes triggers a electro photonic reaction which intervenes with the super positioning mechanism and the onlooker witnesses the changed condition (due to the photons released from the human eye towards the object). This changed condition can explain the quantum super positioning of multistate occurring and re-occuring of more a circle, a rugby shaped ball and a flattened elliptical ball at the same point of time. The photons emitted while we look at anything according to my perception does get automatically involved into a photon-electromagnetic reaction which distorts or changes that onlooked object by the electro wave and particle functions simultaneously or parallely. Quantum Tunnelling can provide a precise explanation about the Copenhagen effect. Quantum entanglement, Quantum Tunnelling & Quantum Superpositioning if researched together can solve the Copenhagen effect of Quantum super positioning. This above explanation is my perspective of the weird change in the onlooked objects behaviour in multi existence of different states at the same point of real time occurrence. I have only submitted my perception and my explanation is not any declarance of anything new as I am a student of commerce not science. I express my gratitude to everybody related with this particular video as it instilled a massive triggering effect on my curiosity towards quantum science. Thanking everybody. Subhangam Dev 🔘🔴🔻 2 月下彼岸 月下彼岸 1 year ago The idea of linking quantum entanglement with spacetime-geometry/curvature is just so fascinating. 69 goongoos goongoos 3 months ago Excellent, engaging explanation of quantum. Not easy to follow but it does sink in. 2 Abiston Services Abiston Services 2 years ago A great speaker to explain in reasonable terms to a person who at least has the basic knowledge, and not a scientist! 👍 12 JF C JF C 1 year ago Absolument extraordinaire !thank you for this so clear conference . 2 Michele Righetti Michele Righetti 4 months ago An amazing speach. Looking forward to a proper formalization of the theory SquidProQuo SquidProQuo 4 months ago Wow! This guy is on the right track to solve the gravity, and dark matter problem. Mark Barkell Mark Barkell 4 months ago Thank you for the explanation of superposition along with the many-world's and "thickness" of probabilistic being known as existence. Throughout the discussion of gravity, I keep on wondering nearness -- I wonder what types of space we are thinking Euclidean or space with donuts and coffee cups, or even more holes. And, then, are holes modes? Alas, such fun useful things which will only be useful once we figure them out better or just use them more. Keep good records and keep planning experiments. Look forward to hearing more. I suppose I might find out more about space if I bought the speaker's book; along with reading it. :) whynottalklikeapirat whynottalklikeapirat 8 days ago I took my car to a quantum mechanic. It’s currently in an indeterminate state, but worse - it’s being so in numerous other branches of the multiverse. I shudder to think of the sheer accumulated entropy of the eventual bill. The Royal Institution Raver Operator Raver Operator 1 year ago (edited) Wow! not sure how I came about your video here but I watched it start to finish and was fascinated! Thank you for such a brilliant lecture!! ♥️ No uni student here but found this fascinating and a great description / understanding of such a complex science, kudos!! 🙌🙌 3 Sam Gordon Sam Gordon 1 year ago This has to be one of the most important lectures, if not the most important, in the entire universe or universes to date as far as we know. Chris Johnson Chris Johnson 2 months ago Great lecture, love the book too! Cathy Hanson Cathy Hanson 1 year ago I want a whole lecture on what Sean was talking about in the last few minutes! 1 Neil Langdale Neil Langdale 1 year ago (edited) Really loved listening to this, so my interpretation is that where you are in some kind of multi verse. does that mean when we dream that our dreams could be interpreted of a visual situations of different existences ? 