came for quantum mechanics, stayed for the strange river man
yeah....his "explanation" feels quite indeterminate.
It's like he's there but not there at the same time.
LMAO
Is he naked? Lol
Is it me or is there a caveman in the background that just discovered a river?
... and at 5:20 he's taking a leak as well.
The canoe people starts hunting him at 8:15
Yeah a naked cave man! Where the fuck were they filming this??
Very distracting. And he forgot his loin cloth.
No he is part of the quantum theory, he is there and not there at the same time 🤪🤪🤪🤪😂😂😂😂
I was very upset when I realized that in my physics degree they had taught me the Copenhagen propaganda as though it was fact. My discomfort with the material brought me to research deeper and then I realized there are so many other interpretations and that the Copenhagen interpretation was only accepted by 30% of the world's physicists (the majority at the time) pilot wave is surpassing Copenhagen currently for the majority of acceptance. But what troubles me the most is that they don't seem to care about finding out what is actually going on, so they have effectively become quantum engineers rather than quantum physicists. We need a little dose of philosophy to slap us back to the process of discovery.
Schroedinger's Streaker making his quantum appearance.
Chilling in the forest, skinny dipping in a river, waxing poetic about theoretical physics. What a life. 😎
"It would be nice if every student who learned Quantum Mechanics at least got a three page accurate description of the situation, right? If you really want to understand the foundations then you have have classes in foundations. ..Physicists have this idea that because they have a physics PhD they must know all these answers. But then you have to ask well, where did you learn it? It wasn't in your textbooks. You never learned foundations. You never took a course in it. You never read a chapter about it. You never read a book about it. Why do you think you know about it?"
Tim Maudlin is so refreshing to listen to. He is such a clear and incisive thinker on these matters, and he has the degree in Physics to back it up.
This is one of the two or three places right now where a field of science desperately needs philosophers like this to analyze the conceptual foundations. I mean, seriously, why would anyone say out of one side of their mouth "quantum mechanics is extremely well verified by scientists in laboratories" and then out of the other side of their mouth say "the best interpretation of that data entails that there are no laboratories or people". It's just cognitive dissonance, and John Bell saw that. Tim Maudlin sees it too and I hope people will listen.
What a great background for this interview. Even the bird's chirping added to the overall production value. Also, the interviewer's questions and follow up questions were as good as the answers received from this clearly learned and passionate academic.
Very refreshing to hear his take on Bohr. Exactly what I've always thought but couldn't quite articulate.
Tim, I couldn't agree more. I think that any unified theory will have to be constructed around a proper conceptual model of how nature works.
I think the key to figuring out an actual quantum theory is achieving a better understanding of what time and gravity really are. What I've been thinking about is time is seemingly regarded as a single thing, yes distorted by gravity, but none the less it is still seen as a single universal thing. What if this isn't the case? What if all matter has it's own separate time. That time isn't a property of space it's a property of matter. On a macro scale gravity unifies time making it seem as though it were a property of space. On the quantum scale where matter has very little or no mass gravity is not unifying this material's time with the macro world. In stead very low mass material mostly runs on it's own time and only occasionally has it's time synced to the macro world when it interacts with it.
When we observe these low mass particles our interaction syncs them to our shared time and so to us they appear to behave like, well, particles. If we don't observe them then they're flying on their own clock and to us they can now seem like a wave of possibility because where they are and where they are going and how time is unfolding for them is disconnected from our gravity unified time.
Same goes for quantum entanglement. Entangled particles connection is they are sharing the same time that is separate from our time. All the spooky action at a distance is because we perceive the particles as interacting instantly, but the interaction is really occurring in a separate time that is unfolding differently than our time. This explains even weird crap like quantum erasure where is appears entangled particles communicate retroactively to behave like a particle or a wave. When we choose to observe the experiment the interaction syncs the particles to our time, but until that happened from the particles point of view neither had yet impacted a detector. When the observation syncs them to our time from the particles point of view they are hitting the detectors at the same time.
..Or maybe I'm totally wrong :)
Im sorry, that was me in the background, I was testing the quantum wave theory.
Tim looks like a member of the velvet underground.
Not one of the velvet but close.
He looks like Andy Warhol
Yup.
Mo Tucker?