1 hotdog hotdog 4 months ago Love these 1 hour talks. At the end I can string half a sentence together to make myself look smart, in company that is smarter than myself. EDWARD RICHARDSON EDWARD RICHARDSON 2 years ago Outstanding. I love when people are great speakers. A good lecturer can keep you interested, get you laughing here and there, but a great energetic speaker with a great voice carries you along on a wave of modulation - this man is that. 9 Thunder Bug Creative Thunder Bug Creative 11 months ago (edited) Quantum physics is something I call “harmonic simulation theory”, it just doesn’t know it yet. Instead of quantizing classical descriptions or even starting with quantum theory, what if instead we started with a single question: What would the environment, space, or time look and feel like to an individual neuron of code, traveling one molecule of silicon, inside a single nano chip, inside one microprocessor, inside an individual simulation, inside a program, inside of a super computer? Clarity Environment Clarity Environment 4 months ago Great lecture. As a chemist who's learnt the "what I need to pass the exam" version of QM this is very interesting for helping to fill those annoying gaps, BUT for me there's a leap of faith and tautology in the many worlds/universes theory proposed. If I want to drive somewhere, I put my destination into google maps and it gives me a route (I always choose the simplest quickest route), my wife always chooses the most economic however tortuous. My map software is not fully up-to-date and sometimes I make a mistake alerted politely with route changed, recalculating. When I get into the car, the many worlds model contains all the possible routes that I could take to the destination with their attendant probabilities. If my wife gets into the car, then the probabilities change significantly, and they change again if she gets into the driving seat (she isn't so good at following google map instructions) or if my daughter is driving who never makes a mistake. Once we arrive at the destination we know exactly which route we'd taken and it was deterministic - with the same mindset, levels of concentration, driver etc. the same route would be repeated. I don't see the need for many worlds/universes and realities - the time passing (always in one direction) on the journey glued into history the route we'd taken as we took it. This is probably a rookie error question, but why are many worlds needed in QM instead of time just time locking in the events that happened in the one universe. 2 Rafe Bundy Rafe Bundy 1 year ago This blew all of my many minds - what a great guy 7 Hearrok Hearrok 1 year ago I have an important question. Has anyone tried to check if the particles return to state of superposition after the measurements have stopped? Because IF they do return to their superposition, that could imply that there isn't actually multiple universes, but instead the same particle is just "spinning" until observed. Let's play with the thought that the particle ends in state A. If the particle then returns to it's superposition, does it always end up being state A again, OR could it switch states and become state B? The explanation would be that it's existence does not split every time observed. More like that it's state gets frozen in the current moment. And for that it doesn't have to be multiple copies, just one and same particle changing states. Meaning it's not two particles, just one that is oscillating between two states and the oscillation it self creates a wave/pulse. Because as most other things in life, stuff that oscillates tend to produce waves. 3 Zula Manavraj Zula Manavraj 11 months ago Thank you very much ...I want to be quantum physicist and I will surely appreciate the idea that our world is purely quantum mechanical ....that we must find out!!! 1 Álvaro MD Álvaro MD 1 year ago What an amazing talk. Such a pleasure to watch it. I couldn’t enjoy more. 132 The Royal Institution Jason Brooks Jason Brooks 7 months ago Fantastic!! First lecture of Sean’s I have ever seen. Enjoyed all of it… just so easy to follow and fun to watch. Outstanding job all all around. Bravo! 3 Evan Penny Evan Penny 2 years ago Great lecture. Love your enthusiasm. Of course the inability of the current theories to encompass what we think we know about the universe attests to the inadequacy of these theories. Good luck with trying to sort this all out. 5 Beena Plumber Beena Plumber 4 months ago Such a humble guy, and such a gifted lecturer. Who would think he was the one sent forth on this earth to shake the foundations of modern physics? He didn't invent Many Worlds or QFT, but he's the one putting the pieces together in a way that makes sense, and he's rattling the cages of the complacent. What a gift to science! 1 Rachel Brown Rachel Brown 6 months ago Absolutely the best presentation I have seen on Quantam Mechanics anywhere in the past 20 years. 6 edgeeffect edgeeffect 6 months ago Anyone who owns a cat will know that they really ARE in a superposition of awake and asleep at any point in time. 154 Amedeo Filippi Amedeo Filippi 1 year ago Excellent lecture!

What possibilities this could open for our species . But , an urgent request from an old guy who has been following this subject all his life . Will you please BLOODY GET ON WITH IT , as I am desperate to know the answer before I croak . 5 Aashutosh Sharma Aashutosh Sharma 1 year ago Thank you for this excellent video/lecture. Proffesor Carrol is a true blessing. His works are of the same quality as this lecture. I loved his book Spacetime Geometry and General Relativity, it was a great pleasure to read and work through his book. Stephen Martin Stephen Martin 11 months ago (edited) I am the embodiment of Schrodinger's cat: I am superpositionally both glad that I watched this video and not glad. Glad because this is a window into the truth about reality. Not glad because I suspect that the closer one is to the truth in quantum mechanics, the closer one is to going completely insane. zichbold zichbold 4 months ago I am always suspicious when someone gives a lecture on a difficult scientific topic, and afterwards the audience raves about how well the speaker explained everything. They would finally understand. In such a case, the lecturer just gave the audience the wrong feeling that they understood something. But if you take the test and let people reproduce what has been said, let alone apply it to a specific example, it usually turns out that they have not understood anything. People are much better at praising than at understanding. 4 Erwin Hayen Erwin Hayen 7 months ago (edited) Great stuff. Thinking out of the box…., in which previously a cat was presumably hiding. 😉👍 Love the challenge of the white spots on the map. M.K.C.

My incomprehension of quantum mechanics seems so much clearer now. 2 Alien Ai Alien Ai 10 months ago I wish I could have a professor like Dr Carroll he speaks so clearly 7 maxthemagition maxthemagition 11 months ago Excellent lecture. Got me thinking about klystrons, where electrons are concentrated into a beam and accelerated from a cathode to an anode in a vacuum by a potential of about 10Kv and a magnetic field through cavities (of which there are 4) and a length of about 1 metre.... An input r.f. excitation at the first tuned mecahnically cavity of about 1 watt at 600Mhz ends up at the final cavity at 25Kw!!. Here is an example of trillions of individual electron fields (rather then particles.??), being controlled and manipulated by electric charge (volts) and a steady controlled magnetic field. I suppose particle accelerators the same. The thing is that the "fields" are being used and controlled So researching control of fields may lead to something useful as did Klystrons....they were used universally for broadcast TV, until digital TV came along... Santosh Vaza Santosh Vaza 1 year ago The wave function collapses/forms when the observer is of the opposite nature. So if the observer is made of atoms/particles, wave function will collapse into an approximate point. If the observer is a wave then wave function will form back if it were collapsed Lies Kató Lies Kató 2 years ago I was so afraid when I saw the title, that I would not understand one bit of this - but it was explained so great and with so much enthusiasm and clearness, that even a Humanities scholar of Very Little Brain and with English as second language like me could follow (and, of course, love it). Thank you, Royal Institution, and thank you very much, Sean Carroll! 13 Milán Fodor Milán Fodor 4 months ago I never believed in role models but Sean Caroll is making me doubt myself...he is such a great speaker and has the smartest attitude towards life and science in my eyes! If you don't listen to his podcast you are missing out! Paige Chamberlain Paige Chamberlain 1 year ago Thank you for properly interpreting the cat experiment. It's hilarious to see all the physics "nerds" wear a cat t-shirt and talk about it like they understand it. 1 sarzotti32 sarzotti32 4 months ago My son is always coming home, though he never really leaves, still I miss him everyday. There’s a phantom-like quality to all phenomena. Like Quantum Mechanics, Dependent Origination, demonstrated above, is in fact believed in and acted upon constantly. Betting an ‘over’ and an ‘under,’ and several other possible game outcomes all at the same time seems to acknowledge, if not wholly imagine, ‘many worlds’ simultaneously happening. In Buddhism we start with Two Truths, ‘relative’ and ‘absolute,’ and in that way one doesn’t interfere with the other whether phenomenon comes or goes or never really exits in the way we, filtering ‘reality’ through our predispositions, wish it would. Ontologically, that way, one of having many preferences, requires paving the entire world with leather. Whereas the world seen ‘absolutely,’ or without relative predispositions, is like simply putting on a pair of shoes. 