Just like Velvet Underground. Only 100 people havd read his books. But every single one of them became an influential physicist
One of the best / funniest TH-cam comments I've ever read..
I thought he was the guy from the Goo Goo Dolls
This interview is amazing. This is the emperor without clothes. Great!
The "problem with quantum mechanics" has bothered me since my undergraduate days at Berkeley. While taking the fourth course in the undergraduate physics series there, around 1970, I was disappointed to discover that the physics professors and grad students, for whom I otherwise had enormous admiration, did not seem to understand quantum mechanics. I began to suppose that Berkeley was simply not up to speed in this particular subject. Then I spoke with a friend who had been at Cal Tech and had heard Feynman's point of view -- that nobody understands quantum mechanics. I said, "Well, someone must!" and he reiterated the Feynman line. I did not go on with physics as a career, but I have never stopped trying to understand the meaning of QM as a physical theory.
Ralph Dratman Good luck
Quantum mechanic would not be so perplexing if we took consciesness as a fundamental property of nature. But that goes against our Materialist world view which states that consciesness derives from matter, rather then the other way around.
When Feynman said "nobody understands quantum mechanics", what he really meant was "nobody has a fully intuitive classical like picture of what is going on in quantum systems". There is merit to the possibility that there may really be no classically intuitive physical picture of quantum mechanics, but that doesn't mean that we shouldn't still devote resources to studying the foundations of quantum mechanics,.
Thanks for sharing, did spent time on it too. End up brushing up my maths as a hobby, hoping to shed light on it.
I am currently a physics undergrad and will eventually do a Ph.D. and I agree with you that QM is quite complex and a bit hard to grasp only because it does not go with what we think is "normal". Till now I have an issue with the quantum interpretation of spin. I have seen many definitions and asked many great professors. I never found their answer satisfactory. Yet, these definitions work in the realms of our real world. So you can either go with the flow or decide to solve the missing puzzle yourself. In my case, I will go with the flow until I have enough knowledge to tackle things by myself. After that, I vowed that I will solve the missing puzzle in the logic of QM (at least for my understanding)
I would never let a physicist near my cats.
nor a philiospher near a nuclear reactor
Your too late. They're already thinking about your cats, and know they're hypotheticaly dead and alive. Just don't let any Russian physiologist around dogs🐶. They don't preform thought experiments on them.
It was very funny 😃
Well said - Philosophers, physicists and mathematicians need to talk to each other. This is how we get people who are experts in all 3 fields. This is how we get progress and understanding.
“Once you start doubting, just like you’re supposed to doubt, you ask me if the science is true. You say no, we don’t know what’s true, we’re trying to find out and everything is possibly wrong.”
― Richard P. Feynman
Well, there is no denying it . This is the most maudlin explanation of Quantum Theory out there today.
kagney13 well that does it, I’m officially devoid of all emotion.
An unfortunate last name to have.. Bahaha
A very refreshing attitude. As a layperson I have an intense interest in the boundry area between physics and philosophy so I end up looking for informative lectures and videos on TH-cam. I haven't found very many that don't exploit "quantum wierdness" as if that's what people want to hear.
This is the single best explanation of quantum mechanics I’ve ever seen. I’ve seen a lot.
Very interesting. I would love to hear Tim in discussion with Sean Carroll on this topic.
A problem is that physicists start to believe that the mathematics is more real than reality itself and extrapolate backwards to come up with nonsensical ideas about time.
Well yes...everything is an assumption built upon assumptions...I like to think about whether numbers actually aren't a mistake, will they still be around 10000 years from now or will we have more advanced ways of thinking about the universe? It seems likely that they will be around, because they probably have been here for 100,000 years or more but...it isn't a given.
Yeah, like that goofy fuck Albert Something who said that time is inseparably bound up with space, and that a pair of black holes might, in principle, make the kind of signal first measured almost a hundred years later by the LIGO experiment. It's a good thing there aren't more physicists like that guy.
Can you elaborate? What example are you considering?
Mathematics is a set of theories. Those theories can be used to explain probability, statistics, how numbers relate, geometry and so on.
Then physicists can use these theories in their tries to predict how nature works. The mathematics is just a tool
This argument resonates a bit with me.
What I have read of Quantum Mechanics strikes me as sort of incomplete; it's all about the *limits* of things, what we *can* know and *can't* know, working backwards from there.
I feel like it's like overlaying a picture and tracing its contours, then simply labelling the various blobs as "person", "tree", "car" etc - without bothering to fill in the colors or the shadows.
The image is "correct", yes, but there are certain dimensions of it that are missing.
Excellent Tim Maudlin!
Great interview. Efforts to silence debate seems to be the norm now, not just in physics but other sciences too and in social topics as well. When someone questions the established thought it feels empowering.
Lambda that’s covered in John’s second letter, ‘2nd John’- where we see report of a loose canon in the church, but despite the bad example set by him there is a hint that they should neither eject nor exorcise him. Mormons would do both, tho.
This turned out to be worth my time 👍
This 'silencing' hasn't occurred in my experience, but our university actually has a quantum foundations department, so we may be the exception.
except when it's about tesla, flat earth or electric universe.
Someone had to tell it at last.
This is the real problem with QM in general. To put it in terms of a philological analogy: QM has a lot of syntax but very little semantics.
the info "Professor of Philosopher at NYU" :P
The aspirin analogy is awesome and a great way to explain what's missing from current quantum theory. Another would be gravity. Newton's law of gravity told us how to calculate, but it didn't explain what was going on. Einstein's ToGR tells us what the physical underpinnings of the calculable phenomenon are. And, as a bonus, it made for more accurate predictions, especially in more extreme cases. Hopefully a true theory of Quantum Mechanics (as opposed to the mathematical recipes) will provide similar improvements to Quantum calculations. Great video - thanks!
@Plasma Matter natural fusion happens aswell.
Without the involvement of humans.
Sounds like the continuity of Gaston Bachelard warnings on QM teaching : This is one of the rarest and one of the most accurate talks I ever heard on QM, despite the fact I'm physicist. The only other author I know up to now who developed similar arguments was Richard Feynman. And obviously, most of the tools he developed were greedly used by his community, but all of the similar points he developed were quickly forgotten...
As a physicist, I can say that what the philosopher says at 16:00 is exactly correct. Very reasonable person especially his view on "power". We could not get a job about the foundation of QM simply because it looked hopeless as a question leading to no job.
He’s onto something very critical.
Great interview!
really good interview!
Tim goes wrong at @4:25. He dives into this mistake at @7:00. Bell's inequality falsifies local-realism. In lay terms, this means that (particularly defined) "locality" and (particularly defined) "reality" cannot co-exist. By saying "There has to be some non-locality.", Tim accepts "realism" uncritically. He confirms this when discussing the manifest image. But with critical examination, we cannot (yet) disregard either of those mutually exclusive options. In my understanding of the field, "locality" actually has the more compelling scientific credentials.
However, Tim is right about the character of Einstein. Albert was not at ease with considering "realism" falsifiable. And neither is Tim, apparently. General relativity provides the most compelling model incorporating "locality", to date. This must have been poignant for Albert. During his life, Bell inequalities were not yet experimentally tested. They are now. Therefore, while praising the poetic philosophy of Einstein, Tim rejects the crowning work that General relativity is.
That struck me as odd also. His comments on the "manifest image" suggest that he is committed to what Putnam used to criticize under the label "metaphysical realism". Maudlin also seems to speak of time, being either real or illusory, as if Kant never existed. His appeal to the primacy of the manifest image (although correct in a sense) is thus quite unfair even to Sellars who himself had a finer appreciation of Kant.
I think Philosophy is more important than ever in Physics, to help keep it on track, given the difficult and unintuitive nature of the high hung fruit.
We need a physical theory in quantum mechanics that predicts how reality works because mathematics won't tell you what caused that prediction though it predicts something very accurate. Mathematics shows you the effect but not the cause. That's why we need a physical theory.
Never knew Bon Jovi was a professor
Spooky action at a distance in the background at 2:40.
All of the problems found on phisics today may be solved with the aseptense that light multiplies by 10 in such a way light gets back fast. there must to be comunication but fast - They assume a particle may be in one place but wherever too - the solution is clear if light goes by 10 near to infinity fast imagen a band that goes fast and comes fast and that particle is moved forward and contrary now see it when it stops on one side and when stops on the other: no more spookie thing
Finally someone is telling what I was thinking for years.... And I was always said that I don't understand it because I see quantum mechanics too clearly. Pilot wave team here!