2 James James 1 year ago Back in the 1920's the universe split into multiple, parallel universes; in one universe, Bohr and Heisenberg are correct, in another, Einstein and Schrodinger are correct, in another, Everett is correct, and in yet another, Bohm is correct. In one of the universes, none of them is correct. Simon Anthony Simon Anthony 1 year ago Now, what about Entropy and information ? Could that be a function of the geometrical shape of entanglement? If it is, then what is observing all this ? I think we have to add information and whatever bothers about information in to the mix rather than ignore that too. szpinak222 szpinak222 2 years ago Just a reminder, Sean has a podcast on YouTube called Mindscape. He talks about everything from wine, conciousness, end of the universe to physics. Still, much of it is physics. 44 Enlil Annunaki Enlil Annunaki 3 months ago Brilliant! Probably the best hour I have ever spent on YouTube. 2 lammarkk lammarkk 11 months ago Brilliant talk, thank you. Carl Carl 4 months ago Fantastic lecture, made my brain hurt but in a good way, which is probably caused by quantum entanglement Narantsogt Baatarkhuu Narantsogt Baatarkhuu 1 year ago OMG! So gravitational attraction is an aggregation of quantum entanglement of matters on a macro level?! Wow! 1 F Utube F Utube 5 months ago (edited) In reality all electrons spin in the same direction, it’s just that some are upside down. In terms of quantizing gravity, if the strong force can get stronger as the distance increases (rubber band, gluons), why can’t gravity get weaker at the quantum scale? It obviously does otherwise everything would turn into a blackhole. Graham Carey Graham Carey 2 years ago My brain is too fossilised to be able to comprehend much of the content, but I still enjoyed this presentation. Entertaining, and informative. Thank you, RI and Dr Carroll. 13 tashawn2222 tashawn2222 4 months ago Great last third of the lecture to bring us to what he's currently researching and why. Chick Sage Chick Sage 1 year ago I was in a super position where my brain both hurts and doesn't hurt, but then I became entangled with the environment. So, when you open the box, you will find me and my brain already hurts, because Dr. Carroll was in my environment lol Thank you Ri, for another great video. peace 8 Scot Owen Scot Owen 4 months ago This is a tenacious discussion of Q.M., with the goal of presenting his favorite interpretation. At 16:00 he heads the column "when someone looks". Nobody has to look. A robot can "look". Any machine can "look". Any interaction of the system with many particles is "looking". That is, irreversible interaction with a macroscopic system. Lugul banda Lugul banda 1 year ago fantastic lecture, love it, thanx EclecticInstinct EclecticInstinct 4 months ago Second time watching this. I wish I could give it a second thumbs up.

Arthur Vandelay Arthur Vandelay 1 year ago Not sure I'm capable of understanding quantum physics, but I now know more about cat boxes than I dreamed possible. 1 Kaushik B 11 months ago Great lecture 👏 L Dewey MD 2 years ago (edited) Wow. It's been a long time since I've listened to Sean Carroll. This lecture by far is one of the best I have heard on this subject. Dr. Carroll presents an intriguing and fascinating picture of the problems with understanding quantum mechanics. Just might buy his book! 10 Stephen Morton 1 year ago Thank you, what an excellent speaker unquestionable 11 months ago The brief lecture on Quantum Mechanics is 56 minutes. Imagine a long one… 12 julio velasco 4 months ago The father of Quantum Mechanics was really Paul Dirac (1935) and the fundamental problem of the day was that the theory of Electricity and Magnetism was not completely satisfactory. Rory Blake 1 year ago I feel that the cloud chamber is too small to detect radiation waves. The waves must extend much wider. The artifacts exhibit as straight lines when they are not. This, would make quantum physics better align with the real world. Jaseth Connor 1 year ago I feel like I have an advantage going in to these studies having a background in magnetic particle inspection. Also me: wayyyyyyy behind in mathematics 😆🤷‍♂️💬 Gordon Hill 1 year ago Every time Sean wants to solve a problem he invents another universe. Under that condition we should solve every problem in no time. 3 Randolph Vusi W Dube 1 year ago I think this explanation of quantum physics et Al discussed should be taught in school... Loved it, thank you. Anahita Alehabib 5 months ago The best lecture on this topic👍 Robocop2015 11 months ago Great lecture! Dan Fry 3 months ago This is a superb presentation.