This is all very well but how exactly does he explain the the double split experiment?
There’s a naked guy wading behind him 😳
Maybe he’s got his feet entangled...
What he's talking about is the field of "ontology" which is the study of reality. The other two major branches of philosophy are epistemology (how we know what we know) and ethics (i.e. morality).
This video clip is 19:50 long but when you can see it's true nature which is a video file where do you put that time in? time is illusion for what we do or can not fully understand and what is not?
16:52 -> so true!
My application for PhD funding in the foundations of Quantum Field Theory (QFT) recently got rejected. Now I am turning to Solid State to get funding.
I am really looking forward to meeting Tim at Saig this July :)
Sascha Lill SL, why not try kickstarter? Put together some of your ideas and create some visualizations etc. This is so,ethimg I certainly would suppoert.
I hate Solid State so much. In my university, 90% of the physics department is doing Solid State and they made it a required course for all students.
Thumb nail had me like ,
Wtf does bon jovi know ?
Well done. I’ve always wanted to hear more about understanding physics not the application of.
a serendipitous poetic moment. we are all essentially paddling blissfully in a river! regardless! isn't that what Tim is saying?
Great interview -- it seems QM has become an odd mix of applied math and a religious furor demanding that the statistics and formula be accepted as literal reality...
Because it is dumbass.
Agree. These theories are just fairy stories written to match the evidence, and changed whenever the evidence seems to change. Which is okay, but it isn't truth.
Quantum Mechanics yields results that are 100% congruent with physical reality. Therefore it can be accepted as literal reality. What's your problem with it? It's called theory and experiment, and you don't need religious furor to trust it.
I don't think so. He seems to totally ignore the paradigm changing efforts of the experimentalists and his interviewer seems pretty clueless.
There is a problem not being talked about in this interview. That is 'what we can see'. We don't really have the capacity to observe at the sub atomic level. We see after effects of high energy events.. but we can't just look at normal stuff and observe with any real accuracy. This means we are lacking the capacity to 'fill in the blanks' regarding the foundations of QM.
If what he says is true, that there is resistance to this type of investigation, it means our knowledge won't be complete until we break the logjam.
QM equations predict a lot.. so we are reaping huge benefits.. but until we undergo yet another revolution in the capacity to observe, we'll be stuck (this process is part of the history of science.. where a revolution in observation power = a revolution in understanding).
The problem with people is that they try to compare behaviour of an elementary particle to behaviour of large objects. It’s as if you try to compare the life of a single person, to a lifestyle of a large family. Single person has more freedom and can do things independently of others. In a family , every member has impact, people co- depend and they behave in regard to each other. Not the best analogy but this is how I understand it.
When I was single, I could go out any time, come back any time. Stay all day in bed if I wanted, change my job , suddenly move to a different area, I didn’t depend on anyone .
When I got a family, I couldn’t go out without planing, bcz kids depending on me, I couldn’t change my job, I had to think about how it’s going to affect my income bcz I pay for school and in general have more experience, I can’t just change my location I think of areas where good schools are and so on. So as every member of my family, we interact and that restricts what we can and cannot do.
This is the simple way of putting it
The objective collapse theory is in fact at odds with the notion of... who am I kidding, go to the medium shot so I can see what the forest man is doing.
I like what this guy is saying. Mathematics can tell what will happen but not why. Perhaps we lack the cognitive ability to grasp the foundations. We naturally try to relate everything we understand about the quantum realm back to the macro world we are familiar with. But maybe there is a point where foundational realities are completely unrelatable.
Wait? Quicksilver became a philosopher?
yeah...this lookalike joke is still fresh on youtube, I was going to say Jon Bon Jovi
Breath of fresh air.
At this point, having tools to think about our world is so much more valuable to me than having a more efficient phone.
theotormon you can also overpay for technology to access free content.
Haha, yes it was rather maudlin 😆
Very interesting and he's absolutely right. Thanks for sharing.
Very interresting! Thanks!
Very good! A worthy endeavor.
The new book by Lee Smolin "Einstein's Unfinished Revolution" is about the very same problem.
Not just you, every normal person in the world wants to know. Only those who want to shut us up so they can have us just admire their mathematical prowess don't want to find out. They'd hate if we knew physically what is happening, then they'd have no more authority. We all want to know, but we'll live with the mathematical explanation if we have to, still hoping it will expose a deeper layer of meaning.
Everyone wants to know, but maybe knowing is not as simple as you or the professor wants it to be. Maybe knowing includes statistical knowledge, probability knowledge.
Thinking that nature can be reduced to some easy to get for any human explanation is most likely wrong and can most likely never happen.
Trying to simplify also often means certain parts of the thing getting simplified gets lost.
This guy is living on a prayer
well observed, not badly put...you could have taken the absurdity a bit further
He gives love a bad name, bad name
Praying has no proof of efficacy
He's half way there. imo
Bertrand, I think Bartholomew is saying he looks like Jon Bon Jovi.
Very nice interview, thank-you very much. I always appreciate the philosophical approach of Maudlin as opposed to the technical approach of physical science. Maudlin shows very well how philosophy remains very confused about the nature of physical reality even after 100 years of the very successful predictions of quantum science. Philosophy is really a discipline that asks questions without answers, then answers them, and then argues endlessly with other philosophers about the nature of physical reality. I like philosophy but I do not ever expect any answers to questions that have no answers.
Why are we here? Why are we here right now? Why is it us and not someone else that is right here right now? What is the meaning of life? What is the meaning of quantum mechanics? Why is the universe the way that it is?
These are all questions that have no answers, but are nevertheless useful to ask and discuss because that is what consciousness does. Consciousness is asking questions without answers and then continuing to find meaning in the endless discourse that follows. This is basically because we cannot always know the limits of what we can know even though we know there are limits to what we can know. We do need to keep asking and answering unanswerable questions in order to find the horizon of answers that we did not expect.
Topi up politics in England in a few days and I have 9913&
The streaker in the background has my full attention. This video just turned into a comedy for me.
He asks some very apparent questions that came to my mind almost immediatly after I learned about this almost shamanistic mysticism of quantum mechanics for the first time. I wonder why this isn't a topic all the time.
Very engaging interviewee and interviewer ... am subscribing.
Very crisp explanation.
Regarding how Bohr pushed the Copenhagen Interpretation...Exactly!
As a fan of science with some understanding of the concepts of quantum mechanics and relativity (but not at all, the math), I just wish I could find a a rigorous, scientific and mathematical analysis of the ideas of Nassim Haramein as conceptually those ideas seem to be rather compelling . But they are also, certainly, mind-blowing which may be why most of the searches I've undertaken to see if his ideas have been seriously considered turn-up either ad hominem attacks or simple dismissal with little if any reasoning as to the basis for the dismissal notwithstanding the detailed science and math which Haramein offers to support his theories.
I didn't know garbage could be mind blowing.
Scientific Theories have well defined attributes and limitations, requirements.
You can announce a theory on anything at all.
The theory or laws of Thermodynamics is a completely different animal to the subjective theory of say painting.
Quantum Mechanics is peculiar however in the sense that it is a stochastic based theory - non-deterministic in nature.
It spews out probabilities and invariably involves counter intuitive concepts - but nevertheless, it has no known counter examples in observation or experimentation that refute its main contentions etc.
This does not mean that a deterministic theory will not eventuate in the future that will be able to describe the same "quantum effects" defined today.
I bet string theory turns out to be just something that everyone works on because that way they can funding
The work of Bell showed that any deterministic model must be both nonlocal. More recent work however has managed to separate nonlocality from no ftl signalling, and so in a strange way it can be argued that it doesn't violate relativity. However that then begs the question, if it is possible for causal influences to propagate faster than light, why does nature seem to conspire in such a way as to prevent these causal influences from allowing us to send signals.
I want to say thank you to Tim Maudlin for presenting rather complex thoughts and ideas in a very clear and concise form. His approach is totally rational and I wish it gains attention and recognition from a much wider audience.
When the Copenhagen Interpretation has the final nail put in its coffin, physicists will look back on this 100+ year period with embarrassment.
Although even with delusions of grandeur, QM/QP has produced a lot of benefit and useful work (ie: "shut up and calculate"). But yes, from a theoretical perspective, its still a delusion.
No one looks back at Newtons Laws in embarrassment. Science knows that theories can be wrong and they can either be used to build upon on another theory or it can be discarded entirely. Hence why we keep verifying through experiments because we are not afraid to prove its wrong. Dumb comment.
Good sort of thinking there, I really liked it.
It is always with a bit of irony that I read about those who deny scientific principles in favor of some hypothesis that just so happens to sit within their own realm of understanding.
Theists are often adamant about rejecting Evolution or the Big Bang, and forget (or never realize) that it was a priest who originally developed the hypothesis that the Universe might have arisen like an egg, from some beginning, and that when people learned of this, the whole idea was dubbed the "Big Bang" as a joke!
When the hypothesis turned out to have merit, even the Pope was quite happy to think that our Universe most likely had a beginning event, and when people continued to doubt this as an absurdity, he even queried the priest about mandating that people now believe this "Big Bang" as church doctrine!
And yet today, most fundamentalists and many theists fight the idea of this "Big Bang Theory" as scientific intrusion into their religious dogma.
The same holds true for Quantum Mechanics: I see philosophers who debate that something they cannot comprehend should not be taught and learned as science, when the tools such as the computers being used to document their thoughts and allow an audience to consume their stories contain billions of transistors, none of which would work if it were not for the phenomena of Quantum Mechanics and the electron-tunneling that takes place at every P-N junction within every transistor.
Yes, there is a lot that science does not know. In fact, the Mechanism of Action for numerous widely-used drugs is still unknown even today, in this twenty-first century! And yes, up until the early 1970s, this even included aspirin, and today it still includes many drugs.
But just because some portion of why or how something works is still unknown, it does not mean that it cannot be quantified to indeed have certain behaviors and properties, just as the theory which attempts to understand the beginning of our Universe, or the equations that accurately describe current flow through chips of silicon. - j q t -
And now you sound like a scientific theist, why do you believe in anything beyond existence, why would you need anything more then the belief that you can observe yourself so that you can recreate the experience that created you. Without perception and belief of existence you couldn't exist, duality is our energy, without finite time you wouldn't be infinite. If something has a beginning it must have an end, time is radial, we could only be real for ourselves if time never changes, the universe will always recreate itself by believing it's observing itself, energy can be no less or no more then its infinite self, you can't add 1 to infinity, the universe can never change but it created itself by the belief in time but time can only exist if time is set as finite radial. I have written this message right now infinitely or it wouldn't be real for me and I wouldn't have my thoughts, the universe is just like a movie that replays itself infinitely.
Hunting for big game he is.
Great interview. I need to know more about what he thinks is behind the "curtain".
Refreshing interview on the subject. This horse has been beat to death over and over and this guy shares some refreshing perspective and critique of conventional stance on the subject. I really enjoyed this one.
Outstanding!!
FINALLY !!!!!! FINALLY !!!!!! FINALLY !!!!!! FINALLY !!!!!! FINALLY !!!!!!
BRAVO BRAVO BRAVO BRAVO
A thousand million thank yous, Tim !!!!!!!!!!!!!!!!!!!
The naked guy swimming in the background is a great touch.
I would recommend to Tim Maudlin and his audience to look up the Buddhist teachings on emptiness. Particularly Venerable Geshe Kelsang Gyatso Riponche's teachings on the phenomena. I think Tim is on to something here. Something that Buddhist Scholars/Masters have resolved through a practice of training the mind to obtain (for lack of a better word) a direct realization of all phenomena.
Thank you so very much!
We really need a physical theory!
We perceive 4 dimensions, 3 in space 1 in time, but what if we were blind to many others that are necessary for the standard model to work? What about more time coordinates?
Finally! I am really fed up with cheerleading of nonsense theories.
Not really a nonsense theory if it works lol
If you want to see such nonsense dismantled. Jim Baggot is great at that
"Shut up and calculate" sounds very much like Richard Feynman.
What moment results from matter translating in every direction at once due to the expansion of space. The same question regarding translation through time.
Give a medieval person a car, and they will easily learn to operate it and make predictions about it. Ask that medieval person what the car is or how it functions in fundamental ways, and that is where we are at with quantum physics.
Well thank you, I hear this stuff about time not being real, and it's always confused me, because I get older, and eventually I'll die, so to me it's always seemed that time is a stream that goes in a forward direction. Heavens, it's much easier to see this without the mystery, and to know there's probably a far more logical reason than we like to think. I feel much more free to think about it now, I'd stopped trying to, because I found it too mind boggling.
That was surprisingly good.
Congratulations excellent questions, marvelous answers. At last a professor of philosophy who sounds more like physicist than most Quantum specialists.
Epictetus the philosopher said: it is very difficult to learn something you think you already know. This is a huge problem to the Quantum theory physicists and academics.
so is this super simatry or multiverse approach?
...So how would we approach this theory? If ? there is a relationship between the observer and the observed?
There’s a big difference between the “manifest world” being an Illusion, versus it being Emergent. And I may be wrong, but I don’t think many modern theoretical quantum physicists still accept the former (if they even ever really did?).
Let see how this philosopher and physicist Sean Carroll debate.
He studied physics also. I would not dismiss him so eagerly.
dude carroll is terrible at debates honestly
Sean Carroll is a proponent of the multiverse/many worlds hypothesis... Tim Maudlin wins.
They may have on world science festival. Can't remember for sure.
They're on the same side, both pushing for foundations of physics to be more thoroughly studied. This guy likes Bohmian mechanics, Carroll likes multiple worlds, but both go out of their way to say they want to see the other options studied, too.
"is it like this?" is just about reconciling it with the model your brain makes of the universe based on sensory input. The predictive part is the theory. Reconciliations with the brain's model are exactly what "interpretation" is supposed to mean.
Physical: N/Kg = m/s^2, Electrical: W/N = Ohmm/Wb = m/FV = m/AOhmF = m/s, Magnetic: H/(Nm^2/C^2) = m/FH = m/s^2, Gravitational: H/(Nm^2/Kg^2) = Kg^2/(Nm^2/H) = Kg^2/A^2m.
The theory of everything will not be formulated without this key: Quantum waves are not physical and only hold the information for the object they represent. The quantum/classical divide can be crossed in two ways: The wave has a certain amount of information/complexity/size that it is always anchored to spacetime. The other is temporary with observation/measurement.
conjecture...so...ok.
The copenhagen interpretation treats the wavefunction this way, as being a mathematical construct that doesn't physically exist. It just represents total information about the system. Pilot wave theory on the other hand (and many worlds) treats the wavefunction as physically existing.
there is no duality
from thumbnail i thought i saw Jon Bon Jovi talking quantum theory?
Great interview. He says we must start with the manifest world. The datum we are most certain of is our awareness. I wonder if he treats consciousness as seriously as he does time...?
Time can be measured, it can be precisely defined and operationalized. "Consciousness" is vague, is it a thing or an activity? Is it a synonym for awareness? Or perception? Or is it experience? Or is it the experiencer?
I wonder if anyone knows anything i'm starting to have my doubts,
It's all a scam to make profit..
You know fuck all.
That is called "critical thinking".
This depends on which philosophical discourse you adhere to.
J.S. Bell posits a hidden variable, λ(t). The problem is that timekeeping, t, varies from location to location. There is no universal cosmic clock, t, that keeps the same time everywhere and everywhen in the cosmos. In the step where Bell cancels out the hidden variable, λ(t), he commits an error. Because twin particles separated in space age at distinct rates, they do not remain in perfect phase-lock synchrony. Instead of perfectly canceling to zero, there should be some kind of residual "beat frequency" that survives to the bottom line in Bell's Inequality. Indeed, in quantum computers, qubits are found to decohere in a matter of nanoseconds.
The reason that nobody (except sorcerers) can even ask for the foundations of quantum mechanics is simply because, as Einstein said it: it is pure sorcery!
Thank you Tim for shining a light so courageously and clearly on the Elephant in the room. (I had similar response from my lecturers during my Physics degree...so its exciting to see you raise these issues now)
So, can you please recommend a resource that will give an overview of the current thinking (Quantum Theories/ models/ foundations) under consideration?
Thanks a lot.
A good start is the wiki page for different interpretations of QM:
